India, China account for 6 in 10 new research visas in S. Korea

 

Researchers from India and China accounted for 60 percent of all foreign research visas issued by South Korea over the past five years, a report showed Tuesday.

According to data submitted by the Ministry of Justice to Rep. Lee Jeong-heon of the ruling Democratic Party of Korea, 4,629 foreigners entered South Korea on E-3 research visas between 2020 and August 2025.

The E-3 visa is issued to foreign researchers engaged in natural sciences or advanced industrial technology research and development at public or private institutions in Korea.

Of the total, Indian nationals were the largest share with 2,262 researchers, or nearly half of all E-3 visa recipients during the period. China followed with 518 recipients. Together, researchers from India and China accounted for 60.1 percent of the total.

Other key countries of origin included Pakistan with 304 individuals, Iran with 184 and Vietnam with 162, the report said.

The number of E-3 visa recipients has declined for three consecutive years. After peaking at 1,059 in 2021, the number fell to 1,031 in 2022, 835 in 2023 and 621 last year. For the first eight months of 2025, the figure stood at 444.

However, the number of foreign residents on E-3 visas has remained fairly stable, with 3,122 in January 2020, compared to 3,263 at the end of last month, according to data from the Korean Immigration Service. Indians and Chinese made up the largest numbers in August, with 1,144, and 361 respectively, but Vietnamese were the third-largest with 305.

Foreign researchers may also be in Korea on other visas, especially residence visas, including the F-4 visa most ethnic Korean researchers qualify for.

Rep. Lee called for reducing reliance on certain countries for foreign researchers, noting that the continued decline in skilled foreign workers could pose security concerns and potential supply issues if relations with the countries of origin worsen.

“While expanding the foundation for global cooperation, we must also establish a research security framework to ensure the sustainable attraction of talent.”

Scientists just found the hidden cosmic fingerprints of dark matter

 

A Rutgers-led team of scientists, together with collaborators, has traced the invisible dark matter scaffolding of the universe by studying more than 100,000 Lyman-alpha emitting galaxies. By examining how these galaxies clustered across three distinct eras shortly after the Big Bang, the researchers were able to map concentrations of dark matter. These cosmic “fingerprints” provide crucial evidence of how galaxies grow and evolve, offering new insights into the expansion and formation of the universe.

New Research Details Hidden Health Risks of Methane Emissions

 

Newly published research from PSE Healthy Energy, a US-based nonprofit research organization, highlights the hidden dangers of methane leaks, an often overlooked but serious threat to both the climate and public health.

Methane leaks have become a key political issue between the United States and the European Union, with US officials actively opposing a new EU methane regulation that would affect major oil and gas exporters to the EU. US lawmakers also recently rolled back a domestic methane fee.

Methane, the primary component of natural gas, is a potent climate pollutant released throughout the oil and gas supply chain. These emissions are accompanied by toxic pollutants like benzene, a known carcinogen.  Using satellite data and air quality records, PSE identified “super-emitter” events – which they define as methane emissions exceeding 100 kilograms per hour – across 11 US states between 2016 and 2025. PSE’s model highlighted areas with serious public health risks from these emissions, which can result from events like well blowouts or pipeline leaks, though the causes are often unknown according to PSE researchers.

The findings are alarming: methane-related air pollution threatens the health of not only oil and gas workers and nearby fence-line communities, but also people in homes, schools, and health centers as far as 19 kilometers away from the source, according to peer-reviewed research. PSE Health Energy estimates that at least 126,000 people in the US may be exposed, but since the study covers only a small fraction of methane releases, this likely underestimates the total number of people at risk. Millions of Americans live close to oil and gas infrastructure.

Meanwhile, a critical 2024 EU methane regulation—still awaiting full implementation by member states—could be included in the European Commission’s “Omnibus” program, which aims to “simplify” legislation, amid pressure from US officials and oil and gas lobby groups. If fully enforced, the regulation would require oil and gas companies—both operating in the EU and those exporting to Europe—to track, report, and ultimately reduce the methane intensity of their operations.


The EU should maintain a firm stance on the regulation’s implementation timeline and prioritize rigorous enforcement. This new research serves as an urgent warning: weakening or delaying these measures would not only undermine global climate goals but also leave many communities exposed to invisible, toxic air pollution.

