You’ve probably seen some of the cool things magnets can do. Place one near a paper clip, and the clip zooms across the table toward the magnet. Hold one magnet near another, and the second one mysteriously darts in the opposite direction. If you didn’t know about science, magnet tricks might seem like magic tricks.

Now, scientists have discovered another magnetic trick. By mixing unbelievably small magnets with oil, bigger magnets can be used to move the oily globs around. The trick isn’t just cool to watch. Some day, the technique could help clean up messy oil spills in the sea mistakenly dumped by ships.

Researchers at Carnegie Mellon University in Pittsburgh make teeny tiny magnets out of two metals: iron and cobalt. Unlike the palm-sized magnets you may have played with in school, these magnets are measured in nanometers. One nanometer equals one-billionth of a meter. That may be hard to picture, so think of this: A human hair is about 80,000 nanometers wide.(Read this story to learn more.)

I think these can be fought with current technology such as quantum radar even other higher level technology. It can also be hacked with quantum radar or neutrino beams.

Know colloquially as the “Black Holes” by the U.S. Navy, the Improved-Kilo-class of submarines are quite deadly — and could turn the balance of power in the South China Sea in China’s favor.

Clause density is something new to me but seems interesting as I know shores algorithm is the only thing that can hack systems.

Google is racing to develop quantum-enhanced processors that utilize quantum mechanical effects to one day dramatically increase the speed at which data can be processed.

In the near term, Google has devised new quantum-enhanced algorithms that operate in the presence of realistic noise. The so-called quantum approximate optimization algorithm, or QAOA for short, is the cornerstone of a modern drive towards noise-tolerant quantum-enhanced algorithm development.

The celebrated approach taken by Google in QAOA has sparked vast commercial interest and ignited a global research community to explore novel applications. Yet, little actually remains known about the ultimate performance limitations of Google’s QAOA algorithm.

I frankly think this of exotic species unknown but it has exotic movement.

With over 4,000 exoplanets found so far, it takes a particularly interesting one to stand out.

LHS 1815b literally does that. While most planet-bearing stars we find orbit the Milky Way in the plane of its disk, this planet’s host star’s orbit takes it well out of that plane, flying way up over the galaxy and way down below it over time, giving it a pretty interesting view of our galaxy.

The Infinity Stones have played a key role in some of the Marvel Universe’s most defining moments, and now they’ve returned in the hands of Marvel’s most popular new characters. The chase for the powerful Infinity Stones will play out in INFINITE DESTINIES, launching this summer!

In a series of eight annuals, each installment will pair Marvel’s biggest heroes like Captain America and Iron Man with some of Marvel’s newest heroes and villains including Star, Amulet, and more. These exciting new additions to the Marvel mythos may or may not possess one of the sought after stones — but the real question will be who will be holding them in the end, and what will it mean for the future of the Marvel Universe?

“We’ve had a wave of incredible new characters over the last few years, and INFINITE DESTINIES will shine a light on eight of them,” Editor Nick Lowe said. “We’ll discover new aspects of these heroes and villains in adventures with our the most archetypal Marvel heroes.”

Last April, the Event Horizon Telescope (EHT) sparked international excitement when it unveiled the first image of a black hole. Today, a team of researchers have published new calculations that predict a striking and intricate substructure within black hole images from extreme gravitational light bending.

“The image of a black hole actually contains a nested series of rings,” explains Michael Johnson of the Center for Astrophysics, Harvard and Smithsonian (CfA). “Each successive ring has about the same diameter but becomes increasingly sharper because its light orbited the black hole more times before reaching the observer. With the current EHT image, we’ve caught just a glimpse of the full complexity that should emerge in the image of any black hole.”

Because black holes trap any photons that cross their event horizon, they cast a shadow on their bright surrounding emission from hot infalling gas. A “photon ring” encircles this shadow, produced from light that is concentrated by the strong gravity near the black hole. This photon ring carries the fingerprint of the black hole—its size and shape encode the mass and rotation or “spin” of the black hole. With the EHT images, black hole researchers have a new tool to study these extraordinary objects.

The oldest fossil of a modern bird yet found, dating from the age of dinosaurs, has been identified by an international team of palaeontologists.

The spectacular fossil, affectionately nicknamed the ‘Wonderchicken’, includes a nearly complete , hidden inside nondescript pieces of rock, and dates from less than one million years before the asteroid impact which eliminated all large dinosaurs.

Writing in the journal Nature, the team, led by the University of Cambridge, believe the new fossil helps clarify why survived the mass extinction event at the end of the Cretaceous period, while the giant dinosaurs did not.
