Moles stop growing when they reach a certain size due to normal interactions between cells, despite having cancer-associated gene mutations, says a new study published today in eLife.
The findings in mice could help scientists develop new ways to prevent skin cancer growth that take advantage of the normal mechanisms that control cell growth in the body.
Mutations that activate the protein made by the BRAF gene are believed to contribute to the development of skin cancer. However, recent studies have shown that these mutations do not often cause skin cancer, but instead result in the formation of completely harmless pigmented moles on the skin. In fact, 90% of moles have these cancer-linked mutations but never go on to form tumours. “Exploring why moles stop growing might lead us to a better understanding of what goes wrong in skin cancer,” says lead author Roland Ruiz-Vega, a postdoctoral researcher at
It’s been three years since the landmark detection of a neutron star merger from gravitational waves. And since that day, an international team of researchers led by University of Maryland astronomer Eleonora Troja has been continuously monitoring the subsequent radiation emissions to provide the most complete picture of such an event.
Their analysis provides possible explanations for X-rays that continued to radiate from the collision long after models predicted they would stop. The study also reveals
A research collaboration between Queen Mary University of London, the University of Cambridge and the Institute for High Pressure Physics in Troitsk has discovered the fastest possible speed of sound.
The result- about 36 km per second — is around twice as fast as the speed of sound in diamond, the hardest known material in the world.
Waves, such as sound or light waves, are disturbances that move energy from one place to another. Sound waves can travel through different mediums, such as air or water, and move at different speeds depending on what they’re travelling through. For example, they move through solids much faster than they would through liquids or gases, which is why you’re able to hear an approaching train much faster if you listen to the sound propagating in the rail track rather than through the air.
Einstein’s theory of special relativity sets the absolute speed limit
Experiential museums—designed to provide visitors with interactive experiences—faced a big problem as coronavirus restrictions were eased: How to boost sanitization measures while demonstrating to visitors that these high-touch spaces were still safe to enter and enjoy.
Many operators of such spaces say they have been able to retain their interactive, immersive identities to a surprising degree as they and their guests navigate the challenges of the coronavirus pandemic.
The masks now required for visitors six years old and up might have made it harder to pick up the scents of the Chromaroma exhibit, for example, at the Houston outpost of the Color Factory, an art exhibit dedicated to color. So the museum amplified the scents.
The Color Factory’s ball pits in Houston and New York now require everyone over a certain age to wear a
Quibi founder Jeffrey Katzenberg is reportedly having a hard time finding a buyer for the struggling short-form video streaming service, after being rebuffed by Apple.
Short-form video streaming service Quibi is said to be exploring “strategic options,” including the possibility of a sale, after failing to hit initial subscriber targets. Thus far, however, it has come up short.
According to The Information, Katzenberg has recently pitched the possibility of acquiring Quibi several technology and entertainment companies. Some of the executives he approach include Eddy Cue, Apple’s senior vice president of internet software and services. Katzenberg was turned down.
Quibi was floated as a possible target of an Apple takeover earlier in 2020. Along with Apple, Katzenberg’s pitch was also rejected by WarnerMedia CEO Jason Kilar and Facebook app chief Fidji Simo, The Information reported.
Part of the reason why buyers keep turning the service down is that it doesn’t
An awful lot of time elapsed between the day Roger Penrose was walking to work in 1964 and the moment his phone rang while he was in the shower on the morning of Oct. 6, 2020. Back then, his walk was interrupted by “some strange feeling of elation,” as he told the Associated Press yesterday, about the moment he had his first glimmers of insight into the equations that would eventually make him famous. It was surely with another kind of elation that he answered his phone yesterday to learn that those same equations—which were the first to prove the existence of black holes—had earned the 89-year-old University of Oxford mathematical physicist the 2020 Nobel Prize in Physics.
Penrose was not alone alone in his delight. Also honored this year were astronomers Andrea Ghez, 55, of the University of California, Los Angeles; and Reinhard Genzel, 68, of the Max
BROOKFIELD — Thousands of Connecticut cemeteries are struggling to find the next generation to take over for their aging volunteers, raising concerns about what that means for the millions of dollars in their charge and the care of those interred there.
“There’s a huge gap here,” said Jeff Nolan, Central Cemetery Association’s treasurer. “The question is why is that gap remaining?”
Central Cemetery Association in Brookfield, which oversees Laurel Hill Cemetery, has spent three years trying to address the issue, but keeps hitting walls when seeking help.
“The remarkable indifference to this is a concern,” Nolan said.
The unsurety surrounding the future has led the association to consider forgoing volunteers moving forward and hiring full-time staff members that can oversee the cemeteries using the needed technology and training. They hope to do this by having associations partner up, join cemeteries that already have these resources or have regional government organizations
Netflix has added a new tab called “New & Popular” to its connected TV app that focuses on the biggest current and upcoming titles on the service.
Netflix’s New & Popular tab has an all-new section called “Worth the Wait” that includes movies, shows, and specials that are up to 365 days from being released.
Netflix plans to start testing this new tab on the web before the end of the year.
One of Netflix’s persistent problems is that unless you know exactly what you watch to watch, you might spend hours scrolling through menus. That’s not to say that it’s hard to find content relevant to your interests, but the home screen of the app can be overwhelming. Making matter worse is the fact that Netflix has always struggled to split its content up into easily-identifiable categories, but perhaps the latest update —
Researchers off the coast of Nova Scotia found a nearly 2-ton great white shark believed to be roughly 50 years old, dubbing her a true “Queen of the Ocean.”
Coming in at more than 17 feet long and 3,541 pounds, she is the largest shark the group has been able to sample in the Northwest Atlantic, according to a Friday Facebook post by OCEARCH, a non-profit marine research organization. She’s been named Nukumi for “the legendary wise old grandmother figure” of the Indigenous Mi’kmaq people, a First Nations group native to that region of Canada.
Chris Fischer, the OCEARCH expedition leader, called Nukumi a “proper Queen of the Ocean” in a video log posted Saturday.
“She’s probably 50-years-old and certainly her first litters of pups she would have been having 30 years ago are also making babies, really humbling to stand next to a large animal like that,” Fischer said.
