Most cancers arise from oncogenic changes in the genomes of somatic cells, and while the cells may migrate by metastasis, they remain within that single individual. Natural transmission of cancer cells from one individual to another has been observed in two distinct cases in mammals (Tasmanian devils and dogs), but these are generally considered to be rare exceptions in nature. The discovery of transmissible...

A security research firm announced Sunday its discovery of what is believed to be the world’s first ransomware that specifically goes after OS X machines.
"This is the first one in the wild that is definitely functional, encrypts your files and seeks a ransom,” Ryan Olson, of Palo Alto Networks, told Reuters.

Autism-like behaviours and germline transmission in transgenic monkeys overexpressing MeCP2
Methyl-CpG binding protein 2 (MeCP2) has crucial roles in transcriptional regulation and microRNA processing. Mutations in the MECP2 gene are found in 90% of patients with Rett syndrome, a severe developmental disorder with autistic phenotypes. Duplications of MECP2-containing genomic segments cause the MECP2 duplication syndrome, which shares core symptoms with autism spectrum disorders. Although Mecp2-null mice recapitulate most developmental and behavioural defects seen in...
