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, […]

Researchers Find a Link between Poor Sleep, Memory Loss and Brain Deterioration

Poor Sleep in Old Age Prevents the Brain from Storing Memories

New research from UC Berkeley suggests that sleep disruption in the elderly, mediated by structural brain changes, represents a contributing factor to age-related cognitive decline. Berkeley — The connection between poor sleep, memory loss and brain deterioration as we grow older has been elusive. But for the first time, scientists at the University of California, […]

A Step Towards 2-D Devices, Hybrid Graphene/Hexagonal Boron Nitride

Graphene Hexagonal Boron Nitride

Researchers at Rice University have shown the ability to pattern a conductor (graphene) and insulator (hexagonal boron nitride) into a one-atom-thick hybrid of graphene and hexagonal boron nitride, an important step toward the creation of two-dimensional electronics. Rice University scientists have taken an important step toward the creation of two-dimensional electronics with a process to […]

Regular Aspirin Use Linked to Age-Related Macular Degeneration

Aspirin Use Increases the Risk of Age Related Eye Disease

A new study found that regular aspirin use is significantly associated with an increased incidence of neovascular AMD, a leading cause of blindness in older people. Researchers at the Center for Vision Research from the Westmead Millennium Institute for Medical Research (WMI), a close affiliate of the University of Sydney, have found that regular aspirin […]

Magnetized Outflows from Center of the Milky Way are Driven by Star-Formation Activity

A False Color Image of Our Milky Way

In a newly published study, a team of scientists from the Smithsonian Astrophysical Observatory suggest that the recently discovered twin lobes of gamma-ray emission protruding about 50,000 light-years above and below the plane of our Milky Way galaxy are driven by star-formation activity, not black-hole activity. Two years ago, CfA astronomers reported the discovery of […]

Hubble Views Open Cluster NGC 411

Open Cluster NGC 411

This composite image from NASA’s Hubble Space Telescope shows open cluster NGC 411, which is located in the Small Magellanic Cloud. Globular clusters are roughly spherical collections of extremely old stars, and around 150 of them are scattered around our galaxy. Hubble is one of the best telescopes for studying these, as its extremely high […]

Research Shows Frequent Multitaskers Overrate Their Ability

Multitaskers Are Bad at It

New research from the University of Utah shows that the people most likely to multitask have the lowest multitasking ability, including people who talk on cell phones while driving. Most people believe they can multitask effectively, but a University of Utah study indicates that people who multitask the most – including talking on a cell […]
