Scientists: New Device Accurately Identifies Cancer in Seconds

AUSTIN, Texas – A team of scientists and engineers at The University of Texas at Austin has invented a powerful tool that rapidly and accurately identifies cancerous tissue during surgery, delivering results in about 10 seconds—more than 150 times as fast as existing technology. The MasSpec Pen is an innovative handheld instrument that gives surgeons precise diagnostic information about what tissue to cut or preserve, helping improve treatment and reduce the chances of cancer recurrence.

Ancient tree reveals cause of spike in Arctic temperature

A kauri tree preserved in a New Zealand peat swamp for 30,000 years has revealed a new mechanism that may explain how temperatures in the Northern Hemisphere spiked several degrees centigrade in just a few decades during the last global ice age.  (more…)

UA Geoscientists Take a Crack at Paradox Basin’s Mysteries

With the help of a $1 million grant from the W.M. Keck Foundation, geoscientists are gearing up to study subsurface fluid-rock systems, complex interactions between underground fluids such as oil or groundwater, and how they influence the rocks through which they move. (more…)

In der Wissenschaft teilen vor allem Männer ihr Wissen untereinander

Studie zeigt geschlechterspezifische Kooperationsbereitschaft auf

Auch wenn sich internationale Forschung immer mehr zu einem stark kompetitiven Feld entwickelt, sind WissenschafterInnen meist sehr gewillt ihr Wissen und ihre Arbeit mit anderen zu teilen. Dies gilt vor allem für den Austausch unter männlichen Kollegen, weniger allerdings für Frauen untereinander, deren Kooperation mit ihren männlichen Kollegen sowie für Männer, die ihre Arbeit mit Frauen teilen sollten. Ein internationales Forschungsteam um den Kognitionsbiologen Jorg Massen hat diese Verhaltensmuster unter ForscherInnen aufgedeckt und in der Fachzeitschrift “Scientific Reports” veröffentlicht.  (more…)

Tarzan Robot Swings on Cables to Monitor Crops in the Field

A two-armed robot named Tarzan, swinging along elevated cables, could allow farmers to monitor fields continuously at lower cost while avoiding interference with plants.  

Swinging – or brachiation – is an energy-efficient way to travel because gravity is doing most of the work,” said Ai-Ping Hu, a senior research engineer at the Georgia Tech Research Institute (GTRI). The lightweight robot has aluminum arms and 3D-printed hands with sensors. The eight-pound robot swings back and forth with one hand on the cable, gaining momentum until its second hand detects the cable overhead and grips it. This swinging motion replicates a gibbon’s movement along a tree limb or vine.  (more…)
