Gravitational Waves Found, Black-Hole Models Led the Way

GWvisual.jpg

Gravitational waves were predicted by Einstein’s theory of general relativity in 1916, and now, almost exactly 100 years later, the faint ripples across space-time have been found. The advanced Laser Interferometric Gravitational-wave Observatory (aLIGO) has achieved the first direct measurement.

Gravitational Waves Detected 100 Years After Einstein’s Prediction

For the first time, scientists have observed ripples in the fabric of spacetime called gravitational waves, arriving at the Earth from a cataclysmic event in the distant universe. A UAH researcher was at the center of action.

LIGO Announces the Detection of Gravitational Waves - Experts Needed

ScreenShot2016-02-11at10.50.12AM.png

Scientist using LIGO have observed the warping of space-time generated by the collision of two black holes more than a billion light-years from Earth. This is the first direct detection of gravitational waves, first proposed by Albert Einstein in his Theory of General Relativity, published in 1916.

The Big Science Comes From UW-Milwaukee’s Big Data

The detection of gravitational waves came after a nearly 20-year search – the largest and most ambitious project ever funded by the National Science Foundation – and physicists at the University of Wisconsin-Milwaukee played an essential role in both computing and data analysis.

Bumpy Liquid Films Could Simplify Fabrication of Microlenses

APL-Nejati-liquidfilm.jpg

Have you ever noticed that when heated a film of oil in a pan doesn’t remain completely flat? Instead, it forms a wavy pattern that resembles the exterior of an orange. These sorts of deformations inspired a group of researchers at the Technical University of Darmstadt, in Germany, to explore whether they could be used to improve and streamline microfabrication processes.

Physics Plays Key Role in How White Blood Cells Fight Infection

microfluidic_device_prop.jpg

Researchers at Georgia Tech and Emory fabricated model blood vessel systems that include artificial blood vessels with diameters as narrow as the smallest capillaries in the body. The systems were used to study the activity of white blood cells as they were affected by drugs that tend to make them softer, which facilitates their entry into blood circulation.

SLAC X-Ray Laser Turns Crystal Imperfections Into Better Images of Important Biomolecules

infinite_ducks.jpg

Often the most difficult step in taking atomic-resolution images of biological molecules is getting them to form high-quality crystals needed for X-ray studies of their structure. Now researchers have shown they can get sharp images even with imperfect crystals using the world’s brightest X-ray source at the Department of Energy’s SLAC National Accelerator Laboratory.

Body Temperature Triggers Newly-Developed Polymer to Change Shape

BodyTempSMP.jpg

Polymers that visibly change shape when exposed to temperature changes are nothing new. But a research team led by Chemical Engineering Professor Mitch Anthamatten at the University of Rochester created a material that undergoes a shape change that can be triggered by body heat alone, opening the door for new medical and other applications.

Using a model blood vessel system built on a polymer microchip, researchers have shown that the relative softness of white blood cells determines whether they remain in a dormant state along vessel walls or enter blood circulation to fight infection.

Chiral Magnetic Effect Generates Quantum Current

D1600116copy.jpg

Scientists at the U.S Department of Energy's (DOE) Brookhaven National Laboratory and Stony Brook University have discovered a new way to generate very low-resistance electric current in a new class of materials. The discovery, which relies on the separation of right- and left-"handed" particles, points to a range of potential applications in energy, quantum computing, and medical imaging, and possibly even a new mechanism for inducing superconductivity--the ability of some materials to carry current with no energy loss.
