In a study published today in Science Advances, researchers from the Ocean Discovery League reveal that only a minuscule fraction of the deep seafloor has been imaged. Despite covering 66% of Earth's surface, the deep ocean remains largely unexplored.

Heriot-Watt scientists have discovered giant underwater mud waves buried deep below the Atlantic Ocean, 400 kilometers off the coast of Guinea-Bissau in west Africa.

Parental care might help invasive brown widow spiders spread. Valeria Arabesky and colleagues at Ben-Gurion University of the Negev found that invasive brown widow spiders effectively defend their egg sacs against wasp parasites. The spiders use multiple defense strategies, including guarding behaviors and constructing their egg sacs with denser spikes when wasps are around. These strategies may benefit the invasive species and protect the spiders against high levels of predation and parasitism.

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.
