Serving size, satisfaction influence food waste on campus

Multicampus study identifies problem's causes and potential solutions

RICE UNIVERSITY

HOUSTON - (April 2, 2021) - Understanding what drives food choices can help high-volume food service operations like universities reduce waste, according to a new study.

Researchers have concluded that food waste in places like university cafeterias is driven by how much people put on their plates, how familiar they are with what's on the menu and how much they like - or don't like - what they're served.

Food waste has been studied often in households, but not so often in institutional settings like university dining commons. What drives food choices in these "all-you-care-to-eat" facilities is different because diners don't perceive personal financial penalty if they leave food on their plates.

Published in the journal Foods, "Food Choice and Waste in University Dining Commons -- A Menus of Change University Research Collaborative Study" was conducted by a team of experts from Rice University; the University of California, Davis; Stanford University; Lebanon Valley College; the University of California, Santa Barbara; and the University of California, Berkeley.

Co-author Eleanor Putnam-Farr, assistant marketing professor at Rice's Jones Graduate School of Business, is available to discuss the findings and potential impact with news media.

The researchers conducted student surveys during the 2019 spring and fall semesters to study foods types, diner confidence and diner satisfaction. They used photos taken by diners themselves before and after eating to measure how much food was taken and how much of it went to waste. "Diners were intercepted at their dining halls and asked if they wanted to participate in a study about food choices and satisfaction, but the objective of investigating food waste behavior was not disclosed," the authors wrote.

The study found the amount of food wasted didn't significantly differ among types of food. Instead, researchers discovered waste was related to the amount of food diners put on their plates, how satisfied they were with their meals and how often they went to the dining commons. If students were satisfied with their food, they tended waste less of it. And diners who visited the commons most often -- making them more familiar with the menus and more confident in their choices -- tended to waste less.

Mixed dishes, like sandwiches or stir-fry, took up a greater percentage of the surface area on surveyed plates than animal proteins or grains and starches. Those three types of food took up a greater area of the plates than fruits, vegetables or plant proteins. The amount of food wasted, however, did not significantly differ among the various food categories.

The mixed dishes and animal proteins that took up greater portions of the plate tended to be pre-plated by the commons staff or have a suggested serving size. The study's results showed that greater amounts of food taken by diners correlated with the item being pre-plated or served by others.

The authors recommend future research on the topic uses their multicampus approach -- which enabled them to study food choice among a large and diverse group -- to better understand what causes food waste and find out if it can be reduced by interventions such as posting signs that encourage healthier choices.

Landslides: New early warning systems reduce false alarms

CMCC FOUNDATION - EURO-MEDITERRANEAN CENTER ON CLIMATE CHANGE

Research News

 

Many slopes in the Campania region are covered with layers of volcanic soil, the result of repeated eruptions over the course of millennia. As the impacts of climate change worsen, including the occurrence of very intense and short rainfall in localized areas, there is a growing need, especially in this and other Italian regions that are vulnerable to landslides, to understand the dynamics that induce such events more precisely and develop models that can predict them. When employed through adequate early warning systems, these tools can support decision-makers in adopting effective and efficient measures to protect people and the areas themselves from landslides.

To this end, the study Exploring ERA5 reanalysis potentialities for supporting landslide investigations: a test case from Campania Region (Southern Italy) by the CMCC Foundation identifies the potential of the fifth generation of atmospheric models (known as reanalysis dataset ERA5) developed by the European Centre for Medium-Range Weather Forecasts for improving the performance of early warning systems used, for example, by the Civil Protection (Protezione Civile).

On a slope covered by pyroclastic soil landslides are usually caused by a combination of two factors: the antecedent slope wetness conditions and the triggering condition represented by an intense precipitation event. The early warning system currently used by the Campania region uses the latter as the only indicator, ignoring the antecedent conditions of the soil. As a result, every time a precipitation event of a certain intensity is forecasted, whatever the state of the ground at that specific moment, the system returns a state of alert, pre-alarm or alarm. This increases the likelihood of false alarms and therefore of decisions - such as road closures - which may cause interruptions to services that in some cases could be avoided.

"Reanalyses are atmospheric models, the same ones that are used for forecasting. But they are usually used in back-analysis to reconstruct past weather conditions," explains Guido Rianna, CMCC researcher and co-author of the study. "Because of this characteristic, the purpose of reanalyses is not to forecast, but to homogenize, from a spatial and temporal point of view, data from different in situ monitoring systems - such as weather stations - or from remote sensing, such as satellites."

The fifth generation of reanalysis (ERA5) has a much better spatial resolution than the previous ones, providing atmospheric variables on grid cells of about 30 km side. In addition, it is possible to access free daily updated data through the Climate Data Store of the Copernicus Climate Change Service. This data ranges from 1979 up to 5 days before the consultation. Such a short time of data release allowed the authors of the study to assume - and then verify - a good performance of the tool not only for back-analysis studies but also for operational purposes such as the development of early warning systems.

