'Teachers’ union ‘double-dog dares’ 

Trump to sit in class during pandemic

'There’s no one that wants their kids back with us more than teachers... but we want to open it safely'

Louise Hall The Independent JULY 9, 2020

The president of the largest US teachers union has said they “double-dog dare” Donald Trump to sit in one of their classrooms during the pandemic when schools reopen.

Mr Trump has demanded that schools resume in-person classes in fall, and has also criticised the Centre for Disease Control’s (CDC) guidelines for re-opening as “expensive” and “tough”.

“There’s no one that wants their kids back with us more than teachers... but we want to open it safely,” National Education Association (NEA) President Lily Eskelsen García told CNN on Wednesday.

“We see what happens when they let bars open prematurely,” she added, referencing a number of states that have seen a surge in cases after re-opening their economies early on.

“This isn’t a bar. We’re talking about second graders. I had 39 sixth graders one year in my class. I double-dog dare Donald Trump to sit in a class of 39 sixth graders and breathe that air without any preparation for how we’re going to bring our kids back safely,” she said.

White House kicks off push to open schools despite Covid-19 surge

The NEA has insisted on a number of benchmarks before schools can re-open safely including personal protective equipment, deep-cleaning procedures that meet CDC standards, classroom layouts allowing six feet of distancing alongside hand-washing and sanitising stations.

On Wednesday, Mr Trump threatened to cut federal funding for districts ignoring his demand after suggesting that strict guidelines could lead some officials to decide to continue teaching an online-only curriculum by fall.

“In Germany, Denmark, Norway, Sweden and many other countries, SCHOOLS ARE OPEN WITH NO PROBLEMS,” Mr Trump wrote on Twitter. “The Dems think it would be bad for them politically if US schools open before the November Election, but is important for the children & families. May cut off funding if not open!”

The president has made it clear that he disapproves of the CDC’s new guidelines which aim to keep children safe through social distancing, cloth face coverings, the closing of communal areas like dining rooms and playgrounds, and possible implementation of hygienic barriers.

“I disagree with @CDCgov on their very tough & expensive guidelines for opening schools. While they want them open, they are asking schools to do very impractical things. I will be meeting with them!!!” he tweeted on Wednesday morning.

Ms Garcia suggested that the “expensive” measures should be funded with the $3 trillion HEROES Act passed by house democrats in May that has not yet been considered by the Republican-controlled Senate.

The US has over three million confirmed cases of the novel coronavirus and has seen 132,723 deaths as of Thursday, according to data from the Johns Hopkins University.

The arts are an essential service – as vital as health, education, defence

CUT THE WAR BUDGET FUND THE ARTS

The Tories’ cash injection is not before time, says Mark Hudson, but it’s still a box of band-aids rather than a life-saving transfusion

The National Gallery allowed its first visitors on Saturday ( EPA )

The government’s announcement of a £1.57bn bailout for the culture sector is an acknowledgement – if somewhat belated – of the vital importance of the arts in our national life. “The beating heart of the nation,” boomed the prime minister. And if that’s hardly the subtlest of metaphors, for once Johnson got it essentially right.

There’s a tendency to think of theatres, art galleries and concert halls as optional luxuries in the wider struggle of life: frivolous add-ons that societies can afford to enjoy once they’ve paid for the really important things: health, education, infrastructure, defence. In fact, the arts, culture – whatever you want to call it – performs a vital function in our society, just as essential, in my opinion, as any of the so-called essential services we’ve been hearing so much about.

Indeed, while the past four months have left us feeling profoundly, and entire rightly, grateful to the NHS and the dedicated professionals who have risked – and in some cases given – their lives to keep the system going, this period has equally demonstrated the absolute centrality of the arts to the mental and physical health of the nation.

