How Single Cells Evolved

The question of how single celled organisms evolved into more dynamic multicellular ones is difficult to answer, but scientists in Tennessee believe genetic on/off switches provide a clue.

The question of how single celled organisms evolved into more dynamic multicellular ones is difficult to answer, but scientists in Tennessee believe genetic on/off switches provide a clue. "How colonies of single cells evolved into multicellular organisms has long been a puzzle. The process requires single cells to band together and divide the tasks of life. To do so, some cells must give up their ability to reproduce," says the New Scientist. "To investigate, Sergey Gavrilets of the University of Tennessee in Knoxville created a mathematical model describing a colony of identical cells able to survive and reproduce. He assumed trade-offs between the tasks: being better at reproducing made cells worse at survival, and vice versa. In the simplest case, the colony evolved into organisms made of cells that were mediocre at both tasks."

Biohacking: Why I'll live to be 180 years old

From computer hacking to biohacking, Dave Asprey has embarked on a quest to reverse the aging process.

  • As a teenager, founder of Bulletproof, Dave Asprey, began experiencing health issues that typically plague older adults.
  • After surrounding himself with anti-aging researchers and scientists, he discovered the tools of biohacking could dramatically change his life and improve his health.
  • He's now confident he'll live to at least 180 years old. "It turns out that those tools that make older people young make younger people kick ass," he says.

Surprising Science
  • A new report calculated how much electricity Europe could generate if it built onshore wind farms on all of its exploitable land.
  • The results indicated that European onshore wind farms could supply the whole world with electricity from now until 2050.
  • Wind farms come with a few complications, but the researchers noted that their study was meant to highlight the untapped potential of the renewable energy source in Europe.
