Womb needed for proper brain development

...e premature infants' brains were done at birth and again when they were discharged from hospital, generally around 36 weeks since conception. They were compared to the brain ultrasounds taken in utero at about 26 weeks gestation and at birth in other studies to a matched group of 38 full-term infants. M...

Mining biotech's data mother lode

... growing every day. Finding relevant data there is again not a trivial task. Dr Schroeder gives an example. "The medical faculty here were studying pancreatic tumours. They found 1,000 genes over expressing. Using our software they were able to find, among others, three protein interactions that were par...

Deep treasure to be found in Oculina Bank

...ions of snappers and groupers recovering enough to again form large breeding aggregations in the area. "We need to establish a statistically and scientifically sound basis to assess whether the habitat and fisheries are changing over time, and whether the reserve and enforcement are working," says Reed. ...

... 150mm. In the laboratory itself photographs are again taken in order to identify features peculiar tot he animal and, finally, the classification of the species in question is presented in the specialist literature. In the previous campaign, expedition members discovered a new species of vermes. The na...

New amphibian species result from exploration, not from rule changes

...n in long-recognized species, a result that argues again taxonomic inflation as the explanation for the growth. Moreover, the Mantellidae include few subspecies that could complicate an analysis. Köhler and colleagues credit the boost in the number of amphibian species descriptions to new bioacoustic and g...

Restaurant seafood prices since 1850s help plot marine harvests through history

An essential regulator of body weight revealed

...eated with diphtheria toxin early in life and then again as adults continued to eat normally. "Killing these neurons before they're functionally engaged gives the developing mouse brain a way to compensate," Palmiter said. "But it's still a tall challenge. You're asking some other neuron, presumably, to ...

Molecular Partners Required For Appropriate Neuronal Gene Repression

...ls or making the HA inactive allows myelin to once again form. "It is our hope that we can interfere with this disease process at one or multiple stages," explained Back. "Of course for those already battling a myelin-destroying disease, you would want to try and promote the return of myelin-forming cells...

How fish hear and make sounds at same time

...the male fertilizes. The next night, the male hums again to attract a new mate. In one season, a successful male may end up fertilizing several thousand eggs. During mating season, houseboat owners in San Francisco Bay have complained that their homes vibrate from the humming fish, which sound like a high...

Firefly protein lets researchers monitor molecule linked to cancer

...options at the start, narrowing in the middle, and again fanning out among many options at the end. "At the waist of that hourglass is IKK," he explains. "This appears to put it in a position to be the key regulator of the pathway, and that has made it a subject of great interest both from the perspective...

MWG Biotech expands siMAX?siRNA portfolio with new scales, lengths and design tools

...?and becomes a second-stage larva. The larva molts again at 72 hours to become a third-stage larva. At 120 hours ?five days after the egg was laid ?the larva enters metamorphosis and becomes a "prepupa" for 12 hours. Then "the head pops out of the front end of the animal, and its legs and wings elongate,"...

Locusts' built-in 'surface analysis' ability directs them to fly overland

...the northern tip of the gulf did some of them turn again east in the direction of Aqaba and other areas of Jordan, as well as straight north over southern Israel. This observation led to examination by scientists of the Hebrew University of Jerusalem Department of Evolution, Systematics and Ecology and th...

...of time it took for human cancers to begin growing again in mice, said the radiation biologists from the Duke Comprehensive Cancer Center. Each therapy alone had limited or no benefit on the tumor, because tumors are skilled at circumventing individual therapies and finding new ways to grow. But together,...
