Neuroscientists have sought to better understand brain function but lacked the capability to observe neuronal activity deep within the brain. Scientists have applied rational molecular engineering to develop photoacoustic probes that can be used deep within brain tissue to label and visualize neurons. This imaging approach expands significantly on what neuroscientists have been able to see with conventional light microscopy, offering the potential to report on deep neuron activity and better understand brain function.

Scientists have learned that children find it hard to focus on a task, and often take in information that won't help them complete their assignment. But the question is, why? In a new study, researchers found that this 'distributed attention' wasn't because children's brains weren't mature enough to understand the task or pay attention, and it wasn't because they were easily distracted and lacked the control to focus. It now appears that kids distribute their attention broadly either out of simple curiosity or because their working memory isn't developed enough to complete a task without 'over exploring.'

Researchers discovered that treating pancreatic cancer with a common chemotherapy drug makes immunotherapy more effective. Folinic acid elevates levels of two anti-cancer immune molecules within pancreatic tumors: natural killer T cells and type-I interferons. In mice, this led to a more effective immune response, slower tumor growth, and longer survival.

New research has uncovered a series of mutations in the SARS-CoV-2 spike protein that enhanced the virus' ability to infect the brains of mice. The findings may help scientists understand its neurological symptoms and the mystery of 'long COVID,' and they could one day even lead to specific treatments to protect and clear the virus from the brain.
