Astronomers discovered eight new echoing black hole binaries in our galaxy, enabling them to piece together a general picture of how a black hole evolves during an outburst. The findings will help scientists trace a black hole’s evolution as it feeds on stellar material.

Scattered across our Milky Way galaxy are tens of millions of black holes — immensely strong gravitational wells of spacetime, from which infalling matter, and even light, can never escape. Black holes are dark by definition, except on the rare occasions when they feed...

During experiments in animal models, researchers at the University of Kansas have discovered a possible new approach to immunization against Alzheimer’s disease (AD).

Their method uses a recombinant methionine (Met)-rich protein derived from corn that was then oxidized in vitro to produce the antigen: methionine sulfoxide (MetO)-rich protein. This antigen, when injected to the body, goads the immune system into producing antibodies against the MetO component of beta-amyloid, a protein that is toxic to brain cells and seen as a hallmark of Alzheimer’s disease. The findings have been just published in the peer-reviewed open-access journal Antioxidants.

“As we age, we have more oxidative stress, and then beta-amyloid and other proteins accumulate and become oxidized and aggregated ...

As Wi-Fi is deployed more widely in cities, and perhaps at higher frequencies, it may depend on an abundant urban asset: streetlight poles.

To help ensure these networks work well, researchers at the National Institute of Standards and Technology (NIST) have developed and verified a novel mo...

Researchers from The Australian National University (ANU) have found an alternative explanation for a mysterious gamma-ray signal coming from the centre of the galaxy, which was long claimed as a signature of dark matter.

Gamma-rays are the form of electromagnetic radiation with the shortest wavelength and highest energy.

Co-author of the study Associate Professor Roland Crocker said this particular gamma-ray signal — known as the Galactic Centre Excess — may actually come from a specific type of rapidly-rotating neutron star, the super-dense stellar remnants of some stars much more massive than our sun.

The Galactic Centre Excess is an unexpected concentration of gamma-rays emerging from the centre of our galaxy that has long puzzled astronomers.

“Our work does not throw ...
