New lithium-rich battery could last much longer
Battery leverages both iron and oxygen to drive more lithium ions The battery uses both oxygen and iron to store and release electrical energy. Credit: Zhenpeng Yao On paper, it doesn’t seem like Christopher Wolverton’s super lithium-rich battery should work. For one, the novel battery uses iron, an inexpensive metal that has notoriously failed in […]
New desalination method offers low energy alternative to purify salty water
https://www.sciencedaily.com/releases/2018/01/180102171113.htm Date: January 2, 2018 Source: Penn State College of Engineering Summary: Providing safer drinking water to those in need may be a little easier. A new desalination technique is able to remove salt from water using less energy than previous methods. A feed solution contained in a reservoir was separately fed to the […]
Early disease diagnosis could be dramatically improved with new detection system
This is an illustration of the system in action. Credit: Joshua Edel/Imperial College London The presence of, or changes in the concentration of, certain proteins in biological fluids can be indicators of disease. However, in the early stages of disease these ‘biomarkers’ can be difficult to detect, as they are relatively rare. Detecting important biomarkers […]
A radical approach to methane oxidation into methanol
Researchers convert methane to valuable chemicals using clean, low-temperature radical reaction Chlorine dioxide radical (ClO2•) was found to act as an efficient oxidizing agent in the aerobic oxygenation of methane to methanol and formic acid under photoirradiation. The yields of methanol and formic acid were 14% and 85%, respectively, with a methane conversion of 99% […]

XXV EFMC International Symposium on Medicinal Chemistry
EFMC-ISMC 2018 XXV EFMC International Symposium on Medicinal Chemistry Ljubljana, Slovenia – September 2-6, 2018 The XXV EFMC International Symposium on Medicinal Chemistry (EFMC-ISMC 2018) will be organised by the Section for Medicinal Chemistry of the Slovenian Pharmaceutical Society (SFD), on behalf of the European Federation for Medicinal Chemistry (EFMC). The EFMC is the main […]
Faster, more accurate cancer detection using nanoparticles
This illustration shows how human breast cancer cells in a mouse model were “chased” with novel rare earth nanoscale probes injected intravenously. When the subject is illuminated, the probes glow in an infrared range of light that is more sensitive than other optical forms of illumination. In this case, the probes show the spread of […]
The origin of water's unusual properties found
Illustration showing fluctuations between regions of two different local structures (high density as red and low density liquid as blue) of water that depend on the temperature. Maxima in the thermodynamic response and correlation functions are observed as a function of temperature, when the numbers of molecules in the two structures become equal, resulting in […]
Life on the ice: For the first time scientists have directly observed living bacteria in polar ice and snow
The research team positioned themselves away from polar wildlife to limit contamination, but one persistently curious character meant a testing site had to be abandoned. Credit: James Chong For the first time scientists have directly observed living bacteria in polar ice and snow — an environment once considered sterile. The new evidence has the […]
Fructose
Super-sweet and packed with preserving power, Mike Freemantle discovers that fructose can help keep things fresh long after the sell-by date By Ben Valsler There are some drinks that many people only consume at this time of year – mulled wine or cider, sloe gin, maybe sherry and port, or even novelty ‘christmas spice’ beers. […]
Designer nanoparticles destroy a broad array of viruses

Credit: Petr Kral Viral infections kill millions of people worldwide every year, but currently available antiviral drugs are limited in that they mostly act against one or a small handful of related viruses. A few broad-spectrum drugs that prevent […]
Viruses can transfer genes across the superkingdoms of life
Rendering of a virus. New research shows that viruses can transfer genes to organisms that they aren’t known to infect — including organisms in different superkingdoms, or domains. The study, published in open-access journal Frontiers in Microbiology, also finds that viruses and cellular organisms share a large group of genes that help cells to function, […]
