"Usually at this point in a drug's development, we are happy to see improvement in one of the outcome measures," Doody said. "We saw improvement in all five."
Some participants complained of occasional dry mouth, but no one opted out of the study because of the side effects.
"As we continue research, we hope to replicate these results," Doody said. "My belief is that this drug will turn out to be useful for Alzheimer's disease, regardless of the stage of the disease."

Bees Go 'Off-color' When They Are Sickly
Lecturer in Animal Biology at the University of Leicester Dr. Eamonn Mallon, who lead the research group, said: "Disease can influence different behaviours including foraging, mate choice, and predator avoidance. Several recent papers have shown reduced learning abilities in infected insects. However, it is difficult to separate the effects of the immune response from the direct effects of the parasite. That was the purpose of our study"
Bees were divided into a control group and a group that were injected with lipopolysaccharide, a substance that stimulated an immune response without a need for the bee to be infected with a disease. Bees were offered the choice of blue and yellow artificial flowers only one type of which contained sugar water. An individual's flight was recorded over ninety visits to these flowers. Eventually the bees spent almost all of their time going to the rewarding flowers, but it took the immune stimulated bees longer to reach this point.

Deep Down, We Can’t Fool Even Ourselves
You show up for an experiment and are told that you and a person arriving later will each have to do a different task on a computer. One job involves a fairly easy hunt through photos that will take just 10 minutes. The other task is a more tedious exercise in mental geometry that takes 45 minutes.
You get to decide how to divvy up the chores: either let a computer assign the tasks randomly, or make the assignments yourself. Either way, the other person will not know you had anything to do with the assignments.
Now, what is the fair way to divvy up the chores?
When the researchers posed this question in the abstract to people who were not involved in the tasks, everyone gave the same answer: It would be unfair to give yourself the easy job.
But when the researchers actually put another group of people in this situation, more than three-quarters of them took the easy job. Then, under subsequent questioning, they gave themselves high marks for acting fairly. The researchers call this moral hypocrisy because the people were absolving themselves of violating a widely held standard of fairness (even though they themselves hadn’t explicitly endorsed that standard beforehand).
The more interesting question is how presidential candidates, and their supporters, turn into hypocrites. It has been demonstrated repeatedly in experiments that humans are remarkably sensitive to unfairness. We’ve survived as social animals because we are so good at spotting selfishness and punishing antisocial behavior.
So how we do violate our own moral code? Does our gut instinct for self-preservation override our moral reasoning? Do we use our powers of rationality to override our moral instinct?
“The question here,” Dr. DeSteno said, “is whether we’re designed at heart to be fair or selfish.”
Numerology
Andrew Hodges, a fellow at Oxford and the author of the lively new book “One to Nine,” would have been horrified, but not surprised. My cousin, in his view, is a victim of the pedagogical tradition that presents math as an eternally fixed array of computations, to be memorized and repeatedly executed without motivation or explanation. The result, he writes, is a “legacy of fear and anxiety generated by schools, which leaves most of their victims with a lifetime of mumbling apologetically about ‘my worst subject.’”
“One to Nine” offers a different model for teaching math — discursive rather than linear, topical rather than abstract and remote, and, above all, manically energetic rather than repetitive and plodding. The book is composed of nine chapters, each focused — very, very softly focused — on one of the first nine natural numbers. Chapter Four, for instance, starts out with the observation that four is a perfect square, and from there skips along to the construction of Latin squares, the irrationality of the square root of two, the definition of the logarithm (whose relation to “four” never comes entirely clear), complex numbers, and the even more exotic quaternions (a number system in which “numbers” are actually strings of four integers, and the product of two numbers depends on the order in which you multiply them!), the theory of four-dimensional spacetime and Einstein’s equation E=mc2 (squares again) before finishing with a short and speculative account of the theory of twistors, one of many competing candidates for the universe’s underlying geometry.
