Courageous. Indomitable. Erudite. Intelligent. Humane. These are only a few of the adjectives we could apply to Nawal El Saadawi. It’s one thing to be a feminist on a western university campus. Try your faith in somewhere like Egypt if you want to see what its application is really like. Because she did.

Born in a family of nine children, in a culture whose prevailing ethos was summed up by her own grandmother as “one boy is worth fifteen girls” she managed to qualify as a doctor before setting out on a lifetime of writing, political activism and public health. On the way she managed to upset just about every ruler of Egypt. Nasser, Sadat, Mubarak, Morzi- secular or Islaamist, she rubbed them up the wrong way with equal gusto. Read her obituary by Sarah A Smith in the Guardian * below, but do see that as a place to begin, not end, this remarkable life.

Those who have lived comfortable lives, where beliefs can more more like hobbies or career vehicles, or who imagine their lives ruined by a failure to acquire the very latest Armani suit, should take heart. Because there are people who surpass us in intelligence,bravery and imagination, and it will be them who save all our lives.

Ask the average man in the street “Oi-mate-what’s the antimatter?” and he’d probably tell you that antimatter is a particulate wave-particle phenomenon, obeying the laws of quantum mechanics exactly as matter does, except it’s negative. If pushed, and he had time to spare from, say, putting up a bit of scaffold or clearing your rubbish bins, he would probably quote the well known Schrodinger equation, which says it all as far as we’re concerned:

or to put it layman’s terms:

_{reproduced courtesy of wikipedia}

Now that’s cleared up, let’s get to the point. Which is that anti matter is the direct opposite of matter. When they meet they mutually annihilate. With a huge bang. Which could be an enormous source of energy. Or a great new weapon to fight baddy aliens. The problem is finding it. Because to make even a tiny sample is incredibly tricky and expensive, and it only lasts for about one million billionth of a microsecond.

All of which raises a problem. If antimatter and matter are completely equal and symmetrical they must have been present when the Big Bang went off, right? Which must must have left equal amounts of both scattered around the universe, like old chips from a carelessly-discarded take away meal. Except it isn’t like that. Everywhere you look, it’s about 99.99999% matter. So have we got it wrong about antimatter? Or the big bang? Or what? That excellent web site Live Science has a great take on this at number #5 on the link below-and there’s a few more headbreakers as well. Enjoy.

Welcome to our weekly collection of things we thought were good, but didn’t have the space to cover in bigger pieces.

Greening the cities If we are going to survive at all, we need to make our cities much much greener. There are enormous ecological bonuses in refurbishment, if it’s done correctly. Here Phineas Harper of the Guardian discusses exciting new ideas from those prize winning Parisiens Anne Lacaton and Jean-Phillipe Vassal

Immunity-don’t follow the herd About a year ago there was an enormous buzz around herd immunity, and how it would protect us from Covid-19 wihout the need for lock downs and vaccines. We at LSS always had our doubts. However Nature seems to have shot that fox once and for all. Read this,if you dare

Even with vaccination efforts in full force, the theoretical threshold for vanquishing COVID-19 looks out of reach, say scientists who are modelling the pandemic’s progress. Most estimates had placed the threshold at 60–70% of the population, but several factors seem to be pushing it up:

• Authorized vaccines can prevent people from getting sick with COVID-19. But it is still unclear to what extent they block infection and transmission. If vaccines don’t prevent SARS-CoV-2 from spreading, then many more people must be vaccinated to achieve herd immunity.
• A perfectly coordinated global vaccination campaign might have wiped out COVID-19, but the roll-out is wildly uneven. For example, Israel is closing in on the theoretical herd-immunity threshold, but its neighbours Lebanon, Syria, Jordan and Egypt have yet to vaccinate even 1% of their respective populations. This leaves pockets of vulnerability where the disease can surge and then spread.
• There are no authorized vaccines for children, so most adults would need to be immunized to achieve herd immunity.
• We’re in a race with new variants of SARS-CoV-2 that might be more transmissible and resistant to vaccines. A new variant could undo our progress.
• It’s not yet clear how long naturally acquired immunity to SARS-CoV-2 infection lasts, but it’s probably not forever. As immunity wanes, people become susceptible to reinfection and no longer contribute to herd immunity.
• The herd-immunity threshold gets higher when people relax their vigilance. “The vaccine is not bulletproof,” says biomedical data scientist Dvir Aran. Imagine that a vaccine offers 90% protection: “If before the vaccine you met at most one person, and now with vaccines you meet 10 people, you’re back to square one.”

So what does the future look like without herd immunity? The spectacularly speedy development of vaccines that reduce hospitalizations and deaths still implies a hopeful outcome. But in the long term, scientists think COVID-19 might become an endemic disease, much like influenza.Nature | 10 min read

Lightning never strikes twice Lots of planets moons and asteroids seem to have some of the conditions for life-but why did seem to have kicked off only on earth? One theory is that lightning strikes gave our ancestral molecules the necessary push. Seems a bit like those old Frankenstein films, doesn’t it? Here’s The Conversation with Benn Hess and his pals.

We too have an enormous reading programme this weekend, gentle readers. It’s the sign of an open mind. So let’s all get on with it-now!