Trump's Harvard cuts threaten a giant in the biomedical research community: A database about the tiny fruit fly

 

For more than a century, the humble fruit fly has paved the way for many critical scientific breakthroughs.

This tiny insect helped researchers figure out that X-rays can cause genetic mutations. That genes are passed on from parent to child through chromosomes. That a gene called period helps our bodies keep time — and that disruptions to that internal clock can lead to jet lag and increased risk for neurological and metabolic diseases.


Those discoveries, along with nearly 90,000 other studies, are part of a key online database called FlyBase that researchers routinely use to help them more quickly design new experiments. These tests explore the underlying causes of disease and could help with the development of new treatments. Science builds on prior insights, and a handy repository of past advances serves as kindling for future discoveries.

The website receives about 770,000 page views each month from scientists working around the world on developing personalized therapies for rare cancers, modeling human neurodegenerative diseases and screening drug candidates for conditions like Alzheimer’s.

Now, that critical resource is on the brink of layoffs that endanger its future and ability to make research more efficient.

This spring, the Trump administration, as part of its broader $2.2 billion funding cuts at Harvard University, rescinded a grant used to maintain FlyBase.

“I use FlyBase every single day. It’s so essential,” said Celeste Berg, a professor of genome sciences at the University of Washington, who is not part of the team that operates FlyBase. “What we know about human genes and how they function comes almost completely from model systems like drosophila.”

Humans share about 60% of our genes with fruit flies, also known by their scientific name Drosophila melanogaster.

FlyBase’s now-uncertain future highlights just how interconnected and interdependent research efforts are and how the effects of funding cuts to one institution can ripple worldwide. More than 4,000 labs use FlyBase.

Harvard was receiving about $2 million a year in federal funding to maintain FlyBase, which was the vast majority of the website’s total operating budget. But the University of New Mexico, Indiana University and the University of Cambridge in England are partners that help Harvard manage FlyBase and are beneficiaries, too.

“This is not just affecting Harvard,” said Brian Calvi, a professor of biology at Indiana University, who is part of the FlyBase management team. “The ripple effect is to the international biomedical research community.”

Harvard’s Faculty of Arts and Sciences rescued FlyBase with interim funding, but that support will cease in October, according to Norbert Perrimon, a professor of developmental biology at Harvard Medical School.



A judge earlier this month ordered the Trump administration to restore funding to Harvard researchers who lost grants, but money has not begun to flow to FlyBase, Perrimon said. The administration has promised to appeal the decision, which could halt the flow of funds.

AVC resident to present research at international surgery summit

 

This October, Dr. Yoko Nakamae, a large animal surgery resident at the Atlantic Veterinary College (AVC) at the University of Prince Edward Island (UPEI), will travel to Seattle, Washington, to present her research at the American College of Veterinary Surgeons (ACVS) Surgery Summit, the premier surgical conference for veterinary professionals worldwide.

Dr. Nakamae is one of five surgery residents selected to receive the ACVS Resident Education Travel Grant, allowing her to share findings from her master’s research project, “Comparison of Alcohol-and Chlorhexidine-Based Antisepsis for Surgical Site Preparation in Equine Arthroscopy.” While the project may have Dr. Nakamae’s name on it, she emphasizes that it was a collaborative effort with strong support from her mentors and colleagues.

“I’m the one who is presenting the research, but so many people helped me,” she says, crediting Dr. Aimie Doyle, Dr. Yvonne Elce, as well as Matt Saab and Dr. J. McClure, for their guidance and collaboration.

For Dr. Nakamae, the opportunity is both exciting and humbling.

“I’m excited and nervous at the same time,” she admits. “Many well-known and highly regarded surgeons will be there—people I’ve read about or learned from. It feels incredible to be in the same room with them.”

The ACVS Surgery Summit brings together veterinary surgeons, residents, and researchers from around the globe to share new knowledge, refine surgical techniques, and explore emerging innovations in the field. Presenting at such a high-profile event offers Dr. Nakamae the chance to showcase her team’s work while also connecting with leading experts.

“Of course, I’m presenting my research, but it’s also about meeting so many people and making good connections for the future,” she explains. “Hearing what others are working on and exchanging ideas is really inspiring. It gives me motivation for what I want to do next in my career.”

