Maggots Secretions Suppress Immune Response

maggots-heal-wounds

Researchers have figured out how fly larvae works as a healing balm that’s been used by battlefield surgeons for centuries to close wounds. The scientists published their findings in the journal Wound Repair and Regeneration. Maggots suppress the immune system. They consume dead tissue, leaving healthy tissue practically unscathed. Physicians have been using larvae to […]

Using Urine to Make Brain Cells

brain-cells-induced-pluripotency

Urine could be used as a powerful source of brain cells to study some disease, and could even be used one day in therapies to study neurodegenerative diseases. Scientists have found a way to persuade the cells discarded in urine to turn into useful neurons. The scientists published their findings in the journal Nature Methods. […]

Lonely People Experience Vasoconstriction Making Them Colder

winter-cold

When people feel lonely, or when someone is being excluded by others, the person’s skin becomes colder. This is how people respond to exclusion and other social interactions. The scientists published their findings in the journal Acta Psychologica. Dozens of students were asked to participate in a simulated ball-tossing game with computer-generated avatars. While they […]

Image Shows Galaxy Cluster “Tails”

Two tails of X-ray emission have been seen trailing behind a galaxy

A composite image shows two “tails” that were created when cool gas from ESO 137-001 was stripped by hot gas as it travels towards the center of the galaxy cluster Abell 3627. Two spectacular tails of X-ray emission have been seen trailing behind a galaxy using the Chandra X-ray Observatory. A composite image of the […]

Shallow Undersea Methane Hydrate Deposit Found in Arctic

arctic-drilling-beaufort

In the Arctic Circle, on the continental slope off Canada in the Beaufort Sea, the shallowest known deposit of methane hydrate has been discovered. The crystalline solid is comprised of methane molecules trapped in an ice-lattice structure. The scientists presented their findings at the annual meeting of the Geophysical Union in San Francisco, California. The […]

Brain Pacemaker Implanted to Treat Alzheimer’s

Brain Pacemaker

In November, researchers at Johns Hopkins Medicine implanted a pacemaker-like device into the brain of a patient in the early stages of Alzheimer’s disease. This device provides deep brain stimulation and has been used in thousands of people with Parkinson’s disease. It is seen as a possible way of boosting memory and reversing cognitive decline. […]

Disk Around Protostar L1527 IRS Behaves like a Proto Solar-System

the disk around this young star behaves just like a proto solar-system

Using the Submillimeter Array and another radio telescope to study the disk around protostar L1527 IRS, astronomers were able to measure properties of the circumstellar disk, discovering that the disk behaves just like a proto solar-system. Astronomers estimate that once the Sun began to shine it took the Earth another 50-100 million years to grow […]

Changes in the Andes Cause Flood Risks for South American Cities

bogota-skyline-andes

At more than 11,000 feet above sea level, very important ecosystems known as páramos exist. These kinds of ecosystems are only found in Central and South America and resemble a sort of alpine archipelago, each a link between distinct island ecosystems that exist nowhere else on the planet. These páramos play a crucial role in […]

Hubble Views Spiral Galaxy NGC 922

hubble views spiral galaxy NGC 922

This new Hubble image shows spiral galaxy NGC 922, which is located about 157 million light years from Earth and was formed by the collision between two galaxies. Bright pink nebulae almost completely encircle a spiral galaxy in this NASA/ESA Hubble Space Telescope image of NGC 922. The ring structure and the galaxy’s distorted spiral […]

Carbon Locked in Arctic Permafrost Will Contribute to Global Warming

arctic-permafrost

Fresh concerns are being expressed about the carbon locked in the Arctic’s permafrost. New studies presented at the American Geophysical Union quantify the amount of soil carbon at about 1.9 trillion metric tons, indicating that previous estimates underestimated the climate risk if this carbon is released due to warming temperatures. New laboratory experiments that are […]

Nanodevice Can Focus Light into a Point Just a Few Billionths of a Meter Across

device that can focus light into a point just a few nanometers across

Scientists at Caltech have created a new kind of waveguide. Made of amorphous silicon dioxide and covered in a thin layer of gold, the nanodevice can focus light into a point just a few nanometers across. Pasadena, California — As technology advances, it tends to shrink. From cell phones to laptops—powered by increasingly faster and […]

The Quantum Teleportation Race Goes Into Space in 2016

quantum-teleportation-space-race

Three years ago, Jian-Wei Pan and his colleagues were able to quantum teleport information across 16 kilometers. This was one of the first major steps to the research team’s ultimate goal of teleporting photons to a satellite orbiting the Earth. Once this is achieved, it will establish the first links of the quantum Internet, which […]