"We first verified the reliability of the ERA5 reanalysis in reproducing rainfall histories leading to landslide events that actually occurred in the studied area," says Alfredo Reder, CMCC researcher and first author of the publication. "Next, we analysed the specific landslide event that occurred in Nocera Inferiore (Campania) on 4 March 2005. We verified that, at that event, the soil moisture estimations offered by ERA5, although not free of constraints and limitations, would have been able to observe a very high value in terms of water content along the entire cover. Thus, we have been able to take the final step of evaluating the possibility of using these reanalyses operationally for an early warning system. In the last phase of our research, we verified that the ERA5 datasets, if used as a proxy to support a decision, could improve the reliability of the forecasting model currently used in Campania, because they can provide information on antecedent slope wetness conditions, which are a predisposing factor for a landslide event."

The results of the study suggest the potential of this tool especially for minimizing false alarms, while avoiding missed alarms.

"Any expert on landslides in pyroclastic soils would say that the occurrence of an intense precipitation event in September in Campania, happening on a soil in dry condition, can rarely trigger a landslide," concludes Rianna. "But to date there is a lack of quantitative observational support to affirm this. Today, a Civil Protection decision-maker, on the basis of existing studies in the literature, could not fail to sound the alarm in the event of a forecast of a precipitation event with certain characteristics: he could not support this choice with data on the state of the soil in the prior period (except for a few limited slopes). Our research shows that ERA5 could fill this gap and therefore minimize the number of false alarms."

The results of this research apply to the case of pyroclastic landslides, which are characteristic of the studied area. The next step will be to verify the suitability of ERA5 reanalyses for the same purpose but in the case of other soil types, such as clay soils leading to slow landslides, which are characteristic of various areas of Italy, such as the southern Apennines and some areas of Basilicata and Campania.

Keeping it fresh: New AI-based strategy can assess the freshness of beef samples

Scientists combine spectroscopy and deep learning in an efficient technique for detecting spoiled meat

Although beef is one of the most consumed foods around the world, eating it when it's past its prime is not only unsavory, but also poses some serious health risks. Unfortunately, available methods to check for beef freshness have various disadvantages that keep them from being useful to the public. For example, chemical analysis or microbial population evaluations take too much time and require the skills of a professional. On the other hand, non-destructive approaches based on near-infrared spectroscopy require expensive and sophisticated equipment. Could artificial intelligence be the key to a more cost-effective way to assess the freshness of beef?

At Gwangju Institute of Science and Technology (GIST), Korea, a team of scientists led by Associate Processors Kyoobin Lee and Jae Gwan Kim have developed a new strategy that combines deep learning with diffuse reflectance spectroscopy (DRS), a relatively inexpensive optical technique. "Unlike other types of spectroscopy, DRS does not require complex calibration; instead, it can be used to quantify part of the molecular composition of a sample using just an affordable and easily configurable spectrometer," explains Lee. The findings of their study are now published in Food Chemistry.

To determine the freshness of beef samples, they relied on DRS measurements to estimate the proportions of different forms of myoglobin in the meat. Myoglobin and its derivatives are the proteins mainly responsible for the color of meat and its changes during the decomposition process. However, manually converting DRS measurements into myoglobin concentrations to finally decide upon the freshness of a sample is not a very accurate strategy--and this is where deep learning comes into play.

Convolutional neural networks (CNN) are widely used artificial intelligence algorithms that can learn from a pre-classified dataset, referred to as 'training set,' and find hidden patterns in the data to classify new inputs. To train the CNN, the researchers gathered data on 78 beef samples during their spoilage process by regularly measuring their pH (acidity) alongside their DRS profiles. After manually classifying the DRS data based on the pH values as 'fresh,' 'normal,' or 'spoiled,' they fed the algorithm the labelled DRS dataset and also fused this information with myoglobin estimations. "By providing both myoglobin and spectral information, our trained deep learning algorithm could correctly classify the freshness of beef samples in a matter of seconds in about 92% of cases," highlights Kim.

Besides its accuracy, the strengths of this novel strategy lie in its speed, low cost, and non-destructive nature. The team believes it may be possible to develop small, portable spectroscopic devices so that everyone can easily assess the freshness of their beef, even at home. Moreover, similar spectroscopy and CNN-based techniques could also be extended to other products, such as fish or pork. In the future, with any luck, it will be easier and more accessible to identify and avoid questionable meat.

NASA’s InSight Detects Two Sizable Quakes on Mars

April 2, 2021

NASA’s InSight lander used a scoop on its robotic arm to begin trickling soil over the cable connecting its seismometer to the spacecraft on March 14, 2021, the 816th Martian day, or sol of the mission. Scientists hope insulating it from the wind will make it easier to detect marsquakes. (Credits: NASA/JPL-Caltech)

The magnitude 3.3 and 3.1 temblors originated in a region called Cerberus Fossae, further supporting the idea that this location is seismically active.

PASADENA, Calif. (NASA PR) — NASA’s InSight lander has detected two strong, clear quakes originating in a location of Mars called Cerberus Fossae – the same place where two strong quakes were seen earlier in the mission. The new quakes have magnitudes of 3.3 and 3.1; the previous quakes were magnitude 3.6 and 3.5. InSight has recorded over 500 quakes to date, but because of their clear signals, these are four of the best quake records for probing the interior of the planet.

Studying marsquakes is one way the InSight science team seeks to develop a better understanding of Mars’ mantle and core. The planet doesn’t have tectonic plates like Earth, but it does have volcanically active regions that can cause rumbles. The March 7 and March 18 quakes add weight to the idea that Cerberus Fossae is a center of seismic activity.

