GC-1 Turns White Fat Into Brown Fat

Experimental Drug Turns White Fat Into Brown Fat

New research shows that the experimental drug GC-1 dramatically increases the metabolic rate, essentially converting white fat into a fat like calorie-burning brown fat. San Diego, California – An experimental drug causes loss of weight and fat in mice, a new study has found. The study results will be presented Friday at the Endocrine Society’s […]

Entanglement Can Improve Optical Sensor Performance

Entanglement Can Improve the Performance of Optical Sensors

A new study from MIT demonstrates that entanglement can improve the performance of optical sensors, even when it doesn’t survive light’s interaction with the environment. The extraordinary promise of quantum information processing — solving problems that classical computers can’t, perfectly secure communication — depends on a phenomenon called “entanglement,” in which the physical states of […]

Study Shows Bacterial Infection, C. dificile, Widespread in the United States

Bacterial Infection Widespread in the United States

Using population-based surveillance data, new research estimates that the germ Clostridium difficile caused nearly half a million infections in the United States in a single year. A new federal study estimates that the germ Clostridium difficile, more commonly known as C. difficile, caused nearly half a million infections in the United States in a single […]

Hubble Views Multiple Images of a Highly Magnified Supernova for the First Time

Hubble Sees Multiple Images of a Highly Magnified Supernova for the First Time

Using the Hubble Space Telescope, a team of astronomers has spotted four images of a distant exploding star for the first time. The images are arranged in a cross-shaped pattern by the powerful gravity of a foreground galaxy embedded in a massive cluster of galaxies. The supernova discovery paper appears in a special issue of […]

Hubble Image of the Week: The Mysteries of UGC 8201

Hubble Views Irregular Galaxy UGC 8201

This newly released Hubble image shows irregular galaxy UGC 8201, which is located roughly 15 million light-years away. The galaxy UGC 8201, captured here by the NASA/ESA Hubble Space Telescope, is a dwarf irregular galaxy, so called because of its small size and chaotic structure. It lies just under 15 million light-years away from us […]

EPFL Sheds New Light on the Fundamental Mechanisms of Heat Dissipation in Graphene

Researchers Shed New Light on the Fundamental Mechanisms of Heat Dissipation in Graphene

Scientists from École Polytechnique Fédérale de Lausanne shed new light on the fundamental mechanisms of heat dissipation in graphene and other two-dimensional materials. In the race to miniaturize electronic components, researchers are challenged with a major problem: the smaller or the faster your device, the more challenging it is to cool it down. One solution […]

Hypothalamic Agrp Neurons Also Control Compulsive Behaviors

Study Shows Hunger Neurons also Control Compulsive Behaviors

A newly published study from Yale University shows that in the absence of food Agrp neurons trigger foraging and repetitive behaviors in mice. In the absence of food, neurons that normally control appetite initiate complex, repetitive behaviors seen in obsessive-compulsive disorder (OCD), and anorexia nervosa, according to a new study by Yale School of Medicine […]

Yale Maps Evolutionary Changes of the Human Brain

Researchers Map Switches That Shaped the Evolution of the Human Brain

New research from Yale University reveals a detailed catalog of human-specific changes in gene regulation and pinpoints several biological processes potentially guided by these regulatory elements that are crucial to human brain development. Thousands of genetic “dimmer” switches, regions of DNA known as regulatory elements, were turned up high during human evolution in the developing […]

NASA’s Dawn Spacecraft Achieves Orbit Around Ceres

Dawn Spacecraft Becomes First to Orbit a Dwarf Planet

At 5:36 a.m. PST on March 6th, NASA’s Dawn spacecraft became the first mission to achieve orbit around a dwarf planet. The spacecraft was approximately 38,000 miles (61,000) kilometers from Ceres when it was captured by the dwarf planet’s gravity at about 4:39 a.m. PST (7:39 a.m. EST) Friday. Mission controllers at NASA’s Jet Propulsion […]

New Isotopic Measurements Reveal Mars Once Had More Water than Earth’s Arctic Ocean

Mars Had More Water than the Arctic Ocean

New measurements by researchers at NASA reveal that an ocean once covered approximately twenty percent of the Martian surface, making Mars is considerably wetter than many previous estimates and raising the odds for the ancient habitability of the Red Planet. A primitive ocean on Mars held more water than Earth’s Arctic Ocean, according to NASA […]

Merlin Protein Promotes Effective and Rapid Wound Healing

Merlin Promotes Rapid Wound Healing

New research from the Max Planck Institute details how the protein merlin regulates collective cell movement, promoting effective and rapid wound healing. Cells also follow a herd instinct, and they thereby communicate in a magical collective way. This is because a protein known as merlin, named after the mythical wizard of medieval England, plays an […]

New Circuits That Can Control Light and Sound

A New Way to Control Information by Mixing Light and Sound

A team of researchers has developed hybrid technologies that can control light and sound, allowing information to be stored, filtered, and manipulated with far greater efficiency. For once, slower is better in a new piece of technology. A Yale lab has developed a new, radio frequency processing device that allows information to be controlled more […]

The Senkyo Region of Titan

New Cassini Image of Titan

This new Cassini image was acquired at a distance of approximately 1.2 million miles and looks toward the Saturn-facing side of Titan. Named after a Japanese paradise, the Senkyo region of Titan (the dark area below and to the right of center) is a bit less welcoming than its namesake. With a very inhospitable average […]

Astronomers Identify a Quadruple Star System, 30 Ari

Researchers Identify a Quadruple Star System

Using the Robo-AO adaptive optics system and the PALM-3000 adaptive optics system, astronomers have identified a planet in a quadruple star system for only the second time. Growing up as a planet with more than one parent star has its challenges. Though the planets in our solar system circle just one star — our sun […]

Unusual Form of Cosmic Precipitation Can Affect the Growth and Evolution of Galaxies

Cosmic Showers Halt Galaxy Growth

New research based on x-ray data from Chandra shows how an unusual form of cosmic precipitation can affect the growth and evolution of galaxies, slowing down star formation in galaxies with giant black holes. This galaxy cluster comes from a sample of over 200 that were studied to determine how giant black holes at their […]

Scientists Discover a Gene for Brain Size

Scientists Identify a Gene for Human Brain Size

A team of researchers has identified for the first time a gene (ARHGAP11B) that is only present in humans and contributes to the reproduction of basal brain stem cells, triggering a folding of the neocortex. About 99 percent of human genes are shared with chimpanzees. Only the small remainder sets us apart. However, we have […]

Possible Signs of Progress in the Fight Against Parkinson’s

Signs of Progress Against Parkinson’s

By using induced pluripotent stem cells, researchers have markedly reduced the symptoms Parkinson’s disease in primates. Harvard Stem Cell Institute (HSCI) researchers at University-affiliated McLean Hospital have taken what they describe as an important step toward using the implantation of stem cell-generated neurons as a treatment for Parkinson’s disease. Ole Isacson and colleagues reported that […]
