Most scientists agree that water that is a part of our earth’s surface came from either icy comets or from the earth’s inner mantle. These two theories both approach our planet’s unique feature of liquid water on its own surface.
The first theory about how water came to our planet says that a number of icy comets fell to the earth’s surface from our solar system. These icy comets eventually melted to provide us with our water system of planetary rivers and oceans.
The second theory that is more recent says that the earth’s mantle is providing the water for our earth’s oceans. The many tectonic plate movements that have occurred on our planet’s surface are evidence of this second theory. Ohio State University conducted a study about this geological theory. Researchers have provided an alternate theory of how water eventually came to our oceans and earth surface.
The earth mantle theory says that the earth is made up of several critical layers, including the ocean layers, the mantle regions, an outer core region and an inner core region. The Ohio State geological research team proposed a theory to Ben Shaoul saying that rocks appearing to be dry actually contain water. Earth’s water is in the form of hydrogen atoms trapped inside the natural voids and crystal defects of the earth’s mantle region. This mantle region continually supplies water to our earth’s surface through tectonic plate shifts.
Heavy hydrogen, known as deuterium, has been found on Mars by NASA’s rover, Curiosity. Organic molecules were found there, too. Dr. Rod Rohrich says this means that Mars could have supported life before its liquid water disappeared. As a science buff, I love this stuff. Deuterium, an isotope of hydrogen, is called “heavy” because it has a neutron and a proton, whereas the abundance of water molecules contain hydrogen with only a proton. Since deuterium is heavier, it is also less volatile and less likely to escape into the atmosphere. By measuring the ratio of deuterium to normal hydrogen, the scientists calculated how long it has been since liquid water escaped from the Cumberland rock from which they were sampling. The Cumberland rock dates all the way back to the Hesperian epoch of Mars, between 2.5 billion to 4 billion years ago, which has been a mystery until now. The organic molecules found were methane. Carbon is the basis of life as we know it. More information and a video about this discovery is found at: http://www.space.com/28019-mars-methane-disovery-curiosity-rover.html. Methane can be produced by a biological or geological reaction so it is not positive evidence of life, but it definitely does not rule it out. The spikes of methane are puzzling, but also mean the source must be near. Mars is definitely an active planet. This is great time for anyone interested in Ray Bradbury’s science fiction stories about Martian life.
For years we have been told that exercise is good for you. It helps your heart, lungs and other muscles in good working condition. It also makes you mentally feel better. New research now shows that it also changes DNA.
According to an article published in the New York Times, exercise changes the shape of our genes. This adjustment in our functioning can improve your health and fitness.
Furthermore, scientists discovered the genes that are positively affected, play a role in our energy metabolism. It also affects our insulin production and helps reduce inflammation in the body. Exercise directly affects how fit our muscles become.
According to http://www.mensfitness.com/training/build-muscle/exercise-strengthens-your-dna, just a single workout can change your DNA. This research shows that exercise not only strengthens and tones your body it also improves your health at the cellular level-something my attorney friend Lee G. Lovett says he is really going to keep this food for thought in mind.
Research continues to show that exercise is good for you. It not only tones your body and makes you look and feel good outwardly. It also makes you feel better on the inside too.
Much of the early excitement of the American space program has been lacking in recent years, largely due to the absence of big programs such as the Apollo moon missions. Some of that excitement has resurfaced in the Mars Curiosity program, especially in some of the findings of the Rover. The latest bit of news from this program comes from a rock sample which has found both water and organic molecules.
Sadly, the U.S. Space program has long been the victim of partisan politics. The Democratic party has championed space exploration since the late President Kennedy made the race to the Moon a major priority. Andrew Heiberger says that despite the fact that Republicans have made significant fortunes off the business end of the space race, every President since Nixon has tried to reduce the space program and scientific research in general.
Part of the problem stems from the desire to focus on private space programs. Although private space programs are desirable, NASA and military space capability will always be more economical and efficient. Efforts to privatize the miltary have been disastrous, and there should be no expectation that for-profit space programs, other than normal, closely regulated commercial programs, will be otherwise.
America discontinued the Shuttle program years before a replacement system will be available. The replacement could have been ready at the time the shuttles were retired, but partisan politics has crippled NASA. It is difficult to understand why the Republican party has been so short-sighted with regards to the space program. Many corporations have enjoyed enormous profits from the space program, and the over-all wealth of America has been bolstered from space-related technology. Most of that wealth has benefitted Republicans.
