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.
By using infrared wavelengths, the HAWK-I infrared imager mounted on ESO's Very Large Telescope (VLT) in Chile was able to capture this image of the star cluster RCW 38.RCW 38 is over 5,00 light years away (look toward the constellation Vela) and is composed of several short-lived massive stars that will eventually supernovae, but also has some 8,000 other x-ray emitting objects.
In Ely, about 250 north of Las Vegas, Nevada is scheduled to hold its first execution in 12 years.Nothing controversial about that, because in 2002 Scott Dozier murdered Jeremiah Miller after he traveled to Las Vegas where Dozier had promised to help him make methamphetamine. Dozier dumped him in a trash bin, three years later killed at least one other person, and has been on "death row" since 2007. And nothing controversial about Dozier wanting to die rather than spend the rest of his life in prison.
Genetic testing has been overcome by companies selling hype. Even 23andMe, arguably the most prominent, was chastised by FDA for promising peace of mind when they couldn't do anything of the kind.What about actual research involving the testing of human biospecimens? Should individual research results on a study-specific basis be done through an informed decision-making process? If so, how? And when?
Seabirds love fish and fishing nets are a ready source of food. Peru's gillnet fleet comprises the largest component of that nation's small-scale fleet and is conservatively estimated to set 100,000 kilometers of net per year in which thousands of turtles and seabirds die as "bycatch" or unintentionally.
Five years ago, California set out to be a world leader in adopting ambitious greenhouse gas reduction targets and created the world's fourth-largest carbon-trading program. Not bad for one state.Except it isn't helping the state, it is subsidizing others. And some of the emissions targets are not emissions at all, they are instead epidemiological claims like small micron particulate matter (PM2.5), which have had zero acute deaths but were the target of EPA and California environmentalists despite a lack of evidence.
Worldwide poverty has dropped dramatically, we are in the Long Peace when it comes to war, the old cycles of famine boom and bust have leveled off, science has made it possible for everyone to live better for longer and spend less on basic necessities.The world continues to improve. Why, then, do polls consistently show that people believe otherwise? The answer may lie in a phenomenon called "prevalence induced concept change."
Fear is a healthy response, kept intact over eons of evolution, but sometimes it can be irrational. A new brain circuit discovery may help make sense of the madness. The study details the role of dopamine in ensuring that rats stop being afraid when there isn't anything to be afraid of anymore.
There is talk in America of adding even more nutrition information to food labels, but as long as entire industries are exempt from evidence-based claims, it won't do much good. It will still be woo central in the supplement, holistic, and weight-loss camps.The European Association for the Study of Obesity investigated the legality of on-pack nutrition and health claims routinely found on commercially available meal replacement shakes for sale in the UK and found that over 75 percent are in violation of EU Nutrition and Health Claims regulations.
Like many Americans, like many people in all rich nations, New Yorkers somehow still have a lot of be depressed about. And they are getting obese. And not sleeping enough. In 2006, New York declared if they just banned trans fats, diabetes would go down, but rates actually went up, and outside the wealthy white demographic it has remained high.
Yet New Yorkers think they are healthy.
Mounting levels of atmospheric carbon dioxide reduce the medicinal properties of milkweed plants that protect monarch butterflies from disease, according to a recent experiment.
Barometric pressure, tides, winds, waves, they all play a role in the ebb and flow of the ocean. A new study finds that that river outflow could play a role in sea level change as well. By examining decades' worth of river level and tidal data from gauges installed throughout the eastern United States. and combining that data with information on water density, salinity, and the Earth's rotation, they created a mathematical model that describes the link between river discharge and sea level on an annual basis.
The oldest colors in the geological record have been discovered. At 1.1 billion-years-old, the bright pink pigments extracted from marine black shales of the Taoudeni Basin in Mauritania, West Africa, are actually molecular fossils of chlorophyll that were produced by ancient photosynthetic organisms - cyanobacteria.The fossils range from blood red to deep purple in their concentrated form, and bright pink when diluted and are more than half a billion years older than previous pigment discoveries. The rocks deep beneath the Sahara desert in Africa, remnants of an ancient ocean that has long since vanished, were rocks to powder (yes, you read that right, but nature has a lot more) before extracting and analyzing molecules of ancient organisms from them.