While we’ve been cooped up in our domiciles, deprived of life-giving social contact, put on furlough, losing our jobs and our loved ones, what have we actually been doing? While some have been driven frantic trying to homeschool children, while maintaining demanding jobs from the kitchen table, many more have been thrown back entirely on their own emotional resources. When final assessments are made, the Covid-19 pandemic and its lockdown will be found to have been as much a crisis in mental as physical health. And the things we’ve found to fill that terrifying spiritual and emotional gap – that sense of the abyss yawning beneath us – have been to a very large extent, and in the broadest sense, cultural.


Watching telly and posting years-old holiday snaps or listening to your favourite albums on Facebook may not be the most elevated of cultural pursuits, but they cater in varying ways to the imaginative and expressive impulse that is at the root of all art forms, and which can manifest itself in extremely destructive – as well as very positive – ways if not properly nurtured: from insanity, murder and suicide, to sexual abuse, drugs and alcohol addiction.

Covid-19 was a chance for the BBC to strip the Proms of its jingoism

The public has, in addition, been giving concerts via Zoom, often at an exemplary level, writing poetry (very much less exemplary, if my efforts were anything to go by), gardening, reorganising their photo archives, finishing novels, doing table-top art exercises set by famous artists. Many of the latter were piffling – I, for one, can’t wait to be rescued from Grayson Perry’s Art Club – but they show we just need to do this stuff. We’ve been on virtual gallery tours, seen great masterpieces locked away from the public gaze, with the feeling, certainly at the height of the lockdown when we were endlessly hearing that “things will never go back to the way they were”, that this was as close to a gallery visit as we would ever get again.


Now, with lockdown slowly lifting, the museums and galleries are among the first cultural institutions to open their doors – with the National Gallery allowing its first visitors last Saturday – and they’re opening onto a very different world to the one they closed them on in March. Blockbuster exhibitions, those resource-heavy mainstays of the big galleries will be in short supply in the stark and straitened post-Covid landscape, while more than 50 per cent of museum and gallery directors surveyed by the museum charity the Art Fund doubt the future viability of their institutions: from attracting visitors back to maintaining valuable collections.

Does new Barbican exhibition have important things to say about men?

These are grave questions. We’ve grown used to having culture on tap, as freely available as water or gas, and actually much cheaper to the consumer. The Victorians gave us our big national and municipal galleries, which are still free to enter. The post-war period gave us the Arts Council and all its works, while the late Nineties and early Noughties gave us a whole raft of spanking new, architecturally remarkable provincial galleries – Tate St Ives, Hepworth Wakefield, Margate’s Turner Contemporary – that have added immeasurably not only to the appeal of our towns and cities, but to the creative, cultural, social and, yes, economic vitality of the country.


The future of this great national resource is by no means guaranteed. The idea of museums and galleries going the way of pubs, banks and petrol stations as redundant chunks of real estate is horrible to contemplate.

Last autumn saw a £100m injection of government cash into the crumbling fabric of our national museums and galleries, a gesture that while very much welcomed was seen as more of a sticking plaster than a permanent remedy. In that context, the current £1.57m bailout, across the entire cultural sector – the breakdown of how it will be used has yet to be announced – feels more like a box of band-aids than a life-saving transfusion.

There are desperate times ahead for the cultural sector. Yet, on the question of attracting audiences back, I’m personally optimistic. After four months of online culture under effective house arrest, which has felt like a lifetime, people will be screaming to get back into real-life cultural spaces, with actual, physical works of art, where the injunction “please don’t touch the exhibits” will feel like a wonderful luxury. We need to support our museums and galleries, not just by giving donations and spending money in the cafe and shop, but by using them, making them ours, as their founders intended. It’s only when you’ve been deprived of the experience of being in a gallery or museum with other people, even if you don’t know them, speak to them or even look at them, that you realise what a precious, life-enhancing and essentially social experience that is.

Fast fashion books: Learn the truth behind brands like Boohoo


Garment workers in Leicester's factories have been found to be paid as little as £3.50 per hour and forced to work, even when they've shown signs of coronavirus, while conditions in other countries are terrifying. As consumers, it’s time to rethink and help bring about change

The affordability of clothing coupled with #ootd culture leads many of us to think we need a new outfit whenever we leave our homes. And when it comes to fast fashion, we all plead guilty to it one way or another – either by buying Zara’s polka dot dress last summer or copping Mango's Bottega Veneta inspired clutch bag.

