stop the killing

Open Archive Day


We are already causing a mass extinction by taking up more space than any other species, but some peopl aren't content with that and feel the primeval urge to go out and kill some animals to speed the extinctiona along. I have had a couple of features on how humans are messing up biodiversity by killing the wrong kinds of animals (eg top predators like sharks and tunas) and how the industrialisation of the oceans is threatening the megafauna that survives there.

Last year's hunting feature was mainly an appeal to stop the killing, and to that purpose I rounded up examples of species threatened by hunting on land, in water and in the air. The feature is now in the open archives:

according to Bach

In the fourth month of the Plague Year Bach Project I managed to memorise the Sarabande from the first suite. At 16 bars total length, this movement is reasonably gentle on the poor old brain cells, but I had to get my head around the chords, which are plentiful and essential. Turns out they are all fairly normal, inoffensive chords, such as G major, C major, A minor, D major. Nothing I can't handle. I'm not entirely sure I understand the concept of a sarabande though - to me it feels like a glacier sliding down a mountain slope, so I don't quite feel the beat or imagine people dancing to it.

So onwards to the Courante (1.3), which has a scary number of notes at a scary speed, but also a bit more of a catchy tune. Wish me luck.

Resources for this movement:

A slow version from Cellopedia is a helpful starting point as the fingerings are clearly visible at all times. And he plays at a speed that even I can manage (at the end of July, once I've learned the notes).

For a more engaging performance at the proper speed, try this recording from Denise Djokic.

And then consider the helpful hints from Inbal Segev. She's done a short tutorial (or two in some cases) for every single movement.

I'm also adding these videos to my youtube playlist "cello repertoire".

Life in the galaxy: maybe this is as good as it gets?
Researchers have found that rocky exoplanets which formed early in the life of the galaxy seem to have had a greater chance of developing a magnetic field and plate tectonics than planets which formed later. As both these conditions are considered favourable to the development of life, this means that if life exists in the Galaxy, it may have developed earlier than later, and that planets formed more recently may have less chance of developing life.

forests feel the heat

Around the world, people are planting trees and fighting to stop deforestation in the hope that the carbon capturing magic of forests might save us from the worst of the climate disaster we're causing. But what if the forests themselves can't stand the heat? In my latest forest-y feature I looked at a new paper that found some resilience but also a new tipping point for tropical forests, and also at forests that are already dying from causes related to climate change, eg in Germany.

The current technique used for counting lion populations for research and conservation efforts doesn't add up, according to a University of Queensland researcher.

"African lions receive immense publicity and conservation attention," Mr Braczkowski said."Yet their populations are thought to have experienced a 50 per cent decline since 1994 - coincidentally the same year Disney's The Lion King was released."

roots of religion

Open Archive Day

Last June's special issue of Current Biology was about cooperation and conflict - always a lot of that going on on this planet! - and my contribution was about the origins of religion, seeing that it has been the cause of both cooperation and conflict. Although right now, with so many other things to worry about, we hardly remember religious conflicts.

Anyways, my feature, along with the rest of this very interesting special issue is now in the open archives, which means free access for everybody, forever. Enjoy!

oxford's black history

Today there is a STEM / academia strike going on in support of Black Lives Matter, and even Nature is supporting it. So I'm not doing any science news today. Instead I'll use this entry to collect some local (and possibly wider academic) issues relating to the matter. Let's see what I can find.


gown

Rhodes Must Fall - the statue at Oriel College has been the focus of attention after the toppling of Colston at Bristol, but there is Rhodes House, the Rhodes scholarships and all that. (Although personally, I am more offended by the building hidden behind Rhodes House, the Vere Harmsworth Library of the Rothermere American Institute. Both were named after an actual fascist and his lovely family clan, and not in a distant past, but in this century.) Here is a comment from an Oriel alumnus.

The Codrington Library at All Souls. Endowed by Christopher Codrington (1668–1710) with the spoils of slave work on sugar plantations in the West Indies. Then again, it's a library accessible to all members of the university, so we don't really want to burn it down. Maybe a shift of collection emphasis could do the trick?

A 2015 campaign to decolonise Oxford's curriculum. Which is where I found out about Codrington. Bit disappointing though, surely there must be many more skeletons in Oxford's closets?


town

The Black Boy in Headington - I discovered this pub and hotel when I was looking for a new pub to hold Galician sessions near the London coach stops, so I specifically looked around Headington. While the Black Boy looks nice from the outside and has a great location, the name put me off so much that I didn't even look inside. This local history page tells me that the niche above the entrance had a sculpture of a black servant until it was destroyed in 1990. Then there was painting of a chimney-sweep to replace it, now the niche is empty and there is an image of a black horse above, in an attempt to pretend the name doesn't mean what everybody understands it to mean. The name is old (documented in 1805) but not the first name this pub had, and the current building only dates from 1937, so history isn't much of an argument for keeping the name.

Update: Oxford Mail reports the owners of the pub will not change the name.


further afield

I hear the De la Beche Society at Imperial College is going to get a new name, considering that the patron, geologist Henry de la Beche (1796-1855) owned slaves in Jamaica. However, I am also told that he "inherited slaves and wealth from plantations yes, but abolished corporal punishment, gave them better working conditions, was criticised by other slave owners, and was not opposed to abolition." I gave a talk at the De la Beche society many years ago (on Life on the Edge), and have to admit that I only remember the name because I was amused by the literal meaning "of the shovel" which was very fitting for a famous geologist.

