Researchers from Aalborg University have developed a heat-resistant device made of tungsten and alumina layers that can absorb sunlight across a broad spectrum, enabling more efficient energy conversion. The device can operate at high temperatures and absorb light from UV to near-infrared wavelengths.
Scientists discovered 15 genome sites linked to depression in European ancestry, regulating gene expression and new neuron birth. Using crowd-sourced data, they detected weak genetic signals associated with depression, supporting a novel approach to complement traditional methods.
NASA satellites monitored Typhoon Nida's intense rainfall, reaching rates of over 3.5 inches per hour, as it approached southeastern China. The storm's height reached over 10.5 miles in some areas, posing a threat to Hong Kong.
A genomic study using a novel method has identified 15 regions of the genome linked to depression in European ancestry individuals. The study analyzed data from over 300,000 individuals and found sites associated with risk genes, including those involved in brain development.
Researchers found an association between low physical activity and a higher risk for dementia in older individuals, with regular exercise potentially leading to higher brain volumes and reduced dementia risk. The protective effect was strongest in people aged 75 and older.
Experts say psychology is key to understanding road safety and autonomous vehicle success. The event aims to reduce road trauma by sharing the latest in road safety research.
A French team of researchers discovered that acquired antibiotic-resistant plasmids rarely drop their resistant genes even when selection pressure is absent. The study, published in Antimicrobial Agents and Chemotherapy, focused on extended-spectrum cephalosporin resistance.
A large study found that high animal protein intake, particularly from red meats, was associated with a higher mortality rate. In contrast, high plant protein intake was linked to a lower risk of death. The study analyzed data from over 170,000 participants and found that the association disappeared in those with a healthy lifestyle.
Drone-launched fireballs can aid in wildfire suppression and ignite prescribed burns for grassland restoration. High-intensity fires are effective in killing invasive shrubs, promoting fire-adapted grasses.
Researchers have developed iron catalysts that can diversify chiral amino acids into 21 different structures while preserving their handedness. This technology allows for the creation of modified peptides or entirely new structures, expanding the pool of unnatural chiral amino acids available to researchers.
Researchers found that early antiretroviral therapy significantly reduces total HIV DNA levels in the body, which may predict time to viral load rebound after treatment cessation. The study suggests that people with a smaller HIV reservoir size have a greater chance of achieving long-term HIV remission.
A new review explores potential antioxidant approaches for Alzheimer's, Parkinson's, and other neurodegenerative diseases. Certain compounds targeting oxidative stress pathways, such as Nrf2, are being investigated.
A study by Loyola Medicine found that excessive alcohol consumption is associated with lower nitric oxide levels in the lungs, which helps protect against certain bacteria. The researchers suggest that lung doctors should consider the impact of alcohol on nitric oxide levels when interpreting test results.
Researchers at Binghamton University are developing a smartwatch application to enhance communication systems in nursing homes. The proposed design integrates existing safety systems, providing alerts to users. Studies show that using this system can reduce staff response time to alarms and improve patient safety.
Mathematical biologist Samuel Scarpino and colleagues found that replacing sick individuals with healthy ones can accelerate the spread of infection for certain diseases. The study analyzed data from two diseases, influenza and dengue, and revealed a stronger correlation between human exchange and outbreak acceleration in influenza.
Researchers develop mathematical models to mimic bird navigation in turbulent thermals, revealing key environmental cues like vertical wind acceleration and torque. The study aims to guide the design of energy-efficient autonomous gliders.
A recent study on 'The Biggest Loser' television series found that participants regained much of the weight they lost, with suppressed metabolism. Experts say a 5-15% weight loss is unlikely to lead to such large effects on metabolism and emphasize the importance of long-term lifestyle changes.
A recent study by ETH Zurich researchers found that opposing mountain ranges will experience different water balance changes due to climate change. The Juncal region in Chile is expected to become even drier, while the upper Langtang valley in Nepal may see increased water discharge due to glacier melt and increased rainfall.
Researchers found that adding anti-PCSK9 antibodies to existing treatments can significantly reduce LDL cholesterol levels in patients. The studies demonstrated a reduction in LDL cholesterol and achieved high response rates for both alirocumab and evolocumab.
Haptics researchers at Northwestern University have discovered that ultrasonic vibrations cause fingers to bounce on touchscreens, reducing friction. This phenomenon is caused by the air trapped between the finger and screen compressing and acting like a spring, allowing the finger to fall onto a cushion of air instead of the screen.
Researchers at George Washington University discovered a connection between CD4 T-cell exhaustion and CD8 T-cell exhaustion in chronic toxoplasmosis. Regulating CD4 T-cells with Blimp-1 protein expression can reverse CD8 T-cell dysfunction, leading to improved pathogen control.
Three studies published in JAACAP report that combining standard ADHD medications improves clinical outcomes, including reduced symptoms and enhanced cognitive functions. The combined therapy showed a higher rate of good clinical response and improved brain activity patterns compared to single drug therapies.
A study published in JAMA Internal Medicine found that consuming more plant-based protein was associated with a lower risk of death from all causes and cardiovascular disease. The researchers observed significant health benefits when substituting animal protein with plant protein, particularly from processed red meat.
