Phys.org / Interlocking molecular propellers create stable 'islands' in artificial lipid membranes
Cells are enclosed by a cell membrane, a sophisticated structure mainly made of lipids that is vital for fundamental biological processes. Artificial lipid membranes have many practical applications, such as drug delivery, ...
Tech Xplore / Paste-and-laser strategy helps TOPCon solar cells reach 26.31% certified efficiency
Improving the efficiency of solar cells is key to reducing the cost of solar power. Now, scientists have developed a new synergistic metallization strategy for tunnel oxide passivated contact (TOPCon) solar cells. The approach ...
Medical Xpress / Bacterial supplements may boost female fertility
As women get older, their uterine environment changes. This includes a decrease in a beneficial bacterium called Lactobacillus gasseri, which may make conception—whether natural or via in vitro fertilization—difficult. In ...
Medical Xpress / First complete marmoset genome will enable research on Alzheimer's and neurodegenerative diseases
To study complex diseases like Alzheimer's, scientists and clinicians analyze how genes change and malfunction in other species. Marmosets, a species of tiny monkey from South America, have become an important animal model ...
Medical Xpress / Why laughter can trigger sudden muscle weakness in people with narcolepsy
Narcolepsy is a chronic neurological condition characterized by disruptions in the regulation of sleep-wake cycles. People with this condition often experience extreme sleepiness during the day and, in some cases, a sudden ...
Phys.org / Were there tiny dinosaurs? New study explores one of evolution's biggest mysteries
Dinosaurs are famous for being big, from the towering Tyrannosaurus rex to the colossal Apatosaurus. But a new study published today in the journal Evolution by scientists at the American Museum of Natural History and Princeton ...
Phys.org / A temperature dial for more realistic quantum simulations
Scientists from Rice University in the U.S. have developed a way to precisely tune the temperature inside a trapped-ion simulator. The breakthrough means they will be able to run quantum simulations at precise temperatures ...
Medical Xpress / Map of tonsil's genetic 'spaghetti' yields insights into immunity
About 2 meters (6.6 feet) of genetic material must fit into the nucleus of each of most of our trillions of cells, coiling and winding to form what looks like a tangled mess. But when genes are used, how they are used and ...
Phys.org / Asteroid Nysa's rare three-lobed structure challenges formation models
Named for the mythical valley where the god Dionysus was raised in secret by nymphs, the asteroid 44 Nysa inhabits the asteroid belt between Mars and Jupiter. Through observations by the Hubble Space Telescope, astronomers ...
Phys.org / Ant teams beat gravity-based puzzle solvers
Ants live in highly organized colonies and cooperate daily to tackle a wide range of problems. Their striking group behaviors have fascinated biologists for centuries and even inspired the development of various artificial ...
Medical Xpress / New therapy eliminates gum disease bacterium while preserving beneficial oral microbes
Researchers at Nagoya University in Japan have created an innovative treatment for periodontitis that targets and eliminates harmful bacteria while preserving beneficial oral microbes essential for health. The findings were ...
Phys.org / One of the world's only two complete dodo skulls reveals new clues about the extinct bird
Only two complete dodo skulls are known to exist anywhere in the world: one at the Natural History Museum Denmark and one at the Oxford University Museum of Natural History. The specimen housed in Copenhagen has been preserved ...
