Phys.org / New technique pinpoints human DNA inherited from 'ghost' ancestors
UC Berkeley researchers have identified regions of DNA that humans inherited from two unknown ancestors as a result of long-ago interbreeding among modern humans and at least four other archaic human relatives.
Phys.org / Webb reveals warped structure in nearby TW Hydrae's protoplanetary disk
Using the James Webb Space Telescope (JWST), astronomers obtained high-contrast coronagraphic images of the protoplanetary disk around the young, nearby star TW Hydrae. Results of the observational campaign, published July ...
Tech Xplore / Solving the solvent problem to make sodium-metal batteries a more practical energy storage option
Lithium-ion batteries are the leading choice in today's electric vehicle and battery energy storage system industries, but they contain a number of critical minerals—including lithium, cobalt, nickel and graphite—that are ...
Phys.org / Unexpected E. coli response may complicate peptide-based antibiotic combinations
A group of Cornell College students and their professor found surprising results in research on antimicrobial peptides, which are being studied as a method of combating antibiotic resistance. These peptides, part of the innate ...
Phys.org / New museum find shows nature can't stop inventing seahorses
At first glance, it looks exactly like a seahorse. It has the same horse-shaped head tilted down from the body, the same curled, grasping tail and, in the males, a fully enclosed pouch for brooding the young.
Phys.org / Histone acetylation sites reshape DNA condensates, revealing a potential gene-control mechanism
A research team from AIST, the Institute of Science Tokyo, and Ritsumeikan University has demonstrated that the phase behavior of histone–DNA condensates depends on the site of histone acetylation.
Phys.org / Unusual metal oxide shows signs of magnetism under lattice strain in ultrathin layers
Ruthenium dioxide (RuO2) is a metal oxide that commonly serves as an important metallic conductor, quantum material and industrial electrocatalyst. While there have been debates surrounding the magnetic properties of RuO2, ...
Phys.org / Magnetic dopants help quantum dots use light for chemical reactions
Scientists at Los Alamos National Laboratory have demonstrated a new quantum-dot mechanism that could significantly expand the reach of light-driven chemistry. By introducing magnetic manganese dopants into semiconductor ...
Medical Xpress / Cancer cells hijack a fatty acid to escape immune attack in liver metastases
Liver metastases are among the most common and deadly forms of cancer spread. Now, researchers at VIB and KU Leuven, with international collaborators, have discovered how cancer cells exploit a fatty acid abundant in the ...
Phys.org / Laser scanning may help prevent urban trees from falling
For the first time, a group of biologists and engineers from the University of São Paulo (USP) in Brazil applied LiDAR (light detection and ranging) technology to investigate the health of trees and optimize pruning with ...
Medical Xpress / Dementia after age 90: Study clarifies who may be at higher risk
It may seem natural to assume that people experience cognitive decline after age 90, but until recently, researchers had limited evidence about how advanced age affects the brain. This major knowledge gap will need to be ...
Phys.org / DESI side project reveals the spectra of disintegrated exoplanets
Using spectral data from the Dark Energy Spectroscopic Instrument (DESI), astronomers have gained some of the clearest evidence yet that white dwarf stars are accreting debris from disintegrating exoplanets. Captured while ...
