Whether you use it or not, better public transit makes your commute better A surprisingly small drop in cars on the road can dramatically ease congestion, and public transit is one way to get there.

Moderna says FDA will now consider its new mRNA flu shot after initial refusal Moderna announced the change Wednesday, about a week after revealing that the FDA’s vaccine chief was refusing to review the new vaccine, made with Nobel Prize-winning mRNA technology.

Fighting for everything is exhausting, but at least it can move the needle.

Study Finds Ocean Impacts Nearly Double Economic Cost of Climate Change The β€œblue” social cost of carbon provides a more complete measure of the monetary harm caused by global climate damages…

This sentence floored me - "Until now, the ocean was largely overlooked in the standard accounting of the social cost of carbon"

Critical work from my colleague Kate Ricke.

Franzi Schimmer captured this Grizzly bear in Brooks Falls, Alaska just floating along, tippy-tapping down the river, browsing the salmon.

Prior to hibernation, up to 40% of a bear's body mass is fat, which is less dense than water (~0.9 g/cm^2), so the murder-monster is also a floaty-boaty.

Earliest recorded use of zero is centuries older than first thought | The concept and associated value of the mathematical symbol β€˜zero’ is used the world over as a fundamental numerical pillar. However, its origin has until now been one of the field’s greatest

Also - zero. Try doing STEM without the concept of zero. (Appeared in artifacts from Babylonians, Mayans, but in terms of math, seems to be Indian. www.ox.ac.uk/news/2017-09...)

Honestly, my husband gave me one to use at home. It is not only deeply satisfying to use, but maybe also helps with typing strain. He also put in rainbow backlighting under the keys.

I mean, kind of, if she was a voice I thought people trusted on scientific topics?

My opinion is predicated on hoping that non-academics gain knowledge about (& ideally benefit from) scientific findings. If their priors came from somewhere else, it's helpful to know that starting point.

Totally see your overarching point, but perhaps it's because the author was Michael Pollan whose Omnivore's Dilemma was *wildly* influential? IMHO it's important for scientists to know what people outside the lab read and think about the topics we study.
