Strongly interacting bosons have been predicted to display a transition into a superfluid ground state, similar to Bose–Einstein condensation. This effect is now observed in a double bilayer graphene structure, with excitons as the bosonic particles.

MIT physicists have created a superfluid gas, the so-called Bose-Einstein condensate, for the first time in an extremely high magnetic field. The magnetic field is a synthetic magnetic field, generated using laser beams, and is 100 times stronger than that of the world’s strongest magnets. Within this magnetic field, the researchers could keep a gas superfluid for a tenth of a second—just long enough for the team to observe it. The researchers report their results this week in the journal Nature Physics.
A superfluid is a phase of matter that only certain liquids or gases can assume, if they are cooled to extremely low temperatures. At temperatures approaching absolute zero, atoms cease their individual, energetic trajectories, and start to move collectively as one wave.
Superfluids are thought to flow endlessly, without losing energy, similar to electrons in a superconductor. Observing the behavior of superfluids therefore may help scientists improve the quality of superconducting magnets and sensors, and develop energy-efficient methods for transporting electricity.
Astronomers have detected an enormous extragalactic structure hiding in an uncharted region of space far beyond the Milky Way ‘s center.
This phantom region, known as the zone of avoidance, is a blank spot on our map of the universe, comprising somewhere between 10% and 20% of the night sky. The reason we can’t see it — at least with standard visible light telescopes — is because the Milky Way’s bulging center blocks our view of it; the center of our galaxy is so dense with stars, dust and other matter that light from the zone of avoidance gets scattered or absorbed before reaching Earth’s telescopes.
However, researchers have had better luck uncovering the zone’s secrets with telescopes that can detect infrared radiation — a type of energy that’s invisible to human eyes, but powerful enough to shine through dense clouds of gas and dust. Infrared surveys of the zone of avoidance have found evidence of thousands of individual galaxies shining through the cosmic fog, though little is known about the large-scale structures that lurk there.
Researchers revealed why cancer cells require proteins that fix copper ions in order to develop and spread throughout the human body. Possible novel treatment targets have been discovered as a result of recent research on the connections between proteins and how they bind to metals in cancer-related proteins.
Small amounts of the metal copper are required by human cells to perform essential biological functions. The conclusion drawn from studies demonstrating higher copper levels in tumor cells and blood serum from cancer patients is that cancer cells require more copper than healthy cells. Additionally, more copper-binding proteins are active when copper levels are higher. “Therefore, these proteins are highly important to study when it comes to understanding the development of cancer and deeper knowledge about them can lead to new targets for treatment of the disease,” said Pernilla Wittung-Stafshede, Professor of Chemical Biology at Chalmers University of Technology, Sweden.
Most cancer-related deaths are due to the fact that metastases — secondary tumors — form in several places in the body, for example, in the liver or lungs. A protein called Memo1 is part of the signaling systems that cancer cells use to grow and spread around the body. Previous research has shown that when the gene for Memo1 is inactivated in breast cancer cells, their ability to form metastases decreases. A research group from Chalmers wanted to take a closer look at the connection between Memo1 and copper. In a new study published in the scientific journal PNAS, the researchers examined the Memo1 protein’s ability to bind copper ions through a series of test tube experiments. They discovered that the protein binds copper, but only the reduced form of copper. It is this form of copper ions that is most common in living cells. It’s an important discovery because reduced copper, while it is needed in the body, also contributes to redox-reactions that damage — or even kill — the cells.
Unidentified hackers have stolen the health records of millions of customers of Australian health insurer Medibank, releasing them on the dark web.

South Australian artificial intelligence (AI) company GoMicro is rolling out its new grain assessment technology in Australia, paving the way towards more consistent quality controls and stable grain and pulse prices.
Based at Flinders University’s high-tech New Venture Institute (NVI) at Tonsley Innovation District in Clovelly Park, Adelaide, GoMicro CEO Dr. Sivam Krish says the multi-grain assessor gives growers and domestic and export markets a quick and better way to grade crops, accurately testing more than 1,200 grains in one sample—compared to the existing scanner-based method which assesses about 200 well-separated grains at a time.
“GoMicro relies on the excellent quality of phone cameras and Amazon web services to deliver low-cost, high-precision quality grain and other produce assessments to farmers worldwide,” says Dr. Krish.
University of Missouri researchers made the discovery while using bioluminescent imaging technology to study how nicotinamide riboside supplements work inside the body.
Commercial dietary supplements like nicotinamide riboside (NR), a form of vitamin B3, were linked to benefits related to cardiovascular, metabolic, and neurological health in previous studies. However, new research from the University of Missouri (MU) has found NR could actually increase the risk of serious disease, including developing cancer.
Supplements containing nicotinamide riboside are often marketed as NAD+ boosters claimed benefits including increased energy, anti-aging/longevity/healthy aging, improved cellular energy metabolism and repair, increased vitality, and improved heart health.
CAPE CANAVERAL, Fla — An unmanned U.S. military space plane landed early Saturday after spending a record 908 days in orbit for its sixth mission and conducting science experiments.
The solar-powered vehicle, which looks like a miniature space shuttle, landed at NASA’s Kennedy Space Center. Its previous mission lasted 780 days.
“Since the X-37B’s first launch in 2010, it has shattered records and provided our nation with an unrivaled capability to rapidly test and integrate new space technologies,” said Jim Chilton, a senior vice president for Boeing, its developer.
