Polar bear fur’s natural ability to resist ice formation could pave the way for safer, more sustainable solutions to prevent ice buildup across industries such as aviation and renewable energy, according to researchers at the University of Surrey.  An international study published in Science Advances has explored the anti-icing properties of polar bear fur in extreme Arctic conditions, revealing a unique mix of lipids in the fur’s sebum – an oily substance produced by the skin - that drastically reduces ice adhesion. ...

If you can wiggle your ears, you can use muscles that helped our distant ancestors listen closely. These auricular muscles helped change the shape of the pinna, or the shell of the ear, funneling sound to the eardrums. Millions of years ago, our ancestors stopped using them, so humans’ auricular muscles are only vestigial. But now scientists examining the function of these muscles have discovered that they activate when we’re trying to listen to competing sounds.  “There are three large muscles which connect the auricle to the skull and scalp and are important for ear ...

Researchers have long known that patients who leave emergency departments before medically advised use more emergency care services, are more likely to be readmitted to the hospital and face higher costs of care—as well as increased mortality rates. Until now, however, little has been known about national, multi-year trends, including the impact of the COVID-19 pandemic on this phenomenon. “In addition, most studies have focused on specific subgroups of patients, such as those with stroke or those with appendicitis who leave after surgery,” said Elena Andreyeva, PhD, a faculty member with the Texas A&M University School of Public ...

As grasslands get abandoned, controlled burning is discussed as a labor-saving method of keeping forests at bay. A Kobe University research team found that this method results in higher biodiversity and a higher prevalence of endangered plant species in some grasslands compared to others, depending on what soils they grow on. Humans have been keeping grasslands since millennia by grazing, mowing and controlled burning, all of these are means to keep forests from overgrowing the grasslands. Grazing and mowing are, however, labor intensive and as rural areas become increasingly depopulated, grasslands have been disappearing worldwide. One consequence ...

Increased use of ventilation and air cleaners, designed to mitigate the spread of viral infections in hospitals, is likely to have unpredictable effects and may cause viral particles to move around more, according to a new study from researchers at UCL and UCLH. In the study, published in Aerosol Science & Technology, researchers investigated the effect of using built-in mechanical ventilation and portable air cleaners (PACs)1 upon the spread of airborne particles, which are similar to those breathed ...

CAR T cell therapy is one of the most promising new cancer treatments to emerge in recent years. It involves removing a patient’s own immune T cells and engineering them to recognize specific targets on the surface of the cancer cell. A major limitation of this type of CAR T cell therapy, called autologous therapy, is that the cells are taken from the patient and must be custom-made into a treatment. This requires patients to wait until their cells are modified for infusion — precious time they may not have. Now research done at Memorial Sloan ...

Millions of women undergo episiotomies during childbirth every year, yet the mechanics behind these surgical cuts remain largely unstudied. A new research project is poised to change that, addressing this significant gap in women’s health. An episiotomy involves cutting the pelvic-floor muscles to aid delivery, a technique currently guided largely by a surgeon’s personal judgment and experience. While intended to prevent severe vaginal tears or other complications during delivery, the procedure itself can lead to lasting pain, incontinence, infection, ...

Experts from the global Earth science community – including a scientist from the University of Calgary – have pieced together what happened during the massive Sikkim flood to try to help others prepare for similar disasters. On Oct. 3, 2023, a multi-hazard cascade in the Sikkim Himalaya, India, was triggered by a permanently frozen (permafrost) lateral moraine – debris from erosion along a glacier – collapsing into South Lhonak Lake. “A landslide went into a lake and that triggered a wave that eroded a dam at the end of the lake, which resulted in a slurry-like flood for hundreds of kilometres,” explains Dr. Dan ...

Steans Director of the RUSH BMO Institute for Health Equity. “Yet, we know from medical literature that certain groups receive ...

Your parents were right: Scratching an itchy rash really does make it worse. Now we know why, thanks to new research published today in the journal Science that uncovers how scratching aggravates inflammation and swelling in a mouse model of a type of eczema called allergic contact dermatitis. “At first, these findings seemed to introduce a paradox: If scratching an itch is bad for us, why does it feel so good?” said senior author Daniel Kaplan, M.D., Ph.D., professor of dermatology and immunology at the University of Pittsburgh. “Scratching is often pleasurable, which suggests ...

PITTSBURGH, Jan. 30, 2025 – A prophylactic antibody-based immune therapy protects monkeys against severe disease caused by H5N1 avian flu, University of Pittsburgh and NIH Vaccine Research Center researchers report today in Science. The broadly neutralizing antibody, which recognizes a relatively stable region of the bird flu virus, is less prone to losing its efficacy than antibodies targeting influenza’s more mutation-prone structures. This feature ensures that the immune protection can withstand the possible emergence of virus variants, akin to the SARS-CoV-2 mutants that ...

  Polar bears in Western Hudson Bay have seen their population nearly halved over the last several decades, largely due to dwindling sea ice and limited hunting opportunities, according to the findings of a novel bioenergetic model using data spanning more than 40 years. The findings reveal the relationship between bears’ individual energy needs and environmental limitations in driving population trends, highlighting energy as the central limiting factor behind the decline of a key Arctic apex predator. The Arctic is warming ...

India, the world’s most populated country, has been successfully working to recover one of the largest, and most iconic, carnivores, the tiger, for decades. Protection, prey, peace, and prosperity have been key factors in the tiger recovery within this densely populated country, according to a new study. According to its authors, success in India offers a rare opportunity to explore the socio-ecological factors influencing tiger recovery more broadly. Earth’s large carnivores, crucial for maintaining ecosystem health, are among the most threatened species, impacted ...

New research uncovers the dual nature of scratching an itch; although it can worsen skin inflammation, it can also boost immune defenses against bacterial infections at the injury site. The findings shed light on a pharmacologically targetable pathway that explains how scratching triggers inflammation, resolving the paradox of scratching as both a harmful pathological process and a beneficial evolutionary adaptation. Scratching is a natural, instinctive response to the sensation of itching, and it plays a central role in many ...

In a comprehensive analysis, researchers present the divers, causes, and impacts of the catastrophic 2023 Sikkim glacial lake outburst flood (GLOF). The findings stress the urgent need to enhance GLOF hazard assessments and improve prediction and early warning systems as melting glaciers steadily raise the risk of GLOFs in the Himalayan region. South Lhonak Lake – perched at 5200 meters above sea level in the Upper Teesta basin of Sikkim, India – is among the region's largest and most rapidly expanding glacial lakes, posing severe hazards due to its ...

The most complex engineering of human cell lines ever has been achieved by scientists, revealing that our genomes are more resilient to significant structural changes than was previously thought. Researchers from the Wellcome Sanger Institute, Imperial College London, Harvard University in the US and their collaborators used CRISPR prime editing to create multiple versions of human genomes in cell lines, each with different structural changes. Using genome sequencing, they were able to analyse the genetic effects of these structural variations on cell survival. The research, published today (30 January) in Science, ...

U of T Scarborough researchers have directly linked population decline in polar bears living in Western Hudson Bay to shrinking sea ice caused by climate change. The researchers developed a model that finds population decline is the result of the bears not getting enough energy, and that’s due to a lack of food caused by shorter hunting seasons on dwindling sea ice. “A loss of sea ice means bears spend less time hunting seals and more time fasting on land,” says Louise Archer, a U of T Scarborough postdoc and lead author of the study. “This negatively affects the bears’ energy ...
