Study Describes a Biological Transistor for Computing Within Living Cells

Biological Transistor Enables Computing Within Living Cells

In a newly published study, Stanford researchers describe a biological transistor that is made from genetic material (DNA and RNA) in place of gears or electrons. When Charles Babbage prototyped the first computing machine in the 19th century, he imagined using mechanical gears and latches to control information. ENIAC, the first modern computer developed in […]

Scientists Successfully Map Telomerase, Discover Risk of Various Cancers

Researchers Successfully Map Telomerase

For the first time, researchers have successfully mapped telomerase, finding that differences in the telomeric gene are associated both with the risk of various cancers and with the length of the telomeres. In collaboration with an international research team, University of Copenhagen researchers have for the first time mapped telomerase, an enzyme which has a […]

Revolutionary Laser System Composed of Massive Arrays of Thousands of Fiber Lasers

Physicists Propose a Revolutionary Laser System Inspired by Telecommunications Technology

By replacing the single monolithic rod amplifier that typically equips lasers with a network of fiber amplifiers and telecommunication components, scientists aim to harness the efficiency, controllability, and high average power capability of fiber lasers to produce high energy, high repetition rate pulse sources. An international team of physicists has proposed a revolutionary laser system, […]

New Cooling Technique May Be a Stepping Stone to Quantum Computing

Cooling Technique May Be a Stepping Stone to Quantum Computing

By immersing charged barium chloride molecules in an ultracold cloud of calcium atoms, UCLA physicists have pioneered a new cooling technique that may be a stepping stone to quantum computing. The next generation of computers promises far greater power and faster processing speeds than today’s silicon-based based machines. These “quantum computers” — so called because […]

Cassini Data Suggests Saturn’s Moons and Rings Are More Than 4 Billion Years Old

New Data Suggests That the Moons and Rings of Saturn Are More Than 4 Billion Years Old

Data from NASA’s Cassini spacecraft suggests that the moons and rings of Saturn are more than 4 billion years old. A new analysis of data from NASA’s Cassini spacecraft suggests that Saturn’s moons and rings are gently worn vintage goods from around the time of our solar system’s birth. Though they are tinted on the […]

Scientists Produce a Ceramic Paper Consisting of Conductive Nanofibers

Nanostructure Renders a Wafer Thin Paper

Scientists have developed an electrically conductive paper-like material from a vanadium pentoxide ceramic that is as hard as copper, yet flexible enough to be rolled up or folded. Scientists in Stuttgart are currently doing things to a ceramic, which would normally result in a pile of shards. They were the first to produce a paper-like […]

Physicists Measure Magnetic Moment of Single Particles of Matter and Antimatter

Physicists Measure Magnetic Charge of Single Particles of Matter and Antimatter

A research team led by Harvard University physicists has measured the magnetic moment of single particles of matter and antimatter with unprecedented precision. As described in a March 25 paper in Physical Review Letters, the team — led by Gerald Gabrielse, the George Vasmer Leverett Professor of Physics, and including postdoctoral fellows Stephan Ettenauer and […]

Herschel Data Reveals Clues About High-Mass Star Formation

How Baby Stars Grow to Great Mass

In a new study, scientists use Herschel data to view a giant cloud of gas and dust called Westerhout 3 and to study the early stages of high-mass star formation, finding that baby stars may grow to great mass if they happen to be born within a corral of older stars. Newswise — Stars ten […]

Researchers Develop an Ultra-Thin Invisibility Cloak

Researchers Develop an Ultrathin Invisibility Cloak

In a newly published study, scientists from the University of Texas at Austin detail a “metascreen” cloak that is ultra-thin and can hide three-dimensional objects from microwaves in their natural environment. Austin, Texas — Until now, the invisibility cloaks put forward by scientists have been bulky devices — an obvious flaw for those interested in […]

Human Cells Enhance Synaptic Plasticity and Learning in Adult Mice

Human Brain Cells Make Mice Smarter

In a new study, researchers transplanted human glial progenitor cells (GPCs) into mice, finding that the transplanted mice were more rapid learners and acquired new associations and performed a variety of tasks significantly faster than mice without the human glial cells. Glial cells – a family of cells found in the human central nervous system […]

The Blue Stars of Cluster NGC 2547

The Blue Stars of Cluster NGC 2547

ESO’s La Silla Observatory in Chile captured this new image of blue stars in the open star cluster NGC 2547. This pretty sprinkling of bright blue stars is the cluster NGC 2547, a group of recently formed stars in the southern constellation of Vela (The Sail). This image was taken using the Wide Field Imager […]

NASA’s MAVEN Spacecraft to Study Martian Atmosphere

NASAs MAVEN Spacecraft Prepares for Launch

Scheduled to launch in late 2013, NASA’s MAVEN spacecraft will study the Martian upper atmosphere in detail, gathering information about relevant processes so scientists can infer how the planet’s atmosphere evolved. When you navigate with a compass you can orient yourself thanks to Earth’s global magnetic field. But on Mars, if you were to walk […]

Researchers Reprogram Nerve Cells Directly in the Brain

Researchers Reprogram Other Cells to Become Nerve Cells Directly in the Brain

Using genes inserted into two types of human cells, fibroblasts and glia cells, researchers showed that it is possible to reprogram other cells to become nerve cells directly in the brain. The field of cell therapy, which aims to form new cells in the body in order to cure disease, has taken another important step […]

Neurons That Control Hunger Could Help Control Autoimmune Diseases

Neurons That Control Hunger Could Help Control Autoimmune Diseases

Researchers at the Yale School of Medicine have discovered that hunger-spiking neurons could help control autoimmune diseases, unmasking a previously unsuspected role of hypothalamic feeding circuits in the regulation of adaptive immune response. Neurons that control hunger in the central nervous system also regulate immune cell functions, implicating eating behavior as a defense against infections […]

New Research Shows That Ephemeral Vacuum Particles Induce Speed-of-Light Fluctuations

New Research Shows That the Speed of Light May Not Be Fixed

Two newly published studies challenge established wisdom about the nature of vacuum, finding that ephemeral vacuum particles induce speed-of-light fluctuations. In one paper, Marcel Urban from the University of Paris-Sud, located in Orsay, France and his colleagues identified a quantum level mechanism for interpreting vacuum as being filled with pairs of virtual particles with fluctuating […]
