Taxonomy is an important aspect of microbiome research. Whether we are studying communities of bacteria, viruses, or other microbes, there are benefits to labeling microbes. Taxonomic names immediately give us information about their relationships to each other, such as similar bacteria being grouped into the same genus...... Read more »

Today I'm directing your reading attention to a really, really interesting paper by Lynn Waterhouse and colleagues  (open-access) whose review findings suggest that: "the ASD [autism spectrum disorder] diagnosis lacks biological and construct validity."The paper is a bit of a long read but most definitely worth it as the quite complicated subject of exactly what goal the label of autism actually serves is discussed. The results of various questions posed by the authors suggest: "No ........ Read more »
The most complex piece of matter in the known universe is the brain. Neuroscientists have recently taken on the challenge to understand brain function from its intricate anatomy and structure. There is no sure way to go about it, and researchers in Madrid proposed a solution to the problem.

An unusual study reports the effects of emoticons on human brain activity: Neural correlates of text-based emoticons
South Korean neuroscientists Ko Woon Kim et al. used fMRI to record brain activation in 18 volunteers who were shown various expressive text symbols, in both the Asian 'vertical' and Western 'horizontal' styles:
However, it turned out that the brain doesn't really respond to emoticons at all: there was no significant difference in the brain response to the real emoticons... Read more »

"Higher AQ [Autism Spectrum Quotient] scores were associated with higher scores of loneliness, social anxiety, depression, and anxiety, as well as with lower scores of quality of life (QoL)."Those were some of the key findings reported by Phil Reed and colleagues  who used the very popular 'are you autistic?'

"I don't know what you're talking about," said the polar bear. "Everything seems normal to me! Watch out for that puddle."
Up in the Arctic, things are getting slushy. But some polar bears are refusing to change their ways. Instead of compromising on where they spend their time, they're clinging to the icy habitats they've always loved. As those habitats keep shrinking, though, the bears will eventually find things too crowded and uncomfortable to ignore.
Researchers divide polar bear... Read more »

Physical activity can help reduce cardiovascular disease and premature mortality in people with psychological problems. However, there is limited data on exercise in people with serious mental disorders, especially from low- and middle-income countries. This study explored whether complying with the World Health Organization recommendations of 150 minutes of moderate-vigorous exercise per week is related to psychotic symptoms or the diagnosis of a psychosis.

Why do some people want to live a very long time, while others would prefer to die relatively young? In a latest study, a team of researchers investigated how long young and middle-aged adults in the United States say they want to live in relation to a number of personal characteristics. The results showed that more than one out of six people would prefer to die younger than age 80, before reaching average life expectancy.

Aneuploidy is the leading cause of miscarriage, stillbirth, and congenital birth defects and occurs as a result of errors during meiotic or mitotic cell division.1 As a woman ages, the probability of an aneuploid conception significantly rises, to roughly 50% by the age of 40.2 Only a fraction of full aneuploidies, primarily trisomies, will develop past the first trimester. This is in contrast to monosomies that almost never implant or result in an ongoing pregnancy. DNA methylation is an epi........ Read more »
