In 2012, scientists involved in the ENCODE (Encyclopedia of DNA Elements) project stated that 80% of our genome is functional - that it has some biochemical function. 

The finding was controversial, with critics arguing that the biochemical definition of 'function' was too broad - just because an activity on DNA occurs, it does not necessarily have a consequence. For functionality, you need to demonstrate that an activity matters. 

Fragile X syndrome (FXS) is a genetic disorder that causes obsessive-compulsive and repetitive behaviors, and other behaviors on the autistic spectrum, as well as cognitive deficits. It is the most common inherited cause of mental impairment and linked to autism.

Researchers have published a study that sheds light on the cause of autistic behaviors in FXS. The study describes how MMP-9, an enzyme, plays a critical role in the development of autistic behaviors and synapse irregularities, with potential implications for other autistic spectrum disorders.

Vouchers to buy fresh fruits and vegetables at farmers markets increase the amount of produce in the diets of some families on welfare, according to a new paper in research in Food Policy which suggests that farmers market vouchers can be useful tools in improving access to healthy food.  Perhaps. Half of the people dropped out of the test even though they got more money to shop for produce at farmer's markets.

The analysis was designed to validates a new provision in the Agricultural Act of 2014 that seeks to get low-income families buying produce at farmers markets rather than supermarkets.

Pharmaceutical companies are in a tough position; they are highly regulated, trials are expensive, new products fail most of the time, and if they are successful, everyone complains the cost is too high while the company tries to make money before it goes generic.

In the UK, the company with the best antibiotic pipeline in the world, AstraZeneca, is trying to sell that business, because they don't think they will ever make money at it given current restrictions.

A new paper by the Physics Teacher Education Coalition (PhysTEC) has identified two factors that characterize sustainable university and college programs designed to increase the production of highly qualified physics teachers. Specifically, one or more faculty members who choose to champion physics teacher education in combination with institutional motivation and commitment can ensure that such initiatives remain viable. Science, Technology, Engineering and Math (STEM) teacher shortages are especially acute in physics, and the study points the way for institutions seeking to increase the number of STEM graduates prepared to teach. 

A sake brewery has its own microbial terroir, meaning the microbial populations found on surfaces in the facility resemble those found in the product and help create the final flavor. This is the first time investigators have taken a microbial census of a sake brewery. 

Many sake makers inoculate with both bacteria and yeast, says corresponding author David A. Mills of the University of California, Davis, but he and his colleagues investigated a sake brewery where inoculation is restricted to a single species, Aspergillus oryzae, at the first of three stages of fermentation.

Female triathletes are at risk for pelvic floor disorders, decreased energy, menstrual irregularities and abnormal bone density, according to researchers at Loyola University Health System (LUHS). These data were presented at the American Urogynecologic Society 2014 Scientific Meeting in Washington, DC.

The study found that one in three female triathletes suffers from a pelvic floor disorder such as urinary incontinence, bowel incontinence and pelvic organ prolapse. One in four had one component of the female athlete triad, a condition characterized by decreased energy, menstrual irregularities and abnormal bone density from excessive exercise and inadequate nutrition.

A new study suggests that Saharan dust played a major role in the formation of the Bahamas islands. Researchers from the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science showed that iron-rich Saharan dust provides the nutrients necessary for specialized bacteria to produce the island chain's carbonate-based foundation.

A newly discovered gut virus, crAssphage, probably isn't new at all, it was just discovered. But it's in half the world's population, according to estimates. 

A new paper in Nature Communications says crAssphage infects one of the most common types of gut bacteria, Bacteroidetes. This phylum of bacteria is thought to be connected with obesity, diabetes and other gut-related diseases. 

Robert A. Edwards, a bioinformatics professor at San Diego State University, and colleagues stumbled upon the discovery while using results from previous studies on gut-inhabiting viruses to screen for new viruses.

In Aesop's fable about the crow and the pitcher, a thirsty bird happens upon a vessel of water, but when he tries to drink from it, he finds the water level out of his reach. Not strong enough to knock over the pitcher, the bird drops pebbles into it — one at a time — until the water level rises enough for him to drink his fill.

Highlighting the value of ingenuity, the fable demonstrates that cognitive ability can often be more effective than brute force. It also characterizes crows as pretty resourceful problem solvers. New research conducted by UC Santa Barbara's Corina Logan, with her collaborators at the University of Auckland in New Zealand, proves the birds' intellectual prowess may be more fact than fiction.
