Although a very promising solution for capturing solar energy, perovskite solar cells contain lead, which is toxic to the environment and a serious health hazard. EPFL scientists have now found a very elegant and efficient solution by adding a transparent phosphate salt that doesn't interfere with light-conversion efficiency while preventing lead from seeping into the soil in cases of solar panel failure.

The new scientific statement acknowledges the importance of primary care in the system of care for patients with stroke, summarizing the available literature and providing a roadmap for holistic, goal-directed and patient-centered care.

Young children with pneumonia in Bangladesh frequently do not respond to common antibiotics, often resulting in death.

The psychological toll of losing a job due to COVID-19 caused many young hotel and restaurant workers to consider changing careers, according to a new study. Laid-off and fully furloughed hospitality employees reported being financially strained, depressed, socially isolated and panic stricken over the pandemic's effects, leading to increased intention to leave the industry. The intention to leave was particularly strong among women and younger workers. Furloughed workers reported somewhat less distress than laid-off workers.

New study finds that stakeholders' sentiment toward a new CEO has a stronger effect on post succession performance than the CEO's previous experience and fit and this is more critical for new external CEOs

In 2015, massive biomass burning events occurred in Equatorial Asia which released a large amount of carbon into the atmosphere, whose signals were captured by in-situ high-precision measurements onboard commercial passenger aircraft and a cargo ship. A simulation-based analysis with those observations estimated the fire-induced carbon emissions to be 273 Tg C for September - October 2015.

Most of the heart and immunologic problems seen in children with multisystem inflammatory syndrome (MIS-C)--a condition linked to COVID--were gone within a few months, Columbia researchers have found.

A new study conducted in the United Arab Emirates investigates whether asking early adolescents to evaluate the food choices of peers triggers deliberative thinking that improves their own food selection, even when the peers' food choices are unhealthy. The findings suggest that incorporating evaluations of the healthiness of others' food choices can be a tool to fight unhealthy eating lifestyles.

A new study tested whether teens' secure, supportive family relationships at age 14 related to their ability to provide their friends with empathic support across adolescence and into early adulthood. Findings indicate that secure attachment (reflecting on close relationships in an emotionally balanced, coherent, and valuing way) predicts teens' ability to provide empathic support to their close friends.

Scientists have long known that while listening to a sequence of sounds, people often perceive a rhythm, even when the sounds are identical and equally spaced. One regularity that was discovered over 100 years ago is the Iambic-Trochaic Law: when every other sound is loud, we tend to hear groups of two sounds with an initial beat. When every other sound is long, we hear groups of two sounds with a final beat. But why does our rhythm perception work this way?

POSTECH-Korea University joint research team develops a radiative cooling material that is transparent under direct sunlight.

Some sea slugs take up chloroplasts from the algae that they consume into their cells. These chloroplasts retain their ability to perform photosynthetic activity within the animal cells for several months, and thus provide them with photosynthesis-derived nutrition. A team of researchers at the National Institute for Basic Biology (NIBB), in addition to collaborators from seven other Japanese institutions, have published the genome of the sea slug, Plakobranchus ocellatus type black, in eLife.

University of Otago scientists have opened the door to improved treatment of brain dysfunction which causes psychosis.

Researchers look into methods to reduce the early mortality in those with serious mental illnesses.

A higher intake of ultra-processed food is associated with higher risk of inflammatory bowel disease (IBD), finds a study published by The BMJ today.

Statins are associated with a small increased risk of side effects in patients without a history of heart disease, but these effects are mild compared with the potential benefits of treatment in preventing major cardiovascular events, say researchers in The BMJ today.

People with learning disabilities with covid-19 are five times more likely to be admitted to hospital and eight times more likely to die compared with the general population of England, finds a study published by The BMJ today.

Researchers at UC San Francisco have successfully developed a "speech neuroprosthesis" that has enabled a man with severe paralysis to communicate in sentences, translating signals from his brain to the vocal tract directly into words that appear as text on a screen.

Syracuse Earth and environmental sciences professors explain why naming new species may be a never-ending journey

The physician-scientist workforce doing kidney research in the United States is increasingly made up of women and international medical graduates. However, this workforce is older, declining in relative number, and is less overwhelmingly focused on basic rather than clinical science.
