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 […]

Highly Recurrent Mutations Discovered in “Dark Matter” of the Cancer Genome

A Human Melanoma Cell

Two newly discovered TERT promoter mutations were found to be even more common than BRAF mutations in melanoma, collectively occurring in 71% of the melanomas examined. Two mutations that collectively occur in 71 percent of malignant melanoma tumors have been discovered in what scientists call the “dark matter” of the cancer genome, where cancer-related mutations […]

Glial Cells Produce Neuregulin1 Promoting the Regeneration of Nerve Tissue

Glial Cells Assist in the Repair of Injured Nerves

New research with mice shows that the growth factor neuregulin1 supports nerve repair and the redevelopment of the myelin layer. Unlike the brain and spinal cord, the peripheral nervous system has an astonishing capacity for regeneration following injury. Researchers at the Max Planck Institute of Experimental Medicine in Göttingen have discovered that, following nerve damage, […]
