Phys.org / Ancient Māori remains point to largely plant-based diets before colonization
New research led by the University of Otago—Ōtākou Whakaihu Waka, in close partnership with mana whenua, is shedding new light on Māori diet and burial practices in Aotearoa New Zealand prior to European colonization. The ...
Phys.org / Examining embryo model ethics beyond box-checking
In science, ethical guidelines ensure that research takes place in a way that respects public trust and is conducted responsibly. Traditional ethics approval procedures work well for projects following established practices, ...
Phys.org / Ant larvae control parental care by using odor signals
In the clonal raider ant (Ooceraea biroi), workers in a colony alternate between caring for larvae and laying eggs in a coordinated cycle. Researchers at the Max Planck Institute for Chemical Ecology in Jena have discovered ...
Phys.org / New AI method flags fluid flow tipping points before simulations break down
David J. Silvester, a mathematics professor at the University of Manchester, has developed a novel machine-learning method to detect sudden changes in fluid behavior, improving speed and the cost of identifying these instabilities ...
Phys.org / What if dark matter came in two states?
The absence of a signal could itself be a signal. This is the idea behind a new study published in the Journal of Cosmology and Astroparticle Physics, which aims to redefine how we search for dark matter, showing that it ...
Phys.org / One DNA letter can trigger complete sex reversal
Researchers at Bar-Ilan University have discovered that changing just one letter in DNA can completely alter sex development in mice. In the new study, published in Nature Communications, a single-letter insertion in a non-coding ...
Phys.org / Houston, we have a problem ... with the toilet
After a successful trip around the moon, everything has been going smoothly on the Orion spacecraft's journey back to Earth—except for the $23 million toilet, which has gotten clogged.
Phys.org / Soundscapes from nearby forests are more uplifting than those from faraway places, research suggests
Listening to one-minute-long audio recordings of forests had positive effects on people's short-term well-being, especially when the recordings were from local temperate forests. Study participants residing in Germany perceived ...
Phys.org / Why doesn't the US recycle more plastic? Study points to lack of access
A new University at Buffalo study finds that people in the United States generate similar amounts of plastic packaging waste regardless of income, education level or where they live. Yet wealthier and more college-educated ...
Phys.org / AI trained like a Rubik's Cube solver simplifies particle physics equations
For years, Rutgers physicist David Shih solved Rubik's Cubes with his children, twisting the colorful squares until the scrambled puzzle returned to order. He didn't expect the toy to connect to his research, but recently ...
Phys.org / The lengths male octopuses go to protect the arm they need to mate
For mating male octopuses, one limb is more important than all others. That is the third right arm or hectocotylus, which is used to transfer sperm to the female because the penis cannot do it directly. Losing the limb can ...
Phys.org / Physicists zero in on the mass of the fundamental W boson particle
When fundamental particles are heavier or lighter than expected, physicists' understanding of the universe can tip into the unknown. A particle that is just beyond its predicted mass can unravel scientists' assumptions about ...
