Predicting landslide boundaries two weeks before they happen

Wed, 08/15/2018 - 7:29am
Researchers have developed a software tool that uses applied mathematics and big data analytics to predict the boundary of where a landslide will occur, two weeks in advance.

App that will extend your smartphone battery life

Wed, 08/15/2018 - 5:59am
New research has found a novel method to extend the battery life of smartphones for up to an hour each day.

Artificial intelligence platform screens for acute neurological illnesses

Mon, 08/13/2018 - 8:33am
An artificial intelligence platform designed to identify a broad range of acute neurological illnesses, such as stroke, hemorrhage, and hydrocephalus, was shown to identify disease in CT scans in 1.2 seconds, faster than human diagnosis.

Toward a universal quantum computer

Mon, 08/13/2018 - 5:27am
Researchers have demonstrated holonomic quantum gates under zero-magnetic field at room temperature, which will enable the realization of fast and fault-tolerant universal quantum computers.

Popular encryption software: Researchers help close security hole

Thu, 08/09/2018 - 8:24am
Cybersecurity researchers have helped close a security vulnerability that could have allowed hackers to steal encryption keys from a popular security package by briefly listening in on unintended 'side channel' signals from smartphones.

Holding law enforcement accountable for electronic surveillance

Wed, 08/08/2018 - 4:54am
A new cryptographic system is aimed at improving government accountability for surveillance while still maintaining enough confidentiality for police to do their jobs. AUDIT involves a public ledger in which officials share information about data requests through so-called 'cryptographic commitments.' If the courts decide to release the data they requested, the public can be assured that the correct documents were released in full; if they decide not to, then that refusal itself is made known.

How a computer learns to dribble: Practice, practice, practice

Tue, 08/07/2018 - 6:49am
Basketball players need lots of practice before they master the dribble, and it turns out that's true for computer-animated players as well. By using deep reinforcement learning, players in video basketball games can glean insights from motion capture data to sharpen their dribbling skills.

Smart wristband with link to smartphones could monitor health, environmental exposures

Mon, 08/06/2018 - 11:52am
Engineers have created a smart wristband with a wireless connection to smartphones that will enable a new wave of personal health and environmental monitoring devices. Their technology could be added to watches and other wearable devices that monitor heart rates and physical activity.

A system to synthesize realistic sounds for computer animation

Mon, 08/06/2018 - 10:00am
Sounds accompanying computer-animated content are usually created with recordings. Now, a new system synthesizes synchronized sound at the push of a button.

A kernel of promise in popcorn-powered robots

Thu, 08/02/2018 - 10:08am
Researchers have discovered how to power simple robots with a novel substance that, when heated, can expand more than 10 times in size, change its viscosity by a factor of 10 and transition from regular to highly irregular granules with surprising force. You can also eat it with a little butter and salt.

New tool helps users decide which countries their Internet traffic transits

Thu, 08/02/2018 - 10:07am
The Internet gives people worldwide access to applications and services, but in many cases, Internet traffic passes through a few dominant countries, according to new research.

Broadband internet causes sleep deprivation, a new study finds

Thu, 08/02/2018 - 7:23am
Individuals with DSL access tend to sleep 25 minutes less than their counterparts without DSL Internet. They are significantly less likely to sleep between 7 and 9 hours, the amount recommended by the scientific community, and are less likely to be satisfied with their sleep, researchers find. The effect is largely driven by individuals that face time constraints in the morning and by the use of electronic devices in the evening (not by their use throughout the day)

Computer simulations predict the spread of HIV

Wed, 08/01/2018 - 3:20pm
In a new study, researchers show that computer simulations can accurately predict the transmission of HIV across populations, which could aid in preventing the disease.

Microscale superlubricity could pave way for future improved electromechanical devices

Wed, 08/01/2018 - 8:53am
A new study finds that robust superlubricity can be achieved using graphite and hexagonal boron nitride, which exhibit ultra-low friction and wear. This is an important milestone for future technological applications in the space, automotive, electronics and medical industries.

First-of-its-kind material for the quantum age

Wed, 08/01/2018 - 8:50am
A physicist has discovered a new material that has the potential to become a building block in the new era of quantum materials, those that are composed of microscopically condensed matter and expected to change our development of technology.

Tech takes on cigarette smoking

Wed, 08/01/2018 - 5:40am
Researchers are using wearable sensor technology to develop an automatic alert system to help people quit smoking.

Patients opt for 3D simulation for breast augmentation -- but it doesn't improve outcomes

Tue, 07/31/2018 - 12:13pm
Three-dimensional image simulation is popular among women planning breast augmentation surgery. But while this evolving technology may enhance communication, it doesn't improve patient satisfaction with the results of the procedure.

Artificial intelligence system designs drugs from scratch

Tue, 07/31/2018 - 12:13pm
An artificial-intelligence approach can teach itself to design new drug molecules from scratch and has the potential to dramatically accelerate the design of new drug candidates.

Trapping light that doesn't bounce off track for faster electronics

Mon, 07/30/2018 - 11:54am
A new protective metamaterial 'cladding' prevents light from leaking out of the very curvy pathways it would travel in a computer chip.

Key weakness in modern computer vision systems identified

Mon, 07/30/2018 - 10:29am
In a finding that could point the way toward better computer vision systems, researchers show why computers are so bad at seeing when one thing is not like another.
