If people want to believe that our ancestors were riding around on dinosaurs or that the protracted, increasing, and devastating warming of the Earth is just nature doing its thing - I guess I feel I have more useful battles to fight.
'Natural' is a word that has become unmoored by its meanings. If you go into a vitamin shop, things are natural, and people look at that, and they think it's good. It's no different than any other thing you swallow.
Meat supplies a variety of nutrients - among them iron, zinc, and Vitamin B12 - that are not readily found in plants. We can survive without it; millions of vegetarians choose to do so, and billions of others have that choice imposed upon them by poverty.
Lyme disease is the most commonly reported tick-borne illness in the United States, and the incidence is growing rapidly. In 2009, the C.D.C. reported thirty-eight thousand cases, three times more than in 1991. Most researchers agree that the true number of infections is five to ten times higher.
There are many theories about the best way to remove excess carbon from the atmosphere - some are ludicrous, others are at least worth study. The most commonly discussed plan is to lace the sky with reflective chemicals.
The numbers matter: underreporting of Lyme disease obscures the true burden of the illnesses, on individuals as well as on health-care systems. It also makes it harder to convince Congress to fund research.
The Centers for Disease Control and Prevention has established highly specific criteria for the diagnosis of Lyme disease: an acknowledged tick bite, the appearance of a bull's-eye rash, and, for those who don't live in a region where Lyme is common, laboratory evidence of infection.
The best way to deal with climate change has been obvious for years: cut greenhouse-gas emissions severely. We haven't done that. In 2010, for example, carbon emissions rose by six per cent - the largest such increase on record.
Newspapers and magazines have been valuable to us precisely because they apply filters to information, otherwise known as editing, and often the Internet seems valuable for exactly the opposite reason: You can get your news without a filter.
Much of modern molecular biology and microbiology has been based on the effort to decipher the basic code of life, which is made up of four nucleotides: adenine, thymine, cytosine, and guanine.
Until the Nineteen-Eighties, when Deng Xiaoping designated the area as China's first special economic zone, Shenzhen had been a tiny fishing village. Suddenly, eleven million people appeared, seemingly out of nowhere; factories sprang up, often housed in hastily constructed tower blocks.
If left untreated, Lyme disease can be crippling, yet it is a difficult illness to contract: a tick needs to attach itself to your body for at least twenty-four hours. Even then, two weeks worth of commonly prescribed antibiotics will kill the bacterium.
For decades, Barbara Walters has been described as a broadcast pioneer - and with good reason. In 1974, Walters became the first female host of the 'Today' show. In 1976, she became the first woman to serve as a network-news anchor. In 1984, she moderated the first presidential debate between Walter Mondale and Ronald Reagan.
Deliberately modifying the earth's atmosphere would be a desperate gamble with significant risks. Yet the more likely climate change is to cause devastation, the more attractive even the most perilous attempts to mitigate those changes will become.
Any group that intends to sell laboratory meat will need to build bioreactors - factories that can grow cells under pristine conditions. Bioreactors aren't new; beer and yeast are made using similar methods.
To suggest that organic vegetables, which cost far more than conventional produce, can feed billions of people in parts of the world without roads or proper irrigation may be a fantasy based on the finest intentions. But it is a cruel fantasy nonetheless.
The passengers in our microbiome contain at least four million genes, and they work constantly on our behalf: they manufacture vitamins and patrol our guts to prevent infections; they help to form and bolster our immune systems, and digest food.
The most blatant forms of denialism are rarely malevolent; they combine decency, a fear of change, and the misguided desire to do good - for our health, our families, and the world. That is why so many physicians dismiss the idea that a patient's race can, and often should, be used as a tool for better diagnoses and treatment.