“Over the course of the mission, we’ve seen two different types of marsquakes: one that is more ‘Moon-like’ and the other, more ‘Earth-like,’” said Taichi Kawamura of France’s Institut de Physique du Globe de Paris, which helped provide InSight’s seismometer and distributes its data along with the Swiss research university ETH Zurich. Earthquake waves travel more directly through the planet, while those of moonquakes tend to be very scattered; marsquakes fall somewhere in between. “Interestingly,” Kawamura continued, “all four of these larger quakes, which come from Cerberus Fossae, are ‘Earth-like.’”

The new quakes have something else in common with InSight’s previous top seismic events, which occurred almost a full Martian year (two Earth years) ago: They occurred in the Martian northern summer. Scientists had predicted this would again be an ideal time to listen for quakes because winds would become calmer.

The seismometer, called the Seismic Experiment for Interior Structure (SEIS), is sensitive enough that, even while it is covered by a dome-shaped shield to block it from wind and keep it from getting too cold, wind still causes enough vibration to obscure some marsquakes. During the past northern winter season, InSight couldn’t detect any quakes at all.

“It’s wonderful to once again observe marsquakes after a long period of recording wind noise,” said John Clinton, a seismologist who leads InSight’s Marsquake Service at ETH Zurich. “One Martian year on, we are now much faster at characterizing seismic activity on the Red Planet.”

Better Detection

The winds may have quieted down, but scientists are still hoping to improve their “listening” capability even more. Temperatures near the InSight lander may swing from almost minus 148 degrees Fahrenheit (minus 100 degrees Celsius) at night to 32 degrees Fahrenheit (0 degrees Celsius) during the day. These extreme temperature variations may be causing the cable connecting the seismometer to the lander to expand and contract, resulting in popping sounds and spikes in the data.

So the mission team has begun trying to partially insulate the cable from the weather. They’ve started by using the scoop on the end of InSight’s robotic arm to drop soil on top of the domed Wind and Thermal Shield, allowing it to trickle down onto the cable. That allows the soil to get as close to the shield as possible without interfering with the shield’s seal with the ground. Burying the seismic tether is in fact one of the goals of the next phase of the mission, which NASA recently extended by two years, to December 2022.

Despite the winds that have been shaking the seismometer, InSight’s solar panels remain covered with dust, and power is running lower as Mars moves away from the Sun. Energy levels are expected to improve after July, when the planet begins to approach the Sun again. Until then, the mission will successively turn off the lander’s instruments so that InSight can hibernate, waking periodically to check its health and communicate with Earth. The team hopes to keep the seismometer on for another month or two before it has to be temporarily turned off.

More About the Mission

JPL manages InSight for NASA’s Science Mission Directorate. InSight is part of NASA’s Discovery Program, managed by the agency’s Marshall Space Flight Center in Huntsville, Alabama. Lockheed Martin Space in Denver built the InSight spacecraft, including its cruise stage and lander, and supports spacecraft operations for the mission.

A number of European partners, including France’s Centre National d’Études Spatiales (CNES) and the German Aerospace Center (DLR), are supporting the InSight mission. CNES provided the Seismic Experiment for Interior Structure (SEIS) instrument to NASA, with the principal investigator at IPGP (Institut de Physique du Globe de Paris). Significant contributions for SEIS came from IPGP; the Max Planck Institute for Solar System Research (MPS) in Germany; the Swiss Federal Institute of Technology (ETH Zurich) in Switzerland; Imperial College London and Oxford University in the United Kingdom; and JPL. InSight’s Marsquake Service is a collaborative ground service operation led by ETH Zurich that also includes on-duty seismologists from IPG Paris, University of Bristol and Imperial College London. SEIS and APSS Operations are led by CNES SISMOC, with support of CAB, and SEIS data are formatted and distributed by the IPG Paris Mars SEIS Data Service. DLR provided the Heat Flow and Physical Properties Package (HP3) instrument, with significant contributions from the Space Research Center (CBK) of the Polish Academy of Sciences and Astronika in Poland. Spain’s Centro de Astrobiología (CAB) supplied the temperature and wind sensors.

Thousands dead and a country in turmoil: Brazil’s countdown to Covid catastrophe

With more than 66,000 deaths in March alone, Brazil is in the midst of a health and political crisis. How did the country get to this point?

The calamity currently unfolding in Brazil is off the charts. In March alone, 66,570 people died of Covid-19, while daily fatalities in the vast country currently account for about a quarter of the global total.

A highly contagious variant, P1, is now rampant and there are few measures in place to contain its spread, pushing health systems to the brink of collapse.

Perhaps unsurprisingly a political crisis is also brewing. The heads of all three branches of the military resigned this week leaving president Jair Bolsonaro - dubbed the Trump of the Tropics - exposed.

There are growing calls for his impeachment and a Bidenesque overhaul of the country’s coronavirus response.

But for many, witnessing the pandemic unfold over the last year has felt akin to watching a slow motion car crash. Experts say the foundations for the current disaster were laid soon after the virus first reached Brazil, in late February 2020.

Here, we look back at the key moments in Brazil’s countdown to catastrophe.
March: Bolsonaro meets Trump

In January and February 2020, as it slowly dawned on the world that a “mystery pneumonia” detected in Wuhan, China was a growing threat, president Jair Bolsonaro’s public statements already pitted the challenge as the economy versus the virus.

