Aging cells lose their grip on DNA rogues | News | R&D Magazine

Aging cells lose their grip on DNA rogues | News | R&D Magazine | Virology News | Scoop.it
Transposable elements are mobile strands of DNA that insert themselves into chromosomes with mostly harmful consequences.

Cells have evolved ways to defend themselves, but in a new study, Brown University researchers describe how cells lose this ability as they age, possibly resulting in a decline in their function and health.

Yet ANOTHER reason not to get old...B-(

Scientists take step towards drug to treat norovirus stomach bug

Scientists take step towards drug to treat norovirus stomach bug | Virology News | Scoop.it
Norovirus is the most common cause of gastroenteritis in the UK. For most people, infection causes an unpleasant but relatively short-lived case of vomiting and diarrhoea, but chronic infection can cause major health problems for people with compromised immune systems. In many cases, patients who have weaker immune systems suffer from norovirus infection for months to years, with some patients experiencing gastroenteritis for as many as eight years.
Ed Rybicki's insight:

Interesting: the same drug used to treat influenza, West Nile virus, yellow fever virus, and foot-and-mouth disease virus??

‘Let them eat cake’: A dangerous approach to bushmeat and Ebola

‘Let them eat cake’: A dangerous approach to bushmeat and Ebola | Virology News | Scoop.it
Let them eat cake—is the phrase supposedly uttered by a great princess (though often attributed to Marie Antoinette) upon learning that France’s peasants had no bread.
This is a similar response, in our estimation, to what seems to be permeating from certain quarters with respect to the consumption of bushmeat and its links to the outbreak of Ebola virus disease (formerly known as Ebola haemorrhagic fever).
A number of opinion pieces have appeared in reputable magazines such as New Scientist and
Ed Rybicki's insight:

Nice sober article about the mistake in making the kneejerk response of stopping people eating bushmeat - although if they don't, there won't be a lot left, quite soon.

Scientists unlock exact structure of Hepatitis A virus

Scientists unlock exact structure of Hepatitis A virus | Virology News | Scoop.it

Scientists have announced that for the first time, they have determined the precise atomic structure of the Hepatitis A virus. In an unprecedented step forward, a team of scientists from Beijing and Oxford have been able to map the exact construction of Hepatitis A, down to the individual atoms. 

This discovery is ground-breaking in terms of what it reveals about the history and evolution of viruses. The findings suggest that Hep A may be the evolutionary 'missing link' between picornaviruses, which infect humans and animals, and some insect viruses.

Resurrecting Smallpox? Easier Than You Think

Resurrecting Smallpox? Easier Than You Think | Virology News | Scoop.it
The virus’s genome is already online. You just need the right lab.
Ed Rybicki's insight:

Weeeeeellll...yes and no. Smallpox is a BIIIIG genome - not far off in size to the bacterial genome famously resynthesised by Craig Venter et al., a while ago.  This means it would be a huge undertaking, cost a LOT of money, and need sophisticated facilities to do it.

Not something your average cave-dwelling fanatic could do, then!

States could do it, however: a well-funded lab in even a country like North Korea could theoretically resynthesise a poxvirus - but why bother??  We have vaccines against smallpox right now; growing poxviruses and vaccinia virus in particular is a well-established biotechnology still.

SO I think this is an artificial concern, to be honest.

Vaccines are not associated with autism: Any questions??

Highlights

 

There was no relationship between vaccination and autism (OR: 0.99; 95% CI: 0.92 to 1.06).

There was no relationship between vaccination and ASD (autism spectrum disorder) (OR: 0.91; 95% CI: 0.68 to 1.20).

There was no relationship between [autism/ASD] and MMR (OR: 0.84; 95% CI: 0.70 to 1.01).

There was no relationship between [autism/ASD] and thimerosal (OR: 1.00; 95% CI: 0.77 to 1.31).

There was no relationship between [autism/ASD] and mercury (Hg) (OR: 1.00; 95% CI: 0.93 to 1.07).

Findings of this meta-analysis suggest that vaccinations are not associated with the development of autism or autism spectrum disorder.

One fifth of the world's population was attacked by this deadly virus. Within months, it had killed more people than any other illness in recorded history.
