Supernovae blasts struck the Earth 3 million and 7 million years ago

Supernovae blasts struck the Earth 3 million and 7 million years ago

Universe Today reports: A recent study examines how the Earth was hit by blasts from supernovae (plural form of supernova (SN)) that occurred 3 million years ago (Mya) and 7 Mya with the goal of ascertaining the distances of where these blasts originated. Using the live (not decaying) radioactive isotope 60-Fe, which is produced from supernovae, a team of researchers at the University of Illinois was able to determine the approximate astronomical distances to the blasts, which they refer to…

The rightwing intellectuals who are laying the groundwork for ‘post-Constitutional’ autocratic rule

The rightwing intellectuals who are laying the groundwork for ‘post-Constitutional’ autocratic rule

Jason Wilson writes: In June, rightwing academic Kevin Slack published a book-length polemic claiming that ideas that had emerged from what he called the radical left were now so dominant that the US republic its founders envisioned was effectively at an end. Slack, a politics professor at the conservative Hillsdale College in Michigan, made conspiratorial and extreme arguments now common on the antidemocratic right, that “transgenderism, anti-white racism, censorship, cronyism … are now the policies of an entire cosmopolitan class…

How a ‘Trump train’ attack on a Biden campaign bus foreshadowed Jan 6 — and echoed bloody history

How a ‘Trump train’ attack on a Biden campaign bus foreshadowed Jan 6 — and echoed bloody history

Diane McWhorter writes: The bane of raw intelligence – and history – is that you can always look back and find the signs, but you can’t necessarily look ahead and see where they’re pointing. Many questions remain about the intelligence failures that enabled an insurrectionist mob to lay siege virtually unimpeded to the US Capitol. But here’s one sign that’s been flashing in my head since 6 January 2021. Four days before the 2020 election, a “Trump Train” of motorists…

How the right’s elevation of Robert F. Kennedy Jr. could now backfire

How the right’s elevation of Robert F. Kennedy Jr. could now backfire

Aaron Blake writes: The American right’s efforts to elevate Robert F. Kennedy Jr. were as transparent as they were cynical. The idea, as advanced by Stephen K. Bannon and the like, was clearly to try to embarrass President Biden in the Democratic primary. So they used Kennedy’s inflated early poll standing as an excuse to treat the primary challenge from a fringe figure as something real and threatening. Fox News picked up the ball and ran with it, publishing many dozens of stories…

Energy consumption ‘to dramatically increase’ because of AI

Energy consumption ‘to dramatically increase’ because of AI

Yahoo Finance reports: Artificial intelligence is expected to have the most impact on practically everything since the advent of the internet. Wall Street sure thinks so. The tech-heavy Nasdaq is up 26% year to date thanks to the frenzy over AI-related stocks. But AI’s big breakout comes at a cost: much more energy. Take for example OpenAI’s chatbot ChatGPT. Research done at the University of Washington shows that hundreds of millions of queries on ChatGPT can cost around 1 gigawatt-hour…

A revelation about trees is messing with climate calculations

A revelation about trees is messing with climate calculations

Wired reports: Every year between September and December, Lubna Dada makes clouds. Dada, an atmospheric scientist, convenes with dozens of her colleagues to run experiments in a 7,000-gallon stainless steel chamber at CERN in Switzerland. “It’s like science camp,” says Dada, who studies how natural emissions react with ozone to create aerosols that affect the climate. Clouds are the largest source of uncertainty in climate predictions. Depending on location, cloud cover can reflect sunlight away from land and ocean that would otherwise absorb its…

Progress in the long fight against mosquito-borne disease

Progress in the long fight against mosquito-borne disease

The New York Times reports: Five decades ago, entomologists confronting the many kinds of suffering that mosquitoes inflict on humans began to consider a new idea: What if, instead of killing the mosquitoes (a losing proposition in most places), you could disarm them? Even if you couldn’t keep them from biting people, what if you could block them from passing on disease? What if, in fact, you could use one infectious microbe to stop another? These scientists began to consider…