But his comments at this stage were “nuanced” and largely in line with other leaders, says Lorena Barberia, an associate professor of political science at the University of São Paulo.

And Mr Bolsonaro did not object to legislation, introduced before Covid-19 was first detected in Brazil on 26 February, that gave states a mandate to introduce restrictions and allowed for emergency quarantine measures to be adopted at a national level.

“But something appears to have happened in March, there’s a shift in discourse,” says Prof Barberia. “There’s lots of speculation that it’s linked to President Bolsonaro’s trip to Florida [to meet Donald Trump].

“In Miami Bolsonaro makes a speech claiming the pandemic is being exaggerated, and when he comes back to Brazil he starts to say other flus have killed more people,” she adds.

Members of Mr Bolsonaro’s delegation not only returned with Covid-19 infections, but a new approach.

April: Popular health minister fired

In the weeks after the Miami trip, as state and municipal governments set up coronavirus committees and taskforces, the national government did little to mobilise a coordinated pandemic response.

“This disconnect set us off on a bad track,” says Prof Barberia, adding that the lack of a clear chain of communication throughout the pandemic has allowed misinformation to spread like wildfire.

Then, in mid April, internal tensions burst onto the public stage when Mr Bolsonaro fired his popular health minister, Luiz Henrique Mandetta, following clashes over the coronavirus response. The move sparked protests in cities across the country, as people banged on pots and pans from their windows to express frustration, fear and anger.

“There was this struggle building and building,” says Ricardo Parolin Schnekenberg, a Brazilian researcher at Oxford University. “And then when Mandetta left, it became very clear that we would have no guidelines, no rules, no restrictions, or any sort of protective measure from the federal government.

“If you ask me for my key moments, they are all between February and April 2020,” he adds. “Everything else is just a consequence of decisions made - or not made - during these months.”

April: Mass burials in Manaus

Also in April Manaus, a sprawling city in the heart of the Amazon, gained notoriety as hospitals were overwhelmed and images of mass burials lapped the globe.

“Manaus was taken by surprise,” the city’s Archbishop, Leonardo Steiner, told the Telegraph last autumn. “There was this denial of the disease, [the government] just said ‘no it doesn’t exist’... Certainly we would have seen fewer deaths had the approach been different.”

Experts say the outbreak in Manaus should have been a wake-up call for the federal government, at a point when fear had already driven people to stay at home, regardless of official policy.

But disjointed decision-making continued. “We’ve never had a consistent and clear message coming from a position of authority, saying: this is what we know, this is what we don't know, this is your official guidance,” says Mr Schnekenberg.

Instead, Mr Bolsonaro pushed unproven treatments including hydroxychloroquine, joined anti-lockdown protests and declared “war” on state government leaders who adopted disease containment measures. When quizzed after the country's death toll first surpassed that in China, he simply replied: “I don't do miracles.”

This is one in a long list of controversial comments about the “little flu” from the President. “There’s no use trying to escape it, escape reality - we have to quit being a country of sissies,” he later said.

One tracking website, Aos Fatos, found Mr Bolsonaro has made more than 1,200 false or distorted statements about the pandemic since last March.

In an editorial in the British Medical Journal, three professors from the University of São Paulo - Deisy Ventura, Fernando Aith and Rossana Reis - called this a “a barrage of propaganda against public health”.

A summer of missed opportunities

Missed opportunities continued throughout the summer, says Prof Barberia.

The federal government’s landmark scheme offering monthly payments of 600 reais(£77) to 68 million Brazilians was popular, but to get hold the cash people had to queue in long lines outside Caixa bank - potentially spreading the virus.

President Bolsonaro promoted the handout as an economic stimulus, rather than a measure to allow people to stay at home like the UK’s furlough scheme. “So we saw this huge movement in cities and in local communities all over Brazil,” says Prof Barberia, as people were encouraged to shop and go back to work.

Then, as cases began to ease from June, state and municipal governments attempted to introduce tiered restrictions. While a good idea in theory, measures became confusing and frequently changed, leading much of the public to ignore them altogether.

Yet the biggest missed opportunity was securing vaccines, says Mr Schnekenberg. Not only has Mr Bolsonaro repeatedly questioned the safety of jabs - “if you turn into a crocodile, it’s your problem,” he quipped - but he has had a lackadaisical approach to securing supplies.

The country finally agreed a deal with Pfizer for 100 million doses last month. It is hoped these will boost Brazil’s stuttering vaccination campaign, which has so far been heavily reliant on Chinese jabs secured by Sao Paulo state’s governor.

“For a country the size of Brazil, it’s just absurd that we have contracts with so few vaccine manufacturers,” says Mr Schnekenberg. “Even if we could now vaccinate at the rate seen in the US, it still would take months to be able to see the effects. So in the short term, we're in a very difficult situation.”
January: Contagious new variant hits

But policy alone isn’t to blame for the current crisis: the virus has had surprises of its own.

In January a highly contagious new variant, known as P1, was detected in Manaus, as the hard-hit city experienced a second devastating wave of infections. By February the city’s health system was once again on the brink, a surprise to many who believed the size of Manaus’ first outbreak would trigger some protection from a second.

