The last time a list was compiled of all the chemicals available on the market and in circulation worldwide, it ran to 100,000 entries. Drawn up shortly after the turn of the millennium, the list focused on markets in the US, Canada and western Europe, which made sense because 20 years ago, these countries accounted for more than two thirds of worldwide chemical sales.

WEST LAFAYETTE, Ind. - Researchers at Purdue University have been working to develop new technologies to help stop the spread of foodborne illnesses, which kill 3,000 people a year, by detecting them more efficiently. They have developed a lanthanide-based assay coupled with a laser that can be used to detect toxins and pathogenic E. coli in food samples, water and a variety of industrial materials.
Yale-affiliated scientist finds that even a few hours' exposure to ambient ultrafine particles common in air pollution may potentially trigger a nonfatal heart attack.
Myocardial infarction is a major form of cardiovascular disease worldwide. Ultrafine particles (UFP) are 100 nanometers or smaller in size. In urban areas, automobile emissions are the primary source of UFP.
Scientists from Far Eastern Federal University (FEFU, Russia), University of Geneva (Switzerland), Minjiang University, and Fuzhou University (China) pointed out WDR74 protein playing an important role in lung cancer and melanoma primary tumors/metastases progression. During the research, the artificially gained WDR74 function brought about a high activity in cancer cells. However, when the function had been dropped cells failed to metastasize becoming more vulnerable to chemotherapy. Related articles are published in Cancer Letters and Oncogene.
There is a strong link between the amount of fast food that pre-school age children consume and their likelihood of becoming overweight or obese, according to a new Dartmouth-led study, published in the journal Pediatric Obesity.
According to the Centers for Disease Control and Prevention, nearly 25 percent of children between the ages of 2 and 5 years are overweight or obese in the U.S. These conditions increase the risk of numerous physical and psychosocial problems during childhood, including fatty liver disease, type 2 diabetes, and depression.
DURHAM, N.C. -- Biomedical engineers from Duke University have demonstrated that, despite significant advancements in protection from ballistics and blunt impacts, modern military helmets are no better at protecting the brain from shock waves created by nearby blasts than their World War I counterparts. And one model in particular, the French Adrian helmet, actually performed better than modern designs in protecting from overhead blasts.
Police use of lethal force in the United States has triggered public scrutiny of violent interactions between police and citizens. Past research has focused on whether race and levels of violence contribute to this phenomenon. A new study expands on prior research by examining the impact of the availability of firearms. It finds a pronounced positive relationship between statewide prevalence of gun ownership by citizens and police use of lethal force.
Researchers at the University of Cambridge have developed a novel technique for generating single photons, by moving single electrons in a specially designed light-emitting diode (LED). This technique, reported in the journal Nature Communications, could help the development of the emerging fields of quantum communication and quantum computation.
February 14, 2020 - For critical care specialists, hepatic failure poses complex challenges unlike those of other critical illnesses. A new set of evidence-based recommendations for management of liver failure is presented in the March issue of Critical Care Medicine, the official journal of the
ROCHESTER, Minn. -- The most common type of heart disease -- coronary artery disease -- affects 6.7% of adults and accounts for 20% of 2 in 10 deaths of adults under age 65. The condition builds over time as inflammation and cholesterol-containing plaques settle in the heart's arteries, where they can eventually cause narrowing and blockages that lead to a heart attack.
Artificial intelligence has been used for the first time to instantly and accurately measure blood flow, in a study led by UCL and Barts Health NHS Trust.
The results were found to be able to predict chances of death, heart attack and stroke, and can be used by doctors to help recommend treatments which could improve a patient's blood flow.
Imagine flipping through your Facebook News Feed first thing in the morning and spotting a notification that your ex is now "in a relationship."
Or maybe the Memories feature shows a photo from that beach vacation you took together last year. Or your ex-lover's new lover's mom shows up under People You May Know.
Scenarios like these are real and not uncommon, according to a new University of Colorado Boulder study exploring how breaking up is even harder to do in the digital age.
In 1988, a 6.9 magnitude earthquake struck near the northern Armenian city of Spitak. The temblor destroyed cities and is estimated to have killed between 25,000 and 35,000 people, many of whom were schoolchildren.
The latest findings from a long-term, UCLA-led study reveal that children who survived the quake and received psychotherapy soon after have experienced health benefits into adulthood.
Researchers at Tomsk Polytechnic University found a method to increase fuel lifetime by 75%. According to the research team, it will significantly increase safety and reduce the operating cost of nuclear power plants in hard-to-reach areas. The study results were published in Nuclear Engineering and Design.
Researchers at the Ruhr-Universität Bochum (RUB) and the University of Duisburg-Essen have developed a new method of depositing catalyst particles to tiny electrodes. It is inexpensive, simple and quick to perform. In order to characterize catalysts and test their potential for various applications, researchers have to fix the particles to electrodes so that they can then be examined, for example, with transmission electron microscopy.
