For headache, telemedicine may be as effective as in-person

Wed, 06/14/2017 - 21:03
For people with headache, seeing the neurologist by video for treatment may be as effective as an in-person visit, according to a study.

Antibiotic design strategy boosts odds against resistance development

Wed, 06/14/2017 - 18:29
A new rational drug design technique that uses a powerful computer algorithm to identify molecules that target different receptor sites on key cellular proteins could provide a new weapon in the battle against antibiotic resistance, potentially tipping the odds against the bugs.

The future of our cities: Engineers test resilient, intelligent infrastructure

Wed, 06/14/2017 - 18:28
Engineers tested several advanced sensors that can collectively measure strain, temperature, movement and leakage – installed along a 40-foot section of a hazard-resilient pipeline being tested for earthquake fault-rupture performance. The results could have huge consequences for urban planners and municipal leaders.

Online cognitive behavioral therapy for insomnia is effective for military

Wed, 06/14/2017 - 17:43
A new study focused on soldiers at Fort Hood who had chronic insomnia. Some received therapy from clinicians for six weeks and some received online therapy for six weeks. For military personnel, internet-delivered cognitive behavioral therapy appears to be an effective alternative to meeting regularly with a therapist, although it is about half as effective as traditional methods, according to results of a study.

Using light to reach higher precision in cell mechanic research

Wed, 06/14/2017 - 17:04
Scientists use optogenetics and mathematical modelling to identify a central molecule in cell mechanics

Researchers refine yardstick for measuring schools

Wed, 06/14/2017 - 16:10
A new study has developed a novel way of evaluating and improving VAMs. By taking data from Boston schools with admissions lotteries, the scholars have used the random assignment of students to schools to see how similar groups of students fare in different classroom settings.

Robot uses deep learning and big data to write and play its own music

Wed, 06/14/2017 - 16:04
A marimba-playing robot with four arms and eight sticks is writing and playing its own compositions in a lab in the USA. The pieces are generated using artificial intelligence and deep learning.

Energy-efficient cleaning robot

Wed, 06/14/2017 - 13:27
State-of-the-art solar cells are efficient -- but are even more so when they are kept clean. A cleaning robot enables solar panels to deliver at full capacity.

Search for Earth-like planets: Try a statistical approach

Wed, 06/14/2017 - 13:19
A team of astronomers seeks to change the way scientists approach the search for Earth-like planets orbiting stars other than the sun. They favor taking a statistical comparative approach in seeking habitable planets and life beyond the solar system.

Visiting virtual beach improves patient experiences during dental procedures

Wed, 06/14/2017 - 13:18
Imagine walking along a beach on a lovely day. As you turn to continue along the coast path feeling calm and relaxed you suddenly hear your dentist say 'Fine, all done, you can take the headset off now'. For patients at one dental practice in Devon, England, such Virtual Reality encounters are resulting in demonstrably better experiences in the dentist's chair.

Breakthrough paves way for smaller electronic devices

Wed, 06/14/2017 - 13:18
A new way to create extremely thin electrically conducting sheets has been discovered, which could revolutionize the tiny electronic devices that control everything from smart phones to banking and medical technology, say investigators.

Superconducting nanowire memory cell, miniaturized technology

Tue, 06/13/2017 - 20:33
Researchers have developed a new nanoscale memory cell that holds tremendous promise for successful integration with superconducting processors. The new technology provides stable memory at a smaller size than other proposed memory devices.

People who are 'phone snubbed' by others often turn to their own phones, social media for acceptance, study finds

Tue, 06/13/2017 - 19:18
People who are phone snubbed – or “phubbed” – by others are, themselves, often turning to their smartphones and social media to find acceptance, according to new research.

Cognitive-related neural pattern to activate machines

Tue, 06/13/2017 - 16:05
A study has identified a functional brain pattern linked to cognitive behavior able to activate an iPad's touchscreen. Results may be useful in brain-machine interfaces, of particular interest for people with physical difficulties to communicate with the outside world.

Charred flowers and the fossil record

Tue, 06/13/2017 - 16:05
One of the main types of fossil used to understand the first flowering plants (angiosperms) are charred flowers. These charcoals were produced in ancient wildfires, and they provide some evidence for the types of plants that grew millions of years ago. However, when fires burn they not only produce charcoal, but they also destroy it.

Can use of a drone improve response times for out-of-hospital cardiac arrests compared to an ambulance

Tue, 06/13/2017 - 15:17
In a study involving simulated out-of-hospital cardiac arrests, drones carrying an automated external defibrillator arrived in less time than emergency medical services, with a reduction in response time of about 16 minutes, according to a study.

Students print their way to new, powerful supercapacitors

Tue, 06/13/2017 - 14:30
Sustainable chemistry students have tripled the specific capacitance of nitrogen-doped carbons: new materials with potential applications in fast energy storage (e.g. for regenerative breaking or fast charging of cellphones). Their experiments required new pieces of equipment which were designed and produced in the lab using 3D printing.

Chemists perform surgery on nanoparticles

Mon, 06/12/2017 - 19:35
A team of chemists has for the first time conducted site-specific surgery on a nanoparticle. The procedure, which allows for the precise tailoring of nanoparticles, stands to advance the field of nanochemistry by allowing researchers to enhance nanoparticles' functional properties, such as catalytic activity and photoluminescence, increasing their usefulness in a wide variety of fields including health care, electronics and manufacturing.

Learning with light: New system allows optical 'deep learning'
