When parental care hurts: Extended parental care and the evolution of overparenting Abstract. In recent years, childrearing in high-income countries has become described as ‘relentless’ in its demands on parents. In response to growing del

New paper out today with Zhian Chen.

We argue that modern intensive parenting is not only exhausting for parents, but in some cases disrupts healthy child development.

What is 'overparenting'? And can evolutionary theory help us understand how we got here?

Rethinking polygamy – new research upends conventional thinking about the advantages of monogamous marriage Simplistic stories about the dangers of polygamy can be compelling and intuitive. But new research suggests some arguments about its harms don’t hold up.

Simplistic stories about the dangers of polygamy can be compelling & intuitive, but what is the evidence that monogamous marriage is advantageous for society?

If one man marries two women, another man must go unmarried, right? No. Demography matters. If sex ratios are skewed towards women, then polygyny can exist alongside universal marriage for men (who want to marry women). If only more people understood demography 😊

From a colleague:

NSF proposal received FOUR "excellent" ratings (the highest possible...that almost never happens).

Rated "highly competitive" in panel summary.

👎 ...but still rejected.

Likely reason: It studied a topic disfavored by this admin.

Fun fact: even as UCLA is being extorted for $1B by a fascist government, its administration is requiring all faculty to install a “security” program that surveils everything we do and shares that information with the federal government.

I’m frustrated to lose our grant & field season, but more concerned about the state of science in the US and the longterm ramifications of this obscene attack on higher ed. I hope that UCLA and other universities actually stand up and fight back, instead of give in to ridiculous demands.

Very disappointed that we were forced to cancel our field season and return early, following the suspension of our NSF grant as part of Trump’s attacks on UCLA. Particularly sad for our students, who spent significant time and effort to join us this year.

A U.S. tile map that depicts the measles vaccination rate for kindergarteners (according to CDC data) in each state from 2013 to 2023. A key explains that for each state, a gray dotted line represents the benchmark for herd immunity: a 95% vaccination rate. Vaccination rates above 95% are shown in blue, while vaccination rates below 95% are shown in orange. Looking at the full map, the trend lines lean much more orange than blue. Measles vaccination rates in most states were below herd immunity in school year 2023-2024.

Federal kindergarten vaccination data shows national rates for four major vaccines, which had held steady before the COVID-19 pandemic, have fallen significantly since.

In fact, measles vaccination rates were below herd immunity in most states in 2023.

Federal investment in UC research Federal funds are the university’s single most important source of support for research, accounting for more than half of UC’s total research awards. Many of California’s leading industries grew from UC research, including biotechnology, computing, semiconductors, telecommunications and agriculture. Providing health care at UC University of California Health (UC Health) is one of the nation’s largest public academic health systems, serving as a critical part of the California safety net. UC trains approximately 36% of the medical residents in California

Measles Heatmap of the number of cases of measles from the 1920s to the 2010s in the United States, shown by stage. Blue is low, red is high. The chart is annotated with a black line that shows the date of the introduction of the vaccine (approx 1963) and the number of cases drops dramatically right after.

Heatmap of vaccines reduced measles cases across US states From 1929 to 2022 There are lots of cases before 193, then it drops and almost disappears completely in the 1990s. 1963: The first measles vaccine is developed by John Enders 1971: The measles-mumps-rubella (MMR) vaccine is developed by Maurice Hilleman 1980: It becomes mandatory for children entering kindergarten to be vaccinated against measles Data source: Project Tycho (2018); Centers for Disease Control and Prevention (1959-2022) OurWorldinData.org - Research and data to make progress against the world's largest problems.

This statement from the NSF is insane.

Science is, in essence, designed to separate the true from the false.

Understanding how falsehoods spread is key to the scientific endeavor. It is not a violation of free speech to be proven wrong.

Haunted by hopelessness: 12 Zambians share their stories as HIV drugs run out Mothers and children, husbands and wives, doctors, truck drivers and religious leaders are all grappling with the fallout from the sudden U.S. cuts in aid.

I look at close to 100 stories a week and even more outside of work. I’ve done this ten years.

This is among the most horrific things I’ve ever read — testimony from dying children whose access to medicine has been cut off by the Trump administration.

oh hell yes

The NYT has profiled Rufo repeatedly but never come close to asking the vital questions that Larry lays out so well here:

Science’s big problem is a loss of influence, not a loss of trust Evidence shows that science and scientists remain highly trusted. But genuine scientific voices are not shouting loud enough over the noise to hold sway.

The real problem about science isn't about loss of trust. It's about not having a voice, a counter. @nature.com
