Rare near-Earth binary asteroid features two massive space rocks

Rare near-Earth binary asteroid features two massive space rocks

In December 2017, the Cadi Ayyad University Morocco Oukaimeden Sky Survey discovered a space object dubbed 2017 YES. Not much was known about the object at that time, but thanks to some of the world's biggest radio telescopes, we now have an answer: it is a binary asteroid. According to NASA, which has published a GIF of the actual asteroids, this is one of only four near-Earth binary asteroids with similar masses ever spotted.

Massive diamond cache may be hidden 100 miles below Earth’s surface

Massive diamond cache may be hidden 100 miles below Earth’s surface

Diamonds are expensive, but not terribly rare. A new report indicates that Earth may have a truly massive cache of them located about 100 miles beneath the Earth's surface, a depth that is too deep for present drilling technologies. The discovery was made using seismic activity data, which revealed an anomaly with sound waves passing faster than expected through part of the Earth's interior.

Scientists figure out how to split water into hydrogen and oxygen in space

Scientists figure out how to split water into hydrogen and oxygen in space

Some of the biggest challenges with sending humans to distant planets like Mars comes in being able to get enough fuel, water, and oxygen onto the spacecraft and habitats needed to support humans. Scientists have now shown that it is possible to split water into hydrogen and oxygen in space. The hydrogen can be used for fuel for spacecraft while the oxygen is for supporting life.

NASA details ‘spiders’ on Mars with crazy new photo

NASA details ‘spiders’ on Mars with crazy new photo

NASA has released an image showing "spiders" on Mars, small darks spots on the reddish landscape with tendrils one could easily perceive as tiny legs. The marks were captured by the NASA Mars Reconnaissance Orbiter in mid-May at Mars' south pole during the planet's winter season. The "spiders" make their appearance as the season turns to spring, dotting the terrain.

Antioxidant health benefits of sleep teased in new study

Antioxidant health benefits of sleep teased in new study

A new study hints at the potential antioxidant benefits of sleep, as well as the damage that getting too little sleep may cause. Researchers studied the lowly fruit fly to help understand the role sleep may play in health, finding that fruit flies with a mutation that resulted in short sleeping times were sensitive to oxidative stress.

MeerKAT radio telescope captures clearest image of galaxy’s center

MeerKAT radio telescope captures clearest image of galaxy’s center

A 64-dish radio telescope called MeerKAT has been fired up in Carnarvon, South Africa. In the future, MeerKAT will be part of a larger instrument called Square Kilometer Array (SKA), a massive multi-radio telescope project expected to span about one square kilometer, which is what the SKA name refers to. The project won't be fully operational until the end of the next decade, but will be the most powerful of its kind when that day comes.

Scientists discover source of high-energy cosmic neutrinos for the first time

Scientists discover source of high-energy cosmic neutrinos for the first time

A group of scientists has for the first time located a source of high-energy neutrinos. Neutrinos are elementary particles that can travel billions of light years across the universe and can pass through stars, planets, and galaxies without being affected. The search for the location of a single neutrino began when it was recorded by the IceCube neutrino telescope at the South Pole.

Obesity sans other risk factors doesn’t increase mortality rate: study

Obesity sans other risk factors doesn’t increase mortality rate: study

A newly published study reveals that obesity in the absence of other metabolic risk factors does not, by itself, increase the individual's risk of death. The research comes out of York University's Faculty of Health, which found that obesity in the absence of diabetes, high blood pressure, and similar isn't associated with increased mortality. The findings are based on a study covering more than 54,000 adults who had either obesity by itself or obesity with other metabolic risk factors.

Behold, 3D color X-rays: MARS scanner, made with CERN tech

Behold, 3D color X-rays: MARS scanner, made with CERN tech

This week the folks at MARS Bioimaging revealed the first 3D color X-Ray of the insides of a human body. They've got a device called the MARS large bore spectral scanner, AKA the MARS spectral x-ray scanner - and we're crossing our fingers for a simpler name as the product is further developed, too. This scanner uses an adaptation of technology first used by CERN in the hunt for the God particle.

Boeing, SpaceX delays have NASA scrambling for crew contingency plan

The US Government Accountability Office (GAO) has released a new report detailing the NASA Commercial Crew Program and delays its two contracted companies, Boeing and SpaceX, are experiencing. Both space companies are behind schedule, with the report revealing that NASA anticipates Boeing being slightly closer to completion than SpaceX.

Scientists say rare black hole-neutron stars could identify rate of universe’s expansion

Scientists say rare black hole-neutron stars could identify rate of universe’s expansion

Scientists say that the universe has been expanding ever since it came into existence about 13.8 billion years ago. As the universe expands the planets, galaxies, and stars have been carried along with it. Scientists have long tried to measure the rate of expansion in the universe.

Study finds high blood pressure associated with Alzheimer’s disease

Study finds high blood pressure associated with Alzheimer’s disease

A newly published study has linked high blood pressure to brain diseases, including Alzheimer's. Researchers specifically point to blood pressure later in life, finding that patients with higher systolic blood pressure had a greater risk of brain lesions. The study followed 1288 older individuals until their death, at which point their brains were studied.
