New 3D glacier visualizations provide insights into a hotter Earth

2025-07-01
COLUMBUS, Ohio – As glaciers retreat due to a rise in global temperatures, one study shows detailed 3D elevation models could drastically improve predictions about how they react to Earth’s warming climate.   While only 10% of Earth is covered in glacial ice, these masses have far-reaching impacts on all the world’s ecosystems. Rapid melting can trigger natural disasters, and glaciers help to regulate the planet’s temperature and sea level and are sources of pristine fresh drinking water. To better differentiate between seasonal ice loss and that caused by long-term climate trends, ...

Creativity across disciplines

2025-07-01
In a Perspective, Julio M. Ottino describes different classes of creativity and proposes a benchmark for the highest level of creativity. Combinative creativity is the process of combining existing elements to create new solutions, while transformative creativity leads to entirely new frameworks. But beyond the breakthroughs of transformative creativity, according to Ottino, is the “break-with,” a conceptual advance that destroys previous worldviews completely and ushers in a new order. Advances that rise to the level of a break-with include quantum mechanics in physics and cubism in ...

Consequences of low Antarctic sea ice

2025-07-01
Antarctic sea ice is more than just a platform for penguins. The sea ice’s high reflectivity influences the whole Earth’s climate, and the ice is a key habitat for underwater as well as above-water ecosystems. Antarctic sea ice cover is becoming much more variable as the climate changes; there has been a string of record high years followed by years with record low areas of ice. Edward Doddridge and colleagues studied these record-low years, which they expect will become more common as the climate warms. Using observations ...

Epilepsy self-management program shows promise to control seizures, improve mood and quality of life

2025-07-01
CLEVELAND—Epilepsy is among the most common neurological conditions, marked by unpredictable seizures, accidents and injuries, reduced quality of life, stigma and—in the worst case—premature death.  But a program—developed over several years by a Case Western Reserve University-led research team—that teaches people with epilepsy how to “self-manage” their disorder is showing positive results. The program has been found to help people with epilepsy reduce related health complications and improve their mood and quality of life, according to a new study recently ...

Fat may play an important role in brain metabolism

2025-07-01
While glucose, or sugar, is a well-known fuel for the brain, Weill Cornell Medicine researchers have demonstrated that electrical activity in synapses—the junctions between neurons where communication occurs—can lead to the use of lipid or fat droplets as an energy source. The study, published July 1 in Nature Metabolism, challenges “the long-standing dogma that the brain doesn’t burn fat,” said principal investigator Dr. Timothy A. Ryan, professor of biochemistry and of biochemistry in anesthesiology, and the Tri-Institutional ...

New study finds no lasting impact of pandemic pet ownership on human well-being

2025-07-01
A new study challenges the belief in a universal “pet effect” on human well-being. Using data collected during COVID-19 lockdowns, researchers found no significant change in respondents' well-being when they acquired or lost a pet in their household. The findings suggest that, even during a time of extreme isolation, human-animal bonds may not be as emotionally transformative as we like to believe. Humans and their pets, a match made in heaven? Does adopting a new dog make you happier and less lonely? It is now commonplace to associate pet ownership with health ...

Gut microbes could protect us from toxic ‘forever chemicals’

2025-07-01
Scientists have discovered that certain species of microbe found in the human gut can absorb PFAS - the toxic and long-lasting ‘forever chemicals.’ They say boosting these species in our gut microbiome could help protect us from the harmful effects of PFAS. PFAS have been linked with a range of health issues including decreased fertility, developmental delays in children, and a higher risk of certain cancers and cardiovascular diseases. Scientists at the University of Cambridge have identified a family of bacterial species, found naturally in the human gut, that absorb various PFAS molecules from their surroundings.  When nine of these ...

Novel modelling links sea ice loss to Antarctic ice shelf calving events

2025-07-01
New research has for the first time tracked ice shelf, sea ice and ocean swell wave conditions over multiple years in the lead-ups to three large-scale iceberg ‘calving’ events in Antarctica, revealing common patterns. Published in Nature Geoscience, the study, led by the Universities of Melbourne and Adelaide, found long periods of sea ice loss surrounding the ice shelves in the six to 18 months prior to calving, as well as the collapse of the ‘landfast’ sea ice attached to the ice shelves only weeks prior to the calving events. University of Melbourne Professor Luke Bennetts explained that the researchers ...

Scientists can tell how fast you're aging from a single brain scan

2025-07-01
DURHAM, N.C. -- Any high school reunion is a sharp reminder that some people age more gracefully than others. Some enter their older years still physically spry and mentally sharp. Others start feeling frail or forgetful much earlier in life than expected. “The way we age as we get older is quite distinct from how many times we’ve traveled around the sun,” said Ahmad Hariri, professor of psychology and neuroscience at Duke University. Now, scientists at Duke, Harvard and the University of Otago in New Zealand have ...

Turning social fragmentation into action through discovering relatedness

2025-07-01
Discovering relatedness outside of a topical issue helps diverse groups to overcome differences and develop action for social change. The Kobe University addition to educational theory offers a framework to analyze and promote intersectional learning. To achieve social change in a fragmented modern society, individuals from diverse backgrounds need to join together and develop a common plan for action. This is important especially for education related to social change, where groups of varying involvement in a particular issue, e.g., learners and teachers, interact in a structured setting. Current educational theories fall short of offering a framework of how such cultural differences ...

Cheese may really be giving you nightmares, scientists find

2025-07-01
Scientists have found that eating too much dairy could ruin your sleep. Researchers questioned more than 1,000 students about the quality of their sleep, their eating habits, and any perceived link between the two, and found a strong association between nightmares and lactose intolerance — potentially because gas or stomach pain during the night affects people’s dreams.   “Nightmare severity is robustly associated with lactose intolerance and other food allergies,” said Dr Tore Nielsen of Université de Montréal, lead author of the article in Frontiers in Psychology. “These new findings imply that changing eating habits for ...

Study reveals most common medical emergencies in schools

2025-07-01
The three most common reasons schools called emergency medical services (EMS) were for neurological crises such as seizures, psychiatric conditions or substance abuse, and trauma related injuries, according to data from the national EMS registry analyzed by researchers from Ann & Robert H. Lurie Children’s Hospital of Chicago. During the study period (2018-2022), school-based medical emergencies constituted 11 percent of EMS encounters for children and two-thirds resulted in transport to the hospital. Findings, published in Pediatrics, can help schools prioritize training so staff can respond even before EMS arrival. “While many schools have taken ...
