"We know that some microbes can breathe arsenic, but what we've found is a microbe doing something new -- building parts of itself out of arsenic," said Felisa Wolfe-Simon, a NASA Astrobiology Research Fellow in residence at the U.S. Geological Su
One of the most respected scientists in the field of physics, Sir Roger Penrose, has found concentric circles in the Big Bang data—analogous to ripples in a pond being formed after a stone is tossed into it. He believes those concentric circles are e
According to Ian Pearson, a British futurist, death will be a thing of the past by 2050. Can brain uploading be achieved within 40 years? Sooner, say some experts. What's needed are super fast computers with huge memory capacity. They see that happe
In theory, these ought to be safer than X-rays because millimetre photons do not have enough energy to break chemical bonds. Last year, however, researchers at Los Alamos National Laboratory in New Mexico suggested that these low energy photons coul
The paper-based e-ink technology uses the electrowetting method, in which an electric field is applied to colored droplets in a display unit to effectively turn on and off pixels in an array. Unlike
The confinement of molecular species in nanoscale environments leads to intriguing dynamic phenomena. Notably, the organization and rotational motions of individual molecules were controlled by carefully designed, fully supramolecular host architectu
Scientists are reporting early success at transforming one kind of specialized cell into another, a feat of biological alchemy that doctors may someday perform inside a patient's body to restore health.
There are two ways to go about testing this, neither of which are practical. One requires the energy of dozens of Large Hadron Colliders. The other could yield a cauldron-full of flaming plutonium.
owever, once the body adjusted its expectations it began to lose weight at the rate of 2 ½ pounds per month for four months with no discomfort at all. I suspect that I have dropped fifteen pounds in all to date. An equal amount would place me at my
As Nissan and GM prepare to ship flagship electric vehicles, Toyota is taking another road.
A new handheld ultrasound device could be the first that can connect directly to cell-phone and Wi-Fi networks.
Yet another approach involves Z-pinch – a type of plasma confinement system that uses an electrical current in the plasma (essentially a cloud of ions) to generate a magnetic field that compresses it. The pinch method, which Sandia calls a dark-horse
Engineers have developed a new type of microchip muscle stimulator implant that will enable people with paraplegia to exercise their paralysed leg muscles. It is the first time that researchers have developed a device of this kind that is small enoug
Two memristors can be used for an analog simulation of a synapse. 200 trillion memristors would be a human level synapse system. Memristors can go 1-5 nanometers in the form of nanowires. Hundreds of trillions of memristors would be compact.
Future cars may eat their own exhaust, converting heat from their emissions into electricity. The conversion can improve fuel economy by reducing an engine’s workload.

the Vatican clarified Pope Benedict XVI's stance on condoms Tuesday, saying that the Holy Father believes condoms are an acceptable form of disease prevention for everyone, including men, women, and transsexuals!
“In the future, bio-LED could be used to make roadside trees luminescent at night. This will save energy and absorb CO2 as the bio-LED luminescence will cause the chloroplast to conduct photosynthesis,” said Dr. Yen-Hsun Su in an interview withChemis
The idea that you can "heal" a patient by chemically lobotomizing them is, of course, entirely consistent with the core mythology of modern medicine: If something's wrong, you should poison it, burn it, irradiate it or cut it out...
An unusual breed of Asian snakes can glide long distances in the air, and the Department of DefeMost animals that glide do so with fixed wings or a wing-like part. But not the "flying snakes" of Southeast Asia, India and southern China - at least fiv
For pristine graphene, Sun started with a thin film of poly (methyl methacrylate) (PMMA) – better known as Plexiglass – spun onto a copper substrate that acted as a catalyst. Under heat and low pressure, hydrogen and argon gas was flowed over the PMM
Like the superhydrophobic coating developed by a University of Pittsburgh-led team that mimics the rutted surface of lotus leaves to reduce the surface area to which water can adhere, the Harvard team got their inspiration from natural models. Althou
Scientists claimed a breakthrough Thursday in solving one of the biggest riddles of physics, successfully trapping the first "anti-atom" in a quest to understand what happened to all the antimatter that has vanished since the Big Bang.
EPFL says that accessing one of these nanowires would be like reading an entire VHS tape in less than a second, and the plan is for millions or even billions of these wires to be embedded on one chip. Perhaps you start to get the idea of just how spe
"We found that the transplanted stem cells are permanently altered and reduce the aging of the transplanted muscle, maintaining strength and mass," said Olwin.
ortable devices with painless laser beams could soon replace X-rays as a non-invasive way to diagnose disease. Researchers say that the technique could become widely available in about five years.
The motor's rotor is a long, coal-derived molecule called anthracene, which spins around an axle composed of two ethynyl units. Each end of this axle is connected to an electrode, and a third electrode – called the gate – is located slightly below t
Researchers hope handheld mobile devices will be able to one day read these digital strips of rainbow-colored barcodes -- much like supermarket scanners -- to identify different species by testing tissue samples on site and comparing them with...
A virulent rabies-influenza viral hybrid could lead to masses of infected victims turning into veritable zombies. The hapless former humans would exhibit all the classic features of the horror movies: the would become lumbering, mindless monsters wit
A dramatic breakthrough seems to have been achieved greatly increasing the range and speed of electric vehicles. A revolutionary battery provides enough juice to power a vehicle at a speed of 55mph for 375 miles. That would enable a motorist to take
