If you’ve ever needed a blood transfusion, or donated blood, you probably would have been asked your blood type. While it was once thought all blood was the same, we now know there are different types of blood, called blood groups. Transfusions between blood groups can be catastrophic, even deadly, so knowing the blood type of donors and recipients is of the utmost importance.

Our bodies contain trillions of red blood cells. Each is covered in an array of proteins and sugars, inherited from our parents, which determine our blood group. We can all be classified into group A, B, AB or O, based on which sugars coat our red blood cells.

Class-action lawsuits were making America Great Again long before it was a thing.  Attorneys actively solicit anyone involved (or maybe might be potentially involved) in a particular event, and get them all in one place to file a chunky lawsuit. 

This gives a little fuel to the lawsuit for obvious reasons, and is appealing to the “victim(s)” because they do not have to shop out an attorney, and they get to commune with others that were also “victimized”.  All they have to do is sit back and collect the check. 
There are multiple food fads trying to catch on per year but as the saying goes in science, if one epidemiology study counted, everything would cause or prevent cancer.

One long-held epidemiology belief is that the more vegetables you eat, the healthier your heart will be.  While vegetarians and animal activists tout such claims, the actual evidence is not clear. In recent decades we've been told bacon, butter and red meat all cause heart disease. But the same groups scaremongering food have also claimed that coffee causes breast cancer, that cell phones cause all kinds of cancer, and that BPA can be an endocrine disruptor, even though they are biological and toxicological impossibilities. 
You might think that after the November elections, the last group anyone will listen to for guidance on the American public are partisan pundits. But they are still lobbying for an alternative result, now saying that if President Trump wants to honor his commitment to repealing the The Patient Protection and Affordable Care Act (Obamacare) while allowing more coverage, better benefits, and lower costs, the only choice is a Single Payer system; socialized medicine.

They list now-famous pretend money, the same optimistic estimates that led to the Obamacare system being financially viable, savings of $504 billion annually on health care bureaucracy and profits.

It’s not hard these days to find stories in the popular media about the presence of various chemical contaminants in our environment.  Included in this genre are stories about trace levels of chemicals in common consumer products, in the air we breathe, and in the water we drink.  Almost inevitably the stories suggest that even minor exposures are harming our health.

Over the past 15 years or so sitting has been linked with cancer, heart disease and diabetes and even

Women who received a health scare in the form of a false positive result from a screening mammogram were more likely to delay or even forgo the next mammogram than women who had a correct negative result.

A false positive result from a screening mammogram often leads to emotional, physical, and economic stress, though false positives are an expected part of proper medical care. For this study, the authors obtained data for women who received mammography screening through a large health care organization with multiple facilities in the greater metropolitan Chicago area. Among the 741,150 screening mammograms from 261,767 women included in the analysis were 12.3 percent that yielded a false positive result; the remaining 87.7 percent yielded true negative results.
If you sip a beer when you are a teenager, are you going to become a raging alcoholic? You are according to the logic of anti-smoking activists who won the war on cigarettes and need a one place to use their army - and their funding.

Cigarette smoking has plummeted, which is what we have all wanted, and part of the reason for that is smoking cessation tools, like gums, patches, smokeless tobacco and things like e-cigarettes. Those are also used for harm reduction; smoking is as uncool as can be these days, so from a health point of view every cigarette not smoked is a win. They work because nicotine is addictive, like caffeine and alcohol, so providing that stimulus without the toxins is good.
Between 2012 and 2015, the number of chemical burns to the eye associated with laundry detergent pods increased more than 30-fold among preschool-aged children in the US, according to a new analysis, but don't fall prey to the scaremongering that will be done by CNN and PBS.

Detergent pods are dissolvable pouches containing enough laundry detergent for a single use - they lead to less waste because  the amount used is precise. That's good for the environment. But harried parents are being given one more thing to be terrified about, and academics are blaming "candy-like appearance."
