The universe was born in light. If modern cosmology is right, for the first forty thousand years or so after the Big Bang the most important component in the young, hot universe was electromagnetic radiation, a situation that continued until the universe had cooled sufficiently for the first hydrogen and helium atoms to form. Temperatures were still high enough at that point for the cosmos to be filled with an opaque, glowing plasma. After a few hundred thousand years, as the universe...

Guest post by Jeff Mosenkis of Innovations for Poverty Action. A quick note, my posting frequency has slowed down in 2021, thanks for sticking with it. One reason has been that I’ve been co-authoring another set of links with my brilliant IPA colleagues, Luciana Debenedetti & Rachel Strohm, every other week focused on new research on COVID and social protection (this week’s is here). Among other, I think I also hit what I now realize was a quarantine burnout. If it’s helpful to anybody...

In the last few days, there have been quite a few reports of studies suggesting that the number of people who have been exposed to Covid-19 is far larger than previously thought. These studies have been based on testing for antibodies against coronavirus (it is unclear whether they are specific to Covid-19, or might reflect exposure to other coronaviruses). I’m finding it difficult to square these estimates with inferences from direct testing, which (as I understand it) tests...

Guest post by by Jeff Mosenkis of Innovations for Poverty Action Chris has been threatening it for a while but looks like he’s finally done it (click through to see the full thread and description of why his answer’s not what you might expect): Set your 2-year clock for my book: Why We Fight. Everything you need to know about why gangs, nations, and other groups go to war, and how to stop it. Just signed with editor Wendy Wolf @VikingBooks, an imprint @PenguinUSA! Huge credit to agent...

Guest post by Jeff Mosenkis of Innovations for Poverty Action J-PAL North America has released a pretty spiffy-looking toolkit for doing evaluations in North America, covering conceptual things like assessing feasibility as well as technical things like power calculations, with links to code and more resources (most of the info isn’t specific to North America).It’s been a big few weeks for open science:It is the policy of the American Economic Association to publish papers only if the data...

WHO measles surveillance dataGuest post by Jeff Mosenkis of Innovations for Poverty Action Thanks for being patient while the links were sleeping, expect some summer disruptions of schedule as wellMeasles cases are up 300% over last year with outbreaks in the U.S., Europe, The Philippines, Myanmar, and several African countries. I heard a PSA that adults vaccinated before a certain period (when the vaccine process changed) might no longer be immune. So I got checked and sure enough I wasn’t,...

This is a big deal even though it won't be noticed by most people. However, precise measurement essential to science and measurement involves application of metrics defined by criteria. The units and their criteria are arbitrary. There was no such thing as a kilogram prior to the development and introduction of the metric system. Same with other measurement systems. The "trick" is to establish a constant criterion in a relative universe. That is as close to an absolute as human can...

Pick up your own 5-HTTLPR gene research summary shirt on etsy.Guest post by Jeff Mosenkis of Innovations for Poverty Action IPA’s looking for a Director of Poverty Measurement. In particular the job involves overseeing the Poverty Probability Index, a short, country-specific tool practitioners use to estimate poverty rates, and developing new non-monetary measures (requires strong quant background). Please share with anybody who might be interested.How the government of Odisha, one of...

The Voyager 2 spacecraft has just passed through the heliopause and into interstellar space, forty years after it was launched. On the one hand that’s a stunning technological achievement and a reminder of the wonderful universe we live in. On the other, it’s a reminder that humans will never go out to explore this universe, or even leave Earth in significant numbers. Although Voyager 2 has passed the heliopause it is still within the gravitational field of the sun. It would take...

Last week, I spoke at a forum on Adani and indigenous rights organized by the UQ Human Rights Consortium. It was an excellent line-up, with Murrawah Johnson – Youth Spokesperson Wangan and Jagalingou Traditional Owners Council, Activist of the Year (Ngara Institute) and on the 50 Grist list – acknowledging her place amongst the world’s best and brightest fighting for the planet. Dr Michelle Maloney – Co-founder and National Convenor, Australian Earth Laws Alliance David Ritter – Chief...