Prof Barberia says Brazil failed to “learn from what happened in the UK”, where the Kent variant triggered a major surge from late 2020.

“P1 could have been an opportunity for a really concerted effort to call a national coordinated response,” she says. “Instead I think we've really lost momentum.

“Testing and surveillance remains limited, and we allowed P1 to spread throughout Brazil without reacting. In hindsight, we even helped it’s spread - at least 15 states received Covid patients from Manaus,” she adds.
What next?

Experts say Brazil’s biggest problem has been believing that prevention wasn’t necessary, that they could treat their way out of the pandemic - care for the sick and let everyone else carry on as normal.

That was a mistake, says Prof Barberia, but with President Bolsonaro’s continued emphasis on the economy - and his insistence that state governors who introduce restrictions are “tyrants” - the approach doesn’t look set to change.

With a highly volatile political situation and a slow vaccination drive - only around seven per cent of the population have had a jab so far - most experts agree the country is in for a rough few months.

“We don't have stability in terms of ministers, and it's not very clear where we are at this moment with the armed forces, so we’re at a very difficult moment,” says Prof Barberia. “I’m very worried.”

“Honestly, I don’t know, but I can’t see it ending well,” adds Mr Schnekenberg. “I think we’re still going to see very high levels of mortality for quite some time.”

‘Like Boris Johnson Telling Steve Jobs How To Design The iPhone’: Experts Urge Overhaul Of U.K. Energy Market

Climate research, renewables and circularity



We're producing and using electricity in new and smarter ways, but is the way the government ... [+] GETTY

The U.K. must overhaul its entire electricity market if consumers, the economy and the climate are to benefit from new innovations in green energy such as smart homes, electric vehicles and heat pumps, a new report has concluded.


While the way Britain produces its electricity is unrecognizable from 10 years ago, with renewables such as wind and solar power helping the country to get halfway to its net zero emissions target, the outdated way the government awards contracts is preventing consumers from feeling the full benefits of a decarbonized grid, and holding back efforts to achieve grid flexibility, the report contends.

Instead, says Energy Systems Catapult, the U.K. non-profit energy and tech center which authored the report, the government should give innovative energy and tech companies the ability to drive the push to net-zero carbon emissions by decentralizing its process of contracting energy providers.


“The current government-directed approach to energy is like Boris Johnson telling Steve Jobs how to design the iPhone,” said Guy Newey, strategy and performance director at Energy Systems Catapult. “The progress on renewables over the past 10 years has been extraordinary, but if we are to finish the job of decarbonising the power sector—and create new businesses and jobs—we need to unleash the potential of our brilliant digital energy innovators to create a more flexible and greener system.”

The Catapult recommends six major changes to the U.K.’s electricity market, including a demand for more accurate, real time electricity pricing, and an obligation for sellers to source ever more low carbon energy. The report also calls for investment mechanisms such as the government’s Contracts for Difference—a form of subsidy—to be phased out, making the argument that such mechanisms were designed for a far less mature market, where the business case for renewable energy was not yet proven. The Catapult argues that these should be replaced with “outcome-based” policy mandates.

Opening the market up in this way, the authors say, will enable consumers to take full advantage of new technologies such as battery storage, heat pumps and electric vehicles, and help maximize the effectiveness of digitization, whereby home heating and other services can be controlled from the customer’s smartphone, offering greater comfort and potentially lower bills.

The Catapult says the reforms would also help facilitate “energy as a service” business models, which bundle together low-carbon energy supply with low-carbon technologies such as heat pumps or solar panels and batteries, much like a payment plan from a mobile phone network.

“What’s needed is an aggressive evolution of the energy market,” Newey told Forbes.com. “You need a set of market signals that reflect the physics of a system where supply varies.”

Until recently, Newey explained, the relationship between people and electricity providers was entirely one-way, with energy flowing from generators to consumers. But with digitization, he said, energy consumption could now be controlled and stored flexibly, improving efficiency and reducing costs.

“These new innovations will benefit from our reform proposals because electricity markets will more accurately put a value on products and services that can utilise and store energy when it is cheap and plentiful, delivering a cost saving to the energy system,” he added.

Needless to say, firms in the energy sector have welcomed the proposals. Caroline Bragg, head of policy for the Association for Decentralised Energy, an industry body that represents a large number of energy services firms, said: “The center of gravity of the energy system is well and truly on the move—shifting from large generation and supply to energy users from industry, offices to our homes … This very timely report sets out how we can unleash the vast, hardly tapped potential of innovative offerings across zero carbon heat, flexibility and energy efficiency.”

“This is just the sort of market reform we need to drive down costs as we go renewable, to accelerate Britain’s green recovery and to make the U.K. the Silicon Valley of energy,” said Greg Jackson, CEO of Octopus Energy, a rapidly growing electricity supplier. “Adopting this approach we can make the green revolution faster and cheaper than anyone imagined. But we need to act now: neither the climate, nor citizens, should have to wait.”

For its part, the government in its recent Energy White Paper floated the possibility of energy market reform, while the U.K.’s influential Climate Change Committee in its Sixth Carbon Budget called for a “clear long-term strategy as soon as possible, and certainly before 2025, on market design for a fully decarbonised electricity system.”

