Prevention is key, March of Dimes says
Death or severe cognitive and neuromotor impairment are common outcomes among extremely premature infants (fewer than 26 weeks gestation), according to a British study published today in The New England Journal of Medicine. "Prematurity is a common, serious problem in America and unfortunately, the number of preterm births is rising each year," said Scott D. Berns, M.D., M.P.H., FAAP, vice president for chapter programs of the March of Dimes. "Too many babies are born extremely premature in this country, and the result is that many of them die in the hospital or suffer lifelong consequences, including cerebral palsy, mental retardation, chronic lung disease, blindness and hearing loss."
"More research on the underlying causes of preterm birth is needed if we are to reverse this trend," Dr. Berns said. "The March of Dimes wants to prevent prematurity from occurring in the first place -- we want every birth to be a healthy one."

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...

Physicists in the Laboratory for Attosecond Physics (run jointly by LMU Munich and the Max Planck Institute for Quantum Optics) have developed an attosecond electron microscope that allows them to visualize the dispersion of light in time and space, and observe the motions of electrons in atoms.
The most basic of all physical interactions in nature is that between light and matter. This interaction takes place in attosecond times (i.e. billionths of a...
