Phys.org / Astronomers reveal hidden lives of the early universe's ultramassive galaxies
An international team of astronomers has uncovered multiple evolutionary paths for the universe's most massive galaxies. Observations of ultramassive galaxies, each containing more than 100 billion stars, show that less than ...
Phys.org / Researchers develop non-destructive spectrometry technique for analyzing fragile archaeological ivory
A research team led by Prof. Wang Zhenyou at the Aerospace Information Research Institute of the Chinese Academy of Sciences (AIRCAS) has developed a microscopic time-gated Raman spectrometer capable of non-destructive, micrometer-scale ...
Phys.org / 'Stomata in-Sight' system allows scientists to watch plants 'breathe' in real-time
For centuries, scientists have known that plants "breathe" through microscopic pores on their leaves called stomata. These tiny valves are the gatekeepers that balance the intake of carbon dioxide into the leaf for photosynthesis ...
Phys.org / Single-atom photocatalyst enables green, oxidant-free C–H cross-coupling reactions
Chemists from the National University of Singapore (NUS) have developed a single-atom photocatalytic strategy that enables oxidant-free cross-dehydrogenative coupling (CDC) reactions between ring-shaped aromatic molecules ...
Phys.org / Other people's backgrounds shape their social position, but I worked hard for mine: The paradox in how we view status
The concept of "hard work v privilege," and what either one says about someone's social status, is an important one.
Medical Xpress / On the hook for uninsured residents, counties now wonder how they'll pay
In 2013, before the Affordable Care Act helped millions get health insurance, California's Placer County provided limited health care to some 3,400 uninsured residents who couldn't afford to see a doctor.
Phys.org / From pint to plate, scientists brew up a new way to grow meat
Yeast left over from brewing beer can be transformed into edible "scaffolds" for cultivated meat—sometimes known as lab-grown meat—which could offer a more sustainable, cost-effective alternative to current methods, according ...
Medical Xpress / Blood test shows when it's safe to stop antibiotics in sepsis patients
A simple blood test can tell doctors when it is safe to stop antibiotics in patients recovering from sepsis, a review led by University of Manchester researchers has found.
Phys.org / Smart polymers harden on demand with light or gentle heat activation
Chemists at Ben-Gurion University of the Negev have developed a "smart" polymer that could make industrial curing, 3D printing and repairs simpler, safer and more energy-efficient with materials whose properties may be tuned ...
Phys.org / 'Hectic' bushfires threaten rural towns in Australian heat wave
Bushfires destroyed houses and razed vast belts of forest in southeast Australia on Friday, firefighters said, as hot winds fanned "hectic" conditions in the tinder-dry countryside.
Medical Xpress / Immune sabotage: How a Vitamin A byproduct compromises the body's normal anti-cancer response
Scientists at the Princeton University Branch of the Ludwig Institute for Cancer Research have identified novel mechanisms by which a metabolic derivative of vitamin A—all-trans retinoic acid—compromises both the body's ...
Medical Xpress / Interpersonal and self-inflicted violence linked to outdoor temperature spikes
Warming temperatures are connected to increases in violence-related hospital visits—including both interpersonal and self-inflicted violence—according to a new analysis of 14 years of Medicaid claims data.
