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 / Powerhouses for fake meat: Muscle protein can now be grown in chloroplasts of lettuce and tobacco plants
Livestock farming requires valuable land to grow fodder, uses vast amounts of freshwater and contributes to global warming through methane and nitrous oxide emissions. And, for many consumers it is important to prevent animal ...
Phys.org / Newly identified C/EBPγ protein links cancer cell plasticity and DNA repair
A research team has identified the transcription factor C/EBPγ as a novel regulator that simultaneously promotes epithelial-mesenchymal transition (EMT) and DNA double-strand break repair in lung adenocarcinoma cells. The ...
Phys.org / Antenna-like cell appendage may help turtle embryos sense sex-deciding nest temperatures
When most baby turtles hatch, their sex depends on the temperature of the sand or soil where their mother laid her eggs. Warm incubation produces females, while cool nests produce males.
Phys.org / Milky Way-like simulation reveals how central galactic structures grow together
Understanding the formation and evolution of the centers of galaxies is one of the most intriguing challenges in astrophysics. The new study aims to unveil the physical processes that led to the formation of two striking ...
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 / Researchers demonstrate first fully solution-processed solid-state polariton laser
Researchers have demonstrated a solid-state organic laser microcavity fabricated entirely by solution processing. The device operates in the strong light–matter coupling regime, where light and matter form hybrid states called ...
Phys.org / From mountain peaks to microclimates, new maps bring satellite big data down to Earth
Zooming from her office, Michigan State University researcher Kelly Kapsar showed satellite images from across the United States. In some, different colors revealed the precise heights of the forested ridges in the Sierra ...
Phys.org / Charting the galaxy: Milky Way Mapper survey releases latest all-sky spectra
The Sloan Digital Sky Survey V (SDSS-V) has announced its 20th public data release (DR20), delivering a dramatic expansion of the Milky Way Mapper (MWM) scientific survey—the most detailed spectroscopic map yet assembled ...
Tech Xplore / 'Chameleon' chip adapts to changing data speeds, cutting prediction errors by up to 40-fold
AI semiconductors are becoming more programmable. KAIST researchers have developed a device whose response characteristics can be programmed to process data that changes at different speeds. The technology reduced prediction ...
Phys.org / Hidden hormone–habitat relationship revealed in reef fish
In the animal kingdom, only those that adapt to their environment survive. This adaptation takes a wide range of forms, from invisible internal shifts in gene expression to dramatic anatomical changes, such as tadpoles growing ...
Phys.org / Observing key material properties atom by atom for the first time
Many material properties depend on how electrons are arranged inside a material. Their distribution determines, for example, whether a material conducts electricity or displays magnetic behavior. Understanding how electrons ...
