New Evidence For The Moon Impact Theory – The Daily Orbit
How was our moon actually formed?
Stem cell research goes 6 feet deep
And better barley for a better beer? I bet that got your attention!
All that and more coming up on the Daily Orbit!
Hello and welcome to the Daily Orbit. I’m Emerald Robinson. The giant moon mother Theia comes straight at Earth, colliding in a blaze of glory–and our moon is born! No, it’s not a mythologically-inspired film starring Brad Pitt, but the theory of the formation of the moon. Although the theory that a giant impact formed the Earth-Moon system has been long accepted, new evidence says that it might not have happened as we previously thought. The former theory suggests that a proto-planet much smaller than earth collided with our planet and that the moon was mainly composed of material from this impacting body. However, the new model suggests that the colliding body was larger, about 4 to 5 times the mass of Mars, giving the moon a composition much more similar to the Earth’s mantle. And hence the moon is born to shine light upon us mere mortals.
Think visiting the doc will keep the old ticker going? Maybe not! A new study from England says that regular check-ups at the doctor don’t decrease instances of patients dying of cardiovascular disease and cancer. The study was conducted to examine the benefit of England’s policy of offering free yearly healthcare checkups for its citizens between the ages of 40 and 74. They found that there was virtually no difference in fatalities between those who got regular check-ups and those who did not. So I guess a regular check-up we could say won’t keep the doctor away. So just stick to eating apples.
“I see dead people…” in stem cell research. Yep, the ever controversial field of stem cell research has moved to new depth…well six feet under to be exact. New research has discovered a method of harvesting stem cells from the scalp and brains of recently deceased cadavers. They found that stem cells taken from the brain were 16 times more likely to grow into more mature stem cells than those taken from the scalp. Scientists say that using stem cells from cadavers will help propel the research without getting into the messy issue about embryonic stem cells. I think harvesting stem cells from dead people sounds pretty messy myself.
Anywhooo…Okay all you little science boys out there…I am going to act like your Mommy for a minute and tell you to take your vitamins! New research says that men who take a daily multivitamin can reduce their risk of cancer by 8%. The researchers said that although multi-vitamins are primarily taken to prevent nutritional deficiencies, their findings suggest that the supplements can be used in the prevention of cancer in middle-age and older men. They do not know specifically which vitamins contribute to this result or if the same is true for women or men younger than 50. So take your vitamins little boys…they come in chewables too. Yum…fruity.
Now here is science that can really be of benefit for the common good of the population…mapping the genome of barley for better beer. Scientists say that by doing this they can produce barley that can better withstand climate change and is disease resistant resulting in larger yields and a higher nutritional value and, they added, produces better beer and whiskey. An interesting fact about the barley genome—its twice the size of the human genome making it a bit of a challenge to map. But it’s not all about the beer, scientists says that mapping out the barley genome along with wheat and rye may help address the challenges of feeding the world’s growing population. So if, as they say, the nutritional content of barley will be higher, does that mean beer will be more nutritional? Hmmm… 😉
That does it for today’s Daily Orbit. Hmm…Yep, that’s what I’m talking about!
