Let's just say it's a good thing this breakthrough didn't come around when I was in my early twenties, or I may have been tempted to spend a little more time at my favorite neighborhood watering hole.

Using a process called decellularization, the team rinsed real livers from an unspecified animal with detergent, stripping them of all their cells and leaving only … Read more

The Electronic Frontier Foundation publishes Tor, a free suite of Internet communications and security utilities.

Tor's developers stress the importance of understanding what Tor does and doesn't do; it stands not … Read more

Things for iPhone is a well-designed, easy-to-use, highly scalable task-management app for the iPhone and iPod Touch, and it's even better when paired with the Mac desktop app of the same name.

Tasks are collected under Projects (sets of smaller subtasks), Areas (areas of responsibility, such as work or family), and an Inbox "waiting area" for unsorted tasks.

Things also has a handy Today list (which also … Read more

There's no gentle way to put it. Chronic kidney failure is ugly and often deadly, and more people in the States are suffering from it every year, with increasing rates of diabetes and hypertension contributing to the problem.

What's more, the treatment that keeps many waiting for kidney transplants alive--dialysis--involves several sessions per week, at several hours per session, during which blood pumps through an external circuit for filtration to replace just 13 percent of kidney function, leaving many patients exhausted both physically and financially.

(The U.S. Renal Data System estimates that dialysis costs roughly $… Read more
