Six of the nine Nobel Prize winners this year work in the U.S.

Trump administration uses taxpayer dollars to blame Democrats for government shutdown Federal employees across the government reported seeing similar messages. Experts say the messages may violate ethics laws meant to keep partisan politics out of day-to-day governing.

Keep 'em separated Dexter Holland, the lead singer of the punk-rock band The Offspring, has a lot of different interests. One of them is biology.

The simple machine that visualised atomic orbitals In 1931, Harvey Elliott White developed a device that traced out the shapes of electron clouds by approximating solutions to the SchrΓΆdinger equation

In the early days of quantum chemistry, before we had computers to calculate the shapes of electron orbitals, one man invented a mechanical machine that simulated their shapes. My latest column for @chemistryworld.com

The United States stands at the brink of one of the most productive eras in cancer research.
Decades of steady federal investment have driven survival rates up from 49% in the 1970s to nearly 70% today. Breakthrough vaccines, targeted therapies, and less toxic treatments are finally within reach.

If RFK Jr. doesn’t resign, physicians should join a limited strike If Kennedy doesn’t resign, physicians should join a limited strike. Desperate diseases call for desperate measures.

A clear inference is that Trump, Vance, Rufo et al. are working to ensure that the PRC is the undisputed world leader in science and technology. Why they would do that, I leave as an exercise for the reader.

It doesn’t matter if you feed your kids organic foods, MAHA moms.

It doesn’t matter if you lift every day, bro.

It doesn’t matter how many supplements you consume.

When polio, diphtheria, measles, mumps, and whooping cough come a calling, all that matters is if you are vaccinated or not.
