Scientists Have Unlocked the Code That Turns Genes On and Off

Knowing how or why genes are turned on and off during development, as well as understanding how they respond to environmental changes, will prove to be useful in our quest to find ways to prevent diseases. In addition, while the human initiator is responsible for regulating more than half of human genes, there are other sequences that control gene activity. This achievement could lead scientists to discover other sequence signals.

“The solution of the human Initiator code will enable us to explore new frontiers in gene regulation. In the future, it will be possible to use the code to identify other regulatory signals and, in this way, gain a more complete understanding of how human genes are turned on and off,” Kadonaga says.

The problem of quickest descent

Brachistochrone is a Greek word which translates to the shortest time, and it refers to one of the questions posed by one of the Bernoulli’s brothers; Johann Bernoulli. If you want to move from point A to B in the quickest time possible what is the shortest time you can take. Most people will assume that the straight line will be the shortest and will take the least time which isn’t true.

Yes, the Eerie Carl Sagan Prediction That’s Going Viral Is Real

Did Carl Sagan really warn about a time in the future when manufacturing jobs would slip away, when the average person would have virtually no control over their political lives, and when we would all cling to superstitions? Yes, Sagan did predict just that. The screenshot you may have seen floating around social media is real. And plenty of people are worried that Carl was talking about our era.
