Scientists discover sugar molecule on HIV-infected cell plays role in evading immune system

A new study shows how key features on the surface of HIV-infected cells help the disease evade detection by the immune system. It also shows how these features can be disabled.

How alike are the cancer cells from a single patient?

Using an experimental system involving new genetic technology, researchers analyzed the gene expression signatures of a representative sample of barcoded leukemia cells. After implanting some of the leukemia cells in mice, they discovered that distinct gene expression signatures correlated with the various organs where the cancer cells ended up. They were also able to identify previously unknown genes that are involved in disease progression and chemotherapy resistance, which may offer new targets for treatment.

Students who self-identify as multilingual perform better in exams

Young people who consider themselves 'multilingual' tend to perform better across a wide range of subjects at school, regardless of whether they are actually fluent in another language, new research suggests. The study of more than 800 pupils in England found a measurable, positive relationship between their personal connection with other languages, and their GCSE exam results in both modern language and non-language subjects. This applied whether or not they actually spoke a second language fluently.

Mosaic brain evolution in guppies helps to explain vertebrate cognitive evolution

Researchers have provided the first experimental evidence that brain regions can evolve independently of each other during cognitive evolution. This so called mosaic brain evolution was verified empirically in an artificial selection experiment with guppies (Poecilia reticulata) where telencephalon size (but no other regions) differed by 10 percent after only four generations of selection. The findings can have wide implications for the understanding of cognitive evolution in other vertebrates, such as primates and humans.
