The way I convert has always been to start from:
0 C = 32 F
Then, every +10 C is +18 F

So,
10 C = 50 F
20 C = 68 F
30 C = 86 F
(+5 C is +9 F for filling in increments between when needed)

Adaptive landscapes unveil the complex evolutionary path from sprawling to upright forelimb function and posture in mammals The ‘sprawling-to-parasagittal’ postural transition is a key part of mammalian evolution from non-mammalian synapsids. This study uses evolutionary adaptive landscapes to reveal parasagittal postures ...

I'm so excited to share my latest paper out now! How did the ancestors of mammals make the switch from sprawling to upright, taking over the world in the process? Spoiler alert; it's complicated! journals.plos.org/plosbiology/...

1. Knowledge of what’s local (and how to care for it)
2. Not having any areas that I control

The motivation to figure out the first would be there if the second wasn’t the main barrier

Thank you, Bouwe!

Today, my successfully defended dissertation was accepted by ProQuest in its final, correctly-formatted version! What a journey it has been to get to this point. #PhDone

His training schedule in this interview:

-Start training day at 9:30am
-Workout, lift, recovery
-Sleep all afternoon
-Wake up at 10pm
-Work UPS until 4am
-Sleep 3 hours, wake up, repeat

It's still early in the season, but he's run the fastest time in the world so far this year

YouTube video by CITIUS MAG Jacory Patterson Talks Job At UPS + Racing Unsponsored After 43.98, 2nd In Long Sprints At GST Miami

Biggest story IMO from the first two meets of Grand Slam Track so far:

Jacory Patterson, unsponsored athlete and UPS driver, wins the 400 in Miami this weekend becoming the 26th fastest guy in history (43.98). Finishes 2nd in the Slam, takes home $50k. That's life changing

🚨 HISTORY LOADING... 🚨

Nike has announced that on June 26th, triple Olympic 1500m champion and mile world record holder Faith Kipyegon will attempt to do what no woman ever has: run a sub-4-minute mile.

Kipyegon currently holds the WR at 4:07.64.

Not-periodizing means leaving a little bit of fitness on the table, for example, if you have a goal marathon you are working towards, but it’s pennies compared to other stuff (like total volume)

Others have touched on this, but it depends on goals. Periodization is mostly for elites (at least college level) to optimize peaking for a particular race. For most folks (especially those running for health/fitness), better to do what keeps you motivated with down weeks as the body needs it.

A photo of a pygmy possum clinging to a human thumb. The animal has a curly pink tail and somewhat resembles a light brown mouse.

Behold the western pygmy possum! This dainty marsupial typically weighs ~0.5 oz (14 g)—that's about as much as a AA battery! It inhabits treetops in forests throughout parts of Australia. As a nectarivore, it mainly feeds on plant nectar.

Absolutely love this illustration!

A multi-tasking #platypus: chewing & scratching at the same time.
When #platypuses dive, they cram their cheek pouches full of food, to chew when they surface. Platypuses don't have teeth (they wear down too easily): they've replaced them with ever-growing horny ridges.

At this point, the dissertation acknowledgements is definitely giving a shout out to coffee growers, coffee roasters, and the family Rubiaceae for giving rise to such a fine genus. Maybe also Ethiopian farmers for cultivating it and the Ottomans for bringing it to Europe if I feel particularly bold.

Cannot give this film enough praise! So excited to see that it won the Oscar for Animated. Absolutely love the detail they put into animal movement and personality.

How do you measure what isn't there?

Elska did a fantastic job leading this paper on how we can measure the volume of changing, 3D spaces inside XROMM skeletal animations. And, importantly, how good are those volume measurements?

As somebody who grew up with competitive running just a few miles down the road from Grand Blanc, I can't overstate how exciting it is to watch Fisher's success. Never in my life did I think an American would hold TWO middle distances World Records, let alone somebody from Genesee County, Michigan.
