Researchers have long recognized that quantum communication systems would transmit quantum information more faithfully and be impervious to certain forms of error if nonlinear optical processes were used. However, past efforts at incorporating such processes could not operate with the extremely low light levels required for quantum communication.

Humans are better than current AI models at interpreting social interactions and understanding social dynamics in moving scenes. Researchers believe this is because AI neural networks were inspired by the infrastructure of the part of the brain that processes static images, which is different from the area of the brain that processes dynamic social scenes.

In many animals, skin coloration and its patterns play a crucial role in camouflage, communication, or thermoregulation. In the corn snake, some morphs display red, yellow, or pink blotches, and their dorsal spots can merge or turn into stripes. But which genetic and cellular mechanisms determine these colorful patterns? A team discovered that a single gene, CLCN2, is involved in these variations.

An international team has explored how in future aerial robots could process construction materials precisely in the air -- an approach with great potential for difficult-to-access locations or work at great heights. The flying robots are not intended to replace existing systems on the ground, but rather to complement them in a targeted manner for repairs or in disaster areas, for instance.

Irritable bowel syndrome, chronic itching, asthma and migraine are in many cases hard-to-treat conditions. They have in common that they are triggered by an excessive immune response -- which in severe cases can be life-threatening. A team of researchers has now identified a promising bioactive compound that could effectively reduce symptoms and slash fatality risk. The compound blocks a receptor on certain defense cells, thus preventing a derailed immune response.

Plant-based seafood alternatives should have similar flavors, textures and nutritional content to the foods they mimic. And recreating the properties of fried calamari rings, which have a neutral flavor and a firm, chewy texture after being cooked, has been a challenge. Building off previous research, a team describes successfully using plant-based ingredients to mimic calamari that matches the real seafood's characteristic softness and elasticity.

We know exercise is good for our body, but what about our brains? A new study suggests that exercise plays a crucial role in keeping our minds sharp, even when one of the brain's key energy sources isn't available. The study offers fresh insight into brain health and suggests that exercise could play a bigger role in preventing cognitive decline than previously thought.

Female bonobos team up to suppress male aggression against them -- the first evidence of animals deploying this strategy. In 85% of observed coalitions, females collectively targeted males, forcing them into submission and shaping the group's dominance hierarchy. This is the first study to test drivers of female dominance in wild bonobos. The study examined 30 years of demographic and behavioral data across six wild bonobo communities. The study suggests that power isn't solely determined by physical strength. It can be driven by social intelligence and coalition-building by females.

A 113-million-year-old hell ant that once lived in northeastern Brazil is now the oldest ant specimen known to science, finds a new report. The hell ant, which was preserved in limestone, is a member of Haidomyrmecinae -- an extinct subfamily that only lived during the Cretaceous period. These ants had highly specialized, scythe-like jaws that they likely used to pin or impale prey.

The global burden of chronic kidney disease (CKD) is rising, with more than 800 million people affected worldwide. Vascular diseases in patients with CKD are unique and grouped as uremic vascular diseases. One of them, calciphylaxis, typically affects patients with end-stage, advanced kidney disease. It is a condition characterized by severe, painful and non-healing skin ulcers with no known cure. Researchers have now discovered a novel biological pathway, called the IL6 pathway, central to the skin lesion initiation and progression. Blocking this pathway they believe, will likely prevent progression of the skin ulcers and resolve the pain seen in patients with calciphylaxis.

Over the past two decades, satellite-based planetary observations have recorded rapid mass loss of Patagonian glaciers, contributing approximately 0.07 mm per year to global sea-level rise. A study links this mass loss to a poleward shift of subtropical high-pressure systems. This large-scale atmospheric circulation change brings more warm air to Patagonia, thereby accelerating glacier melt.
