New Genome Analysis Reveals Dozens of Cancer Triggers

New Genome Analysis Reveals Dozens of Cancer Triggers

A new analysis of little-explored regions of the human genome has revealed dozens of cancer triggers. A massive data analysis of natural genetic variants in humans and variants in cancer tumors has implicated dozens of mutations in the development of breast and prostate cancer, a Yale-led team has found. The newly discovered mutations are in […]

Double Star Fomalhaut System is Actually a Triple Star System

Double Star Fomalhaut System is Actually a Triple Star System

New research from scientists at the University of Rochester reveals that the Fomalhaut star system contains a third star, Fomalhaut C. The nearby star system Fomalhaut – of special interest for its unusual exoplanet and dusty debris disk – has been discovered to be not just a double star, as astronomers had thought, but one […]

ALMA Discovers a Protostar Surrounded by a Large Hot Gas Cloud

Astronomers Discover a Molecular Cloud around a Young Star

An international team of astronomers has observed an infrared dark cloud surrounding a baby star that is about ten times larger than those found around typical solar-mass baby stars. A large hot molecular cloud around a very young star was discovered by ALMA. This hot cloud is about ten times larger than those found around […]

Scientists Believe Mars Crater is the Remains of an Ancient Supervolcano

Eden Patera Basin on Mars Could Have Been Formed by an Explosive Volcanic Eruption

Based on images and topographic data, new research shows that the Eden Patera basin on Mars is a volcanic caldera, not an impact crater. Tucson, Arizona — A research project led by Joseph R. Michalski, Senior Scientist at the Planetary Science Institute, has identified what could be a supervolcano on Mars – the first discovery […]

Hubble Views Planetary Nebula NGC 2452

New Hubble Image of Planetary Nebula NGC 2452

This newly released Hubble image shows planetary nebula NGC 2452. This NASA/ESA Hubble Space Telescope image shows the planetary nebula NGC 2452, located in the southern constellation of Puppis. The blue haze across the frame is what remains of a star like our Sun after it has depleted all its fuel. When this happens, the […]

Astronomers View Distant Galaxy Powered by Primordial Hydrogen

Scientists Observe Distant Galaxy Powered by Cosmic Fuel

A newly published study details how astronomers detected cold streams of primordial hydrogen, vestigial matter left over from the Big Bang, fueling a distant star-forming galaxy in the early Universe. Kamuela, Hawaii — Astronomers have detected cold streams of primordial hydrogen, vestigial matter left over from the Big Bang, fueling a distant star-forming galaxy in […]

Updated Theory Details How Biomolecules Were Able to Form Inside Asteroids

New Theory to Explain How Biomolecules Were Once Able to Form Inside of Asteroids

In a newly published study, researchers at Rensselaer Polytechnic Institute reexamine the unipolar induction mechanism for heating asteroids, detailing how biomolecules were once able to form inside of asteroids. A new look at the early solar system introduces an alternative to a long-taught, but largely discredited, theory that seeks to explain how biomolecules were once […]

Better Protein Creation is the Key to Longevity for the Naked Mole Rat

Better Protein Creation is the Secret to Naked Mole Rats Longevity and Health

In a newly published study, University of Rochester researchers show that better constructed proteins are the key to the naked mole rat’s longevity and health. Naked mole rats have what any animal would want. They live long lives—about 30 years—and stay healthy until the very end. Now biologists at the University of Rochester have new […]

Scientists Use Partial Covariance Mapping to Probe Electron Dynamics

New Technique Traces Ejected Electrons Back to Atomic Shells

Using a technique called partial covariance mapping, scientists gain new insight into the dynamics of “hollow atom” formation. In a detailed study of how intense light strips electrons from atoms, researchers used an X-ray laser, SLAC’s Linac Coherent Light Source (LCLS), to measure and sort the ejected electrons and discover how this process takes place. […]

Astronomers Use Quasars to Help Navigate Spacecraft

Galaxy NGC 4438

Astronomers use quasars in a technique known as Delta-Differential One-Way Ranging to help achieve precise navigation of spacecraft in deep-space. Deep-space missions require precise navigation, in particular when approaching bodies such as Mars, Venus or a comet. How precise? It’s necessary to pinpoint a spacecraft 100 million kilometers from Earth to within 1 km. To […]

Stanford Scientists Are Developing a Mini-Microscope to Detect Cancer Cells

Scientists Build a Microscope to Detect Cancer Cells

Stanford scientists are developing a mini-microscope to noninvasively detect circulating tumor cells, allowing for earlier interventions. One of the cruelest truths about cancer is that even after you beat the disease, it can still come back to kill you. A tumor growing in the prostate gland, breast, or any other organ can shed cancerous cells […]

New Metabolic Pathway More Efficiently Converts Sugars into Biofuels

Engineers Develop New Metabolic Pathway to Convert Sugars into Biofuels

UCLA scientists have developed a new synthetic glycolytic pathway that converts all six glucose carbon atoms into three molecules of acetyl-CoA without losing any as carbon dioxide. UCLA chemical engineering researchers have created a new synthetic metabolic pathway for breaking down glucose that could lead to a 50 percent increase in the production of biofuels. […]
