Ancient megalodon super-predators could swallow a great white shark whole, new model reveals

The reconstructed megadolon was 16 meters long and weighed over 61 tons. Credit: JJ Giraldo In a new 3D modeling study published this week in Science Advances, we show that the giant extinct shark, Otodus megalodonwas a true globetrotting super-predator. It was capable of covering vast distances in short order, and could eat the largest … Read more

Future-proofing the Great Lakes region through climate research

Credit: Unsplash/CC0 Public Domain Researchers are studying the way warming water temperatures will impact the Great Lakes region. Their work shows that small differences in lake surface temperatures can have a big impact on summer climate and can fuel extreme weather—crucial information. The Great Lakes have a profound impact on the country’s identity, economy and … Read more

Protecting 30% of Australia’s land and sea by 2030 sounds great, but it’s not what it seems

A grim story of “crisis and decline” was how Environment Minister Tanya Plibersek described the situation when she launched the State of … Read more

Shark Week, the ‘Jaws effect’ and how more great whites in the water are changing human behavior

Credit: Evan Prasky Cape Cod resident Doug Fraser realized he had made the right decision to give up boogie boarding in favor of a standup paddle board the day a great white shark swam under him and rolled over to take a closer look. From his standing position on the paddle board, Fraser was able … Read more

The best offense is a great defense for some carnivorous plants

Credit: Pixabay/CC0 Public Domain Insect-eating plants have fascinated biologists for more than a century, but how plants evolved the ability to capture and consume live prey has largely remained a mystery. Now, Salk scientists, along with collaborators from Washington University in St. Louis, have investigated the molecular basis of plant carnivory and found evidence that … Read more

Great white sharks may have contributed to megalodon extinction

Tooth size comparison between extinct Early Pliocene Otodus megalodon tooth and a modern great white shark. Credit: © MPI for Evolutionary Anthropology The diet of fossil extinction animals can hold clues to their lifestyle, behavior, evolution and ultimately extinction. However, studying an animal’s diet after millions of years is difficult due to the poor preservation … Read more

Betelgeuse’s ‘Great Dimming’ had an unlikely observer: a Japanese weather satellite

Astronomers have a new way to study stars: take advantage of meteorological satellites orbiting Earth. That’s the conclusion of a new paper that presents new data from a Japanese weather satellite that just so happened to observe the red supergiant star Betelgeuse during a period of inexplicable dimming. The serendipitous observations could mean a new … Read more

Most Great Barrier Reef coral studied this year was bleached

In this photo supplied by the Great Barrier Reef Marine Park Authority (GBRMPA), a diver swims past coral on the Great Barrier Reef in Australia, Oct. 18, 2016. More than 90% of Great Barrier Reef coral surveyed in 2022 was bleached in the fourth such mass event in seven years in the world’s largest coral … Read more
