Sounds produced by human activities -- anthropogenic sounds -- account for more than 90% of the underwater soundscape in major freshwater habitats of New England.

Researchers discuss the idea that bacteria, viruses or other infectious pathogens may play a role in Alzheimer's disease.

Biological engineers have created a multitissue model that lets them study the relationships between different organs and the immune system on a microfluidic chip seeded with human cells. With this 'organs-on-a-chip' model, they could explore the role of immune cells in ulcerative colitis and other inflammatory diseases.

A team of researchers have published new calculations that predict a striking and intricate substructure within black hole images from extreme gravitational light bending.

Infants from rural families tend to display negative emotions such as anger and frustration more frequently than their urban counterparts, according to a recent study. Babies born in big cities, on the other hand, typically are less fussy and not as bothered by limits set by their caregivers.

Researchers have designed a new camera that could allow hypertelescopes to image multiple stars at once. The enhanced telescope design holds the potential to obtain extremely high-resolution images of objects outside our solar system, such as planets, pulsars, globular clusters and distant galaxies.

Ion channels, which allow potassium and sodium ions to flow in and out of cells, are crucial in neuronal 'firing' in the central nervous system and for brain and heart function. These channels use a ''ball-and-chain'' mechanism to help regulate their ion flow, according to a new study.

Researchers created a new approach to VR that will allow multiple players to interact with the same VR app on smartphones and provide new opportunities for education, health care and entertainment.

A topic of considerable interest to paleontologists is how dinosaur-dominated ecosystems were structured, how dinosaurs and co-occurring animals were distributed across the landscape, how they interacted with one another, and how these systems compared to ecosystems today.

The first data collected on the diving behavior of reef manta rays in New Caledonia considerably extend the known depth range for this vulnerable species in decline, according to a new study.

There may be many overlooked organic and inorganic materials that could be used to harness sunlight underwater and efficiently power autonomous submersible vehicles, report researchers. New research develops guidelines for optimal band gap values at a range of watery depths, demonstrating that various wide-band gap semiconductors, rather than the narrow-band semiconductors used in traditional...

A world-first study using sophisticated genetic analysis techniques have found that some fish are better than others at coping with heatwaves. The study tracks wild fish populations during a severe marine heatwave that killed a third of the Great Barrier Reef corals.

The oldest fossil of a modern bird yet found, dating from the age of dinosaurs, has been identified by an international team of palaeontologists.

Analysis shows global warming is intensifying the occurrence of unprecedented hot spells and downpours faster than predicted by historical trends.

Two new species of sawsharks discovered in the West Indian Ocean reinforces how much we still don't know about life in the ocean and the impact climate change is having on it.

A puzzling modification of DNA that is typical in bacteria does not occur in humans or other mammals. This has been shown in a new study. The study shows that findings from the epigenetic marker 6mdA in animals are probably the result of limitations in technology and bacterial contamination of samples.

A new type of robot combines traditional and soft robotics, making it safe but sturdy. Once inflated, it can change shape and move without being attached to a source of energy or air.

A recent study in mice led a team of researchers in Japan to believe that psychosis may be caused by problems with specialized nerve cells deep within the brain, as well as a certain kind of learning behavior. The researchers hope this could provide insight into the emergence of delusions in patients with psychosis or schizophrenia with the aim of finding ways to help them.

Researchers found that farms with diverse crops planted together provide more secure, stable habitats for wildlife and are more resilient to climate change than the single-crop standard that dominates today's agriculture industry.

Brownian motion describes the random movement of particles in fluids, however, this revolutionary model only works when a fluid is static, or at equilibrium. In real-life, fluids often contain particles that move by themselves, which can cause stirring in the fluid, driving it away from equilibrium. Now researchers have presented a novel theory to explain observed particle movements in these...

With the help of photolithography and programmable DNA, researchers have created a new technique that can rapidly 'print' two-dimensional arrays of cells and proteins that mimic a wide variety of cellular environments in the body. This technique could help scientists develop a better understanding of the complex cell-to-cell messaging that dictates a cell's final fate.

Supercomputer simulations support a new mechanism for the budding off of viruses like the coronavirus. ESCRTIII polymer features clear intrinsic twist in molecular dynamics simulations, might play major role in creating three-dimensional buckling of the cell membrane. Related study used simulations to find mechanism for DNA base addition during replication.

The identification of an insect-specific metal-sensing receptor in the gut lining highlights a possible new way to curb populations of disease-transmitting insects such as mosquitoes.

Like a snapshot, amber preserves bygone worlds. Paleontologists have now described four new beetle species in fossilized tree resin from Myanmar, which belong to the Kateretidae family. As well as the about 99 million years old insects, the amber also includes pollen. It seems that the beetles helped the flowering plants to victory, because they contributed to their propagation.
