Brain uses both neural 'teacher' and 'tinkerer' in learning
While most people need peace and quiet to cram for a test, the brain itself may need noise to learn, a recent MIT study suggests. In experiments with monkeys, the researchers found that neural activities in the brain gradually change, even when nothing new is being learned. Challenging the monkeys to adjust their task triggered systematic changes in their neural activities on top of this background "noise."
Researchers at UCLA develop new nanomaterials to deliver anticancer drugs to kill cancer cells
Researchers at UCLA have successfully manipulated nanomaterials to create a new drug-delivery system that promises to solve the challenge of the poor water solubility of today's most promising anticancer drugs and thereby increase their effectiveness.
Math that powers spam filters used to understand how brain learns to move our muscles
A team of biomedical engineers has developed a computer model that makes use of more or less predictable "guesstimates" of human muscle movements to explain how the brain draws on both what it recently learned and what it's known for some time to anticipate what it needs to develop new motor skills.
Fingerprints reveal lifestyle habits
Scientists at the University of East Anglia have shown how a new forensic technique for fingerprints could be used to reveal a person's lifestyle habits.
Forgetting helps you remember the important stuff
For the first time, Stanford researchers using functional magnetic resonance imaging (fMRI) have discovered that the brain's ability to suppress irrelevant memories makes it easier for humans to remember what's really important.
Cancer drug enhances long-term memory
A drug used to treat cancer has been shown to enhance long-term memory and strengthen neural connections in the brain, according to a new study by UC Irvine scientists.
Music to deaf ears
More than three decades ago, scientists pursued the then-radical idea of implanting tiny electronic hearing devices in the inner ear to help profoundly deaf people. An even bolder alternative that promised superior results — implanting a device directly in the auditory nerve — was set aside as too difficult, given the technology of the day.
Fermilab physicists discover triple-scoop baryon
It was already known that people respond faster when prepared. However Dutch researcher Jan-Mathijs Schoffelen has now unravelled the mechanism in the brain behind this phenomenon. Transmitting and receiving neurons synchronise with each other so that the stimulus is transmitted more efficiently.

Dietary calcium is better than supplements at protecting bone health
Women who get most of their daily calcium from food have healthier bones than women whose calcium comes mainly from supplemental tablets, say researchers at Washington University School of Medicine in St. Louis. Surprisingly, this is true even though the supplement takers have higher average calcium intake.

New findings challenge established views on human genome
An international research consortium published a set of papers that promise to reshape our understanding of how the human genome functions. The findings challenge the traditional view of our genetic blueprint as a tidy collection of independent genes, pointing instead to a complex network in which genes, along with regulatory elements and other types of DNA sequences that do not code for proteins, interact in overlapping ways not yet fully understood.
Scientists solve genome of marine organism producing promising disease-fighting agents
It was already known that people respond faster when prepared. However Dutch researcher Jan-Mathijs Schoffelen has now unravelled the mechanism in the brain behind this phenomenon. Transmitting and receiving neurons synchronise with each other so that the stimulus is transmitted more efficiently.
Have I been here before?
"Have I been here before?" In today's fast-moving world of look-alike hotel rooms and comparable corridors, it can take a bit of thinking to answer this simple question. University of Bristol neuroscientists working with colleagues at the Massachusetts Institute of Technology (MIT) report in the June 7 early online edition of Science that they have identified a neuronal mechanism that our brains may use to rapidly distinguish similar, yet distinct places.
Calorie density key to losing weight
Eating smart, not eating less, may be the key to losing weight. A year-long clinical trial by Penn State researchers shows that diets focusing on foods that are low in calorie density can promote healthy weight loss while helping people to control hunger.
Now, self-healing materials can mimic human skin, healing again and again
The next generation of self-healing materials, invented by researchers at the University of Illinois, mimics human skin by healing itself time after time. The new materials rely upon embedded, three-dimensional microvascular networks that emulate biological circulatory systems.
To keep fit in space, train like an athlete
If one part of your car isn't properly maintained, it can affect how the entire vehicle runs – especially if you're taking a long trip. The same can be said for the human body. That's why, when it comes to fitness in space, it's important to create a program addressing the whole system, parts included.
Brain's inertial navigation system pinpointed
Researchers have discovered a sophisticated neural computer, buried deep in the cerebellum, that performs inertial navigation calculations to figure out a person's movement through space.
Zeroing in on the brain's speech 'receiver'
A particular resonance pattern in the brain's auditory processing region appears to be key to its ability to discriminate speech, researchers have found. They found that the inherent rhythm of neural activity called "theta band" specifically reacts to spoken sentences by changing its phase. The researchers also noted that the natural oscillation of this frequency provides further evidence that the brain samples speech segments about the length of a syllable.
Blind people are 'serial memory' whizzes
Compared to people with normal vision, those who were blind at birth tend to have excellent memories. Now, a new study reported online on June 21st in the journal Current Biology, a publication of Cell Press, shows that blind individuals are particular whizzes when it comes to remembering things in the right order.
Brain's voluntary chain-of-command ruled by not one but two captains
A probe of the upper echelons of the human brain's chain-of-command has found strong evidence that there are not one but two complementary commanders in charge of the brain, according to neuroscientists at Washington University School of Medicine in St. Louis.
