The Norfolk Snout's horns are like the tusks of a warthog, said moth expert James Lowen

The discovery in a couple's garden of a moth believed extinct for more than 50 years has been described as "phenomenal" and of national importance.

The Norfolk Snout moth, first recorded near Norwich in Victorian times, was never seen anywhere else in the UK and then vanished after it was last spotted in the county in 1971.

The creature made its way into a light trap set by moth enthusiast Dave Jones - who has since found other Norfolks, whose snout he describes as a "bogbrush", breeding on a feed plant nearby.

"It's exciting that in a suburban garden in a small village you can capture a total rarity," said Mr Jones, of Stoke Holy Cross, near Norwich.

"Among all the other moths [in a light trap] there's always that chance you will get something unusual."

Mr Jones was puzzled by the brown-beige insect with 10mm-long wings while checking more than 200 moths he had trapped on a Monday night.

He assumed an identification app had got it wrong when it suggested a match for a moth listed as extinct.

"It's weird thing; it's so docile and it's got this snout that looks like a bog brush, and these amazing horns," said Mr Jones, who has set traps for 14 years and had previously found a Scottish grass moth , its second recording in England.

"I looked it up and I said to my wife Pauline, I think we've got a moth that's extinct," said Mr Jones, "it's not every day that happens."

He shared his photos to a WhatsApp group of Norfolk moth experts, who were excited and encouraging, and later that day it was verified by an authority on the species and released unharmed.

The caterpillar feeds on hoary mullein, a striking, metre-tall plant with yellow flowers which is known to grow in the south and west of Norwich.

"The following day I thought I would go and have a look [nearby], saw the plant and found them there," said Mr Jones.

"To find something in your trap is one thing, it is exciting, but I was more over-the-moon to find it on the plant and breeding - that was more of a buzz."

'Fantastically exciting'


Wildlife writer, photographer and lecturer James Lowen, who is in the WhatsApp group, said he suspected the moth had "gone off the radar" since its last sighting at a quarry in Snettisham, on The Wash.

"It's not much to look at, but when you look more closely its got a snout with these amazing horns on it, rather like the tusks of a warthog," he said.

"Its not just the back story that make it so unusual, but its appearance, too."BBC Springwatch: UK moth collection

He said general moth numbers appeared to be down this year, according to moth trappers, possibly due to the wet spring.

"It makes seeing this even more special," he added.

"It is very heartening but the overall balance sheet for moths is that we have lost 120 [species of] moths in the last 100 years.

"This is of national importance; it's phenomenal."

Diversity Action Plans for Clinical Trials: Evaluating FDA's Draft Guidance

— A critical analysis reveals opportunities and challenges prior to finalization

The FDA's initiative is not unlike the attempts of institutions of higher learning to increase student diversity through diversity, equity, and inclusion (DEI) programs.

The FDA is intent on improving the enrollment of participants -- also known as "subjects" -- from underrepresented populations in clinical studies for drugs and devices. The FDA's initiative is not unlike the attempts of institutions of higher learning to increase student diversity through diversity, equity, and inclusion (DEI) programs. The FDA has issued a draft guidance for sponsorsopens in a new tab or window -- mainly the pharmaceutical industry -- entitled "Diversity Action Plans [DAPs] to Improve Enrollment of Participants from Underrepresented Populations in Clinical Studies." After a formal commenting period set to end September 26, 2024opens in a new tab or window, the guidance will become official, pending revisions.

Clinical studies assess the safety and efficacy of drugs and devices designed for preventing, treating, or diagnosing various conditions and diseases. In the U.S., certain populations are often underrepresented in biomedical research despite bearing a disproportionate burden of specific conditions. This underrepresentation stems from multiple factors, such as assumptions about the feasibility of enrolling a representative population and the potential impact on study timelines, as well as the absence of a proactive strategy to ensure the enrollment and retention of a study population that mirrors the intended use population.

