Popular intoxicants: what lessons can be learned from the last 40 years of alcohol and cannabis regulation? UCSF Study Finds Pot Smoke Less Harmful Than Tobacco. CBS SF Bay (con't) Affordable Care Act Updates: CBSSanFrancisco.com/ACA Health News & Information: CBSSanFrancisco.com/Health SAN FRANCISCO (CBS/AP) – Smoking a joint once a week or a bit more apparently doesn’t harm the lungs, suggests a 20-year study that bolsters evidence that marijuana doesn’t do the kind of damage tobacco does.
The results, from one of the largest and longest studies on the health effects of marijuana, are hazier for heavy users—those who smoke two or more joints daily for several years. The data suggest that using marijuana that often might cause a decline in lung function, but there weren’t enough heavy users among the 5,000 young adults in the study to draw firm conclusions. Still, the authors recommended “caution and moderation when marijuana use is considered.” Marijuana is an illegal drug under federal law although some states, like California, allow its use for medical purposes. Study co-author Dr. Mars Rover Curiosity Update: Self Portrait & New Images Released, First Destination Announced (PHOTOS) NASA on Friday released the latest images to be sent back by the Mars Rover Curiosity, including a high-resolution self-portrait taken by the rover's Navigation camera.
According to NASA, the portrait, available below, is composed of a mosaic of 20 images taken on Aug. 8, just several days after the rover landed on Mars. Richard Muller: 'Humans Are Almost Entirely The Cause' Of Climate Change. New Particle at World's Largest Atom Smasher is Likely Higgs Boson. Physicists are more than 99 percent sure that they've found a new elementary particle that is likely the long-sought Higgs boson.
Evidence for the new particle was reported today (July 4) by scientists from the world's largest atom smasher, the Large Hadron Collider in Switzerland. Researchers reported they'd seen a particle weighing roughly 125 times the mass of the proton, with a level of certainty that all but seals the deal it's the Higgs boson. "This is indeed a new particle. We know it must be a boson and it’s the heaviest boson ever found," Joe Incandela, spokesperson for LHC's CMS experiment, said in a statement.

Black Holes May Roam Universe Freely, Without Galaxies, Study Suggests. By Ron Cowen (View original article) Even gravitational monsters can get the heave-ho.
Two mysterious bright spots in a disheveled, distant galaxy suggest that astronomers have found the best evidence yet for a supermassive black hole being shoved out of its home. Cancer News, Video and Gossip - Gawker. Skin from heart attack patients transformed into beating heart cells. Skin cells from patients with advanced heart failure were turned into beating heart cells in a dish that were young and healthy.
Video: Lior Gepstein Link to video: Beating heart muscle cells created from skin cells Scientists have turned skin tissue from heart attack patients into fresh, beating heart cells in a first step towards a new therapy for the condition. The procedure may eventually help scores of people who survive heart attacks but are severely debilitated by damage to the organ. Is Scopolamine the world's scariest drug? The drug, called scopolamine, also known as ‘The Devil’s Breath,' is derived from a particular type of tree common in Colombia called the Borrachero tree.
The word "borrachero," which roughly translates to "get-you-drunk," grows wild in Bogota,Colombia. This tree which naturally produces scopolamine is so famous in the countryside that mothers warn their children not to fall asleep below its cunningly beautiful yellow and white flowers. "We probably should put some sort of fence up," jokes biologist Gustavo Morales at Bogota's botanical gardens to Reuters, eyeing children playing with borrachero seeds everywhere. The pollen alone is said to conjure up strange dreams. Read more...

Is drinking soda really that bad for you? Sugar sweetened beverage consumption has increased significantly Men consume on average 178 calories per day from sugar sweetened beveragesSoda often displaces more healthful items in the diet Editor's note: Dr.

Photo: Rob Homer Eating too much sugar can eat away at your brain power, according to US scientists who published a study showing how a steady diet of high-fructose corn syrup sapped lab rats' memories. Researchers at the University of California Los Angeles (UCLA) fed two groups of rats a solution containing high-fructose corn syrup - a common ingredient in processed foods - as drinking water for six weeks.
One group of rats was supplemented with brain-boosting omega-3 fatty acids in the form of flaxseed oil and docosahexaenoic acid (DHA), while the other group was not. Before the sugar drinks began, the rats were enrolled in a five-day training session in a complicated maze. Huge "Structure" of Satellites Found Orbiting Milky Way. A huge "structure" of satellite galaxies and star clusters has been found wheeling around the Milky Way, according to a new study. The discovery surprised scientists, in part because the structure might spell trouble for theories of dark matter, the mysterious, invisible substance that's thought to make up about 23 percent of the mass in the universe.
The finding is only the latest to question dark matter's existence—last week, for instance, astronomers announced that they'd failed to detect dark matter in the sun's neighborhood, even though the substance should be there, according to accepted theory. In the new study, led by Marcel Pawlowski of the University of Bonn in Germany, astronomers reconstructed the locations of the Milky Way's known satellites using sources ranging from 20th-century photographic plates to recent images from the Sloan Digital Sky Survey.
