Recombination protein dynamics observed with single monomer resolution

...cules ?one green and one red ?to the molecule they want to study. Next, they excite the green dye with a laser. Some of the energy moves from the green dye to the red dye, depending upon the distance between them. The researchers then measure the brightness of the two dyes simultaneously. The changing ra...

Study links high levels of nitric oxide to infertility and sperm DNA damage

... over-production of NO in infertile males. We also want to find a cut-off level at which NO changes from having a beneficial effect on sperm to having a negative affect." ...

New egg freezing technique offers hope to hundreds of women

...nd Embryology, gives hope to hundreds of women who want to preserve their future fertility but who, for whatever reason, only have eggs, not embryos, available for freezing. Dr Masashige Kuwayama told a news briefing that although sperm could be frozen, thawed and used for in vitro fertilisation with hi...

Researchers seek to solve mystery of natural HIV control

...f PARC, lead coordinator of the research team. "We want to use that knowledge to develop a first-generation HIV vaccine, which may not cure or prevent infection but could successfully suppress viral levels. Since this natural ability is so rare, we need to work with collaborators around the world to recr...

Heart has enough oxygen to survive hypothermia, CPR crucial

...mount of oxygen the body needs when hypothermic, I want to stress the importance of starting and continuing cardiopulmonary resuscitation (CPR) efforts with all victims of hypothermia," Tveita said. Doctors typically cease CPR efforts in a normothermic patient after 30 minutes. But CPR should continue on ...

Septum keeps neurons in synch, can reduce epileptic seizures by 90 percent

.... "But I would say there is hope," Colom said. "We want to offer people with epilepsy new options," he said, but progress will depend upon funding, he added. Next steps The researchers will repeat the study using animals that are awake and mobile, though it is more difficult to record the brain's disc...

The vicious cycle of rainforest destruction

...nd the atmosphere becomes drier." The researchers want to find out under what conditions rainforest and savanna are able to thrive. It's not a simple question of rainfall: areas in Africa with 1800mm of rainfall a year are rainforest; in South America, areas with the same rainfall are savanna. Other iss...

CHAVI announces international search for genes affecting HIV response

...rector of CHAVI's host genetics research core. "We want to find out why some people naturally hold the virus down to almost undetectable levels while others lose control of it quickly." The newly organized group, called EuroCHAVI, will recruit 600 patients from nine cohorts. "This will be is the largest ...

How IVF could be causing genetic errors in embryos

BGSU biologist trying to crack microscopic code

...and allowed us to identify the key 'words.' Now we want to know what the 'words' mean, and we are starting by asking what happens when we mix the 'dialects.' "It's genetic tinker toys," and an area, he adds, in which BGSU doctoral student Kerry Brinkman is "breaking new ground." Larsen and his graduat...

UF scientists restore sight to chickens with blinding disease

...sponding visually to the environment, but I didn't want to believe it. Scientists always doubt what they see -- it's intrinsic to how we operate. So I did this simple little test, drawing little dots on a piece of paper. The chick, which was standing on the table, came over to the paper and started peckin...

Mechanism identified for promising neurological drug

...ke ALS, it could be a reasonable tradeoff. But you want to have your eyes open." Another implication has to do with gender differences: PARP-1 stimulates an inflammatory response much more strongly in males than in females, "across all species that have been looked at," says Swanson. "It's unclear why th...

...hing movement. "Rehab is about training, and you want to be able to train the slow-learning system to be successful," says Shadmehr. As a next step, the team is interested in uncovering which parts of the brain are responsible for slow-learning. They hope that teasing this system apart will not only im...

In addition, a question still outstanding is whether non-responders would benefit from sildenafil at a higher elevation. ...
