Phys.org / Molecular memory: How a mother's age echoes in her offspring's cells
In humans and many other animals, a mother's age can affect the physical and behavioral characteristics of the next generation. Scientists call these changes maternal age effects, and while they are widespread across the ...
Phys.org / Amber fossil reveals firefly relative with unprecedented antennae
Insects rely on a wide range of strategies to sense their surroundings and communicate with their peers. Fireflies (Lampyridae) and some related beetles are known for their ability to produce visible light through chemical ...
Phys.org / Shrews exhibit reversible size changes in their skulls and noses to get through the winter
Scientists had previously observed that some species of shrews undergo a form of biological plasticity in which their bodies, skulls, brains and some organs shrink in the winter, then regrow in the spring. Now, a new study ...
Phys.org / Iron hydride enters an exotic state of matter under Earth's inner-core conditions
Earth's inner core, composed primarily of iron with a small percentage of light elements, may enter a superionic state at extreme pressure and temperature, according to experimental results from researchers at Science Tokyo. ...
Phys.org / China's solar push linked to bird diversity losses across 2,344 counties
The global push for solar energy expansion could carry hidden biodiversity costs, according to a study on China published in the journal Science on Thursday.
Phys.org / Stellar spin may explain why repeated black hole flares grow dimmer
At the center of most galaxies lies a supermassive black hole, with a mass millions to billions of times that of our sun and some of the most extreme gravity in the universe.
Phys.org / Italian scientists bet on octopus to fight crab invasion
From a fishing trawler in the Adriatic, Italian scientists gently release thousands of tiny octopuses in the hope of fighting an invasive crab species that has devastated local fisheries.
Medical Xpress / Officials warn wildland firefighters about the risks of using a supplement for smoke exposure
Fire and medical officials have issued warnings about a supplement offered to Western wildland firefighters who have been exposed to toxic chemicals while battling some of the country's biggest blazes.
Medical Xpress / Compound produced after eating pomegranates targets stiff-heart failure pathway, early tests suggest
A compound produced in the body after eating pomegranates improves heart function by up to 80% in a type of heart failure with limited treatment options.
Phys.org / Twenty years and 7,500 fossils reveal what blurs Earth's marine fossil record
In productive marine environments, a square meter (10.8 square feet) of seafloor can be perforated by hundreds to thousands of isolated and interconnected tunnels through which crawl and writhe a cornucopia of clams, shrimp, ...
Phys.org / First pair of feeding supermassive black holes found in a Green Pea galaxy
Astronomers have discovered the first confirmed dual active galactic nucleus in a Green Pea galaxy, revealing two supermassive black holes growing at the same time inside a compact, intensely star-forming system. X-ray observations ...
Medical Xpress / Lung tumor bacteria plus vitamin B2 metabolite may boost immune response to cancer
Bacteria in lung tumors may boost the activation of innate immune cells in the presence of a common vitamin metabolite, according to a preclinical study by researchers from the Johns Hopkins Kimmel Cancer Center and its Bloomberg~Kimmel ...
