Solution to the Coronal Heating Mystery Presented at 2015 TESS Meeting

Solution to the Coronal Heating Mystery Presented

Researchers detail why the sun’s atmosphere is so much hotter than its surface, revealing that the heating mechanism depends on regular, but intermittent explosive bursts of heat, rather than on continuous gradual heating. The sun’s surface is blisteringly hot at 10,340 degrees Fahrenheit — but its atmosphere is another 300 times hotter. This has led […]

Astronomers Reveal “Missing-Link” in the Supernova-GRB Connection

Missing-Link in the Supernova-GRB Connection

A newly published study details the “missing link” between supernova explosions that generate gamma-ray bursts (GRBs) and those that don’t. Cambridge, Massachusetts – Astronomers using the National Science Foundation’s Very Large Array (VLA) have found a long-sought “missing link” between supernova explosions that generate gamma-ray bursts (GRBs) and those that don’t. The scientists found that […]

Modern Humans Triggered the Demise of Neanderthals

Scientists Decipher the Demise of Neandertals

A newly published study reveals that Homo sapiens belonging to the Protoaurignacian culture may have been the ultimate cause for the demise of Neanderthals. Researchers from the University of Bologna, Italy, and the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, analyzed two deciduous teeth from the prehistoric sites of Grotta di Fumane and […]

Nearby Star-Forming Galaxies Can Form Massive Black Holes

Black Hole Hunters Tackle a Cosmic Conundrum

New research shows that a supermassive black hole exists in a place where it isn’t supposed to be, opening a new door to understanding what things were like as the universe evolved and grew in the depths of time. Supermassive black holes, the mysterious monsters that sit at the center of galaxies—the Milky Way included—were […]

Targeting Brain Metastases with Stem Cell Therapy

Targeting Breast to Brain Metastatic Tumor

Researchers have developed an in vivo imageable breast-to-brain metastasis mouse model. Using real time in vivo imaging and subsequent composite fluorescence imaging, they show a widespread distribution of micro- and macro-metastasis in different stages of metastatic progression. Harvard Stem Cell Institute (HSCI) researchers at Massachusetts General Hospital (MGH) have developed an “imageable” mouse model of […]

Neuroscientists Show How Brain Cells Control the Flood of Information

Controlling the Thalamus with Dynamic Synapses

Neuroscientists from Brown University show how cells in the brain’s cortex can either stifle or enhance sensory information incoming from the thalamus, thereby allowing it to focus on just some of the many sensory inputs it might choose to consider. Providence, Rhode Island (Brown University) — We consider only some of the sights, sounds, and […]

The First Complete View of the Yellowstone Magmatic System

Newly Discovered Yellowstone Reservoir of Partly Molten Rock is Four Times Bigger than Shallower Chamber

A newly published study provides the first complete view of the Yellowstone magmatic system from the mantle plume to the upper crust, revealing a gigantic magma reservoir beneath the previously known magma chamber. University of Utah seismologists discovered and made images of a reservoir of hot, partly molten rock 12 to 28 miles beneath the […]

FDA Approved Tapeworm Drug Shows Promise Against MRSA

Tapeworm Medication Shows Promise Against MRSA

New research from Brown University and Rhode Island Hospital reveal that a common tapeworm drug (which is already approved for use in humans) effectively treated MRSA superbugs in lab cultures and in infected nematode worms. Providence, Rhode Island (Brown University) — A new study provides evidence from lab experiments that a drug already used in […]

Implantable Device Allows Doctors to Identify the Best Chemotherapy Agents

Implantable Device Tests Cancer Drugs in Patients

A team of engineers has developed a new implantable device that will allow doctors to test the effectiveness of cancer drugs and to identify drugs that work best for each patient prior to starting systemic administration of chemotherapy. More than 100 drugs have been approved to treat cancer, but predicting which ones will help a […]

Astronomers Discover 11 Runaway Elliptical Galaxies

Astronomers Find Runaway Galaxies

Astronomers from the Harvard-Smithsonian Center for Astrophysics and Moscow State University have discovered 11 isolated compact elliptical galaxies that have been flung out of their homes to wander the void of intergalactic space. Cambridge, Massachusetts – We know of about two dozen runaway stars, and have even found one runaway star cluster escaping its galaxy […]

Scientists Provide Novel Tools to Study Enzyme Catalysis

Controlling Enzyme Reactions at Atomic Level

A newly published study details how scientists used a chemical probe to dissect individual catalytic steps of enoyl-thioester reductases, validating an active site tyrosine as the cryptic proton donor and explaining how it had eluded definitive identification. Enzymes are naturally existing biocatalysts of great potential for application in sustainable chemistry. Yet, controlling enzyme reactions at […]
