PROVIDENCE, R.I. [Brown University] — Anyone who’s ever done a belly flop into a swimming pool knows it ends with a blunt-sounding splat, a big splash and a searing red sting. What most people don’t know is why. Daniel Harris does. The assistant professor in Brown University’s School of Engineering says the physics behind the phenomenon aren’t too complex. What happens — and what makes it so painful, he explains — is that the forces from the water surface put up a fierce resistance to the body suddenly going from air to water, which is often still. “All of a sudden, ...

Scientists have made a major breakthrough in the study of species evolution, and provided further evidence that state-of-the-art visual technology can be used to track the tiniest changes in different organisms’ development. New research used a combination of robotic video microscopes and computer vision to measure all of the observable characteristics of embryos of three different species. These measurements were recorded as spectra of energy and, through this, scientists were able to compare shifts between species alongside previously documented differences in the timing of discrete developmental ...

Korea Electrotechnology Research Institute (KERI) has developed a world-class 'eco-friendly insulating gas' that replaces SF6 (sulfur hexafluoride), the main cause of global warming in the field of electric power equipment, and developed a design technology to make it applicable to ultra-high voltage transmission circuit breakers.   Of course, power devices must be able to conduct electricity well but an ‘insulation’ function to block electricity is also essential to prepare for unexpected accidents and for safety reasons. SF6 gas offers excellent insulation and with far superior arc extinguishing performance than any other ...

Pediatric Emergency Department (ED) visits for firearm injuries doubled during the pandemic compared to earlier trends, according to a multicenter study published in the journal Pediatrics. During this time, deaths from firearm injuries in children and adolescents that occurred after arrival to the hospital also doubled – up from 3 percent of ED visits pre-pandemic to 6 percent of ED visits during the pandemic. “With the pandemic we saw a drastic increase in firearm purchases, which might have led to the tragic spikes in injuries and deaths from firearms among children ...

People who have a higher biological age than their actual chronological age have a significantly increased risk of stroke and dementia, especially vascular dementia. These are the results of a study from Karolinska Institutet in Sweden published in the Journal of Neurology, Neurosurgery and Psychiatry. The study, which was led by Sara Hägg, associate professor, and Jonathan Mak, doctoral student at the Department of Medical Epidemiology and Biostatistics, Karolinska Institutet, shows that the increased risk persists even if other risk factors such as genetics, lifestyle and socioeconomics are taken into account. As we age, the risk of chronic diseases such as ...

-With pictures- A new study reveals that supermassive black holes at the centres of galaxies, known as quasars, can sometimes be obscured by dense clouds of gas and dust in their host galaxies. This challenges the prevailing idea that quasars are only obscured by donut-shaped rings of dust in the close vicinity of the black hole. Quasars are extremely bright objects powered by black holes gorging on surrounding material. Their powerful radiation can be blocked if thick clouds come between us and the quasar. Astronomers have long thought this obscuring material only exists in the quasar's immediate surroundings, in a "dusty torus" (or donut) encircling it. Now, a team of ...

EMBARGOED: 0001 GMT MONDAY 6 NOVEMBER 2023 New materials developed at the University of Surrey could pave the way for a new generation of flexible X-ray detectors, with potential applications ranging from cancer treatment to better airport scanners.   Traditionally, X-ray detectors are made of heavy, rigid material such as silicon or germanium.

Melon (Cucumis melo L.) is an important vegetable crop that has an extensive history of cultivation, and has been classified into two subspecies, C. melo ssp. agrestis and C. melo ssp. melo. Previous study suggested that the two subspecies were domesticated independently [1], which may have generated different genetic mechanisms for the same trait between the two subspecies. Furthermore, the difference in their geographical distribution resulted in diverse characteristics between the two subspecies, shaping genomic imprinting in their genomes. Wild germplasm is an important genetic resource in crop breeding because of its high genetic diversity ...

Ever since the discovery of the Higgs boson in 2012, physicists have wanted to build new particle colliders to better understand the properties of that elusive particle and probe elementary particle physics at ever-higher energy scales. The trick is, doing so takes energy – a lot of it. A typical collider takes hundreds of megawatts – the equivalent of tens of millions of modern lightbulbs – to operate. That's to say nothing of the energy it takes to build the devices, and it all adds ...

November 3, TORONTO — Scientists at the Ontario Institute for Cancer Research (OICR) have uncovered one way tobacco smoking causes cancer and makes it harder to treat by undermining the body’s anti-cancer safeguards. Their new study, published today in Science Advances, links tobacco smoking to harmful changes in DNA called ‘stop-gain mutations’ that tell the body to stop making certain proteins before they are fully formed. They found that these stop-gain mutations were especially prevalent in genes known as ‘tumour-suppressors’, ...
