'Neuroprosthesis' restores words to man with paralysis

Posted: 14 Jul 2021 02:41 PM PDT

Researchers have successfully developed a 'speech neuroprosthesis' that has enabled a man with severe paralysis to communicate in sentences, translating signals from his brain to the vocal tract directly into words that appear as text on a screen.

Trust me, I'm a chatbot

Posted: 14 Jul 2021 10:19 AM PDT

More and more companies are using chatbots in customer services. Due to advances in artificial intelligence and natural language processing, chatbots are often indistinguishable from humans when it comes to communication. But should companies tell customers they are communicating with machines and not with humans? Researchers investigated. Their research found that consumers tend to react negatively when they learn that the person they are talking to is, in fact, a chatbot.

Detecting wildlife illness and death with new early alert system

A new early detection surveillance system for wildlife helps identify unusual patterns of illness and death in near real-time by tapping into data from wildlife rehabilitation organizations across California, explains a new study.

Small molecule plays outsize role in controlling nanoparticle

Posted: 14 Jul 2021 10:18 AM PDT

A breakthrough imaging technique has enabled researchers to gain new insights into how tiny ligands bind to the surface of nanoparticles and change a particle's shape.

The hidden culprit killing lithium-metal batteries from the inside

Posted: 14 Jul 2021 10:18 AM PDT

The first nanoscale images ever taken inside intact, lithium-metal coin batteries (also called button cells or watch batteries) challenge prevailing theories and could help make future high-performance batteries, such as for electric vehicles, safer, more powerful and longer lasting.

How to make biomedical research data able to interact?

Posted: 14 Jul 2021 08:06 AM PDT

Interoperability describes the ability of different systems to communicate. Scientists have now developed the strategy for a national infrastructure adopted by Swiss university hospitals and academic institutions. With its pragmatic approach, this strategy is based on the development of a common semantic framework that does not aim to replace existing standards, but to use them in a synergistic and flexible way according to the needs of the research and the partners involved.

New mechanism of superconductivity discovered in graphene

New mechanism of superconductivity discovered in graphene. Placing a 2D Bose-Einstein condensate in the vicinity of a graphene layer confers superconductivity to the material.

New evidence of an anomalous phase of matter brings energy-efficient technologies closer

Posted: 14 Jul 2021 08:05 AM PDT

Researchers have found evidence for an anomalous phase of matter that was predicted to exist in the 1960s. Harnessing its properties could pave the way to new technologies able to share information without energy losses.

Personalized 3D printed knee implant could help thousands of arthritis sufferers

Posted: 14 Jul 2021 08:05 AM PDT

Pioneering 'printed metal' procedure to create bespoke treatment for early knee osteoarthritis set to be trialed in the UK following MHRA approval.

Swarm of autonomous tiny drones can localize gas leaks

Posted: 14 Jul 2021 08:05 AM PDT

When there is a gas leak in a large building or at an industrial site, human firefighters currently need to go in with gas sensing instruments. Finding the gas leak may take considerable time, while they are risking their lives. Researchers have now developed the first swarm of tiny - and hence very safe - drones that can autonomously detect and localize gas sources in cluttered indoor environments.

Chemistry discovery could remove micropollutants from environment

Posted: 14 Jul 2021 08:05 AM PDT

New research identified a new chemistry approach that could remove micropollutants from the environment.

Idea sharing increases online learner engagement

Posted: 14 Jul 2021 08:05 AM PDT

Online learning engagement can be increased by nearly one-third by simply prompting students to share course ideas rather than personal details in the form of icebreakers and social introductions.

Hydrogel composite developed to help protective gear rapidly degrade toxic nerve agents

Posted: 14 Jul 2021 08:05 AM PDT

Scientists have developed a hydrogel integrated with zirconium-based robust metal-organic frameworks (MOFs) that rapidly degrades organophosphate-based nerve agents used in chemical warfare. Unlike existing powdered MOF adsorbents, this hydrogel composite does not require added water and may be easily scaled up for use in protective masks or clothing.

Opening the gate to the next generation of information processing

Posted: 14 Jul 2021 08:05 AM PDT

Scientists have devised a means of achieving improved information processing with a new technology for effective gate operation. This technology has applications in classical electronics as well as quantum computing, communications and sensing.

Study puts charge into drive for sustainable lithium production

Posted: 14 Jul 2021 08:05 AM PDT

A new study has yielded critical fresh insights into the lithium production process and how it relates to long-term environmental sustainability, particularly in the area of transportation with batteries and electric vehicles.

Business use of avatars

Posted: 14 Jul 2021 08:05 AM PDT

Tamarind shells converted into an energy source for vehicles

Posted: 14 Jul 2021 08:04 AM PDT

A team of scientists has found a way to process tamarind shells which are rich in carbon, converting the waste material into carbon nanosheets, which are a key component of supercapacitors - energy storage devices that are used in automobiles, buses, electric vehicles, trains, and elevators.

New system for tracking macaws emphasizes species' conservation needs

Posted: 14 Jul 2021 08:04 AM PDT

New data on macaw movements has the potential to greatly improve conservation strategies for the scarlet macaw, as well as similar species of large parrots.

Liquid metal sensors and AI could help prosthetic hands to 'feel'

Posted: 14 Jul 2021 08:03 AM PDT

Prosthetics currently lack the sensation of 'touch.' To enable a more natural feeling prosthetic hand interface, researchers are the first to incorporate stretchable tactile sensors using liquid metal and machine learning. This hierarchical multi-finger tactile sensation integration could provide a higher level of intelligence for artificial hands by improving control, providing haptic feedback and reconnecting amputees to a previously severed sense of touch.
