*Some Dinosaurs Were as Warm as Most Modern Mammals*

PASADENA, Calif.—Were dinosaurs slow and lumbering, or quick and agile? It depends largely on whether they were cold or warm blooded. When dinosaurs were first discovered in the mid-19th century, paleontologists thought the y were plodding beasts that had to rely on their environments to keep warm, like modern-day reptiles. But research during the last few decades suggests that they were faster creatures, nimble like the velociraptors or T. rex depicted in the movie Jurassic Park, requiring warmer, regulated body temperatures like in mammals.

Now, a team of researchers led by the California Institute of Technology (Caltech) has developed a new approach to take body temperatures of dinosaurs for the first time, providing new insights into whether dinosaurs were cold or warm blooded. By analyzing isotopic concentrations in teeth of sauropods, the long-tailed, long-necked dinosaurs that were the biggest land animals to have ever lived—think Apatosaurus (also known as Brontosaurus)—the team found that the dinosaurs were about as warm as most modern mammals.

Breaking the Chain: ‘Molecular cap’ Blocks Processes that Lead to Alzheimer’s, HIV

A new advance by UCLA biochemists has brought scientists one step closer to developing treatments that could delay the onset of Alzheimer’s disease and prevent the sexual transmission of HIV.

The researchers report that they have designed molecular inhibitors that target specific proteins associated with Alzheimer’s disease and HIV to prevent them from forming amyloid fibers, the elongated chains of interlocking proteins that play a key role in more than two dozen degenerative and often fatal diseases.

*Internet Users in Germany, Turkey, Spain and UK Watch Average of At Least 30 Minutes a Day of Online Video*

LONDON, UK, 14 June, 2011 – comScore, Inc., a leader in measuring the digital world, today released April 2011 data from the comScore Video Metrix service, showing that Germany leads in online video viewing across several reporting metrics for the European countries currently reported in comScore Video Metrix (France, Germany, Italy, Russia, Spain, Turkey and UK).

“Online video is beginning to compete with traditional television viewing for people’s attention, and Internet users in several European countries are leading the way,” said Mike Read, comScore SVP of Europe. “Germany is not only the largest European market for online video viewing but also the most engaged at nearly 20 hours per viewer per month, while several other countries are not far behind.” (more…)

‘Ancient Hominid Males Stayed Home While Females Roamed’

The males of two bipedal hominid species that roamed the South African savannah more than a million years ago were stay-at-home kind of guys when compared to the gadabout gals, says a new high-tech study led by the University of Colorado Boulder.

The team, which studied teeth from a group of extinct Australopithecus africanus and Paranthropus robustus individuals from two adjacent cave systems in South Africa, found more than half of the female teeth were from outside the local area, said CU-Boulder adjunct professor and lead study author Sandi Copeland. In contrast, only about 10 percent of the male hominid teeth were from elsewhere, suggesting they likely grew up and died in the same area. (more…)

*Males Nearly Twice as Likely as Females to Use Mobile Banking*

LONDON, UK, May 27, 2011 – comScore, Inc., a leader in measuring the digital world, today released data from the comScore MobiLens service which showed that 20 million mobile users across the five leading European markets (UK, France, Spain, Germany and Italy), representing 8.5 percent of mobile subscribers in these markets, accessed their bank account via a mobile phone in March 2011. Since August 2010, the first month this activity has been measured in MobiLens, there has been a 15.4 percent rise in mobile bankers which has been largely driven by smartphone users who accounted for 70 percent of the mobile banking market in March 2011. Among Smartphone owners the number of banking users has risen by 40 percent since August 2010. (more…)

Sharpening The Nanofocus: Berkeley Lab Researchers Use Nanoantenna to Enhance Plasmonic Sensing

Such highly coveted technical capabilities as the observation of single catalytic processes in nanoreactors, or the optical detection of low concentrations of biochemical agents and gases are an important step closer to fruition. Researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab), in collaboration with researchers at the University of Stuttgart in Germany, report the first experimental demonstration of antenna-enhanced gas sensing at the single particle level. By placing a palladium nanoparticle on the focusing tip of a gold nanoantenna, they were able to clearly detect changes in the palladium’s optical properties upon exposure to hydrogen. (more…)

Evolution of Human ‘Super-Brain’ Tied To Development of Bipedalism, Tool-Making

Scientists seeking to understand the origin of the human mind may want to look to honeybees — not ancestral apes — for at least some of the answers, according to a University of Colorado Boulder archaeologist.

CU-Boulder Research Associate John Hoffecker said there is abundant fossil and archaeological evidence for the evolution of the human mind, including its unique power to create a potentially infinite variety of thoughts expressed in the form of sentences, art and technologies. He attributes the evolving power of the mind to the formation of what he calls the “super-brain,” or collective mind, an event that took place in Africa no later than 75,000 years ago. (more…)

*comScore Releases First European Data on Media Tablet Users from MobiLens Service*

London, UK, 21 April, 2011 – comScore, Inc., a leader in measuring the digital world, today released the results of an EU5 (UK, Germany, France, Spain, and Italy) study of media tablet owners, based on data from the comScore MobiLens service. The report includes comScore’s first publicly available data showing demographics and other characteristics of users of connected media devices, such as the iPad, iPod Touch and devices running on Google’s Android software. Initial research indicates that Apple’s iOS platform, which resides on iPhones, iPads and iPod Touches, has a combined platform reach of 28.9 million users in the five European markets, outreaching the Android platform by 116 percent.

“comScore is excited to offer insights about the comprehensive mobile ecosystem, including connected media devices, such as the iPad,” said Jeremy Copp, comScore vice president of mobile in Europe. “This new data set is part of our MobiLens service and enables our clients to understand the detailed demographic and behavioural attributes of connected media device users.
