Right angles are all wrong for tree frog adhesion
04-01-2007 · EurekAlert!Tree frogs have the unique ability to stick to smooth surfaces even when they are tilted well beyond the vertical -- some small tree frogs can even adhere when completely upside down. Conversely when walking or jumping they can detach their toe pads easily. Researchers from the University of Glasgow will present insights into how this fascinating ability is controlled.

- Novel semiconductor structure bends light 'wrong' way -- the right direction for many applications
10-14-2007 · EurekAlert!
A Princeton-led research team has created an easy-to-produce material from the stuff of computer chips that has the rare ability to bend light in the opposite direction from all naturally occurring materials. This startling property may contribute to significant advances in many areas, including high-speed communications, medical diagnostics and detection of terrorist threats.

- Robotics lab helps stroke patients with recovery
12-04-2007 · EurekAlert!
Robotics engineers at Rice University are teaming with doctors from Houston's Memorial Hermann/TIRR to develop a PC-based system for stroke rehabilitation. Sixteen patients are testing a prototype system. They use joysticks to move objects on a computer screen. Using force-feedback technology, the joystick resists moves in the wrong direction and guides patients along the right path. Researchers hope to refine the system to allow stroke patients to recover more quickly.

- Study challenges belief that tree frogs depress metabolic rate after 'waxing' themselves
10-16-2006 · EurekAlert!
Researchers from the University of Florida explore wiping behaviours in a tree frog that waxes itself, and test whether these frogs become dormant to conserve energy during dehydration. Many amphibians have skin that offers little resistance to evaporative water loss. To compensate, these and some other arboreal frogs secrete lipids and then use an elaborate series of wiping motions to rub the waxy secretions over their entire bodies.

- RX for wrong-site surgery -- 2 minutes of conversation
01-23-2007 · EurekAlert!
A study of Johns Hopkins surgeons, anesthesiologists and nurses suggests that hospital policies requiring a brief preoperation "team meeting" to make sure surgery is performed on the right patient and the right part of the body could decrease errors.

- Who says King Alfred burned the cakes?
03-09-2007 · EurekAlert!
King Alfred burned the cakes, right? Wrong. For a start they were loaves -- and for another thing, the Vikings reckon their terrifying-sounding hero Ragnar Hairybreeks should take the blame for this ninth century catering disaster.

- Neuron cell stickiness may hold key to evolution of the human brain
11-02-2006 · EurekAlert!
The stickiness of human neurons may have been a key factor in why the human brain evolved beyond the brains of our primate relatives. In a study comparing the genomes of humans, chimpanzees and other vertebrates, researchers at the US Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and Joint Genome Institute (JGI) found a strikingly high degree of genetic differences in DNA sequences that appear to regulate genes involved in nerve cell adhesion molecules.

Individuals with a high pulse pressure (the difference between the systolic [top number] and diastolic [bottom number] blood pressure), appear to have an increased risk for high-tension open-angle glaucoma, according to a report in the June issue of Archives of Ophthalmology, one of the JAMA/Archives journals.

- Genetic analysis finds greater threat in frog-killing fungus
08-06-2007 · EurekAlert!
A new study led by UC Berkeley researchers suggests that a frog-killing fungus may be harder to fight because of the pathogen's ability to spread over long distances and possibly persist in the environment as a consequence of sexual reproduction. The fungus has already decimated populations of mountain yellow-legged frogs in the Sierra Nevada.
