Major discovery helps explain coral bleaching

Nils Rädecker spent more than a year studying a coral reef just off the coast of Thuwal, Saudi Arabia. He then replicated these environmental conditions in the aquaria at the Red Sea Research Center.

Mystery particle may explain extreme X-rays shooting from the ‘Magnificent 7’ stars

More than 400 light-years from Earth, there is a cluster of young neutron stars that are too hot for their age. These stars, known as the “Magnificent Seven,” emit a stream of ultra-high-energy X-rays that scientists haven’t been able to explain.  Now, scientists have proposed a possible culprit: axions, theoretical particles that turn into light […]

Changing diets — not less physical activity — may best explain childhood obesity crisis

Physicists propose a new theory to explain one dimensional quantum liquids formation

One dimensional quantum lattice liquids. Credit: I. Morera et al. Phys. Rev. Lett Liquids are ubiquitous in Nature: from the water that we consume daily to superfluid helium which is a quantum liquid appearing at temperatures as low as only a few degrees above the absolute zero. A common feature of these vastly different liquids […]

‘Bumblebee gravity’ could explain why the universe is expanding so quickly

Physicists have long assumed that the universe is pretty much the same in any direction, and now they’ve found a new way to test that hypothesis: by examining the shadow of a black hole. If that shadow is a wee bit smaller than existing physics theories predict, it could help prove a far-out notion called […]

Traditional stereotypes about masculinity may help explain support for Trump

Credit: Pixabay/CC0 Public Domain American politicians have long been expected to uphold a certain veneer: powerful, influential and never vulnerable. New Penn State research has found that these idealized forms of masculinity may also help explain support for Donald Trump in the 2016 presidential election and in the days leading up to the 2020 election. […]

A giant black hole keeps evading detection and scientists can’t explain it

An enormous black hole keeps slipping through astronomers’ nets. Supermassive black holes are thought to lurk at the hearts of most, if not all, galaxies. Our own Milky Way has one as massive as 4 million suns, for example, and M87’s — the only black hole ever imaged directly — tips the scales at a […]

New research may explain severe virus attacks on the lungs — ScienceDaily

In some cases, immune cells in the lungs can contribute to worsening a virus attack. In a new study, researchers at Karolinska Institutet in Sweden describe how different kinds of immune cells, called macrophages, develop in the lungs and which of them may be behind severe lung diseases. The study, which was published in Immunity, […]
