Movement through Dark Matter Perturbs Comet Orbits and Increases Heating in Earth's Core

Research by New York University Biology Professor Michael Rampino concludes that Earth's infrequent but predictable path around and through our Galaxy's disc may have a direct and significant effect on geological and biological phenomena occurring on Earth. In a new paper in Monthly Notices of the Royal Astronomical Society, he concludes that movement through dark matter may perturb the orbits of comets and lead to additional heating in the Earth's core, both of which could be connected with mass extinction events.

Generating, Characterizing Randomness Fundamentally Important in Quantum Information Science

The article by CQP Researchers Dr Jonathan Matthews, Beccie Whittaker, Professor Jeremy O'Brien and Dr Peter Turner; discusses how generating and characterizing randomness is fundamentally important in both classical and quantum information science.

No Brown Dwarf Orbits Unusual Double Star V471 Tauri

Some pairs of stars consist of two normal stars with slightly different masses. When the star of slightly higher mass ages and expands to become a red giant, material is transferred to other star and ends up surrounding both stars in a huge gaseous envelope. When this cloud disperses the two move closer together and form a very tight pair with one white dwarf , and one more normal star.

Black Hole Growth Somehow Influenced by the Invisible Hand of Dark Matter

Every massive galaxy has a black hole at its center, and the heftier the galaxy, the bigger its black hole. But why are the two related? After all, the black hole is millions of times smaller and less massive than its home galaxy.

Spin Filters Within Magnetic Sandwiches Influence Tunnel Magnetoresistance

Measurements at BESSY II have shown how spin filters forming within magnetic sandwiches influence tunnel magnetoresistance – results that can help in designing spintronic components.

PSI Swiss Light Source Generates Light with Properties Similar to SwissFEL X-Ray Laser

For many years, PSI researchers have been testing experimental methods that will provide insights into novel materials for electronic devices. Using a special trick to make the Swiss Light Source (SLS) at PSI generate light with similar properties to that of PSI's x-ray laser SwissFEL, the researchers were able to demonstrate that the experiments planned for SwissFEL are possible and they are now building an experimental station at SwissFEL.

Latest Planck Data Supports Mindboggling Expansion of the Universe During its First Moments

From its orbit 930,000 miles above Earth, the Planck space telescope spent more than four years detecting the oldest light in the universe, called the cosmic microwave background.

Solar Telescope Combined with Laser Frequency Comb May Help Hunt Exoplanets

The hunt for Earth-like planets around distant stars could soon become a lot easier thanks to a technique developed by researchers in Germany. In a paper published today, 18 February, in the Institute of Physics and German Physical Society's New Journal of Physics, the team of researchers have successfully demonstrated how a solar telescope can be combined with a piece of technology that has already taken the physics world by storm--the laser frequency comb (LFC).

Recently Discovered Dim Star Could Have Passed Through the Solar System's Oort Cloud

A group of astronomers from the US, Europe, Chile and South Africa have determined that 70,000 years ago a recently discovered dim star is likely to have passed through the solar system's distant cloud of comets, the Oort Cloud. No other star is known to have ever approached our solar system this close - five times closer than the current closest star, Proxima Centauri.

High Plume Could Pose a Hazard for Low-Orbit Missions to Mars

In March 2012 amateur astronomers in different corners of the world gathered images of a plume emerging at dawn on the edge of the disc of Mars. Even though spacecraft orbiting Mars have on numerous occasions observed thin cloud layers on the limb, the maximum altitude of these layers has never exceeded 100 km.
