While I don't believe in Santa Claus, I am glad that the mad rush of trying to get everything done before xmas is over. I haven't managed to write any seasonal greetings or a legible end of year report, partially because I am changing my mind twice daily about whether to stick around or join the brexodus. One of several serious problems is that the death eaters are cropping up everywhere, so it's tricky to find a place where one might be safe from them.
Anyhow, my next hard deadline will be mid January, so plenty of time to catch up with various things that have fallen by the wayside ...
So have a good one of whatever you celebrate or don't. Personally, I am following way too many classicists on twitter, so I'm beginning to feel I should celebrate Saturnalia ...

After last week's salmon feature, I am sticking with fishy things. Preparing a future article on evolution, I had to look up my ancient feature pegged to the coelacanth genome and remembered I really liked it. The most mindboggling thought about this, as I noted in a blog entry back in 2013, arises from the fact that the coelacanth is one of the closest relatives of the lineage that conquered land and turned into tetrapods. Thus: "If you look at the tree of life from the perspective of the coelacanth, you'll find that mice, chickens and humans are closer relatives than herring or zebrafish, or anything that lives in an aquarium, and never mind sharks and rays. Try to get that into your brain if you're just a fish." Entirely logical but still mindboggling.
Oh well. Maybe I shouldn’t have given up the Harry Potter series in the middle of the goblet of fire. Now the death eaters are running rampant, and I don’t know what to do. Specifically: remain in the UK (and thus leave the EU) or leave the UK (and remain in the EU)? Very confusing all this. I think that generally, organisations claiming to speak for the 3 million EU27 citizens in the UK have been too craven advising people how to jump through the death eaters hoops rather than to keep open the option of packing up for brexodus.
Since the election, I’ve been changing my mind about it twice daily, so to get some clarity, I’ve made a spreadsheet for arguments for and against moving. Right now, the case against is looking stronger. It has laziness on its side, which is a strong motivator. Plus the fact that many perks we have come to appreciate in Oxford just can’t be replicated elsewhere. Plus the rather scary realisation that if we did move to Germany (or any other of the EU27 countries) the local branch of the death eaters might take over there in a few years (ie on the same timescale that a move would take) and we’d be back on square 1.
So I guess today’s plan is stay put but shed some ballast in case we have to leave. It may be different tomorrow though.
As Der Spiegel highlighted with its cover feature two weeks ago, Germany's once-mighty social democrats (SPD), with election results dropping into single figures, are now desperate enough to vote for a pair of leftwing outsiders for the new leadership. (While I may agree with the new leaders' views on some issues, it is clear that they would never have had a chance if the party was as strong as it used to be. And the idea of a job-sharing male/female leadership tandem, nicked from the greens, is also a symptom.) If that development echos the rise of Jeremy Corbyn in 2015, does that mean Germany will have a far right populist government in four years time? It could also happen in France, and in several other EU27 countries. Essentially the same crisis everywhere - centre left voters left behind by the Blairs Clintons, Schröders of this world when they rushed to embrace neoliberalism are now biting back by turning right. Not all of them, of course, but enough to tip over the old left-right balance.

PSA: science news is on holidays now - I won't need any new topics until mid January, so I can skip all that filter feeding ...
I don't often write about food, but one of the editors at Current Biology suggested a feature about salmon, and as there is a lot of interesting ecology in this, apart from the obvious commercial interest, I agreed to do it as an end-of year festive treat ...
Salmon enjoys an unbroken popularity as food around the world, leading to the rapid growth and global spread of its industrialised production. (Photo: PublicDomainPictures/Pixabay.)
In the early 00s, still, the young musician got a tin whistle starter kit as a present from her cello teacher, including a tin whistle in D with James Galway's signature on it and a 16-page brochure with Galway's method. I'm a little bit allergic to the pompous "the man with the golden flute" image that has been created around Galway, so I find it refreshing that he also bothered with cheaper instruments like the tin whistle at some point.
The book has the address of Rose-Morris & Co. - that's still the name of a shop in London, but I think back in the days they were also instrument makers, so they may or may not have made the whistle. The company history is here with all sorts of exciting instruments, but I find no reference to whistles.
For the video I've attempted to play the Muiñeira Freixido, a traditional tune from the repertoire of our Galician session, which fits exactly within the bottom octave of the whistle:
I enjoy playing whistles every once in a while, although I am not all too keen on the sound of this one. I'm sure better ones will cross my path. I often have this one in my bag when I go out to play, just in case somebody needs a whistle.

