Sensor Gives Robot Greater Dexterity

September 22, 2014 7:00 am | by MIT, Larry Hardesty Videos Comments

Researchers have equipped a robot with a novel tactile sensor that lets it grasp a USB cable draped freely over a hook and insert it into a USB port. The sensor is small enough to fit on a robot’s gripper and its processing algorithm is fast, so it can give the robot feedback in real time.

Dogs Can Be Pessimists

September 19, 2014 7:00 am | by Univ. of Sydney Videos Comments

Dogs generally seem to be cheerful, happy-go-lucky characters, so you might expect that they would have an optimistic outlook on life. But, some dogs are distinctly more pessimistic than others.


Materials Mimic Octopuses’ Abilities

September 18, 2014 7:00 am | by MIT, David Chandler Videos Comments

Cephalopods are able to change both the color and texture of their skin within seconds to blend into their surroundings— a capability that engineers have long struggled to duplicate in synthetic materials. Now, a team has come closer than ever to achieving that goal, creating a flexible material that can change its color or fluorescence and its texture at the same time, on demand, by remote control.


Microscope Study Helps Cook Juicier Steaks

September 17, 2014 7:00 am | by The Univ. of Melbourne Videos Comments

A new study into meat tenderness could refine the way people cook steak. Researchers conducted studies using microscopes to see what happens to meat cells while being cooked. They found that meat shrinks while cooking not once but twice.


Chemistry of a Smartphone

By now, we've got all the details about Apple's latest iPhone. But what do you really know about the guts of the iPhone 6, or any smartphone for that matter?


Cheetah Robot Can Run, Jump, Untethered, Across Grass

September 16, 2014 7:00 am | by MIT, Jennifer Chu Videos Comments

Researchers have developed an algorithm for bounding that they’ve successfully implemented in a robotic cheetah— a sleek, four-legged assemblage of gears, batteries and electric motors that weighs about as much as its feline counterpart. The team recently took the robot for a test run where it bounded across grass at a steady clip.


Wrinkles in Rock May Be Signs of Early Life

September 15, 2014 7:00 am | by MIT, Jennifer Chu Videos Comments

Researchers have identified a mechanism by which wrinkles may have formed in ancient rocks. Based on this mechanism, they posit that such fossilized features may be a vestige of microbial presence— in other words, where there are wrinkles, there must have been life.

Understanding Physics of Fire Imperative for Space Safety

September 12, 2014 7:00 am | by NASA Videos Comments

Astronauts are studying how fires burn in microgravity and how to put them out. It's a basic safety issue: if a fire ever breaks out onboard a spacecraft, astronauts need to be able to control it.


Sharks May Not Smell Food in Acidic Water

September 11, 2014 7:00 am | by Georgia Institute of Technology Videos Comments

The increasing acidification of ocean waters caused by rising atmospheric CO2 levels could rob sharks of their ability to sense the smell of food, a new study suggests. Elevated CO2 levels impaired the odor-tracking behavior of the smooth dogfish, a shark whose range includes the Atlantic Ocean off the eastern U.S.


Algorithm Can Help Clean up Space

September 10, 2014 2:00 pm | by MIT, Larry Hardesty Videos Comments

An algorithm, tested aboard the International Space Station, analyzes the rotation of objects in space. Understanding how objects are spinning, where their centers of mass are and how their mass is distributed is crucial to any number of actual or potential space missions, from cleaning up debris in the geosynchronous orbit favored by communications satellites to landing a demolition crew on a comet.


Chemistry Provides Life Hacks

Bees’ Bacteria May Replace Antibiotics

September 9, 2014 7:00 am | by Lund Univ. Videos Comments

Raw honey has been used against infections for millennia. So what is the key to its’ antimicrobial properties? Researchers have identified a unique group of 13 lactic acid bacteria found in fresh honey, from the honey stomach of bees. The bacteria produce a myriad of active antimicrobial compounds.


Material Changes Color as Glucose Levels Fluctuate
