Explanation: What does it feel like to zoom around a spinning supermassive black hole? The featured video is an animation showing a time-lapse of 4 years of observations of the star S301 orbiting Sagittarius A*, the 4-million-solar-mass black hole in the center of our Galaxy. S301 was discovered in 2023 with the Very Large Telescope Interferometer of the European Southern Observatory, located in the Atacama Desert in Chile. Astronomers recently found that S301 takes approximately 8.7 years to go around the black hole and reaches speeds of 25,000 km/s. It comes closer to the black hole than any other stars...

Navigating a world with peanut allergies can be… well, nuts. Even if you’re not the one who’s allergic. More than six million Americans have a food allergy, and peanuts are the third-most common allergen. And it doesn’t just impact those who can’t eat it: Because reactions can be deadly, peanut-free policies and other restrictions are common in places like schools and restaurants. But a Minnesota-based startup is developing a new “hypoallergenic” peanut that could bring the salty snack back to hospitals, planes, cafeterias and restaurants without causing allergic reactions. Nurtured Nuts CEO Bryant Williams sought to remove three of the...

Colorado state officials on Thursday morning released the results of spring 2023 K-12 achievement tests and the results are mixed -- suggesting that where students were developmentally when their learning was disrupted by the COVID pandemic may play a role in how well they're succeeding academically today. In the English Language Arts portion of the Colorado Measures of Academic Success for example, higher percentages of students in grades 5, 6 and 7 met or exceeded expectations than in 2022, but grades 3 and 4 saw drops or nominal gains. The CMAS tests students in grades 3-8, finding that across the...

Former first lady Jill Biden doubled down on the possibility of her husband, former President Joe Biden, being drugged ahead of the 2024 debate and was asked during a podcast Thursday whether doctors ruled out a stroke that night. Podcast host Jamie Kern Lima asked Biden if a stroke was ruled out by doctors the night of the debate. “Well, they did. They said, I mean, I didn’t say to them, when I was writing my book, I was reflecting, but I didn’t say, ‘God, did Joe have a stroke?’ I just said, ‘Is he OK? Is he OK?'” Biden...

MOST PEOPLE believe humans are different. The reason is that Homo sapiens has evolved to be conscious. Many animals feel pain and pleasure; some appear to be self-aware. But the human mind’s unique potential to exhibit a sense of self marks out every member of the species for special treatment. In his encyclical in May, Pope Leo upheld this insight by drawing a line between humanity and its growing army of bots. Artificial-intelligence systems, he said, do not undergo experiences or feel joy or pain. He is not alone. Many people feel that to confer personhood on AIs would be...

WASHINGTON — They’re a shady bunch. A California family that swindled $18 million in COVID-19 relief cash to splurge on various trappings — including a Harley-Davidson, diamonds and luxury homes — inspired a Senate crackdown on so-called “fraudster families.” Two of the family members, Richard Ayvazyan and his wife, Marietta Terabelian, cut off their ankle bracelets and ditched their three children via a goodbye note to flee the US after being convicted on fraud charges, before being caught in Montenegro. Years later, the saga inspired Sen. Joni Ernst (R-Iowa), who has led the Senate DOGE Caucus, to push for legislation...

Explanation: Like an illustration in a galactic Just So Story, the Elephant's Trunk Nebula winds through the emission region and young star cluster complex IC 1396, in the high and far off constellation of Cepheus. Also known as vdB 142, this cosmic elephant's trunk is over 20 light-years long. The detailed telescopic view features the bright swept-back ridges and pockets of cool interstellar dust and gas that abound in the region. But the dark, tendril-shaped clouds contain the raw material for star formation and hide protostars within. Nearly 3,000 light-years distant, the relatively faint IC 1396 complex covers a large...

In the second century A.D., Roman emperor Hadrian commissioned a temple dedicated to the gods. To this day, the Pantheon still possesses the largest unreinforced concrete dome in the world. How do these ancient Roman concrete structures withstand the test of time? Well, superior engineering for one. For example, skilled artisans used lighter aggregates higher in the Pantheon's dome. Roman seawalls owe their extreme longevity in part to their “self-healing” capacity. Exposure to seawater facilitated the continued growth of crystalline structures in the concrete. Researchers have also focused on volcanic ash as a secret to the durability of Roman concrete...

The US is at a heightened risk of a catastrophic blackout that could last up to 18 months due to aging power grid infrastructure that takes agonizingly long to update and is potentially vulnerable to a precision weapon strike. The alarming vulnerability was brought to light in 2013 by Jon Wellinghoff, former chair of the Federal Energy Regulatory Commission (FERC), after a coordinated attack on a California electrical substation in April 2013. The gunmen fired 120 shots, taking out an alarming 17 transformers at a Pacific Gas and Electric’s Metcalf electrical substation just outside San Jose, New York Times Magazine...

Moderna stock more than doubled Wednesday after the biotechnology company and Merck announced that their personalized mRNA cancer vaccine significantly delayed the return and spread of melanoma in a late-stage clinical trial. The breakthrough could give Moderna its most important commercial opportunity since COVID-19, strengthen Merck’s dominant Keytruda franchise and open the door to an entirely new class of individualized cancer treatments. However, investors should recognize that the companies have released only topline results, while detailed efficacy data, regulatory decisions, manufacturing economics and overall-survival results remain outstanding.Moderna’s long-promised second act may finally be coming into focus.Shares of Moderna jumped approximately...

