"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?

Patients with Werner Syndrome show early signs of aging, including grey hair and wrinkled skin. They live on average about 45 years. It affects around 1 in 200,000 people in the U.S. but in Japan it is 1 in 40,000. 

Why the difference?  That is a mystery, like much of the disease. Since the underlying mechanisms are unknown there is no real treatment or cure, but a new study found that in banana flies and C. elegans worms with the equivalent of the syndrome that the dietary supplement nicotinamide adenine dinucleotide (NAD+) prolonged life and reduced age-related diseases like cancer.

We are setting up a live streaming/video channel to do things like reviews of books, interviews, and then eventually we will do staff meetings as well.(1)

But while it was once limited to something like Facebook live, with Restream we can go out to YouTube Live, Mixer, and Twitch, all at once.(2) 

You’ll often hear about the “Ice albedo effect” as a supposed tipping point that the IPCC is ignoring. The idea is that as the Arctic ice melts, it absorbs more heat from the sun, and so warms the planet. What they ignore is that as the planet warms there are also more clouds, especially in tropical regions. This did seem a possibility in the 1980s, and Margaret Thatcher mentions it in her speech to the UN. However, you need to look at the planet as a whole, and we now know that because a warmer world has more clouds in the tropics, the overall global albedo effect is actually a cooling rather than a warming effect, helping to offset some of the global warming.

In late November 1999, a TV producer called me about an alarming report that 44,000 to 98,000 Americans were being killed each year by preventable errors in hospitals and another 1 million were being injured.

Could that be true? Based on my research, I replied, the estimate seemed low.

This is in response to a “Nature comment” Climate tipping points — too risky to bet against which is scaring people. There are no new research findings in it and nothing to overturn the IPCC's conclusions. Of course it is important to look carefully at tipping points and the IPCC has done so with its high level reviews, and examined many research papers on the topic. The IPCC and climate scientists fully appreciate the importance and significance of tipping points. The reports are saying that factually the science doesn't support them in this case for global warming at the levels of CO2 emissions considered.

This exceptionally well-preserved crinoid, Delgadocrinus oportovinum, was found on October 11, 1905, by Nery Delgado during his work mapping the geology and paleontology of Portugal. 

Crinoids are marine animals in the class Crinoidea. They are echinoderms related to starfish, sea urchins, sea cucumbers and brittle stars. Adult crinoids have a mouth located on the upper surface surrounded by feeding arms. These have feathery pinnules and are spread wide to gather planktonic particles from the water.

Let's say your Generation Z child is concerned about chemicals in your Thanksgiving meal and you want to avoid that awkward moment when they don't look up from their phones while saying "OK Boomer" as you try to explain to them that all food has chemicals.

Maybe they just don't want scientific chemicals. Maybe they want the organic kind that are healthier, according to, well, organic industry trade groups and journalists at the Mother Jones company.

So you trudge off to Whole Foods or a store you read about on a Facebook page and buy the stuff on your menu, all certified expensive. I hate to alarm you but it all has chemicals that are known carcinogens. That's right, they cause cancer.

We are headed for the next round of climate pledges in 2020. So, what do we need to do to stay within 1.5 C? This is based mainly on the new UN Emissions Gap Report 2019
