| 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. |
| New mathematical solutions to an old problem in astronomy Posted: 30 Aug 2021 09:32 AM PDT The Bernese theoretical astrophysicist Kevin Heng has achieved a rare feat: On paper, he has derived novel solutions to an old mathematical problem needed to calculate light reflections from planets and moons. Now, data can be interpreted in a simple way to understand planetary atmospheres, for example. The new formulae will likely be incorporated into future textbooks. |
| ‘Smart’ shirt keeps tabs on the heart Posted: 30 Aug 2021 09:32 AM PDT 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. |
| AI helps to spot single diseased cells Posted: 30 Aug 2021 08:33 AM PDT Researchers developed a novel artificial intelligence algorithm for clinical applications called 'scArches'. It efficiently compares patients' cells with a reference atlas of cells of healthy individuals. This enables physicians to pinpoint cells in disease and prioritize them for personalized treatment in each patient. |
| 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. |
