When people see labels or menus listing the calories in their food, it doesn't change their consumption in any way beyond what experts call "statistical wobble." About two fewer almonds worth of calories per meal. But two almonds over time can add up to a lot.

That's the conclusion in the data of a systematic review by The Cochrane Collaboration. The team of academics reviewed 25 papers which discussed the impact of calorie labeling on consumption and found a minute reduction in the foods selected - about 11 calories.
Science is always looking for new ways to protect plants and the environment. In Hawaii, for example, when their staple papaya was under attack by aphids that transferred the "papaya ringspot virus" to plants, legacy breeding and pesticides did not work. A gene gun sending in a GMO did.(1) In the Wall Street Journal, I discussed how a non-corporate, free modification by academics could save the American Chestnut from the natural blight that had devastated billions of trees.(2)
With Burns Night this weekend,  Scotland will celebrate its heritage. In the First Among Equals country to the south that controls them, Scottish accents used to mean trouble. Now, it is the sound of safety for both English men and women.

A new study finds that the English, even some Welsh and Scottish, associate a "working-class" accent with criminal behavior. In a jury trial, that could have serious ramifications, but it likely also matters before that. Arrests and voice identification, for example. You're more likely to be one of The Usual Suspects(1) if your accent is criminal.
Doctors who would never tell a patient to smoke cigarettes in moderation, they are a legitimate class 1 carcinogen, oddly say just that about an identical class 1 carcinogen, alcohol, and as recreational marijuana has become legal they have given it the same umbrella.

Legal or not, marijuana is a drug just like alcohol, and it includes the toxic smoke of cigarettes.

I am not a social authoritarian progressive so I won't tell you how to behave just because my health insurance premiums went up so 50,000,000 others could get it cheaper, but you absolutely should not be smoking marijuana around kids. It ain't the 1980s, hippie.

Have you purchased organic food and wondered what the chemical is that you need to wash off?

Those are alkaline wax-based coatings, designed to preserve food so it looks nice longer. Just like conventional growers use. But chemical wax coatings made including olive bud oil don't prevent fungi and bacteria common in organic food, and a new program would like to change that.
The Biden administration recently issued a new report showing causal links between alcohol and cancer, and it's about time. The link has been long-known, but alcohol carcinogenic properties have been waved away with 'use in moderation' rhetoric. We don't tell young people to use cigarettes 'in moderation', even though nicotine doesn't cause cancer, only cigarettes smoke does, so that alcohol has gotten political free pass shows science is always second to politics.
