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 […]

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. […]

Hubble Views Proxima Centauri

New Hubble Image of Proxima Centauri

This newly released Hubble image shows Proxima Centauri, which is located just over four light-years from Earth. Shining brightly in this Hubble image is our closest stellar neighbor: Proxima Centauri. Proxima Centauri lies in the constellation of Centaurus (The Centaur), just over four light-years from Earth. Although it looks bright through the eye of Hubble, […]

A Rare View of a Planetary Construction Site in an Intermediate State of Evolution

A Planetary Construction Site in an Intermediate State of Evolution

Using the Herschel Space Observatory and ALMA, researchers have discovered that the unusual disk around the star HD 21997 appears to contain both primordial gas left over from the formation of the star itself and dust that appears to have been produced in collisions between planetesimals. Planets are formed in disks of gas and dust […]
