Early Focus: Research increasingly suggests that Alzheimer’s disease damages the brain years before symptoms appear, raising the possibility that treatments should be focused on this early phase if there’s a hope of slowing or reversing the disease, the WSJ reports. That’s why Pfizer, Johnson & Johnson and Bristol-Myers Squibb are looking to treat patients with signs of milder memory loss, the paper says.
Hackable Devices: Security researcher Jay Radcliffe says insulin pumps and blood-sugar monitors can be hacked, too, raising the question of how to keep high-tech medical devices secure, the Associated Press reports. Many devices contain wireless chips, but most are too small to contain encryption technology, the AP says.
Lab-Grown Sperm: Mouse sperm created from embryonic stem cells in a lab was used to successfully fertilize mouse eggs and produce apparently normal offspring, the WSJ reports. Experts call the research, published in Cell, a breakthrough but caution it may not translate to humans.
Lower Costs: Premiums for Medicare prescription-drug coverage will edge down next year to an average of about $30 a month from $30.76 this year, the Los Angeles Times reports. Increased use of generic medications and competition are behind the decline, according to the Department of Health and Human Services.