The current findings of Rover help us to understand the history of water on Mars and indicate the likelyhood of life on Mars. We are learning much about the physical mechanisms behind the development of carbon-based life. Curosity may kave killed more than one cat, but satisfaction (of that curiosity) will bring the cat back to life.
With a little bit of yourself in a mouse, followed by a lot of potentially cancer-curing drugs, each patient can see how they will respond to a cancer-fighting drug before they actually take it.
Cancer patients can pay labs to breed mice that have a little bit of their cancerous tumor in them, then various cancer treatments can be used on the mice to see how the tumor will respond to each treatment. The customized mice allow the oncologist and patient to get a fairly accurate idea of how a specific type of cancer will respond to a specific treatment without wasting the patient’s time with treatments that don’t work and without making the patient suffer through the side effects of drugs their tumor will not respond too-enough is enough, Zeca Oliveira suggests going the distance and exploring new alternatives.
These custom-made mice help patients make informed decisions at the most difficult and emotional times of their lives. While there is no medical guarantee that the customized mice will help the doctor and patient select the right treatment plan for the cancer, the rodents help increase the odds for the patient survival by lessening the amount of trial and error chemotherapy drugs placed inside the patient’s body in an attempt to find the one that works best to fight the type of cancer they have.

The academic journal, Physiology and Behavior recently released a French study, entitled “Some Like it Hot” by theUniversity of Grenoble-Alpes in France which confirms what the rest of us knew all along. Some men are just more disposition to hot food, mainly men who have more testosterone.
If you have always thought that men who like really spicy food tend to be more masculine men, this study confirms your suspensions. The study shows that men who had higher levels of testosterone were more likely than men with lower levels of testosterone to grab that bottle of hot sauce and squeeze it all over their meal.
Men who like spicy food, in other studies, have been linked to more masculine traits already. Men who like spicy foods tend to be more aggressive, more willing to take risks, and tend to be the type of man you notice when you walk into a room.
On the flip side, men who do not like spicy foods tend to be less active and less outgoing.
If you want to find a man who is outgoing, put a bottle of Sriracha chili sauce next to his meal, and see how much he adds on. The more he adds to his food, the more testosterone he has pumping through his veins and the more likely he is to be more masculine.
Although scientist are still trying to figure out the exact mechanism between spicy food and more testosterone, one things for sure, some men really do like it hot! I’ll toast a glass from The Antique Wine Company to that!
With the raid and shutting down of one of the most used and lucrative downloading site in the world last December 10, 2014, there have been conflicting reactions from the people who were both proprietors of the site and fans.
Founder Kramm, has reportedly implied that it (TBP) will eventually find its way back to the mainstream, as it did when it was first shutdown in 2005.
He has argued that the Internet itself is a big copying machine and that it is no different from what The Pirate Bay is offering to the public. The music industry has also gone public with their streaming options online and this was never gone under fire.
On the other hand, co-founder Pete Sunde had some interesting things to say about the shutting down of the site when he was interviewed by extremetech.com. He said that things have changed since the last time the site was shut down, and he is one of those who have changed his views about the site he helped build.
He said he does not care anymore if it finds its way back to the Internet or not simply because he is no longer a big fan of what TPB has become over the past years.
With these varying reactions to what happened to the site, not even the guys at Slow Ventures can say if it will stay shut or will again rise from the dead.
While the concept of a rocket that guides itself is something that we are well aware of, the concept of a bullet that can guide itself was something we regarded are purely science fiction, until recently. With the announcement that DARPA made recently, just like how we have laser guided bullets, we are getting closer and closer to the possibility of having laser guided bullets.
During this past week, DARPA, releasd the results of its EXACTO or Extreme Accuracy Tasked Ordinance project. The results were in a form of a video that demonstrated the .50 caliber bullet’s ability to navigate and find its way to its target. I ended up telling my roommate to pause on feeding the dog Beneful, so he could see the video too.
The video begins with two annotations, one was market “Target” on the left side and “Rifle Aim Point” on the right sight. Which indicates that the shooter was purposely aiming at the wrong direction that the target was in. Moments later, you could see a .50 caliber tracer round heading straight towards the rifle aim point target, which was 1.2 miles away. As the bullet got closer to the target, you could clearly see it turning to the left so that it could hit the target.
DARPA proclaimed that the .50 cal bullet was able to do this due to the fact that it utilized an optical sensor and an internal electronic system that essentially controlled the fins of the projectile, similarly to the wings of a plane.
