Technology breakthrough fuels laptops and phones, recharges scientist's 60-year career

How does a scientist fuel his enthusiasm for chemistry after 60 years? By discovering a new energy source, of course.

Scientists build world's first anti-laser

More than 50 years after the invention of the laser, scientists at Yale University have built the world

New material provides 25 percent greater thermoelectric conversion efficiency

Automobiles, military vehicles, even large-scale power generating facilities may someday operate far more efficiently thanks to a new alloy developed at the U.S. Department of Energy

Next-generation electronic devices: conduction, surface states in topological insulator nanoribbons controlled

In recent years, topological insulators have become one of the hottest topics in physics. These new materials act as both insulators and conductors, with their interior preventing the flow of electrical currents while their edges or surfaces allow the movement of a charge. Perhaps most importantly, the surfaces of topological insulators enable the transport of spin-polarized electrons while preventing the

Revolutionary microchip technology?

Scientists have made the world’s first junctionless transistor even smaller. The transistor is the building block of the microchip.

Successful operation of carbon nanotube-based integrated circuits manufactured on plastic substrates

Scientists have developed a simple and fast process to manufacture high-quality carbon nanotube-based thin film transistors (TFT) on a plastic substrate, enabling them to manufacture the world

Researchers produce world's first programmable nanoprocessor`

Engineers and scientists collaborating at Harvard University and the MITRE Corporation have developed and demonstrated the world

Physicists use natural crystals to develop invisibility cloak

Physicists from the University of Birmingham, with colleagues at Imperial College, London and Technical University of Denmark, have demonstrated an

DNA engine observed in real-time traveling along base pair track

In a complex feat of nanoengineering, a team of scientists at Kyoto University and the University of Oxford have succeeded in creating a programable molecular transport system, the workings of which can be observed in real time. The results, appearing in the latest issue of Nature Nanotechnology, open the door to the development of advanced drug delivery methods and molecular manufacturing systems.

New nanomaterials unlock new electronic and energy technologies

Researchers have discovered a new way of splitting layered materials to give atom-thin nanosheets.This has led to a range of novel two-dimensional

Researchers capture jumping genes

An ambitious hunt by Johns Hopkins scientists for actively "jumping genes" in humans has yielded compelling new evidence that the genome, anything but static, contains numerous pesky mobile elements that may help to explain why people have such a variety of physical traits and disease risks.

Scientists unlock one mystery of tissue regeneration

Researchers at the University of Rochester have now identified a genetic switch that controls oxidative stress in stem cells and thus governs stem cell function.

Quantum quirk: scientists pack atoms together to prevent collisions in atomic clock

In a paradox typical of the quantum world, JILA scientists have eliminated collisions between atoms in an atomic clock by packing the atoms closer together. The surprising discovery, described in the Feb. 3 issue of Science Express, can boost the performance of experimental atomic clocks made of thousands or tens of thousands of neutral atoms trapped by intersecting laser beams.

Human genome's breaking points: genetic sequence of large-scale differences between human genomes

Scientists have identified the genetic sequence of an unprecedented 28,000 structural variants -- large portions of the human genome which differ from one person to another. The work could help find the genetic causes of some diseases and also begins to explain why certain parts of the human genome change more than others.
