Can training improve memory, thinking abilities in older adults with cognitive impairment?
A new, first-of-its-kind study was designed to assess whether cognitive training, a medication-free treatment, could improve MCI. Studies show that activities that stimulate your brain, such as cognitive training, can protect against a decline in your mental abilities. Even older adults who have MCI can still learn and use new mental skills.

T-cells engineered to outsmart tumors induce clinical responses in relapsed Hodgkin lymphoma
A research team has validated a way to outfox tumors. They engineered T-cells, essential players in the body's own immune system, to strip tumors of their self-preservation skill and were able to hold Hodgkin lymphoma at bay in patients with relapsed disease for more than four years.

Are amoebae safe harbors for plague?
Amoebae, single-celled organisms common in soil, water and grade-school science classrooms, may play a key role in the survival and spread of deadly plague bacteria. New research shows that plague bacteria, Yersinia pestis, not only survive, but thrive and replicate once ingested by an amoeba. The discovery could help scientists understand why plague outbreaks can smolder, stay dormant for years, and re-emerge with a vengeance.

Memory loss from West Nile virus may be preventable
More than 10,000 people in the United States are living with memory loss and other persistent neurological problems that occur after West Nile virus infects the brain. Now, a new study in mice suggests that such ongoing neurological deficits may be due to unresolved inflammation that hinders the brain's ability to repair damaged neurons and grow new ones. When the inflammation was reduced by treatment with an arthritis drug, the animals' ability to learn and remember remained sharp after West Nile disease.

Bariatric surgery prolongs lifespan in obese
Obese, middle-age men and women who had bariatric surgery have half the death rate of those who had traditional medical treatment over a 10-year period, reports a study that answers questions about the long-term risk of the surgery. Previous studies looking at this question were indefinite because follow-up data was limited due to high costs and patients dropping out.

In chronic disease care, family helpers are key, but feel left out
People with diabetes, heart failure and other chronic diseases often live independent lives, without a traditional caregiver. But many have a family member or friend who plays a key supporting role in their health care.

Improving stroke treatment through machine learning
Methods from optogenetics and machine learning should help improve treatment options for stroke patients. Researchers have now developed a computer vision technique to analyze the changes in motor skills that result from targeted stimulation of healthy areas of the brain.
