In movies, exploring the body up close often involves shrinking to microscopic sizes and taking harrowing rides through the blood. Thanks to a new virtual model, you can journey through a three-dimensional brain. No shrink ray required. The Society for Neuroscience and other organizations have long sponsored the website BrainFacts.org, which has basic information about […]

Smell has a reputation as a second-rate human sense. But that assumption stinks once hunter-gatherers enter the picture. Semaq Beri hunter-gatherers, who live in tropical forests on the eastern side of the Malay Peninsula in Southeast Asia, name various odors as easily as they name colors, say psycholinguist Asifa Majid and linguist Nicole Kruspe. Yet […]

Johnny Juzang was 10 years old when "Linsanity" became a phenomenon. For two magical months, Jeremy Lin showed Juzang and others that it was possible for an Asian American basketball player to succeed at the highest level. Eleven years later, Juzang occupies that same role for a new generation of players. Juzang may not be […]

A fossil jaw unearthed in Israel is speaking up about when humans departed Africa. The jaw’s message, at least to its finders: That ancient exodus started much earlier than many researchers had assumed. Misliya Cave on Israel’s Mount Carmel has yielded what its discoverers regard as a partial Homo sapiens jaw with an estimated age […]

Stone-tool makers in what’s now India redesigned their products in a revolutionary way much earlier than previously thought. Excavated stone artifacts document a gradual shift from larger, handheld cutting implements to smaller pieces of sharpened stone, known as Middle Paleolithic tools, by around 385,000 years ago, researchers say. That shift mirrors a similar change seen […]

A new type of laser is modeled after an exotic class of materials called topological insulators. And it’s proving more reliable and energy-efficient than its conventional counterparts, paving the way for possible use in quantum communication and next-generation electronics. The device, described online February 1 in Science, is composed of a grid of semiconductor rings […]

Newly fabricated superstrong lumber gives a whole new meaning to “hardwood.” This ultracompact wood, described in the Feb. 8 Nature, is created by boiling a wood block in a water-based solution of sodium hydroxide and sodium sulfite. The chemicals partially strip the wood of substances called lignin and hemicellulose, which help give wood its structure […]

For quantum computers, silicon’s springtime may finally have arrived. Silicon-based technology is a late bloomer in the quantum computing world, lagging behind other methods. Now for the first time, scientists have performed simple algorithms on a silicon-based quantum computer, physicist Lieven Vandersypen and colleagues report online February 14 in Nature. The computer has just two […]

AUSTIN, Texas — A new artificial organ gives a new meaning to the phrase “making eyes.” For the first time, researchers used human cells to build a model of the surface of the eye that’s equipped with a fake eyelid that mimics blinking. This synthetic eye could be used to study and test treatments for […]

Certain skin-dwelling microbes may be anticancer superheroes, reining in uncontrolled cell growth. This surprise discovery could one day lead to drugs that treat or maybe even prevent skin cancer. The bacteria’s secret weapon is a chemical compound that stops DNA formation in its tracks. Mice slathered with one strain of Staphylococcus epidermidis that makes the […]
