In this week’s Sunday Science: some facts on the new coronavirus that is spreading through China (and abroad); how stress turns your hair grey; how scientists are stressed (so we’ll all go grey early); how human body temperatures are falling, and growing your own snake venom…. Continue reading
Welcome to the first Sunday Science of the New Year, with carnivorous plants, injecting new life into an old vaccine, reducing schizophrenia risks (by dogs), how the UK transformed its energy supply, and how flies land upside down on your kitchen ceiling… Continue reading
In this week’s Sunday Science some nice medical advances: a promising new HIV vaccine trial, approval of a drug for ovarian cancer and a potential game-changer with gene edited blood cells to treat blood disorders that affect millions of people. Also: spooky green fluorescent sharks, our twisted galaxy, green energy, and embryo development. Continue reading
This week’s Sunday Science covers what makes our brains different from monkeys, but occasionally like Neanderthals, a highbrow way to beat depression in old age, new drugs in the fight against malaria, a giant subterranean ecosystem, and the first sounds from Mars… Continue reading
Sunday Science had a brief hiatus last week, due to workload and family commitments, but we’re back this week instead, with gene edited humans, how your birth affected your brain, how MRSA can evade the immune system, brainwaves in a dish, and spiders that nurse their young… Continue reading
Welcome to this week’s Sunday Science, featuring the driving forces behind human brain evolution, a gel to help the brain heal after stroke, organoids, carbon nanotubes, gluten sensitivity and an archive of the pick of 2017’s groundbreaking research articles… Continue reading
Welcome to this week’s Sunday Science, with self-reproducing crayfish, breakthroughs in developmental biology, the quantum internet, and cleaning.
A big story that’s just hit the mainstream news: scientists have managed to grow sheep embryos containing human cells: 1/10,000 of the sheep embryo’s cells were human, after 28 days of development. This offers the potential of radically improving transplants, and builds on the group’s previous success with pig embryos, but with tenfold efficiency.
An invasive crayfish spreading through Madagascar is a recent hybrid species that reproduces through parthenogenesis – as in, without mating, with the unfertilised egg developing into an adult by itself.
Researchers have found a way to artificially treat wood,compressing it in a way that substantially increases its strength and stiffness and offers more engineering possibilities for this sustainable (when managed) material.
The axolotl genome has been sequenced (open access: technical). The Mexican salamander, as it is also known, is an important model in developmental biology, with scientists keen to understand how it can regenerate it’s limbs. Already the genome has thrown up a lot of information and a few surprises: it lacks a key gene, Pax3, that is essential in other vertebrates.
Still on the subject of developmental biology: scientists are attempting to create a “human developmental cell atlas” – mapping the development of humans from embryos at a single cell level (open access, bit technical). This is in conjunction with the Human Cell Atlas, here, and made possible by modern molecular methods that allow us to minutely examine which genes are active in which cells.
A nice piece on the future of the (potential) quantum internet, long theorised by both science fiction authors and scientists.
And finally: women who do lots of cleaning at home have a greater risk of decline in lung function. Men don’t, apparently, so clearly they should be doing all the cleaning!
