Phys.org / Even morphologically similar pollinators carry distinct pollen assemblages
The body size, morphology and associated behavioral traits of flower-visiting insects strongly influence the quantity of pollen they transport. Thus, pollinators with similar appearances are often assumed to exert similar ...
Phys.org / Third time's the charm for a row of faint galaxies without dark matter
A Yale-led team of astronomers has found a third galaxy devoid of dark matter—located alongside the other two in a formation that has never been seen before. Astronomers have followed a faint, cosmic trail of gas to a third ...
Phys.org / Cockatoos learn when touchscreen rewards 'die,' then apply rule to new contexts
For humans, death is surrounded by culture, emotion, ritual and language. But the question can be framed in a much more basic way: What would an animal have to understand in order to recognize that someone has died?
Phys.org / When glaciers vanish, so does the hidden life they support
We often hear about glacier melting and predictions of what climate change could do. But very little is mentioned about the effects on ecosystems or the animals that call them home. To redress some of this imbalance, an international ...
Phys.org / RNA barcoding approach reveals previously unknown virus–host relationships
An interdisciplinary team of Rice University researchers has uncovered previously unknown relationships between bacteriophages—viruses that infect bacteria—and their bacterial hosts, offering a powerful new tool for next-generation ...
Medical Xpress / Language-based AI model spots early heart disease in ECGs, reaching 94.2% accuracy
A machine-learning model based on Transformer architecture, a form of artificial intelligence originally developed for language processing, can be used to detect heart disease from electrocardiograms (ECGs), according to ...
Phys.org / Indian millets contain distinct lipid fingerprints with anti-diabetic and anti-inflammatory potential
Indian millets are a staple for the country's population of more than a billion. They are also gaining global popularity, with rising exports and a reputation as a climate-resilient crop. Now, new research shows that their ...
Phys.org / Physicists identify upper limit to resistivity in a pure metal
Experimental atomic physicists have discovered there is a maximum amount of electrical resistance, or resistivity, that can result from collisions between electrons.
Phys.org / A flexible graphene-based neural interface can 'speak and listen' to the brain
Neural interfaces are devices that can detect or modulate neuronal activity when placed in contact with the brain. They are already used to treat various conditions related to the nervous system. However, current technologies ...
Phys.org / Random deformation lets glassy materials store precise mechanical memories, simulations reveal
Amorphous materials such as glass are solids whose internal structure lacks a repeating pattern. Their molecules are arranged in a random and irregular way. Surprisingly, these disordered materials can "remember" past mechanical ...
Phys.org / Why one famous predator shrank two ways: Fossils reveal distinct growth strategies in early Permian Dimetrodon
The sail-backed predator Dimetrodon is one of the most iconic animals of the early Permian—long before dinosaurs dominated Earth. Most known species of this early relative of mammals reached large body sizes, sometimes up ...
Dialog / Finding where breast cancer has spread: AI scans medical records to spot metastatic disease
One of the first things I noticed while working with oncology data at Mayo Clinic was how difficult it can be to answer what seems like a simple question: Where did a patient's cancer spread?
