New Computer Neural Networks Can Visually Identify as Well as the Primate Brain

A new study from MIT neuroscientists shows that the newest computer neural networks can identify visual objects as well as the primate brain. For decades, neuroscientists have been trying to design computer networks that can mimic visual skills such as recognizing objects, which the human brain does very accurately and quickly. Until now, no computer […]

Study Shows Computer Games Can Change the Behavior of Psychopaths

New research from Yale University shows that computer games can be used to change the behavior of psychopaths, teaching them to consider emotion and other pieces of information when they make decisions. Psychopaths generally do not feel fear and fail to consider the emotions of others, or reflect upon their behavior — traits that make […]

Aquilops Americanus Oldest Horned North American Dinosaur

A team of paleontologists has discovered the oldest known “horned” dinosaur fossil from North America. Named Aquilops americanus, the species is 40 million years older than the iconic Triceratops. A fossil skull small enough to fit in the palm of your hand represents the oldest species of horned dinosaur named from North America. The discovery, […]

Neuroscientists Reveal Fundamental Discovery about Cortical Neurons

Neuroscientists from the Picower Institute for Learning and Memory uncover a fundamental discovery about cortical neurons, showing that inhibitory neuron functionality is not an immutable property of cortical cells, but a consequence of more complex network dynamics. The two major types of neuron in the brain’s cerebral cortex are connected by intricate cortical circuits that […]

Men and Women Respond Differently to Cigarettes

New research from Yale University shows that men and women respond to cigarettes differently, demonstrating for the first time that smoking-induced dopamine activation occurs in a different brain region and much faster in nicotine-dependent men than women. Yale researchers using a new brain imaging analysis method have confirmed that smoking cigarettes activates a dopamine-driven pleasure […]

Dopamine Precursor in Toxic Fruits Increases Fertility

In a new study, researchers from the Max Planck Institute reveal that a dopamine precursor in the toxic fruits of the morinda tree increases fertility in female Drosophila sechellia flies. In the course of evolution, animals have become adapted to certain food sources, sometimes even to plants or to fruits that are actually toxic. The […]

MIT Engineers Design Complex DNA Shapes

Biological engineers from MIT have developed a new computer model that enables them to design the most complicated 3D structures ever made from DNA, including rings, bowls, and geometric structures such as icosahedrons that resemble viral particles. This design program could allow researchers to build DNA scaffolds to anchor arrays of proteins and light-sensitive molecules […]

Monkeys Aren’t Fooled by Expensive Brands

A newly published study from Yale University shows that although Capuchin monkeys exhibit a number of irrational behaviors similar to humans, the monkeys aren’t fooled by expensive brands. In at least one respect, Capuchin monkeys are smarter than humans — they don’t assume a higher price tag means better quality, according to a new Yale […]

Research Shows Sunlight Produces the Color of Jupiter's Great Red Spot

Using a combination of data from Cassini’s December 2000 Jupiter flyby and laboratory experiments, new research suggests effects of sunlight produce the color of Jupiter’s Great Red Spot. The ruddy color of Jupiter’s Great Red Spot is likely a product of simple chemicals being broken apart by sunlight in the planet’s upper atmosphere, according to […]

Microbullets Confirm the Strength of Graphene

A newly published study from Rice University shows that graphene is 10 times better than steel at absorbing the energy of a penetrating projectile. Graphene’s great strength appears to be determined by how well it stretches before it breaks, according to Rice University scientists who tested the material’s properties by peppering it with microbullets. The […]

Deep Sea Shrimp May Hold Clues to Alien Life

Scientists at NASA’s Jet Propulsion Laboratory reveal that the extreme oasis of life deep in the Caribbean Sea may hold clues to life on other planetary bodies, including Jupiter’s moon Europa. At one of the world’s deepest undersea hydrothermal vents, tiny shrimp are piled on top of each other, layer upon layer, crawling on rock […]

Researchers Control a Material with Voltage

New research details how a MIT-based team has made important strides in the concept of using an electrical signal to control a magnetic memory. A new way of switching the magnetic properties of a material using just a small applied voltage, developed by researchers at MIT and collaborators elsewhere, could signal the beginning of a […]

Calorie-Restricting Diets Slow Aging

Neuroscientists show that calorie-reduced diets stop the normal rise and fall in activity levels of close to 900 different genes linked to aging and memory formation in mice. The adage ‘you are what you eat’ has been around for years. Now, important new research provides another reason to be careful with your calories. In a […]

Researchers Develop Nano Devices That Can be Propelled Through Media Similar to Bodily Fluids

Scientists from the Max Planck Institute have constructed swimming bodies that are small enough to be used in bodily fluids or even individual cells, and they are able to navigate through complex biological fluids. In the 1966 movie Fantastic Voyage, a submarine complete with crew is shrunk in size so that it can navigate through […]
