Unhealthy diet. Remembering. Echoes from the past.
Fat cells seem to remember unhealthy diet. A study shows that these cells can be damaged in a short amount of time when they are exposed to the fatty acid palmitate or the hormone TNF-alpha through a fatty diet. Just 24 hours of exposure to those substances is all it takes for a so-called precursor…

Killing humans. By analyzing rocks. [Brake that rock!]
University of California, Berkeley neuroscientists have tracked the progress of a thought through the brain, showing clearly how the prefrontal cortex at the front of the brain coordinates activity to help us act in response to a perception. Recording the electrical activity of neurons directly from the surface of the brain, the scientists found that…

Butterflies. Before we had flowers…
Visiting a colleague in Germany in 2012, Boston College Research Professor Paul K. Strother was examining soil samples for pollen, spores, pieces of plants and insect legs - organic debris that might otherwise have been considered "pond scum" when it was trapped in sediment during cataclysmic earth events 200 million years ago. The slides of…

True frogs… Ageing… False theories...
New research shows, in contrast to expectations, 'the rapid global range expansion of true frogs was not associated with increased net-diversification.' (1) And the examples of problems in the current evolution theory (Theory of Evolution – ToE) do not end here. As Charles Darwin explained, natural selection results in the fittest individuals for a given…

The transition to life. mRNA translation. The futility of life questions.
The transition from an egg to a developing embryo is one of life's most remarkable transformations. Yet little is known about it. Now Whitehead Institute researchers have deciphered how one aspect - control of the all-important translation of messenger RNAs (mRNAs) into proteins - switches as the egg becomes an embryo. That shift is controlled…
