He could also leverage his experience working with both parties in the Senate to push through legislation.

Postdocs under pressure
Long hours and a lack of job security, combined with workplace bullying and discrimination, are forcing many postdocs to consider leaving science — despite scientific successes. “I published papers but I wasn’t happy,” says Adrian Cazares, a postdoctoral researcher in computational microbiology. “[Postdocs] are under so much pressure all the time. We take it to every part of our lives. It really started to affect my mental health.” Nature’s inaugural survey of postdoctoral researchers reveals that nearly one in four respondents said they had experienced discrimination or harassment during their current postdoctoral stint — most from their supervisor or principal investigator.
Contraceptives research needs a reboot
Whether because of side-effects, stigma, lack of access or other issues, currently available methods of contraception are not doing the job: around 40% of pregnancies globally are unintended.

They recommend ways to reinvigorate R&D and “move from methods that women tolerate to those that actually satisfy their needs”.
