Unfalsifiable by Design: A Year of Trying and Failing to Reproduce a Human Microbiome and Autism Study The myth of open data, reproducibility, responsibility, and accountability in science, and your role in it

How every layer of science's "self-correcting machinery" failed when Iva Veseli and I simply wanted to reproduce the findings of a high-profile study on gut microbiome and autism:

Earth.

Artemis II Commander Reid Wiseman took this picture of Earth from the Orion spacecraft after completing the translunar injection burn. There are two auroras (top right & bottom left) and zodiacal light (bottom right) is visible as the Earth eclipses the Sun. 🧪🔭 #Artemis

A massive No Kings crowd turns out in Minneapolis, Minnesota

3 weeks ago 2302 473 42 59

thoughts on today:

1) the protests are good, actually

2) you should go to one of you can

3) it will do you good to see how many other people also hate this guy

4) you might meet people who you can organize with

5) there are more of us than there are of them

6) we are going to win

Figure showing comparative changes in cottonwood biomass allocation among stem, limbs, leaves and roots over time between the control—no irrigation and low fertilizer inputs, and the high irrigation and high fertilization treatment.

... measurements, including the full excavation of tree root balls for comprehensive estimation of belowground biomass and soil carbon 😍
It was fun to collaborate and help get this study revived and finalized!

I just resigned from NASA. It breaks my heart to leave, but I’ve become convinced the best path forward is to do the best science I can, and that can’t be here anymore. I’m still in love with the promise of those four magic letters. Ad astra per aspera, and remember: Earth is the only good planet.

The heat energy we added to the ocean LAST YEAR is the equivalent of:
- Detonating ten hydrogen bombs every minute
- operating over a hundred large power plants continuously for all of written human history
- Five times all the electricity human beings have ever used

It’s the “season of love and giving”…but this year, doesn’t it seem more like a “season of fear and taking”? Like many of you, I’ve been saddened by the human impact of draconian government budget cuts and how angry many housed Americans are at unhoused Americans.

I don’t know who needs to hear this but the CDC is being eviscerated right now. America is not going to have any kind of outbreak response capacity after tonight. Americans’ health data is no longer secure. Say goodbye to federal public health in any capacity. It’s a disaster. We won’t recover.

A Stylized Study of the Climate Response to Longwave and Shortwave Forcing at the Altitude of Aviation‐Induced Cirrus For the same magnitude of LW and SW forcing at the altitude of aviation-induced cirrus, climate sensitivity is larger when the forcing is imposed at high latitudes For the same change in concentr...

We could get rid of half of the radiative forcing of climate caused by aviation if we could get airlines to stop making contrails, mostly by flying a few thousand feet higher or lower.

New open-access paper from a climate physics perspective.

Quantifying potential abiotic drivers of the ‘nurse plant effect’ in two dominant shrub species of the northern Chihuahuan Desert

Yessss new paper is OUT! Scott Ferrenberg led this effort to tease apart "nurse plant" effects in the Chihuahuan Desert.

Spoiler alert: don't underestimate the power of a little shade in arid systems

High-level conclusion: the environmental footprint of poplar-derived cellulosic ethanol production is much more sensitive to poplar yield than it is to poplar biomass quality (sugar content).

Similar what we concluded previously for switchgrass— doi.org/10.1021/acss...
