Carl Zimmer has an interesting article about attempts to estimate how many cells the average human body contains. It depends on how you do it and previous estimates over the past few centuries have ranged widely from two billion to 200 million trillion cells. [Read more…]
Developments in robotics that mimic living things are quite amazing. Here’s one robot designed to look and work like a pack mule that can go over rough terrain. [Read more…]
In a startling display of good sense, the ban on Chinese scientists attending a conference on the Kepler space telescope program at a NASA site has been reversed, after many non-Chinese scientists started talking about boycotting the event altogether, since even Chinese graduate students and post docs working in the US with US scientists would be barred.
