Science is knowledge that refutes myth, superstition, and conjecture…
It has the power to dissolve ignorance, cure illness, and is the main process by which necessity births invention…
To describe nature, the world and the cosmos without referencing mythology is the key to the scientific method.
Without this freedom, we would not be where we are today, and if we should ever lose this freedom, we will go no further in our scientific pursuit…
But for today, we still have this freedom and there for we still have
This week in science… coming up next

What Did Philae Do?
The little ESA lander on comet 67P, skipped to a stop in the lee of some kind of ridge last Wednesday morning. It’s location made energizing the craft with solar energy impossible, so scientists enacted a plan to use the craft’s batteries to do as much science as possible before they failed. The first result has come back from a German instrment, indicating that there are organic molecules on the comet.

Triclosan Does What?
A new study finds that long-term exposure to triclosan in mice leads to liver fibrosis and cancer.

Black Holes Spooky Quasars
Scientists working with data from the VLT found that quasars line up with the filaments of the universe.

The latest of the Pigeon Hypotheses
The newest research data suggests pigeons have a gyroscope in their brain, so it is gravity, and not magnetism, nor mental maps, that guide them home.

Bear hunting kills a lot more bears than just that prize specimen
Infanticide increased and Fecundity (reproductive success) decreased in times of high hunting pressure. This is a triple-whammy on these very important top predators.

Of Mice And Men
According to the mouse ENCODE Consortium, mice and humans share many genetic elements and pathways, but there are differences that should be used to inform future research.

Sea Stars A’wastin
Researchers from Cornell University led a team of scientists in search of the cause of a sudden and devastating wasting disease in Pacific Ocean sea stars. The effort has identified a viral vector called a densovirus as the possible cause, leading scientists to home in on what is being described as Sea Star associated Densovirus.

Not a surprise…
Banking ethics are not found in bankers.

Fruit flies succumb to peer pressure
Fruit flies will often conform to societal norms, unless previously trained for other behavior. So, flies are not complete sheep, but there are definitely sheepish undertones…

Old brains just as moldable
Researchers found changes reflecting plasticity in the brains of older people, but not in the same places as in younger brains.

Trans Fats Bad For MemoryTumeric Time!SCN And MemoryShift Work And MemoryNo Nighttime Iron?
A number of studies this week point to ways that our diet and lifestyle influence our brain and body. Some foods contain components like trans-fat, which are bad for memory, while others contains like tumeric seems to boost memory. Additionally, when we sleep can affect the functioning of our SCN, and lead to declines in memory ability over time. It is also possible that lack of synchrony between the brain and organs like the liver can influence metabolic problems.

Calorie Restrict Your Brain
The gene profiles of female mice fed 30% fewer calories than controls were less likely to mirror the changes that occur with aging.

Kiss Of Bacteria
Kissing for 10 seconds allows the transfer of up to 80 million bacteria between partners.
