Ben-Gurion U. researchers reveal connection between cancer and human evolution

BEER-SHEVA, ISRAEL, July 2, 2009 Researchers at Ben-Gurion University of the Negev (BGU) have discovered that gene mutations that once helped humans survive may increase the possibility for diseases, including cancer. The findings were recently the cover story in the journal Genome Research . ...

MU study finds connection between evolution, classroom learning

COLUMBIA, Mo. Over thousands of years, humans have evolved to naturally understand things like facial expressions and social interactions. But a University of Missouri researcher has found there is an ever-widening gap between what humans can naturally learn and what they need to learn to be succ...

Ten genes identified in connection with sudden cardiac death

Study helps explain connection between sleep apnea, stroke and death

BETHESDA, Md. (Jan. 6, 2009) − Obstructive sleep apnea decreases blood flow to the brain, elevates blood pressure within the brain and eventually harms the brain's ability to modulate these changes and prevent damage to itself, according to a new study published by The American Physiological...

Study finds possible connection between marijuana abuse and stroke or heart attacks

Long-term harmful effects of marijuana (MJ) include risk for heart attacks and strokes in addition to impaired learning and memory.

UCLA study identifies mechanism behind mind-body connection

BACKGROUND: Every cell contains a tiny clock called a telomere, which shortens each time the cell divides. Short telomeres are linked to a range of human diseases, including HIV, osteoporosis, heart disease and aging. Previous studies show that an enzyme within the cell, called telomerase, keeps ...

The kapok connection -- Study explains rainforest similarities

Celebrated in Buddhist temples and cultivated for its wood and cottony fibers, the kapok tree now is upsetting an idea that biologists have clung to for decades: the notion that African and South American rainforests are similar because the continents were connected 96 million years ago. Researc...

Age-related changes in DNA repair illuminate the connection between age and genetic damage

Researchers have uncovered a new way in which the aging process is linked to DNA damage--which occurs normally as a result of cell metabolism and environmental influences--and the various ways in which cells repair that damage. In the new work, researchers found that cells in young fruit flies make...

Novel connection found between biological clock and cancer
