The idea is to use the power of bacteria to turn toxic waste gases into valuable compounds such as acetate or ethanol. These can be used afterwards as biofuels or basic compounds for synthetic materials. The first real-siz

However, some problems in physics are unknown or cannot be represented in detail mathematically on a computer. Researchers developed a new method that brings physics into the machine learning process to make better predictions. The researchers used turbulence to test their method.

Side effects often attributed to statins were the same for those taking a placebo
Study participants who reported side effects from cholesterol-lowering medications known as statins also reported the same side effects when they unknowingly took placebo pills.These side effects are real, and it appears may be mostly due to the psychological rather than the pharmacological effects of statins since symptoms were consistent when taking the placebo.

Sweating is a natural function of the human body, allowing a body to cool itself as sweat emerges from glands and evaporates.

A deodorant kills the bacteria that produce the odor, while an antiperspirant clogs sweat ducts to prevent sweat from emerging in the first place.