Explanation: Whatdunit? What disappeared while crossing a partially eclipsed Sun? Let’s present the evidence. The 24 frames-per-second video was taken in Spain (40°34'30.3"N 1°12'28.8"W) at 20:28 local time on August 12, 2026. The Perseids meteor shower was at its peak during this time. Is this a meteor? Meteor showers trace back to a region of the sky called a radiant point that corresponds to where the Earth is crossing a comet’s path. The object’s path might trace back to the Perseids’ radiant point in the Perseus constellation. The object trails a smaller angle on the sky than the 0.5 degree...

Shares of Merck (MRK) and Moderna (MRNA) spiked in the premarket on Wednesday after the companies said that their jointly developed messenger RNA-based cancer therapy, intismeran autogene, succeeded in a late-stage trial for patients with melanoma, a type of skin cancer. The Phase 3 INTerpath-001 trial was designed to evaluate intismeran in combination with Merck's (MRK) blockbuster anti-PD-1 therapy Keytruda in more than 1,100 patients with stage IIB-IV melanoma whose cancer has been completely resected. According to its topline data, INTerpath-001 met its primary endpoint of recurrence-free survival and a secondary endpoint of distant metastasis-free survival, marking the first late-stage...

A NASA spacecraft circling the moon is providing the sharpest views yet of the crater carved by a crashing SpaceX rocket. The space agency released before-and-after photos of the impact area on Tuesday. The Falcon rocket’s upper stage plowed into the moon at 5,400 mph on Aug. 5 after drifting through space for more than a year. It launched a pair of private moon landers with experiments and even a tiny rover in 2025 as part of NASA’s push to commercialize lunar exploration. Based on these new photos by NASA’s Lunar Reconnaissance Orbiter, the fresh crater appears to be 60...

Explanation: This was a good year for the Perseids meteor shower. A key reason was the Moon was absent from lighting up Earth's night sky so that more meteors were visible than usual. Where was the Moon? It was busy visiting the Sun. Near the Perseids peak, the Moon moved directly in front of the Sun and created a total solar eclipse visible from Greenland and Spain. The Perseids occur when the Earth collides with a stream of Sun-orbiting debris cast off by Comet Swift-Tuttle. Perseid meteors, although typically only the size of a sand grain, tend to be fast...

Around 8,500 years ago, Mesolithic hunter-gatherers were living on the tiny islands of Malta -- thousands of years after the islands had become separated from Sicily. The shortest sea crossing was around 80 kilometres. So how did these prehistoric seafarers get there, and how could such a small population survive on Malta for around a thousand years?

At Kimmeridge Bay [Dorset, UK] on the Jurassic Coast, the rocks have a bit of a pattern to them. And there's a good reason for that! It's a record of changes in Earth’s climate that were driven by something happening far beyond Dorset: the changing geometry of Earth’s orbit around the Sun... Because Earth's orbit changes over time in cycles! Welcome to Milancovich cycles! This is far from the only rock unit that shows this, and in fact the Blue Lias around Lyme Regis is also pretty famous for this, but I found this cool paper that really investigated it...

Readers of my previous (August 13) post on the Endangerment Finding (EF) litigation pending in the D.C. Circuit may have come away wondering about this issue: What is the basis on which this coalition of most blue states plus many major municipalities and big-time environmental NGOs seeks to put an indefinite stall on resolution of the litigation? As reported in that post, after the Trump EPA had finalized its rescission of the EF in February 2026, a large number of blue states, municipalities and environmental NGOs promptly filed Petitions in the D.C. Circuit seeking to have the court block that...

There is only so much capacity in space for objects; a cleanup is critical and overdue. Satellites bring to mind images of shiny, angular objects orbiting Earth at tremendous speed through the boundless emptiness of space. Yet the orbits are no longer empty. Besides traffic, they are teeming with debris from spacecraft breaking up because of age, explosions, or collisions. Orbital debris has doubled over the past decade. As of 2026, about 1.2 million objects measuring 1–10 cm are in orbit. Traveling at speeds of 7–8 km per second—10 times that of a bullet and 4–5 times that of the...

California gubernatorial candidate Xavier Becerra has claimed he will slash people’s utility bills by granting two hours of free electricity per day — a plan his rival has blasted as “disqualifyingly stupid.” The Democrat unveiled his new policy pitch on Tuesday to give the handout to lower-income families, though he failed to lay out how it would be designed or funded. The so-called “power hour” plan comes as Californians struggle with the state’s increasingly high cost of living. Part of that crisis includes skyrocketing energy bills, which his opponent, Republican Steve Hilton, has also targeted. Californians have seen their energy...

Don’t believe the Democratic National Committee’s official storyline: The DNC’s decision to make South Carolina the first Democratic presidential primary in 2028 isn’t about introducing more racial diversity into the early contests. It’s actually about keeping power in the hands of the party establishment — the people who backed Hillary Clinton in 2016 and Joe Biden in 2020, and who are likely to wind up supporting Kamala Harris in 2028. The fix is in. South Carolina was the establishment’s firewall against Bernie Sanders’ left-wing insurgency twice over. In 2016, Sanders nearly beat Hillary Clinton in the first caucus, in Iowa,...