Evelyn Fox Keller argued that science imposed a narrow masculine framework that distorted inquiry

Evelyn Fox Keller argued that science imposed a narrow masculine framework that distorted inquiry

The New York Times reports: Evelyn Fox Keller, a theoretical physicist, a mathematical biologist and, beginning in the late 1970s, a feminist theorist who explored the way gender pervades and distorts scientific inquiry, died on Sept. 22 at an assisted living home in Cambridge, Mass. She was 87. Her children, Jeffrey and Sarah Keller, confirmed the death. They did not specify a cause. Dr. Keller trained as a physicist and focused much of her early work on applying mathematical concepts…

‘No turning back’: How the Ukraine war has profoundly changed the EU

‘No turning back’: How the Ukraine war has profoundly changed the EU

Patrick Wintour writes: “The EU has changed. There is no turning back. We have turned out the lights behind us and there is basically only one way.” The words of the Danish politician and EU commissioner Margrethe Vestager at a conference in May neatly reflect the mood among the Brussels elite, taken aback at their own ability to shed EU bureaucratic torpor, defend Ukraine, embrace enlargement and move closer to fulfilling Ursula von der Leyen’s ambition for the EU to…

Fulton County court: The first domino falls in RICO case. How many more defendants might flip?

Fulton County court: The first domino falls in RICO case. How many more defendants might flip?

The Daily Beast reports: [A] plea agreement puts [Scott] Hall [the former Fulton County Republican poll watcher and bail bondsman] on probation for five years in exchange for a guilty plea on the five misdemeanors. He will also pay a $5,000 fine, issue a letter of apology to Georgia voters, serve 200 hours of community service, and agree to avoid activities related to polling or administering elections. Perhaps most crucially for his 19 co-defendants, he also agreed to testify truthfully…

Trump’s attack on Milley fuels special counsel’s push for a gag order

Trump’s attack on Milley fuels special counsel’s push for a gag order

Politico reports: Special counsel Jack Smith’s office argued Friday that Donald Trump’s recent attacks on Gen. Mark Milley and one of their own newly appointed prosecutors bolster their case to put a gag order on the former president ahead of his trial in Washington, D.C. In a 22-page filing, senior assistant special counsel Molly Gaston said prosecutors rejected Trump’s claims that their proposed gag order was an attempt to silence him on the campaign trail. Rather, she said, it was…

Trump calls for summary execution of store robbers

The Guardian reports: Donald Trump called for shooting store robbers on Friday in a bleak speech to California Republicans –and warned “this country will die!” if Joe Biden remained president. During the address to GOP members, Trump also railed that wealthy Beverly Hills residents smell because of water denials, and repeated election fraud lies, according to the Associated Press. “We will immediately stop all of the pillaging and theft. Very simply: If you rob a store, you can fully expect…

How to stop AI deepfakes from sinking society — and science

Nicola Jones writes: This June, in the political battle leading up to the 2024 US presidential primaries, a series of images were released showing Donald Trump embracing one of his former medical advisers, Anthony Fauci. In a few of the shots, Trump is captured awkwardly kissing the face of Fauci, a health official reviled by some US conservatives for promoting masking and vaccines during the COVID-19 pandemic. “It was obvious” that they were fakes, says Hany Farid, a computer scientist…

How NASA brought an asteroid to Earth

How NASA brought an asteroid to Earth

David W. Brown writes: On a brisk day in February, 2004, Dante Lauretta, an assistant professor of planetary science at the University of Arizona, got a call from Michael Drake, the head of the school’s Lunar and Planetary Laboratory. “I have Lockheed Martin in my office,” Drake said. “They want to fly a spacecraft to an asteroid and bring back a sample. Are you in?” The two men met that evening with Steve Price, then a director of business development…
