Many insects will eat almost anything in their sight, such as certain beetles, grasshoppers and locusts, while others are remarkably picky eaters. For example, numerous insect herbivores will feed only on a single plant family ...

Citizen science data from the popular platform iNaturalist has helped uncover the evolution of parental guarding behavior in harvestmen spiders, as shown in research published in the Zoological Journal of the Linnean Society.

One of the most fascinating aspects of physics is that nature often behaves in ways that seem completely counterintuitive. A good example comes from ultrathin materials. If I take a sheet of material and make it thinner ...

A method to interpret artificial intelligence (AI) models used in materials discovery by analyzing their learned features has been developed by researchers from Japan. The method extracts key features from an AI model trained ...

Steel and metal production are among the largest contributors to global greenhouse gas emissions, accounting for approximately 10% of global CO2 emissions. At the same time, modern technology relies on tailored steels and ...

Few animals put on a show quite like manakins. In the rainforests of Central and South America, males of these small tropical birds, with strikingly bright plumage, often gather at communal display sites (leks), where they ...

In a first, a large, international team led by multiple labs at Harvard Medical School and Princeton University has published a complete wiring diagram of all the connections between neurons in the central nervous system ...

Scaffolded DNA and RNA origami is a technique that allows scientists to build tiny, highly precise two- and three-dimensional objects. Because these nanostructures can interact naturally with biological systems, they could ...

Archaeological evidence from the Canary Islands suggests that by the 11th century, people there were harvesting and processing a variety of fish and other marine organisms—indicating that coastal resources may have played ...

Researchers at the UCLA Samueli School of Engineering and CNSI (California NanoSystems Institute), led by Professor Aydogan Ozcan, introduced a snapshot 3D image projection system that integrates a digital encoder with a ...

A new study reveals that, for the first time, areas of Canada's boreal peatlands damaged by oil and gas exploration have failed to recover as scientists and companies predicted and instead have led to a tripling of methane ...

Using data from NASA's Chandra X-ray Observatory, astronomers may have found a supernova remnant in an intriguing neighborhood in the middle of our galaxy. A paper describing these new findings was published in The Astrophysical ...
