Phys.org / Astronomers catch supermassive black hole in the act of 'waking up'
Astronomers using the Very Long Baseline Array (VLBA) and the Very Large Array (VLA) have caught a supermassive black hole in the act of awakening from a long slumber, providing an unprecedented glimpse into the earliest ...
Phys.org / As the world churns: How bioturbation has shaped ocean floors over 540 million years
The murky world at the bottom of the oceans is now a little clearer, thanks to a new study that tracks the evolution of marine sediment layers across hundreds of millions of years.
Phys.org / Viking silver hoard reveals far-reaching trade links between England and the Islamic world
New research into a remarkable Viking-Age silver hoard discovered in North Yorkshire, led by Dr. Jane Kershaw, Associate Professor of Viking Age Archaeology, School of Archaeology, has shed light on the international scope ...
Phys.org / AI automatically designs optimal drug candidates for cancer-targeting mutations
Traditional drug development methods involve identifying a target protein (e.g., a cancer cell receptor) that causes disease, and then searching through countless molecular candidates (potential drugs) that could bind to ...
Phys.org / Lab-made sugar-coated particle reduces COVID-19 infection rates by 98.6% in human cell tests
Research led by a Swansea University academic has revealed a synthetic glycosystem—a sugar-coated polymer nanoparticle—that can block COVID-19 from infecting human cells, reducing infection rates by nearly 99%.
Phys.org / Hope probe reveals first complete picture of nighttime clouds on Mars
Despite being thinner and drier than Earth's atmosphere, Mars's atmosphere contains clouds composed of tiny water ice crystals. And just as on Earth, these clouds influence the planet's climate. However, most of what we know ...
Phys.org / Dancing dwarf galaxies predict the Milky Way's future
A cosmic dance could be the future of the Milky Way as it tracks a course to collide with neighboring galaxies, a University of Queensland survey has found. The paper is published in the Monthly Notices of the Royal Astronomical ...
Phys.org / Two solutions unlock safer RNA therapies for inflammatory diseases
Lipid nanoparticles (LNPs) are tiny fat bubbles that are used to deliver medicines, genes, and RNA into cells. However, in some cases LNPs can cause harmful inflammation as a result of the process of RNA delivery.
Phys.org / Unpacking chaos to protect coffee: Study untangles the ecological dynamics of ants in Puerto Rico
To help manage agricultural practices with fewer or no pesticides, University of Michigan researchers say they need to understand how ecological systems work on agricultural lands.
Phys.org / Common food bacteria could help make vitamins cheaper and greener
A new study reveals how Lactococcus lactis (L. lactis), a common food bacterium, regulates the production of a key precursor in vitamin K₂ (menaquinone) biosynthesis. The bacteria produce enough of this precursor to support ...
Phys.org / Ocean anomalies traveling north crucial for the Atlantic Meridional Overturning Circulation
Anomalies in temperature and salinity that originate in the midlatitude North Atlantic can affect the Atlantic Meridional Overturning Circulation (AMOC) in the Nordic Seas up to a decade later. A new study published in Communications ...
Phys.org / Students' image tool offers sharper signs, earlier detection in the lab or from space
A group of UBC Okanagan students has helped create technology that could improve how doctors and scientists detect everything from tumors to wildfires.
