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.
Anti-gun proponents like to produce headlines showing a young child accidentally shot another family member with a pistol, but that kind of cultural framing may be doing more harm than good, because a new study reaffirms what most gun owners knew: Gun harm is not caused by lazy or irresponsible gun owners letting their kids get them by mistake, it is from assaults by men. And teenagers at greatest risk for committing acts of violence are at greatest risk of receiving it, not pre-schoolers.Of the over 75,000 youths who visited emergency rooms for gun-related injuries from 2006 to 2014, 86.2 percent were males and overwhelmingly in large cities.
Fake news has become a common claim, and for good reason. The Russians, for example, have been caught using environmentalists, food activists, "journalism" professors, and trade groups to promote fear and doubt about American science and technology.But organic food shoppers and people scared of natural gas are not alone in believing fake news. A new study shows that dogmatic individuals, fundamentalists and delusional people of all kinds are more likely to believe fake news. The less open-minded a person is, the more likely they are to be swayed by fake news claims.
Before the arrival of European immigrants to the western United States, up to 12 percent of it would burn each year. Somehow, even though science is well aware of that fact, political media today claim that wildfires are unprecedented and we are doomed. A new study notes again that the amount of wildfire occurring in the western U.S. remains far below the acreage burning when native Americans were not managing the ecology. The context is not to debunk modern beliefs about how superior native Americans were, but to talk about water.
Using FORS2, an instrument mounted on ESO’s Very Large Telescope, government astronomers have observed the active star-forming region NGC 2467 — the Skull and Crossbones Nebula, called such because of the dust, gas and bright young stars gravitationally bound into the form of a grinning skull.NGC 2467 skulks in the constellation Puppis, which translates rather unromantically as The Poop Deck. And this was taken in March, but released near Halloween, so ESO has something to talk about.
What would it take to grow potatoes or tomatoes in space? Some mycorrhiza, it turns out. Currently NASA can't even get a telescope into space without being wildly over budget and 10 years behind schedule so they are not putting colonies on the moon any time soon. But the private sector might. And if that is going to be more than the plot of a film, it will take agriculture.
Beer, the most popular alcoholic drink in the world, consumes around 17% of global barley production, but this share varies across major beer-producing countries; 83% in Brazil to 9% in Australia. What if global warming hits and temperatures rise more than 0.1 Celsius that has happened so far? Less barley, less beer. The vulnerability of beer supply to such extremes has never been assessed but a new estimate is sure to spur action, at least if you believe in estimates.
Does the presence of higher levels of biomarkers of dairy fat consumption in people with lower levels of type 2 diabetes mean more dairy means less risk of developing it? According to epidemiology, yes, but epidemiology and politics are the two key reasons public confidence in academic science have plummeted.
Where does magma gather in the earth's crust? And for how long? With worldwide poverty in decline, plentiful food thanks to science, and life expectancies increasing each year, we can turn to more remote worries - and learn some new things in the process. Like about volcanic eruptions and magma.
Would famous Apple CEO Steve Jobs be alive today if he had accepted science the same way he accepted technology? Pancreatic cancer will kill half of patients but he guaranteed his death when he waited 9 months after his 2003 diagnosis to have surgery that could have saved his life, instead opting for belief that medicine was bad and alternatives were just as legitimate.
An analysis of over 400,000 people's self-reported drinking habits finds that statistically drinking alcohol 4 or more times per week increases the risk of premature death by 20 percent. The increased risk was consistent across age groups.
Vaccines are the most effective way to prevent and eradicate infectious diseases but many vaccines have to be manufactured in cell culture or eggs, which is expensive, and most vaccines must be kept refrigerated during the transport
It takes a few years, a lot of grain and even more water to make a steer big enough to send to market - a company wants to get that process down to a few weeks.
