By Ashley Strickland, CNN (CNN) — When scientists attached a tag to a pregnant porbeagle shark in October 2020 to learn more about the creature’s habitat, they didn’t expect their tracker to capture evidence of how large sharks hunt one another. But when the tracker registered some unexpected activity in March 2021, the scientists realized

By Laura Paddison, CNN (CNN) — Summer broke global heat records for the second straight year, scientists have confirmed — putting 2024 firmly on track to be the hottest year in recorded history. The period between June and August — summer in the Northern Hemisphere — was the world’s hottest such period since records began

By Katie Hunt, CNN (CNN) — In H.G. Wells’ 1897 science fiction novel, “The Invisible Man,” the protagonist invents a serum that makes the cells in his body transparent by controlling how they bend light. More than 100 years later, scientists have discovered a real-life version of the substance: A commonly used food coloring found

By Ashley Strickland, CNN (CNN) — Jupiter’s moon Ganymede may have shifted on its axis when a massive asteroid smashed into it about 4 billion years ago, according to a new study. Ganymede, the largest moon in the solar system, is even bigger than Mercury and the dwarf planet Pluto. And past research has found

By Radina Gigova, CNN London (CNN) — A “remarkable” Pictish ring with “an intricate setting” was discovered in Scotland by an amateur archaeologist after being buried for more than 1,000 years. The “kite-shaped ring with a garnet or red glass center” was unearthed by a volunteer at the site of a fort in Burghead, in

By Monica Garrett and Steve Tuemmler, CNN (CNN) — A roughly 1-meter (3-foot) asteroid burned up in Earth’s atmosphere over the Philippines near Luzon Island early Wednesday afternoon, according to NASA. The European Space Agency estimated the impact occurred at 12:39 p.m. ET (4:39 p.m. UTC). The Catalina Sky Survey discovered the object, initially called

By Katie Hunt, CNN (CNN) — A wheeled bot rolls across the floor. A soft-bodied robotic star bends its five legs, moving with an awkward shuffle. Powered by conventional electricity via plug or battery, these simple robotic creations would be unremarkable, but what sets these two robots apart is that they are controlled by a

By Laura Paddison, CNN (CNN) — A team of NASA rocket scientists is developing autonomous underwater robots able to go where humans cannot, deep beneath Antarctica’s giant ice shelves. The robots’ task is to better understand how rapidly ice is melting — and how quickly that could cause catastrophic sea level rise. In March, scientists

By Amarachi Orie, CNN (CNN) — In the years since the Titanic sank after hitting an iceberg in 1912, we have become familiar with haunting images of the doomed passenger liner’s bow, lying at the bottom of the North Atlantic Ocean. Now, new photos taken this summer show that the view has changed dramatically. The

By Rachel Ramirez, CNN (CNN) — The largest dam removal project in US history is finally complete, after crews last week demolished the last of the four dams on the Klamath River. It’s a significant win for tribal nations on the Oregon-California border who for decades have fought to restore the river back to its natural

By Katie Hunt, CNN (CNN) — What lies beneath the waves is among the planet’s biggest mysteries. About half of Earth’s surface remains unknown and unexplored. That’s because humans have mapped only a quarter of the seafloor, which covers around 70% of the planet, to a high resolution. But how do you find what you

By Ashley Strickland, CNN (CNN) — Rocky debris blasted away from the tiny asteroid Dimorphos when NASA’s DART spacecraft intentionally slammed into it in 2022 could create the first human-made meteor shower known as the Dimorphids, new study has found. The space agency planned the DART, or Double Asteroid Redirection Test, mission to carry out

By Jackie Wattles, CNN (CNN) — The world’s most frequently launched rocket — the SpaceX Falcon 9 — is cleared to fly again, federal regulators announced Friday evening, putting the vehicle back on track for two high-profile human spaceflight missions. The Federal Aviation Administration, which licenses commercial rocket launches, grounded SpaceX’s rocket on August 28,

By Lianne Kolirin, CNN (CNN) — Marmosets can communicate with one another by name and know when they are being addressed, joining a very short list of species exhibiting such behavior, and a first for non-human primates, a new study has found. The monkeys use specific calls, known as “phee-calls,” to call each other, which

By Ashley Strickland, CNN (CNN) — An ancient, submerged bridge in a cave on the Spanish island of Mallorca is helping researchers determine when humans first settled on islands across the western Mediterranean Sea thousands of years ago. A new analysis of the 25-foot-long (7.6-meter-long) bridge inside Genovesa Cave has revealed that humans lived on

By Jackie Wattles, CNN (CNN) — After 12 weeks in space, Boeing’s Starliner spacecraft is finally set to return home from the International Space Station on September 6 — albeit without its two-person crew. The troubled spacecraft will undock from the orbiting laboratory around 6 p.m. ET, and it will spend about six hours maneuvering

By Katie Hunt, CNN (CNN) — A rare fossil has provided a snapshot of what was an exceptionally unlucky day for a prehistoric sea cow. The now-extinct species of dugong, a manatee-like marine mammal, was swimming in the sea about 15 million years ago when it was preyed upon by two animals: a crocodile and a
