AUSTIN, Texas — Anthropology researchers from The University of Texas at Austin have confirmed a direct link between upright two-legged (bipedal) walking and the position of the foramen magnum, a hole in the base of the skull that transmits the spinal cord.

The study, published in a forthcoming issue of the Journal of Human Evolution, confirms a controversial finding made by anatomist Raymond Dart, who discovered the first known two-legged walking (bipedal) human ancestor, Australopithecus africanus. Since Dart’s discovery in 1925, physical anthropologists have continued to debate whether this feature of the cranial base can serve as a direct link to bipedal fossil species. (more…)

Legacy Soil Pollution: Higher lead levels may lie just below surface

A study of data from hundreds of soil samples taken around six old water tower sites in southern Rhode Island finds that even when lead levels on the surface are low, concentrations can sometimes be greater at depths down to a foot. The findings inform efforts to assess the effect of lead paint from old water towers on surrounding properties.

PROVIDENCE, R.I. [Brown University] — A newly published analysis of data from hundreds of soil samples from 31 properties around southern Rhode Island finds that the lead concentration in soil at the surface is not always a reliable indicator of the contamination a foot deeper. The study, led by Brown University Superfund Research Program researchers at the request of the Rhode Island Department of Health (RIDOH), informs ongoing efforts to assess the impact of the state’s legacy of lead-painted water towers.

Rekordtemperaturen und Überschwemmungen – Superlative in immer kürzeren Intervallen. Und der Mensch hat das zum größten Teil selbst zu verantworten.

Die Fakten sprechen eine deutliche Sprache: Die Erde erwärmt sich weiterhin in einem rasanten Tempo und die Meeresspiegel steigen stärker an als bisher prognostiziert. Das besagt der jüngste Report des sogenannten Zwischenstaatlichen Ausschusses für Klimaänderungen (IPCC – Intergovernmental Panel on Climate Change), der am Freitag, dem 27. September in Stockholm veröffentlicht wurde. (more…)

Scaling Up Personalized Query Results for Next Generation of Search Engines

North Carolina State University researchers have developed a way for search engines to provide users with more accurate, personalized search results. The challenge in the past has been how to scale this approach up so that it doesn’t consume massive computer resources. Now the researchers have devised a technique for implementing personalized searches that is more than 100 times more efficient than previous approaches.

At issue is how search engines handle complex or confusing queries. For example, if a user is searching for faculty members who do research on financial informatics, that user wants a list of relevant webpages from faculty, not the pages of graduate students mentioning faculty or news stories that use those terms. That’s a complex search. (more…)

University of Washington researchers have performed what they believe is the first noninvasive human-to-human brain interface, with one researcher able to send a brain signal via the Internet to control the hand motions of a fellow researcher.

Using electrical brain recordings and a form of magnetic stimulation, Rajesh Rao sent a brain signal to Andrea Stocco on the other side of the UW campus, causing Stocco’s finger to move on a keyboard. (more…)
