How the environment could be damaging men's reproductive health

... a genuine association or not." The study did not find a statistically significant difference between boys born to mothers who smoked or who worked in a potentially harmful environment where they might be exposed to heat, vibration or chemical, but the prevalence of cryptorchidism was slightly higher. It...

Programmable cells: Engineer turns bacteria into living computers

...: Sadly no picture is available; however, you can find one in an article from last year , describing the group's research. In a step toward making living cells function as if they were tiny computers, engineers at Princeton have programmed bacteria to communicate with each other and produce color-coded...

UCLA launches $20 million stem cell institute to investigate HIV, cancer and neurological disorders

...ancing the full potential of stem cell research to find novel and more effective therapies to treat many diseases for which present-day therapy is either unsatisfactory or unavailable." Because the university and medical school at UCLA are located on the same campus, researchers are well positioned to co...

Wisconsin researchers identify sleep gene

...haviors we look at, in terms of sleep, the more we find that sleep in fruit flies is very, very similar to sleep in mammals," Cirelli says. Like humans, fruit flies generally are quiet and immobile for between six and 12 hours each night and lose most of their ability to respond to stimuli, the researche...

Camera Traps Catch Eye of the Tiger

...cientist for WWF's tiger program. "We're racing to find out as much about them and where they live as we c...4, field staff began handing out questionnaires to find out if local people had seen any tigers. Scientists then conducted a track survey, in which they att...

Researchers devise way to mass-produce embryonic stem cells

... for these cells is steadily growing. "We have to find a way to mass-produce them because traditional cell culturing methods can't meet the projected high market demand for stem cells," Yang said. He and Anli Ouyang, a doctoral student in chemical engineering, grew mouse embryonic stem cells in a biorea...

A frog's life is food for thought

...heavy rain, sometimes for as little as a week - to find food and build up fat reserves. During the study ... into aestivation and woke them up and fed them to find out how quickly they got everything going again." Ms Cramp's results show that animals can maintain...

Stem Cell Research Shows Potential for Replacing Tissue Damaged in Heart Attacks

...licable to human ES cells. The ultimate goal is to find out whether cardiac myocytes from ES cells can repair diseased or damaged adult myocardium in non-human models. This last question is being answered in collaboration with John Auchampach, Ph.D., associate professor of pharmacology & toxicology, a...

Stem cells from brain transformed to produce insulin at Stanford

...cing insulin was exciting. Kim's next step was to find out if the cells could perform the same feat in a mouse. The group transplanted the cells into a cavity in the kidney where other types of insulin-producing cells have been found to survive. When the blood sugar went up in these mice, the cells once ...

Increased risk of osteoporosis associated with gene that one in five people have

...h younger group of women. My guess is that we will find that females with this variant gene are breaking down estrogen rapidly from the day they are born. In that case, they would never achieve an adequate peak bone density and would lose even more bone mass after menopause. If we can catch them at an ear...

New Drugs For Bad Bugs: UF Approach Could Bolster Antibiotic Arsenal

Key mechanism in genetic inheritance during cell division identified

...r cells. How this works, however, was unknown. To find answers, the Berkeley researchers used a purified, reconstituted Dam1 complex, obtained from genetically engineered E. coli bacteria, and compared its effects on microtubules in vitro to the effects caused by certain Dam1 mutants. Their analysis shed...

Gene Therapy Cures Inherited Liver Disease In Rats

Glow-in-the-dark zebrafish at UH hold keys to biological clocks

...minometer. "This has given us the tool we need to find other parts of systems that influence biological clocks," Cahill said. "We are optimistic that this will shed light upon such things as reproduction in other light-dependent animals." These findings have laid the groundwork for further study along t...

New insight into regulation of blood stem cells

...searchers used random mutagenesis and screening to find animals with hematopoiesis defects, and they used genetics to identify the causative gene. One line mapped to a mutation in the gene c-Myb, which has a known role in regulation of blood formation. Interestingly, they found that c-Myb is not required...

Love's all in the brain: fMRI study shows strong, lateralized reward, not sex, drive

You just can't tell where you might find love these days. A team led by a neuroscientist, an anthropologist and a social psychologist found love-related neurophysiological systems inside a magnetic resonance imaging machine. They detected quantifiable love responses in the brains of 17 youn...

Solutions that reduce death of marine life reeled in by International Smart Gear Competition

...enting fishermen, fisheries, policy and science to find solutions that will reduce the unnecessary decline of vulnerable species due to bycatch. Applicants from 16 countries applied their ingenuity and expertise to solving this global problem. WWF and its partners will assist the winners with making their...

Scientists identify genetic pathways essential to RNA interference

...s or animals. They used the RNAi process itself to find new genes that participate in the gene-silencing mechanism, which someday may help to fight human disease. The report will appear in the journal Science and is receiving early online release on the Science Express website at http://www.sciencexpress....

Defenseless plants arm themselves with metals

...ontaminants from the environment. "Our goal is to find the high-level regulator - the one gene or group of genes that turns a plant into a hyperaccumulator," said David Salt, associate professor of plant molecular physiology in Purdue's horticulture department. "But we have no way to know what that gene ...

Youth With HIV Take More Risks After New Meds Introduced

...-positive youth are taking more risks as well. To find out, they compared behaviors between 349 teens with HIV in Los Angeles, San Francisco, New York and Miami between 1994 and 1996 with 175 teens with HIV in the same cities between 1999 and 2000. Although the two groups did not include the same people,...
