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.....»»
Polar bears are sustaining ice-related paw injuries in a warming Arctic
Polar bears in some parts of the high Arctic are developing ice buildup and related injuries to their feet, apparently due to changing sea ice conditions in a warming Arctic. While surveying the health of two polar bear populations, researchers found.....»»
AI, as it stands today, is a valuable tool for the auto industry but a poor substitute for humans
As the industry experiments with artificial intelligence, business owners need to be aware of the technology's promise and its limitations......»»
The case of a robot shark in a marine park raises questions about animal welfare
After five years of renovation, Shenzhen's Xiaomeisha Sea World finally opened its doors to the public. But the marine park soon found itself the object of international discussion as it was revealed their advertised real whale shark was actually a r.....»»
A blueprint for mapping melting ice sheets: Open-source tool can help make radar systems at a fraction of the cost
Researchers in the Stanford Radio Glaciology lab use radio waves to understand rapidly changing ice sheets and their contributions to global sea-level rise. This technique has revealed groundwater beneath Greenland, the long-term impacts of extreme m.....»»
Pilot expeditions work to preserve the white shark in the Mediterranean Sea
The Mediterranean Sea is a paradise. Pristine waters and an incredible coastline spanning multiple continents are renowned the world over. Below those picturesque, and sometimes crowded, waters swims a legendary creature facing a treacherous and unce.....»»
Novel quantum lidar achieves high-sensitivity wind detection
A research team has proposed a wind sensing lidar theory based on up-conversion quantum interference and successfully developed a prototype. Their work is published in ACS Photonics......»»
How Cells Resist the Pressure of the Deep Sea
Cell membranes from comb jellies reveal a new kind of adaptation to the deep sea: curvy lipids that conform to an ideal shape under pressure......»»
Scientists find southern killer whales of the Pacific have access to enough food, deepening mystery of their struggles
A pair of marine mammal scientists at The University of British Columbia, has found that claims that a lack of access to salmon is what is driving the crash in population numbers for southern resident killer whales of the Pacific are wrong......»»
Ocean eddy currents funnel extreme heat and cold to the life-filled depths
On land, we're familiar with heat waves and cold snaps. But the deep sea also experiences prolonged periods of hot and cold......»»
Work is underway on 2 Lord of the Rings live-action projects, including The Hunt for Gollum
The Hunt for Gollum is just one of the live-action Lord of the Rings movies that may be coming soon......»»
Saturday Citations: Brown dwarf actually brown dwarfs; the adaptability of ice-age humans; archaeologists excited
This week, researchers discovered a near-Earth microquasar that sheds new light on sources of relativistic outflows. Doctors reported finding a triphallic gentleman. And neuroscientists reported on modest cognitive boosts from short (or "acute," in c.....»»
Bizarre fish has sensory “legs” it uses for walking and tasting
Some sea robin species can use their legs to sense prey. Evolution has turned out bizarre and baffling creatures, such as walking fish. It only gets weirder from there. Some of th.....»»
Team develops promising new form of antibiotic that makes bacterial cells self-destruct
To address the global threat of antibiotic resistance, scientists are on the hunt for new ways to sneak past a bacterial cell's defense system. Taking what they learned from a previous study on cancer, researchers from the University of Toronto (U of.....»»
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......»»
