A case of mistaken identity for the ivory-billed woodpecker?

...s. The Pileated Woodpecker's wings were thought to beat more slowly that the 8.6 beats per second captured on Luneau's video, and its wings have black trailing edges. The trailing edges of the Ivory-billed Woodpecker's wings are white. Aberdeen-based Collinson concludes that Luneau's video shows a bird...

Mosquito genes explain response to climate change

...dshaw said. "Rather than having a bully coming to beat you up at recess everyday, you can take a body-building course and beat up the bully, or you simply can take recess at a different time. Many organisms are taking the latt...

A revolution in the monitoring of unborn babies

For Pacific white shrimp, gender matters when competing for food

...competing for food, male shrimp will almost always beat female shrimp ?even though adult males of the species are typically much smaller than the adult females of the same age. "Both size and gender are important factors in acquiring food," says study author Dustin Moss, "but when you pit male against fe...

Pesticides need sunscreen to beat the heat

...de with a new in-built sunscreen will help farmers beat the heat in crop protection. This means that the bug sprays last longer, as they are protected from the strong rays of sunshine, reports Chemistry & Industry, the magazine of the SCI. This is becoming increasingly important as temperatures rise, ...

Nice guys do finish first in lizards' evolutionary race

...o raid female territories and mate. They generally beat blue-throated lizards, the stay-at-home dad types. The blues stick close to home to protect females and have a buddy system. One blue-throat will do battle with the orange-throat, enabling his buddy stay fit and mate. McAdam explains that the altruis...

Finding paves way for better treatment of autoimmune disease

The ability to easily make large numbers of these cells opens the door to improved treatment and a better understanding of autoimmune diseases such as type 1 diabetes and arthritis, Medical Coll...

UC Davis researchers move biotechnology closer to replacing electronic pacemakers

...mal models such as mice and rats, whose hearts can beat up to 600 times per minute. Large animals such as pigs make for far more realistic models because their anatomy and physiology, including average heart rates of about 70 to 80 beats per minute, are similar to humans. In the current study, research...

Honey helps problem wounds

... respect medihoney is neck and neck in the race to beat the antibiotic mupirocin, currently the local MRSA antibiotic of choice. This is shown by a study recently published by researchers in Australia. In one point medihoney was even superior to its rival: the bacteria did not develop any resistance to th...

Genes affecting blood pressure change as children become adults

Researchers left much-discussed obesity out of this equation, focusing instead on genes and environmental factors directly influencing blood pressure and hemodynamics. The huge twin c...

Study: Paramedics save more lives when they don't follow the rules

...her than beats but can be shocked back into normal beat with a defibrillator. In contrast, the survival rate was only 20 percent in the 3 years before, when the standard CPR protocol was used. The current study, which involved 125 patients, reports the experiences after the revised protocol was implemen...

Study in Science holds promise for a new approach to drug therapy

...t muscle cells, a similar mechanism controls heart beat rate. Many current, best-selling drugs work by binding to G-protein-coupled transmembrane receptors in the place of ligands on the outside of cells. A successful drug will either shut down or turn up the function of the GPCR as compared to its natu...

For one Stanford doctor, the beat goes on during open-heart surgery

...in the room turned suddenly quiet. The beat, beat, beat of the heart monitor filled the air. Ihnken, head tilted, found the spot he was searching for on the heart's backside and, finally, looked up. "Everything OK out there?" Ihnken asked the anesthesiologist breaking the tense silence. "Really stable, ...
