Re: How should sex education be taught?
I would argue that schools are responsible for teaching sex education. In an ideal situation, this education would take part in addition to the efforts of the parents in informing their children about sex. However, many parents may not feel comfortable in doing so or may not have the extensive knowledge necessary in detailing the causes and effects of specific STDs, HIV, how to use contraceptives, etc.
Sex education should be an ongoing process but should begin no late than fifth grade (age 10). The taboo on sex in North America is absurd. Humans should be educated not only about the physical act of sex but also gender and sexual identities. By this I am referring to the necessity to remove taboos on sex by informing children about masturbation, heterosexual couples, same sex couples, and people who are transgendered of transsexual.
I wholeheartedly believe that much of the hate, anger, frustration, and sexual repression existing within North America could be improved through educating children about sex and sexual identities in a complex and inclusive manner.
The one aspect of sex education I would exclude, however, is abstinence-only education because this is misinformation and tells human beings to repress and deny their natural sexual desires.
Here's the science of black holes, from supermassive monsters to ones the size of ping-pong balls.
- There's more than one way to make a black hole, says NASA's Michelle Thaller. They're not always formed from dead stars. For example, there are teeny tiny black holes all around us, the result of high-energy cosmic rays slamming into our atmosphere with enough force to cram matter together so densely that no light can escape.
- CERN is trying to create artificial black holes right now, but don't worry, it's not dangerous. Scientists there are attempting to smash two particles together with such intensity that it creates a black hole that would live for just a millionth of a second.
- Thaller uses a brilliant analogy involving a rubber sheet, a marble, and an elephant to explain why different black holes have varying densities. Watch and learn!
- Bonus fact: If the Earth became a black hole, it would be crushed to the size of a ping-pong ball.
Protected animals are feared to be headed for the black market.
In a breakthrough for nuclear fusion research, scientists at China's Experimental Advanced Superconducting Tokamak (EAST) reactor have produced temperatures necessary for nuclear fusion on Earth.
- The EAST reactor was able to heat hydrogen to temperatures exceeding 100 million degrees Celsius.
- Nuclear fusion could someday provide the planet with a virtually limitless supply of clean energy.
- Still, scientists have many other obstacles to pass before fusion technology becomes a viable energy source.
