Phys.org / How longer exciton lifetimes could ease efficiency trade-off in organic solar cells
Although the efficiency of organic solar cells has now risen to more than 20%, there are physical limits that make it difficult to further increase their performance. A research team from Linköping University in Sweden, the ...
Phys.org / Artificial DNA tiles could deliver drugs and monitor neurons non-disruptively
Living cells constantly exchange ions (i.e., charged particles) via the thin barrier that surrounds their interior, known as the outer membrane. Neuroscientists and medical researchers have long been trying to devise effective ...
Phys.org / Language-based screeners may miss kids who struggle to read due to visual-processing issues
Reading difficulties, like dyslexia, are common and often affect achievement and outcomes during school and later in life. A new study, published in Current Biology, reports that current methods used to test for reading disabilities ...
Medical Xpress / Exposure to bright evening light linked to higher risk of age-related eye disease
Every sunrise and sunset sends the body a signal, keeping the circadian clock running on a roughly 24-hour cycle. This clock evolved so organisms could adapt to Earth's daily rotation, syncing their biology to the pattern ...
Phys.org / Why female guppies prefer rare males and how this might shape evolution
When it comes to choosing a partner, some species prefer males that stand out from the crowd. Evolutionary biologists call the resulting process negative frequency-dependent selection. It means that a male has a huge mating ...
Phys.org / Mathematical modeling helps advance use of magnetic particles in targeted drug-delivery systems
A Florida State University computational scientist is paving the way for future medical breakthroughs by developing mathematical models and simulations to predict the behavior of a unique drug-delivery method, which aims ...
Phys.org / Fair Workweek laws improve work schedules without cutting pay or benefits, according to research
A study examining Fair Workweek laws across five major U.S. jurisdictions finds that labor regulations have made work schedules more predictable for service-sector workers, without triggering wage cuts or benefit reductions. ...
Phys.org / Contagious cancer likely crossed an ocean, triggering severe outbreak in Pacific Northwest clams
Researchers have identified a severe outbreak of a rare contagious cancer in soft-shell clams in Washington state's Puget Sound and found evidence that the disease was recently introduced to the Pacific Northwest from Atlantic ...
Medical Xpress / New oral GLP-1 drug delivers up to 12% weight loss in 36 weeks
A new strategy for delivering GLP-1 drugs to patients with obesity or who were overweight resulted in up to a 12% reduction in body weight after 36 weeks, according to a randomized phase II clinical trial published in Nature ...
Phys.org / Drifting tuna gear creates risks for wildlife in protected marine areas
An international study co-authored by a University of Hawaiʻi at Mānoa researcher has found that drifting devices used by the global tuna fishing industry are entering marine protected areas around the world, creating potential ...
Medical Xpress / AI system detects sudden cardiac death risk, identifying thousands more patients annually
Each year in the U.S., more than 300,000 people die from sudden cardiac arrest, a condition in which the heart's electrical system malfunctions without warning. The medical emergency can kill both high-risk older adults and ...
Phys.org / How mitochondria build their protein factories could help explain energy‑linked disease
In a study published in Nature Communications, researchers at Karolinska Institutet have mapped key steps in the assembly of the mitochondrial ribosome, offering new clues to how defects in this process can lead to disease.
