Superfluids could share characteristic with common fluids      (via sciencedaily.com)     Original source 

Every fluid -- from Earth's atmosphere to blood pumping through the human body -- has viscosity, a quantifiable characteristic describing how the fluid will deform when it encounters some other matter. If the viscosity is higher, the fluid flows calmly, a state known as laminar. If the viscosity decreases, the fluid undergoes the transition from laminar to turbulent flow. The degree of laminar or turbulent flow is referred to as the Reynolds number, which is inversely proportional to the viscosity. However, this Reynolds similitude does not apply to quantum superfluids. A researcher has theorized a way to examine the Reynolds similitude in superfluids, which could demonstrate the existence of quantum viscosity in superfluids.

Small yet mighty: Showcasing precision nanocluster formation with molecular traps      (via sciencedaily.com)     Original source 

Nanoclusters (NCs) of transition metals like cobalt or nickel have widespread applications in drug delivery and water purification, with smaller NCs exhibiting improved functionalities. Downsizing NCs is, however, usually challenging. Now, scientists have demonstrated functional NC formation with atomic-scale precision. They successfully grew cobalt NCs on flat copper surfaces using molecular arrays as traps. This breakthrough paves the way for advancements like single-atom catalysis and spintronics miniaturization.

Back from the dead: Tropical tree fern repurposes its dead leaves      (via sciencedaily.com)     Original source 

Plant biologists report that a species of tree fern found only in Panama reanimates its own dead leaf fronds, converting them into root structures that feed the mother plant. The fern, Cyathea rojasiana, reconfigures these 'zombie leaves,' reversing the flow of water to draw nutrients back into the plant.

These male marsupials give up sleep for sex      (via sciencedaily.com)     Original source 

All animals need sleep. When humans or animals don't get enough, it can lead to trouble paying attention, irritability, and other ill effects. In a new study, researchers have made the surprising discovery that a small Australian marsupial called an antechinus will sacrifice hours of sleep per night to make more time for sex during the mating season.

New method flips the script on topological physics      (via sciencedaily.com)     Original source 

The branch of mathematics known as topology has become a cornerstone of modern physics thanks to the remarkable -- and above all reliable -- properties it can impart to a material or system. Unfortunately, identifying topological systems, or even designing new ones, is generally a tedious process that requires exactly matching the physical system to a mathematical model. Researchers have demonstrated a model-free method for identifying topology, enabling the discovery of new topological materials using a purely experimental approach.