Toward Inclusivity

The FDA's draft guidance emphasizes the creation of DAPs aimed at ensuring the enrollment and retention of a clinically relevant study population that accurately represents various age groups, sexes, and racial and ethnic demographics. Nevertheless, the FDA acknowledges the wider issues of health disparities and unequal access to healthcare and clinical studies, which can be influenced by factors such as geographic location, gender identity, sexual orientation, socioeconomic status, physical and mental disabilities, pregnancy and lactation status, and comorbidities. The FDA encourages sponsors of clinical studies to consider these additional factors when developing their DAPs.

It should be noted that FDA guidance documents -- and there are many of themopens in a new tab or window on a range of topics -- describe the agency's current thinking on a topic and are to be viewed only as recommendations, unless specific regulatory or statutory requirements are cited.

The FDA's draft guidance on DAPs marks a significant advancement towards enhancing inclusivity and representation in clinical trials. The guidance provides a well-structured and detailed framework for sponsors to develop and implement DAPs. By specifying elements such as enrollment goals disaggregated by race, ethnicity, sex, and age, the FDA ensures that sponsors consider a wide range of demographic factors. This comprehensive approach is essential for addressing disparities in clinical research and ensuring that study results are applicable to diverse populations.

The guidance's suggestions for practical measures to reduce participant burden -- such as transportation assistance, dependent care, and flexible hours for study visits -- are particularly valuable. These recommendations can significantly enhance participation from underrepresented groups who may face logistical challenges in attending study visits.

Additionally, the encouragement of decentralized clinical trials (DCTs) is a forward-thinking approach. DCTs permit participants to complete parts or all of the clinical study at home, essentially bringing the clinical trial personnel and equipment to the participant rather than requiring participants to undergo evaluation at study sites. DCTs can increase accessibility for participants who are geographically distant from study sites, thereby enhancing the diversity of the study population. This aligns with the broader trend towards using technology to make clinical research more inclusive.

How to Improve the Draft Guidance

The draft guidance requires sponsors to monitor enrollment goals and provide updates in annual reports, which ensures ongoing accountability. This continuous oversight can help identify and address barriers to meeting diversity goals in real-time, potentially leading to more successful outcomes.

However, implementing the guidance may pose challenges, especially for smaller sponsors or those with limited resources. The additional administrative burden of developing, submitting, and regularly updating DAPs could be significant, and sponsors may need extra support and resources to comply effectively. Although the guidance is robust, some areas could benefit from greater clarity. For instance, the criteria for waivers from DAP requirements are outlined, but the process for obtaining such waivers might be further detailed to prevent ambiguity. Including more specific examples or case studies could also help sponsors understand how to meet enrollment goals effectively.

Implementing the recommended measures, such as providing transportation assistance and dependent care, could increase the costs of conducting clinical trials. While these measures are essential for improving diversity, they may also impact the overall budget and feasibility of clinical studies, particularly for smaller companies. Moreover, the guidance emphasizes the importance of monitoring enrollment goals but is less clear on the enforcement mechanisms if sponsors fail to meet these goals (probably because FDA guidance documents are not binding). More stringent enforcement policies or incentives for compliance could strengthen the effectiveness of the DAP requirements.

The Impact of More Diverse Study Populations

By promoting the inclusion of diverse populations in clinical trials, the guidance can enhance the generalizability of study results. This is crucial for ensuring that medical products are safe and effective for all segments of the population, not just those historically overrepresented in clinical research. Increased transparency and efforts to include underrepresented populations can improve public trust in the clinical research process, which is particularly important given the historical mistrust among certain demographic groups towards medical research (think: Tuskegee Syphilis Study)opens in a new tab or window.

The emphasis on DCTs and reducing participant burden could drive innovation in clinical trial design and execution. Sponsors may develop new strategies and technologies to meet these requirements, potentially leading to more efficient and inclusive clinical research practices.

In conclusion, the FDA's draft guidance on DAP represents a significant and necessary step forward in promoting inclusivity in clinical research. While comprehensive and well-intentioned, its implementation may pose challenges, particularly for smaller sponsors. Enhancements in clarity, support for implementation, and enforcement mechanisms could further strengthen its impact. Overall, the guidance has the potential to significantly improve the representation of diverse populations in clinical trials, thereby enhancing the generalizability and applicability of medical research outcomes.

