Lab notes: what a mammoth week for science!
Yes it ’s a big story in more ways than one – a team of Harvard scientists say that scientists say they are on thebrink of being able to create a hybrid elephant-mammoth embryo. There are lots of technical and ethical concerns to address before we actually have real, live mammoths (or mammophants, as they ’re being called by some) but the idea of “de-extinctifying” something that’s been gone for 4,000 years is pretty exciting. This isn’t the only genetic engineering story in town this week, though, as amajor US report out this week has prepared ground for genetic modification of human embryos, eggs and sperm ...

The robot suit providing hope of a walking cure
Clothing that can help people learn how to walk again after a stroke is the brainchild of a Harvard team reinventing the way we use robot technologyConor Walsh ’s laboratory at Harvard University is not your everyday research centre. There are no bench-top centrifuges, no fume cupboards for removing noxious gases, no beakers or crucibles, no racks of test tubes and only a handful laptop computers. Instead, the place is dominated by clothing.On one side of the lab stands a group of mannequins dressed in T-shirts and black running trousers. Behind them, there are racks of sweatshirts and running shoes. On another wall of s...

Neurons in the brain switch identity and re-route fibres | Mo Costandi
New findings could one day lead to gene therapies for stroke and spinal cord injuriesThese drawings by Santiago Ramón y Cajal show the cellular structure of three different areas of the human cerebral cortex. The cortex is the seat of higher mental functions such as language and decision-making, and contains dozens of distinct, specialised areas. As Cajal's drawings show, it has a characteristic layered structure, which differs somewhat from one area to the next, so that the layers vary in thickness according to the number of cells they contain. Cells throughout the cortex are arranged in a highly ordered manner. Those in...

Humble Aspirin could cut risk of heart attack - from Guardian archive, 28 Jan 1988
Twenty-five years ago, a study claimed that heart problems could be avoided by taking tablets designed for mild pain reliefMen with outwardly healthy hearts can cut the future risk of heart attacks by 47 per cent if they take an aspirin every two days, a United States study claims today.Advance word of its publication in the New England Journal of Medicine brought warnings from specialists about the danger to stomach linings of a rush to the aspirin bottle by either sex.Work in Europe and the US over the past two years has commended aspirin as an anti-blood clotting agent for heart and stroke sufferers. Advice on dosage we...

Lucy Mangan: wanted – mother for Neanderthal baby
'Don't you long, occasionally, for something really, really interesting, something different, something overwhelmingly "other" to happen?'It's possible that the snow has driven me stir crazy. Although, as someone who, when under stress, still draws diagrams of the underground, Womble burrow-based home that she plans to build when she wins the lottery, I think that is highly unlikely. In any case, I have been seized by the idea of having another baby.Not just any old baby – I've already got one of those – but a Neanderthal baby. Earlier this week Professor George Church, a genetic researcher at Harva...
