The synthetic marijuana product Spice
Synthetic, or designer, drugs are chemical compounds that imitate the effects of marijuana, stimulants, and other recreational drugs. Unlike illegal substances, synthetics are easily accessible to users who want to get high without risking legal repercussions. Although the Federal Analog Act of 1986 prevents the sale of chemicals with structures that are “substantially similar” to those of illegal drugs, it only applies to drugs intended for human consumption. Manufacturers easily leap this hurdle by labeling their synthetic drugs as non-ingestible products such as incense, potpourri, or bath salts. Taking a different tack, the government recently passed the Synthetic Drug Abuse Prevention Act of 2012, which makes some of the popular designer drugs illegal. But did this really make synthetics less available?
Cardiomyocytes damaged by a heart attack
What’s the News: Scientists are devoting countless research hours to treatments based on embryonic stem cells, differentiating these blank-slate cells from embryos into brain cells, light-sensing retinal cells, blood cells, and more to replace damaged or destroyed tissues in the body. Now, a new study in mice shows such that nature has arrived at just such a solution, too: When a pregnant mouse has a heart attack, her fetus donates some of its stem cells to help rebuild the damaged heart tissue.
What’s The News: Three 16-year-old teenage boys in Texas had heart attacks shortly after smoking a product called k2, or Spice, according to a study published this month in the journal Pediatrics. The report highlights a growing public health problem: the increased availability and use of synthetic cannabinoids, which when smoked mimic the effects of marijuana but typically can’t be detected in drug tests. While the U.S. Drug Enforcement Agency secured an emergency, one-year ban of five synthetic cannabinoids in March of this year, most of the hundreds of such chemicals remain basically legal, widely available, little understood, and potentially harmful.
Dick Cheney may not have a pulse, but part of his ticker is spinning at 9,000 RPM.
The former Vice President provided an instant laugh line for comedians this week when it was revealed that during his latest heart surgery, doctors installed a new implant called left ventricular assist device, or LVAD.
The pump runs something like a drill bit, continuously rotating at 9,000 rotations per minute rather than squeezing and releasing, so Cheney now officially has no pulse, according to Dr. Stuart D. Russell, chief of heart failure and transplantation at Johns Hopkins’ Comprehensive Transplant Center [Baltimore Sun].
A device like Cheney’s is implanted in his chest, with the exception of the batteries, which the user must wear in a separate vest. (Though the Baltimore Sun reports that patients can wear the power source “holster style,” which may be more Cheney’s style.)
