Researchers have found that dopamine neurons in the brain can represent the decision-making process when making economic choices. As monkeys contemplated whether or not to choose an item, a subset of dopamine neurons transitioned from indicating the item's value to indicating the monkey's ultimate decision. Encoding of the decision into these dopamine neurons happened earlier than it did in other parts of the brain related to economic decision-making.

With the rise of globalization, geographic borders are becoming less relevant for making charitable donations, which means nonprofits and charities can make more effective pitches to donors by emphasizing higher-level concepts such as morality and idealistic values, said Carlos Torelli, a professor of business administration and the James F. Towey Faculty Fellow at Illinois.

Scientists have engineered natural killer immune cells that not only kill head and neck tumor cells in mice but also reduce the immune-suppressing myeloid cells that allow tumors to evade the immune response.

While researchers have previously identified brain structural signatures associated with individual neurological diseases using techniques such as magnetic resonance imaging (MRI), a team of scientists has now compared data from multiple studies to find brain structural abnormalities shared between four different neuropsychiatric conditions. The researchers also found brain signatures that were unique to individual conditions.

The human immune system is a finely-tuned machine, balancing when to release a cellular army to deal with pathogens, with when to rein in that army, stopping an onslaught from attacking the body itself. Now, researchers have discovered a way to control regulatory T cells, immune cells that act as a cease-fire signal, telling the immune system when to stand down.

In experiments in rats and mice, two scientists -- an engineer and an ophthalmologist -- report the successful use of nanoparticles to deliver gene therapy for blinding eye disease. A uniquely engineered large molecule allows researchers to compact large bundles of therapeutic DNA to be delivered into the cells of the eye.
