Naked Genetics

Could we one day be popping pills that tweak our metabolism and make us live longer? It's not as far off as you might think. Plus, the cow genome goes large, bat flu flies into focus, and an untidy gene of the month.

Every day we get older, and whether you're desperately resisting the march of time, or embracing the ageing process, most of us would agree we want to live as long, healthy lives as possible. We'll be finding out how genetics research can help. Plus, making fingers with Alan Turing, growing lizard tails, and a long-lived gene of the month.

From the beauty of a sunset or the ugliness of war to the smile on a loved one's face, our eyes bring us all kinds of information about the world around us. now researchers are working to develop new therapies for people who have lost this precious sense. Plus, smelling elephants, marmoset twins, and an all-seeing gene of the month.

Whether we like it or not, we're heading further along the road of genetic testing, not just for single genes but for complex diseases and even ancestry. But can the results of gene tests change our behaviour? Plus colouring crows, electric eels, gluing chromosomes and a sketchy gene of the month.

Twenty years ago, gene therapy was a great hope for the future of medicine - directly tinkering with faulty genes to cure diseases, but progress has been slow. Now, things seem to be changing. Plus, silencing crickets, evolving brain and brawn, and a flowery gene of the month.

The more we understand about the genetic variations that affect our brains, the more questions are raised - for example, are we a product of nature or nurture, and what should we test for? Plus, why Y loss is bad for men, the usefulness of junk DNA, and a crunchy gene of the month.

Around one in four adults in the UK experiences mental health problems in any year, and mental illness is a major problem for sufferers, their loved ones, and society. It's becoming clear that genes are involved, but what do we actually know? Plus, artificial chromosomes, autism in the womb, and a toddling little gene of the month.

Every second your DNA is under assault - not just from chemicals in our environment or food, but from the hurly-burly of life within our own cells. We'll be finding out how DNA gets damaged and repaired, and how researchers are exploiting this to find better treatments for cancer. Plus, liver from skin cells, DNA from ancient teeth, and a scary little gene of the month.

Smell is probably the oldest sense, hardwired right into our brains and closely linked to memory. Now researchers are trying to unravel the complex genetics that underpin it. Plus, contagious dog genital cancers, gene therapy for blindness, and a rather slimy gene of the month.

Hearing loss is distressing, whether it occurs later in life or in childhood. Now researchers are starting to unpick the genetic causes behind some of these problems. Plus, mice on drugs, stress and death, and a wobbly gene of the month.

Across the natural world, cells organise themselves into a wonderful array of shapes and structures. But how do they do this? Plus, building bones, plant sex in space, and a rather plump gene of the month.

All living cells are made up of protein molecules - but how do they organise themselves into structu…

The heart is a vital biological pump, beating around a billion times in a lifetime. But faulty genes…
