Astronomers Discover a New Method to Measure Supermassive Black Holes

New Method of Measuring the Mass of Supermassive Black Holes

In a newly published study, an international team of scientists detail the discovery of a new way to measure the mass of supermassive black holes, possibly allowing scientists to estimate black-hole masses in hundreds of galaxies in the local Universe. In a letter to Nature, a team of astronomers, including Marc Sarzi from the University […]

3D Microchip Allows Information to Travel in Three Dimensions

3D Microchip Created

Researchers at the University of Cambridge have created a new type of microchip that allows information to move in three dimensions, left to right, back to front and up and down. Scientists from the University of Cambridge have created, for the first time, a new type of microchip which allows information to travel in three […]

Unusual Protostar Periodically Emits Infrared Light Bursts

Hungry Twin Stars Gobbling Their First Meals

Using data from the Spitzer Space Telescope, researchers observed an unusual protostar that periodically emits infrared light bursts, becoming 10 times brighter every 25.34 days, and suggest that the pulsed accretion may be associated with an unseen binary companion. Amherst, Massachusetts – Just-forming stars, like growing babies, are always hungry and must “feed” on huge […]

A Vegetarian Diet Could Reduce People’s Risk of Heart Disease by up to 32%

Vegetarianism Can Reduce the Risk of Heart Disease By Up to a Third

New research from the University of Oxford suggests that a vegetarian diet could significantly reduce people’s risk of heart disease, finding that vegetarians have up to 32% less risk of developing heart disease than comparable non-vegetarians. Heart disease is the single largest cause of death in developed countries, and is responsible for 65,000 deaths each […]

Researchers Identify a Superbug’s Secret to Antibiotic Resistance

Staphylococcus Aureus

Fighting to stop deadly infections like Staphylococcus aureus, scientists have now identified the structural basis for antibiotic multiresistance acquisition by S. aureus and suggest ways to potentially stop the transfer. Worldwide, many strains of the bacterium Staphylococus aureus are already resistant to all antibiotics except vancomycin. But as bacteria are becoming resistant to this once […]

TW Hydrae has Enough Mass to Make the Equivalent of 50 Jupiters

TW Hydrae

Scientists believe the disk of material surrounding the 10 million year old star called TW Hydrae may be large enough to create an exotic planetary system with larger and more numerous planets than our own solar system. Pasadena, California — A star thought to have passed the age at which it can form planets may, […]

Researchers Retrieve Water and Sediment Samples from Subglacial Lake Whillans

Scientists Believe an Aquatic System is Buried Beneath the Antarctic Ice Sheet

A NSF funded research team has reached a subglacial lake and retrieved water and sediment samples that may contain microscopic life that has been isolated from direct contact with the atmosphere for thousands of years. In a first-of-its-kind feat of science and engineering, a National Science Foundation (NSF)-funded research team has successfully drilled through 800 […]

Beer’s Bitter Compounds May Result in New Treatments for Diabetes and Other Maladies

Humulone Molecule

Using a process called X-ray crystallography, scientists at the University of Washington have determined the precise configuration of humulones, which may result in new pharmaceuticals to treat diabetes, some types of cancer and other maladies. Researchers employing a century-old observational technique have determined the precise configuration of humulones, substances derived from hops that give beer […]

Evidence Against the Hypothesis that a Comet Impact Wiped Out Prehistoric Humans

Prehistoric Humans Were Not Wiped Out By a Comet

New research provides evidence against the hypothesis that a large comet impact or airburst caused the termination of the Clovis culture. Comet explosions did not end the prehistoric human culture, known as Clovis, in North America 13,000 years ago, according to research published in the journal Geophysical Monograph Series. Researchers from Royal Holloway, together with […]

LCLS X-Ray Laser Captures Electron ‘Dance’

A Molecular Model Representing Ferreous Bipyridine

Using the LCLS X-ray laser, researchers have demonstrated the ability to manipulate and study ultrafast energy transfers using a technique called X-ray absorption spectroscopy. The way electrons move within and between molecules, transferring energy as they go, plays an important role in many chemical and biological processes, such as the conversion of sunlight to energy […]

Sexual Frequency between Married Couples Linked to Household Chores

More Sex for Married Couples

A new study from the University of Washington shows that sex between married couples is linked to what types of chores each spouse completes. Married men and women who divide household chores in traditional ways report having more sex than couples who share so-called men’s and women’s work, according to a new study co-authored by […]

The Abell 901/902 Supercluster of Galaxies

The Abell 901 902 Supercluster of Galaxies

This ESO picture of the week shows the region around the Abell 901/902 supercluster of galaxies. It was created from images forming part of the Digitized Sky Survey 2. This deep-field image shows what is known as a supercluster of galaxies — a giant group of galaxy clusters which are themselves clustered together. This one, […]
