Has a picture with some BBC computers working at ITN on security when the internet was first developed in 1974. On feed from Reuters and other agencies. He would type election results in to news graphics generator. Account hijacking such as taking someone's Facebook account is typical attack related to clicking on dodgy link or visit dodgy page. Buffer overflow 40 year old known vulnerability that was exploited recently. Heartbleed vulnerability. Delay in applying patching software led to the vulnerability being so widely exploited. One point of concern is sticking someone else's USB stick, a known way malware can be introduced. Companies can be fined ...

Illustration of negative refraction taken from On The Properties of Optical Metamaterials Report Author: W.O.L. Bellamy, M.T.A. Hatcher et al. Optical metamaterials are an artificial type of composite material, with the unique property of refracting light ‘negatively’, or in the opposite way to conventional materials using the conventional optical model. Due to this they are also known as Negative Index Materials (NIMs) or Left-Handed Materials (LHMs). The field of optical metamaterials was originally conceived by Soviet scientist Victor Veselago in 1967 with the theoretical possibility of negative refraction using a combination of both simultaneously negative permeability and permittivity values. It was not until Sir John Pendry’s further theoretical work on this concept enabled the first physical demonstration of negative refraction by Dr D.R. Smith in 2001. Pendry showed that it was possible to create an effective negative permittivity and permeability on a scale larger th...
