Scientists have successfully implanted false memories into mice. The researches are excited at prospect of applying the same processes to human beings, which they say holds promise for treating emotional problems such as post-traumatic stress disorder. Read about the experiment after the jump, and then I want to pose some questions. [Read more…]
It has long been said that dogs can only see in black and white. But scientists have now proven that they do, in fact, perceive colors, though in a slightly different spectrum from humans, and that they derive information from the color of objects that they see. [Read more…]
A couple of years ago, I wrote a post in praise of the naked mole rat, an exceedingly odd little creature with seemingly super powers when it comes to health and longevity. Well, scientists have recently discovered why these things don’t get cancer, something that could lead to treatments in human beings. [Read more…]
Back in 2007, about three different servers ago when this blog was with World, I wrote a post entitled The Rapture of the Bees. Honeybees were disappearing, which is a major concern, since they are so important in the pollination of crops. Since then, I’ve read several pieces that purportedly solved the mystery of why that’s happening, but I guess there is still controversy over the causes, and the problem remains. Thanks to Pete Muller, who sent me an account of a “Bee Summit” sponsored by pesticide-maker Monsanto.
Some are blaming pesticides for the die-off of bees, while others are blaming a kind of mite that preys on bees and that presumably could be controlled by. . . pesticides. Anyone want to guess what the diagnosis will be from the Monsanto summit? Or from environmentalists? Notice how science, though supposedly objective, is not free from conclusion-shaping presuppositions. [Read more…]
At least in deer mice. Scientists have known that motherhood makes the female rodents smarter, better foragers, braver, and more level-headed. A researcher has found the same effect in father mice. In fact, something similar happens when male mice are exposed to baby mice, even when they aren’t the biological father. All of this has been traced to specific changes in the mice brains. This has not been proven, of course, for human beings, but many men can probably relate to this.
Details after the jump. Have any of you been changed by fatherhood? Or exposure to children? [Read more…]