Plant researchers examine bread aroma: Modern and old wheat varieties taste equally good Bread baked from modern wheat varieties are just as aromatic as that baked from old varieties. However, differences exist between the breads from different wheat varieties -- and those that were grown in different locations. These were the findings made by a team of German and Swiss researchers under the leadership of Heinrich Heine University Düsseldorf (HHU) and the University of Hohenheim in Stuttgart.

Navigating land and water Centipedes not only walk on land but also swim in water. Researchers at Tohoku University, Swiss Federal Institute of Technology in Lausanne, University of Ottawa, and Hokkaido University with the support of the Human Frontier Science Program have, for the first time, decoded the flexible motor control mechanism underlying amphibious locomotion, or the ability to walk on land and to swim in water, in centipedes.

Last remaining glaciers in the Pacific will soon melt away The last remaining tropical glaciers between the Himalayas and the Andes will disappear in the next decade -- and possibly sooner -- due to climate change, a new study has found. The glaciers in Papua, Indonesia, are "the canaries in the coal mine" for other mountaintop glaciers around the world, said Lonnie Thompson, one of the senior authors of the study published today in the Proceedings of the National Academy of Sciences.

Last year's offering was a slightly darker affair, with calculations of the environmental cost of carbon emissions and details of all the many things that were and still are going horribly wrong in the world. Back then we had Bolsonaro joining the crew of the horsemen of the climate apocalypse, this year it may be the UK's very own horror clown.

The Cantigas de Santa Maria - 420 songs in mediaeval Galician (aka Galician-Portuguese) collected by Alfonso X. in the 13th century - are an important foundation of Galician culture, and one or two of them have been played (as instrumental tunes) at our Galician sessions as well. However, our harper who plays them from memory, had learned them without numbers or titles, so they were almost impossible to find.
I recently attended a seminar on the cantigas (the relevant paper is here), where I learned lots of things about their structures and storytelling. Also about the fundamentals - for instance, the images of musicians, like the one above, appear only in one of the four known manuscripts. Two others include illustrations relating to the stories of miracles told in nine out of every ten cantigas.
The seminar inspired me to look at the mystery of our harper's cantiga again and I discovered that the lovely database Cantigas de Santa Maria for singers has a forward arrow on the pages displaying the modern notation for each cantiga. Until now I had assumed that I had to access each one separately with several clicks each time, but in fact I can just flick through them. Which I did, and starting at number one, I found that the cantiga we play most often is actually number seven. Quick and easy - not sure if I'd have had the stamina to find it if it had been number 407.
So it's called
Santa Maria amar devemos
and here is a lovely version with karaoke text lines, so you can sing along (and unlike some other versions I found, the melody sticks very close to the version we play):
In other CSM news, I just acquired a big book of solo pieces for alto recorder (Altblockflötensolobuch by Barbara Hintermeier and Birgit Baude, Schott 2014), and that also contains two of the cantigas, namely
In terms of recordings, there are lots of them on YouTube, obviously. This channel has so many, it may well be all of them, but they are in no particular order and mixed with videos of other early music, so it's hard to tell. The ones I checked usually had the lyrics displayed in some form.
This video: Fiesta en el corte de Alfonso el Sabio combines recordings of some 14 cantigas by different artists with a large number of the musicians miniatures from the manuscript.
I have a CD by Ensemble Alcatraz, called Vision and Miracles (1988) which includes CSM 103, 333, 117, 34, and 42 along with an instrumental suite using several cantigas and some other medieval pieces.
The Dufay Collective has recorded a CD full of cantigas, which is called Miracles.
Estampie have recorded a few. No. 120 Quantos me creveren (the numbers ending in 0 are songs of praise as opposed to stories of miracles) is included in their "Best Of" CD (2007) and a few more are on their album Signum (2004) including Non e gran cousa (26), Non devemos (27) and Quen na virgen (this could be 186, 256, or possibly 59, 103, or 276 - I don't have this CD).
La Capella Reial de Catalunya have recorded a dozen cantigas with Hesperion XX and Jordi Savall, available on CD as "Cantigas de Santa Maria - strela do dia". I'm a bit confused as Amazon seems to think it dates from 2017, but since the millennium the ensemble has been known as Hesperion XXI, so I suspect it may be a rerelease of a 1990s recording. Oh, and somebody posted it on Youtube in 2013.

