The best jaw for hunting fast fish is long and full of sharp teeth. This makes sense to us, but it also makes sense in nature: New fossil evidence from Virginia Tech geoscientists revealed that different species of predatory fish independently evolved similar jaw structures hundreds of millions of years apart.

To be talked about or to be ignored, which is better? It's not a Shakespearean question, but one that a research team led by a University of Mississippi professor wanted to answer.

Northwestern Medicine investigators have developed first-of-its-kind eyedrops that use synthetic nanoparticles to help the eye regenerate cells that have been damaged by mustard keratopathy, or exposure to mustard gas, and other inflammatory eye diseases, detailed in a recent study published in the journal npj Regenerative Medicine.

Researchers have shed new light on how the environment promotes the generation of new species. A study led by Dr. Benjamin Jarrett from Bangor University looked at what happens when two populations of the same species are evolving in different environments. It asks if they are more or less likely to interbreed than populations evolving in the same environment.

A team of researchers from Rice University, Carnegie Mellon University and other leading global institutions has outlined a bold new roadmap for harnessing heterogeneous catalysis to destroy per- and polyfluoroalkyl substances (PFAS), the so-called "forever chemicals" that have contaminated water supplies worldwide.

A first-of-its-kind study by researchers at Michigan State University reveals that individuals who experience the most distress and impairment in daily functioning from social media use are more likely to believe fake news.

The use of light signals to connect electronic components is a key element of today's data communication technologies, because of the speed and efficiency that only optical devices can guarantee. Photonic integrated circuits, which use photons instead of electrons to encode and transmit information, are found in many computing technologies. Most are currently based on silicon—a good solution because it is already used for electronic circuits, but with a limited bandwidth.

A sweeping 26-country study reveals a consistent gap in trust toward climate scientists based on political ideology, with right-leaning individuals reporting lower trust than their left-leaning counterparts. The divide is especially stark in wealthier democracies and English-speaking nations, according to the research.

It's spring, the birds are migrating and bird flu (H5N1) is rapidly evolving into the possibility of a human pandemic. Researchers from the University of Maryland School of Public Health have published a comprehensive review documenting research on bird flu in cats and calling for urgent surveillance of cats to help avoid human-to-human transmission.

A dangerous hospital superbug has been found to digest plastic—specifically the kind used in some sutures, stents and implants inside the human body. Microbiologists at Brunel University of London show the bacteria can feed on plastic to survive, potentially enabling these pathogens to survive longer in hospital wards and within patients.
