Intriguing new study on the optimal amount of sleep. But that grain of salt can’t be overstated given the wide variation of “chronotypes” and internal time.

People with bachelor’s degrees in science, technology, engineering and math are more likely than other college graduates to have a job, but most of them don’t work in STEM occupations, according to a U.S. Census Bureau report released Thursday.
Nearly 75 percent of all holders of bachelor’s degrees in STEM disciplines don’t have jobs in STEM occupations, according to a survey that reached 3.5 million homes, said Liana Christin Landivar, a sociologist with the Census Bureau. The bureau’s American Community Survey is the largest household survey in the nation.
About half of those who have degrees related to engineering, computers, math and statistics do get a STEM job, the survey found.
A new study suggests posting sexy or revealing photos by girls and young women on social media sites gives their female peers a bad impression.
“There is so much pressure on teen girls and young women to portray themselves as sexy, but sharing those sexy photos online may have more negative consequences than positive,” Daniels said.
A new experimental study analyzed how cooperative attitudes evolve in different age ranges. Researchers found that young people between the ages of ten and sixteen demonstrate more fickle behavior when it comes to cooperating, unlike other age groups. People over the age of 66 demonstrated the most cooperative behavior.
Children learn quite a bit from their older siblings, according to new research from Concordia University. These teaching moments, initiated by both the older and younger siblings, tend to occur naturally and also incorporate a variety of instructional techniques.
MIT Finger Device Reads to the Blind in Real Time
“Scientists at the Massachusetts Institute of Technology are developing an audio reading device to be worn on the index finger of people whose vision is impaired, giving them affordable and immediate access to printed words.
The so-called FingerReader, a prototype produced by a 3-D printer, fits like a ring on the user’s finger, equipped with a small camera that scans text. A synthesized voice reads words aloud, quickly translating books, restaurant menus and other needed materials for daily living, especially away from home or office.”

The deeper problem is that citizens participate in public life precisely because they believe the issues at stake relate to their values and ideals, especially when political parties and other identity-based groups get involved – an outcome that is inevitable on high-profile issues. Those groups can help to mobilize the public and represent their interests, but they also help to produce the factual divisions that are one of the most toxic byproducts of our polarized era. Unfortunately, knowing what scientists think is ultimately no substitute for actually believing it.
Under heavy pressure to excel, significant numbers of European university students are using cognitive enhancers, so-called smart drugs, to keep up with academic demands, recent studies show.
A lack of long-term research makes it difficult to gauge whether the use of such stimulants, with the aim of improving concentration and memory, is on the rise — and if so, to what degree — says Boris Quednow, an assistant professor and psychologist at the Psychiatric Hospital of the University of Zurich.
Substances used, the study found, included alcohol, the most commonly reported, by 5.6 percent of respondents; methylphenidate — sold under several trade names, including Ritalin — reported by 4.1 percent; sedatives (2.7 percent); beta blockers (1.2 percent); cannabis (2.5 percent); amphetamines (0.4 percent), and cocaine (0.2 percent).

A new study finds that while managers have a negative view of employee use of social media for private purposes during work, top executives frequently surf the web during work hours.
“It is very interesting that top executives, who are negative to private web-surfing during working hours, are the ones who surf the most for private purposes when at work,” said postdoctoral fellow Cecilie Schou Andreassen, Ph.D.
Michael Anderson of Yale’s Peabody Museum and Natural History and Ken Lovell of Yale’s Digital Media Center for the Arts are researching 3D printing techniques for maintaining and restoring the Peabody’s unique natural history dioramas.

In the new study, psychological scientist Brooke Macnamara, Ph.D., of Princeton University, and colleagues offer a dissenting view, suggesting that the amount of practice accumulated over time does not seem to play a huge role in accounting for individual differences in skill or performance.

Researchers have found strong evidence that attaining a higher level of education and spending more years in school are two factors associated with a greater prevalence and severity of nearsightedness, or myopia. The research is the first population-based study to demonstrate that environmental factors may outweigh genetics in the development of myopia.
- 24 percent with no high school education or other training were nearsighted
- 35 percent of high school graduates and vocational school graduates were nearsighted
- 53 percent of university graduates were nearsighted
Unscheduled, unsupervised, playtime is one of the most valuable educational opportunities we give our children. It is fertile ground; the place where children strengthen social bonds, build emotional maturity, develop cognitive skills, and shore up their physical health. The value of free play, daydreaming, risk-taking, and independent discovery have been much in the news this year, and a new study by psychologists at the University of Colorado reveals just how important these activities are in the development of children’s executive functioning.
