Researchers successfully sent a simulated elementary particle back in time

Don't start investing in flux capacitors just yet, though.

  • The second law of thermodynamics states that order always moves to disorder, which we experience as an arrow of time.
  • Scientists used a quantum computer to show that time travel is theoretically possible by reverting a simulated particle from an entropic to a more orderly state.
  • While Einstein's general theory of relativity permits time travel, the means to achieve it remain improbable in nature.

Great risk for great gain: Immigrants and innovators are psychologically the same

Don't denigrate immigrants, says Jared Diamond. You are one.

  • Every American, without exception, is an immigrant. Native Americans immigrated 13,000 years ago, and everybody else has immigrated within the last 400 years.
  • The decision to emigrate is made by people who are healthy, strong, willing to undertake risks, and face the unknown. Those are also essential qualities for innovating.
  • It's no coincidence that the great majority of American Nobel Prize winners are either first-generation immigrants or the children of first-generation immigrants.

  • Mother's Day is Sunday, May 12.
  • Philip Seymour Hoffman, Jane Goodall, and Elon Musk all received extraordinary support from their mothers.
  • Without this support, these innovators' careers probably would've turned out much differently.

  • An Oregon company provided falsified tests to a NASA rocket builder for almost two decades.
  • The company is now liable for $46 million in payments and the lab manager went to prison.
  • NASA can't test every single component itself, making it important the supply chain is protected.

AI is turning thoughts into speech. Should we be concerned?

A new study highlights a fascinating application of AI, though other uses are more troubling.

  • Recent research in epilepsy patients has provided a breakthrough in AI-enabled speech recognition technology.
  • Soon researchers believe such an application will translate brain waves into speech.
  • The moral dangers of AI, especially concerning privacy, continue to be an issue.
