Supramap helps track pathogens as they evolve

Collecting the genomic sequences of various strains of the influenza A virus, as well as the coronavirus that causes Severe Acute Respiratory Syndrome, has helped in the fight against outbreaks around the globe in recent years.

Using genetics, geography, and phylogenetic trees to map how different strains of pathogens evolve and mutate helps researchers predict hot spots where diseases are most likely to reemerge.

Today, the hope is that Supramap, a Web-based application that operates on parallel programming on computing systems at the Ohio Supercomputer Center and Ohio State University, will better enable researchers to map the spread of disease … Read more

Rid your computer of the Conficker virus

Let's assume you're on the receiving end of the worst April Fool's Day joke of 2009: your computer's been infected with the Conficker virus. It's a frustrating but not insurmountable problem. This guide will walk you through how to cleanse your computer and inoculate against other Conficker variants.

First off, make sure that you are actually infected. There aren't many warning signs, but a few will stand out if you know what to look for. One fast way to check is to try to visit any major security software publisher's Web site. If you've cleared your browser cache beforehand, and you can load the sites of Symantec, Eset, Avira, or AVG, you're clean because Conficker blocks access to them.

Another good litmus test is to check on the status and functionality of Windows services such as Automatic Updates, the Background Intelligent Transfer Service, Windows Defender, and Error Reporting Services. If any of those have been disabled without your consent, or if your account lockout policies have changed without approval, you might be infected. Other warning signs include unusually high traffic on your local area network, and domain controllers responding slowly to client requests.

If you're running an up-to-date virus scanner, it's unlikely you'll get infected unless you've configured your computer to not receive automatic Windows updates. Checking your list of installed updates for security update MS08-067 (KB 958644) is not recommended because the worm, alternatively known as Kido, Downup, or Downadup, fakes the patch job. … Read more

A watch for the microbiologist in your life

It's been a long while since we've posted about unreadable timepieces, and for good reason: We can't stand them. But Tokyoflash, the most shameless purveyor of these maddening devices, has truly outdone itself with the "Infection."

As best we can tell, the face of this wristwatch is supposed to symbolize a colony of bacteria or some other disgusting microorganisms, with LEDs pulsating along the way to resemble their movement. And tell time, of course, though we defy anyone to figure that out at first glance.

It's unclear what kind of statement this is meant … Read more
