Do you prefer to rise early with the lark or stay up late with the owl? Your preference turns out to be partly decided by your genes. Our genetic study of nearly 700,000 people has revealed new insights about the genetics of chronotype – our preference to rise early or sleep late – and how it influences our mental and physical health.

Though our guts contain a trillion bacteria in various compositions, it's become popular to claim any detectable change is a bad thing. Unless it is to sell yogurt, where no detectable change is regarded as a probiotic good thing.

Now even at the nano- level. A new study claims ultra-small particles adhere to intestinal microorganisms, thereby affecting their life cycle as well as cross talk with the host. Nanoparticles’ binding inhibits the infection with Helicobacter pylori, a pathogen implicated in gastric cancer and the authors hope this could the development of potential 'probiotic' nanoparticles for food. Homeopaths are cheering.

Nothing killed science culture more than Spock from the 1960s television show "Star Trek." He was wildly popular because he was so logical and reasoned. Emotions did not enter into his decisions. Scientists flocked to that mystique and so a whole generation of scholars sought to be dispassionate and data-driven in their interactions with the public.

In 2015, I predicted that someone was going to end up in the hospital due to overdoses on supplements.

But don't you always say they are useless placebos? a friend asked.

No, they are not all placebos, but products sold as supplements that do something are either actual drugs, like kratom, and thus should be regulated as drugs, they are useless placebos adulterated with actual drugs, like many Internet erectile dysfunction and diet pills, or they are useless in normal doses but toxic at high levels. 

Like Vitamin D.

Like " I had insomnia last night" and "I am so OCD", medical terms often become colloquial. So it is with people who say they had a "stomach flu."

There are stomach virusus, but what many people commonly call “stomach flu” isn’t flu at all. "Flu" is short for influenza, and that is respiratory so it involves lungs, not the stomach. What people call a stomach flu is instead viral gastroenteritis. It could be rotavirus, norovirus, adenovirus or something else, and could have been through tainted food.

As the world's most powerful economy, we read a lot about how America needs to do more to use cleaner energy, and less of it. 

Chicken eggs are already used for growing viruses that are used as vaccines, such as the flu jab but science is going one better; chickens that are genetically modified to produce human proteins in their eggs as part of the egg white.

A new study found the drugs work at least as well as the same proteins produced using existing methods and high quantities of the proteins can be recovered from each egg using a simple purification system and there are no adverse effects on the chickens themselves, which lay eggs as normal.

One to two percent of people have celiac disease, and the first thing they will tell you is that it is not a fad diet, no matter how many books or Dr. Oz segments tout gluten-free. To celiac patients, it is like poison and the replacements for gluten often contain extra sugar, extra fat, hydroxypropyl methyl cellulose and xanthan gum.

Science may soon be able to help. Gluten is a mixture of glutenin and gliadin proteins, which build a network that gives wheat bread itsproperties and quality. Most gliadins and part of the glutenins contain immunogenic epitopes, which are the actual trigger of the immune reaction.

Anti-science activists are having a field day on social media, happy that a poorly designed study can let them claim that human sperm is being damaged by modern pesticides, even though the study found nothing of the kind. 

The Doomsday Clock, a public relations stunt created by Bulletin of the Atomic Scientists (1) remains stuck at two minutes until midnight. Just like it was in 1953, the height of the Cold War, when school kids did drills about hiding under desks and everyone built bomb shelters.

Today their worry is still nuclear bombs, they assure us, but also global warming and President Trump, and that is why they have solemnly announced that the Doomsday Clock is still at 2 until midnight, with midnight being the End Of The World.
