Fragmenting ions and radiation sensitizers

A new study using mass spectrometry is helping piece together what happens when DNA that has been sensitized by the oncology drug 5-fluorouracil is subjected to the ionising radiation used in radiotherapy.

Learning how to protect astronauts from space radiation

There is little known about the effects of space radiation on the human body. Astronauts cannot see or feel it, yet the high doses they are exposed to outside Earth's cocoon pose health hazards for trips to the Moon and Mars. ...

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 ...
