Fish-eating spiders are crawling all over the world, scientists find.
I’ve always thought spiders made use of their web in trapping food. But apparently there’s more to spiders than just its web. 8 out of 109 spider species are able to feed on fish by injecting them with lethal doses of venom. http://www.theguardian.com/science/2014/jun/20/fish-eating-spiders-crawling-all-over-world
No-Drill Filling: Teeth To Repair Themselves.
Gladly, I’ve never had any work done on my teeth but this news will be appealing to many who’ve experienced tooth in fills. Scientists at Kings College, London have come up with a technique of repairing tooth decay using electrical pulses. https://uk.news.yahoo.com/no-drill-filling-teeth-repair-themselves-111634178.html#UAuFAZV
Mitochondrial mutation linked to congenital myasthenic syndrome
Mitochondria is a bugger. It’s an organelle found in the cells if most eukaryotic organism and it is involved in many key cellular processes such that a defect can have serious consequences.” Congenital myasthenic syndromes (CMS) are a group of inherited neuromuscular disorders characterized by muscle weakness (myasthenia)”. Scientist at New Castle University have discovered a gene defect in mitochondria which may be responsible for the abnormalities in the neuromuscular junctions of the patients. http://www.sciencedaily.com/releases/2014/06/140620120335.htm
