CfA Scientists Measure the Rate of Expansion of the Universe

Using data from the Sloan Digital Sky Survey, CfA scientists examined 264,283 galaxies and measured the signature of the acoustic waves left behind. Perhaps the most astonishing and revolutionary discovery in cosmology was that galaxies are moving away from us. Hubble’s 1929 paper provides the underpinning of the big bang picture of creation in which […]

Study Reveals How and When Earth Developed Its Rigid Tectonic Plates

Newly published research from Yale University and Université de Lyon in France shows how and when Earth developed its rigid tectonic plates and why Venus never has. “We think it all comes down to the behavior of tiny grains of minerals within rocks,” said Yale geophysicist David Bercovici, lead author of research published online April […]

Researchers Uncover Mode of Action of New Multiple Sclerosis Drug

Scientists from the Max Planck Institute and the University of Lübeck have uncovered the mode of action for dimethyl fumarate, a drug that was recently approved in Europe as a basic therapy for multiple sclerosis. Just a few short weeks ago, dimethyl fumarate was approved in Europe as a basic therapy for multiple sclerosis. Although […]

Researchers Observe What Happens During a Quantum Phase Transition

In a newly published study, researchers observe what happens during a quantum phase transition, and compare the “quantum melting” of the magnetic structure with the classical “thermal melting” phase transition. When ice is warmed, the water molecules forming its structure vibrate more and more vigorously until finally the forces between them are no longer strong […]

Astronomers Ready for G2’s Encounter with Supermassive Black Hole Sgr A*

As the gas cloud, called G2, edges closer to the supermassive black hole Sgr A*, astronomers at Northwestern University are hoping to learn new information on growth of supermassive black holes. Evanston, Illinois — Right now a doomed gas cloud is edging ever closer to the supermassive black hole at the center of our Milky […]

Hubble Measures “El Gordo” Galaxy Cluster, Bigger Than Previously Thought

Researchers have measured the mass of the El Gordo Galaxy Cluster, calculating the cluster’s mass to be as much as 3 million billion times the mass of our sun. NASA’s Hubble Space Telescope has weighed the largest known galaxy cluster in the distant universe, cataloged as ACT-CL J0102-4915, and found it definitely lives up to […]

Fermi Data Reveal New Clues to Dark Matter

New maps from the Fermi-LAT Collaboration show that the galactic center produces more high-energy gamma rays than can be explained by known sources, suggesting that this excess emission is consistent with some forms of dark matter. A new study of gamma-ray light from the center of our galaxy makes the strongest case to date that […]

NASA Detects Ocean Inside Saturn’s Moon Enceladus

New data from NASA’s Cassini spacecraft and Deep Space Network provide the first geophysical measurements of the internal structure of Enceladus, suggesting that it harbors a large interior ocean beneath an ice shell. NASA’s Cassini spacecraft and Deep Space Network have uncovered evidence Saturn’s moon Enceladus harbors a large underground ocean of liquid water, furthering […]

Scientists Use ‘Smart Window’ to Observe Lithium-Ion Battery Operation

By using ultrathin sheets of smart-window material, nickel oxide, as the anode in a lithium-ion battery, researchers were able to see for first time exactly what happens when the battery’s lithium ions make contact with the nickel-oxide layer and how the resulting reaction spreads out from several different points. High-tech “smart windows,” which darken to […]

Astronomers View Shell of Escaping Material Around Sakurai’s Object

Using the Altair adaptive optics system with the Gemini North Telescope, two NOAO astronomers were able to observe the shell of escaping material around the star known as Sakurai’s Object (V4334 Sgr). Stellar lifetimes are measured in billions of years, so changes in their appearance rarely take place on a human timescale. Thus an opportunity […]

Astrophysicists Challenge the Cosmological Model

By comparing the predictions of state-of-the-art supercomputer simulations with the results of sophisticated statistical analyses of the cosmic background radiation, two independent studies are challenging the cosmological model. Astronomers Professor Chris Collins and Dr Ian McCarthy from LJMU’s Astrophysics Research Institute are challenging the view that the currently preferred cosmological model of the Universe is […]

MIT Researchers Reverse a Rare Liver Disorder in Mice

In a newly published study, MIT researchers show that a new gene-editing technique, known as CRISPR, can reverse a rare liver disorder caused by a single genetic mutation. Using a new gene-editing system based on bacterial proteins, MIT researchers have cured mice of a rare liver disorder caused by a single genetic mutation. The findings, […]
