    Human Mini-Brains Growing Inside Rat Bodies Are Starting to Integrate

    via Inverse : Stem cell technology has advanced so much that scientists can grow miniature versions of human brains — called organoids, or mini-brains if you want to be cute about it — in the lab, but medical ethicists are concerned about recent developments in this field involving the growth of these tiny brains in other animals. Those concerns are bound to become more serious after the annual meeting of the Society for Neuroscience starting November […]

  • Can Humans Live FOREVER? Scientists Finally Have The Answer

    Can Humans Live FOREVER? Scientists Finally Have The Answer

    via Express : Scientists have continually looked at ageing as if it were a disease and have tried to cure it. From enhancing certain proteins which protect cells from ageing to extending telomeres – fragments of DNA which cap both ends of each chromosome and protect against the wear and tear of natural ageing – scientists have tried to halt the ageing process. But now, experts say they have conclusive proof there is no way […]

  • To Stay Young, Kill Zombie Cells

    To Stay Young, Kill Zombie Cells

    via Scientific American : Jan van Deursen was baffled by the decrepit-looking transgenic mice he created in 2000. Instead of developing tumours as expected, the mice experienced a stranger malady. By the time they were three months old, their fur had grown thin and their eyes were glazed with cataracts. It took him years to work out why: the mice were ageing rapidly, their bodies clogged with a strange type of cell that did not divide, […]

  • Flowers Use ‘Blue Halo’ Optical Trick To Attract Bees, Say Researchers

    Flowers Use ‘Blue Halo’ Optical Trick To Attract Bees, Say Researchers

    via The Guardian : Flowers might seem like one of life’s simple pleasures, but it turns out there might be more to them than meets the eye. Researchers have discovered that certain species of flowering plants boast tiny ridges on their petals that, thanks to variations in their height or spacing, scatter light to cast a blueish hue over the blooms. While the effect is not always visible to humans, it can be spotted by bees […]

  • Biology Week 2017: 10 Facts About Fungus

    Biology Week 2017: 10 Facts About Fungus

    via OUPblog : Organised by the Royal Society of Biology, Biology Week (7-15th October) is a nationwide celebration of the biological sciences, from microbes to photosynthesis, from yeast to zooplankton. The 8th October is UK Fungus Day, so to celebrate this, and Biology Week as a whole, we’ve put together a list of things you may not know about fabulous fungi! 1. Fungi and fungus-like organisms encompass an estimated 1.5 million species. However, fewer than 5% […]

  • Over 50% of Bacteria and Viruses Inside Human Body are Unknown to Science

    Over 50% of Bacteria and Viruses Inside Human Body are Unknown to Science

    via Sci News :  A new survey of DNA fragments circulating in human blood suggests the bacteria and viruses living within us are vastly more diverse than previously known. In fact, more than 50% of that DNA has never been seen before. “We found things that are related to things people have seen before, we found things that are divergent, and we found things that are completely novel,” said senior author Professor Stephen Quake, of […]

  • Are Stem Cells The Link Between Bacteria and Cancer?

    Are Stem Cells The Link Between Bacteria and Cancer?

    via ScienceDaily : New mechanism of stomach gland regeneration reveals impact of Helicobacter pylori infection. Gastric carcinoma is one of the most common causes of cancer-related deaths, primarily because most patients present at an advanced stage of the disease. The main cause of this cancer is the bacterium Helicobacter pylori, which chronically infects around half of all humans. However, unlike tumour viruses, bacteria do not deposit transforming genes in their host cells and how they are […]

  • Molecule in Human Saliva Has Potential for Wound Healing

    Molecule in Human Saliva Has Potential for Wound Healing

    via ScienceDaily : A study published online in The FASEB Journal delves into the mystifying fact that wounds in your mouth heal faster and more efficiently than wounds elsewhere. Until now, it was understood that saliva played a part in the wound healing process, though the extent of its role was unknown. The study examined the effects of salivary peptide histatin-1 on angiogenesis (blood vessel formation), which is critical to the efficiency of wound healing. Researchers […]

  • Hopes Rise for Anti-Cholesterol Vaccine

    Hopes Rise for Anti-Cholesterol Vaccine

    via COSMOS : An initial clinical trial testing a vaccine that may protect people against high cholesterol levels is due to finish later this year. In the meantime, the European Heart Journal features a paper by the vaccine’s inventors – a team led by Günther Staffler of Austrian pharmaceutical company AFFiRis – reporting the results of a trial using mice. The vaccine, code-named AT04A, targets an enzyme called proprotein covertase subtilisin/kexin type 9 (PCSK9). The enzyme […]

  • Five Reasons We’re Excited by How Structural Biology is Advancing Cancer Research

    Five Reasons We’re Excited by How Structural Biology is Advancing Cancer Research

    via ICR : Several research teams at the ICR are devoted to structural biology – a crucial discipline in cancer research that is shedding light on some of life’s most fundamental processes. We are excited about the potential this field has to enable the discovery of brand new cancer drugs. There are five key reasons why structural biology research excites us: It means we can look at proteins in atomic detail We can use X-ray crystallography […]
