It sounds like science fiction, but it seems that bacteria within us—which outnumber our own cells about 100-fold—may very well be affecting both our cravings and moods to get us to eat what they want, and often are driving us toward obesity. In an article published this week in the journal BioEssays, researchers from UC San Francisco, Arizona State University and University of New Mexico concluded from a review of the recent scientific literature that microbes influence human eating behavior and dietary choices to favor consumption of the particular nutrients they grow best on, rather than simply passively living off whatever nutrients we choose to send their way....…

One of the mysteries of the deepest branch of life may be solved. Why Archaea and bacteria are different and how they got that way is being studied by University College London - UCL. http://www.sciencedaily.com/releases/2014/08/140812121731.htm?

Tests that have been repeated by NASA shows that an engine that produces thrust with no propellant. How it works is not yet known but it has been demonstrated to work. http://sploid.gizmodo.com/nasa-reveals-new-impossible-engine-can-change-space-t-1614549987/ Has anyone else read of this? I have no idea how this could work, it seems too good to be true but it has been repeatedly tested...

No one knows what caused these craters, but Russian scientists are studying them. If they are caused by the release of underground methane hydrate and the amount yet frozen is large, we could see worldwide temperatures rise very quickly.

http://www.sciencedaily.com/releases/2014/01/140116085105.htm I think this is quite fascinating and could benefit future discoveries about the human brain. What does everyone think?

Could some of it be photons spontaneously created by dark energy?

IMO this is no surprise, and the mental damage seems irreversible.

http://newsoffice.mit.edu/2014/new-spongelike-structure-converts-solar-energy-into-steam-0721 MIT announced today that with only 10X the solar intensity of a sunny day they can convert 85% of the solar energy into steam. This could be used for desalination as an example

In the nick of time, or too late?

Scientists create black material the absorbs all but 0.035% of light, http://www.extremetech.com/extreme/186229-its-like-staring-into-a-black-hole-worlds-darkest-material-will-be-used-to-make-very-stealthy-aircraft-better-telescopes Now that's "Dark matter".

These are a partial case for being vegan.

Non-Newtonian or shear thickening fluids can turn solid when pressure is applied hard enough and quick enough. Oobleck is a mix of cornflour and water in just the right proportions, forming such a liquid. You can run across a pool of Oobleck, apparently, because your feet it hard enough and fast enough to form a solid layer, but walk and you are sunk. These materials have been explored for use in body armour, but while they may stop bullets, the weakeness is the slow knife still penetrates, as they remain liquid. We have long since been wondering if we can exploit these peculiar properties of Oobleck for rock breaking in controlled ways. We performed a series of tests…

Thank you.

Can this product rival 3D printing of buildings?

The efficiency of this engine is high, which is great, and it appears to be lighter weight than a rotating alternator-engine combination, which would be another advantage.

It is good that solar and wind power are being installed at record rates, to help offset this loss of power.

If I am not mistaken, there was a new hypothesis made by a university in the USA regarding the new calculation about the speed of light. This hypothesis explains why the light from SN 1987 A delays for 4.7 hours upon arriving on Earth. The neutrino should come first in 3 hours time then followed by light beam. But the light beam took 7.7 hours upon reaching Earth. So, maybe Einstein was wrong.

First I've heard of this idea for dark matter and energy. It sounds promising.

England's hypothesis now needs to be tested. If it is valid, then life should be common in the Universe. However, IMO it says very little about the probability of technological cultures occurring.

For the first time I knew that quantum mechanics can have application on birds. http://guardianlv.com/2014/06/birds-that-use-quantum-mechanics-to-migrate/

Perhaps technology development by intelligent life is an exceptionally rare event.
