New portable blood analyzer could improve anemia detection worldwide

About one quarter of the world's population suffers from anemia, a disease caused by a concentration deficiency of hemoglobin in red blood cells. To reduce the burden of anemia, health officials need a better picture of the disease's global impact, an understanding made viable by a portable and affordable way to analyze blood.

Researchers identify free-flowing aerosol particles using holograms, lasers

Holographic images of free-flowing air particles may help climate change and biological weapons watchdogs better monitor the atmosphere, according to a recent Kansas State University study.

Free-flowing aerosol particles identified using holograms, lasers

Holographic images of free-flowing air particles may help climate change and biological weapons watchdogs better monitor the atmosphere, according to a recent study. The images are made by two overlapping lasers that could be mounted on an unmanned aircraft to monitor the atmosphere.

Computational study sheds doubt on latest theory of birds' mysterious magnetic compass

The European robin and other birds know where to migrate by sensing the direction of the Earth's magnetic field. Researchers have recently attributed this ability to a chemical reaction that takes place within the eye and whose success depends on the field direction.

Breaking the rules: Heavy chemical elements alter theory of quantum mechanics

The theory of quantum mechanics does not adequately explain how the heaviest and rarest elements found at the end of the table function, say scientists. Instead, another well-known scientific theory -- Albert Einstein's famous Theory of Relativity -- helps govern the behavior of the last 21 elements of the Periodic Table.

Nobel Prize in Physics 2017: Gravitational waves

The Nobel Prize in Physics 2017 goes to Rainer Weiss, Barry C. Barish, and Kip S. Thorne "for decisive contributions to the LIGO detector and the observation of gravitational waves."

Scientists pinpoint the singularity for quantum computers

Super-powerful quantum computers, which scientists and engineers across the world are racing to build, need to be even more powerful than previously thought before they can beat today's ordinary PCs, researchers have discovered.

Ultra-energy-efficient magnetic memory by controlling the shapes of atoms

A research group led by Osaka University discovered a new principle to realize ultra-energy-efficient magnetic memory by electrically controlling the shapes of atoms.

Random movements help color-detecting cells form the proper pattern

In fish and other animals, the color detecting cone cells in the retina are arranged in specific patterns, and this is believed to be important for allowing animals to properly sense their surroundings. Now, in research published in Physical Review E, an interdisciplinary group of physicists and biologists have used a mathematical model to determine how the cone cells in zebrafish—a common experimental fish model—are arranged in a specific pattern in all individuals.

Gravitational wave detectors could shed light on dark matter

A global team of scientists, including two University of Mississippi physicists, has found that the same instruments used in the historic discovery of gravitational waves caused by colliding black holes could help unlock the secrets of dark matter, a mysterious and as-yet-unobserved component of the universe.
