Driverless Cars Could Save Us from Ourselves (and Also from Each Other)
Researchers predict the benefits of driverless taxis on the environment, and the outlook is good.

Driverless cars would be a great benefit to mankind as well as the environment. Firstly, it removes the human element that tends to be the major cause behind traffic accidents (around 90 percent) and, second, it would be a boon for the environment, according to a recent study published in Nature Climate Change.
The new study estimates that by 2030, greenhouse gas emissions could be cut by 87 to 94 percent per mile with autonomous taxis. Even if we're all driving hybrid cars by then, researchers estimate that the switch could still reduce emissions dramatically.
Lead author Jeffery Greenblatt, a staff scientist at Lawrence Berkeley National Laboratory in California, said in a press release:
“When we first started looking at autonomous vehicles, we found that, of all the variables we could consider, the use of autonomous vehicles as part of a shared transit system seemed to be the biggest lever that pointed to lower energy use per mile.”
The researchers are able to give such stellar projections for driverless taxis because of their numerous capabilities. In the end, they found it really is the little things that add up to reducing waste. They can be tailored to your ride — for instance, sending a smaller passenger car if only one person needs a lift or a larger car to accommodate more people, and charting the most optimal route. Autonomous taxis would also eliminate the stop-and-go time compared to normal taxis (if you've ever ridden in one in NYC, you know what I mean); less idling and more driving means more miles with less waste.
However, it has yet to be seen if people will be willing to adopt driverless cars — let alone driverless taxis. But the research seems to show that the benefits could be huge.
"We are not predicting that these things will take over. We’re asking if [they do], what will be the environmental implications?"

It's a development that could one day lead to much better treatments for osteoporosis, joint damage, and bone fractures.
- Scientists have isolated skeletal stem cells in adult and fetal bones for the first time.
- These cells could one day help treat damaged bone and cartilage.
- The team was able to grow skeletal stem cells from cells found within liposuctioned fat.
Gut bacteria play an important role in how you feel and think and how well your body fights off disease. New research shows that exercise can give your gut bacteria a boost.
- Two studies from the University of Illinois show that gut bacteria can be changed by exercise alone.
- Our understanding of how gut bacteria impacts our overall health is an emerging field, and this research sheds light on the many different ways exercise affects your body.
- Exercising to improve your gut bacteria will prevent diseases and encourage brain health.
A groundbreaking new study shows that octopuses seemed to exhibit uncharacteristically social behavior when given MDMA, the psychedelic drug commonly known as ecstasy.
- Octopuses, like humans, have genes that seem to code for serotonin transporters.
- Scientists gave MDMA to octopuses to see whether those genes translated into a binding site for serotonin, which regulates emotions and behavior in humans
- Octopuses, which are typically asocial creatures, seem to get friendlier while on MDMA, suggesting humans have more in common with the strange invertebrates than previously thought
