Two new seismic source technologies developed for safer and less costly deep-ocean exploration
The U.S. Department of Energy's Idaho National Engineering and Environmental Laboratory and the University of Arkansas have developed two technologies that may ultimately enable safer and more economical oil and gas deep-ocean exploration.

Study clarifies brain mechanisms of cocaine's high
A team of researchers led by scientists from NIDA has made a major advance in understanding the molecular basis of how cocaine produces its characteristic high, suggesting new targets for developing anti-addiction medications.

Greenhouse gases main reason for quicker northern winter warming
Greenhouse gases are the main reason why the northern hemisphere is warming quicker during winter-time months than the rest of the world, according to new computer climate model results by NASA scientists.

New proteomics tool offers a clear look at cellular proteins IDAT can detect proteins at an unprecedented resolution for research and clinical use
Researchers at the University of Pennsylvania School of Medicine have created IDAT, the first new technology for the proteomic era, a technique sensitive enough to detect individual proteins and robust enough to potentially screen hundreds or thousands of molecules in mass automation.

Mom's warmth influences kid's ability to get along with others
A Penn State study has shown that elementary school children who have depressed mothers may have trouble regulating their emotions and getting along with other kids because their moms are unable to show them enough warmth and sensitivity.

Countering the body's own harmful response to stroke
Scientists have found that a compound that recently made headlines for its potential in treating sepsis also holds promise in protecting brain cells from the damage caused by stroke.

New research confirms that natural selection is acting on the current human population

Fast medication adjustment, team approach yields lasting hypertension control
Using a physician/nurse team to rapidly adjust blood pressure drug dosage can significantly improve hypertension control rates and potentially reduce costs, according to a Mayo Clinic study published in the April issue of the American Journal of Hypertension.

IU School of Nursing studies find colorectal cancer screenings closely related to doctor recommendation
Two studies conducted at the IU School of Nursing found that one of the top reasons people do not get screened for colorectal cancer is because their physician did not recommend it.

New studies examine influences on adolescent depression: mother's depression and smoking can worsen symptoms and impair social functioning
Two factors relatively common in adolescence, smoking cigarettes and having a mother who suffers from depression, both increase the adolescent's own susceptibility to depression, according to two new studies in this month's Journal of Consulting and Clinical Psychology, published by the American Psychological Association (APA).

Moms discuss safer sex - not only abstinence -- with adolescent kids
Mothers don't find it easy to talk to their adolescent kids about responsible sexuality and AIDS but, when they do broach those subjects, a Penn State study has found that they are apt to talk about safer sex, too, if they bring up abstinence.

Researchers prove past cooling trend caused by move from forests to agriculture
Researchers in Lawrence Lab's Atmospheric Science Division have demonstrated a cooling of up to 2-degree Fahrenheit over land between 1000 and 1900 AD as a result of changes from natural vegetation, such as forests, to agriculture. is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to
