BPA-free plastic doubts raise new health concerns

BPA-free plastic doubts raise new health concerns

BPA-free plastic may not be the health safeguard it was once believed to be, with new research indicating the risks involved in plastic bottles and food containers could be just as high as the BPA it replaced. The early study has suggested that - in mice at least - chemicals in BPA-free plastics could trigger reproductive problems.

NASA ADEPT foldable “umbrella” shields spacecraft from intense heat

NASA ADEPT foldable “umbrella” shields spacecraft from intense heat

NASA has unveiled a new umbrella-shaped heat shield called Adaptable Deployable Entry Placement Technology, a device capable of folding during transport. Thanks to this design, which NASA describes as "game-changing," the space agency may one day be able to deliver large heat shields that, when fully expanded, are wider than the diameter of the rocket transporting it.

ISS images show massive Hurricane Florence from 400 km up

ISS images show massive Hurricane Florence from 400 km up

ISS astronauts have the best view of Earth available with a giant orbiting space station packed with cameras and portals to look out of. The ISS is currently orbiting at an altitude of about 400 km above the surface of the Earth meaning it has an incredible view of Hurricane Florence as it rages. The images here were all taken by astronaut Alexander Gerst on September 12.

NASA increases Opportunity rover recovery effort as sunlight returns

NASA increases Opportunity rover recovery effort as sunlight returns

NASA is ramping up its Opportunity rover recovery efforts, revealing that its latest data from the Mars Reconnaissance Orbiter shows an increasing amount of sunlight reaching the vehicle. Given the additional sunlight, NASA says its Opportunity team has started sending a greater number of commands to the rover -- instead of sending these commands only three times a week, the scientists are now sending commands multiple times every day.

Three new fish species discovered over 4 miles below ocean’s surface

Three new fish species discovered over 4 miles below ocean’s surface

The realm three new species of fish recently discovered live in is one of the most inhospitable homes imaginable. These three fish are all snailfish and were discovered about 4.6 miles below the surface of the Pacific Ocean. The researchers who discovered these three new species were able to capture a specimen and get the fish on video feeding.

NASA considers letting corporations put brand names on rockets

NASA considers letting corporations put brand names on rockets

During the second public meeting of the NASA Advisory Council (NAC), NASA administrator Jim Bridenstine presented the topic of rocket naming rights and similar options for corporations. Under such an idea, assuming it is ever implemented, private companies may have the opportunity to slap their logo on a rocket, associate their brands with space missions, and even offer products with astronaut endorsements.

Scientists create highest resolution Antarctic map ever

Scientists create highest resolution Antarctic map ever

Antarctica is a very cold and desolate place and maps of the continent were not of very high resolution in the past. Previous maps had a resolution of 1,000 meters, but a new map has been created that changes that. The new high-resolution map created by a mapping project called The Reference Elevation Model of Antarctica has a resolution of 2 to 8 meters.

Pluto is a planet argues new research – and it always was

Pluto is a planet argues new research – and it always was

The debate over whether Pluto is a planet has been ongoing for years and there's no signs of that ending. New research out of the University of Central Florida argues against the 2006 definition that stripped Pluto of its status, citing research into 200 years of scientific literature on the requirements for classifying a planet.

Scientists find cells in hippocampus linked to bravery and anxiety

Scientists find cells in hippocampus linked to bravery and anxiety

Scientists have identified cells in the hippocampus that may be responsible for the degree of bravery exhibited by an individual, according to a new study. The findings may pave the way for future anxiety treatments that target only the part of the brain responsible for the anxious disposition rather than the entire brain. The research comes out of Brazil's Federal University of Rio Grande do Norte and Sweden's Department of Neuroscience of Uppsala University.

Antarctica Map: Highest resolution terrain map yet made

Antarctica Map: Highest resolution terrain map yet made

Today we're having a peek at the newly revealed and newly-public "most accurate" high resolution terrain map of Antarctica. This is REMA, or the Reference Elevation Model of Antarctica. Straight from the folks at Ohio State University, this map is made by what its creators say is "applying fully automated, stereo auto-correlation techniques to overlapping pairs of high-resolution optical satellite images."

MIT researchers develop robot arm able to pick up any object after inspection

MIT researchers develop robot arm able to pick up any object after inspection

One of the biggest challenges for robots is something that humans can do so easily we don’t even see it as a challenge. When we walk through our home if we see something like a mug on the table we can pick it up by the handle no matter the orientation. Robotic hands find something that simple to be a major challenge. Human dexterity is credited in part to our eyes because we can see the object clearly making it easy to pick up.

10,500-year-old extinct Great Irish Elk skull and antlers found in lake

10,500-year-old extinct Great Irish Elk skull and antlers found in lake

A fisherman in Ardboe, a small village in Ireland, discovered the skull and antler remains of an extinct Great Irish Elk, a creature that hasn't roamed the Irish landscape in thousands of years. Though this isn't the oldest Great Irish Elk discovery -- that distinction goes to one dated around 14,000-years-old -- it is far more notable: the massive skull and antlers are completely intact.
