Starting age of marijuana use may have long-term effects on brain development

The age at which an adolescent begins using marijuana may affect typical brain development, according to researchers. Scientists describe how marijuana use, and the age at which use is initiated, may adversely alter brain structures that underlie higher order thinking.

Prelinguistic infants can categorize colors

Researchers have revealed that infants aged between 5 and 7 months hold the representation of color categories in their brain, even before the acquisition of language.

A star's moment in the spotlight

A newly formed star lights up the surrounding clouds in this new image from ESO's La Silla Observatory in Chile. Dust particles in the vast clouds that surround the star HD 97300 diffuse its light, like a car headlight in enveloping fog, and create the reflection nebula IC 2631. Show More Summary

Liveblog: Scientists to announce major gravitational wave finding

Ars goes to the source of gravitational wave science, a large detector in Louisiana.

Epilepsy at the molecular level

Researchers study the link between malformations of the cerebral cortex and the occurrence of the neurological disease. Why does a structural irregularity in the temporal lobe make humans more susceptible to epileptic seizures? Experts have been searching for the answer to this question for a long time.

SLAC X-ray laser turns crystal imperfections into better images of important biomolecules

Menlo Park, Calif. -- Often the most difficult step in taking atomic-resolution images of biological molecules is getting them to form high-quality crystals needed for X-ray studies of their structure. Now researchers have shown they...Show More Summary

Individuals experiencing anger, contempt and disgust are more likely to act and behave in a hostile manner toward those they disagree with, new research from San Francisco State University shows. Past research had demonstrated an association...Show More Summary

Plankton carries carbon to safe resting spot, ocean study reveals

COLUMBUS - The ocean's power to rein in carbon and protect the environment is vast but not well-understood. But now, an international team of scientists has begun to illuminate how the ocean plucks carbon from the atmosphere, where it...Show More Summary

Radical CO2 removal projects could be a risky business

Radical new ways of removing CO2 from the atmosphere could prove to be a risky business -- according to an environmental scientist at the University of East Anglia. Techniques put forward include growing crops to be burned in power stations,...Show More Summary

New hope in global race to beat malaria parasite's deadly new resistance

Scientists have made a major breakthrough in the global search for a new drug to beat the malaria parasite's growing resistance to first-defence treatments. The deadly mosquito-borne malaria parasite kills around 450,000 children every year. Show More Summary

A new method furthers understanding of evolutionary genetics

Since Darwin, evolutionary biologists have been fascinated by how different organisms are from one another. The ultimate goal is to understand how mutations in DNA, the genetic blueprint, shape the growth and behavior of animals, plants, and microbes around us. Show More Summary

UBC-led study finds beliefs about all-knowing gods fosters co-operation

Beliefs about all-knowing, punishing gods -- a defining feature of religions ranging from Christianity to Hinduism -- may have played a key role in expanding co-operation among far-flung peoples and led to the development of modern-day states, according to a UBC-led study published in Nature. read more

Study challenges widely accepted theory of Yellowstone formation

CHAMPAIGN, Ill. -- Understanding the complex geological processes that form supervolcanoes could ultimately help geologists determine what triggers their eruptions. A new study using an advanced computer model casts doubt on previously held theories about the Yellowstone supervolcano's origins, adding to the mystery of Yellowstone's formation. read more

Oops! Giant Raptor’s Wishbone is Actually a Bit of Turtle Shell

Last November, palaeontologists announced the discovery of Dakotaraptor, a super-sized relative of Velociraptor that stalked the Hell Creek Formation of North America alongside Tyrannosaurus rex. It was a formidable animal, 18 feet in length, with 9.5-inch sickle-shaped claws on its feet. The dramatic beast was described by Robert DePalma from the Palm Beach Museum of […]

Scientists write document explaining Zika Virus, urge vigilance

Public concerns about Zika have triggered scientists to write a new Extension document to explain the virus. Meanwhile, state mosquito control agencies and the Florida Department of Health monitor local areas for diseases and for these mosquito species.

New study reveals visual working memory may provide clues to autism's social struggles

Poor visual working memory can play an important role in the struggles experienced by autistic children, according to a new study. The aim of this study was to compare the working memory profiles of autistic children with typically developing children. The results suggest that children with autism have much worse visual working memory compared to typically developing students.

Spin waves out of waste heat: Researchers present new findings on magnetic spin waves

Principles of the conversion from heat currents to magnonic spin currents have been discovered by researchers. Spin waves, or magnons, are fundamental excitations in magnetic materials which transport energy and angular momentum. The latter allows to make use of them for the transmission of information within magnetic solids.
