How smart cities will protect us from natural disasters in the future

How smart cities will protect us from natural disasters in the future The smart cities movement aims to gird cities with connected sensors that can alert communities about a disaster in time to avert or modify its course.Thankfully, the smart cities movement does not rest entirely in the hands of government entities, and citizens can play an important role in crowd sourcing their own smart communities.

Astronomers spot mysterious objects spewing out gas at a quarter the speed of light

Astronomers spot mysterious objects spewing out gas at a quarter the speed of light In fact, surveying x-ray sources occasionally results in entirely new, unexplained phenomena.These ultra-bright x-ray sources are blasting out gas at more than a quarter the speed of light, far faster than should be possible.

Ancient alien life may be harder to detect than we thought thanks to radiation

Ancient alien life may be harder to detect than we thought thanks to radiation The ongoing search for alien life doesn’t necessarily mean finding extraterrestrial organisms that are alive right now.While that would be great, finding solid evidence of extinct life on Mars or Europa would be almost as amazing.

Ancient supernovae may have accelerated evolution on Earth

Ancient supernovae may have accelerated evolution on Earth Now, new evidence shows that those previously discovered supernovae would have had a profound effect on Earth, and potentially on the development of the life it held.The expectation was that such distant explosions wouldn’t have a significant effect on the surface, but modelling revealed a significant uptick in surface radiation exposure.

Smartchip launches in NZ to safeguard against mobile phone radiation

Smartchip launches in NZ to safeguard against mobile phone radiation An Aussie company is making moves to reduce mobile phone radiation with its latest development.With almost five million mobile phones in use in New Zealand, Lif3 Global saw an opening to launch the product here.

With MIT’s new imaging tech, now you can judge a book right through the cover

With MIT’s new imaging tech, now you can judge a book right through the cover Ten years ago, MIT researchers demonstrated they could use terahertz imaging to read a letter inside a sealed FedEx envelope.It starts out using terahertz radiation, which is a band of EM radiation that has lower energy and longer wavelength than the visible and IR bands.

Unexpected, mysterious x-rays found emanating from Pluto

Unexpected, mysterious x-rays found emanating from Pluto The image above may look like a blue blob, but it’s actually the dwarf planet Pluto.If this is confirmed, Pluto would be the most distant x-ray source in the solar system.

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.
