The presence of unusually energetic gamma rays seen in some afterglows from intense gamma-ray bursts (GRBs) could be explained by a new mathematical model developed by RIKEN researchers. This finding could help to shed light on the origin of GRBs.

A GRB is a spectacular eruption of energy produced by violent events such as the explosive death of a massive star, or the collision of two neutron stars...

5G+ (5G/Beyond 5G) is the fastest-growing segment and the only significant opportunity for investment growth in the wireless network infrastructure market, according to the latest forecast by Gartner, Inc. But currently 5G+ technologies rely on large antenna arrays that are typically bulky and come only in very limited sizes, making them difficult to transport and expensive to customize.

Researchers from Georgia Tech’s College of Engineering have developed a novel and flexible solution to address the problem...

Burst of Accumulated Zinc shows how the Mineral Boosts Immune Function, suggesting ways to Improve Health

In mice, zinc helps thymus of the immune system regrow and immune-cell recovery after bone marrow transplant. Zinc’s immune-boosting properties are well-established, but scientists haven’t known exactly how it works. In a new study published online March 25 in the journal Blood, Fred Hutchinson Cancer Research Center scientists reveal two ways the mineral supports immunity and suggest how it could be used to improve health.

Using mice, the team discovered that zinc is needed for the development of disease-fighting immune T cells and prompts regeneration of the thymus, the immune organ that produces T cells.

“This study adds ...

Impact of Black Hole Winds, Radiation examined in new study

Black holes are regions of space where gravity is so strong that nothing can escape. New research is examining the radiation and winds emanating from black hole activity and shows how they may exert effects on nearby planets.

“The impact of AGN outflows on the surface habitability of terrestrial planets in the Milky Way” is a research paper by the team of astrobiologist Manasvi Lingam and astrophysicist Eric Perlman from Florida Tech’s Department of Aerospace, Physics and Space Sciences, as well as researchers from the University of Rome, University of Maryland and Goddard Space Flight Center...
