Tech Xplore / Two molecules work together to seal microscopic gaps in perovskite solar cells
A research team has developed a dual-molecule passivation technology that simultaneously improves the efficiency and stability of inverted perovskite solar cells. The research is published in the journal ACS Applied Materials ...
Phys.org / Saturn encounter may have set distant centaur on path to becoming a comet
More than 3 billion miles (4.8 billion kilometers) from Earth, an ancient icy object is slowly awakening. As it drifts inward through the solar system, the frozen body known as Centaur 450P/LONEOS has begun releasing gas ...
Medical Xpress / Runner's high study finds cannabis-like signaling molecules rise over extreme distances
A marathon, 100 kilometers (62 miles) or even 230 kilometers (143 miles) in a single effort: Anyone running such distances puts enormous strain on their body. At the same time, levels of the body's own cannabis-like signaling ...
Phys.org / 'Empty nest' can trigger loneliness and loss in older parents, study finds
Older parents can experience loneliness, emotional distress and a loss of purpose when their children leave home, according to a new pilot study by the University of Hertfordshire.
Phys.org / First measurement of low-energy solar neutrinos scattering off electrons
Every second, tens of billions of neutrinos produced by nuclear fusion in the sun pass through every square centimeter of Earth—and through our bodies—almost without interacting. Although they are among the most abundant ...
Tech Xplore / Adding a 'doubt detector' helps AI optimize experiments with 40% fewer tests
Modern computational tools let scientists explore huge numbers of possible molecules, materials and chemical reactions. But testing every combination in the lab is slow and costly. So how do researchers choose the best "recipe" ...
Phys.org / LEDs let archaeologists see the past in a new light
An archaeological excavation is a little like eating a layered cake: Once you have removed a layer, you cannot put it back. The problem becomes even trickier if two layers look almost exactly the same. Researchers from Aarhus ...
Tech Xplore / Bleach and salt water boost power in grid batteries, moving from side reaction to center stage
To create large-scale grid energy storage that is more affordable, powerful and safe, researchers at the Department of Energy's (DOE) Oak Ridge National Laboratory (ORNL) decided to let a strong side reaction step into the ...
Phys.org / Why lower-class workers are less likely to negotiate for higher pay—and how it could cost some nearly $800,000
Michele Gelfand has studied and taught negotiation for years. A professor of organizational behavior at Stanford Graduate School of Business, she sees negotiation as a skill that is imperative for everyone to learn. "It's ...
Phys.org / El Niño could be strongest in decades, UN warns
El Niño is forecast to be the strongest since comparable records began four decades ago, the United Nations' climate agency warned Thursday, with the UN chief saying the world was in the "danger zone of extreme weather."
Phys.org / Forest floor to treetops, cameras reveal Congo Basin's hidden wildlife
The Democratic Republic of Congo's (DRC) tropical forests stretch across an extraordinary landscape of rivers, wetlands, savannas and towering trees. But in a forest this vast, biodiversity doesn't exist on a single plane. ...
Medical Xpress / Breathing without brakes: An unexpected cause of Rett syndrome symptoms
Hyperventilating. Breath-holding until they turn blue. This abnormal breathing is frequent and disturbing in people with Rett syndrome, a rare genetic disease. Now University of Connecticut researchers report in Current Biology ...
