About The Study: Although the global age-standardized burden rates of subarachnoid hemorrhage (SAH) more than halved over the last 3 decades, SAH remained one of the most common cardiovascular and neurological causes of death and disabilities in the world, with increasing absolute case numbers. These findings suggest evidence for the potential health benefits of proactive public health planning and resource allocation toward the prevention of SAH. Nontraumatic SAH represents the third most common stroke type after ischemic stroke and intracerebral hemorrhage, accounting for 5% to ...

New research published in Communications Biology has uncovered the earliest known use of the medicinal and psychoactive plant Peganum harmala, commonly known as Syrian rue or harmal, in fumigation practices and inhaled as smoke. The findings offer unprecedented insight into early Arabian therapeutic and sensorial practices, revealing that native plants were already being deliberately used for their bioactive and psychoactive properties nearly 2,700 years ago. Led by Dr. Barbara Huber (Max Planck Institute of Geoanthropology) and Professor ...

Wouldn’t it be amazing if we could continuously monitor the molecular state of our body? Consider the solutions that could enable, from optimized drug delivery to early detection of deadly diseases like cancer. For the last two decades, research has aimed to make this a reality by developing devices that measure a chemical or biological reaction in our bodies and send their measurements as a signal readable from outside the body. These devices, called biosensors, can now spot tiny molecules like drugs in real time, but they work only briefly. There is still no single reliable biosensor that can monitor many different substances in our bodies over long stretches. To address ...

A new international study led by researchers at Tulane University shows that the El Niño and La Niña climate patterns affect nearly half of the world's mangrove forests, underscoring the vulnerability of these vital coastal ecosystems to climatic shifts. Mangroves are shrubs or trees that grow in dense thickets mainly in coastal saline or brackish water. The research, published in Nature Geoscience, is based on nearly two decades of satellite data from 2001 to 2020 and is the first study to demonstrate global-scale patterns in how El Niño-Southern Oscillation (ENSO) influences ...

Improving energy conversion efficiency in power electronics is vital for a sustainable society, with wide-bandgap semiconductors like GaN and SiC power devices offering advantages due to their high-frequency capabilities. However, energy losses in passive components at high frequencies hinder efficiency and miniaturization. This underscores the need for advanced soft magnetic materials with lower energy losses. In a recent study published in Communications Materials, a research team led by Professor Mutsuko Hatano from the ...

While moderate touristification can bring economic benefits to cities, overtourism has adverse social effects on residents and visitors. To prevent this, it is necessary to understand the disrupted balance between tourist accommodations and residential housing. Junior Associate Professor Haruka Kato investigated the spatial patterns and geographic characteristics of tourism-accommodation hotspots in proximity to tourist locations in Kyoto, one of the most famous tourist cities in the world. In this study, the tourism-accommodation intensity index was calculated using the ratio of the number of accommodation rooms to that of households. The results revealed that ...

Plants require phosphorus to grow and survive. In environments with low levels of available soil phosphorus, plants need to adjust to stay alive. The pincushion hakea is a large woody, evergreen shrub native to southwestern Australia, an area that has amazingly low levels of soil phosphorus. This plant has adapted to these conditions by forming cluster roots—a large number of smaller rootlets extending from the root axis that resemble a bottlebrush—to extract the small amount of phosphorus in the soil. Cluster roots help plants in low-nutrient soils by increasing the amount of root surface area in contact with the soil, improving ...

A survey on larvae of Japanese wasps revealed that not only is their diet more diverse than previously thought, it also showed that wild colonies prey on more species of vertebrates than had been reported in the past. The Kobe University study highlights the potential for management practices that are sustainable both ecologically and culturally. The wasp species Vespula shidai has long been reared for its edible larvae, a delicacy in central Japan. The rural woodlands of Japan which these wasps inhabit are areas of high biodiversity. Though this ...

Many years ago, I got to spend some time in Ngorongoro Crater, a unique place in Africa where immense herds of animals are being watched by equally immense crowds of 4x4-riding tourists, and traffic jams of all kinds are frequent. On my last evening there, a local guide told me at a campfire that some buffalo in the crater had figured out the meaning of car turn signals and used that understanding to get out of the way of turning Jeeps and Land Rovers. I never had a chance to return to the crater and still don’t know if that story was true, but it got me interested in animals’ perception of – and interactions with – human-made vehicles. Of course, the most ...

Over the past decade, much research has focused on the connection between skeletal muscle health and cognitive disorders. Scientists have found that sarcopenia, a geriatric syndrome characterized by progressive loss of skeletal muscle mass and function, appears to be strongly associated with an elevated risk of dementia. The complex relationship between our muscles and brain health represents a promising frontier in preventive medicine, particularly as global populations continue to age.   However, to date, most studies on the link between muscle health and dementia have predominantly targeted elderly populations or individuals already diagnosed with cognitive impairment. ...

