In 2019, the U.S. Food and Drug Administration went after Valley Processing, Inc. of Sunnyside, Washington, along with the company’s owner and president, Mary Ann Bliesner, due to inorganic arsenic and patulin toxins at levels that can pose health risks to consumers. Arsenic can be found naturally in many fruits, of course, a known science fact to everyone but Dr. Oz, but at high doses can be harmful.
A new paper claims that people vaping instead of smoking are putting their hearts at risk but their study does not show that. Instead, they mixed chemicals in Petri dishes with heart cells and used mice
. Both of those are fine exploratory experiments but they are scientifically invalid to make the conclusions the authors make in their press release
A lot has changed since the age of dinosaurs hundreds of millions of years ago. Humans didn't exist and dinosaurs are gone. Yet crocodiles are still here and, unlike humans, have not evolved much by comparison.
They even look similar to ones from the Jurassic period some 200 million years ago. A new study
find that it's due to a 'stop-start' pattern of evolution, governed by environmental change. This pattern of evolution known as "punctuated equilibrium" is generally slow, but occasionally means faster evolution because the environment has changed. This new research suggests that their evolution speeds up when the climate is warmer, and that their body size increases.
An American might ask if the mayonnaise is spicy while an Asian will warn them they only think they want the hot sauce on Asian food. A woman is more likely to be better at detecting bitter tastes than men.
The difference is not cultural, that some people are timid when it comes to food, is it anatomical. A new study found that Danes aren't quite as good as Chinese at discerning bitter tastes - and the reason is biology. So if you are more sensitive to the bitter taste found in broccoli, Brussels sprouts and dark chocolate, you now know why.
Smoking is on the decline, and that's a good thing. The evidence is clear that smoking kills. But what about tobacco? A few years ago groups like the U.S. Centers for Disease Control began to suggest nicotine was as harmful as smoking; meaning it was not the smoke at all. There was no evidence of that, it was only epidemiological correlation.
It's well-known that infectious disease mitigation worksl if people voluntarily follow the rules and guidelines of experts but what has happened instead is resentment of what some perceive as social authoritarian decision-makers calling the shots.
What would be better for everyone at risk of respiratory distress from COVID-19 is understanding why and how avoiding social contact and regular hand washing will help. Government can mandate things but we may be getting less adherence to guidelines because it is top-down rules, and in the case of some politicians hypocrisy after issuing them, rather than personal commitment.
It has been clear for a while that, at least in the U.S., the only way out of the coronavirus pandemic will be through vaccination. The rapid deployment of coronavirus vaccines is underway, but how many people need to be vaccinated in order to control this pandemic?
I am a computational biologist who uses data and computer models to answer biological question at the University of Connecticut. I have been tracking my state’s COVID-19 epidemic with a computer model to help forecast the number of hospitalizations at the University of Connecticut’s John Dempsey Hospital.
If you believe the Chinese government, they've had basically no meaningful COVID-19 deaths since March. I'd also like to sell you a wet market in Wuhan. Believing a dictatorship that has routinely lied has been disastrous. It was disastrous for the reputation of the World Health Organisation, who claimed no travel should be curtailed and that the virus could not spread from human to human because China told them that, it was disastrous for the doctor who exposed the Wuhan cover-up (he became dead), and it was disastrous for the world economy, which could take a decade to recover.
It may be harming trust in epidemiologists and peer review as well.
Everybody would agree that 2020 was a difficult time for all of us - the pandemic forced on us dramatic changes in our way of living, working, and interacting with one another; and let's leave alone the horrible, avoidable death toll that came with it. Notwithstanding, for some reason it was a productive year for me, and one which has potentially paved the ground for an even more productive future. Below I will summarize, if only for myself, the most important work milestones of the past year, and the ones that lay ahead in the forthcoming months. But I will also touch on a few ancillary activities and their outcome, for the record.
