Researchers have discovered how superfluid helium 3He would feel if you could put your hand into it. The interface between the exotic world of quantum physics and classical physics of the human experience is one of the major open problems in modern physics. Nobody has been able to answer this question during the 100-year history of quantum physics.

Single-photon emitters quantum mechanically connect quantum bits (or qubits) between nodes in quantum networks. They are typically made by embedding rare-earth elements in optical fibers at extremely low temperatures. Now, researchers have developed an ytterbium-doped optical fiber at room temperature. By avoiding the need for expensive cooling solutions, the proposed method offers a cost-effective platform for photonic quantum applications.

Broadly neutralizing antibodies are already being used to fight viruses. This approach could also help to treat infections with multi-resistant bacteria in the future.

Our understanding of how cells recycle lipids through autophagy -- a form of cellular degradation -- has grown significantly, thanks to a recent study. Using yeast as a model organism, the researchers explored the molecular mechanisms leading to the degradation of the phospholipid bilayers making up the cell membranes. Their findings improve our understanding of cellular degradation processes and related metabolic disorders.

Though beer is a popular drink worldwide, it's usually made from barley, which leaves those with a gluten allergy or intolerance unable to enjoy the frothy beverage. Sorghum, a naturally gluten-free grain, could be an alternative, but complex preparation steps have hampered its widespread adoption by brewers. Now, researchers reporting the molecular basis behind sorghum brewing have uncovered an enzyme that could improve the future of sorghum-based beers.

Researchers have genetically engineered the first mice that get a human-like form of COVID-19, according to a new study.

A new study that combines genetic and molecular techniques helps solve the riddle of sea star (commonly called starfish) body plans, and how sea stars start life with bilateral body symmetry -- just like humans -- but grow up to be adults with fivefold 'pentaradial' symmetry.

A new analysis of the bones and muscles in ancient fish gives new clues about how the shoulder evolved in animals -- including us.

Local hunters in the Icefjord near Ilulissat have long known about a special ringed seal -- the Kangia seal -- which is significantly larger and has a markedly different fur color and pattern than typical Arctic ringed seals. Now scientific studies have shown that the Kangia ringed seal has been isolated from other ringed seals for a long period of time -- more than 100,000 years.

New research combining computer modeling and experiments with macaques shows the body's immune system helps control human immunodeficiency virus (HIV) infections largely by suppressing viral production in already infected cells while also killing viral infected cells, but only within a narrow time window at the start of a cell's infection.

The world's largest dam removal and restoration project currently underway on the Klamath River in Oregon and California will aid salmon populations that have been devastated by disease and other factors. However, it will not fully alleviate challenges faced by the species, a team of researchers conclude.

Significant differences in the gene activity of the fetal intestine, brain and placenta were identified, depending on the microbes in the mother's body and the compounds produced by them. The findings indicate that maternal microbes are important to her offspring's development and health.

Many hidden genetic variations can be detected with Chameleolyser, a new method. The information is already yielding new patient diagnoses and may also lead to the discovery of as yet unknown disease genes.

Mountains of used plastic bottles get thrown away every day, but microbes could potentially tackle this problem. Now, researchers report that they've developed a plastic-eating E. coli that can efficiently turn polyethylene terephthalate (PET) waste into adipic acid, which is used to make nylon materials, drugs and fragrances.

Researchers combined physics and machine learning to develop a new 3D-printing technique that can quickly create complex physical patterns -- including replicating a segment of a Pollock painting -- by leveraging the same natural fluid instability that Pollock used in his work.

New research shows that potential adaptive responses by sea turtles, such as shifting the timing of when they nest, may not be enough to counteract the projected impacts from climate change on hatchling production.

Sunflowers famously turn their faces to follow the sun as it crosses the sky. But how do sunflowers 'see' the sun to follow it? Plant biologists show that they use a different, novel mechanism from that previously thought.

A team of animal scientists is set to deliver a potential game changer for subsistence farmers in Tanzania: cows that produce up to 20 times the milk of indigenous breeds.
