Leave it to salmon to leave no stone unturned

... 45 pounds or more. The biggest nests are nearly a foot and a half deep and extend up to 17 square yards –about the size of two parking-lot stalls. The rims around these craters can be the bane of boaters who, even with boats meant to navigate in shallow waters, can find their vessels grounded. Smaller s...

Penguins waddle but they don't fall down, UH researchers say

...challenges, such as the elderly, those with leg or foot injuries and toddlers learning to walk. The research findings could even allow the development of more mobile robots. His study on walking stability features dozens of King penguins from Moody Gardens in Galveston. Though these endearing animals m...

Animal brains 'hard-wired' to recognize predator's foot movements, Queen's study suggests

...animals in the wild more easily from a car than by foot may be due to an innate "life detector" tuned to t...o the right or left. The researchers conclude that foot movement is an independent, important visual cue that another animal is nearby. "The observation t...

Researchers release new variety of asparagus

...t is grown from seed. The crown is planted about a foot deep in sandy soils. Spears grow from buds in the crown, and, if not harvested, branch out to form the "fern" which is the feathery green leaves and stems of the plant. Spears are not usually harvested until plants are two years old in order to allo...

Hooked on fishing, and we're heading for the bottom, says scientist

...lex. According to Dr. Pauly, it operates with "one foot deep in illegality," by landing illegal catches, and skirting existing laws through the use of tools such as flags of convenience. And, he says, public policy on marine fish conservation issues is distorted by the fact that most governments view fish...

Skin disease common among Hispanic farmworkers in North Carolina, research shows

...r men, the most common diagnoses were nail fungus, foot fungus and acne. Among the women, diagnoses included excessively dry skin, foot fungus and acne. "While these may not be a direct result of farmwork, it is likely a result of res...

Watch your step when the going gets rough

Placing your foot accurately is a complicated process. If something moves where you plan to place your foot then you can adjust your step while your foot is swinging through. Experts thought previously that i...

Scientists learn to predict protein-stabilizing ability of small molecules

One of the robotic arms holds a tiny video camera, one works as a retractor and the other two replicate the surgeon’s exact hand movements. The camera and instruments are inserted through small keyhole incisions in the patient’s abdomen. Th...

Gene therapy for muscular dystrophy fixes frail muscle cells in animal model, Stanford study finds

...ling muscle. "If you have a single cell that's a foot long and you only correct a few inches, you've done very little," Rando said, "Whereas if you correct it from end to end, you truly cure the disease in that cell." Both Rando and Calos point out that the road to a gene therapy cure for muscular dyst...

Wright bros. upstaged! Dinos invented biplanes

... became even larger than those of Microraptor, but foot feathers were lost. "It is intriguing to contemplate that perhaps avian flight, like aircraft evolution, went through a biplane stage before the monoplane was introduced, said Chatterjee. "It seems likely that Microraptor invented the biplane 125 ...

...images of the surgical site. Focus is adjusted via foot pedals. While laparoscopy allows manipulation of instruments up, down and side-to-side, surgery with the da Vinci allows more natural wrist movement. The robot's arms have wrists with eight degrees of freedom that allow the surgeon "to bend around ...

UF researchers kill resistant bugs one bandage at a time

...hat," Schultz said. Clothing that kills athlete's foot and other fungi could help U.S. soldiers in the field who often don't have time to change or shower, and the substance also could be added to hospital gowns and bedding to stop the spread of resistant bugs, said Schultz, who also serves as the compan...

Study identifies gene in mice that may control risk-taking behavior in humans

... a non-adverse stimulus, a tone followed by a mild foot shock. Normal mice crouch down and stop moving the next time they hear the tone, a physiologic response that indicates they expected a shock. The mice remembered the experience. However, those with a single copy of the neuroD2 gene did not respond to...

Size matters: Preventing large mammal extinction

...ides a way for conservationists to go on the front foot rather than wait for accidents to happen. We can try to work out which species are the ones we can do something for, and do some pre-emptive conservation planning. Of course, prevention is always cheaper than cure." The research means large bodied m...

... the microbial fuel cell. Each chamber was about a foot high and about 6 inches in diameter. The chambers were separated by a special material that allowed protons to move from the negative (anode) chamber into the positive (cathode) chamber. This movement of protons, along with the movement of electrons...

... of declines "if we would only take our collective foot off their neck." "A great deal of habitat from southern British Columbia to California is no longer accessible to salmon or has been altered to their detriment," he writes in the conclusion of his book published by University Press.
