Sun Emitted Solar Flare on Oct. 1: NASA

The sun emitted a mid-level solar flare, which reached its peak at 8:13 p.m. EDT on Oct. 1, 2015, said NASA. NASA’s Solar Dynamics Observatory, which watches the sun constantly, captured an image of the event and the solar flares were seen as powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth’s atmosphere to physically affect ...

With Fukushima nuclear accident still fresh in our minds, a new injection will reduce the radiation effects of such nuclear accidents even if they are given one day after the mishap. While it cannot reverse the effects, it can only reduce the adverse impact, said researchers. Exposure to radiation triggers a number of potentially high lethal effects. In which, the ...

Space Weather’s Impact on Earth: Plasma Waves Responsible For Particle Fallout in Atmosphere

Researchers have shown plasma waves buffeting the planet’s radiation belts are responsible for scattering charged particles into the atmosphere for the first time that in a recent study on space weather’s impact on Earth. The study is the detailed analysis of the link between these waves and the fallout of electrons from the planet’s radiation belts so far. The belts ...

Space Travel to Help Humans to Fight Illness on Earth

According to a new study, space travel may help scientists strengthen our bodies’ ability to fight threats to our health. When an astronaut goes to space, his immune system does not work as well in microgravity as on Earth. “Knowing about the astronauts’ health may lead to new treatments on Earth for those with impaired immune systems,” the researchers noted ...

Women Astronauts More Susceptible to Health Hazardous then Men, says NASA Study

In a gender-specific finding, a NASA study has revealed that women are more susceptible to physiological, psychological and behavioural changes that occur during spaceflight. The report stated that women have greater loss of blood plasma volume than men during spaceflight and women’s stress response characteristically includes a heart rate increase while men respond with an increase in vascular resistance (resistance ...

Fukushima nuclear accident: Effects now visible in butterflies, humans next?

The accident at Fukushima Dai-ichi Nuclear Power Plant in japan following the March 12, 2011 earthquake and tsunami caused a massive release of radioactive materials to the environment that butterflies have shown symptoms of mutation and malformation, sending signals that the local human population may have to face the impact. A research team has shown that the accident caused physiological ...
