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.
People who smoke marijuana and are considering having children in the future need to be aware about four serious issues that may impact both men and women according to an article ("Five things to know about ... marijuana and fertility" - the title says five things, but there are only four, the fifth is a plea to send more money) in CMAJ (Canadian Medical Association Journal).The following is useful information for people who may want to conceive. Four things to know about marijuana and fertility:
Scientists continue to gain ground in the race against wheat stem rust, a pathogen that threatens global food security because of its ability to kill wheat. The new chink in nature's armor was discovered in the first rust virulence molecule that wheat plants detect to 'switch on' built-in resistance and stave off the disease.
Dog owners insist that 'all dogs are puppies', which means our beliefs about their cuteness are not conditional on age, but a paper in Anthrozoos: A Multidisciplinary Journal of the Interactions of People and Animals, suggests otherwise. The authors found that dogs' attractiveness to humans peaks at roughly eight weeks, the same point in time at which their mother weans them and leaves them to fend for themselves.
To many in the west, Siberia is synonymous with remote winter gulags where dissidents go to die. A new simulation estimates that if climate change occurs according to more aggressive models, the end of the century might see it as a pretty nice place to love. Russia east of the Urals towards the Pacific accounts for 77 percent of Russia's land area - 13 million square kilometers. Its population, however, is just 27 percent and is concentrated along the forest-steppe in the south, which has a comfortable climate and fertile soil.
There are lots of paradoxes in nature but one - how earthquakes along mid-ocean ridges are linked with low tides - may have revealed a mechanism. The mechanism is the magma below the mid-ocean ridges."It's the magma chamber breathing, expanding and contracting due to the tides, that's making the faults move," says Christopher Scholz, a seismologist at Columbia University's Lamont-Doherty Earth Observatory.Low tide correlation to earthquakes is surprising because of the way the mid-ocean fault moves. The fault as a tilted plane that separates two blocks of earth. During movement, the upper block slides down with respect to the lower one.
Though the U.S. government and its hand-picked panel are claiming that the "opioid epidemic" is legitimate pain patients getting hooked on drugs because of lazy doctors and greedy pharmaceutical companies, the reality is much different. Only a small number of people considered addicted to opiods are not instead recreational users.
The movie version of scientists is a lone scientist having a "Eureka!" moment in a laboratory - thanks, Archimedes. In modern times, for example, ecoterrorists attack because humanity is a plague, science creates a cure, we are saved, or a scientist is a myopic tinkerer who creates a virus and government wants to weaponize it, etc.(1)
A new look at data tracked the diets, health and lifestyle habits of nearly 30,000 adults across the country for as long as 31 years has concluded that the risk of heart disease and death increases with the number of eggs an individual consumes.The epidemiology paper believes that is due to the cholesterol.
Health care has become political and that means everyone wants everything for little money, at least when it comes to their own treatment or those in their family. The other edge of the political sword is lawyers waiting to sue, which has led to high malpractice costs and even higher costs due to "defensive medicine" - running unnecessary tests and engaging in procedures doctors know aren't valuable in order to check off boxes if a lawsuit happens.
Though every world science body sees no reason to be concerned about genetic engineering - hundreds of millions of humans and billions of animals have been fine with a gene in one plant that is simply found naturally in another plant, as you'd expect - well funded activist campaigns about "Frankenfoods" have largely succeeded. Organic food has ballooned in revenue using claims it claims no GMOs all while not mentioning their own less precise genetic engineering; mutagenesis, bathing organisms in chemicals and radiation to get a desired effect.
Researchers doing observations in Myanmar's Htamanthi Wildlife Sanctuary found that rain-filled tracks of Asian elephants (Elephas maximus) were filled with frog egg masses and tadpoles. The tracks can persist for a year or more and provide temporary habitat during the dry season. Trackways could also function as "stepping stones" that connect frog populations.
US Stem Cell Clinic LLC, of Weston, Florida, and US Stem Cell Inc., of Sunrise, Florida, and their Chief Scientific Officer Kristin Comella, Ph.D. have adulterated and misbranded a stem cell drug product made from a patient’s adipose tissue, U.S. District Judge Ursula Ungaro of the Southern District of Florida declared in a summary judgment against the defendants.On behalf of FDA, The U.S. Department of Justice filed for a permanent injunction against the defendants in May 2018, after several attempts to provide the clinic and the individual defendants the opportunity to work with the agency to come into compliance with FDA regulations and protect patients from harm.
