Harsh cosmic rays might give astronauts brain damage on a trip to Mars

Harsh cosmic rays might give astronauts brain damage on a trip to Mars A new NASA-funded study points out that radiation exposure during a long trip to Mars could give astronauts “space brain,” which is a fancy way of saying radiation-induced brain damage.The study focused on determining the effects of exposure to cosmic rays in the amounts you’d encounter on a trip to Mars.

Deep-dwelling bacteria could rewrite our understanding of where alien life could take hold

Deep-dwelling bacteria could rewrite our understanding of where alien life could take hold Finding bacteria in extreme environments, like at thermal ocean vents or in the sulfur pools at Yellowstone, isn’t all that novel.In 1991, remote-control robots brought out samples of pitch-black fungi that had been growing inside the ruins of the Chernobyl reactor.

DARPA tests network of 1,000 handheld radiation detectors in Washington

DARPA tests network of 1,000 handheld radiation detectors in Washington As the first large-scale test of the SIGMA program, DARPA put together a mock kidnapping adventure game.Participants in the exercise were each given a backpack with a small SIGMA radiation detector.

30 years later, $1.6B mega-project finally puts Chernobyl to rest

30 years later, $1.6B mega-project finally puts Chernobyl to rest The Chernobyl reactor (hereafter, Chernobyl) has of course been buried in concrete and steel this entire time, but it’s also been 30 years since Russian authorities put that original “sarcophagus” into place.And the project, called New Safe Confinement, certainly was mega.

Detectors have picked up an unexplained wave of radioactivity across Europe

Detectors have picked up an unexplained wave of radioactivity across Europe “Since only Iodine-131 was measured, and no other radioactive substances, we think it originates from a pharmaceutical company producing radioactive drugs.It is possible to partially reconstruct the path the cloud of radioactivity followed as it spread.

An energy-efficient translucent material may revolutionize the AC industry

An energy-efficient translucent material may revolutionize the AC industry A translucent type of film, the material would reportedly feature the ability to cool a home at the expense of literally zero energy.The abstract of the study posits that “passive radiative cooling draws heat from surfaces and radiates it into space as infrared radiation to which the atmosphere is transparent.

We can't see inside Fukushima Daiichi because all our robots keep dying

We can't see inside Fukushima Daiichi because all our robots keep dying Last month, we reported on new findings about Reactor #2 that showed it was far more radioactive inside than previously measured.Initial attempts to see into Reactor #2 via robotic probe have all failed.

Radioactive boars have taken over towns abandoned after Fukushima

Radioactive boars have taken over towns abandoned after Fukushima Now, former residents of four towns inside that zone are being invited back, but officials have found these towns have new inhabitants.But these boars have been found to have levels of the radioactive element cesium-137 that are 300 times the safe limit for consumption.

Court rules to shut down a mobile tower after a man alleges he got cancer from it

Court rules to shut down a mobile tower after a man alleges he got cancer from it In a unique ruling, India’s Supreme Court has ordered to shut down a mobile tower after a man alleged that he got cancer from its radiation.He was exposed to this "radiation" for 14 years, something he firmly believes  afflicted him with Hodgkin's Lymphoma.

Scientists uncover another possible threat to orbiting spacecraft

Scientists uncover another possible threat to orbiting spacecraft Last month, experts met at a conference in Germany to discuss the pressing issue of space debris orbiting our planet, warning of an exponentially worsening threat.This week, a team of researchers from Stanford, MIT, and the University of Boston have raised another concern about smaller particles that could also threaten orbiting spacecraft.

This Tiny Radioactive Implant is a Powerhouse for Treating Prostate Cancer

This Tiny Radioactive Implant is a Powerhouse for Treating Prostate Cancer ” Even though there does exist a less-extreme path that prostate cancer can take, there’s still a continuum of severity and aggression, just like there is for any kind of cancer.For those people who do require more aggressive treatments such as radiation, there’s a tiny implant among the relatively less-scary options for prostate cancer treatment.

Single-Dose Radiation Found Effective for Prostate Cancer

Single-Dose Radiation Found Effective for Prostate Cancer Iridium also has isotopes that are useful in cancer treatment — and especially in prostate cancer treatment.The results of a two-year study from Europe have come in, concerning the use of iridium-192 in single-dose radiation therapy for prostate cancer.

NASA wants your brilliant ideas for protecting astronauts from radiation

NASA wants your brilliant ideas for protecting astronauts from radiation Now comes word they're accepting ideas on designing a radiation shield for potential deep-space flights.In this case, NASA is hoping to get some good ideas to help protect humans from harmful radiation they'll be exposed to as they traverse space.

Beaming Heat into Space Could Make Your Air Conditioner More Efficient

Beaming Heat into Space Could Make Your Air Conditioner More Efficient A company called SkyCool Systems is leveraging an interesting quirk of physics to improve cooling efficiency by beaming heat into space.The challenge for SkyCool Systems is to harness this process in the light of day.
