Technique may allow cancer patients to freeze eggs, preserving fertility before starting treatment

...reservation technique allows the eggs to be cooled fast enough that the transformation from liquid to solid is instantaneous. No ice crystals form and the consistency resembles a viscous glassy state. Research so far has used mouse oocytes but U-M expects to make the technology available in the clinic soo...

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

...dentifying mutant fish whose biological clocks run fast or slow, providing the ability to trace the specific genes that create the anomaly. Putting UH a bit ahead of other institutions engaged in this type of research, Cahill and his team will be able to analyze more than 2,000 zebrafish per week. The per...

Researchers devise way to mass-produce embryonic stem cells

...row these cells are costly and don't produce cells fast enough to respond to increasing demands for human embryonic stem cells, said Shang-Tian Yang, a professor of chemical and biomolecular engineering at Ohio State University. Federal rules forbid the federal funding of research on human embryonic stem...

BioMed Central welcomes the new National Institutes of Health public access policy

...ddition to the rapid and high quality peer review, fast publication and high visibility of BioMed Central's Open Access journals. BioMed Central urges all researchers in the life and medical sciences to fulfil the NIH request and to submit their future manuscripts to one of the 130 Open Access journals p...

PET/MRI scans may help unravel mechanisms of prenatal drug damage

...and found significant differences in where and how fast the drug accumulates in maternal and fetal organs. "Understanding how drugs are transferred between a mother and her fetus during pregnancy may help us unravel the mechanisms of the drug's damaging effects on unborn children," said SNM member Helene...

Live fast, die young true for forests too

...e environmental changes. "One implication of this fast turnover rate is that the world¹s most productive forests may be those likely to respond most quickly to such things as climatic change," said Nate Stephenson, a USGS research ecologist in Three Rivers, Calif., and lead author of the article. "You c...

US life expectancy about to decline, researchers say

...o-author of the study. For children in particular, fast food, sugar-sweetened beverages and other high-calorie/low-quality junk foods are major contributors to obesity. "These adverse changes in diet have been driven by a multi-billion dollar marketing campaign by the food industry aimed at young childre...

Molecular Motors Cooperate In Moving Cellular Cargo, Study Shows

Researchers using an extremely fast and accurate imaging technique have shed light on the tiny movements of molecular motors that shuttle material within living cells. The motors cooperate in a delicate choreography of steps, rather than engaging in the brute-force tug of war many scie...

The very unexpected life and death of a leukemic cell

... new study shows that leukemia cells are born at a fast rate and do indeed die. The slow rise in the cell count over time can be attributed to the difference between the birth and death rates of the cells, according to the study. The researchers at the Institute for Medical Research at North Shore-LIJ an...

Open microfluidic and nanofluidic systems

...xt of biomedicine, for example, they could provide fast and detailed analysis of blood samples in the physician's office without the need to wait several days before the sample has been returned from specialized laboratories. Other applications include customized chips for space travel in order to monitor...

The transparent organism: EMBLEM and Carl Zeiss give labs a unique look at life

... tissues in the past. The entire procedure is very fast and in a computer supported post-processing step, one or more stacks of images are assembled into a high-resolution film. Another advantage of SPIM is that the specimen is kept alive in a liquid-filled chamber, allowing scientists to track developme...

Research on Worms Yields Clues on Aging

...d wormscontinued to display the youthful traits of fast body movement and fastpumping of mouthparts during the latter phase of their extended lives.Further tests showed that the anticonvulsants stimulated transmissionof signals in nerves that control body movement.Scientists previously had found genetic m...

Timing is everything: First step in protein building revealed

... the ribosome complex, theresearchers examined how fast the pieces of the ribosome come together,and how long it takes them to fall apart under various circumstances.Their results support the idea that two separate steps take place oncethe instruction's starting point is found: first a structural change i...

Scientists ID molecular 'switch' in liver that triggers harmful effects of saturated and trans fats

..., and the oils used to cook french fries and other fast food. Studies have shown that trans fats not only raise LDL levels in the bloodstream but lower high-density lipoproteins (HDL, or "good" cholesterol) and may have even stronger adverse effects than do saturated fats. The researchers report that whe...
