Sawfish fossils suggest teeth likely evolved from body scales in ancient fish
Scientists have long debated the origins of teeth. Did they evolve from body scales that migrated into the mouths of ancient vertebrates and became adapted for eating—an idea known as the "outside-in" hypothesis? Or did they evolve independent of s.....»»
Researchers show nanoplastics can reduce the effectiveness of antibiotics
In a recent study, an international research team with significant involvement from MedUni Vienna has investigated how nanoplastic particles deposited in the body affect the effectiveness of antibiotics......»»
How life began on Earth: Modeling the ancient atmosphere
The key to unlocking the secrets of distant planets starts right here on Earth. Researchers at Tohoku University, the University of Tokyo, and Hokkaido University have developed a model that considers various atmospheric chemical reactions to estimat.....»»
Compact in-incubator imaging device allows real-time remote monitoring of cell growth
Unlike most cells in the human body, stem cells have the unique ability to divide indefinitely. This property makes them especially appealing to scientists exploring ways to extend human lifespans or develop new methods for repairing damaged tissues......»»
A Lost Mayan City Has Been Found With Laser Mapping
Archaeologists have revealed an ancient lost Mayan city using advanced laser mapping technology, unearthing monumental structures such as pyramids and plazas. Named Valeriana, the city is believed to have been founded before 150 AD......»»
Volcanic "cryptic carbon" emissions may be a hidden driver of Earth"s past climate
An international team of geoscientists led by a volcanologist at Rutgers University-New Brunswick has discovered that, contrary to present scientific understanding, ancient volcanoes continued to spew carbon dioxide into the atmosphere from deep with.....»»
How harmful are microplastics to human health?
Microplastics have been found throughout the human body -- including inside lungs, blood and brains -- and while it is not yet clear how harmful they are to our health, some researchers are sounding the alarm......»»
African giant rats trained to sniff out illegal wildlife products
In the past, African giant pouched rats have learned to detect explosives and the tuberculosis-causing pathogen. Now, a team of researchers have trained these rats to pick up the scent of pangolin scales, elephant ivory, rhino horn, and African black.....»»
Ecologists suggest animal alcohol consumption more common than thought
Anecdotes abound of wildlife behaving "drunk" after eating fermented fruits, but despite this, nonhuman consumption of ethanol has been assumed to be rare and accidental. Ecologists challenge this assumption in a review published October 30 in Trends.....»»
Sinuses prevented prehistoric crocodile relatives from deep diving, paleobiologists suggest
An international team of paleobiologists have found that the sinuses of ocean-dwelling relatives of modern-day crocodiles prevented them from evolving into deep divers like whales and dolphins......»»

An ancient temple made by Arabian immigrants from the Nabataean culture has finally been found off the Italian coast.....»»
Oceanographers record the largest predation event ever observed in the ocean
There is power in numbers, or so the saying goes. But in the ocean, scientists are finding that fish that group together don't necessarily survive together. In some cases, the more fish there are, the larger a target they make for predators......»»
From fish to clean water, the ocean matters—how to quantify the benefits
Nature protection, conservation and restoration is "not a trivial matter but key to human survival," according to scientists quoted in a 2005 UN report. To demonstrate this, they developed the concept of "ecosystem services"—the benefits that peopl.....»»
Lidar mapping reveals mountainous medieval cities along the Silk Road
A city larger than many in Europe at the time was perched in the mountains. The history of the Silk Road, a vast network of ancient and medieval trade routes connecting Beijing an.....»»
Tracking a disappearing mantle plume in ancient Samoa: Researchers shed light on a 30-million-year gap
When plumes of magma well up through Earth's lithosphere, they create volcanoes, islands, seamounts, and other features on the surface. Telltale hot spot tracks form as tectonic plates move over these plumes, marking plume locations and the movement.....»»
Dinosaurs thrived after ice, not fire, says a new study of ancient volcanism
201.6 million years ago, one of the Earth's five great mass extinctions took place, when three-quarters of all living species suddenly disappeared. The wipeout coincided with massive volcanic eruptions that split apart Pangaea, a giant continent then.....»»