Her participation at the Surgery Summit reflects not only her dedication, but also the strong mentorship and collaboration that is at the heart of the AVC. Residents, faculty, and researchers work closely together to advance veterinary medicine and train the next generation of specialists to serve both animals and their communities.

Scientists Say Ice Has a Hidden Superpower: It Can Generate Electricity

It may not seem that ice does much except make roads slick during winter, cool down frost-rimmed drinks in the summer, and rise majestically from the ocean in the form of distant glaciers most of us will probably never see up close. It’s certainly important, but it doesn’t seem particularly exciting.

But ice, as it turns out, hides a superpower. According to a team of researchers, it turns out that ice is what’s called flexoelectric, which means that it generates electricity in response to the physical stress of bending (and similar types of deformation, such as twisting). This is different from piezoelectric materials, which accumulate an electric charge when subjected to pressure (quartz is piezoelectric). Obviously, an ice cube is not going to bend, but as a team of researchers found, electric properties can be activated by bending a much thinner sheet of ice. The team—led by physicist Xin Wen from Xi’an Jiaotong University in Xi’an, China—also tried the experiment with salty ice, and found that not only can it, too, generate electric charge, it can create one a thousand times stronger than ice alone.

How the US became a science superpower

 

America is awesome at science. For as long as most of us have been alive, United States scientists have published more research, been cited more often by other scientists, earned more patents, and even won more Nobel Prizes than any other nation.

All that scientific expertise has helped make the U.S. the most prosperous nation on Earth and led to longer and easier lives here and around the world. But until World War II, the U.S. often sat on the sidelines of scientific progress. With national security on the line, the federal government, through policy and strategic investments, set about turning America into the world leader in science.

Now, amid federal attacks on university research and the government agencies that fund it, America is on the verge of relinquishing its scientific dominance for the first time in eight decades.

To learn more about how we got here, and what could happen next, we called up two experts who’ve dedicated their careers to understanding how America built itself into the most innovative nation on Earth.

Centromere Sequencing Fills Gaps in Human Cell Line Genome

 

Due to their repetitive and complex DNA sequences, centromeres have been viewed as the "black boxes" of the genome for decades. Often overlooked in sequencing projects but playing a critical role in cell division, centromeres are a significant aspect of the genome that scientists are only just starting to understand.

“While the rest of the genome shuffles between the maternal and paternal origins, centromeres are inherited intact: one from the maternal and one from the paternal origin for each chromosome, carrying [ancestral] information,” said Simona Giunta, a human genomics researcher at the Sapienza University of Rome.

In a new study, Giunta and her team released the near-complete genome sequence—for the first time including both parental centromeres—of a human diploid cell line commonly used in laboratories around the world.1 The study establishes a foundation for generating high-quality reference genomes across all widely used cell lines, ensuring that functional genomic studies more accurately capture patient-specific genetic variation and better inform the development of tailored therapies.

When Giunta established her lab in 2021, she embarked on a quest to fill the unresolved gaps left in the official human genome reference at the time, especially around centromeres. She and her team described in a recent Science paper that human centromeres have a unique organization that is specific to each chromosome and consistent in different individuals.2 Now, in this new study, they released the assembled genome sequence of a reference human cell line to validate their prior results. "We put centromeres and any other region of the genome in the picture, opening a new way to do genome biology in every field," Giunta said.

Derived from a noncancerous human retinal pigment epithelial (RPE) cell, RPE-1 is one of the most used reference cell line in experimental settings, often serving as a key model in drug discovery and genetic disease studies. As a diploid cell line, the RPE-1 genome contains both maternal and paternal centromeres, providing a perfect platform to enhance scientists’ understanding of the role of centromeric DNA in cell regulation and disease.

Highly repetitive regions, such as centromeres, are notoriously challenging to assemble. Therefore, the team utilized long-read sequencing technologies and advanced computational algorithms to capture these sequences in unprecedented detail. Remarkably, when compared with publicly available human reference genomes, most of the RPE-1 sequence maintains close similarity to recent high-quality human genomes, such as those found in the Human Pangenome Reference Consortium. They also found that there was no evidence of polyploidy or other extensive chromosomal rearrangements in the RPE-1 centromere sequences, underscoring the cell line’s continued value as a model for studying human cellular processes and functional genomics.
