Ancient immune defense system plays an unexpected role in cancer, MSK researchers find

Recent studies by MSK researchers show that the innate immune system helps maintain genome stability during DNA replication, and chronic activation can contribute to tumor development. The findings also suggest that problems with a protein complex called Mre11 can create an environment where cancer is more likely to occur.

A mother’s health problems pose a risk to her children

A recent study found that children born to mothers with polycystic ovary syndrome (PCOS) are at a higher risk of lower birth weight, shorter stature, and smaller head circumference. The researchers believe that the placenta's inability to meet the baby's demands due to PCOS-related hormonal imbalances may be the cause.

How hypoxia helps cancer spread

Scientists at Johns Hopkins Medicine identified 16 genes that breast cancer cells use to survive in the bloodstream, including MUC1, which is already in clinical trials. The research showed that hypoxic cells are able to migrate to higher oxygen levels and form metastasis in the body, leading to a worse prognosis.

New study challenges social media’s mental health impact

A new Curtin University study found that time spent on social media has a negligible effect on mental health indicators such as depression, anxiety, and stress. The research suggests that the relationship between social media use and mental health is complex, with some platforms having different effects on users.

Deaf male mosquitoes don’t mate

Researchers at UC Santa Barbara created deaf mosquitoes and found that males had no interest in mating, even when left with females for days. The absence of a single gene, trpVa, is responsible for this effect, which could have major implications for managing disease transmission by controlling mosquito populations.
