One specific protein may be a master regulator for changing how cancer cells consume nutrients from their environments, preventing cell death and increasing the likelihood the cancer could spread, a study has shown.
Protein rewires metabolism to block cancer cell death, may allow cancer spread

Researchers have developed a new way of using nanomaterials to identify and enrich skeletal stem cells -- a discovery which could eventually lead to new treatments for major bone fractures and the repair of lost or damaged bone.

Research shows that periodontitis, severe gum disease, is linked to higher blood pressure in otherwise healthy individuals. This study of 500 adults with and without gum disease found that approximately 50% of adults could have undetected hypertension. Promotion of good oral health could help reduce gum disease and the risk of high blood pressure and its complications.
People with severe gum disease may be twice as likely to have increased blood pressure

Sustained low-intensity exercise does not completely counteract the effects of weightlessness on the heart muscle, which will atrophy over time in a gravity-free environment. Short bursts of repeated high-intensity activity during shorter space missions may be more successful in keeping the heart healthy.
Long-term space travelers will need high-intensity exercise to protect heart health

Bullying at boarding schools has a negative impact on students' emotional health, but for male students, having a school staff member to rely on for support may mute the harmful effects of bullying, according to a new study. Support networks did not have the same effect for female students, the researchers say.
Mental health support at schools helps male, but not female, students feel safe from bullying

Scientists have genetically engineered immune cells, called myeloid cells, to precisely deliver an anticancer signal to organs where cancer may spread. In a study of mice, treatment with the engineered cells shrank tumors and prevented the cancer from spreading to other parts of the body. The study, led by scientists at the National Cancer Institute’s (NCI) Center for Cancer Research, part of the National Institutes of Health, was published March 24, 2021, in Cell.
Engineered immune cells deliver anticancer signal, prevent cancer from spreading
