Neutrinos Didn't Break Light Speed
When news hit the press that some tiny bits of matter traveled faster than light speed, scientists decried the results and the public erupted in speculation. Is that good science?
What's the Latest Development?
Ever since the European Organization for Nuclear Research went public with data suggesting that small bits of matter called neutrinos traveled faster than the speed of light, scientists have been incredulous and the public has spoken of the fall of Einstein, whose general theory of relativity prohibits matter from breaking light speed. The results, however, are almost certainly faulty. Fermilab physicist Joseph Lykken says the experiment was "a pretty messy way to try to test a fundamental property."
What's the Big Idea?
Was it right for the physics lab to go public with the research results before the experiment was peer reviewed? Does keeping scientific data from the public constitute censorship? "When dealing with science and the public, a certain degree of filtering needs to be applied and the whole scientific process to publication needs to be followed through," says science writer Ian O'Neill. As far as the media is concerned, he says, any scientific theory is a good theory as long as it makes a good story.
What can 3D printing do for medicine? The "sky is the limit," says Northwell Health researcher Dr. Todd Goldstein.
- Medical professionals are currently using 3D printers to create prosthetics and patient-specific organ models that doctors can use to prepare for surgery.
- Eventually, scientists hope to print patient-specific organs that can be transplanted safely into the human body.
- Northwell Health, New York State's largest health care provider, is pioneering 3D printing in medicine in three key ways.
- In some fundamental ways, humans haven't changed all that much since the days when we were sitting around communal fires, telling tales.
- Although we don't always recognize them as such, stories, symbols, and rituals still have tremendous, primal power to move us and shape our lives.
- This is no less true in the workplace than it is in our personal lives.
One of Stephen Hawking's predictions seems to have been borne out in a man-made "black hole".
- Stephen Hawking predicted virtual particles splitting in two from the gravitational pull of black holes.
- Black holes, he also said, would eventually evaporate due to the absorption of negatively charged virtual particles.
- A scientist has built a black hole analogue based on sound instead of light.
- The word "creative" is sometimes waved around like a badge of honor. We speak of creativity in hushed tones, as the special province of the "talented". In reality, the creative process is messy, open, and vulnerable.
- For this reason, creativity is often at its best in a group setting like brainstorming. But in order to work, the group creative process needs to be led by someone who understands it.
- This sense of deep trust—that no idea is too silly, that every creative impulse is worth voicing and considering—is essential to producing great work.
