[Q]: In a study in the British Journal of Psychiatry, researchers analyzed comedians from Australia, Britain and the United States and found they scored significantly higher on four types of psychotic characteristics compared to a control group of people who had non-creative jobs. The traits included a tendency towards impulsive or anti-social behavior, and a tendency to avoid intimacy. “The creative elements needed to produce humor are strikingly similar to those characterizing the cognitive style of people with psychosis - both schizophrenia and bipolar disorder,” said Gordon Claridge of the University of Oxford’s department of experimental psychology, who led the study. Although the traits in question are known as “psychotic”, Claridge said, they can also represent healthy equivalents of features such as moodiness, social introversion and the tendency to lateral thinking. “Although schizophrenic psychosis itself can be detrimental to humor, in its lesser form it can increase people’s ability to associate odd or unusual things or to think ‘outside the box’,” he said. “Equally, manic thinking - which is common in people with bipolar disorder - may help people combine ideas to form new, original and humorous connections.”  The researchers recruited 523 comedians - 404 men and 119 women - and asked them to complete an online questionnaire designed to measure psychotic traits in healthy people. The traits scored were “unusual experiences”, such as belief in telepathy and paranormal events, “cognitive disorganization” such as difficulty in focusing thoughts, “introvertive anhedonia” - reduced ability to feel social and physical pleasure, and “impulsive non-conformity”, or tendency towards impulsive, antisocial behavior. The same questionnaire was also completed by 364 actors - who are also used to performing in front of an audience - as a control group, and the comedians’ and actors’ results were compared to each other as well as a general group of 831 people who had non-creative jobs. The researchers found that comedians scored significantly higher on all four types of psychotic personality traits compared to the general group. Most striking were their high scores for impulsive non-conformity and introverted personality traits, the researchers said. The actors scored higher than the general group on three types - but did not display high levels of introverted personality traits.

[Q]: Scientists said on Wednesday many Tibetans possess a rare variant of a gene involved in carrying oxygen in the blood that they likely inherited from an enigmatic group of extinct humans who interbred with our species tens of thousands of years ago. It enables Tibetans to function well in low oxygen levels at elevations upwards of 15,000 feet (4,500 meters) like the vast high plateau of southwestern China. People without this variant would be apt to develop thick blood, leading to high blood pressure, heart attacks, strokes, low-birth-weight babies and higher infant mortality. This version of the EPAS1 gene is nearly identical to one found in Denisovans, a lineage related to Neanderthals - but is very different from other people today. Denisovans are known from a single finger bone and two teeth found in a Siberian cave. DNA testing on the 41,000-year-old bone indicated Denisovans were distinct from our species and Neanderthals. “Our finding may suggest that the exchange of genes through mating with extinct species may be more important in human evolution than previously thought,” said Rasmus Nielsen, a computational biology professor at the University of California, Berkeley and the University of Copenhagen, whose study appears in the journal Nature. Our genome contains residual genetic fragments from other organisms like viruses as well as species like Neanderthals with which early modern humans interbred. The researchers called their study the first to show that a gene from an archaic human species has helped modern humans adjust to different living conditions. “Such exchange of genes with other species may in fact have helped humans adapt to new environments encountered as they spread out of Africa and into the rest of the world,” said  Nielsen. Asan Ciren, a researcher with China’s BGI genomics center, added, “The genetic relationship or blood relationship between modern humans and archaic hominins is a hot topic of the current paleoanthropology.”  The researchers said early modern humans trekking out of Africa interbred with Denisovans in Eurasia en route to China. Their descendants harbor a tiny percentage of Denisovan DNA. Genetic studies show nearly 90 percent of Tibetans have the high-altitude gene variant, along with a small percentage of Han Chinese, who share a common ancestor with Tibetans. It is seen in no other people. The researchers conducted genetic studies on 40 Tibetans and 40 Han Chinese and performed a statistical analysis showing that the gene variant almost certainly was inherited from the Denisovans. The gene regulates production of hemoglobin, a protein in red blood cells that carries oxygen. It is turned on when blood oxygen levels drop, stimulating more hemoglobin production. At elevations above 13,000 feet (4,000 meters), the common form of the gene boosts hemoglobin and red blood cell production, causing dangerous side effects. The Tibetans’ variant increases hemoglobin and red blood cell levels only modestly, sparing them these effects.

[Q]: The Portland Press Herald reports the Maine Center for Disease Control and Prevention recorded 1,310 Lyme disease cases through Dec. 27. That’s a 29 percent from 1,852 reported cases in 2017. Lyme disease is spread by ticks. Maine Medical Center Research Institute research associate Susan Elias says ticks are easily affected by changes in weather. Experts say hot, dry weather during the summer may have stressed tick populations. Researchers add that snow and colder weather in November probably deterred tick activity. According to biologist Chuck Lubelczyk, researchers are finding “much lower” numbers of ticks in field surveys. Lyme can cause flu-like conditions, neurological problems, joint paint and other symptoms. ___ Information from: Portland Press Herald, http://www.pressherald.com
