 Combined Forces | File Type: audio/mpeg | Duration: 1:30

Cancer cells use tricks to hide from our body's immune system. One trick is to mask their presence in the body. Now, a bioengineer from Yale University has created cell-sized plastic spheres that both prep the immune system to recognize specific diseases and also increase the immune system's fighting force.

 Car Watch | File Type: audio/mpeg | Duration: 1:30

The annoying blare of an ignored car alarm may become a sound of the past if a cooperative, muteable and silent network of monitors proposed by Penn State University researchers is deployed in automobiles and in parking lots.

 Degrees of Survival | File Type: audio/mpeg | Duration: 1:30

University of Washington scientists have found that species living in the tropical centers of the world are likely to face greater peril from global warming than those species located in cooler climates, because their tolerance for temperature increases is much narrower.

 Primal Urges | File Type: audio/mpeg | Duration: 1:30

A mass grave of skeletons in southwestern Germany suggests that neighboring tribes from prehistoric times were prepared to kill their male rivals to secure their women.

 Happy Trails | File Type: audio/mpeg | Duration: 1:30

Americans grow happier as they grow older, according to social science researchers at the University of Chicago, whose 33-year study is one of the most thorough examinations of happiness ever done in America.

 Frogantuan | File Type: audio/mpeg | Duration: 1:30

A team of researchers, led by a Stony Brook University paleontologist, discovered the remains of what may be the largest frog ever to exist. The fossilized remains of this 16-inch, 10-pound ancient frog were found in Madagascar and link a group of frogs that lived 65-70 million years ago with frogs living today in South America.

 Links in E-mail Chain Letters Not Well Connected | File Type: audio/mpeg | Duration: 1:30

It was once thought that e-mail chain letters traveled to internet users in much the same way that disease spreads during an epidemic--people receive a message and then pass it on to those they come in contact with. However, new research from Cornell University and Carleton College suggests that e-mail chain letters travel in a less direct, more diffuse pattern than previously assumed.

 Fragrant Violation | File Type: audio/mpeg | Duration: 1:30

Air pollution from power plants and automobiles is diminishing the fragrance of flowers and thereby inhibiting the ability of pollinating insects to follow scent trails to their source, a new University of Virginia study indicates.

 True Lies | File Type: audio/mpeg | Duration: 1:30

Two researchers at Cornell University argue that children are more likely to tell the truth while under oath in court because their minds depend heavily on remembering what actually occurred, as opposed to adults, whose minds depend heavily on the meaning or interpretation of what occurred.

 Maglev Mouse | File Type: audio/mpeg | Duration: 1:30

Thanks to a touch-based interface developed at Carnegie Mellon University, computers that have long been used as tools in designing and manipulating three-dimensional objects may soon provide people with a way to sense or feel the texture of those same objects.

 Blues Light Special | File Type: audio/mpeg | Duration: 1:30

A team of behavioral scientists from four major U.S. universities found that people who feel sad and self-focused are willing to pay more money for goods than those in neutral states of feeling.

 On A Roll | File Type: audio/mpeg | Duration: 1:30

MIT and University of Rochester researchers report important advances toward a therapeutic device that has the potential to capture cells as they flow through the blood stream and to treat them. Among other applications, such a device could zap cancer cells spreading to other tissues.

 Caf? Latte Batte | File Type: audio/mpeg | Duration: 1:30

At a time when bat populations are declining worldwide, a new University of Michigan study shows the bat's impact on ecological systems. The study reveals that bats exceed birds in their ability to devour coffee-eating insects on organic coffee farms.

 Tiny Tunes | File Type: audio/mpeg | Duration: 1:30

Researchers at the University of Rochester have made it possible to digitally reproduce music in a file nearly 1,000 times smaller than a regular MP3 file by recreating in a computer both the real world physics of a clarinet and the physics of a clarinet player.

 Gasoline Plant | File Type: audio/mpeg | Duration: 1:30

Researchers at the University of Massachusetts-Amherst have made a breakthrough in the development of green gasoline, a liquid identical to standard gasoline yet created from sustainable biomass sources like switchgrass and poplar trees.
