Global, regional, and national burden of nontraumatic subarachnoid hemorrhage

JAMA Neurology

2025-05-23

(Press-News.org) 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 10% of all strokes.

Earliest use of psychoactive and medicinal plant ‘harmal’ identified in Iron Age Arabia

2025-05-23

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 ...

Nano-scale biosensor lets scientists monitor molecules in real time

2025-05-23

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 ...

Study shows how El Niño and La Niña climate swings threaten mangroves worldwide

2025-05-23

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 ...

Quantum eyes on energy loss: diamond quantum imaging for next-gen power electronics

2025-05-23

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 ...

Kyoto conundrum: More hotels than households exist in ancient capital

2025-05-23

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 ...

Cluster-root secretions improve phosphorus availability in low-phosphorus soil

2025-05-23

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 ...

Hey vespids, what's for dinner? DNA analysis of wasp larvae’s diverse diet

2025-05-23

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 ...

Street smarts: how a hawk learned to use traffic signals to hunt more successfully

2025-05-23

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 ...

Muscle quality may hold clues to early cognitive decline

2025-05-23

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. ...

Autophagy and lysosomal pathways orchestrate unconventional secretion of Parkinson’s disease protein

2025-05-23

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 ...