The thrill we get after finding a cheap dress or dupe of a designer piece is undeniably problematic. And we needn’t look far to know that the price tag of many of our fashion buys frequently does not reflect the item's true cost.

The ethical and environmental issues surrounding the fashion industry are no secret and have been brought to light in the past few years, namely after the Rana Plaza garment factory collapse in Bangladesh in 2013. Around a third of the 3,122 workers died and the devastation also revealed the horrendous conditions many garment workers are forced to work in.

According to a recent McKinsey report, globally, people consume in excess of 100 billion pieces of clothing a year. And the textile industry is said to be the second biggest polluters, and responsible for 92 million tonnes of waste annually. Fast fashion is causing indisputable environmental implications, but the problems don’t stop there.

On a social level, garment workers remain mired in poverty because of the fast fashion business model to churn out fresh cheap lines of clothing at a frightening rate.

Take for example online retailer Boohoo. At the beginning of the coronavirus crisis, many brands grappled to make sense of how they would survive, Boohoo however seemed to have it nailed. Producing new lockdown inspired lines at lightning speed.

But a recent investigation has revealed the poor working condition in its Leicester based factories, with workers expected to be paid as little as £3.50 an hour, despite Britain’s minimum wage being £8.72 for those aged over 25.

Labour Behind the Label, garment workers’ rights group, made separate claims in its latest report – stating that those working in the Leicester-based factories that supply to the fast fashion giant were “forced to come into work while sick with Covid-19”.

This news comes after the Environmental Audit Committee (EAC) put forward several recommendations in its Fixing Fashion: Clothing consumption and sustainability report, which the government rejected. Points of note include the concerns of child labour, prison labour, and force labour.

Further afield, in countries such as Bangladesh and Cambodia, it is no secret that garment workers face unsafe conditions, with many brands turning a blind eye to the illegal subcontracting and allowing forced and unpaid overtime. And for there to be any meaningful change, the solution is rather simple, brands must pay garment workers a living wage – yet seem to continually ignore the calls for action.

What’s worse, when the pandemic hit, and spending nosedived, many brands faced changes in levels of demand, causing retailers – including Arcadia and New Look – to cancel orders to the tune of £2.5bn.

Bangladesh was hit hard by this. With garment manufacturing accounting for 84 per cent of the country’s overall exports, it left workers without an income and in destitution. In response, Lock Stock launched – a scheme bridging the gap between garment workers and wasted clothes. Delivering mystery boxes of clothes (costing £35) from a range of high-street brands for half the cost of the normal retail price.

While this was a positive move at a time when workers were under sheer desperation, this simply is not enough, and the fast fashion industry must wake up to its inequalities. This is not to say brands should relocate garment work, since countries rely heavily on it as a source of income. Instead, the big companies need to take more responsibility for change to happen.

As consumers, it’s time to rethink and help bring about change. Ways to do this include joining the #PayUp movement – a campaign demanding that brands pay for completed and in-progress orders, and support Fashion Revolution, Labour Behind The Label, and Fair Wear.

Coronavirus: Teachers need ‘urgent clarification’ before schools fully reopen, union says

NASUWT calls for ‘coordinated national plan’
Zoe Tidman THE INDEPENDENT JULY 7,2020

School attendance mandatory from September, Gavin Williamson says ( Clive Brunskill/Getty Images )

Teachers need “urgent clarification” over a range of issues for schools to safely reopen in September, a leading union has said.

The NASUWT teachers' union has asked the government for more information, including over how classroom teaching will carry on in the event of staff absences and what extra support will be available to help schools establish a safe return.

Their general secretary said “a significant number of measures” laid out in the guidance for a full reopening in September “require additional resources” in a letter to the education secretary, which urged the government to address the concerns of teachers and school leaders before all students are welcomed back in two months’ time.

