Robotic proxy brings remote users to life in real time      (via sciencedaily.com)     Original source 

Researchers have developed a robot, called ReMotion, that occupies physical space on a remote user's behalf, automatically mirroring the user's movements in real time and conveying key body language that is lost in standard virtual environments.

Hammerhead sharks hold their breath on deep water hunts to stay warm      (via sciencedaily.com)     Original source 

Scalloped hammerhead sharks hold their breath to keep their bodies warm during deep dives into cold water where they hunt prey such as deep sea squids. This discovery provides important new insights into the physiology and ecology of a species that serves as an important link between the deep and shallow water habitats.

Earth's first animals had particular taste in real estate      (via sciencedaily.com)     Original source 

Even without body parts that allowed for movement, new research shows -- for the first time -- that some of Earth's earliest animals managed to be picky about where they lived.

Researchers discover a cause of rapid ice melting in Greenland      (via sciencedaily.com)     Original source 

While conducting a study of Petermann Glacier in northwest Greenland, researchers uncovered a previously unseen way in which the ice and ocean interact. The glaciologists said their findings could mean that the climate community has been vastly underestimating the magnitude of future sea level rise caused by polar ice deterioration.

Plastic can drift far away from its starting point as it sinks into the sea      (via sciencedaily.com)     Original source 

Discarded or drifting in the ocean, plastic debris can accumulate on the water's surface, forming floating islands of garbage. Although it's harder to spot, researchers suspect a significant amount also sinks. In a new study in ACS' Environmental Science & Technology, one team used computer modeling to study how far bits of lightweight plastic travel when falling into the Mediterranean Sea. Their results suggest these particles can drift farther underwater than previously thought.

First observational evidence of beaufort gyre stabilization, which could be precursor to huge freshwater release      (via sciencedaily.com)     Original source 

A new study provides the first observational evidence of the stabilization of the anti-cyclonic Beaufort Gyre, which is the dominant circulation of the Canada Basin and the largest freshwater reservoir in the Arctic Ocean.

Scurrying centipedes inspire many-legged robots that can traverse difficult landscapes      (via sciencedaily.com)     Original source 

Intrigued to see if the many limbs could be helpful for locomotion in this world, a team of physicists, engineers, and mathematicians are using this style of movement to their advantage. They developed a new theory of multilegged locomotion and created many-legged robotic models, discovering the robot with redundant legs could move across uneven surfaces without any additional sensing or control technology as the theory predicted.

AI could run a million microbial experiments per year      (via sciencedaily.com)     Original source 

Automation uncovers combinations of amino acids that feed two bacterial species and could tell us much more about the 90% of bacteria that humans have hardly studied. An artificial intelligence system enables robots to conduct autonomous scientific experiments -- as many as 10,000 per day -- potentially driving a drastic leap forward in the pace of discovery in areas from medicine to agriculture to environmental science.

Indo-Pacific corals more resilient to climate change than Atlantic corals      (via sciencedaily.com)     Original source 

In the face of global warming and other environmental changes, corals in the Atlantic Ocean have declined precipitously in recent years, while corals in the Pacific and Indian Oceans are faring better. By describing several species of symbiotic algae that these corals need to grow, an international team has found that these mutualistic relationships from the Indo-Pacific may be more flexible and ultimately resilient to higher ocean temperatures than those in the Atlantic.

A touch-responsive fabric armband -- for flexible keyboards, wearable sketchpads      (via sciencedaily.com)     Original source 

It's time to roll up your sleeves for the next advance in wearable technology -- a fabric armband that's actually a touch pad. Researchers say they have devised a way to make playing video games, sketching cartoons and signing documents easier. Their proof-of-concept silk armband turns a person's forearm into a keyboard or sketchpad. The three-layer, touch-responsive material interprets what a user draws or types and converts it into images on a computer.

West Antarctic Ice Sheet retreated far inland, re-advanced since last Ice Age      (via sciencedaily.com)     Original source 

The West Antarctic Ice Sheet is melting rapidly, raising concerns it could cross a tipping point of irreversible retreat in the next few decades if global temperatures rise 1.5 to 2.0 degrees Celsius (2.7 to 3.8 degrees Fahrenheit) above preindustrial levels. New research finds that 6,000 years ago, the grounded edge of the ice sheet may have been as far as 250 kilometers (160 miles) inland from its current location, suggesting the ice retreated deep into the continent after the end of the last ice age and re-advanced before modern retreat began.

Highly dexterous robot hand can operate in the dark -- just like us      (via sciencedaily.com)     Original source 

Researchers demonstrated a highly dexterous robot hand, one that combines an advanced sense of touch with motor learning algorithms in order to achieve a high level of dexterity. In addition, the hand worked without any external cameras -- it's immune to lighting, occlusion, or similar issues. Because the hand doesn't rely on vision to manipulate objects, it can do so in difficult lighting conditions that would confuse vision-based algorithms -- it even operates in the dark.

The future is foggy for Arctic shipping      (via sciencedaily.com)     Original source 

As the Arctic warms and loses sea ice, trans-Arctic shipping has increased, reducing travel time and costs for international trade. However, a new study finds that the Arctic Ocean is getting foggier as ice disappears, reducing visibility and causing costly delays as ships slow to avoid hitting dangerous sea ice.

Male California sea lions are becoming bigger and better fighters as their population rebounds      (via sciencedaily.com)     Original source 

California sea lions have managed to maintain -- and, in the case of males, increase -- their average body size as their population grows and competition for food becomes fiercer. This is in contrast to other marine mammals, whose average body size tends to decrease as their numbers increase. Researchers report that sexual selection was a strong driving force for males to grow bigger and to strengthen muscles in their neck and jaw that help them fight for mates. Both male and female sea lions evaded food shortages by diversifying their diets and, in some cases, foraging further from the shore.
