Problems with the Standard Model Higgs | Azimuth
Here is a conversation I had with Scott Aaronson. It started on his blog, in a discussion about 'fine-tuning'. Some say the Standard Model of particle physics can't be the whole story, because in this theory you need to fine-tune the fundamental constants to keep the Higgs mass from becoming huge. Others say this argument…

Calorie restriction and longevity: Monkey study shows hunger doesn’t increase longevity, but type of food does.

We find that the effort researchers waste in writing proposals may be comparable to the total scientific value of the research that the funding supports, especially when only a few proposals can be funded. Moreover, when professional pressures motivate investigators to seek funding for reasons that extend beyond the value of the proposed science (e.g., promotion, prestige), the entire program can actually hamper scientific progress when the number of awards is small. We suggest that lost efficie...
