Frequent travel is damaging to health and wellbeing, according to new study
Researchers investigated how frequent, long-distance travel is represented in mass and social media. They found that the images portrayed do not take into account the damaging side effects of frequent travel such as jet-lag, deep vein thrombosis, radiation exposure, stress, loneliness and distance from community and family networks.

Marriage can lead to dramatic reduction in heavy drinking in young adults
Research on alcohol-use disorders consistently shows problem drinking decreases as we age. Now, researchers have found evidence that marriage can cause dramatic drinking reductions even among people with severe drinking problems. Scientists believe findings could help improve clinical efforts to help these people, inform public health policy changes and lead to more targeted interventions for young adult problem drinkers.

Our elegant brain: Motor learning in the fast lane
To learn new motor skills, neurons within the cerebellum engage in elegant, virtually mathematical, computations to quickly compare expected and actual sensory feedback. They then quickly readjust, changing the strength of connections between other neurons to form new patterns in the brain in order to accomplish the task at hand, researchers report.

Lab experiment mimics early-stage planetary formation process
Physicists have directly observed, for the first time, how highly charged dust-sized particles attract and capture others to build up clusters particle by particle. This process can lead to the formation of "granular molecules" whose configurations resemble those of simple chemical molecules.

Body size increase did not play a role in the origins of homo genus, new analysis suggests
A new analysis of early hominin body size evolution suggests that the earliest members of the Homo genus (which includes our species, Homo sapiens) may not have been larger than earlier hominin species.

What would the world look like to someone with a bionic eye?
While major advancements have been made in vision recovery technologies, the vision provided by those devices might be very different from what scientists and patients have assumed.

Quantum states in a nano-object manipulated using a mechanical system
Scientists have used resonators made from single-crystalline diamonds to develop a novel device in which a quantum system is integrated into a mechanical oscillating system. For the first time, the researchers were able to show that this mechanical system can be used to coherently manipulate an electron spin embedded in the resonator -- without external antennas or complex microelectronic structures.

The uneasy, unbreakable link of money and medicine
After centuries of concerns about the potentially compromising role of money in medicine, the debate remains irreconcilable and the link remains indivisible, a new article suggets. Even the reforms of Obamacare, the author writes, may not change much.

Shifting winds, ocean currents doubled endangered Galápagos penguin population
Shifting winds, ocean currents doubled endangered Galápagos penguin population, new research shows. The Galápagos Islands, a chain of islands 1,000 kilometers (600 miles) west of mainland Ecuador, are home to the only penguins in the Northern Hemisphere. The 48-centimeter (19-inch) tall black and white Galápagos penguins landed on the endangered species list in 2000 after the population plummeted to only a few hundred individuals and are now considered the rarest penguins in the world.