Abstract

Active sensing is a behavioral strategy for exploring the environment. In this study, we show that contact vocal behaviors can be an active sensing mechanism that uses sampling to gain information about the social environment, in particular, the vocal behavior of others. With a focus on the real-time vocal interactions of marmoset monkeys, we contrast active sampling to a vocal accommodation framework in which vocalizations are adjusted simply to maximize responses. We conduct simulations of a vocal accommodation and an active sampling policy and compare them with actual vocal interaction data. Our findings support active sampling as the best model for real-time marmoset monkey vocal exchanges. In some cases, the active sampling model was even able to partially predict the distribution of vocal durations for individuals to approximate the optimal call duration. These results suggest a non-traditional function for primate vocal interactions in which they are used by animals to seek information about their social environments.


Introduction


Contact calls are produced by a variety of animals, particularly when they are out of sight of one another. The functions of contact calls seem to be context-dependent. Among primate species, the same vocalizations are variously used during territorial encounters, mate attraction and isolation1. In all contexts, contact calls produced by one individual typically elicit a similar vocalization by another. There are two common assumptions as to the immediate purpose of these vocal exchanges. The first is that the goal of each individual is to maximize the probability of a response from the other (e.g., frogs2,3 and monkeys4,5). The second assumption is that, in some cases, vocal plasticity is used to either adjust these vocalizations acoustically to signal social closeness or to optimize signal transmission in noisy environments. This, again, has the purpose of increasing the probability of a vocal response (a phenomenon known as “vocal accommodation”6). Here, we consider another possibility: vocal exchanges are a form of active sensing used to gain information about conspecifics (that is, they are active sampling)7, information that can be used to estimate the probability of response. By active sensing, we mean the purposive use of motor control to emit a self-generated energetic signal to collect sensory information8. Active sampling, on the other hand, is defined as defined as gathering information that is important for a specific task7.

Marmoset monkeys are one species where there has been much focus on the use of their contact calls in vocal exchanges (Fig. 1). When by themselves, adult marmosets will produce contact calls and will do so approximately every 10 s as a function of an autonomic nervous system rhythm9,10. When auditory contact is made, two marmosets will communicate with multiple back-and-forth exchanges of contact calls10. When the distance between them changes or if they become visible to each other, then marmosets adjust the latency, loudness, and/or duration of their contact calls and/or switch to producing different affiliative call types11,12. These and other data demonstrate that marmoset vocal production remains flexible (or plastic) throughout adulthood13,14,15. Here, we test whether the real-time contact calling behavior of marmoset monkeys is consistent with active sampling. Are they interrogating their social environment using a “question-and-answer” strategy?

One proposal for active sampling suggests that animals in complex environments with incomplete information use a belief-based policy16, where “belief” here means the state of an animal’s knowledge at that moment. In a belief-based system, information has value, and this value can motivate exploration under conditions in which they must consider many alternatives and where the potential rewards are not known beforehand. In the context of contact calling by marmoset monkeys who, under natural conditions, live in dense, tropical rainforests where they cannot easily see conspecifics, we hypothesize that vocalizing is a way of seeking information about conspecifics.

In ShortHindus for America First group endorses Trump in upcoming polls
Claims Kamala Harris would destabilise India-US ties
Raises concern about Hindu persecution


Hindus for America First, a newly created grassroots organisation, has announced it will endorse Republican presidential candidate Donald Trump and launch a campaign against Democratic nominee Vice President Kamala Harris in the key battleground states of Pennsylvania, Georgia and North Carolina.

Announcing the decision on Thursday, Hindus for America First chairman and founder Utsav Sanduja claimed that Harris would be "very destabilising for Indo-US relations".

"The concern is that if Kamala becomes the president of the United States, then she might put in some liberal wolves on the bench who may actually reverse the Supreme Court on this (and) that impacting the Asian-American voters," he said.


