Intermittent fasting, and fasting in general, has been a popular fad health gimmick, but the science isn't on its side. Instead, proponents believe mice are little people so if mice weaned on starvation diets lived longer, people would also.
Usually, it takes a nose to smell, but now - for the first time - scientists have developed a convincing model able to measure odours from pig farms by means of precise measurements of the content of odorants in the atmosphere.
How much and how bad does pig production facilities smell? Now we are able to answer this question by means of a technique developed by scientists from Department of Engineering, Aarhus University, in cooperation with SEGES. They have developed a model that is able to predict pig house odours. The model is based on measurements of odorants by means of the analytical technique PTR-MS.
Alpine forests will be at great risk should weather phenomena such as droughts and torrential rain become more frequent. As a study by the Technical University of Munich (TUM) shows, the mountain forests of the Bavarian Alps have seen a significant reduction in topsoil organic matter over the past three decades. The study authors' recommendation is therefore to preserve, or better still, increase soil humus regardless of climate change by implementing humus-promoting forest management to safeguard the mountain forest's protective function and to mitigate floods.
A Kobe University research group including Associate Professor Maki Hideshi (Center for Environmental Management), PhD candidate Sakata Genki (Graduate School of Engineering, Department of Chemical Science and Engineering, currently employed at Central Glass Co., Ltd.) and Professor Mizuhata Minoru (Graduate School of Engineering) have developed a new analysis method that uses magnetic fields to quickly and accurately measure the concentration of aluminum used to purify tap water. These findings can potentially be used in developing efficient and environmentally-conscious coagulants for water treatment. The findings were presented on May 29, 2016 at the 76th Japan Society for Analytical Chemistry Symposium.
Philadelphia, PA, June 20, 2016 - Cannabis use during pregnancy is associated with abnormal brain structure in children, according to a new study in Biological Psychiatry.
Compared with unexposed children, those who were prenatally exposed to cannabis had a thicker prefrontal cortex, a region of the brain involved in complex cognition, decision-making, and working memory.
Author of the study Dr. Hanan El Marroun, of Erasmus University Medical Center in The Netherlands, said: "this study is important because cannabis use during pregnancy is relatively common and we know very little about the potential consequences of cannabis exposure during pregnancy and brain development later in life."
As Republican and Democratic parties prepare for national conventions this summer, campaign speeches are filled with promises about everything from health care to the economy and national security.
But a national poll suggests presumptive presidential candidates Hillary Clinton and Donald Trump may want to consider their positions on a less-talked about topic: children's health.
Greenland's glaciers are melting, but they do that every year. However, a recent computer simulation sounds the alarm about a 50 percent increase in the freshwater flux since 1990, which is too narrow a timeframe for scientific purposes, it is the target date for the original Kyoto treaty on global warming, but will be a clarion for policy makers.
Whole Foods shoppers and other anti-science groups may not like it, but scientists have taken the first step of an ongoing-process designed to bring a valuable heirloom wheat back from the brink of extinction.
Solar energy wants to become an alternative source to fossil fuels but no one wants to incur the much higher cost required by continued subsidies. Rather than trying to create large solar farms, which are invariably blocked by environmental lawsuits, the move is on to go small and avoid regulations - that means on buildings, clothes, consumer electronics and wearables. This necessitates ultra-thin film, low-cost and ideally flexible solar cells without compromising the environment during production, use, or disposal.
Chronic myeloid leukemia (CML) develops through chromosomal alterations in blood-forming cells of the bone marrow and usually occurs in older persons. Around 20 percent of adults diagnosed with leukemia suffer from this type of blood cancer.
We know water is essential to life as we know it, but why?
A paper in Proceedings of the National Academy of Sciences provides strongest evidence that proteins--the large and complex molecules that fold into particular shapes to enable biological reactions--can't fold themselves. Rather, the work of folding is done by much smaller water molecules, which surround proteins and push and pull at them to make them fold a certain way in fractions of a second, like scores of tiny origami artists folding a giant sheet of paper at blazingly fast speeds.
Researchers of Aalto University have developed surfaces where oil transports itself to desired directions. Researchers' oleophobic surfaces are microtextured with radial arrays of undercut stripes. When oil drops fall on surfaces, drops move away from the landing point to the direction set by asymmetric geometrical patterning of the surface. The surfaces open up new avenues for power-free liquid transportation and oil contamination self-removal applications in analytical and fluidic devices.
- We developed surfaces that are able to move liquid oil droplets by surface tension forces. Droplets from anywhere within the pattern will spontaneously move to the center of the pattern, tells Postdoctoral Researcher Ville Jokinen.
Buddy Dyer, a government worker in Orlando, stated, at approximately 12:30 PM on Sunday, June 12, 2016, soon after the mass shootings in Orlando, that the most important thing right now is to waive the HIPAA laws so the physicians taking care of 53 injured patients can communicate with their distraught family members.
