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 […]

Astronomers Create First Cloud Map of a Planet Beyond Our Solar System

Astronomers Create First Cloud Map of a Planet Beyond Our Solar System

Astronomers used data from NASA’s Spitzer and Kepler space telescopes to produce a very low-resolution ‘map’ of the exoplanet Kepler-7b. Pasadena, California — Scientists using data from NASA’s Kepler and Spitzer space telescopes have created the first cloud map of a planet beyond our solar system, a sizzling, Jupiter-like world known as Kepler-7b. The planet […]

A New Hypothesis on the Nature of Black Holes

New Hypothesis on the Nature of Black Holes

In a newly published study, scientists present a new hypothesis on the nature of black holes, challenging the current “clean” black hole model. A black hole. A simple and clear concept, at least according to the hypothesis by Roy Kerr, who in 1963 proposed a “clean” black hole model, which is the current theoretical paradigm. […]

New Method Speeds up Stabilization of Chaotic Systems

A New Method Speeds Up Stabilisation of Chaotic Systems

A team of researchers has developed a new method to speed up the stabilization of chaotic systems. When chaos threatens, speed is essential; for example, when a pacemaker needs to stabilize an irregular heartbeat or a robot has to react to the information received from its environment. Both cases require imposing a stable, organized state […]

How to Distinguish Habitable Worlds Apart from Lifeless Gas Giants

Telling Habitable Worlds Apart from Lifeless Ones

A new study demonstrates how to distinguish between cloudy mini-Neptunes and volatile-dominated super-Earths based on the differences in the wing steepness and relative depths of water absorption features in moderate-resolution NIR transmission spectra (R~100). Perhaps the most intriguing exoplanets found so far are those bigger than our rocky, oceanic Earth but smaller than cold, gas-shrouded […]

Mitochondria Can Either Spur or Stop Obesity

Mitochondria Are the Key to Becoming Obese or Remaining Lean

In two newly published studies, researchers show how mitochondria play a key role in the body’s ability to control weight gain. Becoming obese or remaining lean can depend on the dynamics of the mitochondria, the body’s energy-producing “battery,” according to two new studies by Yale School of Medicine researchers featured as the cover story in […]

Observations Reveal How Interstellar Dust Grains Align

Astronomers Reveal Critical Interplay of Interstellar Dust and Hydrogen

In a newly published study, astronomers report key observations that confirm a theory on how dust grains in interstellar space spin and organize themselves in the presence of magnetic fields to precisely align in key astrophysical environments. For astrophysicists, the interplay of hydrogen — the most common molecule in the universe — and the vast […]
