Bioengineered tool unmasks cancer cells

Sugar-coated proteins called mucins are implicated in many diseases, including cancer. A team has now bioengineered an enzyme-based scissors that selectively cuts mucins off cancer cells, removing their ‘cloak of protection’ from the body’s immune system.

When regulatory T cells go bad

Scientists can finally hunt down a harmful kind of human T cell. Immune cells called ex-T regulatory cells (exTregs) tend to be rare in the body and, so far, impossible to detect in human samples. A new study gives scientists a reliable way to find hum…

Biologists find what colors a butterfly’s world

As butterflies flit among flowers, they don’t all view blossoms the same way. In a phenomenon called sexually dimorphic vision, females of some butterfly species perceive ultraviolet color while the males see light and dark. Biologists have discovered …
