The amazing electrical properties of graphene have inspired the creation of a perspex material with remarkable sound-channelling characteristics... 
Absurdly powerful personal computers and smartphones could hit the shelves with 15 years thanks to the invention of a single-atom transistor.
Scientists have found a way to stabilize and regulate the orbit of electrons in an atom, after drawing inspiration from the orbit of asteroids around Jupiter.
In 1913 Danish physicist Neils Bohr’s eponymous Model postulated atoms were formed of electrons orbiting a nucleus, much like planets around the sun – only using electrostatic attraction rather than gravity.
Electrons have since been shown to be more akin to waves surrounding the nucleus, but teams in Austria and the US have shown they can be made to perform in the same way as planetary systems, and the technique can be used to change the overall size of the atom. 
A star shooting matter in a jet stretching over 400 trillion km has been found in the Large Magellanic Cloud, a nearby galaxy to Earth.The star jet covers about 10 times the distance between our Solar System's Sun and nearest neighbouring star proxima Centauri, and is more than 70,000 times the distance between Pluto and the Sun. A discovery that aging nerve fibres can be rejuvenated by young cells may have important implications for treating multiple sclerosis (MS), scientists said. 
Atom-sized wires could lead to extremely small electronics and quantum computers. 
NASA scientists will be tracking asteroid 2005 YU55 with antennas of the agency's Deep Space Network at Goldstone, Calif., as the space rock safely flies past Earth slightly closer than the moon's orbit on Nov. 
Astronomers at The Australian National University have found evidence for the textile that forms the fabric of the Universe. 
By isolating and repeatedly transporting a single, trapped electron from one point on a wire to another, two independent teams of quantum physicists have completed the first major step towards building a quantum computer.
While still in their infancy, quantum computers have the potential to be highly powerful machines, capable of solving certain complex problems much faster than classical computers.
The findings, described in separate papers today in Nature, show a very high level of control over the most fundamental aspect of electronic circuits, the movement of electrons from one place to another. 
Mitochondrial depletion syndrome accounts for about 11 percent of the cases of children born with common myopathies and a more mild form of the syndrome affecting adults. A new finding by Cornell researchers may lead to a nutrition-based treatment with B vitamins. 
Spanish researchers have designed what they believe to be a new type of magnetic cloak, which shields objects from external magnetic fields, while at the same time preventing any magnetic internal fields from leaking outside, making the cloak undetectable.
In their study, published today, Friday 23 September, in the Institute of Physics and German Physical Society's New Journal of Physics, researchers have proved that such a cloak could be built using practical and available materials and technologies, and used to develop an array of applications. 
It was Albert Einstein, no less, who proposed more than 100 years ago that nothing could travel faster than the speed of light.
f the flu virus doesn't kill you, your own immune system might. Sometimes, it unleashes a potentially lethal overreaction to the invading microbe. A new study reveals that a surprising type of cell controls this self-destructive response, pointing toward a new way to prevent the immune system from running amuck. |
Working at Scientific American , known for its spiffy technical illustrations, I always look for material that can show what an article is trying to tell. 
Researchers at the Salk Institute have discovered a startling feature of early brain development that helps to explain how complex neuron wiring patterns are programmed using just a handful of critical genes. The findings, published February 3 in Cell, may help scientists develop new therapies for neurological disorders, such as amyotrophic lateral sclerosis (ALS), and provide insight into certain cancers.enes. 
AUSTIN, Texas — Astronomers have captured an image of a black hole firing off two enormous “bullets” of ionized gas at nearly a quarter the speed of light. The cosmic explosion produces as much energy in an hour as the sun emits in five years. 
Two unexpected new hadrons containing bottom quarks have been discovered by the Belle Experiment using the High Energy Accelerator Research Organization (KEK)'s B Factory (KEKB), a highly-luminous, electron-positron collider.
These new particles have electric charge and are thought to be "exotic" hadrons -- non-standard hadrons, containing at least four quarks. Previously, a series of new and unexpected exotic hadrons containing charm and anti-charm quarks have been observed. This latest discovery from Belle demonstrates the existence of exotic hadrons containing at least four quarks in a particle system including bottom quarks . 
University of Sussex scientists working with researchers in Brazil have identified the first example of a 'soldier' bee. Scientists discover gene responsible for lung cancer - Xinhua http://t.co/UBCS0o0y... 
NASA's Dawn spacecraft has uncovered new details about the asteroid Vesta, including a massive mountain in the space rock's southern hemisphere that is one of the largest in the solar system. 
So far, the only thing moving faster than light is speculation. But in the wake of last week's baffling neutrino news out of CERN, physicists are crunching numbers to test whether these ghostly particles really can move faster than photons. Physicists at Fermilab are re-examining some old data to help answer the question.
In case you live under a rock and missed it, physicists last week said they had evidence neutrinos were moving between Geneva and Gran Sasso, Italy, faster than the speed of light. About three years of data and 15,000 calculations suggested the neutrinos were arriving in Italy earlier than the time it would take light to travel the same distance. 
Human devices, from light bulbs to iPods, send information using electrons. Human bodies and all other living things, on the other hand, send signals and perform work using ions or protons. 
With a strength 200 times greater than that of steel, graphene is the strongest known material to exist. But now scientists have found that folding graphene nanoribbons into structures they call “grafold” can enable it to bear even greater compressive loads. 
Johns Hopkins researchers have devised a protein "switch" that instructs cancer cells to produce their own anti-cancer medication.
In lab tests, the researchers showed that these switches, working from inside the cells, can activate a powerful cell-killing drug when the device detects a marker linked to cancer. The goal, the scientists said, is to deploy a new type of weapon that causes cancer cells to self-destruct while sparing healthy tissue.
This new cancer-fighting strategy and promising early lab test results were reported this week in the online early edition of Proceedings of the National Academy of Sciences. Although the switches have not yet been tested on human patients, and much more testing must be done, the researchers say they have taken a positive first step toward adding a novel weapon to the difficult task of treating cancer.
