A gold catalyst whose behavior can be controlled by the addition of acid or metal ion cofactors has been designed by chemists. They have developed a catalyst with significantly enhanced properties based on a rotaxane, in which a gold catalyst is embedded in the cavity formed by threading a ring shaped molecule around a dumbell shaped axle. On its own , the rotaxane gold catalyst is unreactive but the addition of ions that bind into a pocket in the catalyst framework leads to rapid reactions.

When it comes to recording accurate performance data for elite athletes, GPS technology can't keep up, a researcher claims. Instead researchers have developed SABEL Sense, an alternative to GPS for tracking running speeds and distances and which is set to be a game changer in the sports performance and wearable technology industries.

Asimple approach to synthesize novel environmentally friendly manganese dioxide ink by using glucose has been developed by a group of scientists.

College professors and instructors can learn a lot from the chapters of a digital textbook that they assign students to read. According to a study, digital books provide real-time analytics to help faculty assess how students are doing in the class.

A new article offers horse owners advice on how to manage stable flies and house flies, including how to use parasitoid wasps as an alternative to pesticides.

Σε έρευνα φάνηκε ότι αποτελεσματική θεραπεία άπνοιας ύπνου οδήγησε σε ουσιαστική βελτίωση των συμπτωμάτων κατάθλιψης, περιλαμβανομένου του αυτοκτονικού ιδεασμού.

Eρευνητές ανακάλυψαν ότι καθώς η καθημερινή πρόσληψη φρούτων και μη αμυλούχων λαχανικών αυξάνεται, ο κίνδυνος μεγάλης αύξησης βάρους μειώνεται.

Giving youth in the emergency department a short intervention during their visit decreased their alcohol consumption and problems related to drinking over the following year, the results of a five-year trial indicate.

Scientists have developed a wearable liquid-based microfluidic tactile sensor that is small, thin, highly flexible and durable. Simple and cost-effective to produce, this novel device is very suitable for applications such as soft robotics, wearable consumer electronics, smart medical prosthetic devices, as well as real-time healthcare monitoring.

An experiment in 2008 laid the foundations for research on 'spin caloritronics' -- a field that aims to develop more effective and energy-saving data processing in information technology. Since then, many new spincaloric effects have been studied, but the key experiment in Japan could not be replicated. Researchers have now found an explanation for this. By applying a new measurement method available at major research facilities, they have also extended the experimental repertoire in spin caloritronics.

Researchers have developed a method for synthesizing organic molecules very selectively, by assembling simple molecules and using an enzyme from E. coli (FSA: D-fructose-6-phosphate aldolase), which acts as a biocatalyst. This is a significant step forward since it replicates the formation of carbohydrates in conditions resembling those that presumably initiated life on the Earth (prebiotic conditions) and because it allows relatively large organic molecules to be obtained very selectively and efficiently. Furthermore, it is a process with few steps, that does not use organic solvents and generates no waste, and it has great potential in chemistry, especially for obtaining molecules and active ingredients of interest (drugs, supplements, etc.).

Scientists have discovered a new gene mutation that causes potentially fatal swelling in unborn and newborn babies. Identifying the gene is the first step toward a future diagnostic test and targeted treatment for this condition.

New research suggests that the movements involved in fidgeting may counteract the adverse health impacts of sitting for long periods.

Machines that are much smaller than the width of a human hair could one day help clean up carbon dioxide pollution in the oceans. Nanoengineers have designed enzyme-functionalized micromotors that rapidly zoom around in water, remove carbon dioxide and convert it into a usable solid form.
