In 2013, the German Stiftung Warentest found harmful benzene in drinks with cherry flavor. But how did the substance get into the drinks? Was the source benzaldehyde, an essential component of the cherry flavoring? And if so, how could the problem be solved? A new study by the Leibniz-Institute for Food Systems Biology and the Technical University of Munich (TUM) is now able to answer these questions.
Researchers at UCL have developed a new way to make blood stem cells present in the umbilical cord 'more transplantable', a finding in mice which could improve the treatment of a wide range of blood diseases in children and adults.
Blood stem cells, also known as haematopoietic stem cells (HSCs), generate every type of cell in the blood (red cells, white cells and platelets), and are responsible for maintaining blood production throughout life.
A community of flying reptiles that inhabited the Sahara 100 million years ago has been discovered by a University of Portsmouth palaeontologist and an international team of scientists.
Professor David Martill from Portsmouth and researchers from the United States and Morocco identified the three new species of toothed pterosaurs.
The pterosaurs were part of an ancient river ecosystem in Africa that was full of life, including fish, crocodiles, turtles and several predatory dinosaurs.
A new global study reveals the extent to which high-yielding rice varieties favored in the decades since the "Green Revolution" have a propensity to go feral, turning a staple food crop into a weedy scourge.
Study suggests extending school and workplace closures in Wuhan until April, rather than March, would likely delay a second wave of cases until later in the year, relieving pressure on health services
New modelling research, published in The Lancet Public Health journal, suggests that school and workplace closures in Wuhan, China have reduced the number of COVID-19 cases and substantially delayed the epidemic peak--giving the health system the time and opportunity to expand and respond.
A new study in The Economic Journal, published by Oxford University Press, suggests that migrating extremists can shape political developments in their destination regions for generations. Regions in Austria that witnessed an influx of Nazis fleeing the Soviets after WWII are significantly more right-leaning than other parts of the country. There were no such regional differences in far-right values before World War Two.
A species of a lipid that naturally helps skin injuries heal appears to also aid repair of common corneal injuries, even when other conditions, like diabetes, make healing difficult, scientists report.
Their findings show that the lipid DOPG, or dioleoyl-phosphatidylglycerol, aids healing of scratches on the cornea that can result from trauma such as finger pokes or mascara wands.
MINNEAPOLIS - Taking a low-dose aspirin once a day does not reduce the risk of thinking and memory problems caused by mild cognitive impairment or probable Alzheimer's disease, nor does it slow the rate of cognitive decline, according to a large study published in the March 25, 2020, online issue of Neurology®, the medical journal of the American Academy of Neurology.
New York, NY--March 25, 2020--Cardiac arrhythmias are a major cause of morbidity and mortality worldwide. Currently, the 12-lead electrocardiogram (ECG) is the noninvasive clinical gold standard used to diagnose and localize these conditions, but it has limited accuracy, cannot provide an anatomical tool to visually localize the source of the arrhythmia, and depending on which clinician is looking at the signals, there might be some interpretation variability.
Running is great exercise but not everyone feels great doing it. In hopes of boosting physical activity - and possibly creating a new mode of transportation - engineers at Stanford University are studying devices that people could strap to their legs to make running easier.
In experiments with motor-powered systems that mimic such devices - called exoskeleton emulators - the researchers investigated two different modes of running assistance: motor-powered assistance and spring-based assistance. The results, published March 25 in Science Robotics, were surprising.
CORVALLIS, Ore. -- An Oregon State University study published last week found that diabetes education programs that are linguistically and culturally tailored to Latinos lead to significantly higher rates of completion among Latino participants -- even higher than rates among non-Latinos enrolled in the English versions of those programs.
While some of our body's cells divide in a matter of hours, the process of making sperm, meiosis, alone takes about 14 days from start to finish. And fully six of those days are spent in the stage known as the pachytene, when pairs of chromosomes from an individual's mother and father align and connect.
ROCHESTER, Minn. - SARS-CoV-2, the virus that causes COVID-19, continues to spread, leading to more than 20,000 deaths worldwide in less than four months. Efforts are progressing to develop a COVID-19 vaccine, but it's still likely 12 to 18 months away.
From 1946 to 2016, testimony from economists accounted for more than two thirds of all instances of U.S. congressional testimony delivered by social scientists. Thomas Maher of Purdue University, Indiana, and colleagues present these findings in the open-access journal PLOS ONE on March 25, 2020.
Menlo Park, Calif. -- Researchers from the Department of Energy's SLAC National Accelerator Laboratory have discovered a strange new feature of a protein that's thought to be important in the development of tuberculosis: The protein contains a "huge" interior pocket, the likes of which has never before been seen, that appears capable of passing a wide range of other molecules into the bacterial cell.
