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 […]

In a new report published this week by Michigan State University’s psychology department, researchers found evidence that using multiple forms of media at the same time is linked to symptoms of anxiety and depression. The study was conducted with data from two surveys of 319 undergraduate students, a group of people who engage in a […]

European Catfish Learn to Catch Pigeons

predatory-catfish-pigeons

A group of European catfish in Southwestern France have learned to catch pigeons, as they get close to the River Tarn. European catfish (Silurus glanis) can grow up to 1 to 1.5 meters long and are the largest freshwater fish in Europe. The scientists published their findings in the journal PLOS ONE. S. glanis accomplishes […]

Study Shows that Genetics Play an Important Role in Anti-Tobacco Policies

smokers have biological resistance to anti-tobacco policies

A newly published study from Yale University suggests that genetics play an important role in whether a person responds to tobacco-control policies, finding that people who are genetically predisposed to tobacco addiction were not dissuaded from smoking despite concerted government efforts to curtail tobacco use. Despite concerted government efforts to curtail tobacco use, the number […]

WISE Spots Massive Distant Galaxy Cluster

WISE Finds a Galaxy cluster

Using NASA’s Wide-field Infrared Survey Explorer (WISE), astronomers discovered a distant galaxy cluster, MOO J2342.0+1301, which is located 7.7 billion light-years away and is hundreds of times more massive than our Milky Way. Our solar system, with its colorful collection of planets, asteroids and comets, is a fleck in the grander cosmos. Hundreds of billions […]

Scattered Silver Cubes Scale Up Light Absorption for Solar Power

silver-nanocube-sprinkles

Nanoscale cubes of silver could help make more efficient solar panels, heat detectors and specialist cameras. The randomly scattered cubes were placed on pieces of polymer-coated metals to form a device that absorbs nearly all light that hits it. The scientists published their findings in the journal Nature. Unlike other light absorbers, it’s relatively simple […]
