Improving strength, stretchiness and adhesion in hydrogels for wound healing

Posted: 30 Aug 2021 01:39 PM PDT

Scientists use the adhesive capabilities of mussels as a model for simultaneously optimizing the strength, stretchiness and adhesion of GelMA hydrogels, a feat not obtained in previous attempts.

Improved water splitting method: A green energy innovation

Posted: 30 Aug 2021 01:39 PM PDT

Hydrogen is a promising clean energy source with great potential to replace greenhouse gas-emitting fossil fuels. While total water (H2O) splitting is the easiest way to obtain hydrogen (H2), this reaction is slow and not yet commercially feasible. Now, scientists have developed a novel electrocatalyst that significantly improves hydrogen production from water splitting in an energy and cost-efficient way.

Reliable oxygenation conceivable with new design for portable concentrators

Posted: 30 Aug 2021 12:29 PM PDT

Anticipating the increased need for better oxygen concentrators as the fight against COVID-19 rages on, researchers have laid a computational framework to design the most optimal concentrator to filter ambient air and produce oxygen that can scale with patient demand.

Turning thermal energy into electricity

Posted: 30 Aug 2021 11:02 AM PDT

With the addition of sensors and enhanced communication tools, providing lightweight, portable power has become even more challenging. New research demonstrated a new approach to turning thermal energy into electricity that could provide compact and efficient power.

‘Smart’ shirt keeps tabs on the heart

Carbon nanotube thread woven into athletic shirts gathered electrocardiogram and heart rate data that matched standard monitors and beat chest-strap monitors. The fibers are flexible and the shirts are machine washable.

'Charging room' system powers lights, phones, laptops without wires

Posted: 30 Aug 2021 09:32 AM PDT

In a move that could one day free the world's countertops from their snarl of charging cords, researchers have developed a system to safely deliver electricity over the air, potentially turning entire buildings into wireless charging zones.

Researchers identify new biomarkers to detect consumption of emerging illicit drug

Posted: 30 Aug 2021 08:33 AM PDT

A team of researchers has come up with a new solution to boost the surveillance of designer drug abuse. The team has identified three new urinary biomarkers that could be used to detect consumption of ADB-BUTINACA, an emerging synthetic cannabinoid which is a type of new psychoactive substance. The innovative approach used to identify the biomarkers can be applied to other existing and new synthetic cannabinoids.

Drug delivery capsule could replace injections for protein drugs

Posted: 30 Aug 2021 08:33 AM PDT

Researchers have developed a capsule that can carry large protein drugs, such as monoclonal antibodies, and inject them directly into the lining of the stomach.

Unease beyond the uncanny valley: How people react to the same faces

Posted: 30 Aug 2021 07:49 AM PDT

If humanoid robots with the same appearance are mass-produced and become commonplace, how will human beings react to them? In a series of six experiments, scientists examined peoples' reactions when presented with images of people with the same face. Their results reveal a new phenomenon they call the clone devaluation effect -- a greater eeriness associated with cloned faces than with different faces.

Bright idea: New LEDs can detect off-food and lethal gases

Posted: 30 Aug 2021 06:22 AM PDT

New LED technology has potential to benefit firefighters, miners, military, plumbers and households.

Synthetic biology enables microbes to build muscle

Posted: 30 Aug 2021 05:17 AM PDT

Would you wear clothing made of muscle fibers? Use them to tie your shoes or even wear them as a belt? It may sound a bit odd, but if those fibers could endure more energy before breaking than cotton, silk, nylon, or even the material used in bullet-proof vests, then why not?

The physics behind a tardigrade's lumbering gait

Posted: 27 Aug 2021 03:41 PM PDT

Animals as small and soft as tardigrades seldom have legs and almost never bother walking. But a new study finds that water bears propel themselves through sediment and soil on eight stubby legs, in a manner resembling that of insects 500,000 times their size.

Nanoscale systems for generating various forms of light

Posted: 27 Aug 2021 03:41 PM PDT

In new findings published in Nature Communications, researchers from Louisiana State University and four collaborating universities have introduced a discovery that changes a paradigm in quantum plasmonics by demonstrating the potential of metallic nanostructures to produce different forms of light.

Can a piece of sticky tape stop computer hackers in their tracks?

Posted: 26 Aug 2021 08:17 AM PDT

Researchers have taken the fight to online hackers with a giant leap towards realizing affordable, accessible quantum communications, a technology that would effectively prevent the decryption of online activity. Everything from private social media messaging to banking could become more secure due to new technology created with a humble piece of adhesive tape.
