Astronomers Record Detailed Measurements of the Inner Region of a Quasar Nucleus

first-detailed-measurements-of-the-inner-region-of-a-quasar-nucleus-at-submillimeter-wavelengths

Using four submillimeter telescopes working simultaneously around the globe, a team of astronomers from the Smithsonian Astrophysical Observatory and colleagues made the first detailed measurements of the inner region of a quasar nucleus at submillimeter wavelengths. Quasars are among the most powerful energy sources known — some are as luminous as one hundred thousand Milky […]

Captive Beluga Whale Was Able to Mimic Speech

beluga-water

When a beluga’s caretakers heard noises that sounded like garbled phrases emanating from its enclosure, they realized that the whale might be imitating the voices of its human handlers. The outbursts, originally described at a conference in 1985, began in 1984 and lasted for four years until the whale named NOC hit its sexual maturity. […]

Distant Quasar Ejects 2 Million Light-Year Long Jet of Cosmic Material

megaparsec-scale-jet

This extended jet of cosmic materials, traveling near light speed, emerged from a distant galaxy. The flow is almost 2 million light-years long, at least 20 times larger than the Milky Way. Astronomers published their findings in the Astrophysical Journal Letters. The outflow is coming from a distant quasar that was formed 6 billion years […]

Sediment Samples from Japanese Lake Extend Carbon Dating Timeline

bones-neanderthal-dating

Climate records from a Japanese lake will improve the accuracy of dating techniques, which will probably help shed light on some mysteries such as the extinction of the Neanderthals as well as paradoxes that have arisen due to dating. The scientists published their findings in the journal Science. Carbon dating is used to date any […]

Molecular Analysis of Dinosaur Osteocytes Indicates Presence of Endogenous Molecules

blood-cells-reacting-dinosaur

20 years ago, Mary Schweitzer discovered that she spotted the effects of what could only be described as a red blood cell in a slice of dinosaur bone. This seemed impossible, since organic remains weren’t supposed to be able to survive the fossilization process. Numerous tests indicated that the spherical structures were blood cells from […]

Disabling MicroRNAs Allows Mice to Regenerate White Cells and Platelets Depleted by Chemotherapy

researchers have identified a method to help cancer patients maintain a healthy blood supply

Using a novel technique to analyze simultaneously large numbers of microRNAs in living mice, scientist at Yale University identified and disabled miR-150, allowing mice to more efficiently regenerate white cells and platelets depleted by chemotherapy. Chemotherapy kills blood cells as well as cancer cells, often with fatal results. Now Yale stem cell researchers have identified […]

Brain Scans Help Scientists Read Dreams

functional-neuroimaging

A team of Japanese researchers have been working on using neuroimaging techniques to decode the dreams of people while they sleep. The researchers were led by Yukiyasu Kamitani of the ATR Computational Neuroscience Laboratory in Kyoto, Japan and they used functional neuroimaging to scan the brains of patients. This technique allowed scientists to learn how […]

Elliptical Galaxy M87 Hides a Gaseous Spiral at its Core

elliptical-galaxy-M87

Scientists at the National Astronomical Observatory of Japan & Harvard-Smithsonian Center for Astrophysics discovered that elliptical galaxy Centaurus A also shows signs of a spiral galaxy. Cambridge, Massachusetts – Most big galaxies fit into one of two camps: pinwheel-shaped spiral galaxies and blobby elliptical galaxies. Spirals like the Milky Way are hip and happening places, […]

Kilauea’s Halema’uma’u Lava Lake At Highest Level

lava-lake-kilauea

The state of the lava lake in the Halema’uma’u Crater at Kilauea is now at its highest level since its formation in 2008, reaching 50 meters from the floor of the crater and now covering the inner ledge. The large Hawaiian shield volcano has a caldera at the summit. Unlike more catastrophic formations, the ones […]

Fossils Reveal Headbutts May Have Been Used as a Dinosaur Courtship Behavior

pachycelphalosaurus-wyomingensis

Pachycephalosaurids had domed heads with thick, bony protuberances, which paleontologists hypothesized the dinosaurs used in courtship behavior, perhaps to determine which male would be allowed to mate. A new study indicates that these dinosaurs might have been bashing themselves in a number of different ways. The scientists presented their findings at the Society of Vertebrate […]

NASA Discovers a Surprising Trend in Galaxy Evolution

Surprising Trend in Galaxy Evolution

A newly published study shows that nearby disk galaxies unexpectedly reached their current state long after much of the universe’s star formation had ceased. A comprehensive study of hundreds of galaxies observed by the Keck telescopes in Hawaii and NASA’s Hubble Space Telescope has revealed an unexpected pattern of change that extends back 8 billion […]

It seems that the blood of the young can help the old. A new study shows that when the blood of young mice is injected into the old, some of the effects of age-related cognitive decline are reversed. The scientists presented their findings at the Society for Neuroscience Conference in New Orleans, Louisiana. The blood […]

New Image of Polar Ring Galaxy NGC 660

NGC 660

A new image of ring galaxy NGC 660, which is located about 40 million light-years from Earth toward the constellation Pisces, was released by the Gemini Observatory. When the lamp is shattered, The light in the dust lies dead. When the cloud is scattered, The rainbow’s glory is shed. These words, which open Shelley’s poem […]

A rare species of ibis is part of a large European conservation effort, and the leading bird in this project was killed last weekend by illegal hunters in Italy. Goja, a northern bald ibis (Geronticus eremita), was in transit to her wintering grounds in Tuscany when she was shot down. G. eremita has been extinct […]

Indoor Concentrations of CO2 Can Impair Decision-Making Performance

Carbon Dioxide Impairs Decision-Making Performance

A recently published study from scientists at the Berkeley Lab, in collaboration with researchers at SUNY Upstate Medical University, found that moderately high indoor concentrations of CO2 can significantly impair people’s decision-making performance. Overturning decades of conventional wisdom, researchers at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have found that moderately high […]
