How early-stage cancer cells hide from the immune system
A new study finds precancerous colon cells turn on a gene called SOX17, which helps them evade detection and develop into more advanced tumors.

How Cognition Changes Before Dementia Hits
Study finds language-processing difficulties are an indicator — in addition to memory loss — of amnestic mild cognitive impairment.
Hitchhiking Cancer Vaccine Makes Progress in the Clinic
Therapeutic cancer vaccines are an appealing strategy for treating malignancies. In theory, when a patient is injected with peptide antigens — protein fragments from mutant proteins only expressed by tumor cells — T cells learn to recognize and attack cancer cells expressing the corresponding protein. By teaching the patient’s own immune
Polyglots, There’s Something Special About Your Native Tongue
A new study of people who speak many languages has found that there is something special about how the brain processes their native language.
In the brains of these polyglots — people who speak five or more languages — the same language regions light up when they listen to any of the
Exposure to Different Kinds of Music Influences How the Brain Interprets Rhythm
When listening to music, the human brain appears to be biased toward hearing and producing rhythms composed of simple integer ratios — for example, a series of four beats separated by equal time intervals (forming a 1:1:1 ratio).
However, the favored ratios can vary greatly between different societies, according
Exploring the cellular neighborhood
Cells rely on complex molecular machines composed of protein assemblies to perform essential functions such as energy production, gene expression, and protein synthesis. To better understand how these machines work, scientists capture snapshots of them by isolating proteins from cells and using various methods to determine their structures. However, isolating
Graphene Unveils a Quantum Quirk: Electrons Fractionalize Without a Magnetic Field
MIT physicists have now observed fractional charge effect in a surprisingly simple setup: five layers of graphene, a material derived from graphite.