The Biden-Harris administration has not kept the border secure. Harris is the second in command after President Joe Biden and did nothing to stem the flow of illegal immigrants into the US, he said.

"As a consequence of all these illegal immigrants, we've seen record crime, record drug smuggling... and it ends up affecting minority communities, in particular many of the Asian-American business owners," he said.

On the other hand, Sanduja praised Trump's efforts to make the immigration system more merit-based. He also lauded the former president's efforts to bolster defence and technology cooperation with India.

Trump is "very pro-India". He was able to cultivate an excellent relationship with Prime Minister Narendra Modi and collaborate on many defence projects that would enable India to take on China, he said.

Unlike Harris, who made a lot of "disparaging remarks" about the government and people of India, Trump did not interfere in the country's internal affairs, Sanduja said.

"Kamala Harris would be very destabilising for Indo-US relations," he claimed.

He said Hindus for America First is organising efforts among Hindus in battleground states like Georgia, North Carolina, Pennsylvania, Michigan, Wisconsin, Arizona, and Nevada against Harris.

Sanduja said the global Hindu community is concerned about the attacks on Hindus in Bangladesh.

"We would request all political entities concerned to raise this issue," he said, adding that the Hindus of Bangladesh are suffering.

"I give President Trump a lot of credit. Under his leadership, the State Department acknowledged the persecution of Hindus in various parts of the subcontinent, like in Afghanistan...Pakistan, it was President Trump that took the leadership in acknowledging Hindu genocide," he said.

GOP OFFICIALLY DEAD

Former Vice-President Dick Cheney to vote for Kamala Harris


Michael Sheils McNamee
BBC News
BBC

Former US Vice-President and lifelong Republican Dick Cheney has confirmed he will vote for the Democrats' Kamala Harris in November's presidential election.

Mr Cheney, seen as an influential figure during the presidency of George W Bush, issued a statement saying there had "never been an individual who is a greater threat to our republic than Donald Trump", the current Republican candidate.

His daughter, former Republican lawmaker Liz Cheney, had told an audience in Texas earlier that her father planned to back the Democratic nominee.

“He [Trump] tried to steal the last election using lies and violence to keep himself in power after the voters had rejected him," said Mr Cheney. "He can never be trusted with power again."

“As citizens, we each have a duty to put country above partisanship to defend our constitution," he added. "That is why I will be casting my vote for Vice-President Kamala Harris.”

Mr Cheney's remarks were welcomed by the Harris camp.

“The vice-president is proud to have the support of Vice-President Cheney, and deeply respects his courage to put country over party,” said campaign chair Jen O’Malley Dillon.

Mr Cheney joins a growing list of Republicans who have expressed concern about the candidacy of Donald Trump.

His daughter, Liz Cheney, has already given her backing to Vice-President Harris.

She served on the House select committee investigating the 6 January Capitol riots, and was one of 10 Republicans to vote to impeach former President Trump after the incident.

Ms Cheney lost her seat in Congress in 2022 to a Trump-backed candidate.

Taking to social media following Mr Cheney's statement, Trump called the former vice-president an "irrelevant RINO" - an acronym which stands for "Republican in name only".

He also described Mr Cheney as the "King of Endless, Nonsensical Wars" - alluding to his role in the Iraq War.  


Who is Dick Cheney and why is he supporting Kamala Harris? Explained

Ex-Republican Vice President launched a stinging attack on Donald Trump as he backed the Democrat presidential candidate

iNEWS
September 7, 2024 

Former Republican Vice President Dick Cheney has announced he will be supporting Democrat candidate Kamala Harris rather than Donald Trump in November’s US election.

Trump, the Republican nominee, and Ms Harris are locked in a tight race for the White House and will face off in a crunch live TV debate next week.

Some Republicans who are upset with Trump’s control over the GOP and his actions have recently thrown support behind Harris, including dozens of former staffers of former Presidents George HW Bush and George W Bush, the latter whom Mr Cheney served as Vice President.

Who is Dick Cheney?

