Thus, billions of organisms die early so that a few better-adapted individuals can grow." What is even more striking, he said, is th...

Marijuana use could cause tubal pregnancies

...cal Center reported this week. The researchers studied CB1, a "cannabinoid" receptor that binds the main active chemical for marijuana, delta-9-tetrahydrocannabinol (THC). In pregnant mice that lacked the gene for the receptor, or in which the receptor was blocked, the embryo failed to go through th...
