Hormone therapy associated with improved cognition

Estrogen has a significant role in overall brain health and cognitive function. That's why so many studies focused on the prevention of cognitive decline consider the effect of reduced estrogen levels during the menopause transition. A new study suggests a cognitive benefit from a longer reproductive window complemented with hormone therapy.

Acceptance and commitment therapy may ease fear of recurrence in cancer survivors

Researchers report that Acceptance and Commitment Therapy (ACT) shows significant promise for treating fear of cancer recurrence in women who have survived breast cancer. Fear that cancer may come back or progress is especially common in breast cancer survivors, with up to 70% reporting that the fear affects their daily life.

Scientists help immune system find hidden cancer cells

Cancer cells are masters at avoiding detection, but a new system can make them stand out from the crowd and help the immune system spot and eliminate tumors that other forms of immunotherapies might miss.

New method visualizes groups of neurons as they compute

Using a fluorescent probe that lights up when brain cells are electrically active, researchers found they can image the activity of many neurons at once, in mice brains. The technique could allow neuroscientists to analyze circuits within the brain and link them to specific behaviors.

'Wild idea' opens possible new frontier for preventing ovarian cancer

A laboratory study offers a new hypothesis about how ovarian cancer forms and suggests how it might be prevented. The study is the first to show that the natural stiffening of the ovaries called fibrosis occurs with age. It also suggests that the diabetes drug metformin may be able to halt this process.

Research maps key signaling pathways linking calcium entry and exit in activated T cells

Like entrance and exit doors on a building, a cell's outer surface has doors -- channels, pumps, and transporters that selectively control what molecules enter or exit. In the immune system, T cells possess unique sets of 'doors', including ones that specialize in calcium ion movement. Now, researchers describe a unique mechanism for coordinating these calcium entrance and exit 'doors' on T cells that helps them carry out their jobs and ensure normal immune function.

How can ultrasonic brain stimulation cure brain diseases?

Scientists found a calcium channel expressed in astrocytes in the brain to be a highly sensitive target for LILFU-induced neuronal activity in the motor cortex, such as tail movement.

Mapping normal breast development to better understand cancer

Breast cancer is one of the most prevalent cancers, and some forms rank among the most difficult to treat. Its various types and involvement of many different cells makes targeting such tumors difficult. Now, researchers have used a state-of-the-art technology to profile each cell during normal breast development in order to understand what goes wrong in cancer.