Intracellular protein trafficking and secretion of proteins into the extracellular environment are sequential and tightly regulated processes in eukaryotic cells. Conventionally, proteins that are bound for secretion harbor an N-terminal signal peptide that guides their movement from the endoplasmic reticulum (ER) and Golgi apparatus to the exterior of the cell. However, some proteins can bypass this system using unconventional mechanisms, including direct translocation across the plasma membrane, transporter-mediated ...

A group of fossils of elasmosaurs – some of the most famous in North America – have just been formally identified as belonging to a “very odd” new genus of the sea monster, unlike any previously known. Long-necked and measuring in at 12 metres, Traskasaura sandrae – as it is officially named today in this new study – possessed heavy, sharp, robust teeth, ideal for crushing. Findings, published in the peer-reviewed Journal of Systematic Palaeontology, highlight Traskasaura as having a strange mix of primitive and derived traits unlike any other elasmosaur. Its unique suite ...

Australia needs to urgently prioritise state and national conservation policies according to a new study, with the findings warning more than 220 critically endangered species are at risk of being lost due to their small distributions coupled with uneven protections.  In the first known study of its kind, the team led by Griffith University, assessed how much of each species’ habitat in Australia was outside protected areas and considered to have agricultural capability, potentially elevating risk of conversion.  They ...

SAN DIEGO (May 22, 2025) – A new scientific study led by San Diego Zoo Wildlife Alliance researchers sheds light on the social dynamics that drive the continued consumption of bear bile in Việt Nam, revealing that gift-giving among close social networks plays a crucial role in sustaining demand. The findings suggest that conservation efforts could be more effective if they focus on shifting behaviors within influential social groups rather than broad public awareness campaigns.  Bear bile, extracted from the gallbladders of Asiatic black bears and sun ...

Heat waves destroy crops, drive wildfires, and kill humans and wildlife, but these extreme weather events aren’t just limited to land. Large bodies of water can also be hit by heat waves that linger for weeks, months and sometimes years—much like “The Blob,” a sprawling hot spot off the U.S. West Coast that wreaked havoc on Pacific Ocean ecosystems from 2013 to 2016. New University of Maryland-led research reveals that the Chesapeake Bay has seen “significant increases” in annual marine heat waves, defined in the study as “prolonged periods of anomalously warm water.” Published in the journal Estuaries and Coasts, the study leveraged ...

NEW YORK, NY (May 22, 2025)--When Columbia neurologist and scientist Neil Shneider speaks to his ALS patients who volunteer for experimental therapies, he’s unwaveringly honest. “Patients always ask me, “What can I hope to get out of this?” Shneider says. “And I always say, in most clinical trials, our hope is that we can slow the disease or maybe even halt progression.”  So it was a big surprise when some of the patients treated with an experimental drug—a therapy that emerged from Shneider’s research efforts—showed improvements. “When testing new drugs for ALS, we do not expect to ...

As we get older, our bodies stop performing as they once did. We aren’t as strong as we once were, we don’t see as well as we used to and we start becoming less mobile. These changes inevitably lead to almost a third of people over the age 65 falling each year, resulting in injuries and occasionally death. In the United States alone, it costs the healthcare system billions of dollars annually. However, while aging is a certainty, falling may be preventable. ‘One big challenge is that small balance impairments can go unnoticed until someone actually falls. So, we wanted to ask: Can we detect these impairments before someone gets hurt?’ explains Jiaen ...

Images   A newly discovered silicone variant is a semiconductor, University of Michigan researchers have discovered—upending assumptions that the material class is exclusively insulating.  "The material opens up the opportunity for new types of flat panel displays, flexible photovoltaics, wearable sensors or even clothing that can display different patterns or images," said Richard Laine, U-M professor of materials science and engineering and macromolecular science and engineering and corresponding author ...

Tropical cyclones, including storms below hurricane and typhoon strength, were associated with a sharp rise in infant mortality in low- and middle-income countries during the first two decades of this century, according to new research published in Science Advances. The findings point to a critical need for stronger disaster response and child health protections in vulnerable regions, especially as climate change increases the frequency and severity of these storms. Infants in these regions exposed to tropical cyclones before they were born ...

Roughly 10 percent of the U.S. population is afflicted with major depressive disorder at any given time, and up to 20 percent will exhibit MDD symptoms over their lifetimes. Yet despite its prevalence, methods to treat MDD often fall short for a not-insignificant portion of the population. Antidepressants—the standard of treatment—don’t work for 30 percent with MDD. When infused at a low dose ketamine shows remarkable efficacy as a rapidly acting antidepressant, with effects observed within hours even in patients who have been resistant to other ...

University of Illinois Physics Professor Paul Kwiat and members of his research group have developed a revolutionary new tool for precision measurement at the nanometer scale in scenarios where background noise and optical loss from the sample are present. This new optical interferometry technology leverages the quantum properties of light—specifically, extreme color entanglement—to enable faster and more precise measurements than widely used classical and quantum techniques can achieve. Colin ...