Let’s get in a time machine and fly back exactly fifty years. It’s Friday 19th March 1971. The year that Britain will vote to join the fledgling EEC. Decimal money has arrived. Most people are relieved to get their letters and parcels back after a six week postal strike. Imagine you had just bought your brand new executive home on the outskirts of London, and were about to receive guests for a housewarming party, where doubtless you would discuss the above, and many other issues. But what would you have served?

If you hadn’t lined one up, you could rely on one of your guests to show up with a Watneys Party Seven. This was a large can which held seven pints of cheap beer and was designed to slake thirsts all night. Watneys , brewers of the famous red barrel were incredibly succesful at this time. Yet the real ale boom of the1970s was about to cover their brand names in obloquy and by 1979 they were no more.

Ladies (it was a less equal and enlightened age, remember) might have preferred Babycham. This was a cool light sparkling perry which had taken the 1960s by storm, and would not go into decline until the late seventies, when it looked to be going the same way as Ben Truman, cheap aftershave, and the British Motor Industry. Luckily for mankind, die hard enthusiasts kept this one on life support, and recently modest increases in sales have been reported.

Elsewhere in the room a new beast was stirring. Before the 1970s, the further you went down the social scale in Britain, the stronger was the regrettable assumption that drinking wine was somehow foreign, an unusual practice associated with those whose jobs were considered to be slightly -er-unmanly. Yet the sophisticated crowd (those who had been on a 10 day package holiday to Alicante) were bringing back exciting tales of wicked foreigners and their strange goings on-and wanted more. Up sprang a whole range of bottles with funny names like Hirondelle, Blue Nun, Black Tower, Mateus Rose– to cater to the tastes of this elite segment who knew, in the words of the old song “the future belongs to me!”

No seventies evening was complete without nibbles. (canapes were something you put over the patio when it rained) First there was The Snack with No Name. This comprised a single cocktail stick bearing a square lump of cheese and another of pineapple. Ubiquitous throughout the 1970s, they were abolished by Act of Parliament as one of the first actions of the Thatcher Government in 1979, and were never seen again. Peanuts came in one form only-salted. Of crisps, there were but three-salted, cheese and onion and prawn cocktail. Talking of which, it was the height of sophistication to put real prawn cocktail into hollowed out advocados-and assure doubtful guests that you did not own a cat.

So now lets drop the diamond stylus of our new Decca stereo on the first of tonights selection from the Hit Parade. It’s Resurrection Shuffle by Ashton Garner and Dyke. Coming up are Bridget the Midget by Ray Stevens and My Sweet Lord by George Harrison. But best of all, the number one sound. Hot Love by T Rex. We feel sure the publishers will not mind if we quote a line from its sophisticated, almost Wildean lyrics, and leave you to enjoy the weekend

She ain’t no witch and I love the way she twitch, oh ho ho (there’s a link below)

Happy 1971

Even before the release of Frank Sinatra‘s immortal classic Come Fly With Me, we at LSS have always been staunch fans of aviation. It’s not just the hackneyed cliches about business and pleasure, important though these may well be. It’s the way that planes have made the word smaller, forcing even the most inveterate xenophobes to at least admit that other people may actually exist-which is a lot.

The trouble is that old skool planes are noisy, intrusive and unbelievably polluting. Yes the industry is trying to work with governments to clean up its act. But it’s proving really tricky and we would hate to find a juncture where one had to choose between giving up the connectedness of flying in order to save the planet. Now a company called Faradair thinks it may have found a way around the dilemma. Writng in the Guardian, * Colin Tennant expounds on a genuinely exciting plane development called the BEHA (bio electric hybrid aircraft). It’s a lovely coffee break read.

For those with only time for an espresso, the facts are these. It’s got three wings, takes off on electric motors, cruises on biofuels at 230 mph (370km). It can take people or cargo, and can get in to all those pesky short runway inner city airports without waking all the residents. Colin’s piece has lots,lots more including lots of good pictures.

For us at LSS there are several learning points. Firstly really good imaginative thinking can solve problems. Secondly, it’s always a good idea to use transitional technologies like hybrids when you make a change. As in automotives, it’s much easier to go from petrol to electrics via hybrids, rather than trying to make it in a single jump. And from an English point of view-why, oh why, does yet another manufacturer with a good idea still have to complainn about lack of Government support? We bet the story would have been very different in South Korea.

But let’s end on a high, not a low. Hats off to Faradair and its brave chief exec Neil Cloughley. We wish them happy flying and a fuel order book.

Well no, he couldn’t, as all the pictures of him prove. But could a Neanderthal have been Leonardo da Vinci? Ah, that’s a different story. Up to now, the general consensus is that only modern humans, Homo Sapiens, created art. Now a new book by Professor Tom Higham of the University of Oxford, suggests that Neanderthals and other early types of human may have been artistically minded as well. At least, they could learn art from modern humans, even if they didnt invent it. We link to Dalya Alberge in The Guardian below. * But we want to go further.

