Interstellar Molecules May Be Silicon-Capped Hydrocarbons

Mysterious Molecules in Space May Be Silicon Capped Hydrocarbons

New research from the Harvard-Smithsonian Center for Astrophysics suggests that interstellar molecules may be silicon-capped hydrocarbons like SiC3H, SiC4H and SiC5H. Over the vast, empty reaches of interstellar space, countless small molecules tumble quietly though the cold vacuum. Forged in the fusion furnaces of ancient stars and ejected into space when those stars exploded, these […]

Irregularly Shaped Boulder Rolls Down Martian Hill, Lands Upright

New Mars Image Shows Rolling Boulder

A newly released image from the HiRISE camera on NASA’s Mars Reconnaissance Orbiter shows an irregularly shaped boulder that apparently rolled down a hill on Mars and stopped in an upright position. A track about one-third of a mile (500 meters) long on Mars shows where an irregularly shaped boulder careened downhill to its current […]

Lambda Virus Architecture Finally Rendered

Researchers Produce a Depiction of the DNA Protein Complexes the Lambda Virus

After more than 50 years of research, biologists now have a picture of the molecular machines that allow the lambda virus to insert or remove DNA from the cells that it infects. Providence, Rhode Island (Brown University) — For half a century biologists have studied the way that the lambda virus parks DNA in the […]

New Measurements May Help Identify Antiquark’s Role in Proton’s Spin

Particle Physicists Measure the Spin Contribution of Antiquark

Using the STAR detector at Brookhaven National Laboratory, scientists have identified a new method sensitive to the antiquark spin, which can shed light on where these quarks and antiquarks come from. This fundamental question has been a longstanding mystery in particle physics, although it was once thought that the answer would be fairly straightforward: The […]

Neurobiologists Examine Insular Cortex, Could Play an Important Role in Autism

New Research Could Lead to Therapeutic Strategies for Autism

Scientists from Harvard University and the Max-Planck Institute unravel a neural circuit that could play an important role in autism. The insular cortex is an integral “hub”, combining sensory, emotional and cognitive content. Not surprisingly, alterations in insular structure and function have been reported in many psychiatric disorders, such as anxiety disorders, depression, addiction and […]

Researchers Grow Single-Walled Carbon Nanotubes with Identical Electronic Properties

Scientists Grow Custom Made Nanotubes

Using custom-made organic precursor molecules, researchers have succeeded for the first time in growing single-walled carbon nanotubes with identical electronic properties. In future, it will be possible to specifically equip carbon nanotubes with properties which they need for electronic applications, for example. Researchers at Empa in Dübendorf/Switzerland and the Max Planck Institute for Solid State […]

Materials Scientists Turn Metal Into Glass

Engineers Form Monatomic Metallic Glasses

In a newly published study, University of Pittsburgh researchers report an experimental approach to the formation of monatomic metallic glasses through ultrafast liquid quenching. Materials scientists have long sought to form glass from pure, monoatomic metals. Scott X. Mao and colleagues did it. Their paper, “Formation of Monoatomic Metallic Glasses Through Ultrafast Liquid Quenching,” was […]

A*STAR Researchers Develop High-Capacity Method to Purify Monoclonal Antibodies

Magnetic Nanoparticles Break the Capacity Barrier for Antibody Purification

Researchers from A*STAR have developed a high-capacity method to purify monoclonal antibodies that uses magnetic nanoparticles. Monoclonal antibodies represent the largest and fastest-growing segment of international biopharma. While these therapeutic agents are a boon for global healthcare, productivity constraints pose a serious challenge for manufacturers seeking to make sufficient amounts for therapeutic applications. Now, A*STAR […]

Cassini Tracks Clouds Developing Over Ligeia Mare on Titan

Cassini Tracks Clouds Developing Over a Sea on Titan

A newly released animated image from NASA’s Cassini spacecraft shows methane clouds moving above the large methane sea known as Ligeia Mare on Saturn’s moon Titan. NASA’s Cassini spacecraft recently captured images of clouds moving across the northern hydrocarbon seas of Saturn’s moon Titan. This renewed weather activity, considered overdue by researchers, could finally signal […]

NuSTAR Sees Rare Event Near Supermassive Black Hole Markarian 335

NuSTAR Sees Rare Blurring of Black Hole Light

NuSTAR observations reveal X-ray light streaming from regions near supermassive black hole Markarian 335. NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) has captured an extreme and rare event in the regions immediately surrounding a supermassive black hole. A compact source of X-rays that sits near the black hole, called the corona, has moved closer to the […]
