Researchers Generate a Family Tree for Living and Extinct Snakes

A team of researchers from Yale University analyzed snake genomes, modern snake anatomy, and information from the fossil record, generating a family tree for living and extinct snakes and illuminating major evolutionary patterns that have played out across snake evolutionary history. The ancestral snakes in the grass actually lived in the forest, according to the […]

The Hubbard Glacier

New data from the Operational Land Imager on Landsat 8 shows the advance of Hubbard Glacier. Since measurements began in 1895, Alaska’s Hubbard Glacier has been thickening and steadily advancing into Disenchantment Bay. The advance runs counter to so many thinning and retreating glaciers nearby in Alaska and around the world. This image, acquired by […]

Researchers Explain Mystery of India’s Rapid Move Toward Eurasia

A newly published study from MIT geologists reveals that a double subduction system may have driven India to drift at high speed toward Eurasia some 80 million years ago. In the history of continental drift, India has been a mysterious record-holder. More than 140 million years ago, India was part of an immense supercontinent called […]

A Crucial Difference in the Fingerprints of Earth and the Moon

A newly published study brings scientists one step closer to understanding the close familial relationship between Earth and the moon. College Park, Maryland – Scientists at the University of Maryland are the first to confirm the accepted model of the moon’s formation using the “fingerprints” of the moon and Earth. The results suggest that the […]

Life Could Have Flourished on Earth 3.2 Billion Years Ago

New research from the University of Washington found evidence that life was pulling nitrogen out of the air and converting it into a form that could support larger communities 3.2 billion years ago. A spark from a lightning bolt, interstellar dust, or a subsea volcano could have triggered the very first life on Earth. But […]

Yarlung Tsangpo Valley close to the Tsangpo Gorge

The new discovery a deep canyon buried along the Yarlung Tsangpo River in south Tibet effectively rules out a popular model used to explain how the massive and picturesque gorges of the Himalayas became so steep, so fast. A team of researchers from Caltech and the China Earthquake Administration has discovered an ancient, deep canyon […]

Earth's Water Most Likely Accreted at the Same Time as the Rock

New research from Woods Hole Oceanographic Institution shows that Earth’s water most likely accreted at the same time as the rock, suggesting that Earth received most of its water relatively early from chondrite-like bodies. Earth is known as the Blue Planet because of its oceans, which cover more than 70 percent of the planet’s surface […]

Low Oxygen Levels Delayed the Appearance of Animals on Earth

A new study reveals that oxygen levels during the “boring billion” period were only 0.1% of what they are today, providing the first evidence that oxygen levels were low enough during this period to potentially prevent the rise of animals. Geologists are letting the air out of a nagging mystery about the development of animal […]

New Calculations Show Pacific Plate Shrinking as it Cools

A newly published study from geophysicists Rice University and the University of Nevada challenge assumptions about a rigid lithosphere, revealing that the Pacific plate is shrinking as it cools. Houston – The tectonic plate that dominates the Pacific “Ring of Fire” is not as rigid as many scientists assume, according to researchers at Rice University […]

Scientists Detect Evidence of Water in Earths Mantle

New research reveals large quantities of water bound up in the rock located deep in the Earth’s mantle. Researchers have found evidence of a potential “ocean’s worth” of water deep beneath the United States. Although not present in a familiar form, the building blocks of water are bound up in rock located deep in the […]

New Evidence Raises Questions About When Dinosaurs Evolved in North America

Scientists at MIT precisely dated the rocks in which the earliest dinosaur fossils were discovered in the southwestern United States, raising questions about when dinosaurs evolved in North America. The Jurassic and Cretaceous periods were the golden age of dinosaurs, during which the prehistoric giants roamed the Earth for nearly 135 million years. Paleontologists have […]

Study Shows Gusev Crater on Mars Had a Lake

New research from Arizona State University shows evidence that the Gusev Crater on Mars once held a lake. If desert mirages occur on Mars, “Lake Gusev” belongs among them. This come-and-go body of ancient water has come and gone more than once, at least in the eyes of Mars scientists. Now, however, it’s finally shifting […]
