The Deeper Code

Researchers are attempting to "define a second genetic code: one that predicts how segments of messenger RNA transcribed from a given gene can be mixed and matched."

"Between DNA and proteins comes RNA, and an expanding realm of complexity," writes Heidi Ledford. "RNA is a shape-shifter, sometimes carrying genetic messages and sometimes regulating them, adopting a multitude of structures that can affect its function." Researchers are attempting to "define a second genetic code: one that predicts how segments of messenger RNA transcribed from a given gene can be mixed and matched to yield multiple products in different tissues, a process called alternative splicing."

Study: 50% of people pursuing science careers in academia will drop out after 5 years

That's a sharp increase from the 1960s when it took the same share of scientists an average of 35 years to drop out of academia.

Surprising Science
  • The study tracked the careers of more than 100,000 scientists over 50 years.
  • The results showed career lifespans are shrinking, and fewer scientists are getting credited as the lead author on scientific papers.
  • Scientists are still pursuing careers in the private sector, however there are key differences between research conducted in academia and industry.

The silent Chinese propaganda in Hollywood films

China's rise has necessitated a global PR push. It includes influencing how the movies you watch depict China.

Politics & Current Affairs
  • China will soon overtake the U.S. as the world's largest market for films, and it is using that fact to influence how it is depicted by Hollywood.
  • While Chinese investors have been interested in buying shares of studios for a while, the real power lies in deciding which movies get into China at all.
  • The influence is often subtle, but may have already derailed a few careers in the name of politics.

New ‘microneedle patch’ could help heart attack patients regrow tissue

The bold technique involves surgically implanting a so-called microneedle patch directly onto the heart.

Surprising Science
  • Heart attacks leave scar tissue on the heart, which can reduce the organ's ability to pump blood throughout the body.
  • The microneedle patch aims to deliver therapeutic cells directly to the damaged tissue.
  • It hasn't been tested on humans yet, but the method has shown promising signs in research on animals.