“How schools will be able to fund these additional expectations is a key question we are being asked,” Dr Patrick Roach said in the letter to Gavin Williamson.

As well as mentioning extra funding, NASUWT said teachers and headteachers have also raised questions around protections for clinically vulnerable staff and extra cleaning provisions.

Dr Roach also urged Mr Williamson to address concerns over “the logistical challenge” of getting enough school transport so children from different year groups and schools would not have to mix.

He asked the education secretary to design a ”coordinated national plan” for the safe and full reopening of schools in September that addresses the ”many practical and logistical issues” teachers and headteachers have raised.

The Department for Education (DfE) said last week “detailed plans” have been released for schools and colleges in England to welcome back all students from September following disruption due to the coronavirus outbreak.

Certain year groups, including Year 1 and Year 6, were allowed back from the start of June.

Mr Williamson has said it will be “compulsory” for all pupils to go back to school in September.

Why Gavin Williamson can’t afford to mess up the reopening of schools

“The NASUWT recognises the importance of schools reopening to all children as soon as it is safe to do so,” Dr Roach, the general secretary, said.

“Schools have only a few weeks before they close for the summer break,” he added. “Teachers and headteachers need urgent clarification from the DfE if they are to be able to meet the guidance on September reopening consistently and safely.”
Dr Roach’s letter to the education secretary also called for clarity in the event of a confirmed case of Covid-19 in a school and to ensure the priority for coronavirus testing includes teachers.

DfE said last week guidance published ”provides schools, colleges and nurseries with the details needed to plan for a full return, as well as reassuring parents about what to expect for their children”.

The education secretary said: “The very best place for children to be is in the classroom, which is why we have set out our plans for all young people to return to education full-time from September.”

Mr Williamson added: “I want to reassure parents and families that we are doing everything we can to make sure schools are as safe as possible for children and staff, and will continue to work closely with the country’s best scientific and medical experts to ensure that is the case.”

Climate crisis: ‘Rising chance’ of temperatures exceeding 1.5C global target in near future

Met Office assessment for WMO reveals risk of breaching 1.5C mark has doubled since last major study

\

The planet is on course to break the 1.5C warming barrier in the next few years, according to the World Meteorological Organisation, only five years after the limit was agreed at the landmark 2015 Paris climate agreement.

The deal, to which almost every country in the world signed up, was to reduce greenhouse gas emissions sufficiently to keep global temperatures this century “well below” 2C of warming and to pursue efforts to limit the increase to 1.5C.

“In each of the coming five years (2020-2024) and there is a 20 per cent chance that it will exceed 1.5C in at least one year, according to new climate predictions,” the WMO has now said, adding that the 1.5C mark stood a 70 per cent chance of being exceeded during one or more months during the same time frame.

The last five-year period has been the warmest five years on record, and the global average temperature first surpassed 1C above what it was during the pre-industrial period in just 2015.

Temperatures around the world had been slowly falling for around 6,000 years before the impact of the industrial revolution reversed the trend in less than 150 years.

UK won't meet climate targets and the risks are ‘bigger than covid’

The new climate assessment, carried out by the UK’s Met Office on behalf of the WMO, is based on the expertise of internationally acclaimed climate scientists as well as the world’s best computer models, and provides a climate outlook for the next five years, updated annually.

The last such assessment suggested the short-term chance of hitting 1.5C of warming stood at 10 per cent. The new study doubles the risk.

WMO Secretary-General Petteri Taalas said: “This study shows – with a high level of scientific skill – the enormous challenge ahead in meeting the Paris Agreement on Climate Change target of keeping a global temperature rise this century well below 2 degrees Celsius above pre-industrial levels and to pursue efforts to limit the temperature increase even further to 1.5 degrees Celsius.”

The predictions take into account natural variations in weather and climate as well as human influences on the planet and other variables for the coming five years.

