This week on Sunday Science: the surprising shared evolutionary history of cephalopod arms and ours; a radically improved PET scanner promises revolutionary new scans; how deer antlers are providing insights into bone cancer; folic acid supplementation and a rock-eating shipworm…. Continue reading
A fairly short Sunday Science this week as I’ve been on holiday, but this week we have ways to both increase and decrease your risk of dying of a heart attack, Aztec sacrifices, 3D printing soft materials, and a genetic link to the effects of social isolation… Continue reading
In this week’s Sunday Science, tattoo art meets wearable tech, a machine that can read your thoughts, new brain cells, frogs and climate change weakening ocean currents… Continue reading
Lots of interesting stuff in this week’s Sunday Science, with syncing brains, false news, pets and depression, Jovian cyclones, predicted futures for the oceans, and more besides. Continue reading
Moving from AI back to biology, how close are we to creating life out of replacement parts? Or nothing at all? Well, we could probably clone a human being any day. This really isn’t the big deal it sounds like: there have been human clones as long as there have been humans: they’re called identical twins. In terms of the ethics, I imagine the worst is that you’d just get some unhealthily grieving people trying to clone their dead Dad, which isn’t a good idea. Clone armies to wage your wars? Well, no, it’s not going to get any faster to grow a human being and raise it to adulthood, and, for the moment, we don’t have those artificial wombs (nor are we likely to, taking an embryo from the moment of conception). You’d probably go for those AI drones instead.
Making a different form of human is another thing entirely. Continue reading
It’s the 200th anniversary of the publication of Mary Wollstonecraft Shelley’s hugely influential Frankenstein this year, which numerous news outlets are obviously picking up on. If you’ve never read it, do; it’s astounding, even today. (I’d recommend the first edition, as being more forceful than later editions). I’ll consider a few thoughts on the fears it still touches on today, then move onto the science of how we might replace human parts, or the whole, in part 2. Continue reading
Welcome to the first Sunday Science of the new year; I’m planning now to do this series fortnightly, instead of weekly, to allow me more time to write posts on more specific topics. So, due to the holiday, this week we have a bumper issue, featuring neural networks, artificial sperm, bionic hands, science fiction speculation and more.
An utterly lovely and fascinating set of interviews in Nature with some luminaries of the science fiction field, discussing “Science fiction when the future is now.” Well worth reading.
Neural networks are making it much easier to process biological images. This could be a quiet game-changer: when I was doing research not so long ago, one of the main stumbling blocks was trying to quantitatively analyse vast amounts of high quality image data. We collaborated with mathematicians, but it was a slow process to get a workable programme.
A year late, but now the data is in, it turns out 2016 was the first year in which there were less than 100,000 measles deaths a year – thanks to vaccination, which is estimated to have prevented over 20 million measles deaths between 2000-2016.
It turns out, as researchers have long suspected, that the push to produce papers for the Research Excellence Framework (REF), which determines university funding, leads to quantity over quality as it forces researchers to squeeze their work into REF cycles.
Neonicotinoid pesticides have been implicated in the decline of honeybees, but now it seems that common fungicides may also be seriously impacting bee health. (Link to original research article).
Weather fluctuations can be used to predict changes in the numbers of asylum applications (yes you read that right). On a serious note, this is more evidence for the negative effect of climate change on societal stability, and its role in promoting human conflict. Regrettably, this is behind Science’s paywall. For an earlier example of climate change driving human migration, there’s an interesting study of 19th century migration from Germany to the US here, with an accessible news feature here.
Sequencing of the sooty mangabey genome sequence (featured image) has given clues to natural AIDS resistance, as these monkeys are infected by Simian Immunodeficiency Virus (from which HIV evolved) without suffering disease. Image and more info from here.
One from the mainstream news: scientists have taken a step closer to making artificial sperm.
Finally, I’ve blogged before about the incredible advances in artificial prostheses. Now scientists have developed an artificial hand capable of providing sensation that can be used outside the laboratory (Ignore the flowery frame – the video is good).
