Explanation: To see the feathered serpent descend the Mayan pyramid requires exquisite timing. You must visit El Castillo -- in Mexico's Yucatán Peninsula -- near an equinox. Then, during the late afternoon if the sky is clear, the pyramid's own shadows create triangles that merge into the famous illusion of a slithering viper. Also known as the Temple of Kukulkan, the impressive step-pyramid stands 30 meters tall and 55 meters wide at the base. Built up as a series of square terraces by the pre-Columbian civilization between the 9th and 12th century, the structure can be used as a calendar...

...the idea behind the Leonardo da Vinci DNA Project, which aims to accurately answer a simple question: since we couldn't sequence Leonardo's DNA in the 1500s, are his bones at Amboise Castle really his?To get there, the team plans to compare DNA from Leonardo's remains with profiles from his living relatives -- and, if the samples check out, assemble more of Leonardo's genome.Because the legendary Renaissance artist had no children, researchers Alessandro Vezzosi and Agnese Sabato of the Leonardo Da Vinci Heritage Association started with old-school genealogy, publishing Genìa Da Vinci. Genealogy and Genetics for Leonardo's DNA. Their tree follows...

Kamala Harris is cutting California loose from her book tour, cancelling the remainder of her currently scheduled stops in the state. On Tuesday, the former presidential candidate pulled out of book tour stops for her memoir “107 Days” in Sacramento, San Diego and Anaheim. The appearances had been scheduled for next month. Ticketing company Ticketmaster refunded ticketholders and explained that the cancellations of “A Conversation with Kamala Harris” were due to a “scheduling conflict.” Harris’ last event had been in Oakland on March 3. She remains scheduled for an event in Denver, Colorado, on April 2, but her subsequent stops...

The designers behind Hollywood’s grandest stage pulled back the curtain on their green-themed inspiration for the Oscars dais. The stage for the 98th Academy Awards show resembles a garden courtyard, with overhanging tree branches and other floral touches meant to provide a feeling of zen. “There is an unsettled nature around the climate right now, and there’s just something very calming about being surrounded by architecture, but having this space for trees to grow,” Oscars production designer Alana Billingsley told Vanity Fair of the stage’s theme. The stage for the 98th Academy Awards show resembles a garden courtyard, with overhanging...

Live Science reports that about 30 inscriptions written in three ancient Indian languages have been studied in six different tombs in Egypt’s Valley of the Kings. Ingo Strauch of the University of Lausanne said that these inscriptions have been dated to between the first and third centuries A.D., when Egypt was a province of the Roman Empire and a tourist destination. One inscription, written in Sanskrit, was left by a man named Indranandin, who identified himself as a messenger of King Kshaharata. "It is possible that Indranandin arrived by ship at Berenike [on the east coast of Egypt], perhaps together...

Oil pumping operations are expected to begin imminently off the coast of California after President Trump issued an executive order Friday to resume oil drilling operations near Santa Barbara, The Post has learned. Officials for Sable Offshore Corp. informed local fire officials of their intent to “resume pumping operations within 24 hours.” The notification is a standard protocol for industrial activities involving hazardous materials pipelines. “This coordination allows the department to maintain readiness for potential emergency response, including resource staging, personnel alerting, and collaboration with other agencies, in the event of any incident such as a leak, spill, or fire,”...

Explanation: Want to visit a planet that has 3.14 days in a year? Then plan a trip to K2-315b, an earth-sized planet orbiting around a cool, red, M dwarf star about once every 3.14 days. The exoplanet's discovery, based on publicly available data from the planet-hunting Kepler Space Telescope's extended K2 mission, was announced in 2020. K2-315b's measured orbital period in days is nearly equal to the extremely popular irrational number Pi. That puts the exoplanet so close to its parent star that its surface is likely very warm, baking-hot in fact. And this Pi planet is over 185 light-years...

According to a statement released by the University of New Hampshire, Meghan Howey and Michael Palace of the University of New Hampshire compared temperature data collected by Landsat 8 satellite thermal sensor between 2014 and 2024 and the locations of burial mounds built between A.D. 1200 and 1600 in what is now Michigan’s Lower Peninsula. The researchers discovered that the Anishinaabeg, who lived in the Great Lakes area, built burial mounds near more circular-shaped lakes that warmed later in spring and cooled later in fall. Placement of the mounds may therefore have been associated with a longer maize growing season,...

Explanation: In this composited night skyscape, stacked exposures trace graceful star trails above Lake Toolondo, Victoria, Australia, planet Earth. Captured while the lunar eclipse of March 3 was in progress, the exposures used were made during the hour-long total eclipse phase. So faint star trails are easily visible along with the trail of the reddened Moon in the eclipse-darkened skies above the lake and trees. Of course, the apparent motion of Moon and stars revealed in the timelapse composite reflect the Earth's daily rotation around its axis. Dramatically punctuating the Moon's trail as totality ended, a single, separate telephoto image...

