Researchers from the U.S. Department of Energy's (DOE) SLAC National Accelerator Laboratory have clocked the fastest-possible electrical switching in magnetite, a naturally magnetic mineral. Their results could drive innovations in the tiny transistors that control the flow of electricity across silicon chips, enabling faster, more powerful computing devices.
Many drugs such as agents for cancer or autoimmune diseases have nasty side effects because while they kill disease-causing cells, they also affect healthy cells. Now a new study has demonstrated a technique for developing more targeted drugs, by using molecular "robots" to hone in on more specific populations of cells.
Mathematicians at UC Irvine in California have designed parameters to measure how to best prevent both one-on-one killings and mass shootings in the United States.
The phenomenon of false memory has been well-documented: In many court cases, defendants have been found guilty based on testimony from witnesses and victims who were sure of their recollections, but DNA evidence later overturned the conviction.
NASA scientists and an international team of researchers have found tropical ecosystems can generate significant carbon dioxide when temperatures rise, unlike ecosystems in other parts of the world.
In a twist on "survival of the fittest," researchers have discovered that evolution is driven not by a single beneficial mutation but rather by a group of mutations, including ones called "genetic hitchhikers" that are simply along for the ride.
No computer works as efficiently as the human brain – so much so that building an artificial brain is the goal of many scientists.
Purple bacteria contain pigments that allow them to use sunlight as their source of energy, hence their color. Small as they are, these microbes can teach us a lot about life on Earth, because they have been around longer than most other organisms on the planet.
A new milestone by engineers at the University of California, Berkeley, can help robots become more touchy-feely, literally.
Ever been looking up the incline of a steep hill and wished you could swap your pedal bike for an electric one…just for a few minutes? Me too. That’s why I was thrilled to learn about Rubbee, a portable high-efficiency electric friction drive that can take any bike from analog to high-tech in seconds flat.
Conventional scientific wisdom has it that plants and other creatures have only lived on land for about 500 million years, and that landscapes of the early Earth were as barren as Mars.
Most big data centers, the global backbone of the Internet, could slash their greenhouse gas emissions by 88 percent by switching to efficient, off-the-shelf equipment and improving energy management, according to new research.
By monitoring artists as they sketch human faces, stroke by stroke, scientists at Disney Research, Pittsburgh, have built computer models that learn each artist's drawing style, how they use strokes and how they select features to highlight as they interpret a face into a portrait.
Puffs of compressed air create sensations that can be associated by the user with textured surfaces or force feedback.
Concentric hexagons of graphene grown in a furnace at Rice University represent the first time anyone has synthesized graphene nanoribbons on metal from the bottom up — atom by atom.
A new low-cost, high-resolution tool is primed to revolutionize how nanotechnology is produced from the desktop, according to a new study by Northwestern University researchers.
Nanosize structure is a thousand times thinner than an ordinary sheet of paper. A highly desirable solution that can change the dynamics of solar cell design.
One more step for our robot overloads: TrackingPoint's new gun technology will create a "Super Gun."
It's widely thought that the Earth arose from violent origins: Some 4.5 billion years ago, a maelstrom of gas and dust circled in a massive disc around the sun, gathering in rocky clumps to form asteroids. These asteroids, gaining momentum, whirled around a fledgling solar system, repeatedly smashing into each other to create larger bodies of rubble — the largest of which eventually cooled to form the planets.
In the near future, people affected by health issues as varied as Alzheimer, diabetes, hearing loss, heart failure or even missing limbs could all have something in common: a smart, efficient, in-body or on-body device that makes their daily life easier and more enjoyable.
