Adjusting pH levels in drinking water may be key to combating the obesity crisis

Obesity and health problems caused by high sugar content in drinks can be tackled by increasing the pH level and reducing the quantity of total dissolved solids (TDS) in water, according to research from the University of Sheffield, Innovate UK, De Montfort University and WET Global Ltd.

Digitizing and replicating the world of materials

Is it possible to digitally replicate the way light shines off silk, the kaleidoscope of colors on butterfly wings, or the structure of fabrics, plastics, and stones? A team of researchers at EPFL's Realistic Graphics Lab, headed by Wenzel Jakob, is developing computer models to do just that. Their process begins by meticulously digitizing any material they can lay their hands on, using a sophisticated machine called a gonio-photometer.

Sex differences in kidney injury

Evidence indicates men have higher incidence of chronic kidney disease and quicker renal decline than premenopausal women. However, sex differences in the expression and activation of the EGF receptor (EGFR), which mediates progressive renal injury, are largely unexplored.

Just how resilient are biofilms?

Biofilms hold promise for generating electricity and removing contamination from groundwater, but they also threaten many industrial processes and human health. As the environment changes in which these biofilms thrive, it is unclear how well these living systems will function. Earlier studies proved that certain biofilms were more resilient to changes in their environment, but how they survived was unclear. To help resolve the issue, researchers examined the molecular workings of model biofilms exposed to the toxic chemical, hexavalent chromium. Their work is helping understand biofilms' responses to stress.

Microfluidics: 2-D fingerprints of heterogenous proteins in solution

Microfluidic systems are used in molecular biology, biochemistry and biotechnology to rapidly analyze heterogenous biomolecular mixtures with high recovery rates and minute sample volumes. However, it is challenging to combine preparative and analytical processes within a single device for fast integrated analysis. In a recent study now published on Microsystems and Nanoengineering, Kadi L. Saar and co-workers at the interdisciplinary departments of chemistry, physics, and Fluidic Analytics Limited in Cambridge, U.K., have developed a chip combining the two steps of preparation and analysis.

Resilient shark spines may inform treatment for human bone disease

Sharks don't only have powerful jaws. They also have enviably strong spines. Their spines constantly flex when they swim, but never wear out during the fish's lifetime.

Could viruses affect climate? New study probes effects on global nutrient cycle

Nowadays we're getting more used to the idea that entire ecosystems of tiny bacteria are living on our skin, in the soil of our gardens and within the oceans where we catch dinner.

Scientists film rotating carbonyl sulphide molecules

Scientists have used precisely tuned pulses of laser light to film the ultrafast rotation of a molecule. The resulting "molecular movie" tracks one and a half revolutions of carbonyl sulphide (OCS)—a rod-shaped molecule consisting of one oxygen, one carbon and one sulphur atom—taking place within 125 trillionths of a second, at a high temporal and spatial resolution. The team headed by DESY's Jochen Küpper from the Center for Free-Electron Laser Science (CFEL) and Arnaud Rouzée from the Max Born Institute in Berlin are presenting their findings in the journal Nature Communications. CFEL is a cooperation of DESY, the Max Planck Society and Universität Hamburg.

NASA's Mars 2020 rover does biceps curls

The robotic arm on NASA's Mars 2020 rover does not have deltoids, triceps or biceps, but it can still curl heavy weights with the best. In this time-lapse video, taken July 19, 2019, in the clean room of the Spacecraft Assembly Facility at the Jet Propulsion Laboratory in Pasadena, California, the rover's 7-foot-long (2.1-meter-long) arm handily maneuvers 88 pounds' (40 kilograms') worth of sensor-laden turret as it moves from a deployed to a stowed configuration.

Radio galaxy 3C 236 investigated with LOFAR

Using the LOw Frequency ARray (LOFAR) astronomers took a closer look at the giant radio galaxy 3C 236. The observations, detailed in a paper published July 22 on the arXiv pre-print repository, shed more light on the morphology and structure of 3C 236, which could be helpful in advancing our knowledge about radio galaxies in general.

It pays to explore in times of uncertainty

When making choices, people tend either to go with what they know or try something new. We experience this trade-off every day, whether choosing a route to work or buying breakfast cereal. But does one strategy have an advantage over another? Researchers decided to examine this question by looking at fishing boat captains, who face this choice again and again when deciding where to fish.

Every transistor has a unique quantum fingerprint—but can it be used as a form of ID?

We might imagine that electric current flows as a smooth, even stream of electrons through our electronics devices, but at the quantum scale the flow of electric current might be more accurately pictured as a bubbling brook containing many tiny ripples. These ripples can be caused by single-electron effects, which arise due to the repulsion among electrons confined in very small spaces, such as trap sites in transistors. Single-electron effects can lead to tiny changes in the current-voltage characteristics of these devices.

Researchers develop novel imaging approach with potential to identify patients with CAD

Coronary artery disease (CAD) - caused by plaque buildup in the artery walls that constricts the flow of blood to the heart—is the most common form of heart disease and the leading cause of death for both men and women in the United States. Non-invasive imaging such as cardiovascular magnetic resonance imaging is often used to diagnose coronary heart disease. However, current techniques are cumbersome, costly and expose patients to adverse health risks.

Most deaths related to noncardiac surgery occur after surgery and after discharge from hospital

It's not the operating room that is risky for patients undergoing noncardiac surgery; it's the recovery period. According to a large international study, only 0.7% of deaths in these patients occurred in the operating room, whereas 29% of deaths occurred after discharge from hospital. The study, which included patients at 28 centres in 14 countries, was published in CMAJ (Canadian Medical Association Journal).
