The Science of the Lightsaber 197

Posted by samzenpus from the the-force dept.
Smartcowboy writes "Chances are that you have seen a lightsaber at one time or another, whether on the evening news or down at the local cantina. Therefore you know that a lightsaber is an amazing and versatile device that is able to cut through nearly anything in a matter of milliseconds. Have you ever wondered how these remarkable weapons work? Where does the energy come from, and how are they able to contain that energy in a rod-like column of glowing power? In this article, you will have a chance to look inside a lightsaber and discover the source of its incredible characteristics." I was sure the blade was made from the focused hate and disappointment of the last three movies.

Submission + - Marijuana raises psychosis risk? (time.com)

Submitted by Pockets
Pockets writes: (LONDON) — Using marijuana seems to increase the chance of becoming psychotic, researchers report in an analysis of past research that reignites the issue of whether pot is dangerous. The new review suggests that even infrequent use could raise the small but real risk of this serious mental illness by 40 percent.

Doctors have long suspected a connection and say the latest findings underline the need to highlight marijuana's long-term risks. The research, paid for by the British Health Department, is being published Friday in medical journal The Lancet.

"The available evidence now suggests that cannabis is not as harmless as many people think," said Dr. Stanley Zammit, one of the study's authors and a lecturer in the department of psychological medicine at Cardiff University.

The researchers said they couldn't prove that marijuana use itself increases the risk of psychosis, a category of several disorders with schizophrenia being the most commonly known.

There could be something else about marijuana users, "like their tendency to use other drugs or certain personality traits, that could be causing the psychoses," Zammit said.

Marijuana is the most frequently used illegal substance in many countries, including the United Kingdom and the United States. About 20 percent of young adults report using it at least once a week, according to government statistics.

Zammit and colleagues from the University of Bristol, Imperial College and Cambridge University examined 35 studies that tracked tens of thousands of people for periods ranging from one year to 27 years to examine the effect of marijuana on mental health.

They looked for psychotic illnesses as well as cognitive disorders including delusions and hallucinations, bipolar disorder, depression, anxiety, neuroses and suicidal tendencies.

They found that people who used marijuana had roughly a 40 percent higher chance of developing a psychotic disorder later in life. The overall risk remains very low.

For example, Zammit said the risk of developing schizophrenia for most people is less than 1 percent. The prevalence of schizophrenia is believed to be about five in 1,000 people. But because of the drug's wide popularity, the researchers estimate that about 800 new cases of psychosis could be prevented by reducing marijuana use.

The scientists found a more disturbing outlook for "heavy users" of pot, those who used it daily or weekly: Their risk for psychosis jumped to a range of 50 percent to 200 percent.

One doctor noted that people with a history of mental illness in their families could be at higher risk. For them, marijuana use "could unmask the underlying schizophrenia," said Dr. Deepak Cyril D'Souza, an associate professor of psychiatry at Yale University, who was not involved in the study.

Dr. Wilson Compton, a senior scientist at the National Institute on Drug Abuse in Washington, called the study persuasive.

"The strongest case is that there are consistencies across all of the studies," and that the link was seen only with psychoses — not anxiety, depression or other mental health problems, he said.

Scientists cannot rule out that pre-existing conditions could have led to both marijuana use and later psychoses, he added.

Scientists think it is biologically possible that marijuana could cause psychoses because it interrupts important neurotransmitters such as dopamine. That can interfere with the brain's communication systems.

In the U.K., the government will soon reconsider how marijuana should be classified in its hierarchy of drugs. In 2004, it was downgraded and penalties for possession were reduced. Many expect marijuana will be bumped up to a class "B" category, with offenses likely to lead to arrests or longer jail sentences.

Submission + - Planet could harbor Life

For the first time, astronomers have discovered a planet far, far away that might be similar to Earth. This distant world, which pirouettes around a dim bulb of a star with the unglamorous name Gliese 581, may possibly sport a landscape that would be vaguely familiar to us — a panorama of liquid oceans and drifting continents. If so, there's the chance that it's a home to life — perhaps even advanced life.
