They just don't make ads like this anymore. "Guy with pince-nez" is great visual shorthand for "Authority figure."

Two recent papers about heart disease from the Cleveland Clinic are making the rounds. The studies report that red meat and eggs cause heart disease because our gut bacteria converts carnitine and choline into Trimethylamine N-oxide (TMAO), a heart disease trigger.
At Huffington Post, Chris Kresser has questions about the papers:
[W]hile at first glance the papers from Dr. Hazen's group might appear to be the final nail in the coffin for the omnivorous among us, a closer inspection of their data reveals some troubling questions. First, a study back in 1999 found that seafood generates much higher levels of TMAO than red meat, eggs, or any of the other 46 foods tested. One species of fish, halibut, produced 107 times as much TMAO as beef, and 53 times as much TMAO as eggs. If high TMAO levels cause cardiovascular disease, and eating fish increases TMAO more than any other food, we'd expect to see high rates of heart disease in people who eat the most fish. Yet that is the opposite of what research shows. In fact, some studies have found eating more fish (particularly cold-water, fatty fish like salmon) reduces the risk of heart attack by a greater margin than statin drugs!In fact, whole grains could play a role in elevating TMAO levels:
In their second paper, Dr. Hazen's team raises the possibility that the foods we eat aren't the primary driving force behind our TMAO levels, because most people are able to excrete excess TMAO that accumulates in the blood via the urine. This suggests that something else may be to blame for high TMAO. What could that be? One possibility, which the researchers themselves demonstrated in the first paper, is that differences in our gut bacteria could account for the higher TMAO levels observed in some people. They showed that those with greater amounts of a type of bacteria called Prevotella in their gut generated more TMAO after eating carnitine. And what might lead to a higher concentration of Prevotella in the gut? Ironically, previous research has shown that the people who eat large amounts of whole grains are the most likely to fit this pattern. This would suggest that a diet high in whole grains -- and not red meat or eggs -- could increase the risk of heart disease by elevating TMAO in the blood.Red Meat and Eggs on Trial Again, But Jury Is Still Out
Juha sez, "Amazingly enough, New Zealand's North and South magazine has lost in the NZ Press Council, after a homeopath filed a complaint against an article that stated: 'Homeopathic remedies have failed every randomised, evidence-based scientific study seeking to verify their claims of healing powers.'"
"Mr Stuart [a homeopath] supplied the Press Council with a letter from Dr David St George, Chief Advisor on Integrative Care for the Ministry of Health, who advises the ministry on the development of complementary medicine in New Zealand and its potential integration into the public health system. He was not speaking for the ministry in this case but offering a personal view.
Dr St George believed the statement in North & South's article arose from a misunderstanding of the Lancet study, which had compared 110 published placebo-controlled trials of homeopathy with the same number of published placebo-controlled trials of conventional medical drug treatments. He said most of the 110 homeopathy trials in that study were "randomised, evidence-based scientific studies" which demonstrated an effect beyond a placebo effect. "
Dr St George said there was no debate about whether there were scientific studies demonstrating homeopathy's therapeutic benefit but rather, whether those studies were of an acceptable methodological quality.
Turner said they intended to examine any physiological changes to people in the Eno room – pulse, blood pressure, anxiety and so on – and there was anecdotal evidence this week when a cancer patient came out and began telling Eno, not recognising him, how wonderful it was. "He wanted a copy of that room at home," said Turner. "The scientist in me says that's not very scientific but the human in me says that makes it all worthwhile.""Surgeon prescribes Brian Eno to patients"

Dave sez, "THE ZIPPER CLUB is a comic focusing on survivors of childhood congenital heart defects, written by a survivor of such a condition himself. It's on Indie-GO-Go in hopes to put out a first print run. Part of the proceeds will go to the AHA and part of the run will be distributed to pediatric cardiac care centers for the kids who will truly benefit from it."
At age 8, Cliffy Goldfarb was the recipient of an emergency heart transplant. At age 9, Cliffy is now struggling to cope with the limitations his still recovering body is undergoing, and the fact that because of this, he has trouble relating to his peers. When his mom suggests spending his summer at Camp Bravehearts, a place for kids living with heart defects like his own, he has some trepidations about going this camp for “special” kids, but soon learns his worries were all over nothing when he meets a young girl named Rosie who introduces him to a group of new friends who encourage him by showing off their surgical scars to one another and inducting Cliffy into “The Zipper Club”.
Welcome to THE ZIPPER CLUB! (Thanks, Dave!)
Thearn released a free/open program for detecting and monitoring your pulse using your webcam. The code is on github for you to download, play with and modify. If this stuff takes your fancy, be sure and read Eulerian Video Magnification for Revealing Subtle Changes in the World, an inspiring paper describing the techniques Thearn uses in his code:
This application uses openCV (http://opencv.org/) to find the location of the user's face, then isolate the forehead region. Data is collected from this location over time to estimate the user's heartbeat frequency. This is done by measuring average optical intensity in the forehead location, in the subimage's green channel alone. Physiological data can be estimated this way thanks to the optical absorbtion characteristics of oxygenated hemoglobin.
With good lighting and minimal noise due to motion, a stable heartbeat should be isolated in about 15 seconds. Other physiological waveforms, such as Mayer waves (http://en.wikipedia.org/wiki/Mayer_waves), should also be visible in the raw data stream.
Once the user's pulse signal has been isolated, temporal phase variation associated with the detected hearbeat frequency is also computed. This allows for the heartbeat frequency to be exaggerated in the post-process frame rendering; causing the highlighted forhead location to pulse in sync with the user's own heartbeat (in real time).
Support for pulse-detection on multiple simultaneous people in an camera's image stream is definitely possible, but at the moment only the information from one face is extracted for cardiac analysis