But the forecast models do not take into consideration the reductions in emissions of greenhouse gases due to the coronavirus lockdown.

“[The] WMO has repeatedly stressed that the industrial and economic slowdown from Covid-19 is not a substitute for sustained and coordinated climate action. Due to the very long lifetime of CO2 in the atmosphere, the impact of the drop in emissions this year is not expected to lead to a reduction of CO2 atmospheric concentrations which are driving global temperature increases,” said Professor Taalas.

“Whilst Covid-19 has caused a severe international health and economic crisis, failure to tackle climate change may threaten human well-being, ecosystems and economies for centuries.

“Governments should use the opportunity to embrace climate action as part of recovery programmes and ensure that we grow back better,” he said.

Professor Adam Scaife, the head of long-range prediction at the Met Office Hadley Centre said: “This is an exciting new scientific capability. As human-induced climate change grows, it is becoming even more important for governments and decision makers to understand the current climate risks on an annually-updated basis.”

Melania Trump statue set on fire in Slovenia

Comes after artwork of US president was destroyed in city east of Ljubljana earlier this year

IT IS SO UGLY I SUSPECT IT WAS BURNT DOWN BY MELANIA'S FAMILY MEMBERS WHO ARE STILL IN SLOVENIA
The Independent employs reporters around the world to bring you truly independent journalism. To support us, please consider a contribution.

A life-size wooden sculpture of Melania Trump has been damaged after being set on fire near her hometown in Slovenia on US Independence Day, the artist who commissioned the work has said.

Brad Downey, an American artist based in Berlin, had the charred sculpture of the US first lady removed on 5 July, a year after it was unveiled.

A police spokesperson told Reuters that the incident, which took place near the town of Sevnica, was being investigated.

The office of Ms Trump in Washington did not immediately respond to a request for comment.

Mr Downey, 39, said he had wanted the artwork to encourage a conversation about politics in the US, especially around Donald Trump’s anti-immigration policies and his wife’s status as an immigrant.
Speaking of those responsible for the fire, he said: “I want to know why they did it.”

The sculpture, which was carved from the trunk of a linden tree by a local folk artist before being erected in July 2019, does not bear a close resemblance to Ms Trump.

The unconventional work depicts her in a blue dress, similar to the one she wore to her husband’s inauguration in 2017.


Since Ms Trump became the US first lady, her home town has brought out a range of products, including wine and chocolate, named in her honour.

The destruction of the sculpture came as her husband pledged in recent weeks to take firm action against those who damage historical monuments in the US, following the toppling of statues at global anti-racism protests sparked by the death of George Floyd.

Earlier this year, a large wooden statue depicting the US president was burnt in Moravce, a city east of Slovenia’s capital Ljubljana.

A new look at deep-sea microbes

UD study looks at life inside and outside of seafloor hydrocarbon seeps

UNIVERSITY OF DELAWARE

Microbial cells are found in abundance in marine sediments beneath the ocean and make up a significant amount of the total microbial biomass on the planet. Microbes found deeper in the ocean, such as in hydrocarbon seeps, are usually believed to have slow population turnover rates and low amounts of available energy, where the further down a microbe is found, the less energy it has available.

A new study published out of a collaboration with the University of Delaware and ExxonMobil Research and Engineering shows that perhaps the microbial communities found deeper in the seafloor sediments in and around hydrocarbon seepage sites have more energy available and higher population turnover rates than previously thought.

Using sediment samples collected by ExxonMobil researchers, UD professor Jennifer Biddle and her lab group -- including Rui Zhao, a postdoctoral researcher who is the first author on the paper; Kristin Yoshimura, who received her doctorate from UD; and Glenn Christman, a bioinformatician -- worked on a study in collaboration with Zara Summers, an ExxonMobil microbiologist. The study, recently published in Scientific Reports, looks at how microbial dynamics are influenced by hydrocarbon seepage sites in the Gulf of Mexico.

