Life in evolution's fast lane

Most living things have a suite of genes dedicated to repairing their DNA, limiting the rate at which their genomes change through time. But scientists at Vanderbilt and University of Wisconsin-Madison have discovered an ...

Studying DNA breaks to protect future space travelers

Earth's atmosphere shields life on the ground from cosmic radiation that can damage DNA. Astronauts in space have no such protection, and that puts them at risk. An investigation on the International Space Station examines ...

Testing radiation resistance without using a nuclear reactor

The University of Huddersfield's combined electron microscope and ion beam accelerator is a world-class facility responsible for a large and growing global network of research collaborations. One of the latest is a partnership ...

Tiny 'water bears' can teach us about survival

Earth's ultimate survivors can weather extreme heat, cold, radiation and even the vacuum of space. Now the U.S. military hopes these tiny critters called tardigrades can teach us about true toughness.

Proposed rule change worries some about radiation regulation

The EPA is pursuing rule changes that experts say would weaken the way radiation exposure is regulated, turning to scientific outliers who argue that a bit of radiation damage is actually good for you—like a little bit ...

Trump's EPA moving to loosen radiation limits

The Trump administration is quietly moving to weaken U.S. radiation regulations, turning to scientific outliers who argue that a bit of radiation damage is actually good for you—like a little bit of sunlight.

Reconsidering damage production and radiation mixing in materials

Understanding the nature of radiation damage in materials is of paramount importance for controlling the safety of nuclear reactors, semiconductor technology, and designing reliable devices in space. For more than 60 years, ...

Space radiation is risky business for the human body

While people protect their eyes from the sun's radiation during a solar eclipse, NASA's Human Research Program (HRP) is working to protect the whole human body from radiation in space. Space radiation is dangerous and one ...
