Climate Change Study Strengthens Link to Human Activities

Computer Models, Satellite Data Reveal Clearest Evidence Yet of Human Influence on Changing Temperatures

New research shows some of the clearest evidence yet of a discernible human influence on atmospheric temperature.

Published online in the Nov. 29 early edition of the Proceedings of the U.S. National Academy of Sciences, the study compared 20 of the latest climate models against 33 years of satellite data. When human factors were included in the models, they followed the pattern of temperature changes observed by satellite. When the same simulations were run without considering human influences, the results were quite different.

“We can only match the satellite record when we add in human influences on the atmosphere,” said Michael Wehner, a research scientist at Lawrence Berkeley National Laboratory (Berkeley Lab) Computational Research Division and a coauthor of the article, which involved colleagues from 16 other organizations and was led by Benjamin Santer, an atmospheric scientist at Lawrence Livermore National Laboratory (LLNL).

First Measurements Made of Key Brain Links

Science

Until now, brain scientists have been almost completely in the dark about how most of the nonspecific thalamus interacts with the prefrontal cortex, a relationship believed to be key in such fundamental functions as maintaining consciousness and mental arousal. Brown University researchers performed a set of experiments, described in the Journal of Neuroscience, to explore and measure those circuits for the first time.

PROVIDENCE, R.I. [Brown University] — Inside the brains of mice and men alike, a relatively big football-shaped region called the thalamus acts like a switchboard, providing the prefrontal cortex, the part that does abstract thinking and decision-making, with most of its information. The thalamus’s responsibility even includes helping the prefrontal cortex to maintain consciousness and arousal. (more…)

Student Startup Aims to Prevent Traffic Jams

Technology

Winners of the second annual Imagine Cup Grants program, part of Microsoft’s YouthSpark initiative, include student startups aiming to eliminate traffic jams and bring cheap, effective ways to diagnose childhood pneumonia.

MOUNTAIN VIEW, Calif. — Dec. 4, 2012 — Traffic jams typically produce little more than frustration, profanity, and CO2. Four years ago, though, they happened to give Christian Brüggeman an idea.

He was sitting in a London Starbucks with a friend and fellow computer science student. As they chatted, they noticed that one street outside was choked with cars while another was practically empty.

They wondered why drivers weren’t taking advantage of every possible route. If cars could be directed along less-congested roads, wouldn’t that prevent back-ups before they began? (more…)

Multiple Media Use Tied to Depression, Anxiety

Health

Using multiple forms of media at the same time – such as playing a computer game while watching TV – is linked to symptoms of anxiety and depression, scientists have found for the first time. (more…)

Women with Sleep Apnea Have Higher Degree of Brain Damage than Men, UCLA Study Shows

Health

Women suffering from sleep apnea have, on the whole, a higher degree of brain damage than men with the disorder, according to a first-of-its-kind study conducted by researchers at the UC LA School o f Nursing. The findings are reported in the December issue of the peer-reviewed journal SLEEP. (more…)

NASA Mars Rover Fully Analyzes First Soil Samples

Science

PASADENA, Calif. – NASA’s Mars Curiosity rover has used its full array of instruments to analyze Martian soil for the first time, and found a complex chemistry within the Martian soil. Water and sulfur and chlorine-containing substances, among other ingredients, showed up in samples Curiosity’s arm delivered to an analytical laboratory inside the rover. (more…)

New Study on Physician Online Behaviors Shows Health Care Professional Sites Reach 4 out of 5 Physicians, While Electronic Medical Records Show Highest Engagement

Technology

More Than Half of Physicians Show Interest in Using Mobile Devices and Tablets at Work

RESTON, VA, December 3, 2012 – comScore, Inc., a leader in measuring the digital world, today released new findings from a study based on data generated by the comScore/Symphony Health Care Professional (HCP) Measurement Solutions offering, which provides insight into the actual online behavior of physicians with regard to health-related categories, and the Physician Mobile Survey, a survey of physicians’ attitudes toward mobile devices and tablets in the workplace. Based on a longitudinal study of a permission-based panel of 1,000 U.S. physicians, the study showed that HCP Content websites such as Medscape.com, which provide content or services catering specifically to physicians, reached the highest percentage of physicians (81 percent) in comparison to other types of health sites. However, Electronic Medical Records sites such as Allscripts.com showed higher engagement as physicians have begun to use these sites to replace paper record-keeping. The study also revealed that although computers are still the most often used device to go online at work by physicians, more than half of physicians expressed interest in using mobile phones and tablets in the workplace.
