Phys.org / Strained liquid crystals steer soliton 'bullets' along two diagonal paths
In physics, some waves behave in a surprising way: instead of spreading out and fading, they hold their shape as they travel at constant speeds. These unusual waves, called solitons, have interested scientists since they ...
Phys.org / Graphene 'leaf tattoo' sensor tracks plant hydration in real time
Is your houseplant thirsty? Are crops getting enough water? Is a forest at high risk of wildfire? Leaf health can answer all these questions, and researchers at The University of Texas at Austin have developed new technology ...
Dialog / Three-in-one diode integrates sensing, memory and processing for smart cameras
Think about how easily you recognize a friend in a dimly lit room. Your eyes capture light, while your brain filters out background noise, retrieves stored visual information, and processes the image to make a match. It all ...
Phys.org / Cyclic catalysts use sunlight and air to regenerate during pharma ingredient synthesis
In chemical processes for producing pharmaceuticals, catalysts are a core technology that determines production speed and cost. However, until now, there has been a trade-off between "precise but disposable catalysts" and ...
Phys.org / Sacrifice before the cataclysm: The aromas of Pompeii's household altars
The destruction of Pompeii preserved ash residues on the household altars of its inhabitants. An international research team has scientifically investigated for the first time what was burned in Roman incense burners from ...
Medical Xpress / Stopping tick spit: What a new saliva control map could mean for Lyme prevention
Ticks are major vectors of infectious diseases, affecting both animals and humans. Their ability to remain attached to a host and feed on their blood over the course of several days derives from their saliva, which prevents ...
Medical Xpress / Algae-derived sugars show anti-inflammatory effects and support skin repair
Chronic wounds affect approximately 2% of the population in developed countries. Existing treatments are expensive and may cause side effects. In his doctoral thesis, Amal D. Premarathna shows that a promising alternative ...
Medical Xpress / Investigational drug delivers mixed results for uncontrolled blood pressure
The investigational drug tonlamarsen—which is designed to lower blood pressure by reducing the production of angiotensinogen, a protein that turns into the hormone that regulates blood pressure—caused a significant and sustained ...
Medical Xpress / Left atrial appendage closure noninferior to blood thinners for lowering stroke risk, death in some patients with AFib
For patients with nonvalvular atrial fibrillation (AFib) who had no contraindications to taking oral anticoagulants, the use of a device to close off the left atrial appendage in the heart—a small pouch where blood can pool ...
Tech Xplore / Photonic chip packaging can withstand extreme environments
Researchers at the National Institute of Standards and Technology (NIST) have developed a new way to package photonic integrated circuits—tiny chips that convey information using light instead of electricity—so they can survive ...
Medical Xpress / Brain wiring model could shorten path to new medicines
A new, more life-like physical model of microscopic nerve fibers called axons could speed up the discovery of medicines for multiple sclerosis and other degenerative brain diseases, suggests a new study led by UCL researchers. ...
Medical Xpress / New compound MF-8 may treat anxiety and memory loss with fewer side effects
Scientists at City University of Hong Kong (CityUHK) have made progress in recent months with the discovery of a novel compound, named MF-8. The compound and its associated pharmaceuticals demonstrate significant potential ...
