Defect in one of nature's oldest proteins may be an underlying cause in human miscarriages

University of Rochester scientists studying a vital protein called Serum Response Factor (SRF) in mice have learned new and unexpected facts about SRF's role in early cardiovascular development, and how a defect in this gene may be an underlying cause in human miscarriages.

New virtual microscopy system

Researchers at the universities of Helsinki and Tampere (Finland) have developed a new virtual microscopy system, which allows users digitize entire microscope glass slide specimens, and then create a virtual slide with the quality and resolution similar to the original glass slide viewed on a microscope.

Scientists create world’s smallest test tube

Oxford scientists have made it into the Guinness Book of World Records by making the world’s smallest test tube – so tiny that around 300 billion would fit onto a full stop on this page.

Novel enzyme in sperm is essential for spontaneous and independent movement

A study led by scientists at the University of North Carolina at Chapel Hill has found that a novel enzyme in sperm is essential for spontaneous and independent sperm movement as well as male fertility.

Fluorescent protein tool may speed identification of molecular changes that reveal cells' inner workings

Scientists at Johns Hopkins and the University of Texas Medical Branch have created a new tool that easily reveals when and where a key cellular signal is active.

Obesity statistics are as bogus as weight-loss scams

The weight-loss industry is finding itself in the crosshairs of the Federal Trade Commission's "Operation Big Fat Lies" -- a crackdown on slimming down pills, powders and patches that are too good to be true. The Center for Consumer Freedom (CCF) recommends that grossly exaggerated statistics and hype from pharmaceutical and weight-loss companies about the nation's so-called "obesity epidemic" also be placed under the federal microscope.

Crystal structure of protein AIRs kinase uncovered

Cornell University researchers, who are trying to understand how proteins evolve and function by looking at their structural features, have uncovered the crystal structure of a protein involved in making the building blocks of DNA correctly.

Findings could lead to improvements in the next generation of implantable cardioverter defibrillators

For people who suffer from a rapid heartbeat condition called tachycardia, an implanted device can usually nudge the racing blood pump back into a normal rhythm by applying electrical pulses to the heart.

Ductal lavage is not an effective method for detecting breast cancer

Ductal lavage--a method used to collect cells from the milk ducts of the breast--has been proposed as a screening tool for cancer detection because ducts that yield fluid were thought to be more likely to contain cancer cells.

Research shows brain cells move like a two-stroke engine

Following the often-quoted advice of Yogi Berra — "You can observe a lot by just watching" — Rockefeller University scientists show that nerve cells in the developing brains of humans and other mammals move in a two-part "step" led by a structure within the cell called the centrosome.

Robotic microscope shows how mutant Huntington's disease protein affects neurons

Using a specially designed robotic microscope to study cultured cells, researchers have found evidence that abnormal protein clumps called inclusion bodies in neurons from people with Huntington's disease (HD) prevent cell death.

Carbon nanotubes offer a new approach to gene therapy

Many genes that are related to particular diseases have now been identified. Scientists are trying to use this knowledge to treat diseases.

First use of technology called ubiquitin-mediated fluorescence complementation to study a cell-signaling mechanism called ubiquitination

Researchers at the University of Michigan Medical School and Howard Hughes Medical Institute have found a way to see proteins in cells that have been tagged by a molecular “sticky note” called ubiquitin.

In a world first, scientists have successfully grown square bacteria in the lab

In a world first, Australian scientists have successfully grown an unusual square-shaped bacterium found in salt lakes that has mystified scientists for a quarter of a century.

Novel compound that resembles vitamin E halves the size of tumors and the ability of cancer to spread

By studying cancer in mice, researchers at The University of Texas at Austin have gained preliminary evidence that a novel compound that resembles vitamin E halves the size of tumors and the ability of cancer to spread to other body sites.

Microdebrider better than CO2 laser for removal of most pediatric airway lesions

Citing improved safety and effectiveness at lower cost, a major medical center has adopted the microdebrider to replace the CO2 laser for removal of most pediatric airway lesions, including stenoses, granulation tissue, and cysts.

Jellyfish advance science

Salmon fishermen trolling along the waters off Puget Sound in Washington are often witness to an awesome sight when they haul in their catch: salmon captured in nets that glow brilliantly against the nighttime sky.

Researchers have discovered a possible way to distinguish lethal from localized prostate cancers

If future studies show their test -- measuring the level of activity of a signaling pathway called Hedgehog -- can predict which prostate cancers will spread, the results could revolutionize decision making processes for prostate cancer patients, the researchers say.
