Researchers Find a New Target to Treat a Wide Spectrum of Cancers

New Target for Treating Wide Spectrum of Cancers

By using a computational method to capture the various shapes of the p53 protein, a protein that is implicated in nearly 40 percent of diagnosed cancer cases, scientists have identified a way to target the protein with cancer-fighting drugs. UC Irvine biologists, chemists and computer scientists have identified an elusive pocket on the surface of […]

Asteroid to Make a Record Close Approach to Earth on February 15

Passage of Asteroid 2012 DA14 Through the Earth Moon System

According to NASA data, a 45 meter asteroid named 2012 DA14 will make a record close approach for a known object of this size to Earth on February 15, passing inside the ring of geosynchronous weather and communications satellites. The small near-Earth asteroid 2012 DA14 will pass very close to Earth on February 15, so […]

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 […]

Astronomers Discover a New Method to Measure Supermassive Black Holes

New Method of Measuring the Mass of Supermassive Black Holes

In a newly published study, an international team of scientists detail the discovery of a new way to measure the mass of supermassive black holes, possibly allowing scientists to estimate black-hole masses in hundreds of galaxies in the local Universe. In a letter to Nature, a team of astronomers, including Marc Sarzi from the University […]
