Rejected by a person you like? Just "shake it off" and move on, as music star Taylor Swift says. But while that might work for many people, it may not be so easy for those with untreated depression, a new brain study finds. The pain of social rejection lasts longer for them -- and their brain cells release less of a natural pain and stress-reducing chemical called natural opioids, researchers report in the journal Molecular Psychiatry.

How will we know if the economy has really gotten better, rather than using bogus claims about employment or how well Wall Street executives are doing? When senior citizens stop killing themselves.
Cancer data compiled by the World Health Organisation's (WHO) GLOBOCAN project has huge global influence and is used by Governments and international NGOs to determine health and funding priorities in sub-Saharan Africa.
We make hundreds, possibly thousands, of decisions each day without having full knowledge of what will happen next. Life is unpredictable, and we move forward the best we can despite not knowing every detail.
It's no different in the natural world. The Earth is warming, fish stocks and species counts fluctuate and we're experiencing more extreme weather. Conservation managers need to act quickly and make decisions about how to address these issues - even though questions remain.
World's challenges demand science changes - and fast, experts say.
The world has little use - and precious little time -- for detached experts.
A group of scientists - each of them experts - makes a compelling case in this week's Science Magazine that the growing global challenges has rendered sharply segregated expertise obsolete.
The use of animals in experimental research has soared at leading US laboratories in recent years, finds research published online in the Journal of Medical Ethics.
This is despite growing public opposition to animal experimentation, mounting evidence that animal studies often do not faithfully translate to people, and the development of new research technologies that supplant animal use.
The data contradict industry claims of reduced animal use and are at odds with government policies designed to curb and replace the use of animals in experiments, say the researchers.
Lord Ara Darzi and Oliver Keown at the Institute of Global Health Innovation want a ban to help smokers quit and to protect children from seeing people lighting up.
Extending anti-smoking legislation in the UK to encompass a ban in parks and squares "is an opportunity to celebrate the great beacon of healthy living, clean air, and physical activity our green spaces are designed for," they write. "And, crucially, it is an opportunity to support our population - young and old - to make healthier lifestyle choices easier."
Competition among doctors' offices, urgent care centers and retail medical clinics in wealthy areas of the U.S. often leads to an increase in the number of antibiotic prescriptions written per person, a team led by Johns Hopkins researchers has found.
"We found that both the number of physicians per capita and the number of clinics are significant drivers of antibiotic prescription rate," the researchers say in a report on the findings published online ahead of print in the Journal of Antimicrobial Chemotherapy.
Sub-Saharan Africans rate their own wellbeing, their health and their health-care systems among the lowest in the world, according to a new report published by Princeton University's Woodrow Wilson School of Public and International Affairs.
Despite these low ratings, health care is not a primary policy concern for people in these countries. Instead, sub-Saharan Africans cite jobs as a top priority, followed by improving agriculture and tackling corruption.
A new study reports a significant decline in the rate of cesarean section (C-section) births in Portugal. The findings indicate a 10% reduction in overall C-section rates between 2009 and 2014, with a 14% reduction in state-hospitals during the same time period. Researchers believe this may be due to more information and training of health care staff, along with inclusion of C-section rates as part of the criteria for hospital funding.
Changes in pension and employment policies are making it increasingly necessary for older people in the UK to work beyond the age of 65. However, new research from the University of Surrey finds significant differences in the likelihood of employment and income levels of people beyond 65, depending on their gender and health.
In the past decade, the H1N1 virus and Ebola are just two of the diseases whose spread was spurred by international airline travel. Screening passengers at airports, therefore, could be one key method for slowing the global spread of infectious diseases.
New research has found some teachers mark boys' primary (elementary) school maths tests more favourably than girls, impacting girls' uptake of advanced mathematics and science subjects in high school. Entrance rates into maths and science degrees at university level can also be traced back to the impacts of teachers' gender bias in primary school.
The push to boost food production in East Africa that is accelerating the conversion of natural lands into croplands may be significantly increasing the risk of plague according to a new study in the American Journal of Tropical Medicine and Hygiene.
A doctor's recommendation and a patient's race may influence flu vaccination rates, according to researchers at Henry Ford Hospital in Detroit. Researchers found that 90 percent of patients received vaccination if their physician advocated for it compared to 58 percent of patients whose physician did not.
Vaccination rates were also higher in whites (93 percent) and Asians (84 percent) than African Americans (62 percent), researchers say, theorizing that African Americans might not trust the vaccination's benefit.
