A chemical sensor prototype developed at the University of Michigan will be able to detect 'single-fingerprint quantities' of substances from a distance of more than 100 feet away, and its developers are working to shrink it to the size of a shoebox.

Genetic study uncovers fungal sex secrets, which shed light on candidiasis

Jue, 12/14/2017 - 23:00
A new genetic analysis of fungal yeast infections (candidiasis) from around the world has revealed surprising secrets about how these microbes reproduce and cause disease, according to a new study published in Current Biology from researchers at the Centre for Genomic Regulation in Barcelona, Spain.

Quantum memory with record-breaking capacity based on laser-cooled atoms

Jue, 12/14/2017 - 23:00
The emerging domain of parallelized quantum information processing opens up new possibilities for precise measurements, communication and imaging. Precise control of multiple stored photons allows efficient handling of this subtle information in large amounts. In the Quantum Memories Laboratory at Faculty of Physics, University of Warsaw a group of laser-cooled atoms has been used as a memory which can store simultaneously up to 665 quantum states of light. The experimental results have been published in a prestigious Nature Communications journal.

Extending food safety training to other countries could save live

Jue, 12/14/2017 - 23:00
Food safety practices that Americans take for granted -- washing hands with soap, refrigeration, and not cutting raw meat and vegetables on the same surface without disinfection -- are not widely practiced in other places around the world, and researchers in Penn State's College of Agricultural Sciences want to change that.

Scientific achievements during the operation of Lomonosov satellite

Jue, 12/14/2017 - 23:00
The Lomonosov Project is a large-scale scientific and educational space project of Lomonosov Moscow State University aimed at studying space phenomena. In the course of operation of Lomonosov satellite on the orbit the team of Skobeltsyn Scientific and Research Institute of Nuclear Physics, MSU received new data on many understudied physical phenomena both in the Universe and in the atmosphere of the Earth.

3-D nanoscale imaging made possible

Jue, 12/14/2017 - 23:00
In a research article '3D Nano-scale Imaging by Plasmonic Brownian Microscopy' published today in Nanophotonics, the team around Prof. Xiang Zhang from the University of California in Berkeley demonstrate a method for meeting this challenge with stunning properties.

More electronic materials opened up with new metal-organic framework

Jue, 12/14/2017 - 23:00
More materials for electronic applications could be identified, thanks to the discovery of a new metal-organic framework (MOF) that displays electrical semiconduction with a record high photoresponsivity, by a global research collaboration involving the University of Warwick.

New chronic kidney disease audit published

Jue, 12/14/2017 - 23:00
Sustainability and Transformation Partnerships, Clinical Commissioning Groups and primary care practices must all work together to improve outcomes for patients with Chronic Kidney Disease (CKD), according to the national Chronic Kidney Disease Audit published today. The Audit was commissioned by the Healthcare Quality Improvement Partnership (HQIP) and conducted by the Informatica Systems, the London School of Hygiene & Tropical Medicine, UCL (University College London) and Queen Mary University of London.

Vitamin deficiency in later life

Jue, 12/14/2017 - 23:00
One in two persons aged 65 and above has suboptimal levels of vitamin D in the blood. This is the conclusion of an investigation conducted by researchers at the Helmholtz Zentrum München, as part of the population-based KORA-Age study in the region of Augsburg. Moreover, as the authors of the study report in the peer-reviewed journal Nutrients, one in four older adults has suboptimal vitamin B12 levels.

Health and spirituality values influence attendance for pelvic-floor dysfunction treatment

Jue, 12/14/2017 - 23:00
New research from psychologists and health professionals in Swansea has found that the types of life values that patients hold affect their attendance at medical treatment for pelvic-floor dysfunction, a condition affecting over 25 percent of all women in the UK.

Real-time observation of collective quantum modes

Jue, 12/14/2017 - 23:00
When symmetries in quantum systems are spontaneously broken, the collective excitation modes change in characteristic ways. Researchers at ETH have now directly observed such Goldstone and Higgs modes for the first time.

Russian scientists developed a new technology of energy generation from bituminous coal

Jue, 12/14/2017 - 23:00
A team from Ural Federal University (UrFU) developed a new efficient technology of electrical power generation from bituminous coal. The results of the study were published in International Journal of Hydrogen Energy.

Record high photoconductivity for new metal-organic framework material

Jue, 12/14/2017 - 23:00
An international team of scientists, from the University of Surrey, University of São Paulo (Brazil), the University of Warwick and the University of Grenoble-Alpes (France), has created a new metal-organic framework (MOF) that has shown record-high photo-conductivity levels for a material of its type.

Distinct human mutations can alter the effect of medicine

Jue, 12/14/2017 - 23:00
About one third of all medicine binds to the same type of receptor in the human body. An estimated 3 percent of the population have receptors of this type that are so genetically different that they are predisposed to altered, ineffective or adverse responses to medicine, a new study from the University of Copenhagen and the MRC Laboratory of Molecular Biology in Cambridge shows.

The hazards of antibiotic resistances remain high

Jue, 12/14/2017 - 23:00
According to a survey among researchers, it is difficult to quantify the true extent of the hazards of antibiotic resistances to humankind. The survey conducted by Freie Universität Berlin and Karlsruhe Institute of Technology (KIT) will be introduced on the occasion of the international World Antibiotic Awareness Week on Sunday, Nov. 19. It reveals that among researchers worldwide, there is broad agreement on the fact that antibiotic resistances are serious health hazards. The number of related deaths, however, cannot be determined reliably.

KAIST team develops technology to find optimum drug target for cancer

Jue, 12/14/2017 - 23:00
A KAIST research team led by Professor Kwang-Hyun Cho of the Department of Bio and Brain Engineering developed technology to find the optimum drug target according to the type of cancer cell. The team used systems biology to analyze molecular network dynamics that reflect genetic mutations in cancer cells and to predict drug response. The technology could contribute greatly to future anti-cancer drug development.

Scientists Describe the Structure of a Prospective Luminesce Substance

Jue, 12/14/2017 - 23:00
A physicist from Siberian Federal University (SFU) and Kirensky Institute of Physics Federal Research Center KSC SB RAS (IF) described the structure and properties of a new substance obtained by his Chinese colleagues. These are layered crystals of rare earth metal hydroxides Ln2(OH)4SO4 (Ln=Eu-Lu, Y) that may acts as eco-friendly sources of phosphors (substances that transform different energies into emission of light) for panels, screens, and other electronic devices. The discovery was reported by Chemistry: A European Journal.
