Phys.org / Three new extinct walnut species discovered in high Arctic mummified forest
In a new study, scientists describe three new, but long-extinct, walnut species on an island above the Arctic Circle. The fossils were discovered further north than any known walnut species, living or extinct, and represent ...
Phys.org / New mathematical model sheds light on the absence of breastfeeding in male mammals
Being nursed by a single parent could be an evolutionary strategy to curb the spread of harmful microbes in mammals, according to a novel theory developed by mathematicians.
Phys.org / Occupational hazards for ancient Egyptian scribes
Repetitive tasks carried out by ancient Egyptian scribes—high-status men with the ability to write who performed administrative tasks—and the positions they sat in while working may have led to degenerative skeletal changes, ...
Phys.org / Bonnet mushrooms have 'expanded' genomes to make them more adaptable to multiple lifestyles, study finds
A study of multiple Mycena mushroom species, also known as "bonnets," reported in the journal Cell Genomics on June 27 has found that they have unexpectedly large genomes.
Phys.org / Exciting applications for marine degradable, bio- and CO2-based PISOX polymers
Researchers at the Industrial Sustainable Chemistry (ISC) group at the Van 't Hoff Institute for Molecular Sciences have developed a new class of bio- and CO2 based PISOX polymers with surprising properties and applications.
Phys.org / Researchers determine that crystal cells in fruit flies help transport oxygen throughout the body
A team of life scientists at Hanyang University, in Korea, working with a pair of colleagues from the Korea Advanced Institute of Science and Technology, has found that fruit flies use crystal cells to transport oxygen throughout ...
Phys.org / Re-analyzing LHC Run 2 data with cutting-edge analysis techniques allowed physicists to address old discrepancy
Supersymmetry (SUSY) is an exciting and beautiful theory that answers some of the open questions in particle physics. It predicts that all known particles have a "superpartner" with somewhat different properties. For example, ...
Phys.org / NASA picks SpaceX to carry ISS to its watery graveyard after 2030
NASA on Tuesday said it had picked SpaceX to build a vessel to carry the International Space Station back through Earth's atmosphere and on to a final resting place in the Pacific Ocean after it is retired in 2030.
Phys.org / New twists on tornadoes: Earth scientist studies why U.S. has so many tornadoes
Across the Midwest during the warmer months, studying the sky for signs of storms and tornadoes becomes one of the most popular pastimes.
Phys.org / Ecologists reconstruct history of biodiversity in Indo-Australian archipelago and its rise as a hotspot
The Coral Triangle, also known as the Indo-Australian Archipelago, is renowned for having the greatest marine biodiversity on our planet. Despite its importance, the detailed evolutionary history of this biodiversity hotspot ...
Phys.org / Researchers develop deep-learning model that outperforms Google AI system to predict peptide structures
Researchers at the University of Toronto have developed a deep-learning model, called PepFlow, that can predict all possible shapes of peptides—chains of amino acids that are shorter than proteins, but perform similar biological ...
Phys.org / The density difference of sub-Neptunes finally deciphered
An international team led by UNIGE, UNIBE and PlanetS has shown the existence of two distinct populations of sub-Neptunes, resolving a debate in the scientific community.
