There's no limit to viral ruthlessness. These lifeless packets of genetic code cause countless ails, often without a known cure. One such monster spends most of its time as a seemingly benign strand of DNA that could sit latent for years before striking, causing cells to turn into a rare but aggressive form of skin cancer called Merkel cell carcinoma.

Millions of years ago, our ancestors' bodies may have waged an epic battle against a virus. Through a sneaky DNA swap, the hosts would have gotten the upper hand, and turned the virus' defences against themselves. Researchers think they have unearthed the whole ordeal, left like a Dead Sea scroll in our genes.
Experts say it's not a matter of if, but when a global scale pandemic will wipe out millions of people. And we are grossly unprepared for the next major outbreak. But in the event of a devastating pandemic — whether it be triggered by a mutated strain of an existing virus or a bioengineered terror weapon — there are some practical things you can do, both before and during the outbreak, to increase your odds of survival.
It's a scary fact of digital life that there are a lot of ways your PC can be exposed. Maybe you've been hacked by a state agent, or cracked by weird Nazi trolls. Fortunately you're not powerless, and there are lots of ways to fight back. You don't need to be a hacker, cracker, or computer savant to protect your laptop.
Earlier today, the World Health Organisation declared that the Zika virus, along with its related neurological complications, no longer constitutes an international emergency. The announcement is a troubling development that could threaten important research, while also undermining those who are most affected, namely women, children and the poor.
Scientists have learned that upwards of 25 per cent of all people who become infected with Ebola show none of the typical symptoms. The finding suggests the recent West African Ebola Epidemic was more widespread than previously thought, and that new methods need to be developed to diagnose and contain the dreaded virus during an outbreak.
British red squirrels are being afflicted by a medieval strain of leprosy that was thought to have disappeared from Europe over 700 years ago, according to a new DNA analysis. Researchers say the chances of the dreaded disease spreading to humans is low, but the discovery suggests this strain of leprosy has been lingering for quite some time.
Yesterday, Florida Governor Rick Scott announced that 10 more people in Florida have contracted the Zika virus, likely through mosquito bites, bringing the total number of confirmed cases to 14 cases. Citing the increase, the governor also asked the Centres for Disease Control and Prevention to mobilise an Emergency Response Team to help the state with its "investigation, sample collection and mosquito control efforts".
A new study published in the New England Journal of Medicine suggests that Zika-infected women who are in their third trimester have virtually no chance of having children with microcephaly. Troublingly, the same study shows that women who exhibit no symptoms can still give birth to babies with brain abnormalities.
In preparation for the upcoming Olympics in Brazil, a British long jump champion is planning to freeze his sperm just in case he contracts Zika. It's meant as a precaution to prevent any future children from developing birth defects, but in reality it's a complete overreaction based on unfounded fears.
While the West African Ebola Outbreak largely came to an end back in January, isolated cases are still appearing, including two cases which emerged this week in Guinea.
Mimiviruses are viruses so big they can actually be seen with a simple light microscope. European scientists have now learned that these bizarre organisms have their own immune system that makes them virtually invulnerable to predatory viruses, suggesting these creatures may actually represent a new branch in the tree of life.
