Preliminary study in lab-grown cells raises possibility of cancer diagnosis without biopsies. Imaging tests like mammograms or CT scans can detect tumors, but figuring out whether a growth is or isn’t cancer usually requires a biopsy to study cells directly. Now results of a Johns Hopkins study suggest that MRI could one day make biopsies more effective or even replace them altogether by noninvasively detecting telltale sugar molecules...

Scientists say our brains may not be as complicated as we once thought – and they’re using sea slugs to prove it. Led by graduate student Angela Bruno, researchers at The University of Manchester and Rosalind Franklin University of Medicine and Science in Chicago mapped how neurons fired in the brain of the large sea slug Aplysia while it moved. “What happens in the brain during movement is currently only well understood for...

Young adolescents are more swayed by the opinions of their peers on how risky a situation is while adults, older adolescents and younger children are more influenced by the views of other adults. These are the findings of a new study from a research team in University College London, published in the journal Psychological Science.

Say you’re out shopping for basic household goods — perhaps orange juice and soup. Or light bulbs. Or diapers for your young child. How do you choose the products you buy? Is it a complicated decision, or a simple one?

Colonisation of the upper airways with a harmless bacteria called Neisseria lactamica reduces both pre-existing and newly acquired infection with meningococcal disease-causing Neisseria meningitides. This is the major finding of a new study on university students, a group at high risk of this often serious illness, published today in the journal Clinical Infectious Diseases. The study comes from a team of researchers based at different...
