Mapping out the Milky Way

Mapping out the Milky Way

This autumn, the Gaia spacecraft will be launched on a mission to find out where the Milky Way’s stars came from. I catch up with two of the astronomers at the Lund Observatory who’ve worked on designing the spacecraft, and with one of the astronomers who’s hoping to use data from the spacecraft to calculate where and when the stars of our galaxy formed.
Plus, I hear about a new technique which is being used to work out what the atmospheres of planets around other stars are made of, and about observations of a recent gamma ray burst which are helping us to unravel what triggers these strange cosmic phenomena.

Genes, infections and immunity

Sneeze (c) CDC

Why can some people stay fit as a fiddle, while other seem to catch every bug that’s going? As you might expect, the answer lies in our genes. Plus, a multitude of mutant mice, the state of gene therapy for epilepsy, and an unseeing gene of the month.

    00:57 – Dr Julian Knight – Genes and immunity

    Why do some people fight off infections easily while others become seriously ill? The answer is in our genes, as Dr Julian Knight explains.

  • mouse (c) Rasbak

    08:56 – Many new mouse mutations

    Researchers have published the first results from an ambitious study to knock out, or delete, every gene in mice.

  • Lung Cancer (c) Emmanuelm

    13:03 – Tracing lung cancer

    Cancer Research UK scientists have announced an ambitious project to track the evolution of lung cancer in more than 800 patients.

  • Obese Mouse (c)

    16:24 – Is fatness in the genes?

    Scientists have discovered that mice carrying a faulty version of a gene called Mrap2 gain weight, while eating the same as normal mice

  • Cholera Bacteria (c) Ronald Taylor, Tom Kirn, Louisa Howard

    17:09 – Genes and cholera

    Researchers studying people in Bangladesh have tracked down genetic regions that affect susceptibility to cholera infection.