Whales may owe their efficient digestion _of wax esters_ to millions of tiny microbes
I had to add the wax esters into the title because without this it would be no news at all, as I'm fairly sure all mammals use microbes to help with digestion, and we've known that for a while. Also, I think I am developing an allergy against PR people's use of the word "tiny" with things like microbes and molecules.
Can Arctic 'ice management' combat climate change? According to a much-debated geo-engineering approach, both sea-ice retreat and global warming could be slowed by using millions of wind-powered pumps, drifting in the sea ice, to promote ice formation during the Arctic winter.
What is a scream? The acoustics of a primal human call
Reminds me of Jared Diamond's News and Views in Nature, back in 1997, with the title: "Aaaaaaaaaaaaargh,no!" (I've looked it up to get the number of repeated letters exactly right, without that it is hard to find) about why humans spend energy screaming rather than saving it to fight or escape. Back then, as I was writing science journalism in my spare time, I found it very inspiring to see you could get away with Aaaaaaaaaaaaargh,no! as the title of a piece in Nature.

This illustration shows the white dwarf WDJ0914+1914 and its Neptune-like exoplanet. Since the icy giant orbits the hot white dwarf at close range, the extreme ultraviolet radiation from the star strips away the planet's atmosphere. While most of this stripped gas escapes, some of it swirls into a disc, itself accreting onto the white dwarf.

Birds are shrinking as the climate warms
This is based on 40 years of collecting birds that ran into Chicago buildings ... so I could imagine alternative explanations.

Female fish can breed a new species if they aren't choosy about who is Mr. Right Fish will mate with a species outside their own if the male's colouring is attractive enough or if the female can't see him properly, according to new research.

How does language emerge? Researchers ... have tried to simulate the process of developing a new communication system in an experiment - with surprising results: even preschool children can spontaneously develop communication systems that exhibit core properties of natural language.

Today is the first day of the COP 25 climate conference at Madrid. The numbering really gets to me as it means that the international community has now been trying and mostly failing to agree on meaningful climate action for more than a quarter of a century. Personally, I've been aware of the issue for 30 years now - I remember it came up when we were preparing a Green party manifesto for local elections in late 1989. So if we had changed course then, we would see the benefits now.
As today also happens to be the publication date for issue 23 of Current Biology, I prepared a climate feature to mark the beginning of the conference, which is out now:

Some time back in the early 00s, I visited the PMT shop on Cowley Road, with a view to buy an electronic keyboard for the young musicians, but was left more confused than I had been before (I did buy a keyboard eventually but not on that day and not in this shop, will get back to that further down the line). So while I was wondering about touch-sensitive keys and pre-programmed accompaniments, I spotted an array of brightly coloured tambourines, and bought the yellow one as a displacement activity. I remember the shop assistant was amused by the plot twist.
It's from a US company called RhythmTech, and the range is called True Colors - looks like they still make them in 5 different colours and you can still buy the yellow one eg from Amazon (although I think it was a lot cheaper back then). Apparently the company's founder invented the crescent shape tambourine in an effort to have the centre of gravity of the instrument closer to the wrist and make playing less tiring, see the company's about page.
Although I haven't played it much (and certainly not enough to feel the pressing need for an energy-saving crescent shaped one), the tambourine has enjoyed its moments in the spotlight, as I brought it to the Misa Campesina, where the conductor used it a few times in the rehearsals and in the performance.
For the video I just gave it a quick shake - these things are really quite loud ...

The heat is on Climate change is reorganizing the life in our oceans in a big way: as waters warm, cold-loving species, from plankton to fish, leave the area and warm water species become more successful. So say an international group of scientists in the most comprehensive assessment of the effects of ocean warming on the distribution fish communities.
Forests face climate change tug of war Increased carbon dioxide allows plants to photosynthesize more and use less water. But warmer temperatures drive plants to use more water and photosynthesize less. So, which force, CO2 fertilization or heat stress, wins this climate tug of war? It depends on whether forests and trees are able to adapt to their new environment.
Forest farms could create market for ginseng, other herbs A transition from wild collection of herbs to forest farming needs to occur in Appalachia to make the opaque, unstable and unjust supply chain for forest medicinal plants such as ginseng sustainable, according to a team of researchers who have studied the market for more than a decade.
I am a great fan of the ZSL Edge of Existence website, which lists threatened species in major groups according to their EDGE (Evolutionary Distinctiveness / Global Endangerment) rating. I first discovered it when the reptiles list came out in early 2018. Later in the year, a piece of research analysing how fast mammalian diversity could evolve back after an extinction provided an excuse to have a closer look at the EDGE list of mammals.
Pangolins are hunted for meat as well as for their skin and scales, which are used in traditional medicine. They are therefore the most trafficked mammals, and the Chinese pangolin (Manis pentadactyla) may be the most endangered among them. (Photo: Ms. Sarita Jnawali of NTNC – Central Zoo.)
The chemistry of life fundamentally depends on light - without photosynthesis there wouldn't be much worth reporting. In contrast, chemistry as a discipline from fundamental research through to industrial applications doesn't use light all that often. The most common way of making things react is to heat them, add a catalyst, or even put pressure on. The science of light-induced reactions, aka photochemistry has remained a poor relation.
I am picking up signals that this may be about to change for a variety of reasons. We now have a much better understanding of how photochemistry works in natural systems so we could borrow an idea or two there. Also, in the quest to make chemistry more sustainable and "green", using light instead of high temperatures and pressures may often be a better solution.
I wrote a feature about various recent developments in photochemistry which is out now:
In the same issue, page 38, you can find my review of the book
Modern thermodynamics for chemists and biochemists
Oh, and it appears that I forgot to blog about my previous feature in C&I, which appeared in issue 8 and was about developing new kinds of magnets depending less on rare earth elements.

