Episode Summary
A new study of more than 200,000 Southern California births finds prenatal exposure to wildfire smoke, especially in the third trimester, is associated with a higher likelihood of autism diagnosis in children. Researchers estimated exposure using modeled PM2.5 levels at home addresses and found the strongest link during multi-day smoke stretches: about 10% higher risk after 1 to 5 smoky days, 12% higher after 6 to 10 days, and 23% higher after more than 10 days. Experts emphasize the effect size is modest, the study cannot prove cause and effect, and limitations include unknown indoor exposure and protective steps like air filters or masks.
Also today, Brooklyn Peltz Beckham publicly says he does not want to reconcile with his family, alleging his parents and their team “attacked” him and his wife, Nicola Peltz Beckham, in the press. Sir David Beckham has not directly responded to the claims, but speaking at the World Economic Forum in Davos, he addressed social media generally and said children are “allowed to make mistakes.”
Show Notes
New research tracking more than 200,000 births in Southern California links prenatal exposure to wildfire smoke to a higher likelihood of autism diagnosis, with the strongest association in the third trimester. Using modeled PM2.5 at home addresses, the study reports roughly a 10% higher risk after 1 to 5 smoky days, 12% higher after 6 to 10 days, and 23% higher after more than 10 days. Experts stress the effect size is modest and the findings do not prove causation, especially because indoor exposure and protective steps like air filters are hard to measure. Separately, Brooklyn Peltz Beckham says he does not want to reconcile with his family, alleging press attacks on him and Nicola Peltz Beckham. Sir David Beckham has not directly addressed the claims.

[00:00] Cole Mercer: From Neural Newscast, I'm Cole Mercer.
[00:03] Daniel Brooks: And I'm Daniel Brooks.
[00:05] Cole Mercer: Today, a major health question in California.
[00:08] Cole Mercer: Can wildfire smoke exposure during pregnancy affect autism risk in children?
[00:15] Cole Mercer: Later, the Beckham Family Feud moves into the open after Brooklyn Peltz Beckham posts his first detailed public comments.
[00:23] Cole Mercer: Turning now to California.
[00:25] Cole Mercer: A new study links wildfire smoke in late pregnancy to a higher likelihood of an autism diagnosis.
[00:33] Cole Mercer: The research looks at health records for more than 200,000 births in Southern California,
[00:39] Cole Mercer: from 2006 through 2014.
[00:43] Cole Mercer: It estimates exposure using modeled PM2.5 levels at-home addresses during pregnancy.
[00:50] Cole Mercer: The strongest association shows up in the third trimester, especially during multi-day smoke stretches.
[00:58] Cole Mercer: The study reports about a 10% higher risk after one to five smoky days, 12% higher after six to ten, and 23% higher after more than ten.
[01:10] Daniel Brooks: The practical takeaway is risk management, not panic.
[01:15] Daniel Brooks: The authors and outside experts stress this is an association, not proof of cause.
[01:21] Daniel Brooks: And the effect size is modest.
[01:23] Daniel Brooks: There are also limits.
[01:25] Daniel Brooks: The exposure estimates are for outdoor air, not what people breathe indoors.
[01:30] Daniel Brooks: Researchers cannot see who used HEPA filters, wore masks, or stayed inside during smoke spikes.
[01:37] Cole Mercer: Still, the mechanism is plausible. Wildfire PM 2.5 can lodge deep in the lungs and enter the bloodstream.
[01:46] Cole Mercer: Researchers also note the third trimester is a critical window for brain growth and development.
[01:51] Daniel Brooks: For cities, the near-term issue is preparedness during smoke days,
[01:56] Daniel Brooks: clean air centers, clear alerts, and support for pregnant people and families.
[02:02] Daniel Brooks: Guidance often comes down to staying indoors, improving filtration, and following local public
[02:08] Daniel Brooks: health instructions.
[02:09] Cole Mercer: In other news, Brooklyn Peltz-Bekham says he does not want to reconcile with his family
[02:14] Cole Mercer: in his first direct public response to months of feud rumors.
[02:18] Daniel Brooks: In a series of Instagram posts, he alleges his parents and their team attacked him and
[02:24] Daniel Brooks: his wife, Nicola Peltz-Bekham, through press coverage.
[02:28] Daniel Brooks: He said,
[02:28] Daniel Brooks: He says he stayed quiet for years, but felt forced to respond publicly.
[02:33] Daniel Brooks: Sir David Beckham has not directly addressed the accusations.
[02:38] Cole Mercer: At the Ruled Economic Forum in Davos, he spoke more generally about social media and said
[02:44] Cole Mercer: children are allowed to make mistakes.
[02:46] Cole Mercer: The immediate impact is reputational because the Beckham's operate as a global brand across
[02:53] Cole Mercer: sport, fashion, and media.
[02:55] Cole Mercer: When a private dispute turns public, every statement becomes part of that brand narrative.
[03:01] Daniel Brooks: Next, we will be watching whether the family responds in a coordinated way or lets this play out online.
[03:09] Daniel Brooks: In the short term, the pressure point is attention, and attention tends to reward escalation.
[03:15] Cole Mercer: I'm Cole Mercer.
[03:17] Daniel Brooks: And I'm Daniel Brooks.
