Scientists create a renewable source of cancer-fighting T cells
A study by UCLA researchers is the first to demonstrate a technique for coaxing pluripotent stem cells -- which can give rise to every cell type in the body and which can be grown indefinitely in the lab -- into becoming mature T cells capable of killing tumor cells.

Psychological distress is a risk factor for dementia
A new study suggests that vital exhaustion -- which can be perceived as an indicator of psychological distress -- is a risk factor for future risk of dementia.

Combination therapy treats leishmaniasis, HIV patients
Coinfection with visceral leishmaniasis (VL) and human immunodeficiency virus (HIV) has been observed in at least 35 countries on four continents and requires special case management. Currently, the World Health Organization recommends AmBisome monotherapy for treatment. Now, researchers have showed that a combination therapy of AmBisome and miltefosine is more effective.

New findings reveal surprising role of the cerebellum in reward and social behaviors
A study in rodents found that the brain's cerebellum -- known to play a role in motor coordination -- also helps control the brain's reward circuitry. Researchers found a direct neural connection from the cerebellum to the ventral tegmental area (a brain area long known to be involved in reward processing and encoding). The findings shed light on the brain circuits critical to the affective and social dysfunction seen across multiple psychiatric disorders.

Gene therapy blocks peripheral nerve damage in mice
Scientists have developed a gene therapy that blocks axonal degeneration, preventing axon destruction in mice and suggesting a therapeutic strategy that could help prevent the loss of peripheral nerves in multiple conditions.

Wired for obesity
Researchers have discovered a set of genes that help to establish brain connections governing body weight.

Blocking hormone uptake burns more fat
A newly discovered regulatory mechanism helps the body control the rate of fat metabolism, according to a new study. The finding may lead to new drugs to help burn stored fat and reduce weight.

Brain cells that make pain unpleasant
If you step on a tack, neurons in your brain will register two things: that there's a piercing physical sensation in your foot, and that it's not pleasant. Now, a team of scientists has identified a bundle of brain cells in mice responsible for the latter -- that is, the negative emotions of pain.

Stress fracture? Your foot hitting pavement wasn't the main problem
It starts as a persistent and irritating pain in the foot or lower leg, then it gets more intense, maybe with swelling, and soon a runner knows she's being sidelined by one of the most common running injuries: a stress fracture. These tiny cracks in the bone can halt training for months or even end a sports season. A segment of the multibillion-dollar wearables industry aims to save potential victims from this fate, but an engineering professor found a major problem: the devices are measuring the wrong thing.

New hope for stem cell approach to treating diabetes
Researchers have tweaked the recipe for coaxing human stem cells into insulin-secreting beta cells and shown that the resulting cells are more responsive to fluctuating glucose levels in the blood.
