A team of North Hollywood High School science students emerged victorious Saturday over scholars from 63 other schools nationwide in this year’s U.S. Department of Energy Office of Science National Science Bowl Championship.

The win marks North Hollywood High’s second National Science Bowl championship, following the title captured in 2001.

The school has placed among the top five teams 12 times at the national event.

Many features in Jupiter’s highly dynamic atmosphere are short lived, but the April 2021 observation from the JunoCam instrument (top image) revealed that nearly one year after its discovery, the remnant of Clyde’s Spot had not only drifted away from the Great Red Spot but had also developed into a complex structure that scientists call a folded filamentary region. This region is twice as big in latitude and three times as big in longitude as the original spot, and has the potential to persist for an extended period of time.

The lower image was taken on June 2, 2020, around 3:56 a.m. when the spacecraft was about 28000 miles (45000 kilometers) from Jupiter’s cloud tops. The upper image was taken on April 15, 2021, at 4:58 p.m. PDT (7:58 p.m. EDT). At the time, the spacecraft was about 16800 miles (27000 kilometers) from Jupiter’s cloud tops, at a latitude of about 30 degrees South. Another citizen scientist, Kevin M. Gill, processed both images from raw JunoCam data.

JunoCam’s raw images are available for the public to peruse and process into image products at https://missionjuno.swri.edu/junocam/processing.

Virgin Galactic on Saturday made its first rocket-powered flight from New Mexico to the fringe of space in a manned shuttle, as the company forges toward offering tourist flights to the edge of the Earth’s atmosphere.

High above the desert in a cloudless sky, the VSS Unity ignited its rocket to hurtle the ship and two pilots toward space. A live feed by NASASpaceFlight.com showed the ship accelerating upward and confirmed a landing later via radar.

We have developed and tested a secure new computer processor that thwarts hackers by randomly changing its underlying structure, thus making it virtually impossible to hack.

Last summer, 525 security researchers spent three months trying to hack our Morpheus processor as well as others. All attempts against Morpheus failed.

This study was part of a program sponsored by the U.S. Defense Advanced Research Program Agency to design a secure processor that could protect vulnerable software. DARPA released the results on the program to the public for the first time in January 2021.

Here’s how to create a single model, rather than a set of related but separate models, to power a process or product.

Physicists in Germany say they have found definitive evidence for the existence of superfluidity in an extremely cold 2D gas of fermions. Their experiment involved confining a few thousand lithium atoms inside a specially-designed trap, and they say that the finding could help shed light on the role of reduced dimensionality in high-temperature superconductors.

Understanding the mechanisms that allow electrical current to flow without resistance inside cuprate materials at ambient pressure and at temperatures of up to 133 K is one of the biggest outstanding challenges in condensed-matter physics. Although scientists can explain the process behind more conventional, lower-temperature superconductivity, they are still trying to work out how the phenomenon can take place at high temperatures in what are essentially 2D materials (cuprates being made up of layers of copper oxide). Such low-dimensional materials are prone to fluctuations that prevent the long-range coherence thought to be essential for superconductivity.

2D Fermi gases can serve as model systems to try and help clear up this mystery, having strong and tuneable correlations between their constituent fermions that can mimic interactions in superconductors. Macroscopic quantum phenomena such as Bose-Einstein condensation involve large numbers of bosons – particles with integer spin – co-existing in a single quantum state. Fermions, in contrast, have half-integer spin and are subject to the Pauli exclusion principle – which precludes multiple particles sharing quantum states. But fermions can get around this restriction by pairing up and combining their spins.

Artificial intelligence tool can be used for long-term tracking and management of chronic gastrointestinal ailments.

An artificial intelligence tool under development at Duke University can be added to the standard toilet to help analyze patients’ stool and give gastroenterologists the information they need to provide appropriate treatment, according to research that was selected for presentation at Digestive Disease Week® (DDW) 2021. The new technology could assist in managing chronic gastrointestinal issues such as inflammatory bowel disease (IBD) and irritable bowel syndrome (IBS).

“Typically, gastroenterologists have to rely on patient self-reported information about their stool to help determine the cause of their gastrointestinal health issues, which can be very unreliable,” said Deborah Fisher, MD, one of the lead authors on the study and associate professor of medicine at Duke University Durham, North Carolina. “Patients often can’t remember what their stool looks like or how often they have a bowel movement, which is part of the standard monitoring process. The Smart Toilet technology will allow us to gather the long-term information needed to make a more accurate and timely diagnosis of chronic gastrointestinal problems.”
