All week, the tech world has been piecing through rumors of a potentially catastrophic flaw in an entire generation of processors — but with all developers subject to a non-disclosure agreement, there were few hard facts to go on.
Now, new details have emerged on how severe and far reaching the vulnerability truly is. ZDNet and the New York Times are reporting that two critical vulnerabilities — dubbed “Meltdown” and “Spectre” — affect nearly every device made in the past 20 years. The vulnerabilities allow an attacker to compromise the privileged memory of a processor by exploiting the way processes run in parallel. The result, one researcher told ZDNet, is that “an attacker might be able to steal any data on the system.”
The researchers have created a website with more details on Meltdown and Spectre – https://meltdownattack.com/. Its FAQ, like many security-related FAQs, is simultaneously comforting and hair-raising. It starts with “Am I affected by the bug? Most certainly, yes.” It notes that there are patches for Meltdown for Windows, Linux, and macOS. It also notes (more…)

Recent research indicates that our increasingly Wi-Fi saturated environment could be greatly amplifying the dangers of mercury exposure from dental amalgams.

A new study published in the Journal of Neuroimmunology entitled, “Effect of radiofrequency radiation from Wi-Fi devices on mercury release from amalgam restorations,” reveals that our now ubiquitous exposure to Wi-Fi radiation may be amplifying the toxicity of dental amalgams and other forms of mercury exposure to the human body.
Brazilian researchers, in what appears to be the first study of its kind, looked specifically at the potential for Wi-Fi signals to increase the release of mercury from dental amalgams, which are composed of approximately 50% elemental mercury.

Research led by the Universities of St Andrews and Tokyo reveals a new understanding on how to create topological electronic states in solids which could fuel the development of improved materials for fast and energy-efficient electronic devices. The findings could lead to new types of computer chips that could be much more powerful than those found in today’s computers and smart phones.
The way in which electrons behave inside a solid is governed by its electronic structure, an intertwined network of ‘bands’ which define the allowed energies and momenta of electrons in the solid. If the right type of bands cross over, this can give rise to interesting, and potentially extremely useful, physical properties of materials. For example, it was recently realised that isolated touching points of these bands can be stabilised by certain crystalline symmetries, creating so-called Dirac fermions in the bulk electronic structure. This allows electrons in the bulk of the crystal to behave as though they were massless particles, effectively a bulk analogue of the atomically-thin material (more…)
Debates about internet security and the limits of state power just got a lot more interesting. Unless you don’t use the internet, you likely know that on Friday a number of major websites were down for hours. These sites were victims of a distributed denial of service (DDOS) attack targeting a DNS company called Dyn. The attack targeted not the temporarily blocked websites themselves (like Twitter and the New York Times), but rather the service (the DNS) that facilitates translations between human to computer language and allows users to connect to websites. It wasn’t that Twitter.com was down, per se, but rather that people typing twitter.com into their web browsers couldn’t find the site. The attack worked by infecting more than ten million internet connected devices like surveillance cameras with a virus called Marai—what’s known as a ‘botnet’—and using those devices to send millions of requests to Dyn’s servers, until the system overloaded and buckled.
Smartphones and tablets are replacing face-to-face interactions, and families are suffering because of it, a new study says. According to lead study author Dr. Jenny Radesky, assistant professor of developmental behavioral pediatrics at the University of Michigan Medical School, incoming communications from work, friends, and the world at large is “contaminating” family mealtime, bedtime, and playtime. Whether you agree with the term ‘contamination’ or not, I think we can all agree these times are changing due to these technological devices.
