Smoking, steroids, illegal drugs, and 3rd grade retention?

Smoking, steroids, illegal drugs, and 3rd grade retention?

Imagine that someone offered you something and said, "This might give you a short-term performance boost. If it does, we're not sure how long the effect will last but we know it will diminish over time. The boost might be just a year or two and it's all but certain that it won't last more than three or four years. Moreover, it's extremely probable that after that you will suffer significant negative consequences FOR THE REST OF YOUR LIFE. Do you want it?"

You might take that gamble if you were a professional athlete (see, e.g., steroids), but most of us would not. In the case of smoking, illegal drugs, alcohol, and (sometimes) fatty foods, the government actively discourages us from making that choice. But when it comes to 3rd grade retention, some state governments not only are allowing the choice but requiring it.

I know you're 8. Take a puff!

U.S. Navy controls inventions that claim to change "fabric of reality"

Inventions with revolutionary potential made by a mysterious aerospace engineer for the U.S. Navy come to light.

Surprising Science
  • U.S. Navy holds patents for enigmatic inventions by aerospace engineer Dr. Salvatore Pais.
  • Pais came up with technology that can "engineer" reality, devising an ultrafast craft, a fusion reactor, and more.
  • While mostly theoretical at this point, the inventions could transform energy, space, and military sectors.

  • As the material that makes all living things what/who we are, DNA is the key to understanding and changing the world. British geneticist Bryan Sykes and Francis Collins (director of the Human Genome Project) explain how, through gene editing, scientists can better treat illnesses, eradicate diseases, and revolutionize personalized medicine.
  • But existing and developing gene editing technologies are not without controversies. A major point of debate deals with the idea that gene editing is overstepping natural and ethical boundaries. Just because they can, does that mean that scientists should be edit DNA?
  • Harvard professor Glenn Cohen introduces another subcategory of gene experiments: mixing human and animal DNA. "The question is which are okay, which are not okay, why can we generate some principles," Cohen says of human-animal chimeras and arguments concerning improving human life versus morality.

Physicists push limits of Heisenberg Uncertainty Principle

Surprising Science
  • New experiments with vibrating drums push the boundaries of quantum mechanics.
  • Two teams of physicists create quantum entanglement in larger systems.
  • Critics question whether the study gets around the famous Heisenberg uncertainty principle.
