More men than women develop Parkinson’s disease and new work presented at the Federation of European Neuroscience Societies says that it is do to sex differences in how brain cells change. Parkinson’s disease affects about 9 million people and becomes increasingly prevalent with age.
Medicine uses Latin because it is a 'dead' language - the meanings of the words will not change over time. But if you want to modernize translations to different languages, an ancient book may help: The Bible.Tools to translate text between languages are widely available - and rather awful. While they can create literal translations, style is hard to bring across without human intervention. If you tried to read a translation of China's Liu Cixin using a computer, you would miss everything, most importantly a great example of the best science-fiction culture since America of the 1950s.
Is your personality set in stone at a young age? If you were a jerk in high school will you still be a jerk at 60? Not necessarily. And what changes there are may not be defining. The only time you might see a big disparity could be when comparing yourself to others.
Recent DNA analyses show that ancient populations in the Peruvian highlands adapted wild tubers into potatoes - and then those potatoes in turn modified them in ways distinct from other global populations.Potatoes are native to South America and became an agricultural crop in the Andean highlands of what is now Peru. But wild tubers genetically modified into potatoes did something interesting in return; they altered the genomes of the Andeans who made it a staple of their diet. Co-evolution. This co-evolution between agriculture and human is evident in the configuration of a gene associated with starch digestion in the small intestine - MGAM - in the agricultural ancient Andean genome samples, but not in hunter-gatherers down the coast.
In 2016, a Respiratory Syncytial Virus (RSV) vaccine candidate named the RSV F Vaccine failed in Phase III trials, which could have been a crippling blow for Novavax, but they may be on the road to recovery. Companies have to have Phase III trials before they can get approval. Phase I proves safety and dosing while Phase II shows it is better than a placebo and Phase III is intended to show it either works better than existing treatments or has fewer side effects. That's all after numerical models and animal studies. Since FDA essentially doubled the costs to get drug approval in the early 2000s only the most promising drug advances to Phase III. perhaps 1 in 5,000 that look good on a computer. It simply isn't worth the cost otherwise.
The protein complex AMPK is thought to suppress cancer, by slowing cellular metabolism, but it can also help some tumors grow.But why? A new study says it has solved the mystery. AMPK acts as a fuel gauge for the cell, overseeing energy input and output to keep the cell running smoothly. Similar to a car sensor flashing a low-gas signal or turning off a vehicle’s AC to save energy, AMPK slows down cell growth and changes the cell’s metabolism if the cell’s fuel (nutrients) is low.
The Great Pyramids have long been held up as the pinnacle of ancient engineering. Over 100 structures, some as high as were constructed of huge alabaster blocks, many quarried from Hatnub - the site of an new interesting discovery.Given the challenges in building such huge structures, it is no surprised the Great Pyramid of Khufu is one of the Seven Wonders of the Ancient World. It and others were built thanks to quarries connected to the Nile by Bronze Age roads. The blocks were transported by sleds. But what about construction? Huge ramps? Were they poured? Some even speculated about aliens.
New molecules similar to carbohydrates have showed the capacity to inhibit the activity of a specific type of glycoside enzymes - and that means inhibiting infectious diseases.Glycosides are essential enzymes to digest carbohydrates but they are also key players in infections caused by pathogens, in anti-bacterial defense and many other vital cellular processes. Because these small molecules that are able to bond with and inhibit the activity of enzymes in infectious diseases, it opens up the basis for new medicines.
In his just published final book, "Brief Answers to the Big Questions," physicist Satephen Hawking wrote, "There is no God. No one directs the universe" but in a universe where only 6% of what must exist is even matter that can be detected, the science community is unwilling to be as definitive as he was.It may be that God is in the gaps, and different people have different definitions for what that is. Yet it may be perpetuating the false narrative that religion is on one pole and science is on another.
Lyme disease is the most prevalent tick-borne disease and is caused by the bacterial spirochete Borrelia. Using the Centers for Disease Control and Prevention (CDC) recommended two-tier method, Garg et al., claim that 72 percent of individuals they examined classified "negative" by the CDC two-tier lyme disease test showed positive for the Borellia biomarker, and other microbes such as Babesia, Bartonella, and Ehrlichia.That means some lyme disease patients do not follow the "one microbe, one disease" Germ Theory, according to an analysis of patients at different disease stages which found they respond to various microbes 65 percent of the time. And that ticks carry more than just lyme disease.
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.
