A joke in nutrition circles is that while you once needed to be rich to be fat, now you need to be rich to be thin. Scientific progress has given us cheap food, anyone can afford to eat well, and after an existence of worrying about food availability it takes generations for culture to change to not eating as much as we can. Rich people, though, have gym memberships.

A cross-sectional study has found that head and neck injuries related to cell phone use increased steadily over a recent 20-year period.

But that may not be meaningful in a relative risk way. The sample was just over 2,500 cases from 1998 through 2017. Media will trumpet 300 percent since 2007 but that doesn't make injuries common. It just means that as phones changed from phones to messagers to full-on portable televisions and computers people are able to walk and be distracted more.

When Al Gore was Vice-President in 1994, he forced the U.S. EPA to mandate ethanol in gasoline by breaking the Senate tie in favor of environmentalists who had been pushing ethanol as 'sustainable biofuel' for decades. His vote forced gasoline manufacturers to include it despite science concerns it would drive up food prices and increase pollution. While biofuels were and are a viable field of study, the concern was that dumping money into corporate subsidies was going to hold progress back.(1)

In December, people begin to think about the new year, and that means resolutions to lose weight. Exercising is a lot of work and feeling hungry much of the time is not desirable so many will instead opt for diet plans. One popular diet is the Atkin's Diet, where natural sugars are replaced with protein, while another is the Ketogenic Diet, where sugars are replaced with fatty foods. Both seek to put your body into a metabolic state called ketosis, where elevated level of ketone bodies replace glucose.

"Epstein didn't kill himself" is a conspiracy meme that has been everywhere lately. If you are not familiar with the name Jeffrey Epstein, he was a billionaire and convicted sex offender - but as a billionaire he was connected to almost everyone in politics and culture, so when he was found dead in his jail cell, denied bail on a new charge, there began concerns someone had him killed to keep him silent.

I got an email from a young person at a university stating they were working on a research paper, and while many in the science and scicomm community are jaded about such requests - we are doing someone's homework for them, it is said - I always answer. It's a nonprofit, answering is the job.

The questions were rather specific to GMOs so I stuck to that, but of course I write about a lot more than agriculture while the rest of Science 2.0 writes about virtually every area of science.

The 5 questions I answered below and I added some more thoughts for this article:

1. Why did you create Science 2.0?
2. Why did you choose to write about GMOs?
3. What impact do you think the anti-GMO activist have on the scientific community?
