Gap-climbing fruit flies reveal components of goal-driven behaviors

Like humans, other animals are faced with everyday obstacles in their physical environments and must engage appropriate decision-making and motor skills to deal with them. Navigating these obstacles can involve highly complex events in mammals and other vertebrates, but in new work, researchers have employed an ingenious obstacle-based system for studying the control and structure of goal-oriente...

MicroRNA may have fail-safe role in limb development

A tiny strand of molecules plays a role in how our arms and legs develop and grow - a finding that sheds light on perplexing bits of material once dismissed as genetic "junk," say scientists at the University of Florida and Harvard University. The research, available today in the online edition of Nature, may help scientists understand whether bits of RNA called microRNAs act as protective...

How low can you go? Ants learn to limbo

Have you ever tried to do the limbo? For ants it's a way of life! Scientists at the University of Zurich have discovered that ants are able to learn how to visually judge the height of horizontal barriers so that they can successfully crawl under it without slowing down. Tobias Seidl will be presenting his latest research findings at the Annual Meeting for the Society for Experimental Biology on...

UF scientists discover evolutionary origin of fins, limbs

Performance on the dance floor may not always show it, but people are rarely born with two left feet. We have genes that instruct our arms and legs to grow in the right places and point in the right directions. They also provide for the spaces between our fingers and toes and every other formative detail of our limbs. Evolutionarily speaking, the genetic instructions used to construct and...

Some people would give life or limb not to be fat

Nearly half of the people responding to an online survey about obesity said they would give up a year of their life rather than be fat, according to a study by the Rudd Center for Food Policy and Obesity at Yale. The 4,000 respondents in varying numbers between 15% and 30% also said they would rather walk away from their marriage, give up the possibility of having children, be depressed, o...

Bone marrow transplants for limbs

Scientists have observed that bone marrow cells can make new blood vessels, when transplanted into limbs with poor circulation. In peripheral arterial disease, circulation in the legs is severely restricted because the arteries are narrowed. //The result is pain and disability. In severe cases, the limb may even need amputation to avoid gangrene and death. Researchers in Osaka, Japan,...

Treating Blocked Arteries In The Lower Limbs

Lower extremity ischemia, or abnormal circulation, occurs when arteries in the abdomen or pelvis narrow or become completely blocked // by the build-up of plaque deposits. As a result, not enough oxygen-rich blood gets to the legs, causing cramps and pain, and making it difficult to walk or exercise. The iliac arteries are large arteries in the pelvis that supply blood to the legs. Rese...

US Kidney Failure Rates show Stabilization After 20-Year Climb

New research from the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) of the National Institutes of Health have shown stabalisation of annual increases from 5 to 10 percent//, rates for new cases of kidney failure. However worryingly there is still a dramatic racial disparity. The average annual increase of kidney diseases has been less than 1 percent since...

Limb Regeneration In Humans: A Future Possibility

Recently, a study has been launched, which, if fruitful, may enable future generations to heal without scarring and grow their own replacement limbs. A research team at Manchester University, headed by Dr Enrique Amaya//, and partly funded by The Healing Foundation charity, is looking to animals for clues to how the body can regenerate. Prof Amaya will focus on the genetics of wound hea...

US life expectancy climbs to a new high

Deaths from heart disease, cancer, and stroke, three leading killers in the U.S., all dropped in 2003. They were down 2 percent to 5 percent.// Also, Americans' life expectancy increased again in 2003, up from 77.3 the year before. By comparison, it was 75.4 in 1990. Life expectancy in the U.S. has increased almost without interruption since 1900, because of several factors,...
