How new loops in DNA packaging help us make diverse antibodies

Diversity is good, especially when it comes to antibodies. It's long been known that a gene assembly process called V(D)J recombination allows our immune system to mix and match bits of genetic code, generating new antibodies ...

Study answers longstanding cell-development riddle

During the lifetime of a body—whether human, fish or any other type of vertebrate—cells die, making room for fresh new cells to carry on vital processes. The dead cells must be cleared away, though, and debris removal ...

New hair follicles can corral skin cancer

The same genetic mutations that can trigger cancer in some tissues are relatively harmless in others. A new Yale study has identified an unlikely source of protection against some forms of skin cancer—hair follicle regeneration.

Experiments illuminate key component of plants' immune systems

Plants, like humans and animals, have over millions of years evolved complex immune systems that fend off invading pathogens. But unlike many animals, plants lack adaptive immunity conferred by antibodies. This means each ...

Scientists develop novel nano-vaccine for melanoma

Researchers at Tel Aviv University have developed a novel nano-vaccine for melanoma, the most aggressive type of skin cancer. Their innovative approach has so far proven effective in preventing the development of melanoma ...

Space station cell study seeks causes of major diseases

High above the Earth, researchers are conducting a first-of-its-kind study to help patients with Parkinson's disease and multiple sclerosis on the planet below. The International Space Station experiment is looking for what ...

Listening to the whispers of individual cells

For the cells in our bodies to function as a unit, they must communicate with one another constantly. They secrete signalling molecules—ions, proteins and nucleic acids—that are picked up by adjacent cells, which in turn ...
