We simply don’t know why more news organizations can’t do an adequate job of explaining the limitations of observational studies – most notably, that they can’t prove cause and effect.
Yes, they can show strong associations. But they can’t prove cause and effect.
NBC Nightly News, as one example recently, inadequately explained the latest suggestion that coffee consumption can lower the risk of prostate cancer. In the anchor lead, Brian Williams framed this as another case of flip-flopping science, lightheartedly talking about what they say about “all those medical studies…if you don’t like the findings, wait for the next study.”
The story seemed puzzled at how the same “lab” 30 years ago reported that coffee was linked to an increase in pancreatic cancer. NBC said the researchers later said they got it wrong. This time – with the prostate cancer link – they say they got it right. Read more »

Researchers from the University of Calgary have shown that doctors can make a stroke diagnosis using an iPhone application just as accurately (and faster) than they can on a traditional computer. In a study recently published by Journal of Medical Internet Research, two neuro-radiologists looked at 120 consecutive noncontrast computed tomography (NCCT) scans and 70 computed tomography angiogram (CTA) head scans. One used a diagnostic workstation and the other using Calgary Scientific‘s ResolutionMD Mobile app. The study results showed that using the ResolutionMD app is between 94%-100% accurate in diagnosing acute stroke, compared to a medical workstation.
In addition to accurately diagnosing a stroke, the app was also praised for its ability to handle a large number of images seamlessly and to detect subtle, but potentially critical findings in CT scans. Moreover, the mobile nature of the app gives doctors the ability to analyze and diagnose strokes from practically anywhere. Read more »

In an article filled with speculation, misinformation and broad sweeping generalizations, the Wall Street Journal does its damned best to make the birth control pill seem to be the worst thing to have happened to modern civilization, implying that by interfering with ovulation, the pill impairs our natural ability to choose a mate, causes women to choose less masculine partners and then stray from them, and makes us pick genetically similar rather than dissimilar mates.
Women on the pill no longer experience a greater desire for traditionally masculine men during ovulation….Researchers speculate that women with less-masculine partners may become less interested in their partner when they come off birth control, contributing to relationship dissatisfaction…That could prompt some women to stray, research suggests. Psychologist Steven Gangestad and his team at the University of New Mexico showed in a 2010 study that women with less-masculine partners reported an increased attraction for other men during their fertile phase.
“Less masculine” men. What the heck does that mean? Less hairy? Less into sports? Less violent? Not into Nascar or big trucks?
How about more likely to engage in conversation? More likely to care about their partner’s satisfaction in bed than their own? More likely to accept a woman having a career? Read more »

A new analysis in the American Journal of Preventive Medicine, “The Public’s Response to the U.S. Preventive Services Task Force’s 2009 Recommendations on Mammography Screening,” included a content analysis of news stories and social media posts around the time of the USPSTF announcement. The authors report:
“Of the 233 newspaper articles, blog posts, and tweets coded, 51.9% were unsupportive, and only 17.6% were supportive. Most newspaper articles and blog posts expressed negative sentiment (55.0% and 66.2%, respectively)….The most common reasons mentioned for being unsupportive of the new recommendations were the belief that delaying screening would lead to later detection of more advanced breast cancer and subsequently more breast cancer-related deaths (22.5%) and the belief that the recommendations reflected government rationing of health care (21.9%).
…
These results are consistent with previous studies that suggest a media bias in favor of mammography screening.”

Tweet_Fit is an amazing idea that is similar in nature to Kickbee. Here are the details:
Developed by a UK design student, the connected gym accessory attaches to the end of a standard dumbbell and sends updates to your Twitter account when you start and stop your workout. Take it offline and it guides you through the perfect curl. Tweet_Fit’s designer points out that it offers a novel way for trainers to keep track of their clients, and can be used to spur healthy competition between friends.
