With a technique that overcomes cells’ innate social behaviors, researchers have taken an important step in directing skin cells to migrate en masse to close wounds _ “literally making skin crawl,” said principal investigator Daniel Cohen.

An 'AI-based automatic pothole detection system' is designed to be installed on the windshield of a vehicle to detect potholes on the road surface in real-time. Potholes can damage cars and may even lead to life-threatening accidents.

Physicists have created a new way to observe details about the structure and composition of materials that improves upon previous methods. Conventional spectroscopy changes the frequency of light shining on a sample over time to reveal details about them. The new technique, Rabi-oscillation spectroscopy, does not need to explore a wide frequency range so can operate much more quickly. This method could be used to interrogate our best theories of matter in order to form a better understanding of the material universe.

PITTSBURGH, July 26, 2021 - Adolescents who set goals for their future and those with strong parental support are less likely to use e-cigarettes and other tobacco products, according to a study by UPMC Children's Hospital of Pittsburgh and University of Pittsburgh School of Medicine physician-scientists.

The research, published today in the journal Pediatrics, suggests that strategies to prevent youth vaping may be different from what works to dissuade youth from smoking cigarettes.

Oncotarget published "TERT and its binding protein: overexpression of GABPA/B in high grade gliomas" which reported that all GA-binding proteins progress through the glioma grades and have the highest expression levels in secondary glioblastomas.

Thermal-imaging sensors that detect and capture images of the heat signatures of human bodies and other objects have recently sprung into use in thermostats to check facial temperatures in a contactless attempt to screen for COVID-19 at several building entrances. Under these circumstances, the smartphone industry is actively considering the incorporation of such sensors as portable features to create the add-on function of measuring temperature in real time. Additionally, the application of such technology to autonomous vehicles may facilitate safer autonomous driving.

The feeling of a needle piercing skin is familiar to most people, especially recently as COVID-19 vaccinations gain momentum. But what exactly happens when a needle punctures skin? The answer is revealed in a new paper published recently in the Journal of the Mechanics and Physics of Solids.

Even in the absence of bark beetle outbreaks and wildfire, trees in Colorado subalpine forests are dying at increasing rates from warmer and drier summer conditions, found recent University of Colorado Boulder research.

The study, published in the May print issue of the Journal of Ecology, also found that this trend is increasing. In fact, tree mortality in subalpine Colorado forests not affected by fire or bark beetle outbreaks in the last decade has more than tripled since the 1980s.

MEADVILLE, PA - July 22, 2021 - Shark Week is many things. First and foremost, it's a week of shark-themed documentary programming on the Discovery Channel. Now in its 33rd year, it's the longest-running cable event in history. It's the biggest audience that marine biologists and ocean conservationists get, attracting millions of viewers who might otherwise not ever think about sharks at all. It's a stage that has launched careers of shark scientists and inspired many others to pursue jobs as ocean scientists.

New York, NY (July 23, 2021) -- Mount Sinai researchers have developed a therapeutic agent that shows high effectiveness in vitro at disrupting a biological pathway that helps cancer survive, according to a paper published in Cancer Discovery, a journal of the American Association for Cancer Research, in July.

EVANSTON, Ill., --- One of the keys to a long life may lie in your net worth.

In the first wealth and longevity study to incorporate siblings and twin pair data, researchers from Northwestern University analyzed the midlife net worth of adults (mean age 46.7 years) and their mortality rates 24 years later. They discovered those with greater wealth at midlife tended to live longer.

WESTMINSTER, Colorado - July 23, 2021 - Horseweed is a serious threat to both agricultural crops and natural landscapes around the globe. In the U.S., the weed is prolific and able to emerge at any time of the year.

Fall emerging horseweed overwinters as a rosette, while spring emerging horseweed skips the rosette stage and grows upright. In some instances, both rosette and upright plants emerge simultaneously in mid-summer. These unpredictable growth patterns create challenges for growers as they try to develop an appropriate weed management plan.

When can we say that a certain property of a system is robust? Intuitively, robustness implies that, even under the effect of external perturbations on the system, no matter how strong or random, said property remains unchanged. In mathematics, properties of an object that are robust against deformations are called topological. For example, the letters s, S, and L can be transformed into each other by stretching or bending their shape. The same holds true for letters o, O, and D.

Scientists have identified five new plant species in the Bolivian Andes.

The species are all part of the genus Jacquemontia, which are twining or trailing plants with pretty blue flowers.

With rapid biodiversity loss taking place across South America and worldwide, identifying plant species is a vital step towards protecting them.

After gaining world attention by 'unboiling' egg protein, Flinders University scientists have now used an Australian-made novel thin film microfluidic device to manipulate Beta-lactoglobulin (β-lactoglobulin), the major whey protein in cow's, sheep's and other mammals milk.

The so-called Vortex Fluidic Device has previously been used in an array of experiments to successfully 'un-boil' egg protein and even break the molecular bonds of one of the world's hardest material, carbon nanotubes.
