Microscopic Pollution May Trigger Heart Attacks And Strokes By Spurrin
Thousands of people die from strokes and heart attacks within 24 hours of a spike in microscopic pollution. Scientists couldn't figure out why. New research has found that these tiny pieces of soot spur hyperclotting of the blood, resulting in heart attacks and strokes for people at risk. Previous epidemiological research has linked the pollution to cardiovascular death and disease, but this is the first study to show how it actually happens in an animal model. Discovery About Obesity Drug Helping Scientists Develop New Cancer Tre
Based on their surprising discovery that an obesity drug can kill cancer cells, scientists have made a new finding about the drug's effects and are working to design more potent cancer treatments. What's Inside A Comet? Brown Geologist Helps NASA Find Out
On July 4, scientists at NASA's Jet Propulsion Laboratory will witness fantastic fireworks when comet Tempel 1 slams into a space probe at 23,000 miles per hour. Brown University professor and NASA mission member Peter Schultz will help analyze collision data to determine what's inside this primordial ball of ice. 'Promiscuous' Area Of Brain Could Explain Role Of Antidepressants
A study at Baylor College of Medicine in Houston may lead to a better understanding of how antidepressants like Prozac work -- and how to make them more effective.According to results published in today's issue of the journal Neuron, a study in mice proposes that dopamine and serotonin neurotransmitter systems in the brain occasionally get their signals crossed, causing delays in stabilizing mood. Teen Drivers Back to School
One in eight teen drivers will have an auto accident during the year, so now is a good time to go to an accident avoidance class.. In Autopia. Neuroscientists Propose New Theory Of Brain Flexibility
Neuroscientists have put forward a new computational theory of brain function that provides answers to one of the central questions of modern science: How does the human brain organize itself to give rise to complex cognitive tasks such as reading, problem solving and spatial reasoning? Geologists Make Better Estimates Of Rock Ages, Study Global Climate Ch
Ohio State University geologists have found that important rocks from Niagara Gorge -- rock formations that are used to judge the ages of rocks and fossils around North America -- formed five times faster than previously thought. The finding means that scientists will have to re-examine studies of sedimentary rock deposited across North America during the Silurian period, from 416 to 443 million years ago.
