Actively Beneficial?

How should we describe a lifestyle change that doubles our likelihood of suffering a major traffic accident? Oddly,  evidence from Scotland suggests the answer is "worth making". Let me explain.

Unpoking the bear

The human immune system is a powerful defender, using its arsenal of antibodies to identify and attack foreign pathogens. But such antibodies have a potential dark side: autoantibodies that begin to attack, not invading microbes, but healthy tissues.

Turning Back The Clock

We previously discussed the concept of biological and epigenetic measures of aging. One use for such epigenetic clocks would be in determining the extent to which any regenerative medical intervention is actually working.

Reheating a Cold Case

In criminal investigation, it is well known that passing time obscures the facts, making what happened more difficult to discern. Eventually, the case turns cold - unlikely to be solved unless we discover new evidence. In some ways for over a century, epidemiologists have been dealing with just such a cold case, picking through the rubble of the 1918 Influenza pandemic and trying to make sense of what they find. But as we will see, debate continues in a number of areas.

No Thanks for the Memory

That there is "no substitute for experience" is a truism, and one that is very tempting to apply wholesale to human immunity. Indeed, we previously touched upon an particular feature of the 1918 Spanish Flu outbreak, the so-called "W-shaped" mortality impact resulting in disproportionate fatalities amongst younger adults in the 20-40 range.

EDS - Enhanced Dedicated Servers

A large part of our service has traditionally revolved around Dedicated Servers — parallelised instances of our applications running on multi-threaded platforms for a single license holder (in contrast our shared servers offer single-thread performance in a multi-tenant way to multiple license holders, a model that is suitable for only the least demanding use-cases).

A Problem of Excess

Epidemics and pandemics are, by definition, fast-moving and difficult to track. These are the diseases that we couldn't keep a lid on, outbreaks that breached our initial efforts at control. It follows then, that ongoing reporting of such diseases won't be entirely accurate, subject to various limitations imposed by testing and recording protocols. This reality is misused by some who believe that reported impacts are exaggerated and societal responses unjustified, but such a belief runs counter to the evidence.
