Rare Peacock Stars Could Potentially Detonate Deadly Gamma Rays In The Milky Way [Video]

KEY POINTS

  • Gamma-ray bursts are one of the most energetic occurrences in the universe
  • Apep’s two stars are 10 to 15 times more massive and 100,000 times brighter than the Sun
  • The two stars also orbit each other about every 125 years

Apep, one of the Wolf-Rayets binary star systems dubbed as the “exotic peacocks of the stellar world” discovered in 2018, was found to have the capacity to detonate long gamma ray bursts that are potentially deadly. If it detonates, the explosion could be something never seen in the Milky Way before, according to scientists.

“As well as exhibiting all the usual extreme behavior of Wolf-Rayets, Apep’s main star looks to be rapidly rotating. This means it could have all the ingredients to detonate a long gamma-ray burst when it goes supernova,” Peter Tuthill, study lead and professor from the University of Sydney, said in a press release.

Stacking and twisting graphene unlocks a rare form of magnetism

Since the discovery of graphene more than 15 years ago, researchers have been in a global race to unlock its unique properties. Not only is graphene—a one-atom-thick sheet of carbon arranged in a hexagonal lattice—the strongest, thinnest material known to man, it is also an excellent conductor of heat and electricity.


Now, a team of researchers at Columbia University and the University of Washington has discovered that a variety of exotic electronic states, including a rare form of magnetism, can arise in a three-layer graphene structure.

The findings appear in an article published Oct. 12 in Nature Physics.

The work was inspired by recent studies of twisted monolayers or twisted bilayers of graphene, comprising either two or four total sheets. These materials were found to

Extremely rare wildcat resembling a leopard seen on Texas trail camera. What is it?

A large wildcat resembling a leopard was recently photographed by a U.S. Fish and Wildlife Service trail camera in Texas.

The nighttime image was shared Saturday on Facebook, showing the “majestic feline” as it was creeping into a highway underpass, used by wildlife to avoid traffic.

Though the spotted wildcat looks alarmingly like a leopard — particularly in black and white — experts have identified it as an ocelot, a native species of wild feline that grows to 4 feet in length and 35 pounds. (Leopards grow to more than 6 feet and 130 pounds, LiveScience.com reports.)

To say the species is rare in the U.S. is an understatement.

“There are an estimated 50 ocelots that remain in the United States,” U.S. Fish and Wildlife officials say. “Known as the ‘little leopard,’ ocelots are larger than a house cat but smaller than a bobcat.”

This endangered and elusive wildcat was recently spotted using a wildlife underpass in Texas. It’s an ocelot and there are fewer than 50 living in the wild in the nation.

Geologists solve puzzle that could predict valuable rare earth element deposits

Pioneering new research has helped geologists solve a long-standing puzzle that could help pinpoint new, untapped concentrations of some the most valuable rare earth deposits.


A team of geologists, led by Professor Frances Wall from the Camborne School of Mines, have discovered a new hypothesis to predict where rare earth elements neodymium and dysprosium could be found.

The elements are among the most sought after, because they are an essential part of digital and clean energy manufacturing, including magnets in large wind turbines and electric cars motors.

For the new research, scientists conducted a series of experiments that showed sodium and potassium—rather than chlorine or fluorine as previously thought—were the key ingredients for making these rare earth elements soluble.

This is crucial as it determines whether they crystalise — making them fit for extraction — or stayed dissolved in fluids.

Save $50 on Latest iPad Pro 11.0 With This Rare Early Prime Day Deal

Andy Boxall/DigitalTrends

If you are looking to take advantage of Prime Day deals to purchase a premium tablet, then you’re in luck. It’s rare to see discounts for newly released Apple products, but they do happen every once in a while. A perfect example is this early Prime Day deal for the Wi-Fi model of the 11-inch, 128GB version of the fourth-generation iPad Pro. The offer, which joins the list of Prime Day iPad deals ahead of the October 13-14 event, cuts $50 off the tablet’s price to take it down to $750 from $800.

Apple, which released the fourth-generation iPad Pro in March, claims that the tablet powered by the A12Z chip is faster and more powerful than most Windows laptops. The latest version of the iPad Pro, however, remains easy to handle with a width of only 5.9mm and weight of only 471 grams. The Liquid Retina IPS

Double jeopardy for ecologically rare birds and terrestrial mammals

Common assumptions notwithstanding, rare species can play unique and essential ecological roles. After studying two databases that together cover all known terrestrial mammals and birds worldwide, scientists from the CNRS, the Foundation for Biodiversity Research (FRB), Université Grenoble Alpes, and the University of Montpellier have demonstrated that, though these species are found on all continents, they are more threatened by human pressures than ecologically common species and will also be more impacted by future climate change. Thus, they are in double jeopardy. The researchers’ findings, published in Nature Communications (October 8, 2020), show that conservation programs must account for the ecological rarity of species.


It has long been thought that rare species contribute little to the functioning of ecosystems. Yet recent studies have discredited that idea: Rarity is a matter not only of the abundance or geographical range of a species, but also of the distinctiveness

Rare Earth Metals Get The Presidential Treatment

Last Wednesday, the president signed an executive order addressing the threat posed by the United States’ overreliance on “critical minerals” from “foreign adversaries.”

To be more specific, “critical minerals” here means “rare earth metals,” and “foreign adversaries” means “China.”

Although not as rare as gold, the group of 17 metals are used in the manufacture of advanced technologies, including electric vehicles, wind turbines and missile guidance systems. Your iPhone contains a number of them. Each F-35 fighter jet has about half a ton of these strategic elements.

The problem is that the U.S. no longer produces barite (used in fracking), gallium (semiconductors, 5G telecommunications), graphite (smartphone batteries) and a number of other materials. “For 31 of the 35 critical minerals, the United States imports more than half of its annual consumption,” according to the press release.

Today, China controls some 80 percent to 95 percent of the world market,
