CAPE CANAVERAL, Fla. (AP) — A NASA spacecraft has officially “touched” the sun, plunging through the unexplored solar atmosphere known as the corona.

Scientists announced the news Tuesday during a meeting of the American Geophysical Union.

The Parker Solar Probe actually flew through the corona in April during the spacecraft’s eighth close approach to the sun. Scientists said it took a few months to get the data back and then several more months to confirm.

Circa 2009 real teleportation not just in the quantum realm.

Ground-state entanglement induces emergence of negative-energy-density regions in quantum systems by squeezing zero-point oscillation, keeping total energy of the systems nonnegative. By use of the negativity of quantum energy density, protocols of quantum energy teleportation are proposed that transport energy to distant sites by local operations and classical communication. The energy is teleported without breaking any physical laws including causality and local energy conservation. Because intermediate subsystems of the energy transfer channel are not excited during the protocol execution, the protocol attains energy transportation without heat generation in the channel. We discuss the protocol focusing around qubit chains. In addition, we address a related problem of breaking ground-state entanglement by measurements.

Working with Intel, Dell has created a new laptop called Concept Luna with the aim of making future PCs easier to repair, reuse and recycle. Dell said that if it incorporated all the design ideas, it could reduce a computer’s carbon footprint by up to 50 percent compared to current laptop models.

A key feature of Concept Luna is the redesigned components and a new, more efficient layout. To start with, the motherboard is 75 percent smaller at just 5,580 square millimeters and has a 20 percent lower component count. Everything is rearranged, with the motherboard close to the top cover to expose it to a larger cooling area. It’s also separated from the battery charging unit in the base, allowing better passive cooling that could eliminate the need for a fan.

The extra efficiencies also reduce power requirements, allowing the designers to use a smaller battery with deep-cycle cells that offer a “long charge that can be maintained across many years of use, increasing refurbishment and reuse beyond the first product life it services,” Dell said.

Physicists from Trinity have unlocked the secret that explains how large groups of individual “oscillators”—from flashing fireflies to cheering crowds, and from ticking clocks to clicking metronomes—tend to synchronize when in each other’s company.

Their work, just published in the journal Physical Review Research, provides a mathematical basis for a phenomenon that has perplexed millions—their newly developed equations help explain how individual randomness seen in the natural world and in electrical and computer systems can give rise to synchronization.

We have long known that when one clock runs slightly faster than another, physically connecting them can make them tick in time. But making a large assembly of clocks synchronize in this way was thought to be much more difficult—or even impossible, if there are too many of them.

The newest emotion theory explains what leads your emotions to flip on and off.

Martin Shaw thought he would lose his hand after he severely injured it in a car crash, but a wartime technique saved it.

Their inner workings reside in the realm of physics, but lasers make everyday life possible. Talking on a cell phone or googling COVID stats while your apples and oranges are scanned at the checkout counter—lasers at every step.

Lasers emit intense light at specific wavelengths. At one wavelength, laser beams etch patterns on computer chips that define their circuitry. At telecom wavelengths, lasers fire the enormous volumes of data through optical fibers that make ours the information age.

In 2017, a new kind of laser invented by electrical engineer Boubacar Kante, Ph.D., was recognized as one of the breakthrough inventions of the year by Physics World. With his Bakar Fellows support, Kante is preparing to fabricate a prototype of the new laser and demonstrate its potential for a range of applications from microsurgery to satellite telemetry.

The first volunteer in a Phase I clinical trial of an oral COVID-19 vaccine developed by an Israeli-American company has been screened and enrolled, according to Oravax Medical, a subsidiary of Oramed Pharmaceuticals.

The trial is taking place in South Africa.

Oramed Pharmaceuticals, a clinical-stage pharmaceutical company, is based on technology developed by Hadassah-University Medical Center and run by Israeli CEO Nadav Kidron.
