New MRI sensor can image activity deep within the brain
Noninvasive measurements of calcium could reveal neurons' roles in different types of behavior. Calcium is a critical signaling molecule for most cells, and it is especially important in neurons. Imaging calcium in brain cells can reveal how neurons communicate with each other; however, current imaging techniques can only penetrate a few millimeters into the brain.

Physicists calculate proton’s pressure distribution for first time
The particle's core withstands pressures higher than those inside a neutron star, according to a new study. Neutron stars are among the densest-known objects in the universe, withstanding pressures so great that one teaspoon of a star's material would equal about 15 times the weight of the moon. Yet as it turns out, protons - the fundamental particles that make up most of the visible matter in the universe - contain even higher pressures.

Quantum dots can spit out clone-like photons
System that generates coherent single particles of light could help pave the way for quantum information processors or communications. In the global quest to develop practical computing and communications devices based on the principles of quantum physics, one potentially useful component has proved elusive: a source of individual particles of light with perfectly constant, predictable, and steady characteristics.

How to Freeze Heat Conduction
Physicists have discovered a new effect, which makes it possible to create excellent thermal insulators which conduct electricity. Such materials can be used to convert waste heat into electrical energy. Every day we lose valuable energy in the form of waste heat - in technical devices at home, but also in large energy systems.

ANU at the forefront of ground-breaking solar research
Scientists at The Australian National University (ANU) have made a fresh series of breakthroughs that could help further revolutionise solar technology - making it more efficient, and more accessible - following major discoveries last year. The team from ANU have been concentrating on the solar cell's skin layer, which is 1,000 times thinner than a human hair, and is used to conduct electricity and protect the solar cell.

Of quark speeds finds a solution for a 35-year physics mystery
Number of proton-neutron pairs determine how fast the particles move, results suggest. MIT physicists now have an answer to a question in nuclear physics that has puzzled scientists for three decades: Why do quarks move more slowly inside larger atoms? Quarks, along with gluons, are the fundamental building blocks of the universe.

Dietary Fiber Helps Clump Material in Your Gut
Food, microbes, and medicine all clump together as they move through our gut. Sticky molecules secreted into our intestines bind the gut particles in the same way that flour holds a ball of dough together. Now a new mice-based study from Caltech is showing that dietary fiber also plays a role in clumping.

Superconduction: Why does it have to be so cold?
Currently, there is no precise computation method to describe superconducting materials. TU Wien has now made a major advance towards achieving this goal and, at the same time, has furthered an understanding of why conventional materials only become superconducting at around -200°C Why does it always have to be so cold? We now know of a whole range of materials that ' under certain conditions ' conduct electrical current entirely without resistance.

Earth’s atmosphere stretches out to the Moon - and beyond
The outermost part of our planet's atmosphere extends well beyond the lunar orbit - almost twice the distance to the Moon. A recent discovery based on observations by the ESA/NASA Solar and Heliospheric Observatory, SOHO, shows that the gaseous layer that wraps around Earth reaches up to 630 000 km away, or 50 times the diameter of our planet.

Giving keener "electric eyesight" to autonomous vehicles
On-chip system that detects signals at sub-terahertz wavelengths could help steer driverless cars through fog and dust. Autonomous vehicles relying on light-based image sensors often struggle to see through blinding conditions, such as fog. But MIT researchers have developed a sub-terahertz-radiation receiving system that could help steer driverless cars when traditional methods fail.

Cosmic dust forms in supernovae blasts
Scientists claim to have solved a longstanding mystery as to how cosmic dust, the building blocks of stars and planets, forms across the Universe. Cosmic dust contains tiny fragments or organic material and is spread out across the Universe. The dust is primarily formed in stars and is then blown off in a slow wind or a massive star explosion.
