Feeling unloved? Like this post on Facebook

Insecure? Craving attention and needing to feel good about yourself? Chances are Facebook is your friend.

A new study suggests that people who are generally insecure in their relationships are more actively engaged on the social media site - frequently posting on walls, commenting, updating their status or "liking" something - in hopes of getting attention.

In two surveys of nearly 600 people ages 18-83, researchers at Union College asked participants about their tendencies in close relationships and their Facebook habits.

What's next in diets? Chili peppers

Don't go chomping on a handful of chili peppers just yet, but there may be help for hopeful dieters in those fiery little Native American fruits.

Consumer preferences and the power of scarcity

When something is rare, it's alluring--true whether you're talking about precious gemstones or a pristine edition of the first issue of Action Comics (which introduced Superman). And psychologists have long known that if you can make a consumer good more desirable by making it appear rare.

Scandals not bad for business - in the long term

Jack-in-the-Box hamburgers once had a terrible reputation for quality and foodborne illnesses. The chairman of the BP oil company once whined that he wanted his life back after his company gushed oil across the Gulf of Mexico. Yet both companies are doing fine now.

Though the old staple in business is that 'it takes 5 years of work to win a customer back if you lose them due to quality or service', and that remains true, scandals involving bosses of major firms don't have long-term negative impact on share prices. They can even lead to better performance.

Ebola: Modeling a deadly epidemic

On Dec. 26, 2013, a two-year-old boy living in the Guinean village of Meliandou, Guéckédou Prefecture was stricken with a rare disease, caused by the filament-shaped Ebola virus.

The child is believed to be the first case in what soon became a flood-tide of contagion, ravaging the West African countries of Guinea, Sierra Leone and Liberia, infecting, according to the World Health Organization, over 21,000 cases as of Jan. 21, with nearly 9000 confirmed deaths--the actual toll likely much higher.

In evolution, settling for 'Mr. Right Now' is smarter than waiting for 'Mr. Right'

"Primitive humans were likely forced to bet on whether or not they could find a better mate," said Chris Adami, MSU professor of microbiology and molecular genetics and co-author of the paper.

"They could either choose to mate with the first, potentially inferior, companion and risk inferior offspring, or they could wait for Mr. or Ms. Perfect to come around," he said. "If they chose to wait, they risk never mating."

In Illinois, girls in STEM are being left behind

Illinois girls are only half as interested in Science, Technology, Engineering and Math (STEM) fields despite spending efforts to encourage participation.

Increasing individualism linked with rise of white-collar jobs

Rising individualism in the United States over the last 150 years is mainly associated with a societal shift toward more white-collar occupations, according to new research published in Psychological Science, a journal of the Association for Psychological Science.

College-educated cops are less satisfied with their jobs

A new study suggests college-educated cops are dissatisfied with the job, have negative views of their supervisors and don't necessarily favor community policing, a strategy aimed partly at reducing the number of deadly police-citizen incidents dominating the headlines.

But William Terrill, a Michigan State University criminologist and co-author of the study on police attitudes, said the findings tell only part of the story. In past research on police behavior, Terrill found college-educated officers are less likely to use force on citizens.

Internet comments influence opinions on vaccinations more than public service announcements

Anti-vaccine beliefs are going bipartisan, what was once the province of kooky progressives in California and Oregon is now also being embraced by American libertarians, and public service announcements are unlikely to help. Washington State University researchers say that people may be influenced more by online comments than by credible PSAs.

Expensive emergency care is better

Because Americans spend more per capita on health care than residents of any country, debate has rumbled on for years about whether all that investment yields sufficient results. Now a newly published study with a distinctive design, led by an MIT health care scholar, shows that increased spending on emergency care does, in fact, produce better outcomes for patients.

Why do poor kids in China have better vision than middle-class ones?

SAN FRANCISCO - Feb. 5, 2014 - In one of the largest population-based studies ever conducted on nearsightedness in children, researchers have discovered that lower-income students in China have better vision than their middle-class counterparts. Data show that nearsightedness, also called myopia, is twice as prevalent in the middle-income province of Shaanxi compared to the poorer neighboring province of Gansu. The study was published online today in Ophthalmology, the journal of the American Academy of Ophthalmology.

Plasma collection could outpace overall blood collection by 2018

Kalorama Information expects the market for plasma collection to grow, and to outpace overall blood collection through 2018. The primary market driver will be plasma-derived immunoglobulins (Ig) used to produce intravenous immunoglobulin (IVIG) therapies. The growth of mature markets associated with the collection, processing and therapeutic use of whole blood and derived products are by and large endangered without the robustness of the global plasma market.

Since paramedics are probably first line of treatment for stroke, let them give drugs?

There is no time to waste when it comes to stroke. The more time that passes between stroke onset and treatment, the worse the outcome is for the patient. A study designed to test the benefits of early administration of magnesium sulfate suggests that stroke patients may not have to wait until they get to the hospital for treatment -- paramedics may be able to start therapy as soon as stroke is suspected. Although the drug did not improve outcome in stroke patients, the study demonstrated the feasibility of early therapy in the ambulance.

Muslim women in Canada have more equality than in Muslim countries

A landmark study on gender equality among religious minorities in Canada sharply disputes the stereotype Muslim women are more repressed by men than other groups of immigrants.

Sharia law, burqas, honour killings and overseas terrorism directed at girls and women grab headlines and shape public opinion, but workforce participation rates among immigrants suggests a trend toward high levels of equality for Muslim females living in Canada.
