Phys.org / Scientists find more active black holes in dwarf and Milky Way-sized galaxies by cutting through glare of star formation
Astronomers have completed the most comprehensive census of active galactic nuclei (AGN) to date, providing the clearest picture yet of the probability that galaxies of different sizes host active black holes.
Medical Xpress / Control valve discovered in gut's plumbing system may hold answers to constipation and diarrhea
Although constipation and diarrhea may seem like opposite problems, they both hinge on the same underlying issue: how much fluid moves into the gut. These common issues affect millions of people in the U.S. each year, yet ...
Phys.org / Replication efforts suggest 'smoking gun' evidence isn't enough to prove quantum computing claims
A group of scientists, including Sergey Frolov, professor of physics at the University of Pittsburgh, and co-authors from Minnesota and Grenoble have undertaken several replication studies centered around topological effects ...
Medical Xpress / Hormone estradiol shapes women's brain responses to threat after trauma, study finds
Women are more than twice as likely as men to develop stress-related conditions such as posttraumatic stress disorder (PTSD), but the biological mechanisms underlying that risk have remained poorly understood. New research ...
Phys.org / A tug-of-war explains a decades-old question about how bacteria swim
Scientists have uncovered a new explanation for how swimming bacteria change direction, providing fresh insight into one of biology's most intensively studied molecular machines.
Phys.org / New method reveals how mutations drive transthyretin amyloidosis and guides precision drug design
An international research team reveals new molecular mechanisms associated with pathogenic mutations in the protein transthyretin that cause transthyretin amyloidosis (ATTR), a group of fatal progressive diseases. The results, ...
Medical Xpress / Origin cells for common malignant brain tumor in young adults uncovered
IDH-mutant glioma, caused by abnormalities in a specific gene (IDH), is the most common malignant brain tumor among young adults under the age of 50. It is a refractory brain cancer that is difficult to treat due to its high ...
Medical Xpress / TB harnesses part of immune defense system to cause infection, study finds
Scientists have made a discovery that helps explain why humans and animals are so susceptible to contracting tuberculosis (TB)—and it involves the bacteria harnessing part of the immune system meant to protect against infection.
Tech Xplore / OLED lighting: Corrugated panel design extends longevity and efficiency
The organic light emitting diodes—known widely as OLEDs—that create vibrant smartphone displays could illuminate rooms, but current designs burn out too quickly at the high brightness needed for room lighting. A new approach ...
Tech Xplore / Coal tailings could solve United States' need for rare earth elements
Rare earth elements are an easy-to-find, hard-to-refine resource critical for everything from magnets and electronics to batteries and catalysts for chemical reactions. Since the 1980s, a race has been on between the United ...
Phys.org / Antiferromagnetic metal exhibits diode-like behavior without external magnetic field
Antiferromagnetic (AF) materials are made up of atoms or molecules with atomic spins that align in antiparallel directions of their neighbors. The magnetism of each individual atom or molecule is canceled out by the one next ...
Medical Xpress / COVID-19 still claims more than 100,000 US lives each year
Centers for Disease Control and Prevention researchers report national estimates of 43.6 million COVID-19-associated illnesses and 101,300 deaths in the US during October 2022 to September 2023, plus 33.0 million illnesses ...