In response to a Forbes.com request for comment on the report, a spokesperson for the government’s Department for Business, Energy & Industrial Strategy (BEIS) declined to say whether the Catapult’s recommendations would be taken into account in its reforms.

“As stated in our Energy White Paper, we are clear that we need to fully decarbonize electricity by 2050 as part of our commitment to building back better and greener from the coronavirus pandemic, and reaching our ambitious emissions targets,” the spokesperson said.

“It is the government’s job to create the right market conditions to deliver on that objective, encouraging competition to empower industry to find low cost routes to net zero. This is why we committed to a £1 billion net zero innovation portfolio in the Prime Minister’s Ten Point Plan—including £100 million for energy storage and flexibility—to help create the market competitors of tomorrow,” they added.

U.S. FDA approves 2 at-home rapid COVID-19 tests. When will Canada catch up?
Hannah Jackson

Pressure is mounting for the Canadian government to authorize COVID-19 rapid tests to be used at home as more have been approved for use in the United States.

Earlier this week, the U.S. Food And Drug Administration (FDA) authorized two more over-the-counter COVID-19 tests that can be used at home to get rapid results.

The FDA said Abbott’s BinaxNow and Quidel’s QuickVue tests can now be sold in the country without a prescription.

The tests allow users to collect a sample at home, with a nasal swab that is inserted into a test strip. The results are usually ready within 10 to 20 minutes.

Dr. Michael Mina of Harvard told The Associated Press that the expanded testing options would be critical as new virus variants spread and researchers study how long protection from vaccines lasts.

“Vaccines are incredibly important but they are not the end-all, be-all to this pandemic,” he told the outlet. “We need other tools in our arsenal and the widespread availability and rapid scale-up of tests for people to use in the privacy of their homes is going to be an extraordinary gain.”

How does Canada measure up?

To date, Health Canada has only authorized the sale and use of COVID-19 tests administered by health professionals or trained operators.

In an email to Global News on Saturday, a spokesperson for Health Canada said the agency "is aware of the approval of the COVID-19 tests" in the United States.

"It is important to recognize that Canada's context is different from the U.S.," the email read.

The agency did not expand on how exactly the context differs.

To date, 63 tests to identify the novel coronavirus have been approved by the Canadian agency. Of those, 15 point-of-care or 'rapid tests' devices have been authorized for use.

Those tests, however, still require a health professional or trained personnel to administer.

However, the agency's website says it is "open to reviewing all testing solutions."

"This includes approaches that use self-testing kits, to enable individuals with or without symptoms to assess and monitor their own infection status."

Health Canada requires rapid tests to meet a minimum standard of 80 per cent sensitivity or accuracy before their application can be approved.

However, the federal government is allowing people who enter into the country at some land border crossings to administer their own test, in an effort to limit the amount of professionals needed.

Those samples are then sent to a lab for processing.

In a series of tweets Sunday morning, Kashif Pirzada, an emergency physician in Toronto, said "rapid tests need to be used ASAP to get workplace outbreaks under control."

"Many are sitting unused in warehouses across the country," he wrote. "You can combine the rapid strips (like Abbott Panbio) with much more accurate molecular tests onsite to recheck positive results (Abbott IDNOW)."


He said this, combined with "better masks, vaccinations, improved sick leave, will go a long way to get the situation under control."

The total number of COVID-19 infections in Canada topped one million on Saturday, as cases of the new, more transmissible variants continue to climb.

Several provinces, including Ontario and Quebec, have imposed more stringent measures in a bid to stem the spread of the virus, while officials work tirelessly to vaccinate the population.

Advocates have, for months, been urging Health Canada to approve over-the-counter rapid tests for use in Canada, saying they are key to identifying asymptomatic cases and would help alleviate lab backlog.

In a previous interview with Global News, Colin Furness, an infection control epidemiologist and assistant professor at the University of Toronto, said while the rapid tests approved by Health Canada are useful, at-home screening tests could be even more so.

He said this type of screening test would be “enormously useful” in helping to alleviate the backlog of tests in Canada’s laboratories and would allow businesses and schools to remain open more safely.

He said they should be utilized not as a diagnostic test, but rather a "screening tool."

"It should be seen a little bit like taking your temperature at home," he explained, adding that anyone who receives a positive result would then follow up with a lab test to confirm the results.

According to the Health Canada website, the agency is receiving a "very high volume of requests for authorization."

It was not immediately clear, though, how many of those applications were for rapid, at-home, or 'over-the-counter' COVID-19 tests.

US Federal government sued as monarch butterfly, spotted owl await protection decisions

The Biden administration is continuing to field lawsuits filed over Endangered Species Act decisions made by the Trump administration.

The Center for Biological Diversity sued the U.S. Fish and Wildlife Service Thursday over its failure to provide protections under the Endangered Species Act for 10 species "it admitted needed them," according to the organization.

MORE: Fate of monarch butterfly still hangs in the balance after endangered species decision

Among the species are the monarch butterfly, which in December the Trump administration decided that adding it to the list of threatened species was "warranted but precluded." This meant that while the monarch butterfly became a candidate for listing as an endangered species, it was not yet listed as the agency prioritizes other candidates.

