St. Jude study solves mystery of mammalian ears

... the future.” The long-standing argument centers around outer hair cells, which are rod-shaped cells that respond to sound waves. Located in the fluid-filled part of the inner ear called the cochlea, these outer hair cells sport tufts of hair-like cilia that project into the fluid. The presence of outer h...

Cellular message movement captured on video

...dhesions, busy intersections of activity scattered around the cell’s cytoplasmic membrane. Focal adhesions are regions rich with receptors for growth factors and they are also structural attachment points that link the extracellular world to the protein filaments and tubes that comprise a cell’s internal cy...

Agent slows aging in mice

...The longest that mice of this type usually live is around 1,000 to 1,100 days. “If NDGA turns out to extend maximal lifespan by 20 or 30 percent, people would accept that as an important finding,” Miller says. No one excited by these early results in mice is advised to bulk up on creosote bush leaves...

Modeling the restless brain

... of the brain, but this activity only accounts for around 2 to 5 percent of the total activity of the brain. Fluctuations of similar magnitude -- the ones studied by Sporns and Honey -- occur when a person is at rest, doing nothing. The nature of these "resting state fluctuations" is an active topic of ...

Largest synthetic gene ever built offers insights into anti-malarial drug resistance

...use of chloroquine, isolates of P. falciparum from around the globe have developed genetic mutations that make them resistant to that drug as well as other similar agents. Not all mutations found in all resistant isolates are the same, however. Parasites in different geographic regions have developed unique...

Millions of children denied drug that costs less than $3 a year

...le with epilepsy who live in developing countries, around 85% receive no treatment at all. As a result, they experience seizures and the psychological consequences of stigma and discrimination. Regrettably, most of these people, many of whom are children, could return to a normal life by taking a single ...

Research shows cord blood comparable to matched bone marrow

The analysis included transplant outcomes in 785 children younger than 16 who had the diagnosis of...

'Lucky 13' as new gene discovery offers further hope for childhood blindness

...g in collaboration with experts from other centres around the world, identified the gene, which is essential to photoreceptors in the eye, the cells that "see" light. The finding, the thirteenth gene to be linked to Leber’s congenital amaurosis (LCA), comes at a time of hope for the people born with the d...

Undergraduate research shows leaderless honeybee organizing

Though the bee colony is centered around the queen and her reproductive capabilities, findings by Schneider and others indicates that she does not exactly “rule.” Instead, the colony appears to be controlled by the anonymous consensus of the colony’s workers. Though it is of great inter...

Newly discovered antibody may be body's natural defense against Alzheimer's

...rs" can grow into insoluble "fibrils" that cluster around brain cells and are a hallmark of Alzheimer's disease. While monomers are produced from birth and appear to be relatively benign, oligomers have been implicated as potent toxins responsible for Alzheimer's-linked memory loss and brain cell death. Thi...

Physicist cracks women's random but always lucky choice of X chromosome

...aterial for a "protein plug" then begins to gather around both of the XIST suicide genes on each X Chromosome. This starts a race between the two build ups of protein. Inevitably one of these two nascent protein plugs narrowly wins that race and reaches an energy state in which it can pull together all the ...

Small, self-controlled planes combine plant pathology and engineering

Second, the autonomous technology enables us to have coordinated flight with multiple aircraft. In other words, we can have two aircraft sampling pathogens at the same time but...

Study investigates 'divorce' among Galapagos seabirds

A male’s capacity to raise offspring, a quality that can vary with time, may carry more weight with a mate than stellar genes or past breeding succ...

New findings challenge established views on human genome

Carried out by 35 groups from 80 organizations around the world, the research served as a pilot to test the feasibility of a full-scale initiative to produce a comprehensive catalog of all components of the human genome crucial for biological function. “This impressive effort has uncovered many exci...

Exploring the dark matter of the genome

"Drosophila is ideal for studying genomics for many reasons, and especially for studying heterochromatin," says Susan Celniker, a scientist in Berkeley Lab's Life Sciences Division and a lon...

Blood-brain barrier breached by new therapeutic strategy

The new research provides a safe and non-invasive method for delivering therapeutic molecules across the blood-brain barrier. It has the potential to be applied to the treatment of a variety of brain infections and diseases. Th...

Surprising origin of cell's internal highways

Now, researchers at Vanderbilt University Medical Center reveal a surprising new origin for these cellular "highways." In the June issu...
