What Would Your Christmas Dinner Look Like Without Bees? Most people probably say a hearty round of thank-you’s to the chef of a good dinner, and while they may have put in a lot of effort, there’s a whole bunch of silent workers out there that don’t get the recognition they deserve for helping make this meal possible: pollinators. Pollinators are important for 80% of all plant species in Europe including many fruits and vegetables. Unfortunately for us, however, many species of pollinator are now under threat and some are facing declining populations, putting our crops at risk. important beesdeclining populationsimportant bees
A Lab In South Korea Will Clone Your Dog For $100,000 People cope with the loss of their pets in very different ways; there’s no right or wrong way to deal with it. Some people are willing to go to extreme: cloning their dog. A biotech lab in South Korea offers cloning services for $100K. Its founder, Hwang, was publicly disgraced and expelled from his academic institution for fabricating research on human embryo cloning and still faces criminal charges. But this hasn’t seemed to put people; since it was established, more than 400 dogs have been cloned, and the firm usually has around 15 clients per month.400 dogs
Possible Link Between Red Meat Consumption And Increased Cancer Risk The evidence that long-term consumption of red meat is strongly linked with a modest, but significant, increase in the risk of developing bowel cancer is convincing. Scientists found that a particular sugar, which is present in high quantities in red meat, could be triggering an inflammatory immune response, which is known to encourage the development of cancers. Long-term exposure of this sugar to mice was found to significantly promote spontaneous cancers.
Why You Should Study Everything In ten years, around 65% of the jobs that people will be doing have not even been thought of yet. Existing jobs will be taken over by robotics or machines run by artificial intelligence. Almost any job that can be described as a “process” could be done by a computer housed in a robot or embedded somewhere out of sight. The Harvard professor Howard Gardner makes the case for cultivating a disciplined mind, being someone who can bring their attention to a laser-like focus and drill down to the essence of a subject, perceiving the simple truth of it. They will always find work.
Killer Cholera Bacterium Stabs Others With Tiny Spear, Steals DNA Cholera is a diarrheal disease caused by an infection of the small intestine by a bacteria. The severe dehydration it causes can kill within hours. Research shows that cholera injects toxins into surrounding cells using a tiny spear and then steals their DNA - a brilliant move that helps fuel its antibiotic resistance and virulence. Bacteria often take up DNA from other cells and incorporate it into their own genomes. The process is called horizontal gene transfer, as opposed to the conventional "vertical" transmission of genes from parent to offspring.
Opportunity Rover Has Amnesia The Opportunity rover landed on the Red Planet in January of 2004. Though it was only scheduled to have a primary mission duration of about 92 days, it is now close to reaching its 4000th day on Mars, having travelled over 25 miles. However, the crew running the mission have recently had difficulties with the rover's flash memory, essentially causing Opportunity to have a bit of memory loss when it comes to storing data long-term. The crew now plans to reformat the drive in order to restore function, a plan they are confident will allow the mission to continue.