Dick Cheney served as vice president under Republican President George W Bush from 2001 till 2009.

The 83-year-old has made few if any public appearances over the past year or more but has dealt with heart issues since his 40s and underwent a heart transplant in 2012.

He has faced criticism over the years from human rights groups as he played a large role in planning the US wars in Afghanistan and Iraq, which produced a heavy civilian death toll and human rights abuses.

In the case of Iraq, the war was based on claims that Saddam Hussein’s government had weapons of mass destruction – and proof of this claim was never found.

His daughter, Liz Cheney, lawyer and former congresswoman, has previously endorsed Ms Harris.

Both Liz and Dick Cheney have been outspoken critics of former President Donald Trump, notably during the former’s failed re-election campaign in 2022.
Why is Cheney supporting Harris?

Mr Cheney put out a statement confirming his endorsement, which read almost entirely as opposition to Trump rather than support of Harris.

He said “in our nation’s 248-year history, there has never been an individual who is a greater threat to our republic than Donald Trump.”

Mr Cheney continued: “He can never be trusted with power again.

“As citizens, we each have a duty to put country above partisanship to defend our Constitution.

“That is why I will be casting my vote for Vice President Kamala Harris.”


How has Trump responded?

Trump responded on his Truth Social platform by calling the former vice president “an irrelevant RINO, along with his daughter.”

The acronym stands for “Republican in name only.”

Asked for comment, Trump spokesperson Steven Cheung said: “Who is Liz Cheney?”

The campaign also pointed to a comment Ms Cheney posted online four years ago in which she called Ms Harris a “radical liberal.”

Jen O’Malley Dillon, the Democrat nominee’s campaign chair, released a statement saying: “The Vice President is proud to have the support of Vice President Cheney, and deeply respects his courage to put country over party.”
Has Cheney clashed with Trump before?

Mr Cheney’s statement on Friday was similar to a 2022 campaign ad for his daughter as she sought a fourth term as Wyoming’s lone congresswoman.

In it, he called Trump a “coward” for trying to “steal the last election using lies and violence to keep himself in power after the voters had rejected him.”

The ad did not help his daughter in the deep-red state that once held the Cheney family dear but is now thoroughly in Trump’s corner.

By a more than 2-to-1 margin, Ms Cheney lost her Republican primary to Trump-endorsed attorney Harriet Hageman.
Has Cheney ever backed the Democrats before?

Dick Cheney has been friends with Democrats over the years but never supported one for president.

Both he and his daughter backed Trump in 2016, but Ms Cheney criticized Trump’s foreign policy decisions.

In response, Trump criticized the “endless wars” in Afghanistan and Iraq launched when Dick Cheney was vice president.

It’s unclear if either Cheney supported Trump in 2020.

Meanwhile, their home state of Wyoming delivered Trump his widest margin of victory that year.

By 2021, Ms Cheney’s vote to impeach Trump and her investigation into him for the 2021 US Capitol riot turned Trump and most of the GOP against her.
Which other Republicans have turned against Trump?

Cheney ally Rep. Adam Kinzinger of Illinois, a Republican Trump critic endorsed Biden earlier this year and spoke in support of Harris at the Democratic National Convention in August.

Several other top Republicans have come out in support of Harris while some, including Sen. Mitt Romney and former Vice President Mike Pence, who served alongside Trump, say they won’t be voting for the former President.

Of them only Romney, who is not seeking re-election, is still in office.
Stakeholder in Trump's Truth Social parent company wins court ruling over sale of shares

A federal judge in Delaware has ruled in favor of a firm seeking assurance that it will be able to sell its minority stake in the parent company of former president Donald Trump’s Truth Social platform.

The judge on Friday granted summary judgment to Florida-based United Atlantic Ventures LLC in a lawsuit filed against Minnesota-based Odyssey Transfer and Trust Co., a business that handles securities transfers among registered shareholders.

UAV is owned by Andrew Litinsky and Wesley Moss, former contestants on Trump’s TV show, “The Apprentice” who also helped facilitate a merger that took Trump Media public in March.