A remote control for everything small Special light beams can be used to manipulate molecules or small biological particles. However, these optical tweezers only work with objects in empty space. Any disturbing environment would deflect the light waves and destroy the effect. This is a problem, in particular with biological samples. Now, a special method was developed to calculate the perfect wave form to manipulate small particles in the presence of a disordered environment, even if they cannot be touched directly.

World's oldest glue used from prehistoric times till the days of the Gauls By studying artefacts that date back to the first 6 centuries AD through the lens of chemistry, archaeology, and textual analysis, french researchers have discovered birch tar was being used right up to late antiquity, if not longer.

Climate may have helped crumble one of the ancient world's most powerful civilizations New research suggests it was climate-related drought that built the foundation for the collapse of the Assyrian Empire (whose heartland was based in today's northern Iraq)--one of the most powerful civilizations in the ancient world.

The people responsible for this PR are definitely helping to crumble our civilisation and buiding the foundation for its collapse. One to keep as an example for writing workshops.

I only recently discovered the Ayoub sisters, when somebody shared Ya Mariam El Bekr somewhere. Looking up their back catalogue, I was intrigued by their adaptation of Boney M's Rasputin even though I generally feel that I have heard too much of this band in the 70s/80s and am not that keen to revisit their work.
I did however enjoy the string duo version of Rasputin, and then watched the making of video, and then wondered where the tune actually comes from. Turns out half of it is an old Turkish folk song (there are also Arabic versions of it, so I don't really know which of the two is the original).
The Turkish song is called Kâtibim (sheet music here) and I really love the Turkish / Urdu mashup you can watch here (just ignore the blatant Coke advertising).
The Arabic version is called Ya Banat Iskandaria, and searching for this title I found a lovely version for flute, harp, percussion, here.

Study finds sex bias in bird conservation plans After pairing up and raising chicks, males and females of some bird species spend their winter break apart. At the end of their journey to Central or South America, you might find mostly males in one habitat, and females in another. Yet conservation strategies have typically overlooked the habitats needed by females, putting already-declining species in even more peril.

I include quotes from the summary in italics in cases where the title alone doesn't reveal what the story is about. My own thoughts appear without italics if I have any.
A new Mammal Review study shows that the few remaining patches of lowland rainforest host the highest levels of lemur abundance for several species.

A solution to a hairy problem in forensic science In an effort to make hair comparison a more useful technique for investigating crimes, scientists at the National Institute of Standards and Technology (NIST) have developed a new way to dissolve hair proteins without destroying them. Once in solution, the protein molecules from two hairs can be analyzed and compared, yielding objective, quantitative results.

Jaw-some wombats may be great survivors Flexible jaws may help wombats better survive in a changing world by adapting to climate change's effect on vegetation and new diets in conservation sanctuaries. An international study, co-led by The University of Queensland's Dr Vera Weisbecker, has revealed that wombat jaws appear to change in relation to their diets.
Wombat skulls seem to be changing to match their diets.

conservation
To save biodiversity, scientists suggest 'mega-conservation' While the conservation of charismatic creatures like pandas, elephants and snow leopards are important in their own right, there may be no better ecological bang-for-our-buck than a sound, science-based effort to save widespread keystone systems. And the majestic aspens could be a perfect start for such an endeavor.

Scientists probe the limits of ice The smallest nanodroplet of water in which ice can form is only as big as 90 water molecules -- a tenth the size of the smallest virus. At those small scales, according to University of Utah chemistry professor and study co-author Valeria Molinero, the transition between ice and water gets a little frizzy.
I'm a chemist turned biochemist turned science writer, covering everything from nano to astro via bio. Also trying to make sense of my life in writing about family history. Playing wrong notes on a variety of instruments. Current craze: repairing violins and learning to play them too.
