Gamma rays 10 times more energetic than thought possible detected

Astronomers have detected the highest-energy light ever seen, streaming in from near the center of the Milky Way. Hundreds of gamma ray signals were detected with ultra-high energies, with the most powerful signals crossing the Peta-electronvolt (PeV) … Continue reading Gamma rays 10 times more energetic than thought possible detected

Hibernating zebrafish offer lessons for healthy human spaceflight

Getting humans safely to a place like Mars is going to pose all kinds of scientific challenges, and a particularly pressing one centers on the rather important issue of human health. Astronauts enduring long-periods in space may be in danger of changes… Continue reading Hibernating zebrafish offer lessons for healthy human spaceflight

Small pilot study claims low-dose radiation may treat severe Alzheimer’s

The idea low-dose radiation can be a treatment for Alzheimer's disease is still controversial with little clinical evidence backing it up

A compelling pilot study has found several treatments of low-dose radiation, delivered from a CT scanner, could increase alertness and responsiveness in people suffering severe late-stage Alzheimer’s disease. The research is still preliminary but there are several larger clinical trials currently underway investigating radiation as a treatment for Alzheimer’s.

Powerful protostars may not be responsible for ending their own growth

Fresh research has cast doubt on the theory that energetic outbursts from young stars blows away the cocoon of gas from which they formed, which in turn prevents them from growing any further. The Milky Way plays host to over 200 billion stars, the ear… Continue reading Powerful protostars may not be responsible for ending their own growth

Radiation bombardment from Jupiter makes Europa glow in the dark

Giving a new meaning to the word “moonshine,” NASA scientists at the Jet Propulsion Laboratory (JPL) in Pasadena, California, have concluded that Jupiter’s moon Europa glows in the dark due to being constantly bombarded with high-energy radiation.Conti… Continue reading Radiation bombardment from Jupiter makes Europa glow in the dark

Researchers discover how gut bacteria can protect from radiation damage

We know radiation therapy is an aggressively toxic treatment methodology for fighting cancer. Gastrointestinal distress is a common side-effect but researchers are only now discovering exactly how the massive population of bacteria living in our gut is… Continue reading Researchers discover how gut bacteria can protect from radiation damage

First Moon radiation measurements reveal risk to astronaut health

Radiation is one of the main dangers of space travel, and with renewed focus on sending human crews back to the Moon it’s important to understand the risks they face. Now we have the clearest data on that to date, thanks to a dedicated instrument onboa… Continue reading First Moon radiation measurements reveal risk to astronaut health

Cosmic rays can destabilize quantum computers, MIT study warns

Quantum computers are advancing at an exciting pace, but unfortunately this progress may soon stall. Cosmic rays streaming down to Earth could interfere with the integrity of the information in these quantum computers, and now an MIT team has shown jus… Continue reading Cosmic rays can destabilize quantum computers, MIT study warns
