Michigan State University researchers have designed robots that, in the future, could be ocean-going and cooperatively track moving targets underwater. Schools of swimming robots would be able to work together to do things that one could not do alone, such as tracking large herds of animals or mapping expanses of pollution that can grow and change shape.

Princeton University researchers have come up with a new twist on the mysterious visual phenomenon experienced by humans known as the "uncanny valley." That twist is that monkeys experience the same exact feeling. The uncanny valley describes that disquieting feeling that occurs when viewers look at representations designed to be as human-like as possible.

Longer toes and a unique ankle structure provide some sprinters with the burst of acceleration that separates them from other runners, according to biomechanists at Penn State University.

A new analysis of climate risk, published by researchers at MIT and elsewhere, shows that even moderate carbon-reduction policies now can substantially lower the risk of future climate change. It also shows that quick, global emissions reductions would be required in order to provide a good chance of avoiding a temperature increase of more than 2 degrees Celsius above the pre-industrial level.

Plants may not have eyes and ears, but they can recognize their siblings, and researchers at the University of Delaware have discovered how. Plants recognize family members by detecting chemical cues secreted by their roots. The finding not only sheds light on the intriguing chemical sensing system in plants, but also may have implications for agriculture and even home gardening.

A new computer algorithm developed at the University of Washington uses hundreds of thousands of tourist photos to automatically reconstruct entire cities in about a day. The tool harnesses the increasingly large digital photo collections available on photo-sharing Web sites such as Flickr.

A new study done by researchers at the University of Massachusetts found that when a TV is on in a room both the quantity and the quality of the interactions between parents and their children drops. The researchers studied about 50 1-, 2-, and 3-year-olds, each of whom was placed with one of their parents in two half-hour sessions.

An international team of scientists has for the first time thoroughly described Ardipithecus ramidus, a hominid species that lived 4.4 million years ago in what is now Ethiopia. The female skeleton, nicknamed Ardi, is 4.4 million years old, 1.2 million years older than the skeleton of Lucy.

A team of researchers in Denmark, at the University of California, Davis, and at UC Berkeley have identified a group of plant proteins that "shut the door" on bacteria that would otherwise infect the plant's leaves. The findings provide a better understanding of plants' immune systems and will likely find application in better protecting crops and horticultural plants against diseases.

Researchers at the Massachusetts Institute of Technology say you're more likely to scan a room, jumping from object to object as you search for something. In addition, the timing of these jumps appears to be determined by waves of activity in the brain that act as a clock.

University of Utah mathematicians have developed a brand new cloaking method that functions through wave cancellation and could someday shield submarines from sonar, planes from radar, buildings from earthquakes, and coastal structures from tsunamis. Most previous research used interior cloaking, where the cloaking device envelops the cloaked object. Researchers say this new method "is the first active, exterior cloaking" technique.

Stanford engineers and others have created a structural design that lets buildings rock during earthquakes, then correct themselves when the shaking stops, confining damage to replaceable steel "fuses."

A Northwestern University study is the first of its kind and demostrates that having musical training can help a listener distinguish between background noise and sound that the listener is meant to hear.

Oregon State University researchers are pioneering the concept of "rich interaction" -- computers that do, in fact, want to communicate with, learn from, and get to know you better as a person.

University of Illinois researchers report that they have assembled a new cancer drug delivery system that, in a cell culture, is able kill tumor cells and spare healthy cells.

An international team of researchers deduced that early modern humans living on the coast of the southern tip of Africa used fire to increase the quality and the effectiveness of their stone tools.

Scientists found that highly managed fisheries caused 10 large troubled fish stocks to grow over the course of the study.

Reseachers at the University of Michigan are using sound waves to push sample fluids through tiny detectors that are only millimeters or centimeters in size.

Using nanodiamonds, researchers at Northwestern University have deomonstrated a method for delivering and releasing curative medicines to a specific location in the body.

A team of computer scientists at the University of Washington developed a prototype system called Vanish that can place a time limit on information uploaded to the internet that causes all the information to become useless when the time is up.

Chemists at Stanford University have created new algorithms that use the computer technology behind today's video game systems to rapidly calculate and depict the structure of molecules.

A University of Utah study shows that brain signals controlling arm movements can be detected accurately using new microelectrodes that sit on the brain but don't penetrate it.

A new study out of Harvard and the University of Virginia finds that you are more likely to know what will make you happy if you ask a total stranger. Another person's experiences are often more informative than your own best guess.

The threat of climate change can still be greatly diminished if nations cut their greenhouse gas emissions by 70 percent during this century. Global temperatures would still rise, but events like sea-level rise might be partially avoided.

A Caltech biologist and his research team have indentified how the antennea of fruit flies process the feeling of wind and then how the flies respond by standing completely still.

Researchers at Cornell University and the University of Melbourne, Australia, are fabricating organic semiconducting materials from a gentle solvent called Supercritical Carbon Dioxide.
