Discussions Discussion Life in the Universe
giovanni vaglini, Nov. 23, 2011

I think that inquiring into the possibility of life on other planets is a good and interesting thing, and I’d like to do it. I believe that life could exist in the Universe far from the Earth, and I don’t exclude the existence of life forms similar to the humans’ one (for me, everything is possible until the Science demonstrates I’m wrong). In my opinion the discovery of life in other planets would be a magnificent achievement of the humanity,so I’d like to study about astronomy and life when I’ll be older

Some scientists say it is impossible that there is life on other planets,others say that there may be a new form of life.I think it’s possible because if there is life on Earth can there be life on other planets …

    Do you know scientists that said that life on other planets is impossible? Can you tell me how said that?

    Sorry, who said that, not how…

I think there are life forms in the universe not yet established, does not mean human people, but small beings or micro-organisms and to exclude the presence of a Martian (hoping not to be wrong)! In this regard, I would suggest you start of scientific research as soon as possible to resolve finally this doubt !!!

I think that is possible that there is life in the universe,because has discovered that there are galaxies similar to our. But i don’t believe that that there are other humans in other planets;maybe it’s possible that there is a process of evolution similar to what happened on Earth millions of years ago… So i think that this story of the aliens isn’t an invention…

    I think it is possible because some studies talk about the existence of other universes so it is possible that other lifes developped like our one.

I think there is life in the universe, in fact, the existence of galaxies and planets with characteristics similar to ours makes it likely that there are other life forms. You have a confirmation from the discovery of traces of water on Mars that suggest a possible form of life.

Discussions Discussion Life on the Reef: Amazing World of Coral Fish…
Camilla Pashar, Nov. 14, 2011

Why Are We Killing Coral Reefs? Coral reefs are likely to become the first ecosystem completely destroyed by humans, predicts Dr. Peter Sale, a leading United Nations ecologist. His new book, Our Dying Planet, explains:

http://switchboard.nrdc.org/blogs/dnewman/within_the_next_century_coral.html

“It is not pollution, or overfishing, or mass bleaching, or climate change, or any of the other factors I have mentioned that is killing our coral reefs. It is all of these factors together. Or, to put it more plainly, the cause of the destruction of coral reefs is us.”

The only possible silver lining is that we still have the power to reverse course and save at least some of these magical living communities. But, change must come quickly.

Peter Sale, discusses evidence of the wholesale destruction of coral reefs in the interview below:

It has been found that participation in regular aerobic exercise is effective at enhancing cognitive and brain health in late adulthood. This was initially thought to only occur in mice, but now we have seen this occur in humans also, Cardiorespiratory fitness and aerobic exercise augments cognition by increasing gray matter volume in prefrontal and hippocampal brain regions

Discussions Discussion Molecular and Cell Biology
Dan Thompson, Oct. 28, 2011

Biology discovery – It turns out that the python’s heart balloons in size as it digests - similar to the larger-than-normal heart of an Olympic athlete.

It’s this amazing biology,” said Leslie Leinwand, a molecular biologist at the University of Colorado Boulder. “They’re not swelling up. They’re building (heart) muscle.”

Their metabolism rises more than 40-fold, and their organs immediately start growing in size to get the digesting done. The heart alone grows a startling 40 percent or more within three days.

The implications for people?

The scientists found that a specific combination of three fatty acids in the blood helped promote the healthy heart growth of the python. Sure enough, injecting living mice made their hearts grow in an apparently healthy way as well.

If the same underlying heart signals work in animals as divergent as snakes and mice, “this may reveal a common universal mechanism that can be used for improving cardiac function in all vertebrates, including humans.

The video shows another group of scientists on the path to the same discovery a few years ago.
