Ancient DNA Reveals Europeโ€™s Last Hunter-Gatherers Survived Thousands of Years Longer Than Expected Ancient DNA shows that hunter-gatherers in northwestern Europe endured for millennia, with women driving a gradual cultural shift toward farming.

The findings that come from an DNA studies fascinate me. The fact that DNA can even be extracted from ancient bones (and sometimes teeth) is amazing.

WATCH: Trump, EPA's Zeldin announce end of scientific basis for U.S. action on climate change The Trump administration on Thursday revoked a scientific finding that long has been the central basis for U.S. action to regulate greenhouse gas emissions and fight climate change, the most aggressiv...

Today, the Trump administration repealed the endangerment finding: the ruling that served as the basis for limits on tailpipe emissions and power plant rules. Without it, weโ€™ll be less safe, less healthy and less able to fight climate changeโ€”all so the fossil fuel industry can make even more money.

Walz: "To Americans who are watching this, I've got a question for you: What side do you want to be on? The side of an all powerful federal govt that can kill, injury, menace, & kidnap its citizens off the streets? Or on the side of a nurse at the VA hospital who died bearing witness to such govt?"

The killing of Alex Pretti is a heartbreaking tragedy. It should also be a wake-up call to every American, regardless of party, that many of our core values as a nation are increasingly under assault.

Minnesota National Guard members have arrived at a federal building and were directed to distribute donuts, coffee, and hot chocolate to anti-ICE protesters. Guard members were issued reflective vests so they would not be mistaken for federal agents.

Alex Pretti was an American hero. He saved lives. He protected people. He cared deeply about his community, unlike the murderous thugs who killed him.

The very last thing he did was try to help a woman who had been pepper-sprayed and violently shoved to the ground by ICE. 1/

Two days ago it was Elissa Slotkin. Last week it was Jerome Powell. Before that, Mark Kelly. Weaponizing the justice system against your opponents is an authoritarian tactic.

The only person not being investigated for the shooting of Renee Good is the federal agent who shot her.

CBS pulled the 60 Minutes CECOT segment, but Canada aired it anyway.

The segment was streaming via Global TV and YouTube (since taken down). Having a VPN set to Canada helped. ๐Ÿ‡จ๐Ÿ‡ฆ

My take, there is no reason we shouldnโ€™t see this. Most of it was known information, easily searchable.

South Australia hit โ€“11ยข/kWh todayโ€”and itโ€™s not even summer. 135% renewables in the grid, utilities paying us to use energy. This is the future Tony Seba mapped out: solar, wind & batteries pushing prices below zero. Fossil baseload is fading fast; superabundance nears. #EnergyTransition #Renewables

Post from President Trump on Truth Social:

Six people were killed, and 24 people were shot, in Chicago last weekend, and JB Pritzker, the weak and pathetic Governor of Illinois, just said that he doesnโ€™t need help in preventing crime. He is CRAZY!!! He better straighten it out, FAST, or weโ€™re coming! MAGA. President DJT

Why donโ€™t you send everyone proof of life first?

(Either way, Chicago doesnโ€™t want you here)

An apartment complex. A headline reads: "Did Switzerland Solve The Housing Crisis?"

The way that housing co-ops work in Switzerland may seem foreign to many. But the central idea is simple: What if homeownership had no profit motive and no capital gains? Advocates say their model could reshape how the world thinks about affordable housing. www.nytimes.com/2025/08/26/r...

View of the central Copenhagen pedestrian street where it widens into a gorgeous square with fountain

One of the most successful pedestrian streets in the world, the Strรธget in Copenhagen, was filled with cars until a 2 year pedestrianization pilot project in 1962. The opposition argued โ€œno cars means no business,โ€ but the street has been a massive retail success, the cityโ€™s busiest shopping street.

Urbanist Brent Toderian Says Tall Buildings Are Not the Problem โ€œSarasota has a huge disconnect between the types of developments being built and the actual needs of the community."

โ€œYou have to hold developers to high standards. You donโ€™t just let anything get built. The answer isnโ€™t to say โ€˜noโ€™ to everythingโ€”itโ€™s to say, โ€˜Yes, if.โ€™ If it meets our vision. If it improves our public realm. If it creates benefits, not just burdens.โ€
