- Sniffing out the brain's smelling power
Since their discovery over 100 years ago, neurons in the brain's olfactory bulb, called tufted cells, have been difficult to study. By leveraging new technology, neuroscientists were able to precisely dissect the neural activity of these tufted cells for the first time. They discovered the tufted cells were better at recognizing smells than mitral cells, their neighboring neurons in the olfactory bulb. Their findings offer new explanations for how the brain processes sensory information.

- New model captures the erratic speed of DNA copying proteins in bacteria
A new study has revealed that certain locations of DNA are copied faster than others, which could also have an effect on mutation rate.

- Brain injury in preemies may be treatable even well after birth
Brain injury in extremely premature babies may be treatable even well after birth, new research finds. Over a third of cases of cerebral palsy are still linked to being born extremely prematurely.

- Seeing antibiotics in action inside a pathogenic bacterium
New research shows at atomic detail how antibiotics affect the process of protein production inside bacteria. The study uses cryo-electron tomography to observe the dynamics of the translation machinery in Mycoplasma pneumoniae, tiny parasitic bacteria that cause atypical pneumonia in humans.

- Rate of food insecurity skyrockets for Americans with cardiovascular disease
The number of Americans with cardiovascular disease who are food insecure -- having limited or uncertain access to adequate food -- has more than doubled over the last 20 years, a national study finds. Adults with cardiovascular disease were more than two times likely to be food insecure than those without the cardiovascular disease.

- High blood pressure speeds up mental decline, but does not fully explain dementia disparities
High blood pressure means faster slide into signs of dementia or Alzheimer's, but does not explain the overall disparity between Hispanic/Latino people and non-Hispanic people in dementia risk.

- Newly discovered protein could be used to produce life-saving antifungals
Researchers have discovered a protein that is responsible for controlling cell growth in yeasts. Since humans and yeasts have remarkably similar cellular mechanisms, teasing out the differences presents drug developers with new targets for treatments.

- With fractured genomes, Alzheimer's neurons call for help
Ailing neurons plagued with an accumulation of double-strand breaks in their DNA may instigate an inflammatory response from the brain's microglia immune cells, a new study shows.

- Brain development of the preterm baby is improved by supporting emotional connection with the parent
Supporting emotional connection between a premature baby and mother during the intensive care unit treatment effectively improves the baby's brain development. The effects are clearly visible in the baby's brain network function and later neurocognitive development.

- Robotic drug capsule can deliver drugs to gut
A new drug capsule can help large proteins such as insulin and small-molecule drugs be absorbed in the digestive tract. The capsule has a robotic cap that spins and tunnels through the mucus barrier when it reaches the small intestine, allowing drugs carried by the capsule to pass into cells lining the intestine.
