Green manufacturing is becoming an increasingly critical process across industries, propelled by a growing awareness of the negative environmental and health impacts associated with traditional practices. In the biomaterials industry, electrospinning is a universal fabrication method used around the world to produce nano- to microscale fibrous meshes that closely resemble native tissue architecture. The process, however, has traditionally used solvents that not only are environmentally hazardous but also pose a significant barrier to industrial scale-up, clinical translation, and, ultimately, widespread use. from Phys.org - latest science and technology news stories https://ift.tt/3BZXYXJ

We humans aren't the only animals that have to worry about bug bites. There are thousands of insect species that have evolved to specialize in feeding on different mammals and birds, but scientists are still learning how these bugs differentiate between species to track down their preferred prey. It turns out, the attraction might not even be skin-deep: a new study in Molecular Ecology found evidence that blood-sucking flies that specialize on bats may be locating their preferred hosts by following the scent of chemicals produced by bacteria on the bats' skin. from Phys.org - latest science and technology news stories https://ift.tt/2TLkbb1

Frontotemporal dementias are a group of fatal and debilitating brain disorders for which there are no cures. Researchers describe how they were able to recreate much of the damage seen in a widely studied form of the disease by growing special types of cerebral organoids in petri dishes. This form of the disease is caused by a genetic mutation in tau, a protein that is a hallmark of Alzheimer's disease and other dementias. By studying these organoids, the scientists discovered how the mutated tau protein may trigger the death of a specific class of neurons known to be vulnerable in frontotemporal dementia. They also showed that they could prevent the death of these neurons by treating the organoids with an experimental drug, originally designed to combat Crohn's disease. from Latest Science News -- ScienceDaily https://ift.tt/3f0btgc

Astronomers have discovered the shortest-ever gamma-ray burst (GRB) caused by the implosion of a massive star. Using the international Gemini Observatory, a program of NSF's NOIRLab, astronomers identified the cause of this 0.6-second flurry of gamma rays as a supernova explosion in a distant galaxy. GRBs caused by supernovae are usually more than twice as long, which suggests that some short GRBs might actually be imposters—supernova-produced GRBs in disguise. from Phys.org - latest science and technology news stories https://ift.tt/2TCTQfd

Researchers at North Carolina State University have demonstrated a low-cost technique for retrieving nanowires from electronic devices that have reached the end of their utility, and then using those nanowires in new devices. The work is a step toward more sustainable electronics. from Phys.org - latest science and technology news stories https://ift.tt/3iKwz3o

Heatwaves that obliterate temperature records as in western Canada last month and Siberia last year are caused by the rapid pace, rather than the amount, of global warming, researchers said Monday. from Phys.org - latest science and technology news stories https://ift.tt/3BGOSzd

Norwegian experts say an unusually large meteor was visible over large parts of southern Scandinavia and illuminated southeast Norway with a powerful flash of light for a few seconds as many observers were reported to also hear a roaring sound afterwards. from Phys.org - latest science and technology news stories https://ift.tt/2UPmfza

Computers have been able to quickly process 2D images for some time. Your cell phone can snap digital photographs and manipulate them in a number of ways. Much more difficult, however, is processing an image in three dimensions, and doing it in a timely manner. The mathematics are more complex, and crunching those numbers, even on a supercomputer, takes time. from Phys.org - latest science and technology news stories https://ift.tt/3i5fgLn
