Advanced genomics and proteomics improve the diagnosis and treatment of a deadly lung disease

...o?" Knowing Dicer's structure, scientists can now begin to tease out the mysteries of how Dicer functions, Doudna said. In particular, scientists would like to know how Dicer is involved in downstream events, how it hands off the cleaved RNA and directs it to the right gene targets. Resolving the structu...

The development of amyloid plaques in the brain tissue of Alzheimer patients is a central factor in the search for a therapy for Alzheimer's disease. A lot or not much of the amyloid precursor pr...

NJIT engineer poised to take stem cell research a step forward

...er such treatment, the patient's spinal cord would begin to heal." Working with Michael Jaffe, PhD, professor of biomedical engineering and chemistry at NJIT, Arinzeh will make what are known as nano-scaffolds. Scaffolds are biomaterials that stem cells attach to and, with a bit of luck, grow into the ...

'Nano-keys' bind cell receptors and trigger allergic reactions

...lead to the release of histamines. Such processes begin on the nanoscale (a nanometer equals one-billionth of a meter) -- at the molecular level on the cell's surface and lead to a system-wide response. At present, very little is known about the structural changes caused by receptor clustering that allow ...

In the mind's eye: How the brain makes a whole out of parts

...re present. Milliseconds later, however, neurons begin to react exclusively to combinations of shape fragments, rather than to individual fragments. In other words, the brain begins to put the pieces together to form larger sections, in the same way that an artisan might fasten discrete shards of stained...

Born with a love of speech

... such that at about six months gestation the fetus begin to hear a range of frequencies. Thus, there's the possibility that newborns preferentially listen to speech because they're used to it from their in-utero tuning-in. But, which speech sounds actually get through the uterine sound barrier to the fetu...

Discovery of new molecular tools for biosynthesis could lead to advances in use of pectin

This study had limited numbers for estimating the risk of using a phone over a long period. Early mobile phones were designed to use analogue signals and emitted ...

Male rivalry increases when females at most fertile, say researchers

...oking men only when the females facial preferences begin to shift prior to ovulation. "Face shape and structure are good indicators of dominance. Men with large eyes, rounded chin and full lips, are viewed as more feminine and are chosen as long-term partners. They are not, however, seen as dominant. ...

UCLA scientists find male gene in brain area targeted by Parkinson's

... disease occurs when cells in the substantia nigra begin to malfunction and die. These brain cells produce a neurotransmitter called dopamine that communicates with the brain areas controlling movement and coordination. As the cells die off, they produce less dopamine. This slows the delivery of messages...
