Thanks to humans, Salish Sea waters are too noisy for resident orcas to hunt successfully
The Salish Sea—the inland coastal waters of Washington and British Columbia—is home to two unique populations of fish-eating orcas, the northern resident and the southern resident orcas. Human activity over much of the 20th century, including red.....»»
New strategy unlocks magnetic switching with hydrogen bonding at molecular level
A research team from Kumamoto University has successfully developed a new approach to create switchable magnetic materials by using hydrogen bonding at the molecular level. Their study shows how certain metal complexes, previously unresponsive to ext.....»»
Controlling sound waves with Klein tunneling improves acoustic signal filtration
In the context of sensory modalities, eyes work like tiny antennae, picking up light, electromagnetic waves traveling at blistering speeds. When humans look at the world, their eyes catch these waves and convert them into signals the brain reads as c.....»»
It’s increasingly unlikely that humans will fly around the Moon next year
It's not just Orion's heat shield; the mission's ground systems are running out of time. Don't book your tickets for the launch of NASA's Artemis II mission next year just yet. W.....»»
Incorporating effects of sea spray into models to improve hurricane intensity forecasting
Hurricanes are massive, complex systems that can span hundreds of miles as they swirl around the low pressure of the storm's eye. In such a complicated situation, predicting how powerful a hurricane will grow is a difficult undertaking......»»
Catching prey with grappling hooks and cannons: The unusual weapons arsenal of a predatory marine bacterium
Countless bacteria call the vastness of the oceans home, and they all face the same problem: the nutrients they need to grow and multiply are scarce and unevenly distributed in the waters around them. In some spots they are present in abundance, but.....»»
Insulator-to-metal transition achieved in iridate/manganate heterostructures
A research team has successfully achieved an atomically controlled insulator-to-metal transition in iridate/manganate heterostructures. Their findings were recently published in Nature Communications......»»
Microbiome studies in humans and zoo animals pave the way for new drug development
Microorganisms do not just colonize the body of mammals during infections. Billions of microbes can be found on and in healthy humans and animals at any given time, communicating with each other via chemical signals and thus influencing their health......»»
DNA confirms these 19th-century lions ate humans
“Tsavo Man-Eaters” killed dozens of people in late 1890s, including Kenya-Uganda Railway workers. For several months in 1898, a pair of male lions turned the Tsavo region of K.....»»
How the invasive spiny water flea spread across Canada, and what we can do about it
Across the tranquil waters of Canada's vast network of lakes and rivers, a quiet invader is on the move. The spiny water flea, Bythotrephes cederströmii, is a microscopic predator that is forever altering the ecological fabric of aquatic habitats in.....»»
Humans have near-equal numbers of male and female babies, unlike many other animals—a new genetic study looks for clues
We know that boys and girls are produced in much the same frequency. But how—and why—is this 1:1 ratio achieved?.....»»
Coastal cities have a hidden vulnerability to storm-surge and tidal flooding that"s entirely caused by humans
Centuries ago, estuaries around the world were teeming with birds and turbulent with schools of fish, their marshlands and endless tracts of channels melting into the gray-blue horizon......»»
DNA confirms these 19th century lions ate humans
“Tsavo Man-Eaters” killed dozens of people in late 1890s, including Kenya-Uganda Railway workers. For several months in 1898, a pair of male lions turned the Tsavo region of K.....»»
Human Origins Look Ever More Tangled with Gene and Fossil Discoveries
Fossil and gene discoveries paint an ever-more-intertwined history of humans combining with vanished species like Neandertals.....»»
Global temperature analysis reveals deep ocean marine heat waves are underreported
While marine heat waves (MHWs) have been studied at the sea surface for more than a decade, new research published today in Nature has found 80% of MHWs below 100 meters are independent of surface events, highlighting a previously overlooked aspect o.....»»
Genome sequencing could unlock answers to yellow jacket behavior
The most recognizable yellow jacket at Georgia Tech is made of fabric and foam, but Professor Mike Goodisman and a team of researchers revealed a far more complex cellular structure by successfully sequencing the genome of two local species of yellow.....»»
Dutch students warn space mission of noisy white dwarfs
The background noise of gravitational waves from orbiting white dwarf stars will be stronger than the noise from binary black holes. This is what two Dutch master's students and their supervisor predict in two papers in anticipation of the LISA space.....»»
Reports: Tesla’s prototype Optimus robots were controlled by humans
But the prototypes used "artificial intelligence" to control their walking. After Elon Musk provided his "long-term" vision for autonomous, humanoid robots at last week's "We, Rob.....»»
Is the physics of red blood cells in bats a key to "artificial hibernation" for humans?
The mechanical properties of red blood cells (erythrocytes) at various temperatures could play an important role in mammals' ability to hibernate. This is the outcome of a study that compared the thermomechanical properties of erythrocytes in two spe.....»»
Reoxygenating oceans: Startups lead the way in Baltic Sea
European scientists have teamed up with two startups in a pioneering experiment to tackle one of the major problems facing sea life—the depletion of oxygen in the ocean, causing the disappearance of fish and marine biodiversity......»»
How "vaccinating" plants could reduce pesticide use and secure global food supplies
In a growing and changing world, we need to find ways of putting food on everyone's table. Pesticides have enabled mass cultivation on an incredible scale, but they can have harmful secondary effects on humans and wildlife, and pests are rapidly evol.....»»
