As we get older, we start to notice changes in our bodies and minds that we associate with aging. And we just accept them because that’s what happens when you get older. But what if we change our expectations? Can that have real effects on us? Ellen Langer has been running experiments for over thirty years that suggests it can.
It should probably come as a surprise to no one, but the number of cancer cases among 9/11 first responders and rescue workers is growing. Yes, it may not be statistically significant yet, but given that the WTC was built in the early 1970s and was full of materials known to be carcinogenic, this trend seems likely to continue.
Luckily, the government set up the World Trade Center Health Program to help these folks and they will continue to monitor and treat those affected. It’s the least we can, really.
No, it’s not one of those “name three things that don’t go together” deals, it’s a strange but true story that started with a German patient with strange symptoms that no one could figure out. But a doctor at the Centre for Undiagnosed Diseases in Marburg, Dr. Juergen Schaefer, a ‘House’ fan, recognized the symptoms from an episode featuring a patient with a deteriorating artificial joint and was able to determine he was suffering from cobalt poisoning as a result of an old pair of hip replacements. Once the metal joints were replaced with ceramic he made a partial recovery (some of the damage was permanent).
But, you ask, what about the beer? It turns out that cobalt poisoning is extremely rare, mostly confined to steelworkers (cobalt is used as an additive). But there was also another group that was affected, beer drinkers in 1960s Quebec. That’s because a brewery, Dow, added cobalt sulfate to its beer to help foam stability. Although most drinkers had no problems with the beer, very heavy drinkers ingested enough cobalt to come down with symptoms. Dow went out of business in 1997, sales never having recovered from the incident.
Om Malik, himself a diabetic, looks at Google’s Smart Contact Lenses.
While I was aware that diabetics must be aware of a number of health issues (in addition to their blood sugar levels) the recommendation against contact lenses is new to me. Diabetic health is definitely an area that could use some automation, obviously, but smart contacts aren’t the answer.
After bailing out of the approval process, 23andMe’s DNA testing kit was (technically) banned from sale by the FDA. But it’s still for sale.
Charles Seife in Scientific American says that’s not the reason you should be concerned. That’s because 23andMe’s real business isn’t medical research, it’s data collection.
Hmmm, it’s 2012 and we still don’t know what causes ‘brain freeze’?
