Hyper-Threading Considered Harmful

Hyper-Threading, as currently implemented on Intel Pentium Extreme
Edition, Pentium 4, Mobile Pentium 4, and Xeon processors, suffers from
a serious security flaw. This flaw permits local information
disclosure, including allowing an unprivileged user to steal an RSA
private key being used on the same machine. Administrators of
multi-user systems are strongly advised to take action to disable
Hyper-Threading immediately; single-user systems are not affected.more

Serious Crypto problem with VPN Tunnels

Britain’s national emergency response team, the National Infrastructure
Security Coordination Centre, issued a warning this week about the
safety of virtual private networks that use IPsec encryption and
tunneling to connect remote workers to corporate networks. The flaw,
which the NISCC rates as "high" risk, makes it possible for an attacker
to intercept IP packets traveling between two IPsec devices. more

Nuclear battery with 10 year life

A battery with a lifespan measured in decades is in development at the
University of Rochester, as scientists demonstrate a new fabrication
method that in its roughest form is already 10 times more efficient
than current nuclear batteries—and has the potential to be nearly 200
times more efficient. The details of the technology, already licensed
to BetaBatt Inc., appears in today’s issue of Advanced Materials. more

Wire in the Blood!

A Japanese research team has developed a fuel cell that runs on blood
without using toxic substances, opening the way for use in artificial
hearts and other organs. The biological fuel cell uses glucose, a sugar
in blood, with a non-toxic substance used to draw electrons from
glucose.“Since the electron mediator is based on Vitamin K3, which exists in
human bodies, it excels in safety and could in the future generate
power from blood as an implant-type fuel cell,” the group said in a

Most other bio-fuel cells under study use a metal complex, spawning concern about harm if used for implants.

The newly developed cell in the size of a tiny coin is able to
generate 0,2 milliwatts of electricity, enough to power a device that
measures blood sugar level and transmits data elsewhere, the group said.
