Phys.org / Small doses of caustic soda increase biogas production from banana waste
Low concentrations of caustic soda (sodium hydroxide, NaOH) are more efficient than high doses for preparing organic waste for biogas production. This finding increases methane production, reduces reagent consumption and, ...
Phys.org / Rethinking how we name and classify our human ancestors following recent evolutionary discoveries
Recent advances in our understanding of human evolution challenge the way we currently name and classify our ancestors, according to new research from Monash University. The study, published in the American Journal of Biological ...
Phys.org / Shackled men in 2,600-year-old Greek mass graves were likely locals, archaeologists find
In 2016, archaeologists working at the Phaleron Burial Ground, part of the ancient Attica region, uncovered an astonishing sight: three mass graves dating to the 7th and 6th centuries BCE containing the skeletons of 79 adult ...
Medical Xpress / Experimental pill targets nerve pain pathway, cutting opioid use after abdominal surgery
Opioids can be highly effective at relieving moderate to severe pain, whether it comes from surgery, an injury or conditions such as cancer. They work by activating opioid receptors in the brain and body, which block pain ...
Phys.org / Warming waters draw summer 'feeding frenzies' by whales off Greenland
The effects of global warming depend on species: The losers are legion, but a lucky few are winners. Now, researchers have shown that baleen whales are taking advantage of a newly opened-up fish bonanza in the Greenland Sea, ...
Phys.org / Dark matter may be gravitationally lensing a likely source of cosmic neutrinos
Astronomers have discovered that the jet of a distant blazar has been gravitationally lensed by an unseen source of dark matter. Led by Silke Britzen at the Max Planck Institute for Radio Astronomy in Germany, the team's ...
Phys.org / Strain flips Hall signal in altermagnetic manganese telluride, suggesting a path to practical spintronics
Time-reversal symmetry is an exotic behavior found in systems whose internal physics looks different when running forward versus backward in time. For some time, physicists have searched for this behavior in systems with ...
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 / 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 / Oases in the desert of Arabia created 'brands' in the Bronze Age
Did brands exist before modern society, in noncapitalist economies? An international team led by Marta Luciani of the University of Vienna has made unexpected discoveries about Bronze Age trade: Yes, brands did indeed exist ...
Medical Xpress / Aging reprograms skin genetic activity and promotes inflammation, study reveals
As we age, the skin loses part of its ability to regenerate, heal wounds and maintain an effective barrier against the outside world. Among the causes of this deterioration is low-grade, persistent age-associated inflammation, ...
Phys.org / Search in strange quark sector reveals new particle possibilities
Despite science's best efforts to classify the vast menagerie of subatomic particles discovered over the past few decades, some exotic varieties defy explanation. Now, nuclear physicists at the U.S. Department of Energy's ...
