Why are Generic Drugs Getting Pricy?

January 22, 2015 7:00 am | by The Conversation, Geoffrey Joyce | News | Comments

More than eight out of every 10 prescriptions dispensed in the U.S. is generic. This growth is because of a large number of top-selling drugs going off patent over the past decade, as well as innovations in the retail sector. But, recently, prices of some long-time generic drugs like digoxin (a heart medication), albuterol (for asthma) and doxycycline (an antibiotic) increased more than 10-fold over a very short period of time.

More Realistic Exercise Targets Needed

January 22, 2015 7:00 am | by British Medical Journal | News | Comments

Current guidelines suggest adults do 150 minutes of moderate intensity activity a week, but more than a third of adults worldwide are sufficiently inactive. Two articles this week argue that the 150 minute target is beyond the reach of some, especially older people, and say we should be promoting the benefits of small increases in daily physical activity.

Lasers Make Metal Surfaces Extremely Water-repellent

January 22, 2015 7:00 am | by Univ. of Rochester | Videos | Comments

Scientists have used lasers to transform metals into extremely water repellent, or super-hydrophobic, materials without the need for temporary coatings. Super-hydrophobic materials are desirable for a number of applications such as rust prevention, anti-icing or even in sanitation uses. However, most current hydrophobic materials rely on chemical coatings.

Trick Cripples Wild Bacteria

January 21, 2015 3:00 pm | by Associated Press, Malcolm Ritter | News | Comments

Bacteria have been modified so that they die if they get out of human control, a potential step toward better management of genetically engineered organisms— perhaps including crops, researchers say. The new technique might reduce the risk of using genetically altered microbes outdoors, such as for cleaning up toxic spills.

The government is pushing the poultry industry to make their chicken and turkey a little safer with new standards aimed at reducing the number of cases of foodborne illness by 50,000 a year. The proposed standards announced today apply to the most popular poultry products— chicken breasts, legs and wings, and ground chicken and turkey.

Young lovers walking down the aisle may dream of long and healthy lives together, but close friends in the wedding party may have a better sense of whether those wishes will come true, suggests new research on personality and longevity. Your friends see you in a positive manner, but they also are keen observers of the personality traits that could send you to an early grave.

Genders Process Emotions Differently

January 21, 2015 3:00 pm | by Univ. of Basel | News | Comments

Women rate emotional images as more emotionally stimulating than men do and are more likely to remember them. However, there are no gender-related differences in emotional appraisal as far as neutral images are concerned, according to a large-scale study that focused on determining the gender-dependent relationship between emotions, memory performance and brain activity.

Turing's Notebook to Be Auctioned

January 21, 2015 3:00 pm | by Associated Press | News | Comments

A handwritten notebook by Alan Turing, the World War II code-breaking genius, is going on the auction block. The 56-page manuscript was written at the time the British mathematician and computer science pioneer was working to break the seemingly unbreakable Enigma codes used by the Germans throughout World War II. It is expected to bring at least $1 million.

Baby’s Hunger Hormone Linked to Continued Obesity

January 21, 2015 3:00 pm | by The Saban Research Institute of Children’s Hospital Los Angeles | News | Comments

Our subconscious motivation to eat is powerfully and dynamically regulated by hormone signals. The gut-derived hormone ghrelin is one such key regulator. Now, researchers have revealed an unexpected role for ghrelin in early brain development and show its long-term impact on appetite regulation.

Study Finds Fight or Flight Response Control Center

January 21, 2015 7:00 am | by Johns Hopkins Univ. | News | Comments

An animal study has uncovered what controls the ability of healthy hearts to speed up in response to circumstances ranging from fear to a jog around the block. The key to the heart’s “fight or flight” response, researchers report, is a channel in cells’ energy factories. Better understanding of this channel could lead to new treatments for people whose heart rates needlessly accelerate.

Ocean's Dust Sheds Light on Supernovae

January 21, 2015 7:00 am | by Australian National Univ. | News | Comments

Scientists plumbing the depths of the ocean have made a surprise finding that could change the way we understand supernovae, exploding stars way beyond our solar system. The researchers have analyzed extraterrestrial dust, thought to be from supernovae, that has settled on ocean floors to determine the amount of heavy elements created by the massive explosions.

Self-regulation, Not Facebook, to Blame for Low Grades

January 21, 2015 7:00 am | by Iowa State Univ. | News | Comments

It may not come as a surprise that the more time college students, particularly freshmen, spend on Facebook, the more their grades suffer. In a study, an associate professor found that, while freshman struggle to balance their use, social media is less of a problem for upper classmen. The difference relates to self-regulation.

Cancer-causing Agent in Water After Oil Spill

January 21, 2015 7:00 am | by Associated Press, Matthew Brown | News | Comments

A cancer-causing component of oil has been detected in the drinking water supply of an eastern Montana city just downstream from a crude oil spill that entered the Yellowstone River. Elevated levels of benzene were found in water samples taken from a treatment plant that serves about 6,000 people in the agricultural community of Glendive near the North Dakota border, officials said.
