The people most often cited as "education experts" in blogs and news stories may have the backing of influential organizations - but have little background in education and education policy, a new study suggests.

Considerable debate surrounds the migration of human populations out of Africa. Two predominant hypotheses concerning the timing contrast in their emphasis on the role of the Arabian interior and its changing climate. In one scenario, human populations expanded rapidly from Africa to southern Asia via the coastlines of Arabia approx. 50,000 to 60,000 years ago. Another model suggests that dispersal into the Arabian interior began much earlier (approx.
In light of the current 18:1 sentencing disparity between crack and powder cocaine possession in the United States, researchers from New York University's Center for Drug Use and HIV Research examined socioeconomic correlates of use of each, and relations between use and arrest, to determine who may be at highest risk for arrest and imprisonment.
Over time, patients with advanced kidney disease have been starting dialysis progressively earlier in the course of their disease, likely because doctors are embracing higher levels of kidney function as being appropriate for dialysis initiation. The findings come from a study appearing in an upcoming issue of the Journal of the American Society of Nephrology (JASN).
Governor Tom Wolf today signed an executive order reinstating a moratorium on new leases for oil and gas development in state parks and forests. At an event in Benjamin Rush State Park, Governor Wolf signed the executive order with members of the General Assembly in attendance.
How can we keep more people from joining the ranks of the 29 million Americans already diagnosed with diabetes? What if we could tell with precision who has the highest risk of developing the disease, and figure out which preventive steps are most likely to help each of them individually?
Researchers have just released a "precision medicine" approach to diabetes prevention that could do just that - using existing information like blood sugar levels and waist-to-hip ratios, and without needing new genetic tests.
More than 1 in 4 females have experienced cyberbullying in college, increasing their risk for depression. Female college students who acted as cyberbullies were also more likely to report problem alcohol use, according to a new study published in Cyberpsychology, Behavior, and Social Networking.
Although there is insufficient evidence to draw firm conclusions about how the U.S. illicit tobacco market would respond to any new regulations that modify cigarettes--for example, by lowering nicotine content--limited evidence suggests that demand for illicit versions of conventional cigarettes would be modest, says a new congressionally mandated report from the National Research Council and Institute of Medicine.
That humans and the cities we build affect the ecosystem and even drive some evolutionary change in species' traits is already known. The signs are small but striking: Spiders in cities are getting bigger and salmon in rivers smaller; birds in urban areas are growing tamer and bolder, outcompeting their country cousins.
What's new is that these evolutionary changes are happening much more quickly than previously thought, and have potential impacts on ecosystem function on a contemporary scale. Not in the distant future, that is -- but now.
Gender and personality matter in how people cope with physical and mental illness, according to a paper by a Washington State University scientist and colleagues at the University of the Thai Chamber of Commerce.
Worldwide, consumption of healthy foods such as fruit and vegetables has improved during the past two decades, but has been outpaced by the increased intake of unhealthy foods including processed meat and sweetened drinks in most world regions, according to the first study to assess diet quality in 187 countries covering almost 4.5 billion adults, published in The Lancet Global Health journal.
Stress is a staple of our lives today, and we know intuitively that it can influence our confidence in competing with others. But how exactly does stress do that? Scientists at EPFL have carried out the first behavioral study to show how stress actually affects our degree of confidence, implying that it can even be a cause of social inequality rather than just a consequence of it. On a biological level, the researchers have also associated the effects of stress with the release of the hormone cortisol. The study is published in Psychoneuroendocrinology.
Companies are starting to embrace social media as a viable disclosure channel for product recalls, with the goal of limiting and repairing damage to the firms' reputation.
Using a sample of 405 consumer product recalls between 2000 and 2012, researchers found that corporate social media, in general, lessens negative price reactions to product recall announcements. However, as social media evolved from less to more interactive channels, firms have lost complete control over the content appearing on their corporate social media, and the benefits of social media have lessened.
Four minutes into the 1994 Oscars, host Whoopi Goldberg declared: “Tonight we gather to honour Hollywood’s best, which is also the world’s best”. The directors of the five films nominated for the Best Foreign Language category, including Taiwanese Ang Lee and the eventual winner from Spain Fernando Trueba, must have felt like getting their coats.
Maybe you should take a good look at your partner's fingers before putting a ring on one. Men with short index fingers and long ring fingers are on average nicer towards women, and this unexpected phenomenon stems from the hormones these men have been exposed to in their mother's womb, according to a new study by researchers at McGill University. The findings might help explain why these men tend to have more children. The study, showing a link between a biological event in fetal life and adult behaviour, was published in the journal Personality and Individual Differences.
