Researchers in Seattle have created a public observatory for studying the visual circuitry in a mouse's brain. Among the attractions: watching 18,000 neurons respond to Orson Welles'
Touch of Evil.

Using gold, silicone and heart cells from a rat, scientists have made a tiny artificial stingray. The engineering involved in propelling it could help make a heart that's more than a mechanical pump.

In mice, monkeys and people, exercise releases a protein called cathepsin B. And as blood and brain levels of this protein rise, memory gets better. But the protein has a dark side, too.

A survey of more than 3,500 people caring for family members with dementia finds that many are spending down personal savings and cutting into their own basic needs to meet their loved one's expenses.

The sighs we notice usually accompany emotions like relief or discontent. But our brains are programmed to make us heave an unconscious sigh every five minutes or so — no matter how we feel.
"Sighing is vital to maintain lung function," says
Jack Feldman, a brain scientist at UCLA. ...