Biddle and her lab members received the frozen sediments, collected during a research cruise, from ExxonMobil and then extracted the DNA and sequenced it at the Delaware Biotechnology Institute (DBI).

The samples Biddle's lab group studied were ones collected from deeper in hydrocarbon seeps that usually get ignored.

"Most people only look at the top couple of centimeters of sediment at a seep, but this was actually looking 10-15 centimeters down," said Biddle associate professor in the School of Marine Science and Policy in UD's College of Earth, Ocean and Environment. "We then compared seepage areas to non-seepage areas, and the environment looked really different."

Inside the seep, the microbes potentially lead a fast, less efficient life while outside the seep, the microbes lead a slower but more efficient life. This could be attributed to what energy sources are available to them in their environment.

"Understanding deep water seep microbial ecology is an important part of understanding hydrocarbon-centric communities," said Summers.

Biddle said that microbes are always limited by something in the environment, such as how right now during the quarantine, we are limited by the amount of available toilet paper. "Outside of the seep, microbes are likely limited by carbon, whereas inside the seep, microbes are limited by nitrogen," said Biddle.

While the microbes found inside the seep seem to be racing to make more nitrogen to keep up and grow with their fellow microbes, outside of the seep, the researchers found a balance of carbon and nitrogen, with nitrogen actually being used by the microbes as an energy source.

"Usually, we don't think of nitrogen as being used for energy. It's used to make molecules, but something that was striking for me was thinking about nitrogen as a significant energy source," said Biddle.
This difference between the microbes found inside the seeps and those found outside the seeps could potentially mirror how microbes behave higher in the water column.

Previous research of water column microbes shows that there are different types of microbes: those that are less efficient and lead a more competition-based lifestyle where they don't use every single molecule as well as they could and those that are really streamlined, don't waste anything and are super-efficient.

"It makes me wonder if the microbes that are living at these seeps are potentially wasteful and they're fast growing but they're less efficient and the organisms outside of the seeps are a very different organism where they're way more efficient and way more streamlined," said Biddle, whose team has put in a proposal to go back out to sea to investigate further. "We want to look at these dynamics to determine if it still holds true that there is fast, less efficient life inside the seep and then slower, way more efficient life outside of the seep."

In addition, Biddle said this research showed that the deeper sediments in the seepages are most likely heavily impacted by the material coming up from the bottom, which means that the seep could be supporting a larger amount of biomass than previously thought."We often think about a seep supporting life like tube worms and the things that are at the expression of the sediment, but the fact that this could go for meters below them really changes the total biomass that the seep is supporting," said Biddle. "One of the big implications for the seepage sites with regards to the influence of these fluids coming up is that we don't know how deep it goes in terms of how much it changes the impact of subsurface life."Summers added that these are interesting insights "when considering oil reservoir connectivity to, and influence on, hydrocarbon seeps."

Feeling with the heart 

Scientists find that the brain's sensitivity to sensory stimuli depends on the cardiac cycle and the brain's perception of it

NATIONAL RESEARCH UNIVERSITY HIGHER SCHOOL OF ECONOMICS  

A person's sensitivity to external stimuli depends not only on the state of their nervous system, but also on their cardiac cycle. Usually we do not notice our heartbeat, paying attention to it only in unusual situations, such as in moments of excitement before a performance or while experiencing arrhythmia. The brain actively suppresses the perception of our heartbeat, but as a result, our perception of other sensory stimuli may also be affected. This conclusion was made in a paper by a team of scientists from the Max Planck Institute for Human Cognitive and Brain Sciences (Leipzig) with the participation of Vadim Nikulin, a leading researcher at the Institute of Cognitive Neurosciences at HSE University.

A cardiac cycle consists of two phases: systole and diastole. During systole, the heart muscles contract, and during diastole, they relax. It has been suggested earlier that a person is more susceptible to various stimuli during diastole and less sensitive during systole.

To find out what happens to the brain during different phases of the cardiac cycle, the scientists conducted an experiment by stimulating the fingers of 37 subjects with a barely perceptible electrical current. After each test, participants were asked if they felt any stimulation. At the same time, their brain and heart activity was monitored with EEG and ECG, respectively.