Since then, UAV and Trump Media have been battling in courts in both Delaware and Florida over UAV’s stake in the company. Attorneys for Trump Media assured a state judge in Delaware earlier this year that UAV was entitled to an 8.6% stake and would suffer no merger-related dilution. They now contend, however, that UAV is not entitled to its shares because of pre-merger mismanagement by Litinsky and Moss.

Friday’s ruling involves UAV’s concerns that it will not receive its Trump Media shares, currently valued at about $350 million, from Odyssey when a post-merger lockup period expires Sept. 19. According to court filings, Odyssey told UAV earlier this year that it would be taking direction from TMTG and its lawyers.

After Odyssey filed a lawsuit, the parties appeared to have reached a resolution, with Odyssey saying it would remove transfer restrictions on the share after the lockup period expires “without preference to any TMTG shareholder.” After seeking approval from Trump Media, however, Odyssey tried to change that language to “on the same basis as other similarly situated TMTG shareholders.”

Trump holds about 115 million TMTG shares, or roughly 60% of the company’s outstanding shares.

U.S. District Judge Gregory Williams questioned Odyssey’s conduct, noting that it claimed the language change was “immaterial,” while allowing it to scuttle settlement negotiations.

“Even outside settlement negotiations, Odyssey’s conduct has been elusive,” Williams wrote.

Williams ordered that when Odyssey is notified by TMTG of the expiration of the lockup provisions, it must promptly notify UAV, remove transfer restrictions on all shares and not interfere with the delivery of the shares.


TMTG’s share price hit a high of $79.38 on its first day of trading but is now hovering around $17, closing Friday at $17.10.

Abstract



This study explored the unique connections between music and mathematics as perceived by four groups of experts: professional mathematicians and musicians, as well as teacher educators in these two fields. Using 2 × 2 study design, we studied four groups of participants, comprising theorists and educators from various Israeli universities. During semi-structured interviews, the study participants were asked about their views on the connections between mathematics and music. This study proposes a model of experts’ conceptions of the connection between mathematics and music, which is of descriptive and explanatory power. that reveals differences between the four groups of experts. Theoreticians in both disciplines highlighted Mathematics as a key tool for music analysis and creation. Musical educators emphasized the role of music as a tool for learning mathematics. All the study participants, independently of the field of their expertise, value structure, beauty, sense of wonder, freedom and creative thinking as characteristics of both fields. Additionally, all the experts hold conceptions of the importance of integrating music and mathematics into various discipline. This study opened new doors for future research wherein utilization of experts’ insights to craft integrated study modules of music and mathematics can be explored, a pursuit that carries substantial significance.




Introduction



The connection between Western music and mathematics has been recognized since the days of Pythagoras, Plato and Aristotle, who wrote about the overlap and parallels between the two disciplines. Both disciplines – music and mathematics – are expressed through the use of representative language and symbolic notation (Papadopoulos 2002). Mathematical concepts such as symmetry, patterns, ratio, and division are expressed in music. In music, intervals, rhythm, duration, speed, and many musical concepts are naturally represented by numbers (Bamberger and Disessa 2003). For example, the intervals between harmonic notes in music are determined by ratios of small whole numbers. When plucking two strings of the same length, the ratio between their lengths is 1:1, resulting in identical and harmonious sounds (sounds that blend well together). Moreover, differing ratios of string lengths will produce various harmonic intervals, such as the octave (string ratio of 1:2), the fifth (2:3), and the fourth (3:4).

