NYT : NASA Spacecraft Appears to Have Landed on Mars

I was delighted to learn that the NASA spacecraft may have landed on Mars safely. We will find out later to see if the probe is in good shape and it may take some time to unfold things before the robotic arm starts to drill in the ice surface and collect some data.

It could help to shed some light about life and the red planet itself. I look forward to receiving some news on some analysis.

NYT : Older Brain Really May Be a Wiser Brain

Even though older adults could no longer remember names and telephone numbers, it doesn't necessarily mean that their brainpower is declining. According to findings, the brain takes time to store the data and search for the information. As matter of fact, the aging brain is more wiser. Sure, young people can readily access the information from brain relatively quickly but they are still in the learning process.

You can read an interesting article. Just click on the link below.

NYT : Supernova Remnant Is Young and Quick



The explosion of star occurred about 26,000 years ago and the light traveled to here about 150 years ago. The star resides about 26,000 light-year away from here in our own Milky Way galaxy. The supernova is so young and crispy as it's continuing the formation. The 3-D image above is spectacular!

NYT : Polar Bear Is Made a Protected Species

I'm pleased to learn that the polar bear will be placed under the protection of the Endangered Species Act. The blame goes to global warming and heavy hunting.

I wonder why it took them a long time to put the polar bear in this category? It's important for the world try to preserve endangered species and increase the regulation on hunting.

Even though this is a small step, the world need to act more to slow down the rise of global warming.

Yahoo : Earth Extinctions Blamed on Cosmic Speed Bump

Have you ever figured out what has caused the mass extinction that wiped out species like dinosaurs? A research suggested that cosmic impacts may be one of handful reasons.

As our galaxy passed through the galactic zone every 35 million to 40 million yeras, increasing the chances of comets showering at planets.

It's an interesting hypothesis. There is a reason for me to be skeptical. There has been no mass extinction for 65 million years and I want to see some more findings. I like some other theories.

Nikola Tesla

A couple days, I finished reading a fascinating biography of Nikola Tesla by Margaret Cheney. The title is Tesla: Man Out of Time. Prior to reading this book, I had no idea that I would be reading a biography of someone who was a real genius. I was astonished to learn more about Tesla's most important inventions such as radio, X-ray, fluorescent light, etc. Actually, he was a pioneer of fluorescent light and it didn't become standard until a few decades later. Other inventors have claimed that they, not Tesla, invented radio and X-ray. A couple years after Tesla's death, the Supreme Court ruled that radio was invented by Tesla. Too bad, Tesla was so indifferent on patenting some of his inventions. I believe that some of Edison's patented inventions don't belong to him.

I would highly recommend you to read this book if you are interested in learning about Tesla, his inventions, and his life. The book may be a little technical but it's very enjoyable.

NYT: H.P. Reports Big Advance in Memory Chip Design

Hewlett-Packard scientists have successfully created a simple circuit element that can build tiny powerful computers to do performs taks such as biological functions. Today, they could create the circuit based on memristors are that small as as 15 nanometers. The smallest compound in today's semiconductors are 45 nanometers.

Very impressive! For further reading, click on the link below.
