Phys.org / Four 'Little Red Dot' pairs hint at black hole mergers in early universe
After analyzing infrared images captured by the James Webb Space Telescope (JWST), an international team of researchers has discovered multiple massive black holes from approximately 12.5–12.8 billion years ago that were ...
Phys.org / New gene activation tool may do what CRISPR cannot: Work inside the body
The ability to precisely adjust the expression of genes inside the human body—ramping up protective ones and tamping down harmful ones—holds enormous potential for treating and preventing disease. But the standard molecular ...
Phys.org / Manganese's emission lines shine a light on galactic evolution
In a new study, a team of astronomers has identified wavelengths of light that could be useful for tracing the chemical evolution of the universe. Using computational modeling to simulate how electrons interact with manganese ...
Phys.org / A 112°C test may separate 1,000-year-old pottery from recent forgeries
Museums around the world now have a new tool to distinguish real ancient clay artifacts from fakes. The research team at UC San Diego's Scripps Institution of Oceanography, led by postdoctoral scholar Yoav Vaknin, found a ...
Phys.org / Peptides can form well-defined structures in harsh, Venus-like conditions
When exploring solar system bodies for signs of past or present life, scientists have mainly focused on planets that have (or had) a liquid surface similar to Earth's. However, mounting evidence suggests that the ingredients ...
Phys.org / Small-plane fuel raises lead levels up to sevenfold near Oregon airports, study suggests
Emissions from aircraft that use leaded aviation gasoline are a significant source of environmental pollution in neighborhoods near regional airports, according to a new study by researchers at Oregon State University and ...
Phys.org / Caught right-handed: Mystery of coiling snake embryos explained
An international team led by Canadian researchers has found evidence explaining why snake embryos form a curious spiral. This ability to coil as embryos enables snakes to hatch with the longest bodies of all vertebrates.
Phys.org / AI chatbot use for emotional support tied to loneliness in students
Young people leaning on AI chatbots for emotional support or personal advice are significantly more likely to struggle with serious emotional problems, feel isolated and doubt that they truly matter to others, a new uOttawa ...
Phys.org / Antarctica is home to microbes found nowhere else on Earth
Scientists have often wondered about species that are unique to Antarctica. But the focus has mainly been on animals, like feathery penguins. CIRES researchers wanted to dig deeper—into the soils—believing tiny organisms ...
Phys.org / Solar orbiter detects ion sorting at the solar wind's magnetic boundary
A Southwest Research Institute (SwRI) study of data from the European Space Agency's (ESA) Solar Orbiter gives the most detailed view of the heliospheric current sheet (HCS) to date. The HCS is a sprawling, undulating surface ...
Phys.org / Tiny mirror that controls light in 3D could make microscopes smaller and faster
Researchers use tightly focused laser beams to image biological samples, shape materials with microscopic precision and generate displays. But using those beams in three dimensions requires more than sweeping light from side ...
Phys.org / Managing chronic conditions together may be key to longer lifespan, canine study finds
As dogs age, many develop more than one chronic health condition. New research from Texas A&M College of Veterinary Medicine and Biomedical Sciences (VMBS) shows those conditions can dramatically shorten a dog's lifespan, ...
