With human rights violations by government police forces on the increase, it might seem like a bad time for cops to decide who gets a gun to defend themselves but Massachusetts police chiefs say it should be not be an equal right for all people legally allowed, it should remain up to the police.

Literacy has been getting declining support in recent years. The Obama administration only wants to spend $187 million for its Effective Teaching and Learning: Literacy initiative while the Bush administration devoted $1 billion annually to the Reading First program. That means it is necessary to find out which programs work best. A new study uses a scientific lens to look at the conversational art of instruction, a team of researchers identify specific ways teachers talk to students that measurably impact literacy skills.

A global study on canine rabies has found that 160 people die every single day from the disease. The report is the first study to consider the impact in terms of deaths and the economic costs of rabies across all countries. Even though the disease is preventable, the study says that around 59,000 people die every year of rabies transmitted by dogs.

With poor sanitation estimated to cause 280,000 deaths per year worldwide, improving sanitation is a key policy goal in many developing countries. Yet governments and major development institutions disagree over how to address the problem. A new study released in Science today found that in Bangladesh, a community-motivation model that has been used in over 60 countries to increase use of hygienic latrines had no effect, yet latrine coverage expands substantially when that model is combined with subsidies for hygienic latrines targeted to the poor.

A national survey suggests that slightly more than half of the older adults in the United States are now taking a daily dose of aspirin, even though its use is not recommended by the Food and Drug Administration for most people who have not yet had a heart attack or stroke.

The analysis was published today in the American Journal of Preventive Medicine. It observed that aspirin use is continuing to surge, especially among adults who are using it for "primary prevention," meaning in order to prevent an initial cardiovascular event, and in some cases to prevent cancer.

If you are looking to raise money online for your favorite cause, listen up. A real-world analysis of human behavior reported in the Cell Press journal Current Biology on April 16 shows that men treat online giving as a competitive enterprise. Men will donate four times more money to an attractive female fundraiser in response to the contribution of another male.

Researchers say that they suspect this tendency is a subconscious part of human psychology that exists because it is (or was) evolutionarily beneficial to us.

Over 2001-2011, the national incidence of firearm-related hospitalizations has closely tracked the national stock market performance, suggesting that economic perturbations and resultant insecurities might underlie the perpetuation of firearm-related injuries, according to a new study published in The American Journal of Medicine. Although the fatality rates have remained stable over the last two decades, the average length of stay and hospitalization costs have increased, imposing additional burden on existing healthcare resources.

Faced with requests to meet with potential doctoral students of easily identifiable gender, race or ethnicity, faculty in almost every academic discipline are significantly more responsive to white males than to women and minorities, according to research published by the American Psychological Association.

And faculty in higher-paid disciplines, such as business, engineering/computer science and the life sciences, and those at private universities, show more of this bias than their counterparts in lower-paying disciplines and public universities, the study found.

There is concern about e-cigarettes that they may cause addiction rather than cure it - California advocates are spending millions claiming Big Tobacco is marketing them to children - but like nicotine patches and chewing gum, teens may try them but unless they already smoke, they don't embrace them.

Cancer mortality remains significantly elevated among African Americans. Between 2000 and 2010, overall mortality from cancer decreased faster among African American women and men than among Caucasians. If current trends continue, racial disparities in cancer outcomes are expected to narrow further and might disappear over time.

Teachers are likely to interpret students' misbehavior differently depending on the student's race, according to new research findings published in Psychological Science, a journal of the Association for Psychological Science.

Racial differences in school discipline are widely known, and black students across the United States are more than three times as likely as their white peers to be suspended or expelled, according to Stanford researchers.

Yet the psychological processes that contribute to those differences have not been clear -- until now.

Invasive pests known as spruce bark beetles have been attacking Alaskan forests for decades, killing more than 1 million acres of forest on the Kenai Peninsula in southern Alaska for more than 25 years. Beyond environmental concerns regarding the millions of dead trees, or "beetle kill" trees, inhabitants of the peninsula and surrounding areas are faced with problems including dangerous falling trees, high wildfire risks, loss of scenic views and increased soil erosion.

A healthy and active old age is a reality for many Europeans and is a genuine possibility for many more, despite the 2008 economic crash and years of austerity measures, according to a new United Nations Economic Commission for Europe (UNECE) and European Commission (EC) report, produced at the University of Southampton.

However, countries such as Greece and Latvia have declined in active ageing capacity during the four years from 2008 to 2012.

Young offenders in late Victorian times were much less likely to go on to commit other crimes after serving a sentence in an institution than their counterparts today, new research shows.

A study of the lives of 500 children committed to reformatory or industrial schools over a century ago showed that only 22% re-offended during the rest of their lives after their release. This compares with today's figure of 73% of young people re-offending within a year after release from custody.

A survey of California doctors found that a majority of the 525 who responded believe the Patient Protection and Affordable Care Act (ACA, nee Obamacare) will steer the country's health care in the right direction.
