Researchers have discovered that injecting a simple hormone into leeches creates a novel way to study how hormones and the nervous system work together to produce species-specific reproductive behavior.

Stomach wrap operations may be more effective than acid suppression tablets in the treatment of severe acid reflux, according to a new review. The study shows a more pronounced improvement in symptoms shortly after surgery than with drug treatment.
Men and women with a history of alcohol abuse may not see long-term negative effects on their memory and thinking, but female smokers do, a new study suggests.
Using metal staples to close wounds after orthopedic (joint) surgery can lead to a greater risk of infection than using traditional nylon sutures, concludes a new study.
Scientists investigate differences in woody and herbaceous crop productivity and biomass yield as a function of landscape position at the field scale.
A new study is analyzing how the immune system is involved in damage to the intestines following hemorrhagic shock. While studying the effects of a complement inhibitor given following hemorrhage, it found that Helicobacter infection changes the body's mechanistic response and would therefore affect the therapeutics given to trauma...
Tourists wanting to watch and swim with dolphins are now being urged to keep their distance in a bid to protect both the animals and the local communities whose livelihoods depend on them.
Researchers have discovered a way to make liquid flow vertically upward along a silicon surface, overcoming the pull of gravity, without pumps or other mechanical devices. The research could lead to the design of better computer cooling systems.
Biologists have discovered that a protein from a soil bacterium used to kill insects naturally on organic crops is a highly effective treatment for intestinal parasitic roundworms.
Young Britons see significantly more on-screen smoking in movies than their US peers, finds new research.
The absence of a single gene, called p21, confers a healing potential in mice long thought to be reserved only for creatures like flatworms, sponges, and some species of salamander: regeneration. Researchers demonstrate that mice that lack the gene can regenerate lost or damaged tissue, suggesting that such an ability may be granted to mammals by blocking the effects of...
Researchers in Ireland have gained new understanding of the role played by the cilial protein Arl13b in Joubert syndrome (JS), a rare disorder characterized by developmental delay, mental retardation, and low muscle tone, among other symptoms.
Living through the trauma of war seems to increase the risk of developing asthma, suggests new research.
A group of Argentine scientists have announced that yellow fever is the culprit in a 2007-2008 die-off of howler monkeys in northeastern Argentina, a finding that underscores the importance of paying attention to the health of wildlife and how the health of people and wild nature are so closely...
Diabetics, under the gun to better manage their disease by controlling their food intake and weight, may find themselves in the sticky wicket of needing treatment that makes them hungry, researchers said.
Forensic scientists may soon have a valuable new item in their toolkits -- a way to identify individuals using unique, telltale types of hand bacteria left behind on objects like keyboards and computer mice, says a new study.
The more difficult the decision we face, the more likely we are not to act, according to new research by scientists that examines the neural pathways involved in "status quo bias" in the human brain.
New research findings indicate that some breast cancers continue to be detected as a palpable lump rather than being found through mammographic screening. Patients who presented with palpable tumors -- those detected as a result of breast complaint or during examination -- had larger tumors and were at a more advanced stage at...
Both new diagnoses and a history of non-melanoma skin cancer appear to have become increasingly common, and the disease affects more individuals than all other cancers combined, according to two new reports.
A new experiment shows how adjacent regions affect each other in superconductors, and suggests ways that the materials could be improved by controlling their nanoscopic structures.
Scientists have discovered a molecule that can prevent a toxic protein involved Alzheimer's disease from building up in the brain. They found that in test tube studies the molecule not only prevents the protein from forming clumps but can also reverse this process. Then, using fruit flies with Alzheimer's disease, they showed that the same molecule effectively "cures" the insects of the...
A study of infants finds they respond to the rhythm and tempo of music and find it more engaging than speech. The research suggest that babies may be born with a predisposition to move rhythmically in response to music.
Like a magician who says, "Pick a card, any card," computer scientist Debashis Sahoo seemed to be offering some kind of trick when he asked researchers to pick any two genes already known to be involved in stem cell development. Finding such genes can take years and hundreds of thousands of dollars, but Sahoo was promising the skeptical stem cell scientists that, in a fraction of a second and for...
Men with cardiovascular disease and erectile dysfunction (ED) are at higher risk for death from all causes and also are more likely to suffer cardiovascular death, heart attack, stroke and heart failure hospitalization, according to a new study. Treatments effective in reducing cardiovascular disease had no effect on ED. Erectile dysfunction should be considered a risk factor for cardiovascular...
Given a choice between spending a token to get their absolute favorite food or spending it to have a choice from a buffet of options, capuchin monkeys will opt for variety.
