Recognizing new aneurysm syndrome can save lives
... bones, a condition called craniosynostosis. "It's surprising that a syndrome with this many outward features escaped notice until now," says Dietz, "but now that we know it exists, it's critical that doctors look for it." For example, the parents of an 18-month-old girl had brought her to the clinic because o...Multi-purpose protein regulates new protein synthesis and immune cell development
...nd the Howard Hughes Medical Institute reveals the surprising finding that this same signaling protein is required for the formation of immune cells called B lymphocytes. "This is a unique signaling pathway," says Randal Kaufman, Ph.D., a professor of biological chemistry in the U-M Medical School and an HHMI i...New study in JAMA details trends in diagnosis, treatment of brain tumors

"The incidence of depression is very high and very few of these patients are treated for depression. This isone patient management to...The opportunity for canalization and the evolution of genetic networks
...enotypes. Studies of genetic networks have shown a surprising degree of robustness to variation, regardless of whether the variation comes from a change within or outside of the network. One explanation for this pattern is that evolution has acted to create genetic networks that are robust to mutational defect...Marsh-dwelling mole gives new meaning to the term 'fast food'
...n the split millisecond timing involved, it is not surprising that the moles frequently make mistakes. In a series of trials where the researchers set out worm sushi, they found that the moles started to move in the wrong direction and had to suddenly reverse themselves one out of three times.

A surprising prediction of the new theory is that the experimentally observed polymorphism of the wetting liquid depends only on two parameters: (i) the channel geometry, i.e., the ratio of the channel depth to the channel width; and (ii) the interaction between ...Singers (and parents) take note: Worst songbird rehearsals precede best debuts
...g birds learn the art of song, but it does so in a surprising way. The study reveals that when zebra finches first wake up, they are dramatically worse singers than they were the previous day. Moreover, individual birds that initially perform the worst during their morning "rehearsals" eventually become the bes...Scientists rid stem cell culture of key animal cells

Moreover, Xu made the surprising discovery that the very molecules that encourage human embryonic stem cells to differentiate appear to inhibit differentiation in mouse embryonic stem cells. Aside from feeder cells, two other sources of animal material remain in stem cell culture ma...FSU anthropologist leads incredible journey through 'hobbit' brain

Those features, which correlate to initiative-taking and advanced planning, might explain the tools and signs of cooperativ...Hydrogen and methane provide raw energy for life at 'Lost City'

In surprising contrast, researchers discovered Lost City has a diversity of "larger" organisms that's as high, or higher, than any known black-smoker vent sites. Missing from Lost City are the tubeworms, abundant shrimp and other readily observed organisms that he...Discovery clarifies role of peptide in biological clock
...P synchronizes pacemakers," he said. It is surprising that the process is regulated by a peptide, usually a slow signaling agent, rather than a neurotransmitter, associated with fast events, Herzog said. "We're trying to understand the mechanics of how the system synchronizes and the seco...Grizzlies set to invade high Arctic?
