Tech Xplore / Perovskite solar cells reach 26.61% certified efficiency with cesium-doping strategy
Solar cells, devices that convert sunlight into electricity, are now widely used in many countries. While most existing solar cells are based on silicon, energy engineers have been working on other devices made of so-called ...
Phys.org / Gene-sharing view challenged as bacteria shown to police DNA exchange
A new study finds that bacteria can actively block the transfer of beneficial genes to neighboring cells, using specialized proteins to specifically destroy shared DNA before it spreads. This challenges the long-held view ...
Medical Xpress / Astrocytes reveal fragile X pathway tied to seizures and synapse problems
Fragile X syndrome (FXS) is an inherited genetic developmental condition that strongly impacts brain development. Despite the syndrome stemming from an altered genetic code for the single protein fragile X messenger ribonucleoprotein ...
Phys.org / Quantum simulations that bypass resolution limits offer insights into high-temperature superconductivity
A new method developed at LMU overcomes fundamental resolution limits and may provide insights into high-temperature superconductivity. Physicist Dr. Sebastian Paeckel has developed a method that can be used to calculate ...
Phys.org / Missing link in evolution of ancient fish found in 150-year-old museum specimen
A new species of coelacanth has been identified from a 150-year-old fossil housed at London's Natural History Museum. Former University of Portsmouth paleontology student Jack L. Norton located the coelacanth, which provides ...
Phys.org / Why more gut and soil microbes could make ecosystems easier to predict
Much of the beauty—and challenge—of biology lies in its complexity. That's especially true in the microbial world, where hundreds or thousands of different bacterial species may co-exist in a patch of soil or in a section ...
Phys.org / Machine learning helps detect roars from lion collars without recording actual audio
Roaring over long distances is a key behavior of lions. They communicate within prides as well as with other animals using distinct sequences of moans and grunts. Scientists from the GAIA Initiative have now published a machine ...
Medical Xpress / Conversational AI uses trusted medical protocols to help people decide when to seek care
A new type of chatbot could reliably help people decide what to do about their symptoms—and do so based on guidance that is both medically sound and easy to understand. The chatbot could help reduce unnecessary hospital visits ...
Phys.org / Black grouse eye test reveals best flags to protect birds from fatal cables
There is a silent killer lurking in the French Alps: ski lift cables. Over the last 60 years, the wires have accounted for almost 600 recorded landfowl deaths in the region. Black grouse (Lyrurus tetrix) account for ~70% ...
Phys.org / Engineered soil bacterial protein kills colorectal cancer cells by targeting their mitochondria
Researchers at Umeå University have turned a protein from soil bacteria into a potential new weapon against colorectal cancer. Their study published in Cell Death Discovery shows how an engineered bacterial protein can trigger ...
Phys.org / From air to tea: New sensor reveals invisible pollution in minutes
Fine particulate matter in the air or nanoparticles in water—a remarkable new technology developed at TU Wien makes it possible to detect tiny amounts of a wide range of substances in a very short time.
Tech Xplore / Excuse me, is that solar panel pointing in the right direction?
On a bright morning, graduate student Jeremy Klotz and professor Shree Nayar walked through upper Manhattan with a tall tripod and a camera that takes 360-degree images. Their route took them to bike docking stations, which ...
