Talking to ourselves and voices in our heads
As far our brain is concerned, talking to ourselves in our heads may be fundamentally the same as speaking our thoughts out loud, new research shows. The findings may have important implications for understanding why people with mental illnesses such as schizophrenia hear voices.

Three kinds of information from a single X-ray measurement
The way in which electronic devices operate relies on the interaction between various materials. For this reason, researchers need to know exactly how specific chemical elements inside a computer chip or a transistor diode behave, and what happens when these elements bond. Physicists have now developed an innovative method that enables them to obtain several different types of information simultaneously from the interior of a nanoscale building block, and this while it is in the active state.

Sandy claws: Like holiday enthusiasts, majoid crabs decorate their shells
Majoid crabs -- known as decorator crabs -- adorn themselves with items secured from their surroundings such as sponges, algae and other marine debris. Scientists are exploring what factors drive this behavior.

Physicists excited by discovery of new form of matter, excitonium
Excitonium has a team of researchers ... well... excited! They have demonstrated the existence of an enigmatic new form of matter, which has perplexed scientists since it was first theorized almost 50 years ago.

Blackbody radiation from a warm object attracts polarizable objects
You might think that a hot object pushes atoms and molecules away due to radiation pressure. But a research team showed that for a polarizable atom, the opposite occurs: the hot object attracts it. Using an atom interferometer, they found the attraction was 20 times stronger than the gravitational attraction between a tungsten object and a cesium atom. Though negligible in most situations, next-generation gravitational wave experiments may have to take this into account.

Taurine lends hand to repair cells damaged in multiple sclerosis
New research suggests that administering taurine, a molecule naturally produced by human cells, could boost the effectiveness of current multiple sclerosis (MS) therapies.

Extreme fieldwork, climate modeling yields new insight into predicting Greenland's melt
A new study brings together scientists from land hydrology, glaciology and climate modeling to unravel a meltwater mystery. Researchers discovered that some meltwater from the lakes and rivers atop the region's glaciers, is being stored and trapped on top of the glacier inside a low-density, porous 'rotten ice.' This phenomenon affects climate model predictions of Greenland's meltwater.

Boosting the antibiotic arsenal
A NEW way to make bacteria more vulnerable to a class of antibiotics known as quinolones, which include ciprofloxacin and are often used to treat infections such as Escherichia coli and Staphylococcus aureus, has been discovered by researchers.

Scientists slow progression of fatal form of muscular dystrophy
Researchers report that a new drug reduces fibrosis (scarring) and prevents loss of muscle function in an animal model of Duchenne muscular dystrophy (DMD).
