Award-winning HBO series “From the Earth to the Moon”

Even though we’ve been able to study the moon more than any other celestial object, astronomers still aren’t sure how it was created. They do have many ideas though. The “Fission Theory” contends that the moon split off from the Earth as our planet was forming. A bulge developed, separated, and split in two, thus forming both the moon and Mars. Another idea purports that the Earth and moon were formed at the same time out of whirling swarms of cosmic dust and gas collected by gravity. The two objects were close enough together to stay permanently paired by the gravitational pull. Many scientists don’t like this idea because they claim that the Earth and moon are composed of different elements. They think the moon formed somewhere else in the solar system and was later captured by Earth’s gravitational pull. Yet another idea, and currently the most popular moon formation theory, goes like this: a celestial body crashed into the Earth and sprayed enormous amounts of debris back into space. The debris then came together to form the moon.

When is My Child Ready to Get Dressed on Her Own?

Children love to pick out their own clothing and get dressed by themselves. But a child has to develop a certain amount of motor coordination in order to perform this task. Here are some guidelines for deciding that your child is ready:

Age range: 4 to 5 years

Signs of readiness: By age two, your child may want to control the dressing routine, demanding to put on his own socks, shirt, pants, and shoes. It’s a great time to encourage him, but he will probably still need help finishing the job. Children generally have little trouble pulling on T-shirts and shorts by age three, but zippers, buttons, and tucked-in shirts pose more of a challenge. By age four or five, though, they should have the entire system down.

There are many groups of unsung heroes in medical centers who go about their work and rarely toot their collective professional horns. However, sometimes it becomes necessary to speak out and take charge when the profession itself is in danger of experiencing a shortage of qualified staff. Such is the case with clinical lab scientists (CLS) in California, who have joined forces to create awareness regarding the importance of their work and the need for a generation of new CLS professionals to join the workforce.
