    This week we talk about H5N1, fowl plague, and viral reservoirs.We also discuss the CDC, raw milk, and politics.Recommended Book: Nexus by Yuval Noah HarariTranscriptIn late-January of 2025, staff at the US Centers for Disease Control, the CDC, were told to stop working with the World Health Organization, and data, and some entire pages containing such data, and analysis of it, were removed from the CDC’s web presence—the collection of sites it maintains to provide information, resources, and raw research numbers and findings from all sorts of studies related to its remit.And that remit is to help the US public stay healthy. It provides services and guidelines and funding for research and programs that are meant to, among other things, prevent injury, help folks with disabilities, and as much as possible, at least, temper the impacts of disease spread.Its success in this regard has been mixed, historically, in part because these are big, complex, multifaceted issues, and with current technology and existing systems it’s arguably impossible to completely control the spread of disease and prevent all injury. But the CDC has also generally been a moderating force in this space, not always getting things right, itself, but providing the resources, monetary and otherwise, to entities that go on to do big, generally positive things across this range of interconnected fields.Many of the pages that were taken down from the CDC’s web presence in late-January popped back up within a few weeks, and now, according to experts from around the world, these pages have been altered—some mostly the same as they were, but others missing a whole lot of data, while still others now contain misinformation and/or polemic. A lot of that misinformation and political talking points are related to things the recently re-ascendent Trump administration has made a cornerstone of its ideological platform, including anti-trans policies and things that cast skepticism on vaccines, abortion, birth control, and even information related to sexually transmitted infections.Scientists doing research that is in any way connected to concepts like diversity, equality, and inclusivity—so-called DEI issues—have been forced to halt these studies, and research that even includes now-banned words in different contexts—words like gender, LGBT, and nonbinary—have likewise been halted, or in some cases banned altogether. Data sets and existing research that happen to include any reference to this collection of terms have likewise been pulled from the government’s publicly accessible archives; so some stuff actually connected to DEI issues, but initial looks into what’s been halted and cancelled shows that things like cancer research and other, completely non-political stuff, too, has been stopped because somewhere in the researchers’ paperwork was a word that is now not allowed by the new administration.All of which is part of a much bigger story, one that I won’t get into right now, as it’s still evolving, and is very much it’s own thing; that of the purge of government agencies that’s happening in the US right now, at the apparent behest of the president, and under the management of the world’s wealthiest person, Elon Musk, via his task force, the Department of Government Efficiency, or DOGE.This process and the policies underpinning it are facing a lot of legal pushback, even from other Republicans, in at least a few cases. But it’s also a story that’s evolving by the day, if not the minute, and the long-term ramifications are still up in the air; some are calling it the first move in an autogolpe, a coup from within, while others are calling it a hamfisted attempt to seem to be doing things, to be reducing expenses in the government, but in such a way that none of the actions will be particularly effective, and most will be countered by judicial decisions, once they catch up with the blitzkrieg-like speed of these potentially illegal actions.There’s been some speculation that this will end up being more of an albatross around the neck of the administration, than whatever it is they actually hope to accomplish with it—though of course there are just as many potentially valid concerns that, again, this is a grab for power, meant to centralize authority within the executive, with the president, and that, in turn could make it difficult for anyone but a Republican, and anyone but a staunch ally of Trump and his people, to ever win the White House again, at least for the foreseeable future.But right now, as all those balls are in the air and we’re waiting to see what the outcome of that flurry of activity will actually be, practically, I’d like to focus on one particular aspect of this culling of the CDC’s records, publicly available information, and staff.What I’d like to talk about today is bird flu, and what we think we know about its presence in the US right now, and how that presence is being felt ...

    This week we talk about DART, extinction events, and asteroid 2024 YR4.We also discuss Bruce Willis, Theia, and the Moon.Recommended Book: Exadelic by Jon EvansTranscriptIn the 1998 action flick Armageddon, an asteroid the size of Texas is nudged into a collision course with earth by a comet, and NASA only notices it 18 days before impact.The agency recruits a veteran oil driller, played by Bruce Willis, to fly out to the asteroid and drill a hole in it, and to detonate a nuke in that hole, which should destroy it before it hits earth, which undetonated, that rock not broken up ahead of time, would wipe out everything on the planet. It’s a fun late-90s flick loaded with some of the biggest names of the era, so I won’t ruin it for you if you haven’t seen it, but the crux of the plot is that there’s a lot going on in space, and at some point there’s a chance one of these big rocks hurling around in the void will line up just right with earth’s orbit, and that rock—because of how fast things move in space—would hit with enough force to wipe out a whole lot of living things; perhaps all living things.This film’s concept was predicated on historical events. Not the oilmen placing a nuke on a rogue asteroid, but the idea of an asteroid hitting earth and killing off pretty much everything.One theory as to how we got our Moon is that an object the size of Mars, called Theia, collided with Earth around 4.5 billion years ago. That collision, according to some versions of the so-called “giant impact hypothesis,” anyway, could have brought earth much of its water, as the constituent materials required for both water and carbon based life were seemingly most prevalent in the outer solar system back in those days, so this object would have slammed into early earth, created a disk of debris that combined that early earth’s materials with outer solar system materials, and that disk would have then reformed into a larger body, earth, and a smaller body, the moon.In far more recent history, though still unthinkably ancient by the measure of a human lifespan, an asteroid thought to be somewhere between 6 and 9 miles, which is about 10 to 15 km in diameter hit off the coast of what is today Mexico, along the Yucatan Peninsula, killing about 70% of all species on earth.This is called the Chicxulub Event, and it’s believed to be what killed the dinosaurs and all their peer species during that period, making way for, among other things, early mammals, and