Low levels of a substance, acetyl-L-carnitine, in the blood are associated with depression. Could this "mood mirror" be a cure for the blues?

How our brains blend cues from multiple senses to estimate our speed and position in space depends on where we are and how fast we seem to be moving.

What if you could stitch together single cells any way you wanted to? Potential medical and even industrial applications abound.

Antiretroviral therapy, a breakthrough treatment for HIV infection, suppresses the levels of circulating HIV viral particles in the blood. When it works, cancer rates drop, according to a new study. Still, even when the therapy is successful, HIV-positive individuals retain elevated rates of cancer.

A hitherto unheralded set of telltale enzymes may prove to be perfect targets for shooting down a gang of nasty bacterial pathogens collectively called S. aureus.

The discovery, in mice, of a pair of nerve clusters regulating fearful versus bold responses to a visual threat could help people with excessive anxiety, phobias or post-traumatic stress disorder lead more normal lives.

What makes breathing possible is a thin coating of a soaplike film, or surfactant, that lowers the tension of the lung’s inner surface. Premature babies and adults with lung injuries are short on surfactant, and replacing it has been prohibitively pricey. That may be about to change.

Older people are more susceptible to infection, cancer, and autoimmunity than younger people. This may be the result of our immune cells' receiving increasingly random marching orders as we age.

In an interview in the journal Neuron, Stanford's Rob Malenka holds forth on a wide range of subjects stretching from reflections on his own career trajectory to his approach to boosting those of his trainees to the future of neuroscience itself.
