Fish generate movable pairs of vortices to propel them forward like body waves
Swimming in complex underwater environments, fish are unmatched when it comes to motion control and flexibility. For decades, researchers have been inspired to copy nature's most gifted swimmers to optimize underwater vehicle propulsion and maneuvera.....»»
Australian courts use "body language" to judge witness credibility
Nonverbal behavior in the courtroom can significantly influence how judges assess the credibility of witnesses in their rulings. But is reliance on "body language" based on sound science?.....»»
Google CEO says over 25% of new Google code is generated by AI

Study models dinoflagellate light in breaking waves
A new study led by Scripps Institution of Oceanography demonstrates, for the first time, how scientists can use computer simulations to quantify the light emitted by dinoflagellates when they flash in breaking waves and create stunning displays of bi.....»»
Researchers show nanoplastics can reduce the effectiveness of antibiotics
In a recent study, an international research team with significant involvement from MedUni Vienna has investigated how nanoplastic particles deposited in the body affect the effectiveness of antibiotics......»»
Compact in-incubator imaging device allows real-time remote monitoring of cell growth
Unlike most cells in the human body, stem cells have the unique ability to divide indefinitely. This property makes them especially appealing to scientists exploring ways to extend human lifespans or develop new methods for repairing damaged tissues......»»
Taiwan battens down for Super Typhoon Kong-rey
Five-meter waves pounded Taiwan's shores Wednesday as Super Typhoon Kong-rey drew near, with forecasters expecting the storm to strengthen before hitting the island as one of the most powerful in years......»»
How harmful are microplastics to human health?
Microplastics have been found throughout the human body -- including inside lungs, blood and brains -- and while it is not yet clear how harmful they are to our health, some researchers are sounding the alarm......»»
Oceanographers record the largest predation event ever observed in the ocean
There is power in numbers, or so the saying goes. But in the ocean, scientists are finding that fish that group together don't necessarily survive together. In some cases, the more fish there are, the larger a target they make for predators......»»
From fish to clean water, the ocean matters—how to quantify the benefits
Nature protection, conservation and restoration is "not a trivial matter but key to human survival," according to scientists quoted in a 2005 UN report. To demonstrate this, they developed the concept of "ecosystem services"—the benefits that peopl.....»»
Are we drowning out the sounds of the sea?
The sound of waves gently crashing is one of the most relaxing noises. But beneath the surface, things are far less peaceful......»»
Celebrating Spooky Lake Month with Its Creator Geo Rutherford
An open body of water can be particularly eerie. It’s part of what led creator and author Geo Rutherford to make her viral videos on Spooky Lakes......»»
Red-cockaded woodpeckers" recovery in southeast leads to status change from endangered to threatened
The red-cockaded woodpecker, an iconic bird in southeastern forests, has recovered enough of its population to be downlisted from an endangered species to a threatened one, the U.S. Fish and Wildlife Service announced Thursday......»»
Study shows invasive silver carp reduce movement in Chicago-area water
Invasive silver carp have been spreading throughout the Mississippi River Basin since their introduction a half-century ago. Yet, try as they might, the fish have not advanced beyond a particular stretch of the Illinois River north of Kankakee. Resea.....»»
"Well-man" thrown from castle identified from 800-year-old Norse saga
A passage in the Norse "Sverris Saga," the 800-year-old story of King Sverre Sigurdsson, describes a military raid that occurred in AD 1197, during which a body was thrown into a well at Sverresborg Castle, outside Trondheim in central Norway, likely.....»»
Research on how gut bacteria breaks down dietary fiber could lead to helpful new probiotics
There are trillions of bacteria in the human gut microbiome. When we eat fruits and vegetables, some of these bacteria break down the dietary fiber and provide us with metabolites, small molecules our body can use for energy or cell repair......»»
Warming lakes and rivers may spread fish pathogens
Michigan's rivers and lakes were once cold enough that fish were protected from some infection-causing parasites. As the Great Lakes ecosystem warms, a Michigan State University researcher is investigating new pathogens that may become relevant to th.....»»
Teachers try a different preschool curriculum to prevent youth crime—checking in 20 years later, it worked
There's been an increased political and media focus recently on so-called youth crime waves, particularly in Queensland and the Northern Territory......»»

What do the ginkgo (a tree), the nautilus (a mollusk) and the coelacanth (a fish) all have in common?.....»»
River flow responses to heat waves may change more rapidly under climate change, research finds
A pair of studies by researchers in Simon Fraser University's School of Environmental Science examine how climate change could alter the way Canadian rivers respond to extreme heat events......»»
"Paleo-robots" provide an experimental approach for understanding how fish started to walk on land
The transition from water to land is one of the most significant events in the history of life on Earth. Now, a team of roboticists, paleontologists and biologists is using robots to study how the ancestors of modern land animals transitioned from sw.....»»
