The Whale Menopause

Discovery ·

2016/10/03

Killer whales and humans are almost unique in the animal kingdom. The females of both species go through the menopause in their 40s or 50s, and then live for decades without producing any more offspring themselves. It is an extremely rare phenomenon. No other mammal does this, including other apes, monkeys and elephants, with the exception of another species of toothed whale. There are good grounds for thinking the menopause evolved for a reason, but why?BBC science reporter Victoria Gill takes to

Reversing Parkinson's

Discovery ·

2016/09/26

Parkinson’s Disease is one of the major neurodegenerative conditions. Cells die, for reasons not fully understood, causing a reduction in the production of the neurotransmitter, dopamine, and a raft of physical and behavioural problems. Although effective drug treatments are available, they wear off over time and have side effects. The highly individual nature of the condition and variation in its progression also makes dosage difficult. Sue Broom reports on two new approaches that could lead to
