AI clinician trained to save humans from sepsis – and, er, let's just say you should stick to your human doctor

RosieRedfield

"...the chances of a patient’s survival was highest where the model was most accurate in its recommendations compared to a real expert."

Reworded: The real patients survived better when their real doctor had done what the model would have recommended.

Corollary: When the real doctor had done something other than what the model would have recommended, the patients did worse.

Doesn't the corollary mean that the model's recommendations were BETTER than the physicians in these cases?

Losing 3.8 kg in 2 weeks is not good nutrition

This is an alarming rate of weight loss, equivalent to what one might expect to see with a severely calorie-restricted diet.

You may be getting enough vitamins and protein, but you're probably only getting only about half of the calories you would normally consume. If you're fat this is probably OK for a little while, but it's certainly not sustainable, especially for anyone who isn't overweight.

Great for the geezers

Ideal for the elderly. Instead of struggling to get the incompetent oldsters off the road, let's just put them in self-driving cars.

Pathogens in space

The research claiming that some bacteria become more virulent in space is just another example of over-hyped NASA astrobiology research; see the RRResearch post here: http://rrresearch.fieldofscience.com/2011/04/do-bacteria-become-superbugs-in-space.html.

Siri gets over her huff, returns useful as ever

For me, Siri is a useful resource, not just a novelty, because her voice recognition is more accurate than my typing.

THE TRUTH on the Californian NASA POISON ALIENS

Researchers think NASA is wrong

I've posted a long critique of the microbiology and molecular biology at http://rrresearch.blogspot.com.

Alex Bradley has provided the chemist's critique over at ScienceBlogs, at http://scienceblogs.com/webeasties/2010/12/guest_post_arsenate-based_dna.php.

We agree that the authors' conclusions and NASA's hype are unfounded.