According to a statement released by the Nature Publishing Group, Anopheles leucosphyrus mosquitoes may have evolved to feed on humans in Southeast Asia. Upasana Shyamsunder Singh of Vanderbilt University, Catherine Walton of the University of Manchester, and their colleagues sequenced DNA from 38 modern-day mosquitoes from 11 species in the leucosphyrus group. Then the researchers employed computer models and estimates of DNA mutation rates to reconstruct the evolution of these mosquitoes. The study suggests that the bugs switched from feeding on non-human primates to early humans in the region of Sundaland, an area including the Malay Peninsula, Borneo, Sumatra, and...

Tradition holds that the eldest son of Genghis Khan, ruler of the Mongol Empire, founded the Golden Horde and was buried in Kazakhstan with his descendants. According to a statement released by the University of Wisconsin–Madison (UW–Madison), an international team of researchers led by Ayken Askapuli of UW–Madison analyzed genomes taken from remains found in four Golden Horde tombs in Kazakhstan, and determined that their ancestors could be traced to the Mongolian plateau through their Y-chromosomes. “We saw evidence that their Y-chromosomes are part of a branch of the C3* cluster,” Askapuli said. Some 20 years ago, fragments of DNA...

The “Melania” documentary about first lady Melania Trump debuted at the top of Amazon Prime’s streaming charts after premiering earlier this week. The documentary, which follows 20 days in the first lady’s life before President Donald Trump’s second term in office, hit the streaming service Monday. Just one day after its premiere, “Melania” became the most-streamed film on the platform and the most-streamed content overall in the United States, according to Flix Patrol. The first lady celebrated the feat in a post on X Tuesday. As of Thursday, the film is the third most-streamed overall behind the Amazon Prime series...

A flying taxi took a spin over San Francisco Thursday — and the Bay Area’s tech crowd was there to watch. The small electric aircraft from Joby Aviation flew across San Francisco Bay near the Golden Gate Bridge during a demonstration flight that drew reporters and industry guests to the St. Francis Yacht Club. The flight is part of the company’s push to launch electric air taxis — small vertical takeoff planes designed to carry passengers on short trips of roughly 10 to 50 miles. Joby’s aircraft seats four passengers and uses six propellers. The company says rides could cost...

For around 700 years, Native people of the American Great Plains hunted bison at a site in central Montana that archaeologists call Bergstrom. Then, around 1,100 years ago, humans abandoned the site even though bison remained abundant in the area, according to a statement released by Frontiers. "The Bergstrom site presented a puzzle," paleoecologist John Wendt of New Mexico State University said. "Why would hunters stop using a site that had worked for so long?" In 2019, Wendt's team began digging and investigating three-foot-by-three-foot excavation pits to try to better understand the Bergstrom site's use and eventual disuse. Researchers collected...

Explanation: For the first time we are witnessing outer planet Uranus take center stage and pirouette. Uranus is one of the Solar System’s strangest planets, lying on its side and spinning like a rotisserie chicken. The featured video is composed of over 1000 spectra taken over 15 hours of continuous viewing by JWST's NIRSpec instrument while Uranus rotates. The data captures the behavior of Uranus’s ionosphere: the ionized layer of a planet’s atmosphere that strongly interacts with the planet's magnetic field. The aurora’s rosy glow traces the complex interplay between Uranus's misaligned rotation and magnetic axes. Clouds can be seen...

WASHINGTON — The White House is privately pushing congressional lawmakers to keep their cool as the war in Iran wraps up its 12th day, arguing it is critical to root out threats from the Islamic Republic against the US and its allies. The message from the White House to jittery Republicans is that the “short-term spike” at the pump is needed for a “long-term gain,” a White House official told The Post. While Republicans in Congress are largely cheering on President Trump’s military campaign in Iran — at least publicly — many of them are anticipating fallout and potential midterm...

Giants co-owner Steve Tisch announced he will give up his shares of the football team and pass them on to his children after being exposed for asking Jeffrey Epstein about a “working girl” in a series of damning emails about women, sources confirmed to The Post. Tisch, 77, requested to transfer the 23.1% stake in Big Blue that he shares with his siblings, Laurie and Jonathan, to his and their children. The move would leave the elder Tisch siblings with no ownership of the team if the NFL’s finance committee approved the move, first reported by ESPN. The team is...

Explanation: Is this a cosmic monster ready to devour an unsuspecting galaxy? Thankfully, that is not the case. The red “monster” shown in the featured image is Cometary Globule CG 4, 1,300 light-years away in the Constellation Puppis. CG 4 is a molecular cloud, where hydrogen becomes cold enough to form molecules that can be brought together by gravity to create stars. The shape of CG 4 resembles that of a comet, but its head is 1.5 light-year in diameter and its tail is 8 light-years long; for comparison, the distance from the Earth to the sun is only 8...