And Tower Hamlets council have removed the statue of slave trader Robert Milligan that previously stood at West India Quay yesterday, sending Tory imperialists into convulsions ...

astrobiology

New research shows how complex chemistry may be relevant to origins of life on Earth
Scientists would like to understand how life began on Earth. One popular model suggests life began when simple RNA molecules capable of copying themselves formed spontaneously in primitive environment. How this happened remains a vexing problem. New research by scientists from Earth-Life Science Institute (ELSI) at Tokyo Institute of Technology and the University of New South Wales suggests that simple organic compounds exposed to high energy radiation may be predisposed to form molecules like RNA.

Why the Victoria Plate in Africa rotates
The East African Rift System is a newly forming plate tectonic boundary at which the African continent is being separated into several plates. According to GPS data, one of those, the Victoria microplate, is moving in a counterclockwise rotation relative to Africa in contrast to the other plates involved. Now, researchers have found evidence that suggests that the configuration of weaker and stronger lithospheric regions controls the rotation of continental microplates and Victoria in particular.

living on leaves

It is now widely known and appreciated that the bacteria in our guts are making an important contribution to our metabolism and wellbeing. Similarly, we are aware that the space around plant roots, the rhizosphere, is hosting a whole network of organisms interacting with the plant and with each other.

What is relatively new, however, and was completely new to me, is that plants also have a microbiome above ground, and that this may be as crucial to their health as the one below ground. This isn't quite as comprehensively understood yet, but a few studies have emerged recently, which I have had a look at for my latest feature, which is out now:

the first 40,000

So the official deaths from Covid-19 in the UK passed 40,000 with those announced yesterday (the real death toll is more likely to be above 60,000, but let's stick with the official figures for now). As the mishandling of the crisis continues at full speed, I fear there will be many more to come.

According to yesterday's govt. briefing, there are now only 5,600 new infections per day - I don't believe a word of this. I follow the daily deaths announced and calculate the rolling 7-day average, which I think is the only halfway reliable figure. (Previous results and predictions here.) Unfortunately, this figure has remained roughly constant for the last ten days, probably as the result of the May 11 switch from "stay home" to "stay alert" messaging. It was 236 yesterday and 244 on May 26. (Update: Today, Saturday the figure stands at 235, the 13th day without significant decrease.) On June 2 and 3 it even appeared to be rising (by 10% and 5%, respectively) compared to the value a week earlier.

So when the govt. ministers and "scientists" are saying "it's not going down as fast as we would wish" this is misleading. In truth, it's not going down at all. And on the assumption that we are stuck on well above 200 daily deaths, that means that there must have been more than 20,000 new infections per day in recent weeks. Telling the public that we have 5,600 new infections per day without adding that this is only the tip of the iceberg and that we don't see the real figure due to insufficient testing, this is not only misleading but it gives people a false sense of security and thus contributes to producing a new wave of infections as people relax their protective measures and behaviours.

Oh and the fact that the health secretary, in the daily briefing of June 1, attempted to sweep 445 deaths under the rug and hoped that nobody would notice, that hasn't really helped to build trust. In case you missed it: the June 1 announcement had 39045 deaths including 111 new deaths. But the figure from the day before was 38489, so the difference was really 556. I tweeted about this while the briefing was still ongoing, but the govt. only "clarified" afterwards that the missing 445 deaths were "historic" ones that they had not included in the daily toll. As I haven't seen details of when these deaths happened, I'm not including them in my calculations. So I am now having to substract the 445 from the total each day for a week to get my rolling average right.

I have a nagging suspicion that the people in charge (i.e. DC, presumably) actually want the second wave to happen now. I reckon their calculation is that we got through peak one within three months, with 40k deaths, and without a total collapse of the health system. Give it four or five more rounds like this, they're thinking, and we have the infection numbers required for possible herd immunity. Fatal flaws in the argument are, of course,
1) we don't have confirmation that people are really immune after they have had the virus
2) running wild in such a huge host population, the virus could evolve into something else that may be more difficult to manage and that may not be covered by immunity produced by the initial version;
3) as I've calculated on March 13, when Vallance brought up herd immunity, this strategy would produce 400,000 avoidable deaths from Covid-19 plus additional ones from the impact it has on the health system.

But after the political fallout of the last 7 days it's clear that the govt doesn't care how many more people die. The important thing for them is to get back to their ideology-driven programme, including Brexit, privatisations etc.

In a way, it is understandable that they were caught out by the pandemic. The idea that a government might care for the wellbeing of the people was never ever on their radar, never mind their agenda.

Some recent pieces from the media



How can any scientists stand by this government now? Richard Horton wondered in the Guardian, after the scandal around Cummings' breach of quarantine. I've been wondering that for a while, which is why I now avoid to refer to the govt muppets as scientists, and have put scientists in quote marks above.

Also, read anything by Devi Sridhar that you can get hold of (not only in the Guardian, there have been pieces in other papers as well).
