Deep Sea Shrimp May Hold Clues to Alien Life

Scientists at NASA’s Jet Propulsion Laboratory reveal that the extreme oasis of life deep in the Caribbean Sea may hold clues to life on other planetary bodies, including Jupiter’s moon Europa. At one of the world’s deepest undersea hydrothermal vents, tiny shrimp are piled on top of each other, layer upon layer, crawling on rock […]

Researchers Control a Material with Voltage

New research details how a MIT-based team has made important strides in the concept of using an electrical signal to control a magnetic memory. A new way of switching the magnetic properties of a material using just a small applied voltage, developed by researchers at MIT and collaborators elsewhere, could signal the beginning of a […]

Calorie-Restricting Diets Slow Aging

Neuroscientists show that calorie-reduced diets stop the normal rise and fall in activity levels of close to 900 different genes linked to aging and memory formation in mice. The adage ‘you are what you eat’ has been around for years. Now, important new research provides another reason to be careful with your calories. In a […]

Researchers Develop Nano Devices That Can be Propelled Through Media Similar to Bodily Fluids

Scientists from the Max Planck Institute have constructed swimming bodies that are small enough to be used in bodily fluids or even individual cells, and they are able to navigate through complex biological fluids. In the 1966 movie Fantastic Voyage, a submarine complete with crew is shrunk in size so that it can navigate through […]

Scientists Propose Benchmark for Better Replication of Natural Stem Cells

New research from UCLA establishes a standard to assess how conditions used to procure stem cells in the lab compare to those found in a human embryo, and could provide the foundation for scientists to more precisely replicate natural stem cell development in an artificial environment. The study, which was led by Guoping Fan, professor […]

Scientists Come Together to Reveal Cancer’s Strategies

In a new study, a group of scientists detail how they fused the power of statistical physics and artificial intelligence into a mathematical toolkit that can turn cancer-mutation data into multidimensional models that show how specific mutations alter the social networks of proteins in cells. While this may sound like the setup to some late-night […]

Special Coating Makes Batteries Safer

A new special coating developed by a team of researchers prevents electrical current from damaging the digestive tract after accidental battery ingestion. Every year, nearly 4,000 children go to emergency rooms after swallowing button batteries — the flat, round batteries that power toys, hearing aids, calculators, and many other devices. Ingesting these batteries has severe […]

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 […]
