Ok folks, now more than ever, we need to Be Kind and do Good Science. This means digging in, producing the evidence, communicating clearly and sincerely, celebrating our collective curiosity, and being mindful of the spaces we are and can be in.

Hellyeah

Hello everyone! For those who might not know, I've made the move to the EU as Assoc. Professor of Global Health at the #Luxembourg Centre for Socio-Environmental Systems. Connecting global health, biodiversity, and sustainable practices to work towards a more sane(ish) world. www.uni.lu/lcses-en/

Fingerprint is here! Great long thread about our new Nature paper that dropped today (but has been multiple years of enormous team effort).

The “jaw-dropping” El Niño currently heating up the planet has burst through the highest temperature ever recorded for the phenomenon, several months before its expected peak.

Yet another measles death here in PA. That's two in 4 or 5 days, and this one was an 18 year-old. And of course, unvaccinated. There is no limit to my contempt toward those who continue to undermine vaccine confidence in the face of these avoidable tragedies. www.inquirer.com/health/fourt...

Sixty years ago today, the starship Enterprise launched and with it, a vision of the future where humanity had moved beyond its divisions. I was there at the beginning, and I can tell you...

Hikers using ChatGPT to navigate Mount Shasta have gotten lost. In one instance this week, a group of climbers had to be rescued: “It was terrible — terrible — not even close to accurate.”

SDM/ENM folks - if all your presence points are from one landscape/land cover type, but psedo-absences are generated from multiple types, what impact will this have on the model?

This is not an isolated event. It and other "unusual" changes in the Earth's topography and oceans are a result of climate change taking place, caused by denial of science. #BlueEarth #DV1 #ProudBlue #Pinks nautil.us/an-ice-islan...

These records indicate that global sea surface temperatures are now higher than at any time in at least 12,000 years and are probably reaching levels experienced during the last interglacial period, around 123,000 to 128,000 years ago. www.washingtonpost.com/weather/2026...

"It Just Got Way Easier to Sue Fossil Fuel Companies Over Climate Change" by Rachel Santarsiero for @motherjones.com: www.motherjones.com/environment/...

The world’s oceans hit 21.10 degrees Celsius last Saturday, breaking a record set in 2024. And it's only going to get worse.

Over the weekend, a storm in the Baltic states caused significant disruption to power supplies and at least 2 deaths. An experimental reanalysis-based attribution approach suggests that ~20% more rain fell than if the same weather pattern had occurred in a world that was 1°C cooler.

New NSF BIO solicitation says expected number of awards is 250-300. Historically, the number of awards is closer to 800-1000 for the Directorate of Bio Sciences: grantwitness.org/nsf/analyses... Unless I'm missing large, non-core programs, this seems really not good?

Happy World Mosquito Day 2026. Rainbow maps are back, now in an accesssible palette. If you'd like CMIP6 dengue thermal suitability grids for Ae aegypti and Ae albopictus, for all the runs in our recent preprint, and more (everything we could get hold of), head to the dataverse: shorturl.at/OTntY

This is REALLY important. “Over 50% of Americans say climate change is a serious threat; only 10% think their compatriots feel the same That perception gap on the issue is among the highest in the world, per a new Gallup poll.” They want you to think you’re alone. You’re not. #ClimateCrisis

EVERY STORY ABOUT BEAVERS FOR THE LAST DECADE READS LIKE: WE RELEASED A DOZEN PADDLE TAILED LITTLE FREAKS AND THEY IMMEDIATELY BEGAN A TERRAFORMING PROJECT THAT REVERSED A CENTURY OF ECOLOGICAL DAMAGE IN THREE WEEKS.

New CDC warning about severe infection with arboviruses such as West Nile virus in patients on anti-CD20 antibodies. Also notes a new syndrome of fatal, slowly progressive encephalitis with orthobunyaviruses such as Jamestown Canyon virus in patients on anti-CD20 antibodies #IDSky

“One mile on a bike is a $.42 economic gain to society, one mile driving is a $.20 loss.” “Which means that Copenhagen, a city of 1.2 million people, saves $357 million a year on health costs because something like 80% of its population commutes by bike.” #CityMakingMath Some costs are savings.

"ugh I'm that weirdo" I mutter, stumbling through the shrubs at @epi.ufl.edu to get close to this beauty. Look at that web! I am in awe.

Severe Covid leads to persistent viral reactivation, with >10 different viruses noted in the first 40 days after hospital admission. Long Covid was specifically associated with reactivation of latent Anelloviridae virus @nature.com www.nature.com/articles/s41...

How about solar panels? Can we just have those?

This is a remarkably extreme statistic. Bordeaux, France has recorded more days >40°C in 2026 than in the entire 105 year period combined dating back to 1920 when records began. This summer has been so far above extreme it’s difficult to put into words. Chart: @WxNB_

‘Immediately stop all outdoor activities’: South Korea records its highest ever temperature - 42.5C #climatecrisis www.theguardian.com/world/2026/a...

Pandemic risk—where is it heading, and how can we (re-)conceptualize it within current modeling frameworks? Check out our new preprint below! @carlsonlab.bsky.social @viralemergence.org

The US owes the Pan-American Health Organization $135 million in past dues. Trump's budget proposal cuts funding for PAHO entirely, even though our contribution is 0.001% of federal spending. The result will be even weaker defenses agst measles, dengue & more. www.nytimes.com/2026/07/30/h...

OH WOW! If you like seeing amazing pictures (of tropical bugs and others, mostly bugs), check out this thread, and keep clicking the 'replies' to see the sheer magnitude. So gorgeous. Such a lovely post. Thank you @ibycter.bsky.social for this treat.

why the fuck is this guy allowed to just smash shit into the moon

Moving quickly... still hilarious

Keep on shouting this until they listen

Moon rising over the end of a very hot day here. Happy Friday folks, have some weekend.

Whew, the editors of @science.org are getting real.

This is a very real aspect of the (dumb) structure of US health coverage. It creates terrible work environments, stifles creative moves, and "job lock" is a great term, but doesn't really capture the horror.

"My message to the people of the UK is that I'll train the new guy but you're going to have to stick with one of them eventually."

👏🏽👏🏽 India approves it’s first vaccine for dengue www.reuters.com/business/hea...

I'd be great at it. I have no siblings. Actually, I'd suck at it, let's be honest, I would get bored after two weeks of no job, and would probably go back to doing what I do.

"Pandemic prediction in the space age: use of EOS data" - In a time of lots of Earth Observation System (EOS) data, the call to use it for predicting pandemics is out there. So how does it look? with @lippikiyay.bsky.social and Jakob Meredith bit.ly/4eUstUK - sjryan3.shinyapps.io/pand_eos_dash/

"NSF employees are now concerned that the $1 billion of withheld funds will not be released. If they are not, the combination of withheld funds and clawbacks would result in funding cuts of more than 30% for most directorates compared with their planned spending for 2025"

Get you colleagues who know it's your birthday later in the month when you won't be in the same place!!

"By unpacking who can actually detect and report these infections, the authors reveal that what we count as "disease risk" often says as much about societies as it does about microbes." Thanks for the write up of this work led by @samsambado.bsky.social www.clearskyscience.com/en/10.1038/s...