As expected, during systole, participants often did not notice the presence of stimuli. A decrease in sensitivity was accompanied by a change in brain activity. EEG recordings can show the P300 potential associated with the detection of the stimuli. During systole, this potential was less pronounced. Interestingly, the amplitude of the pre-stimulus heart-beat evoked potential correlated negatively with the detection and localization of somatosensory stimuli. Thus, the greater the potential caused by the heartbeat, the lower the potential of P300, and the more likely the subject would not sense the current.

Researchers believe that the brain predicts when the next contraction of the heart will occur, and suppresses the perception of stimuli more strongly in the systole phase, so that we are not distracted by our heart rhythm or confuse it with an external stimulus.

'These results are interesting since they show that our conscious perception of the external world can change within every heartbeat cycle, which is a rhythmic event that we mostly don't pay attention to,' says Esra Al, the lead author of the study. 'Therefore, these findings suggest that not only the brain but also the body plays an important role in shaping our consciousness.'

The results of the study may provide new insight into the understanding of neuronal processes associated with anxiety conditions. Such conditions are associated not only with a change in the heart rate, but also with a change in one's perception of their heartbeat.

Aquaculture's role in nutrition in the COVID-19 era

New paper from American University and global working group ponders four likely scenarios

AMERICAN UNIVERSITY

 

Aquaculture,***  the relatively young but fast-growing industry of farming of fish and other marine life, now produces around half of all seafood consumed by humans. A new paper from American University published today examines the economics of an aquaculture industry of the future that is simultaneously environmentally sustainable and nutritious for the nearly 1 billion people worldwide who depend on it for health and livelihoods.

Of the scenarios the paper discusses, included are two approaches that illustrate what aquaculture might look like if nations refocus inward for food and nutrition security in the COVID-19 era.

"Seafood is essential to meeting global food and nutrition security goals," said Jessica Gephart, the paper's primary author and an assistant professor of environmental science at American University. "Under what circumstances, and with what policies, can we maximize aquaculture for its nutrition benefits and sustainability for all who rely on seafood?"

This is a challenging question to answer, especially in the COVID-19 era. As the pandemic is still unfolding, the full scope of long-term damage to food systems is unknown, the paper notes. Yet, the aquaculture industry is suffering major setbacks, as some exports are being halted, workers are being laid off, demand has dramatically decreased, production units are incurring large losses and some countries are reconsidering their reliance on foreign seafood. The authors note that such setbacks "can be particularly long-lasting for a budding sector, with many young farms that potentially lack the capital to weather the storm and the political clout to secure sufficient recovery aid."

The demand for seafood is expected to increase significantly by 2050, the paper notes, if historical trends in income and population growth, urbanization, and diets are maintained. This has prompted researchers to contemplate the future role of aquaculture in meeting demand and supporting nutrition needs. "Nutrition sensitivity" refers to the multiple benefits derived from diverse foods, including improving nutrition, valuing the social significance of food, and supporting livelihoods.

For aquaculture, this means a food system that supports public health through production of diverse seafood, provides multiple, rich sources of essential nutrients, and supports equitable access to nutritious, safe, and culturally acceptable diets that meet food preferences for all populations, without compromising ecosystem functions, other food systems, and livelihoods.

The paper describes and discusses four possible scenarios for the future of the growth of aquaculture, with the first two outlining what an inward approach might look like. Elements of each of these scenarios exist in current production systems from around the world:

Growth-first, nationalistic approach. In this scenario, countries throughout the world turn inward for economic growth and focus on supporting national industries to meet seafood demand. Overall, diversity of seafood available in each country generally declines. Countries with mature aquaculture sectors that already supply a diversity of production technologies, species and product types will continue to meet some nutritional needs, but for a narrower range of consumers and at increased cost, and to a more limited extent.