thus, eventually, humans.So that was an asteroid that, on the low end, was about as wide as Los Angeles. You can see why those in charge back in the 90s tapped Bruce Willis to help them handle an asteroid the size of Texas.Thankfully, most asteroid impacts aren’t as substantial, though they can still cause a lot of damage.What’s important to remember is that because these things are moving so fast, even though part of their material will be burnt up in the atmosphere, and even though they might not all be Texas-sized, they generate an absolutely boggling amount of energy upon impact.The exact amount of energy will vary based on all sorts of things, including the composition of the asteroid , the angle at which it hits, and where it hits; an oceanic impact will result in a whole lot of that energy just vaporizing water, for instance, while a land impact, which is less common because a little more than 70% of the planet is water, will result in more seismic consequences.That said, an asteroid that’s about 100 meters in diameter, so about 328 feet, which is a lot smaller than the aforementioned 6 to 9 mile asteroid—a 100 meter, 328 foot object hitting earth can result in a force equivalent to tens of megatons of TNT, each megaton equaling a million tons, and for comparison, the atomic bombs dropped on Hiroshima and Nagasaki at the end of WWII ranged from 15,000 to 21,000 tons of TNT, mere kilotons. So a 100 meter, 328 foot asteroid hitting earth could generate somewhere between a few hundred thousand and a few million atomic bombs’ worth of energy.None of which would be particularly devastating on a planetary scale, in the sense that the ground beneath out feet would barely register such an impact. But the thin layer of habitable surface where most or all of the world’s life exists, certainly does. And that’s the other issue here, is that on top of even a relatively small asteroid being a city-killer, wiping out everyone and everything in a large area around where it strikes, it can also cause longer-term devastation by hurling a bunch of water and soil and detritus and dust and ash into the atmosphere, acting as a cloak around the planet, messing with agriculture, messing with growth patterns and other cycles for plants and animals; the water and heat cycles completely thrown off. All of which can cause other knock-on effects, like more severe storms in unusual places, periods of famine, and even conflict over scarcer resources.What I...

    This week we talk about tax hikes, free trade, and the madman theory of negotiation.We also discuss EVs, Canada, and economic competition.Recommended Book: How Sanctions Work by Narges Bajoghli, Vali Nasr, Djavad Salehi-Isfahani, and Ali VaezTranscriptOn January 20, 2025, the 45th President of the United States, Donald Trump, was inaugurated as the 47th President of the US following a hard-fought election that he ultimately won by only a little bit in terms of the popular vote—49.8% to 48.3%—but he won the electoral vote by a substantial margin: 312 to opponent Kamala Harris’ 226.Trump is the oldest person in US history to assume the country’s presidency, at 78 years old, and he’s only the second US president to win a non-consecutive term, the first being Grover Cleveland back in 1893.This new Trump presidency kicked off even before he officially stepped into office, his people interviewing government officials and low-level staff with what have been called loyalty tests, to assess who’s with them and who’s against them, including questions about whether they think the previous election, which Trump lost to former president Biden, was rigged against Trump—a conspiracy theory that’s popular with Trump and many of his supporters, but for which there’s no evidence.There was also a flurry of activity in Israel and the Gaza Strip, last minute negotiations between then-president Biden’s representatives gaining additional oomph when Trump’s incoming representatives added their heft to the effort, resulting in a long-pursued ceasefire agreement that, as of the day I’m recording this at least, still holds, a few weeks after it went into effect; hostages are still being exchanged, fighting has almost entirely halted between Israeli forces and Hamas fighters in Gaza, and while everyone involved is still holding their breath, worried that the whole thing could fall apart as previous efforts toward a lasting ceasefire have, negotiations about the second phase of the three-phase ceasefire plan started yesterday, and everything seems to be going mostly according to plan, thus far.That said, other aspects of the second Trump presidency have been less smooth and less celebrated—outside of the president’s orbit, at least.There have been a flurry of firings and forced retirements amongst long-serving public officials and employees—many seemingly the result of those aforementioned loyalty tests. This has left gaps in many fundamental agencies, and while those conducting this purge of said agencies have claimed this is part of the plan, and that those who have left or been forced to leave are part of the alleged deep state that has it in for Trump, and who worked against him and his plans during his first presidency, and that these agencies, furthermore, have long been overstaffed, and staffed with people who aren’t good at their jobs—so these purges will ultimately save the government money, and things will be restructured to work better, for some value of “better,” anyway.There have been outcries about this seeming gutting of the system, especially the regulatory system, from pretty much everyone else, national and international, with some analysts and Trump opponents calling this a coup in all but name; doing away with the systems that allow for accountability of those in charge, basically, and the very structures that allow democracy to happen in the country. And even short of that, we’re seeing all sorts of issues related to those empty seats, and could soon see consequences as a result of the loss of generational knowledge in these agencies about how to do things; even fairly basic things.All of which has been accompanied by a wave of revenge firings and demotions, and threats of legal action and even the jailing of Trump opponents. In some cases this has included pulling security details from anyone who’s spoken out against Trump or his policies in the past, including those who face persistent threats of violence, usually from Trump supporters.On the opposite side, those who have stuck by Trump, including those who were charged with crimes related to the January 6 incursion at the US Capitol Building, have been pardoned, given promotions, and at times publicly celebrated by the new administration. Some have been given cushy jobs and promotions for the well-connected amongst his supporters; Ken Howery the partner of venture capitalist and owner of government contractor Palantir, Peter Thield, and close ally of serial CEO and enthusiastic Trump supporter Elon Musk, was recently made ambassador to Denmark, for instance.Some of these moves have caused a fair bit of chaos, including a plane colliding with a military helicopter, which may have been the result of understaffing at the FAA, alongside an executive order that froze the funding of federal programs across the country.That executive order has been blocked by judges in some areas, and the Trump administration has since ...
