Link 23 Apr Lifestyle determines gut microbes: Study with modern hunter-gatherers tells tale of bacteria co-evolution -- ScienceDaily»

The intestinal bacteria of present-day hunter-gatherers has for the first time been deciphered by an international team of researchers. Bacterial populations have co-evolved with humans over millions of years, and have the potential to help us adapt to new environments and foods. Studies of the Hadza offer an especially rare opportunity for scientists to learn how humans survive by hunting and gathering, in the same environment and using similar foods as our ancestors did.

If an insect drew a line as it chased its next meal, the resulting pattern would be a tangled mess. But there’s method to that mess: It turns out the tiger beetle, known for its speed and agility, does an optimal reorientation dance as it chases its prey at blinding speeds.

It’s a hard pill to swallow, but if you’re over 24 years of age you’ve already reached your peak in terms of your cognitive motor performance, according to a new study. In one of the first social science experiments to rest on big data, the researchers investigate when we start to experience an age-related decline in our cognitive motor skills and how we compensate for that.

Link 22 Apr Hair from infants gives clues about life in womb -- ScienceDaily»

Like rings of a tree, hair can reveal a lot of information about the past. And, as a team of researchers show in a study of rhesus monkeys, it can also reveal the womb environment in which an infant formed. It’s the first time researchers have used infant hair to examine the hormonal environment to which the fetus was exposed during development and it promises to yield a wealth of new information. The findings have significant implications for several fields, from neonatology to psychology, social science to neurology.

Researchers have identified head circumference and head tilting reflex as two reliable biomarkers in the identification of autism spectrum disorders (ASD) in children that are between 9 and 12 months of age. ASD is identifiable as early as two years old, although most children are not identified until after the age of four. While a number of studies have reported that parents of children with ASD notice developmental problems in children before their first birthday, there has yet to be a screening tool to identify those children.

In a study of nearly 1,000 mother-child pairs, researchers found that prenatal exposure to selective serotonin reuptake inhibitors (SSRIs), a frequently prescribed treatment for depression, anxiety and other disorders, was associated with autism spectrum disorder and developmental delays in boys.

Link 21 Apr Decades-old mystery solved of how cells keep from bursting»

A team led by scientists has identified a long-sought protein that facilitates one of the most basic functions of cells: regulating their volume to keep from swelling excessively. The identification of the protein, dubbed SWELL1, solves a decades-long mystery of cell biology and points to further discoveries about its roles in health and disease — including a serious immune deficiency that appears to result from its improper function.