Sustainable growth, localized approach. In this approach, countries throughout the world adopt sustainable local food production approaches focused on small-holder production. While some traditional production systems are highly productive, in general, global aquaculture production grows at a relatively slow rate - if at all - and total production is relatively low. Countries that have retained a cultural history of developing small-scale aquaculture will see an increase in these production systems, supported by government-backed schemes and extension services. When production is at the household scale, women are more likely to play a key role, increasing the likelihood that nutritional benefits flow directly to the most vulnerable.

Sustainable growth, globalized world. The world fully embraces the application of sustainable development principles, taking advantage of the benefits of globalized food systems while strengthening environmental governance. Global competition and high levels of technology transfer lead to relatively high global inland and marine seafood production. Favoring production of seafood in line with local environmental contexts, this world leads to moderate global species diversity. High global seafood production and low trade barriers enable low seafood prices, improving seafood access in urban areas and areas with transportation infrastructure connections and access to electricity for refrigeration.

Growth first, globalized world. In this scenario, the world moves toward further economic globalization and encourages boundless economic growth. Through genetic selection and modification, as well as technological innovations, the aquaculture industry develops intensive production systems with limited environmental regulation. Production systems rely on globalized supply chains, sourcing feed ingredients internationally, and taking advantage of low labor costs for processing. Through competition, massive production of only a few species results, which are highly traded and spread rapidly (akin to the dominance of four species in the meat market, led by chicken). Targeted policy interventions would be necessary to help nutritionally vulnerable populations.

Researchers use a variety of modelling approaches to study form and function. By using a basic biomechanical model for studying body form and center of mass stability in ants, new research identifies the benefits of "simple models" and hope that it can be used for bio-inspired designs.

"Most organisms are constrained in their shape and size because they are juggling different needs such as the ability to fly, forage for food, and reproduce," said Andrew Suarez, a professor of entomology and the head of the Department of Evolution, Ecology, and Behavior at the University of Illinois at Urbana-Champaign.

"Ants are unique because they live in colonies and divide their responsibilities. Therefore, they don't have the body constraints that other insects do." "Ants have a wide range of head sizes relative to their body," said Philip Anderson, an assistant professor of evolution, ecology, and behavior. "Some ants have such extremely large heads that even though they look like their heads should pitch forward, they don't. To study their body design, I created a simple mathematical model to locate their center of balance."

The researchers, both affiliated with the Beckman Institute for Advanced Science and Technology, created a basic model of an ant body by treating it as a series of connected ellipsoids. They used ant body measurements from antweb.org, which has collections of ant pictures put together by the California Academy of Sciences.

The study "'Simple' biomechanical model for ants reveals how correlated evolution among body segments minimizes variation in center of mass as heads get larger" was published in Integrative and Comparative Biology.

"We found that the ants maintain a center of balance over where their legs are," Anderson said. "These models have helped us understand how these unusual forms of ants have evolved and how the rest of their body compensates for it."

"The worker ants are like hopeful monsters. They can play with their body form and produce more variation than other insects. With these models we can see that although they have these exaggerated forms, they are not breaking the laws of physics," Suarez said.

Even though the researchers have focused on simplifying the model as much as possible, there are some limitations "Treating the ant bodies like ellipsoids doesn't accurately represent their actual shape," Anderson said. "Additionally, I assume that every part of the body has the same density, but our co-author Michael Rivera has shown that the head is a lot denser than the abdomen, which changes the calculations."

The researchers are hopeful that such simple models can be used for applications that use bio-inspired designs. "What happens if you need to add weight to the front of a machine? Is it enough to add weight to the back or are there other ways to compensate? Using such models, we can look to nature for solutions to these issues," Suarez said.

The study was funded by the National Science Foundation.

The researchers took part in the symposium Melding Modeling and Morphology: integrating Approaches to Understand the Evolution of Form and Function at the Society for Integrative and Comparative Biology annual meeting this past January in Austin, Texas. Lindsay Waldrop and Jonathan Rader organized the symposium.
