Scientists journey to southern Africa to unravel the secret world of elephant communication

...es buried in the soil, the scientists were able to confirm that low-frequency rumbles and mock charges do, indeed, generate measurable seismic waves that travel along the surface of the ground. In 1999, the UC-Davis team developed a mathematical model predicting that low-frequency vibrations have the potenti...

Small species back-up giant marsupial climate change extinction claim

...ed later in the year, on other sites in the region confirm the stratification of fossils in the creek bed. The dig also failed to unearth evidence of human activity, suggesting they didn't inhabit the region at the same time as megafauna. Queensland Museum Assistant Curator in Geosciences, Scott Hocknull a...

Love's all in the brain: fMRI study shows strong, lateralized reward, not sex, drive

...iting because it's the first physiological data to confirm a connection between romantic love and motivation networks in the brain. "As it turns out, romantic love is probably best characterized as a motivation or goal-oriented state that leads to various specific emotions, such as euphoria or anxiety," Aro...

Strongest proof yet found for prion hypothesis

...Until now, however, scientists have been unable to confirm its validity by causing a TSE in normal lab animals by infecting them with malformed proteins (dubbed "prions" by Prusiner) created entirely in a test tube. Such an approach eliminates the possibility that some other agent might be causing the diseas...

Researchers rein in regulatory RNAs

...Kiyosawa, the lead author on the paper, set out to confirm the presence of SATs in a variety of mouse tissue types and cell cultures, as well as to identify common characteristics of these unique transcripts. Employing a custom-made microarray chip designed to detect strand-specific expression of 1947 SAT p...

Surprising findings reported about iron overload

...ithout HFE mutations. "Our findings in Caucasians confirm reports from previous smaller studies," said Acton. "Our findings in non-Caucasians help everyone understand the prevalence of these conditions in other racial/ethnic groups." He added that many white Alabamians have Celtic origins, with some counti...

Special Imaging Study Shows Failing Hearts Are 'Energy Starved'

...e Proceedings of the National Academy of Sciences, confirm what many scientists have conjectured for years about heart failure, and suggest new treatments designed to reduce energy demand and/or augment energy transfer. “The heart consumes more energy per gram than any other organ,?notes Paul A. Bottomley, ...

NC State scientist finds soft tissue in T. rex bones

...l extracts of this fossil bone. If further studies confirm this, we may have the potential to learn more not only about the dinosaurs themselves, but also about how and why they were preserved in the first place." The research was funded by NC State, the N.C. Museum of Natural Sciences and the National Scie...

Researchers discover molecule that causes secondary stroke

...n their study was small and more work is needed to confirm that vasospasm is more likely to occur in bleeding-stroke patients who have elevated levels of BOXes. ...

Neuronal 'traffic jam' marks early Alzheimer's disease

Novel Asthma Study Shows Multiple Genetic Input Required; Single-gene Solution Shot Down

...ients. "Our results, and those from other groups, confirm that in situations where residual disease remains, adjuvant chemotherapy alone in high-risk breast cancer patients is suboptimal and that the addition of locoregional radiation therapy is important to achieve the highest cure rate," the authors write...

Adding Radiation Therapy To Chemotherapy Improves Survival In Patients With High-risk Breast Cancer
