Oxygen atoms in 15‑million‑year‑old giant eggshells reveal how plants reacted to a hotter
Some periods in Earth's history are so different from our own that they may as well belong to another planet. Many people are interested in the age of dinosaurs or the Ice Ages, but it is an intermediate world, the Miocene Epoch—a sort of "in-between" world, geologically speaking
The sun's outbursts may briefly weaken rain and snow events across North America
For decades, scientists have searched for a clear link between the sun's explosive storms and the weather that occurs on Earth. A breakthrough study from the University of New Hampshire reveals that in the hours and days following a solar storm, parts of North America can see sha
Scientists uncover evolutionary edge behind plant invasions
Plants that become invasive may owe their success to an advantage shaped long before they arrive, according to new research led by King's College London.
Lost megalodon vertebrae resurface, confirming 80-foot size estimate
An associated set of gigantic vertebrae belonging to the iconic extinct megalodon, or megatooth shark, that had been missing in action since the 1980s was discovered, providing new information about the shark's lifestyle. Two Museum of Southern Jutland staff members, Mette Elstru
Brain activity under anesthesia challenges what we know about consciousness
The unconscious brain appears to be far more capable than scientists once believed. Researchers found that patients under general anesthesia could still process language at a sophisticated level, distinguishing nouns, verbs, and adjectives while listening to stories. Even more re
Tiny DNA 'hitchhikers' may be reshaping life in thawing Arctic soils
Amid the peatlands of northern Sweden, billions of microbes are quietly rewriting their genetic playbooks—and doing so far more often than scientists realized.
Why people worldwide see some mental abilities as inborn and others as learned
When does a child begin to reason? When do they develop self-control? Are some mental abilities present from birth, while others are acquired through experience? Questions like these have fascinated philosophers, educators and scientists for centuries. Yet surprisingly little is
Structural blueprint for RNA therapeutics reveals why some siRNA molecules work better tha
RNA interference is a natural mechanism for living cells to control whether specific genes are being used. Crowned with the 2006 Nobel Prize in Physiology or Medicine, the discovery of RNA interference has since been harnessed by scientists to create a powerful and growing class
Deep-sea extremophile yields protein that forms super stable biofilm
Scientists discovered a protein secreted by a deep-sea extremophile—an organism adapted to extreme environmental conditions—that self-assembles into a biofilm and is highly stable, boosting its potential for biomedical applications.
Plutonium compound unlocks rare topological quantum behavior with potential nuclear scienc
Plutonium is one of the most complex elements in the periodic table. First synthesized and isolated in 1940 by scientists at the University of California, Berkeley, plutonium has been studied closely for more than eight decades. It's most often associated with its role in nuclear
Cochlea network model reveals how inner ear may sort sound from noise
Over 70 million people in the U.S. are impacted by hearing loss, and age-related hearing loss is the second most common health problem in older adults, according to the Advanced Research Projects Agency for Health. However, scientists still do not fully understand how the cochlea
