Researchers used social media network models to analyze fish populations in the Mediterranean Sea, finding that warming seas have significant and widespread effects on biodiversity. The study suggests that winter warming may lead to changes in fish communities, potentially causing some species to disappear from certain areas.
Researchers have developed a new design method for highly compact deployable structures inspired by the folding of earwig wings. The method has potential applications across various fields, including engineering, architecture, and daily-use products.
Nursing homes face extreme challenges in the COVID-19 pandemic, but partnerships with health systems can support better staffing, virus testing, and data sharing. This collaboration can facilitate reduced hospital readmissions, improved safety of transitions of care, and ultimately improve care for vulnerable populations.
A yearlong trial enrolls patients with COVID-19 to evaluate ramipril's ability to prevent worsening of the illness. Experts investigate ACE inhibitors' potential to reduce severity by regulating the renin-angiotensin-aldosterone system.
Researchers at Lehigh University have identified a causal link between high-level noise exposure and low birth weight. The study found that mothers living close to Newark Liberty International Airport, exposed to noise levels over 55 dB threshold, had a 22% increased risk of having a low birth weight baby.
A nine-year longitudinal study found that family caregivers did not experience significantly greater inflammation levels compared to non-caregivers, challenging past research findings. The study suggests that caregiving may have minimal effects on physical health for most caregivers.
Researchers found that mice with a common genetic mutation in autism spectrum disorder had delayed and weaker blood vessel responses, which led to neuronal dysfunction and autistic traits. The study suggests that problems with blood vessels begin early in life and can contribute to the development of autism.
A new NIH study suggests that deactivating certain genes in the human genome may play a role in controlling the differentiation of stem cells into neurons. The research found that these genes, which were once thought to be inactive 'junk DNA', may help regulate the maturation process of stem cells, leading to improved understanding of ...
A research team at POSTECH developed a new catalyst that improves the durability of automotive fuel cells when shut down. The Pt/HxWO3 catalyst promotes hydrogen oxidation and selectively suppresses oxygen reduction reactions, solving the corrosion issue.
A new PET radiotracer has been proven safe and effective in imaging malignant brain tumors with high sensitivity. The radiotracer targets αvβ3 integrin, which is overexpressed in glioblastomas, allowing for superior visualization of tumors.
A multidisciplinary team from UTMB has uncovered a new mechanism for designing antiviral drugs for dengue virus. The co-crystal structure of the dengue capsid protein in complex with an inhibitor provides atomic details of how the inhibitor blocks viral infection.
Researchers analyze Comet ATLAS's carbonaceous particles to determine the age of other comets. The study suggests that long-period comets with high carbon content have spent less time in the Solar System.
Scientists create geometrical drawing method and software to design fan-like structures based on earwig wing folding. The method was used to recreate a Paleozoic earwig's wing folding pattern, shedding light on evolutionary pathways.
A BU researcher outlines common media failures in reporting coronavirus research, including incomplete and biased information. The author recommends greater caution and detail in science communication to avoid harm and maintain trust.
UT Dallas researchers are using the Minecraft mod Polycraft World to simulate dynamic and unexpected events to train AI systems. They aim to create artificial intelligence agents that can respond appropriately in novel scenarios, such as changing weather or unfamiliar terrain.
A new insect detection system using tiny chicken backpacks with wearable sensors has been developed to detect blood-feeding livestock mites. The technology, nicknamed 'Fitbits for chickens,' can help farmers identify infestations and improve poultry welfare.
A combined analysis of 23 studies found that episodes of delirium are a risk factor for long-term cognitive decline. The research suggests that individuals who experience delirium may be more likely to develop dementia and other cognitive impairments over time.
Researchers have developed a highly efficient solar-flow battery that can store and redeliver renewable electricity from the sun. The device achieved a record efficiency of 20 percent conversion, outperforming previous records by 40%. This breakthrough could potentially yield a new way to harness, store and use the sun's energy for sol...
