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, […]

Body’s Natural Inflammatory Response Linked to the Spread of Breast Cancer

How Cancer Cells Spread Through the Bloodstream

Biomedical engineers at Cornell University have discovered a link between the body’s natural inflammatory response and how malignant breast cancer cells use the bloodstream to metastasize, suggesting that therapeutic approaches targeting cytokine receptors and adhesion molecules on cancer cells may potentially reduce metastatic load and improve current cancer treatments. Cancer is lethal because it spreads, […]

Scientists View Changes in Venus’s Ionosphere

Comet Like Ionosphere at Venus

Scientists were able to study the deformation of the sheath of electrons and ions enveloping Venus for the first time. In rare events, the sheath of electrons and ions enveloping Venus in a height of 150 to 300 kilometers can expand into space like a tail. This exceptional deformation occurs on the planet’s night side, […]

Researchers Identify Mutations Responsible for USC Tumors

Researchers Identify Mutations Responsible for USC Tumors

Scientists from Yale University have clearly identified the mutations that are responsible for uterine serous carcinoma (USC) tumors, a finding that could lead to new treatment opportunities. In a major breakthrough for uterine serous carcinoma (USC) — a chemo-resistant, aggressive form of endometrial cancer, Yale researchers have defined the genetic landscape of USC tumors, findings […]

DARPA Announces the Vanishing Programmable Resources Program

DARPA Announces the Vanishing Programmable Resources Program

DARPA’s Vanishing Programmable Resources program seeks to develop electronics capable of dissolving into the environment around them when triggered to do so. The sophisticated electronics used by warfighters in everything from radios, remote sensors and even phones can now be made at such a low cost that they are pervasive throughout the battlefield. These electronics […]

Shedding Light on the Role of Forests in Carbon Sequestration

A Mortality Map of the Amazon Near Manaus

Researchers at Berkeley Lab have developed an analytical method that combines satellite images, simulation modeling and fieldwork to help detect forest mortality patterns and trends, helping scientists understanding of the role of forests in carbon sequestration and the impact of climate change. The Earth’s forests perform a well-known service to the planet, absorbing a great […]

Superbubble DEM L50

Image of DEM L50

This new composite image from NASA’s Chandra X-ray Observatory shows superbubble DEM L50, which is located in the Large Magellanic Cloud about 160,000 light years from Earth. Superbubbles are found in regions where massive stars have formed in the last few million years. The massive stars produce intense radiation, expel matter at high speeds, and […]