Music was a subject of research among mathematicians such as Descartes, Kepler, and Euler, and on the other hand musicians were attracted to the possibilities inherent in the science of mathematics for analyzing works and composing (Wollenberg 2003). Compositional methods that draw inspiration from mathematical ideas included, among others, counterpoint (a second voice that appears simultaneously with the first voice in a polyphonic texture), a crab canon (the second voice is an imitation of the first voice in reverse), or a palindrome (a section that can be played from beginning to end and from end to beginning, in mathematics y = −x), and geometric designs of musical melodies (for example reflective symmetry, where a melody repeats itself in a mirrored fashion). In addition, mathematical images in Western music are expressed musically in the theory of harmony, the theory of rhythm, and the theory of forms. The theory of harmony reveals a fundamental regularity in how sounds are combined simultaneously, how they relate to one another, and how they are distributed over time. The theory of rhythm refers to how the sounds are organized in time and the continuation relationships between them. And finally, the theory of forms addresses how musical events are organized and the proportions created between musical parts (Douthett 2008; Johnson 2008; Rothstein 2006). In light thereof, the current study aims to uncover the profound interconnections between the disciplines, as perceived by mathematicians, musicians, and educators in teacher training programs. By adopting a wholistic perspective, this research seeks to highlight the practical relevance of these interdisciplinary connections both in training teachers and instructing students.

Student involvement and innovative teaching methods in a biophilic design education pilot elective course in interior architecture

 

Abstract

Biophilic design has gained popularity in interior design areas owing to its numerous advantages. Nevertheless, globally, Interior Architecture/Interior Architecture and Environmental Design departments lack adequate biophilic design courses in their curricula. This research investigates the impact of involving students in syllabus design and applying innovative teaching methods in a pilot elective course focused on biophilic design in interior spaces on student engagement and course sustainability. A new pilot elective course was introduced in the 2022–2023 Spring Semester at the Interior Architecture Department, Faculty of Architecture, Near East University, aiming to establish an enduring and captivating learning environment for students. Initially, a focus group study was conducted to measure students’ awareness of biophilic design and integrate their ideas regarding innovative learning methods into the syllabus for an engaging elective course. Strategies like interactive learning tools, group tasks, and peer assessments were incorporated throughout the course to enhance engagement. Analysis of end-of-course surveys and student observations revealed an augmented awareness of biophilic design among students and a positive influence of innovative learning methods on course sustainability. Thus, the study suggests that an elective course offers the potential to mitigate the deficiency of biophilic design integration in undergraduate programs, augmenting students’ awareness in this field. Moreover, new elective courses could deliver more sustainable and engaging learning experiences for enrolled students when structured through student involvement and innovative learning methods.

Muhammad Shahzeb Khan was arrested in Canada for allegedly planning a terrorist attack in New York City on October 7 - the anniversary of Hamas' attack

A Pakistani man, Muhammad Shahzeb Khan, was arrested in Canada after he allegedly attempted to aid the Islamic State of Iraq and al-Sham (ISIS) in planning a terrorist attack in New York City around October 7, according to the the US Department of Justice.

Muhammad Shahzeb Khan, allegedly planned the terrorist attack “with the intent of slaughtering in the name of ISIS, as many Jewish people as possible”, attorney general Merrick B Garland said in a statement by the US Department of Justice.
Also Read: Who was Aysenur Ezgi Eygi? Turkish-American killed in Israeli-occupied West Bank

Director of the FBI Christopher Wray also chimed in, expressing pride in the team that disrupted Khan's plan. "The FBI will continue to work closely with our partners to investigate and hold accountable those who seek to commit violence in the name of ISIS or other terrorist organizations. Fighting terrorism remains the FBI's top priority," he said.

Muhammad Shahzeb Khan, had allegedly attempted to travel from Canada to New York City to carry out a mass shooting at a Jewish center in Brooklyn, New York, to show his support for ISIS.

Khan's digital footprint showed that he began posting on social media about his support for ISISI and was communicating with others on an encrypted messaging application around November 2023.

During this time, Khan distributed ISIS propaganda videos and literature. While he was doing so, he began communicating with two undercover law enforcement officers, according to the US Department of Justice.

Muhammad Shahzeb Khan would tell the undercover agents how they could obtain AR-style assault rifles, ammunition, and other materials to carry out the attacks, and identified where the attacks would take place as well.

He also gave them details about how he would cross the border from Canada into the United States to conduct the attacks.

