New immunotherapy shows promising results against bone cancer

Bone cancer is the leading cause of cancer-related death because it is resistant to chemotherapy.

Now, University College of London researchers say they have developed a new immunotherapy that shows promising results against osteosarcoma, a bone cancer.

They say they can offer an efficient and cost-effective bone cancer solution by using a small subset of immune cells.

Developers say these cells, derived from healthy donor immune cells are safe without the risk of graft versus host disease.

Research shows periods are starting earlier

Girls are getting their first menstrual period earlier.

Harvard doctors studied more than 71,000 girls to find the average age of periods getting younger while the age when menstrual cycles become regular is getting older.

The trends were strongest among racial minorities and those of low socioeconomic status.

Researchers also suggest weight may play a role.

Excess weight impacts hormones and can have implications for a lifetime.

Dietary patterns, psychological stress, adverse childhood experiences, pollution and endocrine disrupting chemicals also play a role.

The earliest age of first menstruation was eight.

Patterns show evidence of baby language

Babies can talk long before we know it.

A new analysis of those squeals and growls reveals significant cluster patterns.

A team of researchers from the University of Alabama and the University of Texas coded infant vocalizations, revealing early language.

The most prominent sounds are vowel-like utterings.

Study authors recorded baby sounds for 130 infants every day for the first year of life.

The babies spontaneously produced sounds and uttered speech-like vocalizations.
