And it’s time to bid farewell to one of the most delightfully plucky robots ever to explore Mars. Other worldsThe Ingenuity helicopter, seen here on Mars in an image taken by the Perseverance rover on August 2, 2023, has flown for the last time. Ingenuity served as the Perseverance rover’s faithful companion and aerial scout for nearly three years since its maiden flight on April 19, 2021. A long time agoAiming to trace syphilis' origins, researchers used paleopathology techniques to study ancient human bones at the site Jabuticabeira II in Brazil's Santa Catarina state. They find wonder in planets beyond our solar system and discoveries from the ancient world.

☆ Megalodons were skinnier than we previously thought, new study suggests
▼ + stars: | 2024-01-22 | by ( Jack Guy | ) edition.cnn.com time to read: +5 min

CNN —Megalodons, the huge prehistoric sharks depicted in movies such as “The Meg,” had more slender bodies than was previously thought, according to a new study. Many mysteries remain about the biology of megalodons, but until now, great white sharks had been used to model their appearance. The dark grey silhouette depicts the previously reconstructed body form, based on the great white shark. Kenshu Shimada/DePaul UniversityThis new research is based on the reappraisal of an incomplete set of fossil vertebrae found in Belgium. The research suggests that “the modern great white shark may not necessarily serve as a good modern analog for assessing at least certain aspects” of megalodon biology, said Shimada.

☆ Opinion: What nearly every human seems to be missing about shark attacks
▼ + stars: | 2023-08-10 | by ( Opinion Holly Thomas | ) edition.cnn.com time to read: +5 min

For the unlucky few who experience shark attacks, the ordeal is undoubtedly terrifying. Yet every summer, stories about shark attacks top homepages. Unlike shark attacks on humans, which are mainly attributed to curiosity, we know exactly what we’re doing. Throughout, the great white is characterized as a dogged predator obsessed with human flesh. I’d never suggest that the victims of shark attacks had it coming, or that cinemagoers should feel an iota of shame.

☆ Ancient regal tomb in Spain belonged to a revered female leader, archaeologists reveal

While analysis of DNA is one factor, archaeologists have relied on other clues to gain insight, such as grave goods. European archaeologists made a “spectacular” find in 2008 of a tomb near Seville, Spain, that belonged to an ancient individual of great importance. The Ivory Lady, who possibly held a leadership role, was likely revered by her society for generations after she died. Defying gravityThe Perseverance rover snapped a new image of the Ingenuity helicopter on Mars on April 16. As Ingenuity and the Perseverance rover begin to explore more challenging terrain, obstacles can block communications between the two — and Perseverance is the only one that can “call” Earth.

☆ Scientists find new clue in what led to megalodon’s demise
▼ + stars: | 2023-07-03 | by ( Amaya Mcdonald | ) edition.cnn.com time to read: +4 min

Scientists previously theorized that megalodons were warm-blooded, but the new study is the first to provide concrete evidence to that effect. From this finding, they deduced the megalodon’s average body temperature was about 27 C (80 F). Like modern great white and mako sharks, megalodons were regionally endothermic, which means they had the ability to regulate temperature in certain parts of the body, according to the study. The timing of megalodons’ extinction coincides with the cooling of the Earth’s temperature, the researchers said. But learning more about the ancient shark could still help scientists better understand the threats similar marine animals face today.

A charter boat captain found a whopping 6.25-inch long megalodon shark tooth in Florida. That's why today, the Sarasota County coastline in Venice, Florida, is known as the shark tooth capital of the world. Recently, a charter boat captain discovered one of the largest fossilized shark teeth ever from a megalodon shark. One of the largest megalodon teeth ever discoveredMichael Nastasio, who has been hunting shark teeth in Florida for 12 years, discovered a fully-intact megalodon shark tooth that was 6.25 inches (15.87 cm) long — only about an inch smaller than the largest megalodon tooth on record. Megalodon teeth are similar to great white shark teeth, and it's thought the two species may have been close relatives.

☆ Scan finds megalodon tooth necklace in Titanic wreck

CNN —A necklace carrying the tooth of a prehistoric shark known as a megalodon has been discovered in the wreckage of the Titanic during a digital scan of the sunken ship. For more than 100 years, the necklace has sat at the bottom of the ocean following the sinking of the Titanic in 1912, according to Magellan, a deep water investigation company that carried out the scan. Images from the scan show a gold necklace with a tooth of a megalodon, scientifically known as Otodus megalodon, a prehistoric shark that lived more than 23 million years ago. The necklace was discovered by Magellan during a project to produce a full-size digital scan of the Titanic, which the company says is the largest underwater scanning project in history. The megalodon tooth necklace is pictured in the center of this image.

☆ Summer movie preview 2023

CNN —Most moviegoers can pinpoint one summer movie – or perhaps, a summer of movies – in their formative years that really and truly cemented their love for going to the cinema, whether it be 1975’s “Jaws,” “E.T. And while streaming has clearly siphoned off part of the audience, particularly for more serious films, what we think of as “summer movies” still have the potential to rake in cash just like the old days. (CNN and DC are both part of the same parent company, Warner Bros. Courtesy Warner Bros. PicturesInitially meant for streaming platforms, this vehicle will herald the cinematic arrival of DC Studios’ first Latino superhero, played by Xolo Maridueña of “Cobra Kai” and “Parenthood” fame. If the fast-paced trailer is any indication, the movie looks sure to whisk those dog days of summer doldrums away quite nicely.

☆ 9 things about sharks you saw in movies that are actually wrong, according to an expert

Here are facts that "Jaws," "Finding Nemo," and "The Meg" got wrong — and one that's right. NOAA fisheriesIt's those scales that make the shark nose the wrong target for a sucker punch. When Dory hits her nose, her blood goes straight into the shark's nose. So "Finding Nemo" hit the nail on the head when they showed blood actually going into the shark's nose, she said. Gerard Soury/Getty ImagesSharks in "Finding Nemo" might want to fight their urges to eat fish, but it's not in their nature.

În vârstă de 25 de ani, Jeffrey Heim a crezut inițial că a fost lovit de o elice de barcă, până a observat aligatorul care se uita la el. Bărbatul spune că a glumit pe seama evenimentului, dar a conștientizat prin ce a trecut când a ajuns la spital. Înainte de a face o tomografie computerizată, el și-a dat seama cât de norocos a fost că a supraviețuit acestui atac. O femelă aligator de peste 6 metri a fost capturată în zonă, iar o capcană a fost pusă pentru prinderea unui alt aligator din apropiere.
