New fossil sheds light on old mystery
...eeding in any other animal. Rather than expand the volume
of its mouth to suck in prey, Dinocephalosaurus expanded the volume
of its throat, in many ways a more effective approach." In addition, the long neck allowed Dinocepha...

enough to allow the animal to swallow the pressure wave that it created as its head lunged forward though the water. By swallowing its own pressure wake that would otherwise signal its approach, the predator may have executed almost undetectable stri...
New research shows air pollution can reduce children's lung function
...uctions in their "forced expiratory volume" -- the volume
of air that can be exhaled after taking a deep breath -- as compared to children living in communities with cleaner air. In healthy people, lungs grow to full capacity during the teenage years, but typically stop growing at age 18. Then, lung capacit...
As informatics grows, Indiana University helps set 'research agenda'
...enhanced our ability to gather data that the sheer volume
of data now outstrips our capacity to deal with it," said Indiana University School of Informatics Dean J. Michael Dunn. "Informatics is taking this seemingly unmanageable flood of data and transforming it into information that helps solve key proble...
A genetic disorder yields insight into genes and cognition
...structural MRI imaging revealed a reduction in the volume
of gray matter in an adjacent brain region. The researchers' studies also showed that impaired input from this region could cause the reduced function. The researchers concluded that "Our observations confirm a longstanding hypothesis about dorsal st...
Why your knees and quads hurt more after running than walking: You're only human

as speed increased and gait changed, the knee extensors increased 4.9-fold during running (to 49% of...
Genetically-engineered 'marathon mouse' keeps on running
...eengineers the heart to allow it to pump a greater volume
of blood. "So, it was not at all obvious that changing one gene in muscle would lead to coordinated changes throughout the body, from the nervous system to the cardiovascular system to the muscle itself. But the remarkable thing about this experimen...

of clear liquid. And the shoulder gland produces a thick brown paste. And both male and female genital glands produce a sticky goo that females might mix with urine, and which might have an effect on the message the female is encoding." Scordato per...
Huge market for forest moss raises concerns

of moss being removed was of concern. In the East, the concern about moss harvests in some areas is sufficiently high that the Monongahela National Forest has stopped issuing any harvest permits. In the Pacific Northwest, some business owners a...

Microarrays, key genome expression trackers, work better when probes are sequence-verified
...ss studies. Furthermore, there is now a tremendous volume
of data, particularly from human clinical specimens, which can't be duplicated, so strategies to improve analysis of (that is, "clean up") existing data sets are needed. One limitation of the application of microarray technology could be due to the f...
