Fast Radio Bursts are sudden, very short but very intense blasts of radio waves that have so far defied explanation. But now the most detailed study so far has provided some clues to the origins of FRBs - they MIGHT come from starquakes. Probably not aliens. While bees are certainly the most efficient pollinators, a new study suggests that other insects - like flies, wasps, beetles and butterflies - are just as important for the success of the world's crops. It's like having a backup plan for bees. There are around 900 species of tarantula, and most of them are the usual black or brown colour. But there's more than a few of them have vibrant blue colourings - and we don't really know why. An international team of scientists has found that the development of agriculture in Europe - around 8,500 years ago - signalled the start of some significant changes in the DNA of modern humans. There were changes in height, digestion, immune system and skin colour and a host of other evolutionary steps. |

Chinese scientists have found bacteria that are resistant to one the 'last resort' antibiotics. The gene for this resistance has been found in 15 percent of meat samples and can spread to other bacteria very easily. Biologists at Tufts University have induced flatworms to grow the heads and brains of other flatworm species, without altering the worm's genome. Researchers have sequenced the genome of the tardigrade, or 'water bear'. This tiny but nearly indestructible creature has the most foreign genes of any animal studied so far - roughly one sixth of it's genome comes from other species. |

For the first time, neurosurgeons at in Canada claim to have found a way to deliver chemotherapy drugs directly to the brain, crossing the famed blood brain barrier. Women infected with hookworms seem to have decreased fertility, while women with roundworms seem to be more fertile. Because parasitic worms are weird. There's some growing evidence that suggest repeated vaccination against different flu strains might diminish the flu vaccine’s effectiveness. You should still get the shot, though. Compass is a clinical trial comparing 2.5 -yearly Pap test screening with 5- yearly Human Papillomavirus (HPV) screening. It is the first large scale clinical trial internationally to assess these screening tests in an HPV vaccinated population. |
