Supercomputing the emergence of material behavior

Thu, 05/17/2018 - 11:25am
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.

Mechanical force controls the speed of protein synthesis

Wed, 05/16/2018 - 1:25pm
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 estimated to use half a percent of the world's electric energy by end of 2018

Wed, 05/16/2018 - 10:12am
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.

New device could increase battery life of electronics by a hundred-fold

Wed, 05/16/2018 - 9:36am
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.

The first wireless flying robotic insect takes off

Tue, 05/15/2018 - 11:25am
Engineers have created RoboFly, the first wireless flying robotic insect. RoboFly is slightly heavier than a toothpick and is powered by a laser beam.

New robot concept uses responsive materials to swim through water

Tue, 05/15/2018 - 11:25am
Engineers have created a soft robot that does not rely on a motor to propel itself through the water.

New approach to global-warming projections could make regional estimates more precise

Tue, 05/15/2018 - 8:35am
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.

Deeper understanding of quantum chaos may be the key to quantum computers

Mon, 05/14/2018 - 9:25am
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.

Waterloo chemists create faster and more efficient way to process information

Fri, 05/11/2018 - 5:11am
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.

Researchers hide information in plain text

Thu, 05/10/2018 - 12:02pm
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 interface based on mutual learning helps tetraplegics in avatar race

Thu, 05/10/2018 - 11:58am
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.

Strain improves performance of atomically thin semiconductor material

Thu, 05/10/2018 - 8:50am
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.

Would video games be better if you could play as yourself? Well, not exactly

Thu, 05/10/2018 - 8:50am
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.

Computer-designed customized regenerative heart valves

Wed, 05/09/2018 - 3:54pm
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.

AI detects patterns of gut microbes for cholera risk

Mon, 05/07/2018 - 12:31pm
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.

Protecting confidentiality in genomic studies

Mon, 05/07/2018 - 8:19am
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.

Visual homing for micro aerial vehicles using scene familiarity

Mon, 05/07/2018 - 6:03am
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.

3D reconstruction of hidden branch structures made by using image analysis and AI tech

Mon, 05/07/2018 - 6:02am
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.

Computing: Design for magnetoelectric device may improve memory

Fri, 05/04/2018 - 9:23am
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.
