Remember last year’s death-predicting longevity-gene study, estimating who is likely to live to 100 and who will not be so lucky? Well, the authors of the study have retracted their paper. But there’s a catch: They claim they were still right.
Though many scientists hailed the results last week, some geneticists expressed doubt about a study that linked several genes to extreme old age. Now, at least one expert is saying the DNA analysis chips used to conduct the study may have led to faulty results.
The study authors defend their work, but said in a statement Wednesday afternoon that they were re-examining their analysis.
A study finds that visits from robotic pets provide the same health benefits to the elderly as ones from flesh-and-blood pooches

It turns out playing with a robot pet can be just as soothing as interacting with the real thing. Saint Louis University researchers conducted a study in three U.S. nursing homes to see how elderly people would respond to Sonys Aibo, the robo-dog, versus a flesh-and-blood mutt. The subjects were divided into three groups. One got regular visits from the mutt, the second played with Aibo and the third was deprived of both.