The monarch butterfly was added to the International Union for Conservation of Nature's Red List of Threatened Species in 2014 after it was determined that 90% of its population had declined from its original levels. While millions of the butterflies spent winters in the coastal groves of California in the 1980s, just 30,000 were counted in 2019

Other species that the lawsuit describe as being left in "regulatory purgatory" are the northern spotted owl, which was found in December to warrant an uplisting from threatened to endangered, and the Eastern gopher tortoise, which has been awaiting protections since 1982

Northern spotted owl populations have continued to decline in the face of continued loss of old forests to logging and invasion of its habitat by barred owls, while the gopher tortoise, which need large, un-fragmented, long-leaf pine forests to survive, are severely threatened by development, which caused habitat loss and fragmentation.This limits food availability and options for burrow sites and exposes them to being crushed in their burrows during construction, run over by cars or shot, according to the Center for Biological Diversity

There have been a number of additional lawsuits brought against the federal government since Biden took office.

Multiple conservation groups sued the USFWS on March 25 over a decision by the Trump administration to deny the north Oregon coast population of red tree voles protection under the Endangered Species Act. Red tree vole populations have been devastated by logging, wildfires and inadequate protections on state and private lands. The USFWS found the vole warranted protection in 2011 but deemed that the protection was precluded by listing other species. The vole was then denied protections in 2019.

The Center sued the USFWS on March 25 to challenge the Trump administration's downlisting of the American burying beetle from endangered to threatened. The lawsuit requested that the endangered status be reinstated as the beetle continues to face threats from climate change and habitat destruction that are pushing it to the brink of extinction. The delisting came following the petition by the Independent Petroleum Association of America to delist the species, according to the Center.

Multiple conservation groups sued the USFWS on March 24 for refusing to designate critical habitat for the highly endangered rusty patched bumblebee. The USFWS stated in September that listing was "not prudent" because the availability of habitat does not limit the bee's conservation. The bumblebee was protected in 2017, but the USFWS failed to designate critical habitat by the statutory deadline.

The Center sued the USFWS on March 3 for failing to designate critical habitat and develop a recovery plan for Hawaii's threatened 'i'iwi, or "honeycreeper" bird. The USFWS listed the species as threatened in 2017.

On Wednesday, the Center also filed a notice of intent to sue the National Marine Fisheries Service to make a decision on whether the Oregon coast spring-run chinook salmon warrants protection. Chinook salmon once thrived in all of Oregon's coastal watersheds but have largely disappeared due to logging, roads and other sources of habitat degradation, such as dams and poorly run hatcheries, according to the Center. The decision has been overdue since September.

On Feb. 4 the Biden administration responded to a lawsuit filed by multiple conservation groups on Jan. 19 -- one day before Inauguration Day -- by delaying a rule finalized in the last weeks of Donald Trump's presidency to eliminate long-standing, vital protections for more than 1,000 species of waterfowl, raptors and songbirds. The decision was made over a reinterpretation of the Migratory Bird Treaty Act.MORE: Animal conservation groups to sue federal government over dwindling giraffe population

Only 25 species were give protections under the ESA during Trump's four years in office, according to the Center.

In 2019, the Trump administration made changes to how the government handles endangered species, altering the requirements for how the government decides to add or remove species from the list of endangered animals that are regulated by the government, including limiting how much habitat must be protected.

The changes require separate plans for protecting any new species listed as threatened instead of granting them the same protections as those listed as endangered, a move that advocates say could make it more difficult to protect species that are threatened by human activity and climate change.MORE: How advocates say Trump's endangered species rules could threaten conservation

"The past four years were a dark period for endangered wildlife and the environment overall," Noah Greenwald, endangered species director at the Center for Biological Diversity, said in a statement Thursday. "We're bringing this lawsuit to ensure these 10 species that so desperately need help are prioritized by the Biden administration, which has its work cut out for it to undo the incredible harm done under Trump."

A representative for USFWS declined to comment.

Bonnie Rice, a representative for the Sierra Club Endangered Species said to ABC News in a statement that "The Trump administration's Fish and Wildlife Service made a major push to strip as many species as possible of endangered species protections" including other animals like the grey wolf.

Rice said the Sierra Club is challenging Trump's rollbacks, some of which will be legal challenges.

The Sierra Club "is committed to protecting 30 percent of lands and waters by 2030 to halt extinction and we're encouraged by the Biden administration's early work to act on climate and review endangered species rollbacks," Rice also said in the statement.

Trudeau’s military misconduct response highlights ‘pattern’ of ignoring complaints: Singh

Prime Minister Justin Trudeau's response to multiple allegations of high-level sexual misconduct in the Canadian military adds to a "pattern of behaviour" when it comes to ignoring red flags and complaints, says NDP Leader Jagmeet Singh.

In an interview with The West Block's Mercedes Stephenson, Singh said the government's lack of action in responding to the allegations about high-level appointees sends the message that women's complaints and safety are not being taken seriously.

"Right now, the message being sent is a woman came forward – women came forward in different cases – with complaints, they made it to the desk of the defence minister, and nothing was done. This falls directly at the feet of the prime minister," said Singh.

“So far, it looks like there’s a pattern of behaviour of ignoring sexual harassment or misconduct complaints – that women come forward, and nothing happens.”

“So far, the Liberal government’s sent the message they are not safe, and that’s wrong.”

Global News first reported allegations of inappropriate behaviour against Gen. Jonathan Vance on Feb. 2.

