Scientists at the Rutherford Appleton Laboratory in the UK are working on a Star Trek-like deflector shield to enable the transport of humans between planets and stars without subjecting them to lethal doses of cosmic radiation. This research comes at a vital time, as numerous groups, including NASA, look to send humans to Mars -- but without adequate shielding from the Sun's harsh cosmic rays, it could be a one-way trip full of vomiting, diarrhea, and more serious symptoms of radiation poisoning, such as death.
