Earth's Water Most Likely Accreted at the Same Time as the Rock

New research from Woods Hole Oceanographic Institution shows that Earth’s water most likely accreted at the same time as the rock, suggesting that Earth received most of its water relatively early from chondrite-like bodies. Earth is known as the Blue Planet because of its oceans, which cover more than 70 percent of the planet’s surface […]

Low Oxygen Levels Delayed the Appearance of Animals on Earth

A new study reveals that oxygen levels during the “boring billion” period were only 0.1% of what they are today, providing the first evidence that oxygen levels were low enough during this period to potentially prevent the rise of animals. Geologists are letting the air out of a nagging mystery about the development of animal […]

NASA Completes Initial Assessment after Rocket Explosion

NASA’s Wallops Flight Facility has completed an initial assessment of Wallops Island, but noted that it will take many more weeks to further understand and analyze the full extent of the effects of the event. The Wallops Incident Response Team completed today an initial assessment of Wallops Island, Virginia, following the catastrophic failure of Orbital […]

Decoy Drug Allows Brain to Form New Connections

New research from Stanford Bio-X scientists shows that the brains of adult mice are able to form new synapses by disabling the function of a single protein for as little as a week. This research has the potential to help adults recover from stroke and forms of blindness or to prevent the loss of connections […]

New Technology Allows Microscopic Devices to Autonomously Find Their Way

Researchers from MIT have developed a new target-finding mechanism that allows microscopic devices to autonomously find their way to areas of a cell surface. Nature has developed a wide variety of methods for guiding particular cells, enzymes, and molecules to specific structures inside the body: White blood cells can find their way to the site […]

Researchers Create Possible Precursor to Life

Newly published research details how a team of scientists used a virtual computer experiment to discover information strings with peculiar properties. How did life originate? And can scientists create life? These questions not only occupy the minds of scientists interested in the origin of life, but also researchers working with technology of the future. If […]

Assessing the Technical Feasibility of the Proposed Mars One Mission

A new independent assessment of the Mars One Mission from MIT engineers reveals that the project may have to take a step back, at least to reconsider the mission’s technical feasibility. In 2012, the “Mars One” project, led by a Dutch nonprofit, announced plans to establish the first human colony on the Red Planet by […]

New Research Shows Solid Nanoparticles Can Deform Like a Liquid

Using a combination of laboratory analysis and computer modeling, new research shows that nanoparticles keep their internal crystal structure while deforming like a liquid. A surprising phenomenon has been found in metal nanoparticles: They appear, from the outside, to be liquid droplets, wobbling and readily changing shape, while their interiors retain a perfectly stable crystal […]

Killer Whales Demonstrate Cross-Species Vocal Learning

A newly published study reveals that killer whales (Orcinus orca) can engage in cross-species vocal learning, revealing that they shifted the types of sounds they made to more closely match the bottlenose dolphins they cross-socialized with. Washington, D.C. — From barks to gobbles, the sounds that most animals use to communicate are innate, not learned. […]

Antarctic Sea Ice Reaches New Maximum

Long-term satellite records show that the five-day average of Antarctic sea ice extent reached a new record high this year. This year, Antarctic sea ice reached a record maximum extent while the Arctic reached a minimum extent in the ten lowest since satellite records began. Why are these trends going in opposite directions? Image Credit: […]

Lizard Study Shows Trade is a Force in Biodiversity

A newly published study shows that trade is one of the major drivers of biodiversity among lizard species in the Caribbean islands, finding that the amount of trade an island receives can explain to a large extent the number of invasive species on an island. It may be a cliché to say it, but the […]
