People with depression or bipolar disorder often feel their thinking ability has gotten "fuzzy", or less sharp than before their symptoms began, and a new study published in BRAIN finds that the effect is real - and rooted in brain activity differences that show up on advanced brain scans. 

According to a new paper, there is more than meets the eye when it comes to the impact of Saturday morning cartoons, in particular the popular 1980s cartoon series "The Transformers", and what it did to shape children's perceptions of what behaviors are associated with effective leadership.

"The Transformers" started in 1984 with a toy line of transforming factions of alien robots fighting a civil war that spread to Earth -- the "good" Autobots, seeking peace, and the "bad" Decepticons, vying for galactic domination. The franchise has grown to include animation, comic books, video games and films, grossing more than $1 billion, whereas their competitors at the time, the Go-Bots, have been left behind.

Ethanol fuel refineries could be releasing much larger amounts of some ozone-forming compounds into the atmosphere than previous estimates. 

Ethanol, a government mandated and subsidized renewable transportation fuel made from corn, now constitutes approximately 10 percent of the fuel used in gasoline vehicles in the U.S., according to the new study. The renewable fuel mandate was a successful environmental effort to increase the use of ethanol and other renewable fuels aims to reduce greenhouse gas emissions and petroleum imports, while encouraging development and expansion of the U.S. renewable fuels sector, according to the U.S. Environmental Protection Agency.

Researchers have succeeded in reconstructing the neuronal networks that interconnect the elementary units of sensory cortex, called cortical columns. A key challenge in neuroscience research is identifying organizational principles of how the brain integrates sensory information from its environment to generate behavior. One of the major determinants of these principles is the structural organization of the highly complex, interconnected networks of neurons in the brain.

To help, researchers constructed anatomically-realistic 3D models of such neuronal networks in the rodent brain. 

Mutations in two genes cause a fatal lung scarring disease known as familial pulmonary fibrosis and can cause excessive shortening of the ends of chromosomes, known as telomeres. Telomeres are repetitive sequences of DNA that protect the ends of chromosomes from deteriorating. Think of them like the plastic ends of shoelaces, which protect shoelaces from fraying. 

As the realities of legalized marijuana take hold in four states and the District of Columbia, legislators and regulators could learn a lot from the successes (and failures) of the tobacco and alcohol industries in keeping their harmful products out of the hands of children and adolescents.
