I'm excited to share our new scientific adventure with Benny Chefetz, Evyatar Ben Mordechay, and Moshe Shenker to study the metabolism of pharmaceuticals in plants and humans. We’re grateful to BSF for their support and excited to deepen the collaboration between UCSF and HUJI through this research.

Do corporations actually have more control over your health than you?
From the food on supermarket shelves to the air we breathe, large companies exert a greater impact on our health than we might realise, argues health scientist Tracey Woodruff

Now we know that if a study is funded by the meat industry, it is 4 times more likely to conclude that red meat has positive or benign effects on cardiovascular disease risk. NIH should fund nutrition scientists so they can stop working for the food industry. ajcn.nutrition.org/article/S000...

Experimental research on the link between unprocessed red meat and cardiovascular

Dear Republicans,
Cutting science budgets has not historically been a Republican thing. For example, Lincoln created the National Academy of Sciences. Eisenhower's term increased the science budget 366%. Gerald Ford, +15%; George H. W. Bush, +30%; George W. Bush, +54%.
Just sayin’.

Cutting the budget of NASA by 50% will not only have 0 impact on the federal budget, it will also put America in the back seat, while other countries are taking the wheel. The same applies to EPA and NOAA; all three agencies founded by Republican Presidents.

I agree. I believe RFK Jr and the MAHA movement genuinely want to improve public health, but it’s not going to work if on the one hand we are banning food dyes, while on the other we are allowing manufacturers to release toxic chemicals in the environment. At best, this will be a fruitless endeavor.
Thanks for this. 4 sure there are many many toxic chemicals in food, and water and air. I agree about wanting to control our environment. But I also know that unless the government does its job - we will still be exposed to toxic chemicals no matter what.
right now that's not looking so good
