What a time to be alive… We are on the verge of discovering the fifth dimension and it will change everything we know about the Universe.
Scientists are sometimes questioned if they conduct fresh experiments in the lab or continue to repeat previous ones for which they have certain outcomes. While most scientists undertake the former, scientific advancement also relies on conducting the latter and validating whether what we think we know remains true in light of fresh knowledge.
Physicists has successfully developed a circuit capable of capturing graphene’s thermal motion and converting it into an electrical current.
First “decadal survey” into biological physics says further advances can only emerge in the subject with additional investment.
New research artificially creating a rare form of matter known as spin glass could spark a new paradigm in artificial intelligence by allowing algorithms to be directly printed as physical hardware. The unusual properties of spin glass enable a form of AI that can recognize objects from partial images much like the brain does and show promise for low-power computing, among other intriguing capabilities.
“Our work accomplished the first experimental realization of an artificial spin glass consisting of nanomagnets arranged to replicate a neural network,” said Michael Saccone, a post-doctoral researcher in theoretical physics at Los Alamos National Laboratory and lead author of the new paper in Nature Physics. “Our paper lays the groundwork we need to use these physical systems practically.”
Spin glasses are a way to think about material structure mathematically. Being free, for the first time, to tweak the interaction within these systems using electron-beam lithography makes it possible to represent a variety of computing problems in spin-glass networks, Saccone said.
Ernesto Di Maio is severely allergic to the yeast in leavened foods. “I have to go somewhere and hide because I will be fully covered with bumps and bubbles on the whole body,” he says. “It’s really brutal.”
Di Maio is a materials scientist at the University of Naples Federico II where he studies the formation of bubbles in polymers like polyurethane. He’s had to swear off bread and pizza, which can make outings in Italy a touch awkward. “It’s quite hard in Naples not to eat pizza,” he explains. “People would say, ‘Don’t you like pizza? Why are you having pasta? That’s strange.’”
So Di Maio put Iaccarino and another graduate student, Pietro Avallone, to work on a project to make pizza dough without yeast. The results of this scientific and culinary experiment are published in Tuesday’s edition of Physics of Fluids. Di Maio pulled in another colleague: chemical engineer Rossana Pasquino who studies the flow of materials, everything from toothpaste to ketchup to plastics. “Pizza [dough] is a funny material,” she explains, “because it flows, but it has to be also like rubber. It has to be elastic enough [when it’s cooked] to be perfect when you eat it.” — I had to post this because I love Pizza.
Bread geeks, take note! The new technique, developed in a lab in Naples, involves the smart application of materials science and physics to make airy, bubbly dough without fermentation.
Physicists at the University of Sussex have discovered that black holes exert a pressure on their environment, in a scientific first.
In 1974 Stephen Hawking made the seminal discovery that black holes emit thermal radiation. Previous to that, black holes were believed to be inert, the final stages of a dying heavy star.
The University of Sussex scientists have shown that they are in fact even more complex thermodynamic systems, with not only a temperature but also a pressure.
Star’s mysterious orbit around black hole proves einstein was right all along—again.
The star, known as S2, has a 16-year elliptical orbit. It came near 20 billion kilometers of our black hole, Sagittarius A*, last year. If Isaac Newton’s traditional definition of gravity is correct, S2 should then continue on its previous orbit’s course through space. But it didn’t work.
Instead, it took a slightly divergent route, with the axis of its ellipse altering slightly, according to research published today in Astronomy & Astrophysics by a team employing the European Southern Observatory’s Very Large Telescope. As predicted by general relativity, the process known as Schwarzschild precession will eventually force S2 to trace out a spirograph-like floral pattern in space (as illustrated above).
Mikhail Kokorich is the founder of Destinus. This serial entrepreneur has been dubbed Russia’s Elon Musk by his public relations team. The Russian businessman says his business, Destinus, is developing a hydrogen-powered, zero-emissions transcontinental delivery drone that can travel at speeds up to Mach 15.
Destinus plans to combine the technological advancements from a spaceplane with the ordinary and straightforward physics from a glider to create a hyperplane that will meet the many demands of a hyper-connected world.
This hyperplane will use clean hydrogen fuel to transport cargo between Europe and Australia in mere hours. The hyperplane will be fully autonomous; it will take off from ordinary runways, traveling leisurely to the coast before accelerating to supersonic speeds.
An “anti-universe” where time runs backwards could exist next to ours, according to a new study.
The theory involves the fact nature has fundamental symmetries and researchers think this could apply to the universe as a whole.
The theory has been explained in the journal Annals of Physics.
