Brain Differences in College-Aged Occasional Drug Users

Researchers at the University of California, San Diego School of Medicine have discovered impaired neuronal activity in the parts of the brain associated with anticipatory functioning among occasional 18- to 24-year-old users of stimulant drugs, such as cocaine, amphetamines and prescription drugs such as Adderall.

A research team in Spain has the enviable job of testing out new electromechanical gear for potential use in future missions to the "Red Planet." They do it within their Mars environmental simulation chamber, which is specially designed to mimic conditions on the fourth planet from the sun -- right down to its infamous Martian dust.

First Stem Cell Study of Bipolar Disorder Yields Promising Results

What makes a person bipolar, prone to manic highs and deep, depressed lows? Why does bipolar disorder run so strongly in families, even though no single gene is to blame? And why is it so hard to find new treatments for a condition that affects 200 million people worldwide? New stem cell research may help scientists find answers to these questions.

Guideline: Medical Marijuana in Pill Form or Oral Spray May Ease Some MS Symptoms; Little Evidence Other Complementary or Alternative Therapies Work

A new guideline from the American Academy of Neurology suggests that there is little evidence that most complementary or alternative medicine therapies (CAM) treat the symptoms of multiple sclerosis (MS). However, the guideline states the CAM therapies oral cannabis, or medical marijuana pills, and oral medical marijuana spray may ease patients’ reported symptoms of spasticity, pain related to spasticity and frequent urination in multiple sclerosis (MS). The guideline, which is published in the March 25, 2014, print issue of Neurology®, the medical journal of the American Academy of Neurology, states that there is not enough evidence to show whether smoking marijuana is helpful in treating MS symptoms.

A new microfluidic method for evaluating drugs commonly used for preventing heart attacks has found that while aspirin can prevent dangerous blood clots in some at-risk patients, it may not be effective in all patients with narrowed arteries. The study, which involved 14 human subjects, used a device that simulated blood flowing through narrowed coronary arteries to assess effects of anti-clotting drugs.

Bariatric Surgery Decreases Risk of Uterine Cancer

Researchers at the University of California, San Diego School of Medicine and Moores Cancer Center report that bariatric surgery resulting in dramatic weight loss in formerly severely obese women reduces the risk of endometrial (uterine) cancer by 71 percent and as much as 81 percent if normal weight is maintained after surgery.
