Science Glance
It may not be space debris, errant asteroids, supply shortages, thruster malfunctions or even the malevolent aliens envisioned in so many Hollywood films that thwart astronauts on any mission to Mars. It may be the ubiquitous galactic cosmic rays.
Researchers said on Friday long-term exposure to these rays that permeate space may cause dementia-like cognitive impairments in astronauts during any future round-trip Mars journey, expected to take at least 2-1/2 years.
Cosmic rays may damage brains of astronauts
'Bizarre' Jurassic dinosaur discovered in remarkable new find
Fossil hunters in Chile have unearthed the remains of a bizarre Jurassic dinosaur that combined a curious mixture of features from different prehistoric animals.
The evolutionary muddle of a beast grew to the size of a small horse and was the most abundant animal to be found 145 million years ago, in what is now the Aysén region of Patagonia.
Chicago offers reparations package to police torture victims
Mayor Rahm Emanuel and several Chicago aldermen are offering what they call a reparations package for the victims of torture under the city's former police commander, Jon Burge.
The city said Tuesday that the package will include an apology, a $5.5 million fund and city services, such as job training and tuition for victims and their families.
Pot research stalled even as legalization gains momentum
Speaking by phone, Anthony Fabrizio was on a roll about his career in cannabis research when he suddenly fell silent. You could hear the San Francisco–based research director stammering, then grunting. Silence again.
Fabrizio returned to the conversation more than 10 seconds later. He chose his next words gingerly, like someone trying to find a light switch in a dark room, placing one hand in front of the other.
Much Rests On The Enhanced Large Hadron Collider
Get ready to look at the universe through a new window.
Later this month, the Large Hadron Collider, or LHC, the behemoth particle accelerator operated by the European Organization for Nuclear Research (CERN), will be back in action after a two-year hiatus.
The pause was intentional, giving technicians and engineers time to ramp up the collision energy by almost a factor of two. In particle collisions, the higher the energy, the bigger the payoff, as the energy of the colliding particles gets translated into the masses of the debris, following the E=mc2 prescription.
Spy agencies fund climate research in hunt for weather weapon, scientist fears
A senior US scientist has expressed concern that the intelligence services are funding climate change research to learn if new technologies could be used as potential weapons.
Alan Robock, a climate scientist at Rutgers University in New Jersey, has called on secretive government agencies to be open about their interest in radical work that explores how to alter the world’s climate.
UK Scientists: Aliens May Have Sent Space Seeds To Create Life On Earth
Scientists in the U.K. have examined a tiny metal circular object, and are suggesting it might be a micro-organism deliberately sent by extraterrestrials to create life on Earth.
Don't be fooled by the size of the object in the microscopic image above. It may appear to look like a planet-sized globe, but in fact, it's no bigger than the width of a human hair.
