Kathleen E. Breeden ’09 is a prospective history and literature concentrator in Hollis Hall, where she’s petitioned for a resident cat to assist in the ongoing war against mice. This Kentuckian enjoys making tea, building shrines to C.S. Lewis, and pulling all-nighters in Lamont. She swears she won’t procrastinate on drawing submissions, though, so you can look for her cartoon on Thursdays...
...that distinguishes people with high brain reserve from those with low brain reserve. I think that's been part of the problem: we've been looking for a magic bullet." Instead, Valenzuela postulates that mental activity alters the central nervous system in different ways at various levels. Research on mice, he says, shows that a highly stimulating environment increases both the production of new brain and nerve cells and the density of blood vessels around them. A few years ago, Valenzuela headed a project in which a group of elderly Sydney residents had their brains analyzed before and after five...
...higher pH environment of the female cervix. Activated CatSper allow calcium ions to flow into the sperm’s tail. The calcium influx, measurable as an electrical current, alters the way the flagella bends and hyper-activates the tail’s motor proteins. In experiments, mice altered to lack the CatSper protein had weak swimming sperm and were infertile...
...headquarters now holds blood samples from about 100,000 individuals, roughly half of Iceland's adult population. Using those samples, scientists at the company were able to zero in on their new anti-heart-attack compound. It's based on a gene known as LTA4H, first seen in mice, which governs the production of an enzyme called leukotriene A4 hydrolase. The enzyme plays a role in inflammation, a key factor in heart disease, and also encourages the buildup of cholesterol on blood-vessel walls...
...American researchers have created pigs with human blood, sheep with partially human brains, livers, hearts, and of course, the brainy mice. Such experiments are grounded in all kinds of hopes: hope for a way to relieve the heartbreaking shortage of organs for transplant, for example, or for testing new drugs and treatments on a more nearly human animal to better judge what works. Other researchers are introducing animal DNA into human embryos as a kind of marker, to help them understand how disease develops. Some research involves the intentional creation and destruction of human embryos, however, which is controversial...
