New research by Janelia scientists and collaborators at the University of North Carolina at Chapel Hill shows how a cluster of neurons in the fruit fly brain transforms memories about past rewards into actions, helping the fly navigate to find food. The findings are published in the journal eLife.
turn into the wind, or upwind, to locate the source of attractive odors. The fly's olfactory system detects and senses odors carried by the wind, guiding the fly to the reward.
New research identifies neurons in the fly brain that control upwind steering. When the neurons are activated , the flies turn toward the wind and walk upwind. Credit:In the fly, a brain region called the mushroom body processes and integrates olfactory information.

Researchers find new mechanisms that cause blindness and open the door to new treatmentsThere are still many enigmas about the mechanism of action of the CERKL gene, which causes retinitis pigmentosa and other hereditary vision diseases. Now, a team from the University of Barcelona has described how the lack of the CERKL gene alters the ability of retinal cells to fight oxidative stress generated by light and triggers cell death mechanisms that cause blindness.

Researchers discover possible new treatment for triple-negative breast cancerZachary Schug, Ph.D., assistant professor in the Molecular and Cellular Oncogenesis Program of the Ellen and Ronald Caplan Cancer Center at The Wistar Institute, has published a new paper in the journal Nature Cancer. Schug's paper, titled 'Acetate acts as a metabolic immunomodulator by bolstering T-cell effector function and potentiating antitumor immunity in breast cancer,' demonstrates a double-acting mechanism for fighting a particularly aggressive, difficult-to-treat form of breast cancer. Schug's research shows how silencing a certain gene, ACSS2, may improve existing treatments for patients.

Researchers identify new blood marker for dopamine system damageThe marker in question is called DOPA decarboxylase (DCC). In the current study, DCC was found to be elevated in individuals with Parkinson's disease as well as in people with other diseases that result in dopamine deficiency in the brain. However, the marker was normal in other brain diseases such as Alzheimer's disease. The researchers even noticed that DCC was elevated in individuals with Parkinson's many years before they developed any symptoms.
