WTF?!? Arizona School Board mandates pages be ripped out of Biology textbook… but then loses big in local elections.

Gilbert, Arizona…. really? ArizonaHonorsBiology.com courtesy of MSNBC and Rachel Maddow.

After a crusading religious group showed up at the Gilbert, Arizona school board meeting with three Republican state senators to complain about the presence of a mention of abortion in an honors biology text book, the board voted to get rid of that material. It was determined that the most efficient way to remove the offending material is to literally remove it – as in, tear the whole page out of the book.

In my opinion, once you are ripping out pages of textbooks that you don’t like, it’s only a short step to burning books that you don’t like. Not to mention that censorship of academia and science has worked out real well for other groups throughout history (cough cough, sarcasm).

Glad to hear that the Gilbert School Board that mandated this blasphemous act (against science… and freedom … duh) is on its way out after losing in the elections earlier this week. For more on that, watch this video segment from the Rachel Maddow Show!

Are you a fan of science and art? ‘Dance Your PhD’ finalists announced! Watch the videos!

The annual ‘Dance Your PhD‘ contest has announced the 12 finalist videos. Definitely check them out. The winners and audience favorite will be announced on November 3rd! From John Bohannon (the founder of the contest!) in Science.

It was a tight race among this year’s 21 Ph.D. dance submissions. The previous winners of the contest scored each of them on their scientific and artistic merits, and these 12 finalists made the cut. Now it’s a dance-off between the sciences, including a tango based on robot collision avoidance, an acrobatic spectacle based on soil ecology, and, in one of the most meta Ph.D. dances ever, a hip-hop dance about the anthropology of hip-hop.

#Science Quotable: Bill Nye on the core curriculum taking down creationism

… my perception of what people don’t like about core curricula is that it forces them to learn standard stuff when they could be teaching their kids things that are inconsistent with what we know about science. I’m talking about people that want to teach creationism instead of biology. And that’s just bad. And the excuse or the justification is you don’t want the government telling you what to do. We all have to learn the alphabet everybody. I’m sorry, if we’re we’re going to have a successful society, it’s not an arbitrary arrangement of letters, you got to learn it. Sorry. And the same way if you’re asking me everybody’s got to learn a little bit of physics, chemistry, mathematics and you got to learn some evolution. You got to learn some biology. – Bill Nye for the Big Think

Vote in the Absurd Creature of the Week Competition @wiredscience

creature

 

Matt Simon at Wired.com is taking the Absurd Creature of the Week to a new competitive level by having viewers vote between different absurd creatures. Check out this weeks competition between animals for the title of ‘Most Horrifying Mouth’ and ‘Most Badass Weaponry.’

We’re coming up on one whole year of Absurd Creature of the Week! So to celebrate, we’ve used a super-secret, super-complex algorithm to choose the most absurd of the absurd—to pit them against each other in mortal combat. For the next week and a half, we’ll present you with matchups. The first round is split into categories like Battle of the Freaky Sex and Battle of the Mind-Controllers, but after that, it’s every creature for itself.

Viruses in the news: Andrew Shaw and Connor Bamford explain why for The Conversation

Why are emerging viruses here – and why now?

By Andrew Shaw, University of Glasgow and Connor Bamford, University of Glasgow

The US is on the brink of a new virus epidemic; a virus that wasn’t there ten years ago but which is now worrying officials. Chikungunya, which causes an incapacitating fever, is spread via Aedes mosquitoes and usually found across Africa and Eurasia. But it is now the most recent example of an emerging virus – viruses that are rapidly changing their geographic distribution and/or their incidence.

Other emerging viruses such as the Ebolaviruses – which go on to cause ebola haemorrhagic fever – and severe acute respiratory syndrome coronavirus (SARS-CoV), are less common while others like mumps virus, are re-emerging after a period of relative absence in the western hemisphere. These viruses arise, often unexpectedly, amid some level of mystery about where they come from and why they are spreading. Their origins are more complex than they might appear.

Arboviruses affected by climate

Viruses like chikungunya that are spread by arthropods (insects and arachnids, like ticks) are known as arboviruses (from arthropod borne)
and are affected by climate change and global warming, which directly facilitates their emergence. Global warming affects the distribution of arthropods, which act as vectors for the virus and increase the capacity for the viruses to grow within them.

An outbreak of Bluetongue virus – an infection of sheep and cattle that is spread by Culicoides midges – began in northern Europe in 2006, where it had never been seen before, and infected more animals than previously recorded.

Now, Chikungunya virus would appear set to spread across the US, much as West Nile virus did after it appeared in New York in 1999 – and which is still appearing. But not all emerging viruses are as predictable as the arboviruses.

Zoonotic viruses

A significant proportion of emerging viruses are zoonotic viruses, which spread from animals. These viruses are the most unpredictable, meaning that interaction between animals and humans is critical to their “spillover” into humans. The domestication of livestock has allowed multiple species – each with their own viruses – to come into close contact, which has created the right conditions for zoonosis.

Poultry and pigs are well known for a generation of new novel influenza viruses. However, it was also pig farms that ultimately resulted in the first cases of Nipah virus in Malaysia in 1999. Though harboured by flying foxes, the virus spread to pigs and then to humans causing around 100 deaths.

Human encroachment into new environments and the disruption of wildlife can also lead to humans being exposed to animals and their viruses. Outbreaks of ebolavirus haemorrhagic fever in African villages are often associated with the bushmeat trade.

A reproductive number

The myriad examples of virus emergence can be understood using the concept of the basic reproductive number, otherwise known as R0, which is a measure of the average number of new infections a virus produced from one single infection. An R0 of one means that an average of one new infection will arise from another, while a virus with an R0 of more than one will spread efficiently throughout a population. If a virus has an R0 of less than one it may eventually die out, as it fails to generate enough new infections over time – unless it is continuously re-introduced.

Processes that influence this number affect emergence. So while emerging viruses with an R0 of less than one may fail to efficiently infect and transmit within a new population, climate change and human behaviour could influence a virus’ R0 score in a given geographical area. Also important are virus-host interactions at the level of cells, which is a process governed by evolution. What makes viruses like chikungunya so worrying is that they require no further evolution to infect humans.

A suitable host

Viruses, as obligate, intracellular parasites that need hosts to spread, are composed of a protein or lipid coat that protects the viral genome, which encodes the instructions to make the viral proteins needed for infection. These proteins must allow entry of the virus into the host cell; make new copies of themselves; spread to more cells and evade your immune system. Differences in the efficiencies of these steps can all influence R0.

A virus’ genome can influence the fit between viral and host proteins; a virus with a better fit may be selected for and increase in frequency – which we can see as emergence.

Some viruses adapt and transmit easily, such as SARS-CoV and influenza (until we put a stop to them), while others fail to change their transmission, such as ebolavirus and the recent Middle-eastern respiratory syndrome (MERS)-CoV.

A constant worry is that an emerging virus may evolve to transmit efficiently within the human population but we do have means to prevent virus emergence. Intense monitoring of changes in virus distribution and novel human/animal infections lies at the heart of our strategy to combat emerging viruses.

For chikungunya and its relatives, targeting the mosquitoes that help it to spread and reducing the burden of climate change on at-risk areas may contain spread into new regions. The development of effective antiviral drugs and vaccines could also secure virus control. However, a challenge lies in predicting which viruses are most important and difficult in a global arena of continuing complexity and uncertainty.

The reality is that we have lived through this before with HIV/Aids and the spectre of once emerging but now-established viruses. This should continue to pique our interest in dealing with new ones that appear.
