Guidelines for Prostate Screening Widely Ignored, Study Finds

2008 recommendations from federal task force had no impact

New research confirms that the controversial decision by Warren Buffett – the 81-year-old CEO of Berkshire Hathaway – to undergo a blood test screening for prostate cancer despite his age is hardly unusual. Despite recommendations in 2008 from the United States Preventive Services Task Force against testing for prostate cancer in men aged 75 years or older, almost half of men in that age group continue to get screening tests.

In 2005, before the recommendations were released, 43 percent of men age 75 and above elected to take the prostate-specific antigen (PSA) test. In August 2008, the Task Force stated it “recommends against the service,” arguing “there is moderate or high certainty the service has no net benefit or that the harms outweigh the benefits.” (more…)

NASA Tests GPS Monitoring System for Big U.S. Quakes

PASADENA, Calif. – The space-based technology that lets GPS-equipped motorists constantly update their precise location will undergo a major test of its ability to rapidly pinpoint the location and magnitude of strong earthquakes across the western United States. Results from the new Real-time Earthquake Analysis for Disaster (READI) Mitigation Network soon could be used to assist prompt disaster response and more accurate tsunami warnings.

The new research network builds on decades of technology development supported by the National Science Foundation, the Department of Defense, NASA and the U.S. Geological Survey (USGS). The network uses real-time GPS measurements from nearly 500 stations throughout California, Oregon and Washington. When a large earthquake is detected, GPS data are used to automatically calculate its vital characteristics, including location, magnitude and details about the fault rupture. (more…)

Study Shows That, In Restaurants, Race Matters

A new study from North Carolina State University shows that more than one-third of restaurant servers discriminate against African-American customers.

“Many people believe that race is no longer a significant issue in the United States,” says Sarah Rusche, a Ph.D. candidate in sociology at NC State and co-author of a paper describing the study. “But the fact that a third of servers admit to varying their quality of service based on customers’ race, often giving African-Americans inferior service, shows that race continues to be an issue in our society.” (more…)

UA student Jason Xu has been recognized by the College of Science for his undergraduate research.

Wuhan, China and Tucson, Ariz.: These cities are thousands of miles apart, but they have one commonality – University of Arizona student Jason Xu.

A Chinese native and mathematics senior in the Honors College, Xu was selected as the recipient of this year’s Excellence in Undergraduate Research award by the UA College of Science at its Galileo Circle reception event.

The award “is a huge honor and means a lot to me. I feel really good to be representing the math department,” Xu said. (more…)

For treatment of vocal fold disorders, UD researchers look to insect protein

A one-inch long grasshopper can leap a distance of about 20 inches. Cicadas can produce sound at about the same frequency as radio waves. Fleas measuring only millimeters can jump an astonishing 100 times their height in microseconds. How do they do it? They make use of a naturally occurring protein called resilin.

Resilin is a protein in the composite structures found in the leg and wing joints, and sound producing organs of insects. Highly elastic, it responds to exceptionally high rates of speed and demonstrates unmatched resilience after being stretched or deformed. (more…)

For Display Ads, Being Seen Matters More than Being Clicked

New Research from Pretarget and comScore Suggests that Buyer Conversion is More Highly Correlated with Ad Viewability and Hover than with Clicks or Gross Impressions

SAN FRANCISCO and RESTON, VA, April 24, 2012 – comScore, Inc., a leader in measuring the digital world, and Pretarget, the intent targeting company, today released results of an online advertising study which found that ad viewability and hover time are more strongly correlated with conversions (defined as purchases and requests for information) than clicks or total impressions.

“Your ad being seen matters more than your ad being clicked – if you have a back-end conversion metric,” said Pretarget Founder Keith Pieper. “After all, what good is an ad that can’t be seen? It’s intuitive that an ad must be seen to make an impact, and it’s even more intuitive than someone hovering and engaging with an ad might convert, even absent a click.” (more…)
