A Close Star System Discovered, Only 6.5 Light Years Away

Close Binary System Discovered

In a new research paper, Penn State researcher Kevin Luhman describes the discovery the third-closest star system to the Sun, WISE J104915.57-531906. Both stars in this newly discovered binary system are “brown dwarfs” and are located about 6.5 light years away. A pair of newly discovered stars is the third-closest star system to the Sun, […]

Scientists Discover an Outflow from a Young Protostar

A New Telescope Probes a Young Protostar IRAS 16293 2922B

Using the Atacama Large Millimeter/submillimeter Array, scientists discovered an outflow from a young protostar, marking a dramatic step towards understanding the earliest stages of a star’s life. IRAS 16293-2922B is a very young star – a protostar – perhaps only about ten thousand years old. Slightly smaller in mass than our Sun, it is still […]

Scientists Create a 3D View of the Ancient Water Channels of Mars

Visualization of Buried Marte Vallis Channels

Using data from NASA’s Mars Reconnaissance Orbiter, scientists create a 3D reconstruction of ancient water channels below the Martian surface. Pasadena, California — NASA’s Mars Reconnaissance Orbiter took numerous images during the past few years that showed channels attributed to catastrophic flooding in the last 500 million years. During this period, Mars had been otherwise […]

Telomere Length Predicts the Life Expectancy of Patients with Heart Disease

Length of DNA Strands in Patients With Heart Disease Can Predict Life Expectancy

In a new study, scientists were able to predict survival rates among patients with heart disease based on the length of strands of DNA found on the ends of chromosomes known as telomeres. San Francisco, California – Can the length of strands of DNA in patients with heart disease predict their life expectancy? Researchers from […]

Alzheimer’s Research Suggests Exposure to New Activities May Delay Onset of Dementia

Exposure to New Activities May Delay Onset of Alzheimers

In a new study, a team of scientists from the Harvard-affiliated Brigham and Women’s Hospital provide scientific evidence showing that exposure to new activities may delay onset of dementia from Alzheimer’s disease. Previous studies have shown that keeping the mind active, exercising, and social interactions may help delay the onset of dementia in Alzheimer’s patients. […]

Satellite Data Reveals a Shift in Vegetation Growth at Northern Latitudes

Climate Change Shifts Northern Growing Seasons

In a newly published study, scientists examined the relationship between changes in surface temperature and vegetation growth, finding that temperature and vegetation growth at northern latitudes now resemble those found at 4 degrees to 6 degrees of latitude farther south as recently as 1982. Vegetation growth at Earth’s northern latitudes increasingly resembles lusher latitudes to […]

Hubble Views Newborn Stars in Galaxy IC 5052

Hubble Views Blue Bursts of Hot Young Stars

In a new image, Hubble views the pale blue light of extremely hot newborn stars in barred spiral galaxy IC 5052. This image, speckled with blue, white and yellow light, shows part of the spiral galaxy IC 5052. Surrounded in the image by foreground stars in our own galaxy, and distant galaxies beyond, it emits […]

Researchers Discovered a Very Rare Type Ibn Supernova

Pan STARRS Finds a Lost Supernova

Using the Pan-STARRS telescope, researchers discovered a very rare Type Ibn supernova on the outskirts of an elliptical galaxy. Cambridge, Massachusetts – The star Eta Carinae is ready to blow. 170 years ago, this 100-solar-mass object belched out several suns’ worth of gas in an eruption that made it the second-brightest star after Sirius. That […]

Scientists Eliminate Lung Tumors by Inhibiting Myc

VHIO Scientists Eradicate Lung Tumors in Mice

In a pre-clinical mouse model, VHIO scientists eliminated lung tumors by inhibiting the protein Myc. Previous studies had already shown that Myc was a key protein in tumor development and had established how to inhibit Myc through gene therapy. This protein is involved in the development of diverse tumors and so Myc-targeted therapy could make […]

Nanoparticles Carrying Melittin Kill HIV

Nanoparticles Loaded with Melittin Kill HIV

In a newly published study, scientists from Washington University School of Medicine show how nanoparticles carrying melittin fuse with HIV, killing the virus and leaving surrounding cells unharmed. Nanoparticles carrying a toxin found in bee venom can destroy human immunodeficiency virus (HIV) while leaving surrounding cells unharmed, researchers at Washington University School of Medicine in […]
