What to watch: Between, S1 E2

Another one of the Canadian/Netflix on demand series, Between season 2 became available in June. A virus kills all inhabitants aged over 21 in  a US town called Pretty Lake. The town is quarantined and the children and young adults are left to fend for themselves,  leading to a YA “Lord of the Flies”. Of course, there’s a government conspiracy, which creates an unlikely situation of supply airdrops absence.  But despite a few plot holes, The characters are compelling, the plot moves along nicely.

Unfortunately, unlike in my favorite human cloning series, Orphan Black, the science of Between is completely bogus. A scientist who sneaked into Pretty Lake with  an experimental vaccine looks at something round and red swirling on the screen (red blood cells?) and the vaccine represented by a yellow  shimmering circle around them. He says that the virus sits inside cells and eats them  from inside out, which is represented by churning and undulating cells as if an alien is trying to get out. The cells resist the virus until the 21st birthday date when boom! cells collapse and the person dies.

21 is the age of adulthood in the US when you suddenly allowed to drink, while you could marry, drive a car and join the Army before that magical date. From the biology point of view, 21th birthday is a completely arbitrary date. A  virus wouldn’t know when precisely you were born – it’s virus, not a notary. In the absence of a document, it’s difficult to even estimate a persosn’s age – people who don’t have their birth certificate pass as underage for years and a convincing fake ID would age you.

Yes, there are viruses, which cause diseases in  (mostly) children, for example, notorious mumps, measles, and rubella viruses. This apparent age specificity is caused by  children’s underdeveloped immune systems as it’s still possible to get infected as an adult if you miss the childhood infection or not vaccinated. Assuming, that it’s possible to create a virus, which targets adults, it should hit anybody who reached an age of puberty, which can vary between 10 and 20 depending on the environmental conditions.

It’s the general condition of your body that would matter to a virus, not your birthdate. We all heard about a sprightly 90 yeas old, who run marathons and know 30 y.o. who look and have the health conditions of people of twice their age.

 

Elementary, S1E24, “Heroine”

The first season ends on a sentimental note. Sherlock invites Watson on the roof where he keeps his hives. He tells her that he had managed crossing the rare solitary bee he obtained as a payment in one of the cases (S1E17, “Possibility Two” ?) to the honey bee. The hybrid is a new species, which he is going to name after Watson – E. watsonii.

I get the metaphor: Sherlock = solitary bee, honey bee = humanity and Watson had helped Holmes to return from his heroin addiction. But the highly unlikely hybrid of two separate  genuses (a taxon higher than species) is not a new species . “E. watsonii” can be sterile, e.g. unable to reproduce as a cross-genuses horse x donkey hybrid – mule. And even if it is fertile, a species should be stable during tens of years and in a natural habitat.

So sorry, Watson, I don’t think you’ll have a species named after you.

Elementary, S1E21, “A Landmark Story”

The villain of the day said:

…I constructed an antibiotic resistant rubella strain in the lab.

Rubella of “mumps, measles and rubella vaccine” fame is a virus.

Antibiotics do not work on viruses, so it is impossible – and useless – to engineer a resistant strain.

Wikipedia’s plot summary:

 Holmes investigates when a wealthy philanthropist believes he was intentionally infected with an incurable illness — cerebral amyloid angiopathy (CAA); Holmes sends Joan to a suspicious dry cleaners to teach her deductive skills.

CAA  is the result of an insoluble protein accumulating in the  brain cells. In the episode  this is caused by a drug-like molecule, which “specifically targets the gene”, which is impossible. If they’d only changed “gene” to the protein itself, it would have been much  more believable.

Secondly, the detective receives the drug formula as a picture to his mobile and spends a night “solving the formula, determining where carbon, oxygen and nitrogen atoms go “. The formula on the screen briefly, and looks complete – anybody with a bit of chemistry training,  for example his sidekick Joan Watson, would have told him the formula.

What I did like was the idea that blood test can be faked by mixing a “DNA-less” blood-like substance (for example, artificial plasma and anybody’s red blood cells – they don’t contain nucleus = DNA) with DNA synthesised to match a suspect 11 genetic markers (bits of his DNA). As nobody determines sequence of the whole length DNA, relying on the markers match, I cannot find a fault with the idea.

Independent scientist?

British Channel 4 has  a five minutes program “4thought TV”, which consists of a monologue about a point of contention, for example whether “atheist churches” are a good thing. One of the speakers discussing whether it is ethical to eat meat was a 70-ish man described as “an independent scientist”. He was talking the usual nonsense about artificial meat grown in vitro – believable in sci-fi novels by Bujold but not in reality to anybody who knows the expense of animal cell culture. But I was more intrigued by his title, “an independent scientist”. Is there such a thing as a scientist without affiliation to a scientific institution?

Can I work as a cleaner and be an independent scientist in my heart and mind?