Days later, the military promised an independent review into misconduct within its ranks but shortly after that, Adm. Art McDonald stepped back from his role as chief of the defence staff following an allegation.

Multiple sources have told Global News the complaint is an allegation of sexual assault.

And last week, CBC News reported another senior military leader is facing an allegation of sexual assault.

READ MORE: Trudeau says he did not personally know of 2018 Vance allegation

Trudeau said last week he was never made aware of one of the allegations against Vance, which was shared with his defence minister, Harjit Sajjan, in 2018. Sajjan's chief of staff then shared it with Trudeau's office and the staff at the Privy Council Office -- the department supporting Trudeau's office -- have said they discussed the matter with officials in the Prime Minister's Office.

Vance was appointed by the previous Conservative government but got a pay raise and term extension under Trudeau, while both McDonald and Vice-Adm. Haydn Edmundson were promoted to their current senior roles under the Trudeau government.

The web of revelations has led to questions about why no one appears to have acted on the allegations sooner, and why none of the people paid to advise Trudeau appear to have told him anything about a serious allegation against a senior appointee.

It is not the first time the government's vetting and handling of allegations against senior appointee has come under scrutiny in recent months.

Former governor-general Julie Payette resigned in January following a scathing independent review into allegations of workplace bullying and abuse during her time at Rideau Hall.

Trudeau abandoned the use of an advisory panel normally used to select governors-general when he appointed Payette, a former astronaut and scientist. And his government appears not to have checked with several of Payette's former employers about her workplace conduct.

CBC News has reported that Payette faced workplace conduct complaints dating back to the 1990s, and stemming from her time at the Canadian Space Agency, the Montreal Science Centre, and the Canadian Olympic Committee, including two internal investigations into her behaviour.

Trudeau has defended the vetting done on Payette, saying all procedures were followed but said in January that the government would look at what could be done to improve vetting of appointees.

Adios to Edmonton's Spanish-style apartment block and the unique community it fostered

I NEVER HAD THE PLEASURE TO LIVE IN THE MIRADOR, BUT HAD FRIENDS THAT DID

I LIVED IN A DIFFERENT SELF CREATED COOP APARTMENT BLDG WITH A SIMILAR SOCIAL ECOLOGY IN THE EIGHTIES; BALFOUR PLACE ON 116ST.

© Jamie McCannel/CBC El Mirador Apartments is one of the residential and commercial buildings near the intersection of 108th Street and Jasper Avenue that is being demolished for an incoming development.

Gatherings in the cherished courtyard of Edmonton's El Mirador Apartments are coming to an end after residents were told they have to move out by June 30.

The El Mirador is among the buildings being demolished at 108th Street and Jasper Avenue to make way for a commercial and residential development at the intersection's northeast corner.

With its white stucco walls, spiralling staircases and balconies, the wrecking ball won't just sweep away Edmonton's only known piece of Spanish Revival architecture. It will also demolish a unique building design that has fostered a sense of community for decades.

"A lot of the tenants became our roommates and the courtyard is our living room and our party room," said Charlie May, who has lived at El Mirador for the past 16 years.

"Every night after work, people would come out here and we'd all get together, sometimes 15, 20 people even, and we'd stay out till it got dark. Just chatting, having a few beers," he told CBC News this week.

"Sometimes when people move out, we'd have big going-away parties —and I mean big parties, lots of fun. The most amazing wedding that I'd ever attended took place here. And the porches were full of people. The courtyard was full of people."

The interior is just as impressive, with its original glass doorknobs, old fireplaces and hardwood floors.

'It's a beautiful building and it had a real heart. But now that's gone," May said. "It's very, very sad."

Community by design

According to the Edmonton Historical Board, the El Mirador was built in stages. Its core was a wood-framed house built in 1912 which in 1935 saw the addition of a 12-unit apartment building on the home's front. Another addition, in 1937, was a U-shaped building that created the building's distinctive courtyard.

El Mirador is not the kind of architecture typically found in Alberta, but rather is of a flavour more common in southern California, the historical board says on its website.

Unlike some building courtyards that sit unused, the design of El Mirador means tenants have to walk through the courtyard to get to their apartments.

News of the demolition has put a damper on residents' annual spring ritual of buying flowers and sprucing up the courtyard to usher in another summer of making memories.

Phillip Thomarat recalled years of parties and potlucks, Christmas dinners and Taco Tuesdays at the apartment that has been home for the past 18 years.

Former residents still turn up for festivities — and many are expected to attend the final going-away bash.

"It is kind of like living in a goldfish bowl because everybody's doors faces onto the courtyard," Thomarat said.

But that helped foster the sense of community spirit, he said.

"Neighbours have always helped out. We've always made lots of friends. It's just a great community."

The incoming project by Pangman Development Corporation will see a mid-rise building connecting 35- and 45-storey towers that stretch up into the skyline. It's a development that aims to revitalize the area with hundreds of rental and condominium units as well as street-level retail space.

"We're getting ready to start construction this summer," Pangman told CBC on Thursday. "We wanted to give tenants at least 90 days to find a new home."

Thomarat is pretty sure he won't find another home like El Mirador.

"In Edmonton, we have a lot of beautiful new buildings but this is something totally unique that I think should have been kept if possible," said Thomarat.

"It's a really good design for keeping people together and creating a community."
