Hello, health enthusiasts! My name is Kaitlin Reilly, and I’m here to round up this week’s best wellness tips. Are you drinking less these days — or just more carefully considering how much you imbibe? If so, you’re not alone: A recent Gallup poll found that many Americans are rethinking their relationship with alcohol. Today 53% of U.S. adults say …

Millions of adults will lose at least one permanent tooth, and many will lose several more as the years go by. In the United States alone, an estimated 178 million people are missing at least one tooth, which explains why dentures and titanium implants replacements are so common. Dentistry is now aiming for something better, a living replacement that feels …

WELLINGTON, New Zealand — Long before whales were majestic, gentle giants, some of their prehistoric ancestors were tiny, weird and feral. A chance discovery of a 25 million-year-old fossil on an Australian beach has allowed paleontologists to identify a rare, entirely new species that could unlock mysteries of whale evolution. Researchers this week officially named Janjucetus dullardi, a cartoonish creature …

The newly described Janjucetus dullardi is known from juvenile remains. This illustration depicts a J. dullardi calf with its mother. (Image credit: Artwork by Ruairidh Duncan. Source: Museums Victoria) Scientists have discovered a “deceptively cute” ancient whale with large eyes and razor-sharp teeth that devoured prey off Australia around 26 million years ago. The newly discovered Janjucetus dullardi is one …

At first glance, chitons look like any other mollusk: round, bashful creatures creeping across seashore rocks. Flip one over, however, and you’ll notice rows of freakishly sharp, polished teeth—indestructible, multi-purpose chompers that researchers are seeking to replicate for the next breakthrough in material science. A new study published August 7 in Science presents a detailed investigation into what makes chiton …

Fossils unearthed along Victoria’s Surf Coast have led to the discovery of an ancient whale species with special adaptations for hunting, including large eyes and sharp teeth, shedding light on early marine mammal evolution. The species has been named Janjucetus dullardi after Victoria local resident Ross Dullard, who found the ancient whale’s fossil fragments in 2019. Janjucetus dullardi is one …

The human family tree is looking more and more like an unruly bush. Paleontologists have now uncovered the teeth of two different ancient human lineages at the same site in northeastern Ethiopia. The discovery collapses the distance between the first of our genus and the last of the australopithecines in eastern Africa. The two probably coexisted. Related: Lucy Is 50: …

“Small and deceptively cute, but definitely not harmless” is how scientists have described a new species of ancient whale, from a 25-million-year-old fossil found on Victoria’s surf coast. This early species, called Janjucetus dullardi, was an extremely unusual animal, said Dr Erich Fitzgerald, senior curator of vertebrate palaeontology at Museums Victoria Research Institute. It was tiny – about the size …

Myloplus sauron, a newly described Amazonian fish, looks like trouble at first glance. Its round silver body wears a stark black stripe that tapers toward the belly, a pattern that recalls the fiery “Eye of Sauron” from The Lord of the Rings. Yet appearances mislead. The fish is a peace loving herbivore equipped with human style molars instead of razor …

Dinosaur teeth are best known for their bite, yet new research says they also stored a chemical snapshot of prehistoric air. By probing that record, scientists have rebuilt carbon dioxide levels and plant productivity for the age of dinosaurs with a detail once thought impossible. The study comes from Dr. Dingsu Feng and colleagues at the University of Göttingen, the …
