Sounds produced by human activities—anthropogenic sounds—account for more than 90 percent of the underwater soundscape in major freshwater habitats of New England. Rodney Rountree of The Fish Listener in Massachusetts, and Adjunct Associate Professor at the University of Victoria, and colleagues present these findings in the open-access journal PLOS ONE on March 18, 2020.

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.

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.

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.

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.

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.

Maggots on a dead body or wound can help pinpoint when a person or animal died, or when maltreatment began in elder, child care or animal neglect cases. However, the current process for making this determination is time consuming and resource intensive. It also relies on species assessment by trained entomologists. Now, researchers report the development of a molecular maggot analysis method that's quick, easy and less subjective.

Citrus greening, also called Huanglongbing (HLB), is devastating the citrus industry. Florida alone has experienced a 50 to 75 percent reduction in citrus production. There are no resistant varieties of citrus available and limited disease control measures.

Not one, but TWO new species of the rarely seen six-gilled sawsharks have been found in the West Indian Ocean by an international team of marine scientists.

In a sampling of fish from a creek that flows into San Diego Bay, nearly a quarter contain microplastics, according to a new study published in the journal PLOS ONE. The study, which examined plastics in coastal sediments and three species of fish, showed that the frequency and types of plastic ingested varied with fish species and, in some cases, size or age of fish.

It isn't easy being a loner—someone who resists the pull of the crowd, who marches to their own drummer.

Like humans, cells can be easily influenced by peer pressure.

A puzzling modification of DNA that is common in bacteria is not present in humans or other mammals. This has been shown in a new study by scientists at Linköping University in Sweden, published in Science Advances. The study shows that detection of the epigenetic mark 6mdA in animals was probably the result of limitations of the technology used and bacterial contamination of samples.

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 study published March 18 in the open-access journal PLOS ONE by Hugo Lassauce of the University of New Caledonia, and colleagues. These results add new information on the habitat use of the species in a region where manta behavior has not previously been studied, and increase their known depth range by more than 200 m.

In 2016, ocean temperatures soared, devastating the corals of Australia's Great Barrier Reef. As the frequency, duration and magnitude of these marine heatwaves increases due to human-induced climate change, scientists have yet to fully grasp the physiological, behavioral, and long-term consequences for wild fish populations.

In the neotropical forest of Barro Colorado Island in Panama, an unusual bee hatched: half male and half female. The Smithsonian Tropical Research Institute students and scientists working on nocturnal, socially flexible Megalopta bees at BCI recognized it as a gynandromorph: a rare condition that results in the expression of both male and female characteristics.

Early on in each cell, a critical protein known as FoxA2 simultaneously binds to both the chromosomal proteins and the DNA, opening the flood gates for gene activation, according to a new study led by researchers in the Perelman School of Medicine at the University of Pennsylvania. The discovery, published in Nature Genetics, helps untangle mysteries of how embryonic stem cells develop into organs.

Fundamental research supported by supercomputers could help lead to new strategies and better technology that combats infectious and genetic diseases.

A study that "dissected" 3,100 pieces of coyote poop discovered domestic cats are a big part of what urban coyotes eat for breakfast, lunch and dinner, according to the National Park Service.

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.

An ancient Elpistostege fish fossil found in Miguasha, Canada has revealed new insights into how the human hand evolved from fish fins.

Current molecular biochemistry, microscopy and genetic techniques have become so powerful that scientists can now make mechanistic discoveries—supported by multiple lines of evidence—about intimate processes in plant reproduction that once were very difficult to examine, says molecular biologist Alice Cheung at the University of Massachusetts Amherst.

How we farm can guard against climate change and protect critical wildlife—but only if we leave single-crop farms in the dust, according to a new Stanford study.
