Doctors, pilots, air traffic controllers and bus drivers have at least one thing in common—if they're exhausted at work, they could be putting lives at risk. But don't toss yours in the bin just yet. In reality it is very difficult to say to what degree some piece of evidence can support a case against a crime suspect. This has prompted a need for effective tools for police to determine on. Chemists from Trinity College Dublin, in collaboration with RCSI, have devised a revolutionary new scanning technique that produces extremely high-res 3D images of bones—without exposing patients to X-ray radiation.

Imagine a DNA photocopier small enough to hold in your hand that could identify the bacteria or virus causing an infection even before the symptoms appear. With the legalization of medical and recreational marijuana spreading across the country, the drug's use is reportedly increasing among pregnant women. Certain substances, such as the neurotransmitter GABA (gamma aminobutyric acid), are important signal substances throughout the central nervous. Washington State University researchers have developed a low-cost, portable laboratory on a smartphone that can analyze several samples at once to catch a cancer biomarker, producing lab quality results. Researchers at The University of Texas at Dallas are sweating the small stuff in their efforts to develop a wearable device that can monitor an individual's glucose level via perspiration on the skin. University of Leicester researchers have developed a new approach for analysing toxic chemicals in complex samples that mimics the way mammals smell and taste. A new type of imaging technology uses the mid-infrared part of the spectrum and thermal lensing to visualize living cells and organisms, an innovation that could bring insights into drug delivery and cancer treatment. A new device for studying tumor cells can trap 10,000 individual cells in a single chip. This November, several states will vote whether to legalize marijuana use, joining more than 20 states that already allow some form of cannabis use. Perena Gouma, a professor in the Materials Science and Engineering Department at The University of Texas at Arlington, has published an article in the journal Sensors that describes her invention of a hand-held breath monitor. An oversight in a radioisotope dating technique used to date everything from meteorites to geologic samples means that scientists have likely overestimated the age of many samples, according to new research from North Carolina. Conservation and preservation of historical monuments as well as of single artworks of our cultural heritage are receiving increasing attention. In fact, 60% of all those stopped by police under suspicion of drug-driving test positive for illegal. Academics in the University of Surrey's Department of Chemistry have developed a new diagnostic test for cocaine and benzoylecgonine (the main metabolite for cocaine) in urine and oral fluid. Now scientists.

Swapping delicate microscopic flow valves for a universal modular valve system has enabled A*STAR researchers to dramatically decrease the cost and complexity of microfluidic diagnostic chips—business card-sized devices. DNA-evidence is often believed to be a damning evidence, which leaves no space for uncertainty. Scientists studying the unique fruit have now analyzed. Just like an alphabet is made up of individual letters, DNA is composed of chemical bases. An EU-funded project is working on smartphones'. In the future, it will be possible to carry out tests of new drugs on bacteria much more efficiently using microfluidic devices, in which each of the thousands of droplets moving through the microchannels can act as separate. Before a malignant tumor develops, the immune system tries to fight against its altered proteins by producing certain cancer antibodies. The exact way that atoms bond to a solid surface. The fruit's yellowish flesh is sweet and custard-like, but it comes with an overpowering stench of garbage. It's a method they plan to use in new research to help uncover when antioxidant levels. Over 8,000 people were arrested in England and Wales for driving under the influence of drugs in the year to April 2016. Analytical chemistry lab reports. That could drastically reduce the estimated. Researchers used super-X-ray vision to peer beneath the surface of a portrait by impressionist Edgar Degas and gaze upon the model whose likeness he painted over nearly 140 years ago, they reported Thursday. A new company will commercialize sensing technology invented at Harvard University that can perform instant, in-field characterization of the chemical make-up and material properties of unknown liquids. While previous studies have found that electronic cigarettes emit toxic compounds, a new study from Lawrence Berkeley National Laboratory (Berkeley Lab) has pinpointed the source of these emissions and shown how factors such. Researchers at the University of British Columbia and the Paul Scherrer Institut (PSI) in Switzerland have created a microneedle drug monitoring system helpful site that could one day replace costly, invasive blood draws and improve patient. The counterfeit drug industry is thriving. Criminals are cashing in on an estimated $200 billion in profits – nearly 10 percent of pharmaceuticals worldwide – while unknowing consumers put their health or even lives at. And in the same way that letters must be placed in a specific order to form words and sentences, the sequence of chemical bases is.

It has been said that spending too much time on a smartphone can negatively impact brain development or even cause damage to the neck. The research, which was conducted. Scientists have developed a type of HIV test on a USB stick. Our nerve and muscle cells send signals to each other using ions and molecules. E. coli can be transmitted in contaminated food and water, posing particular. A portable power-free test for the rapid detection of bacterial resistance to antibiotics has been developed by academics at Loughborough University and the University of Reading. A new device developed by researchers at MIT and a physician at Connecticut Children's Medical Center could greatly improve doctors' ability to accurately diagnose ear infections. Drawing on biology, chemistry, genetics, medicine and psychology, forensic evidence helps answer questions. In 1986, Gordon Brown used SLAC's Stanford Synchrotron Radiation Lightsource (SSRL) to visualize something no one had ever seen before: In the online magazine ChemViews, Austrian scientists take a view on the current. A simple chemistry method could vastly enhance how scientists search for signs of life on other planets. Researchers from King's working with the European Forensic Genetics Network of Excellence (EUROFORGEN) are launching a guide in partnership with the charity Sense about Science, to address misconceptions about DNA analysis. Most people who have tried durian either love it or hate it. It stands to reason that many of these women will continue to use marijuana. Researchers have invented a range of instruments from giant telescopes to rovers to search for life in outer space, but so far, these efforts have yielded no definitive evidence that it exists beyond Earth. That's. Using powerful new tools, scientists from the RIKEN SPring-8 Center and collaborators have demonstrated how bacteriorhodopsin, a proton pump, uses light to transport protons across the cell membrane to create a charge difference. An exciting X-ray imaging technology has been successfully developed to the point where it is now ready for translation into all kinds of beneficial applications, including potentially life-saving uses in security and healthcare. A new technique offers better sensitivity and accuracy in detecting an essential biomarker of cancer and inflammatory diseases. Forensic science has become a mainstay of many a TV drama, and it's just as important in real-life criminal trials.
