As our climate warms beyond its historical range , scientists increasingly need to study climates deeper in the planet’s past to get information about our future . One object of study is a warming event known as the Miocene Climate Optimum (MCO) from about 17 to 15 million years ago. It coincided with floods of basalt lava that covered a large area of the Northwestern US, creating what are called the “Columbia River Basalts.” This timing suggests that volcanic CO ₂ was the cause of the warming.

Those eruptions were the most recent example of a “Large Igneous Province,” a phenomenon that has repeatedly triggered climate upheavals and mass extinctions throughout Earth’s past. The Miocene version was relatively benign; it saw CO ₂ levels and global temperatures rise, causing ecosystem changes and significant melting of Antarctic ice, but didn’t trigger a mass extinction.

A paper just published in Geology , led by Jennifer Kasbohm of the Carnegie Science’s Earth and Planets Laboratory, upends the idea that the eruptions triggered the warming while still blaming them for the peak climate warmth.

Most people are “very” or “extremely” concerned about the state of the natural world, a new global public opinion survey shows.

Roughly 70 percent of 22,000 people polled online earlier this year agreed that human activities were pushing the Earth past “ tipping points ,” thresholds beyond which nature cannot recover, like loss of the Amazon rainforest or collapse of the Atlantic Ocean’s currents . The same number of respondents said the world needs to reduce carbon emissions within the next decade.

Boeing's Starliner spacecraft sailed to a smooth landing in the New Mexico desert Friday night, an auspicious end to an otherwise disappointing three-month test flight that left the capsule's two-person crew stuck in orbit until next year.

Cushioned by airbags, the Boeing crew capsule descended under three parachutes toward an on-target landing at 10:01 pm local time Friday (12:01 am EDT Saturday) at White Sands Space Harbor, New Mexico. From the outside, the landing appeared just as it would have if the spacecraft brought home NASA astronauts Butch Wilmore and Suni Williams, who became the first people to launch on a Starliner capsule on June 5 .

But Starliner's cockpit was empty as it flew back to Earth Friday night. Last month, NASA managers decided to keep Wilmore and Williams on the International Space Station (ISS) until next year after agency officials determined it was too risky for the astronauts to return to the ground on Boeing's spaceship . Instead of coming home on Starliner, Wilmore and Williams will fly back to Earth on a SpaceX Dragon spacecraft in February. NASA has incorporated the Starliner duo into the space station's long-term crew.

The three princes of Sarandib—an ancient Persian name for Sri Lanka—get exiled by their father the king. They are good boys, but he wants them to experience the wider world and its peoples and be tested by them before they take over the kingdom. They meet a cameleer who has lost his camel and tell him they’ve seen it—though they have not—and prove it by describing three noteworthy characteristics of the animal: it is blind in one eye, it has a tooth missing, and it has a lame leg.

After some hijinks the camel is found, and the princes are correct. How could they have known? They used their keen observational skills to notice unusual things, and their wit to interpret those observations to reveal a truth that was not immediately apparent.

It is a very old tale, sometimes involving an elephant or a horse instead of a camel. But this is the version written by Amir Khusrau in Delhi in 1301 in his poem The Eight Tales of Paradise , and this is the version that one Christopher the Armenian clumsily translated into the Venetian novel The Three Princes of Serendip , published in 1557; a publication that, in a roundabout way, brought the word “serendipity” into the English language.

A person in Missouri with no reported exposure to animals was confirmed to have been infected with H5-type bird flu, the Missouri Department of Health and Senior Services (MDHSS) announced late Friday .

MDHSS reported that the person, who has underlying medical conditions, was hospitalized on August 22 and tested positive for an influenza A virus. Further testing at the state's public health laboratory indicated that the influenza A virus was an H5-type bird flu. The Centers for Disease Control and Prevention has now confirmed that finding and is carrying out further testing to determine if it is the H5N1 strain currently causing a widespread outbreak among US dairy cows.

It remains unclear if the person's bird flu infection was the cause of the hospitalization or if the infection was discovered incidentally. The person has since recovered and was discharged from the hospital. In its announcement, MDHSS said no other information about the patient will be released to protect the person's privacy.

Boeing's Starliner spacecraft will gently back away from the International Space Station Friday evening, then fire its balky thrusters to rapidly depart the vicinity of the orbiting lab and its nine-person crew.

NASA asked Boeing to adjust Starliner's departure sequence to get away from the space station faster and reduce the workload on the thrusters to reduce the risk of overheating, which caused some of the control jets to drop offline as the spacecraft approached the outpost for docking in June.

The action begins at 6:04 pm EDT (22:04 UTC) on Friday, when hooks in the docking mechanism connecting Starliner with the International Space Station (ISS) will open, and springs will nudge the spacecraft away its mooring on the forward end of the massive research complex.

NASA and Blue Origin announced Friday that they have agreed to delay the launch of the ESCAPADE mission to Mars until at least the spring of 2025.

The decision to stand down from a launch attempt in mid-October was driven by a deadline to begin loading hypergolic propellant on the two small ESCAPADE (Escape and Plasma Acceleration and Dynamics Explorers) spacecraft. While it is theoretically possible to offload fuel from these vehicles for a future launch attempt, multiple sources told Ars that such an activity would incur significant risk to the spacecraft.

Forced to make a call on whether to fuel, NASA decided not to. Although the two spacecraft were otherwise ready for launch, it was not clear the New Glenn rocket would be similarly ready to go.

Researchers have discovered more than 280 malicious apps for Android that use optical character recognition to steal cryptocurrency wallet credentials from infected devices.

The apps masquerade as official ones from banks, government services, TV streaming services, and utilities. In fact, they scour infected phones for text messages, contacts, and all stored images and surreptitiously send them to remote servers controlled by the app developers. The apps are available from malicious sites and are distributed in phishing messages sent to targets. There’s no indication that any of the apps were available through Google Play.

A high level of sophistication

The most notable thing about the newly discovered malware campaign is that the threat actors behind it are employing optical character recognition software in an attempt to extract cryptocurrency wallet credentials that are shown in images stored on infected devices. Many wallets allow users to protect their wallets with a series of random words. The mnemonic credentials are easier for most people to remember than the jumble of characters that appear in the private key. Words are also easier for humans to recognize in images.

Cops are now using AI to generate images of fake kids, which are helping them catch child predators online, a lawsuit filed by the state of New Mexico against Snapchat revealed this week.

According to the complaint, the New Mexico Department of Justice launched an undercover investigation in recent months to prove that Snapchat "is a primary social media platform for sharing child sexual abuse material (CSAM)" and sextortion of minors, because its "algorithm serves up children to adult predators."

As part of their probe, an investigator "set up a decoy account for a 14-year-old girl, Sexy14Heather."