According to the US Department of Justice, during these conversations, Khan explained that "Oct 7th and Oct 11th are the best days for targeting the Jews" because October 7 is the anniversary of the Hamas attack on Israel. October 11 was also mentioned as it was Yom Kippur, a Jewish religious holiday.

Khan is now being charged with attempting to provide material support and resources to a designated foreign terrorist organisation. If he is convicted, he will face a maximum sentence of 20 years in prison.

On October 7, when Khan planned his attack, Hamas attacked Israel, killing an injuring several civilians, after which the two entities have been in conflict for close to a year.

In short:


A new project will map colonies of endangered giant Gippsland earthworms on farms.

The worms, among the biggest in the world, grow to one metre long and are rarely seen above ground.

What's next?


Researchers want to know more about soil conditions for the species to better protect it.

Uder the steep rolling hills of eastern Victoria are "gurgling" creatures farmers can hear but rarely lay eyes on.

"It's kind of a strange little thing, that we're passionate about something we never see,” farm manager Burke Brandon said.

"But still, we know they're there.

"They're kind of like our hidden allies."

The south Gippsland organic beef and lamb farmer is talking about a species of annelid worm called the giant Gippsland earthworm (Megascolides australis).

It earns the name "giant" because an average adult is a metre long — making it one of the biggest earthworms in the world.

Mr Brandon had heard people talk about them but it was not until a mudslide about 10 years ago that he found them on his property.

"I actually saw a part of a giant earthworm, which was quite a surprise when you actually see how big they are in real life," he said.

"And we have seen cases where there's been accidental erosion or a landslip ... and you can see in the soil profile these hundreds of little holes in the soil the size of your finger."

Stomp around and listen

The farmer is getting to know where these elusive creatures live on his property at Moyarra, 125 kilometres south-east of Melbourne, as they don’t travel far.

"You know they'll always be roughly in the same area," Mr Brandon said.

"The more we stomp around on the surface, the more you hear them moving," Mr Brandon said.

"They feel the vibrations of you walking around, that's when they scurry back into their holes.


"It makes a gurgling sound, like you've let the water out of the bathtub."

Mr Brandon now wants to understand more about protecting the species listed as endangered in Victoria.

He is one of several farmers taking part in a project mapping the sites of local colonies.
Not too wet, not too dry

The species is endemic to west and south Gippsland and is fussy about its underground home.

Dr Beverley Van Praagh has been studying the worms for more than 30 years and describes them as the "Goldilocks of the earthworm world".

"They don’t like it too wet, they don't like it too dry. It has to be just right for them to be able to survive in those clay soils," Dr Van Praagh said.

The biggest threats to the species are changes in soil conditions, which could come from new housing estates, damming a creek or redirecting a waterway, she said.

Another less obvious threat could be planting trees on top of them with the best intentions.

"When people plant dense vegetation on top of earthworm habitat, it sucks the water out of the soil," she said.

An idyllic rural home

Most giant Gippsland earthworms are found on private farming land.

A telltale clue the species is lurking under the soil is terracing across hill sides.

Dr Van Praagh said the worms are often found along the banks of small creeks or tributaries or on south or west-facing hill slopes.

But when it comes to the exact soil conditions they like, there are knowledge gaps.

Gippsland Threatened Species Action Group and the Bass Coast and South Gippsland Landcare Networks are leading a new project to better understand these parameters.

It has federal funding under the Saving Native Species Program and will involve mapping colonies on private land and studying the hydrology with probes.

Co-existing with worms

The project aims to help farmers understand how to coexist with giant earthworms and still have productive farmland.

Researchers will track soil hydrology over time, looking at changes in moisture, temperature and oxygen.

Mr Brandon hopes to help preserve the species on his property for years.


"Some areas we may fence off so we know we can manage that area differently with grazing," he said.

"There is the potential for those areas to be revegetated with plants that coexist well with the earthworms, so grasses and ferns and sedges and small shrubs, but certainly not eucalyptus trees or deep-rooted trees.

"It's about being aware of how we can incorporate those [earthworm] communities in our whole farm plan, into our long-term future."
