Rare tooth find reveals horned dinosaurs in eastern North America

A chance discovery in Mississippi provides the first evidence of an animal closely related to Triceratops in eastern North America. The fossil, a tooth from rocks between 68 and 66 million years old, shows that two halves of the continent previously thought to be separated by seaway were probably connected before the end of the Age of Dinosaurs.

Spacewalking astronauts tackle urgent station repairs

Spacewalking astronauts are making urgent repairs at the International Space Station.

How do we know the millennial generation exists? Look at the data

Cultures change, and new generations are born out of those changes. For many, this might sound obvious.

Making biological drugs with spider silk protein

Researchers at Karolinska Institutet in Sweden have managed to synthesise lung surfactant, a drug used in the care of preterm babies, by mimicking the production of spider silk. Animal studies reveal it to be just as effective as the biological drugs currently in clinical use. The study is published in Nature Communications.

Homonyms

Yesterday’s Dumbing of Age: In fact Walky is right about homonym. The OED’s overall gloss is “The same name or word used to denote different things”, with the more specific sense “Philol. Applied to words having the same sound, but differing in meaning”. Billie is right about the etymology — for the verb funk “To blow smoke upon […]

Large study uncovers genes linked to intelligence

Exactly what constitutes intelligence, and to what extent it is genetic, are some of the most controversial questions in science. But now a new study of nearly 80,000 people, published in Nature Genetics, has managed to identify a number of genes that seem to be involved in intelligence.

Homo naledi genome: Will we ever find this elusive key to human evolution? | Jennifer Raff

Despite the recent announcement of a new haul of Homo naledi fossils, recovering ancient DNA is still proving as difficult as ever Despite what many people believe, paradigm-shifting moments in science - where our understanding of a particular explanation is challenged by a single finding - are actually quite rare.

Researchers find first compelling evidence of new property known as 'ferroelasticity' in perovskites

Crystalline materials known as perovskites could become the next superstars of solar cells. Over the past few years, researchers have demonstrated that a special class of perovskites—those consisting of a hybrid of organic and inorganic...Show More Summary

Did humans evolve in Europe rather than Africa? We don't have the answer just yet

Charles Darwin believed that humans evolved in Africa, because that's where our closest ape relatives the chimpanzees and gorillas live. And during the twentieth century he was vindicated through a combination of fossil and genetic discoveries.

Dietician addresses lack of healthy vegetable education in intermediate schools

A Massey University dietitian is concerned at the lack of skills taught to intermediate school children about creating and cooking simple meals using vegetables.

This is what Asian Americans really think about undocumented immigration

Are legal immigrants opposed to undocumented immigration? Recently, a group of first-generation Chinese Americans have made the national news by showing up at hearings and objecting vociferously to sanctuary city policies, which aim to protect people who are in the United States without documents. News articles covering this group suggest that there may be a […]

Zombies in Sci-Fi Novel Have Gruesome Real-World Inspiration

Unlike most of the zombie plagues that populate sci-fi movies and novels, the infectious agent in "The Boy on the Bridge" is grounded in horrific reality.

Corn seed treatment insecticides pose risks to honey bees, yield benefits elusive

Nearly every foraging honey bee in the state of Indiana will encounter neonicotinoids during corn planting season, and the common seed treatments produced no improvement in crop yield, according to a Purdue University study.

Why Bad Moods Are Good For You

Bad moods and sadness are a normal, and even a useful and adaptive part of being human, helping us cope with many everyday situations and challenges.

Italy's Supervolcano Builds Up Stress — But No Eruption Coming

A large caldera called Campi Flegrei in Naples may be more stressed than previously thought.

Attempt to Smuggle Coins from Turkey to Russia Foiled

Syrian caught at ?anl?urfa airport boarding a plane to Istanbul on his way to Russia with Roman and Hellenistic coins (article in Turkish) Now find a dealer that would have had any qualms once they reached the international market at about buying and then selling on those coins without any paperwork at all showing how they came onto the market.

Report sheds new insights on the spin dynamics of a material candidate for low-power devices

Computers process and transfer data through electrical currents passing through tiny circuits and wires. As these currents meet with resistance, they create heat that can undermine the efficiency and even the safety of these devices...

Image: Slim crescent of Enceladus

The low angle of sunlight along the slim crescent of Saturn's moon Enceladus (313 miles or 504 kilometers across) highlights the many fractures and furrows on its icy surface.

Research reveals insights into optical properties of plasmonic nanostructures

University of Arkansas researchers have helped define the optical properties of plasmonic nanostructures, work that could lead to improved sensors in security and biomedical devices, and have applications in solar cells. The research team in the Department of Physics recently published its findings in the journal PLOS ONE.

Weyl fermions exhibit paradoxical behavior

Theoretical physicists have found Weyl fermions to exhibit paradoxical behavior in contradiction to a 30-year-old fundamental theory of electromagnetism. The discovery has possible applications in spintronics. The study has been published in Physical Review Letters.
