Scientists Discover New Asymmetric Topological Insulator

Scientists Discover New Asymmetric Topological Insulator

A team of scientists has discovered a new asymmetric topological insulator made of many layers of BiTeCl, which enables electrical current to flow differently along its top surface than along its bottom. Scientists working at SLAC, Stanford, Oxford, Berkeley Lab and in Tokyo have discovered a new type of quantum material whose lopsided behavior may […]

New Cassini Image of Saturn’s Rings and Moons

Cassini Spacecraft Views the Moons of Saturn

This new image from the Cassini spacecraft shows Saturn’s rings and five of its moons. Five moons pose for the international Cassini spacecraft to create this beautiful portrait with Saturn’s rings. This view, from 29 July 2011, looks toward the northern, sunlit side of the rings from just above the ringplane. At the far right, […]

Researchers Discover New Ligament in the Human Knee

Researchers Detail New Ligament in the Human Knee

Using macroscopic dissection techniques on cadavers has allowed surgeons to fully detail the anterolateral ligament (ALL) found in the human knee. Two knee surgeons at University Hospitals Leuven have provided the first full anatomical description of a previously enigmatic ligament in the human knee. The ligament appears to play an important role in patients with […]

Researchers Demonstrate A Single Atom Light Switch

Researchers Develop a Single Atom Light Switch

In a newly published study, researchers from the Vienna University of Technology demonstrate highly efficient switching of optical signals between two optical fibers controlled by a single atom. With just a single atom, light can be switched between two fiber optic cables at the Vienna University of Technology. Such a switch enables quantum phenomena to […]

Astronomers Estimate One in Five Sol-Like Stars Have Planets Conducive to Life

Astronomers Reveal How Common Habitable Planets Are

Based on a statistical analysis of all the Kepler data, astronomers now estimate that one in five stars like our Sun have planets about the size of Earth and a surface temperature conducive to life. Berkeley — NASA’s Kepler space telescope, now crippled and its four-year mission at an end, nevertheless provided enough data to […]

Kepler Data Reveal the Discovery of 833 New Candidate Planets

Kepler Data Reveal New Candidate Planets

The latest analysis of Kepler Space Telescope data has revealed the discovery of 833 new candidate planets; ten of these candidates are less than twice the size of Earth and orbit in their sun’s habitable zone. Scientists from around the world are gathered this week at NASA’s Ames Research Center in Moffett Field, California, for […]

Astrophysicists Show How Universe’s Violent Youth Seeded Cosmos with Iron

How the Violent Youth of the Universe Seeded the Cosmos with Iron

The even distribution of iron throughout the Perseus cluster has allowed astrophysicists to tell the billion-year-old story of how exploding stars and black holes sowed the early cosmos with heavy elements. New evidence that iron is spread evenly between the galaxies in one of the largest galaxy clusters in the universe supports the theory that […]

Breakthrough in Quantum Cryptography Demonstrates “Perfectly Secure” Bit Commitment

Breakthrough Demonstrates Perfectly Secure Bit Commitment

For the first time, researchers have demonstrated perfectly secure bit commitment, sending encrypted data between pairs of sites in Geneva and Singapore. A breakthrough in quantum cryptography demonstrates that information can be encrypted and then decrypted with complete security using the combined power of quantum theory and relativity – allowing the sender to dictate the […]

Rudimentary Form of Life Sidesteps Normal Replication Processes

Rudimentary Form of Life Sidesteps Normal Replication Process

Researchers from the University of Nottingham have shown that in some organisms the genetic switches that control DNA replication are unnecessary and that cells will actually grow faster when the replication origins are not present. A rudimentary form of life that is found in some of the harshest environments on earth is able to sidestep […]

Chandra Views Glowing Gas in the Milky Way, NGC 3576

Chandra Reveals Glowing Gas in the Milky Way NGC 3576

Released to the public for the first time, this Chandra/ESO image shows NGC 3576. A region of glowing gas in the Sagittarius arm of the Milky Way galaxy, NGC 3576 is located about 9,000 light years from Earth. Such nebulas present a tableau of the drama of the evolution of massive stars, from the formation […]

Geoscientists Building Whole-Earth Model to Study Long-Term Climate Evolution

Geoscientists Building Whole Earth Model to Study Long Term Climate Evolution

Geoscientists from Rice University are building a whole-Earth model to study long-term climate evolution, focusing on how carbon moves between Earth’s external and internal systems. A Rice University-based team of geoscientists is going to great lengths — from Earth’s core to its atmosphere — to get to the bottom of a long-standing mystery about the […]

Scientists Develop a New Way to Kill Cancer Cells

Scientists Develop a New Way to Kill Cancer Cells

By targeting mitochondria with the anticancer drug cisplatin, chemists have developed a new way to kill cancer cells that have shown resistance to cisplatin. Cisplatin is a chemotherapy drug given to more than half of all cancer patients. The drug kills cells very effectively by damaging nuclear DNA, but if tumors become resistant to cisplatin […]

Smith Cloud Heading Toward the Milky Way at More Than 150 Miles Per Second

Magnetic Field Will Protect Giant Gas Cloud during Collision with Milky Way

Using the National Science Foundation’s Karl G. Jansky Very Large Array and Robert C. Byrd Green Bank Telescope, astronomers discovered a magnetic field deep in the Smith Cloud, which is hurtling toward the Milky Way at more than 150 miles per second and is predicted to impact in approximately 30 million years, that may help […]

New Evidence Supports “Inside-Out” Theory of Galaxy Evolution

Study Shows Galaxies Grow from Inside Out

Using data from NASA’s WISE and GALEX missions, astronomers have gathered new evidence for the “inside-out” theory of galaxy growth, showing that bursts of star formation in central regions were followed one to two billion years later by star birth in the outer fringes. Watching a tree grow might be more frustrating than waiting for […]

Uniform Heavy Element Distribution Points to Early Cosmic ‘Seeding’

Suzaku Study Shows Heavy Elements Formed Early in Cosmic History and Spread Throughout the Universe

Using Suzaku’s X-ray telescopes to make 84 observations of the Perseus Cluster, researchers discovered that most of the universe’s heavy elements, including the iron central to life itself, were already widely dispersed throughout the universe when the cluster began to form, suggesting supernova explosions and active black holes played a lead role in this distribution. […]
