Researchers Move Closer to Preventing Alzheimer’s Disease

A Treatment to Prevent Alzheimers Disease is a Step Closer

Scientists at the University of Lancaster have developed a new drug that may help prevent the early stages of Alzheimer’s disease by reducing the number of senile plaques and increasing the number of new nerve cells in a region of the brain associated with memory. A new drug to prevent the early stages of Alzheimer’s […]

Hubble Views a Galaxy in a Transitional Phase

Young Star Forming Galaxies Settle to Become Massive Red and Dead Galaxies

The Hubble Space Telescope captured an image of the transitional phase when young, star-forming galaxies settle to become massive, red and dead galaxies. The further away you look, the further back in time you see. Astronomers use this fact to study the evolution of the Universe by looking at nearby and more distant galaxies and […]

An Updated Model for Identifying Habitable Zones Around Stars

A Model for Identifying Habitable Zones Around Stars

Scientists at Penn State have developed an updated model for determining whether discovered planets fall within a habitable zone. University Park, Pennsylvania — Researchers searching the galaxy for planets that could pass the litmus test of sustaining water-based life must find whether those planets fall in what’s known as a habitable zone. New work, led […]

Berkeley Lab Develops a Computational Pipeline to Analyze Tumor Images

A Tumors Organizational Complexity is Revealed

Scientists at Berkeley Lab have developed an algorithm and a computational pipeline that combs through large sets of images and identifies tumor subtypes, helping shed light on whether tumor subtype can predict the effectiveness of therapies and allowing scientists to learn more about the genetic and molecular mechanisms that control tumor signatures. How’s this for […]

Growing Graphene Without the Defects

Defect Free Graphene

Scientists at the University of Oxford have developed a new way of growing graphene without the defects that weaken it and prevent electrons from flowing freely within it, possibly opening the doorway to large-scale manufacturing of graphene-based devices for electronics, energy, and healthcare. A team led by Oxford University scientists has overcome a key problem […]

“Cosmic Web Stripping” – A New Way of Explaining the Lack of Observed Dwarf Galaxies

Lack of Observed Dwarf Galaxies

An international team of researchers have identified “Cosmic Web Stripping” as a new way of explaining the lack of observed dwarf galaxies as compared with that predicted by the theory of Cold Dark Matter and Dark Energy. High-precision observations over the last two decades have indicated that our Universe consists of about 75% Dark Energy, […]

First Artificial Enzyme Created by in Vitro Directed Evolution

First Artificial Enzyme Created by Evolution in a Test Tube

Using a noncatalytic protein scaffold, a team of researchers at the University of Minnesota have generated the first artificial enzyme created by in vitro directed evolution. The new study notes that the artificial RNA ligase enzyme lost its original fold and adopted an entirely new structure with substantially enhanced conformational dynamics, demonstrating that a primordial […]

Storm Spawns the Largest Tropospheric Vortex Ever Seen on Saturn

Cassini Spacecraft Shows a Giant Storm on Saturn

Using data from NASA’s Cassini spacecraft, scientists analyzed a massive storm on Saturn. The storm was the longest-lasting ever recorded on Saturn and it spawned the largest tropospheric vortex ever seen there. Call it a Saturnian version of the Ouroboros, the mythical serpent that bites its own tail. In a new paper that provides the […]

Biologists Pinpoint Individual Neurons in the Skin that React to Massage-like Stimuli

Individual Neurons in the Skin React to Massage

In a new study working with mice, biologists at Caltech were able to pinpoint individual neurons that were activated by massage-like stroking of the skin. Pasadena, California — The skin is a human being’s largest sensory organ, helping to distinguish between a pleasant contact, like a caress, and a negative sensation, like a pinch or […]

Unusual Protostar Periodically Emits Infrared Light Bursts

Hungry Twin Stars Gobbling Their First Meals

Using data from the Spitzer Space Telescope, researchers observed an unusual protostar that periodically emits infrared light bursts, becoming 10 times brighter every 25.34 days, and suggest that the pulsed accretion may be associated with an unseen binary companion. Amherst, Massachusetts – Just-forming stars, like growing babies, are always hungry and must “feed” on huge […]

A Vegetarian Diet Could Reduce People’s Risk of Heart Disease by up to 32%

Vegetarianism Can Reduce the Risk of Heart Disease By Up to a Third

New research from the University of Oxford suggests that a vegetarian diet could significantly reduce people’s risk of heart disease, finding that vegetarians have up to 32% less risk of developing heart disease than comparable non-vegetarians. Heart disease is the single largest cause of death in developed countries, and is responsible for 65,000 deaths each […]

Researchers Identify a Superbug’s Secret to Antibiotic Resistance

Staphylococcus Aureus

Fighting to stop deadly infections like Staphylococcus aureus, scientists have now identified the structural basis for antibiotic multiresistance acquisition by S. aureus and suggest ways to potentially stop the transfer. Worldwide, many strains of the bacterium Staphylococus aureus are already resistant to all antibiotics except vancomycin. But as bacteria are becoming resistant to this once […]

TW Hydrae has Enough Mass to Make the Equivalent of 50 Jupiters

TW Hydrae

Scientists believe the disk of material surrounding the 10 million year old star called TW Hydrae may be large enough to create an exotic planetary system with larger and more numerous planets than our own solar system. Pasadena, California — A star thought to have passed the age at which it can form planets may, […]
