Chemists have designed the first artificial protein assembly (C98RhuA) whose conformational dynamics can be chemically and mechanically toggled. The Maverick GPU-based supercomputer at the Texas Advanced Computing Center simulated the system through an allocation on NSF-funded XSEDE, the Extreme Science and Engineering Discovery Environment. The research could help create new materials for renewable energy, medicine, water purification, and more.
As cells create proteins, the proteins modulate synthesis speed by exerting a mechanical force on the molecular machine that makes them, according to a team of scientists who used a combination of computational and experimental techniques to understand this force.
Bitcoin's burgeoning electricity demands have attracted almost as much attention as the cryptocurrency's fluctuating value. But estimating exactly how much electricity the Bitcoin network uses remains a challenge. A new methodology helps pinpoint where Bitcoin's electric energy consumption is headed and how soon it might get there.
Among the chief complaints for smartphone, laptop and other battery-operated electronics users is that the battery life is too short and -- in some cases -- that the devices generate heat. Now, a group of physicists has developed a device material that can address both issues. The team has applied for a patent for a magnetic material that employs a unique structure -- a 'honeycomb' lattice that exhibits distinctive electronic properties.
Engineers have created RoboFly, the first wireless flying robotic insect. RoboFly is slightly heavier than a toothpick and is powered by a laser beam.
Engineers have created a soft robot that does not rely on a motor to propel itself through the water.
A new method for projecting how the temperature will respond to human impacts supports the outlook for substantial global warming throughout this century - but also indicates that, in many regions, warming patterns are likely to vary significantly from those estimated by widely used computer models.
New research gives insight into a recent experiment that was able to manipulate an unprecedented number of atoms through a quantum simulator. This new theory could provide another step on the path to creating the elusive quantum computers.
Chemists have found a much faster and more efficient way to store and process information by expanding the limitations of how the flow of electricity can be used and managed.
Computer scientists have invented FontCode, a way to embed hidden information in ordinary text by imperceptibly changing the shapes of fonts in text. The hidden information persists even when documents or images with perturbed texts are printed or converted to another file type. Method could prevent document tampering, protect copyrights, as well as embed QR codes and other metadata without altering the look or layout of a document.
Brain-computer interfaces (BCIs) are seen as a potential means by which severely physically impaired individuals can regain control of their environment, but establishing such an interface is not trivial. A new study suggests the most dramatic improvements in computer-augmented performance are likely to occur when both human and machine are allowed to learn.
Materials scientists show conclusively for the first time that the properties of atomically thin materials can be mechanically manipulated to enhance their performance. The finding could lead to faster computer processors and more efficient optical sensors.
A new study shows no gender difference or negative effect on a video game player's performance or subjective involvement based on whether a photorealistic avatar looked like them or like their friend.
Cardiovascular tissue engineering aims to treat heart disease with prostheses that grow and regenerate. Now, researchers have successfully implanted regenerative heart valves, designed with the aid of computer simulations, into sheep for the first time.
Researchers have used artificial intelligence to spot patterns within the communities of bacteria living in the human gut. These patterns could indicate who among the approximately one billion people around the globe at risk of cholera infection will get sick with the diarrheal disease.
Researchers have developed a system for protecting the privacy of people who contribute genomic data to biomedical studies. The cryptographic system could enable 'crowdsourced' genomics studies involving as many as a million genomes.
Researchers have discovered that a navigation algorithm is able to allow MAVs to find their way back to an earlier visited location fairly quickly and efficiently, allowing it to function more similar to a flying insect.
Scientists have succeeded in reconstruction of plant branch structures, including the branch structures under leaves, by using image analysis and artificial intelligence technology, a world first.
Conventional memory devices use transistors and rely on electric fields to store and read out information. An alternative approach uses magnetic fields, and a promising version relies on the magnetoelectric effect which allows an electric field to switch the magnetic properties of the devices. Existing devices, however, tend to require large magnetic and electric fields. One potential solution is a new switching element made from chromia.
Scientists have discovered a method to encode information using magnets that are just a few layers of atoms in thickness. This breakthrough may revolutionize both cloud computing technologies and consumer electronics by enabling data storage at a greater density and improved energy efficiency.
