As UberX and Lyft Get Cheaper, Should You Sell Your Car?
The new prices are an experiment in stoking demand. If the cost of a single ride drops far enough, people may begin abandoning their cars for their daily commute or midday errand.
What's the Latest?
Two industry disruptors, Uber and Lyft, are changing the way people commute in urban centers. This summer, the companies are rolling out new pricing schemes meant to outfox established taxi companies. "The price cut amounts to 20 percent in New York and 25 percent in San Francisco and Los Angeles. By the company’s math, that leaves the price of a ride lower than that of a taxi in New York, and in other cities the price is now significantly lower." In some markets, Uber is forsaking its 20 percent commission to keep prices low. But why would a company purposefully take a loss on each transaction?
What's the Big Idea?
The new prices are an experiment in stoking demand. If the cost of a single ride drops far enough, people may begin abandoning their cars for their daily commute or midday errand. The effect may be a low-margin business but one with a guaranteed demand for the foreseeable future. "The whole point of price cuts is to get UberX pricing below the cost of owning a car," said Uber’s chief executive, Travis Kalanick. "Let’s say you take three or four trips a day on average. If we can get the price of UberX low enough, we can get to where it’s cheaper to take Uber than to own a car."

Physicist Frank Wilczek proposes new methods of searching for extraterrestrial life.
- Nobel Prize-winning physicist Frank Wilczek thinks we are not searching for aliens correctly.
- Instead of sending out and listening for signals, he proposes two new methods of looking for extraterrestrials.
- Spotting anomalies in planet temperature and atmosphere could yield clues of alien life, says the physicist.
1. Atmosphere chemistry<p>Like we found out with our own effect on the Earth's atmosphere, making a <a href="https://ozonewatch.gsfc.nasa.gov/facts/hole_SH.html" target="_blank">hole in the ozone layer</a>, the gases around a planet can be impacted by its inhabitants. "Atmospheres are especially significant in the search for alien life," <a href="https://www.wsj.com/articles/looking-for-signs-of-alien-technology-11581605907" target="_blank">writes Wilczek</a> "because they might be affected by biological processes, the way that photosynthesis on Earth produces nearly all of our planet's atmospheric oxygen."</p><p>But while astrobiology can provide invaluable clues, so can looking for the signs of alien technology, which can also be manifested in the atmosphere. An advanced alien civilization might be colonizing other planets, turning their atmospheres to resemble the home planets. This makes sense considering our own plans to terraform other planets like Mars to allow us to breathe there. Elon Musk even <a href="https://www.space.com/elon-musk-serious-nuke-mars-terraforming.html" target="_blank">wants to nuke the red planet.</a></p>
The Most Beautiful Equation: How Wilczek Got His Nobel<div class="rm-shortcode" data-media_id="ijBZzuI2" data-player_id="FvQKszTI" data-rm-shortcode-id="061a3de613c45f42b05432a2949e7caa"> <div id="botr_ijBZzuI2_FvQKszTI_div" class="jwplayer-media" data-jwplayer-video-src="https://content.jwplatform.com/players/ijBZzuI2-FvQKszTI.js"> <img src="https://cdn.jwplayer.com/thumbs/ijBZzuI2-1920.jpg" class="jwplayer-media-preview" /> </div> <script src="https://content.jwplatform.com/players/ijBZzuI2-FvQKszTI.js"></script> </div>
2. Planet temperatures<p>Wilczek also floats another idea - what if an alien civilization created a greenhouse effect to raise the temperature of a planet? For example, if extraterrestrials were currently researching Earth, they would likely notice the increased levels of carbon dioxide that are <a href="https://www.epa.gov/ghgemissions/overview-greenhouse-gases" target="_blank">heating up</a> our atmosphere. Similarly, we can looks for such signs around the exoplanets.</p><p>An advanced civilization might also be heating up planets to raise their temperatures to uncover resources and make them more habitable. Unfreezing water might be one great reason to turn up the thermostat. </p><p>Unusually high temperatures can also be caused by alien manufacturing and the use of artificial energy sources like nuclear fission or fusion, suggests the scientist. Structures like the hypothetical <a href="https://bigthink.com/paul-ratner/this-mind-bending-scale-predicts-the-power-of-advanced-civilizations" target="_self">Dyson spheres</a>, which could be used to harvest energy from stars, can be particularly noticeable. </p>

As patients approached death, many had dreams and visions of deceased loved ones.
One of the most devastating elements of the coronavirus pandemic has been the inability to personally care for loved ones who have fallen ill.
Research reveals a new evolutionary feature that separates humans from other primates.

Being skeptical isn't just about being contrarian. It's about asking the right questions of ourselves and others to gain understanding.
