CRITICAL TURNING POINT CAN TRIGGER ABRUPT CLIMATE CHANGE, April 20
Ice ages are the greatest natural climate changes in recent geological times. Their rise and fall are caused by slight changes in the Earth's orbit around the Sun due to the influence of the other p***ts. But we do not know the exact relationship between the changes in the Earth's orbit and the changes in climate. New research from the Niels Bohr Institute indicates that there can be changes in the CO2 levels in the atmosphere that suddenly reach a critical turning point and with that trigger the dramatic climate changes. The results are published in the American journal Paleoceanography.

If this is the case, why do we trust the standard model? It can’t explain such a large portion of the universe.

PREGNANCY HORMONE HCG PROTECTS AGAINST BREAST CANCER EVEN IN SHORT-TERM TREATMENTS, April 20
One of the most effective ways to prevent breast cancer is through a full-term pregnancy at an early age. Studies out of Fox Chase Cancer Center have linked this protective effect to the presence of human chorionic gonadotropin (hCG), a hormone produced by the placenta to maintain the early stages of pregnancy. Their findings in an animal model of breast cancer showed that rats exposed to hCG over a 21 day period (the length of rat pregnancy), are far less likely to develop breast cancer when exposed to a known carcinogen.

SURVEY IDENTIFIES FACTORS ASSOCIATED WITH EARLY DETECTION OF MELANOMA IN OLDER MEN, April 20
Older men whose melanoma is detected by a physician are more likely to have thinner and therefore more treatable tumors at diagnosis, according to results of a survey published in the April issue of Archives of Dermatology, one of the JAMA/Archives journals. A second analysis of the same survey data finds that physician detection of thin melanoma is more common in those who are 65 or older, have cancers on their backs or who have a history of atypical moles.

OUR BRAINS MAKE THEIR OWN MARIJUANA: WE'RE ALL POT HEADS DEEP INSIDE, April 20
U.S. and Brazilian scientists have just proven that one of Bob Dylan's most famous lines—"everybody must get stoned"— is correct. That's because they've discovered that the brain manufactures proteins that act like marijuana at specific receptors in the brain itself. This discovery, published online in The FASEB Journal, may lead to new marijuana-like drugs for managing pain, stimulating appetite, and preventing marijuana abuse.

CONTROLLING OUR BRAIN'S PERCEPTION OF EMOTIONAL EVENTS, April 20
Research performed by Nicole Lauzon and Dr. Steven Laviolette of the Schulich School of Medicine & Dentistry at The University of Western Ontario has found key processes in the brain that control the emotional significance of our experiences and how we form memories of them. A lack of proper brain function in this area is what lies beneath such conditions as Schizophrenia and Post-Traumatic Stress Disorder (PTSD). In people who suffer from these conditions emotional experiences can become distorted, causing the person to 'lose touch' with reality. The findings have been published online by The Journal of Neuroscience.

UNIVERSAL COVERAGE MAY NARROW RACIAL, ETHNIC AND SOCIOECONOMIC GAPS IN HEALTH CARE, April 20
Health care disparities in the U.S. have long been noted, with particular attention paid to the gaps separating racial and economic groups. And while some research has looked at how insurance—and lack of insurance—contributes to this imbalance, few, if any, studies have quantified the impact of universal coverage on differences in health outcomes between these groups.
