Phys.org / Ultra-faint galaxy discovered near Andromeda may be 12.5 billion years old
A new ultra-faint dwarf galaxy has been discovered in the vicinity of Andromeda (M31), the Milky Way's large neighboring galaxy. The new study, published in Astronomy & Astrophysics suggests that the galaxy, named And XXXVI, ...
Medical Xpress / Urgent call for better access to personalized cancer care
A University of Queensland study has found that patient access to one of the most exciting frontiers in cancer treatment is being stalled because health systems struggle to accurately assess its cost-effectiveness. The study, ...
Phys.org / Deep inside crocodile skulls, 100 million years of brain evolution barely registers
Although modern crocodiles, alligators, caimans and gharials are restricted to the tropics, their fossil record tells a very different story. Ancient crocodylians once inhabited much of the globe and exhibited a remarkable ...
Medical Xpress / A species of gut bacteria could ease anxiety and diarrhea-predominant IBS
Irritable bowel syndrome (IBS) is a condition characterized by abdominal pain, bloating and changes in bowel movements, estimated to affect between 10% and 15% of people worldwide. Past studies suggest that in many cases ...
Phys.org / A single origin story for the Milky Way's most mysterious stars
Lurking at the heart of the Milky Way, Sagittarius A* (Sgr A*) is a supermassive black hole four million times the mass of the sun, surrounded by a puzzling collection of young, massive stars whose orbits have long defied ...
Medical Xpress / Bioresorbable implant electrically stimulates organs, nerves and muscles then vanishes after treatment
To treat or manage various heart, gastrointestinal and neurological conditions, including arrhythmias, heart block, gastroparesis, epilepsy and some nerve injuries, doctors rely on a technique known as electrical stimulation. ...
Phys.org / Ozone depletion began decades before discovery of ozone hole, scientists find
The Antarctic ozone hole was discovered in 1985, when scientists observed a severe depletion in Earth's protective layer of stratospheric ozone. Industrial chemicals known as chlorofluorocarbons (CFCs), then widely used as ...
Science X / Kids shrug off sunk-cost bias until about age 6, behavioral experiments reveal
Ever wonder why adults cling to things in which they've invested time or effort? In behavioral experiments, people often predict that they would stick with an option just because it was harder to get. Psychologists call this ...
Phys.org / New Horizons tracks solar wind slowdown as interstellar atoms add drag
A new Southwest Research Institute (SwRI) study based on data from NASA's New Horizons spacecraft has uncovered insights into why the solar wind gradually slows as it moves toward the edge of the solar system and the boundary ...
Phys.org / Disorder creates direction-dependent optics in compound semiconductors
An international research team has demonstrated that the intrinsic disorder of the compound semiconductor CuInSnS₄ can be exploited to influence its optical properties. While the atomic vibrations also sense the local disorder, ...
Phys.org / Coastal and estuarine carbon removal technique may backfire when pushed too far
Scientists investigating a proposed way to remove carbon dioxide from the atmosphere using seawater have found that adding too much alkalinity to neutralize acids can trigger chemical reactions that undermine the process.
Phys.org / Why Europe's rising plant diversity may signal habitat disruption, not ecological recovery
The number of plant species in many ecosystems in Europe has grown rather than shrunk over the last 100 years. However, this is not necessarily cause for celebration, as this local increase is primarily due to generalists ...
