Around 65 million years ago, a massive asteroid crashed into the Gulf of Mexico, causing an impact so huge that the blast and its aftermath wiped out about 75 percent of all life on Earth, including most of the dinosaurs. It’s known as the Chicxulub impact and it may possibly have created habitats for our early life on Earth because the asteroid hit the Earth’s surface with such force that it pushed rocks – at the time about 6 miles beneath the surface – farther downward and then outward.
In a 2015 analysis, antibiotic resistance continued to increase for most bacteria and antibiotics under surveillance. It is worrying to see increased resistance to last-line antibiotics, but we still have time to turn the tide and ensure that antibiotics remain effective.
In particular, the EU average percentage of carbapenem resistance in Klebsiella pneumoniae increased from 6.2% in 2012 to 8.1% in 2015, and combined resistance to carbapenems and polymyxins (e.g. colistin) was sometimes reported. These two groups of antibiotics are considered last-line antibiotics as they usually are the last treatment options for patients infected with bacteria resistant to other available antibiotics.
You should not smoke cigarettes and if you already do, you should stop. Though the U.S. FDA has damaged the smoking cessation possibilities for current users, and California has outright subsidized cigarette companies with punitive taxes on vaping, there may still be ways to limit the destructive potential of cigarettes: Red wine.
A new test with molluscs - freshwater mudsnails (Potamopyrgus antipodarum) - may enable manufacturers of chemicals and drugs to check their products for harmful effects on reproduction, and avoid the hype and scaremongering of environmental groups.
Though any potential benefits of marijuana are unknown - claims are anecdotal and no different than the claims about kratom or acupuncture - a group is contending that it can nonetheless help with the other popular buzz term of 2016: Opioid addiction.
But there is a caveat. The determination in Clinical Psychology Review was made by a systematic review. If homeopaths want to show that homeopathy works, they simply do a review of homeopathy papers. That doesn't mean it works and so another review won't do much to assuage fears that marijuana addiction is trading one problem for another - in this case, toxic chemicals inhaled in smoke for pain relief that may not be evident.
Though DSM-5 is considered nothing more than a glossary by the National Institute of Mental Health, it continues to be used as a diagnostic tool by clinical practitioners. As a result, Psychiatric disturbances are all too often diagnosed as schizophrenia. ‘Personalized medicine’ may offer the solution.
The symptoms that we define as ‘schizophrenia’ are among the most serious that can befall a person. In the international literature schizophrenia is no longer regarded as a single illness, but as a group of separate conditions, some of which have yet to be defined. A public debate has grown up on this issue, and there are a number of people who support the statement that 'schizophrenia' doesn't actually exist.'
