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.

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.

Researchers have developed a way to find hypoxic spots noninvasively in real time. The researchers developed an oxygen-sensitive molecular beacon that emits ultrasound signals in response to light, a process called photoacoustic imaging.

Different low carbon technologies from wind or solar energy to fossil carbon capture and sequestration (CCS) differ greatly when it comes to indirect GHG emissions in their life cycle. The new study finds that wind and solar energy belong to the more favorable when it comes to life-cycle emissions and scaling up these technologies would induce only modest indirect GHG emissions -- and hence not impede the transformation towards a climate-friendly power system.

Going undercover to fight tuberculosis
Tuberculosis is one of the most widespread life-threatening infectious diseases.

In search of new antibiotics, researchers have developed a structural analogue of mycolic acid, the essential membrane building block. This drug blocks key enzymes used in mycomembrane biosynthesis, significantly increasing the effectiveness of conventional antibiotics.

Unique pattern of brain inflammation may explain neurocognitive impairment in HIV patients on antiretroviral drugs
Almost half of combination antiretroviral therapy (cART)-treated HIV patients experience some degree of neurocognitive impairment (neuroHIV). To search for underlying pathology, scientists analyzed the brains of monkeys infected with simian immunodeficiency virus (SIV) then treated with cART. The majority of the SIV-infected macaque brains showed signs of unusual lymphocyte-dominant inflammation, suggesting that persistent neuroinflammation may underlie cognitive problems in cART-treated HIV patients.

Life of an albatross: Tackling individuality in studies of populations
Ecologists commonly round off the individuality of individuals, treating animals of the same species, sex, and age like identical units. But individual differences can have demographic effects on interpretation of data at the scale of whole populations, if due to an underlying variability in individual quality, not chance. Researchers examined in the peculiarities that make some wandering albatrosses more successful than others.

Money-saving health plans do little to curb spending on unnecessary medical services
Claims for unnecessary medical services remain steady, despite changes in the insurance market designed to place more spending decisions in consumers' hands, report investigators. An increasingly common type of high-deductible insurance plan is touted for its money-saving potential, but a growing body of research indicates the plans don't motivate patients - or doctors - to curb spending on unnecessary medical services.