There’s been hints and suggestions about this idea floating around for years . So to throw you all some more red meat, we link to a piece in National Geographic which gives some fine leads on the artistic accompishments of our much-disparaged cousins. * And New Scientist think that the mysterious Denisovans might have warmed to the Royal Academy Summer Show-assuming you could bring them back to life and safeguard them from Covid. All well and good, we hear you say- these were very modern types of humans, with brains as big as our own. Why, we even bred with them. But can we go back further. Evidence is scant, tantalising and of course open to interpretation. But there are intriguing hints that even Homo erectus may just, might, maybe have been making symbolic sketches on things as much as 500 000 years ago. See wikipedia link * below.

In which case, we think it is all rather moving. Art is sometimes produced in desperate circumstances. But the lives of early prehuman ancestors must have been desperately nasty, brutish and short. To think of one of them producing anything symbolic, and meant to last, is fascinating indeed.

At present, the most succesful club in the English Premier League is Manchester City. Of their 30 matches, so far they have won 22, scored 64 goals, conceded 21 and have accumulated 71 points. They lead their group in the European Champions League. They are feared and respected by all their rivals for the persistent quality and efficiency of their play. In the last twelve years they have becoame a world brand, attracting a wide following and major sponsorship.

Who are the people behind such success? If you want to know more you could google the owner, Sheikh Mansour bin Zayed Ali Nahyan,who is from the United Arab Emirates. The manager Pep Guardiola, a Spanish citizen who self identifies as Catalan, seems also to have had something to do with it. There seem to be quite a lot of players too, who hail from places as diverse as Brazil, Spain, France, the USA, Portugal, Belgium,Germany, Argentina and England. And this is nothing unique. Their nearest rivals, Manchester United, have similarly diverse make up,and are themselves no strangers to the pursuit of excellence. We could name others from both England and other countries, but you’d stop reading. But you could ask this-would Manchester City have done quite so well if they had only English players?

The other day we were reading about the top discoveries in Science in the last ten years. * and one of the things that struck us was how like football it is. We won’t go through all ten, you can see the link below. But all of these breakthroughs came from international collaboration. Lee Berger‘s work on Australopithecus sediba had collaborators from the USA, South Africa, Switzerland and Austria. The work to produce an Ebola vaccine * took the best part of three continents* Probably the biggest thing on the list to affect our lives is CRISPR. You can read about the amazing efforts to develop this in our third link. * There are some really good graphics too. This is all the tip of the iceberg: most university science departments and research institutes are multinational and multicultural, because the best scientists, like the best footballers, can come from anywhere.

We at LSS understand the current trends towards group defence and national isolation. The need to belong to your own is a deep and primary human instinct. It is a natural reaction to the unjust and unequal ways in which globalisation has played out in recent decades. As a political idea, the new tribalism is sweeping all before it. But science has a way of leading to material and economic advance. In the medium to long term there may be a premium for those who somehow maintain the best scientific teams. And inevitably, that will mean the most diverse.

Diptheria was the terror of the slums of Victorian Britain. Stealthy, silent and deadly it crept through crowded insanitary tenements taking a horrifying mortality among the poor, especially their children. It started with a sore throat, but then temperature soared; as the bacterium Corynebacterium diptheriae ravaged its defenceless victim, dead tissue built up in an impenetrable membrane in the throat, leading to a painful death by asphxyation.

The years after 1945 saw a gradual control of the disease, through things like vaccines, antibiotics and the enforcement of housing standards. The move to a more low tax free market model after 1979 saw these advances go gradually into reverse, as investment in things like antibiotics tailed off and people were forced back into overcrowded flats and slums. Now there is good evidence that diptheria is back-and it’s hungry. Writing in The Conversation, Robert C Will and Ankur Mutreja of the University of Cambridge no less,descibe the alarming rise in antibiotic resistant strains of C diptheriae and the rising case numbers which are starting to cause alarm in many countries. We post links to both their piece and the Wikipedia pst. Warning: some of the medical descriptions and images in these links are not for the faint hearted.

This week’s round up only has one trope, knowledge-pickers-support your local zoo.

We remember many an argument from the nineteen eighties about zoos, and the well intentioned case from the other side. Animals should roam free. Captivity can foster psychological aberrations in animals, especially those on the intellgent side, like bears or cats. Animals are not to be gaped at, like waxworks in exhibitions. All true no doubt. But then as now, we live in an imperfect world where one highly armed, arrogant species is trashing the livelihood and existence out of every other, and pushing species after species to extinction. Without zoos, wild animals would not exist at all. A zoo is like an Ark, its keepers latter-day Noahs, desperately keeping their charges alive. Until a better day, when humanity has outgrown its infantile egoism, and large parts of our planet can be returned to nature.

The Zoological Society of London was founded in 1826. But thanks to the drop in visitors due to Covid, it may not see its 200th anniversary in five years’ time. Which is suddenly true of just about every zoo in the world. This would be a tragedy of indescribable proportions. Founded as an institution of scientific research, ZSL has always been at the forefront of new programmes of public education, conservation, breeding and animal welfare. Above all, ZSL pioneered new ways of taking animals out of bleak, functional cages and putting them into more natural surroundings. Opening a country branch at Whipsnade (1931) was not only good business-it was humane. Such environments are now de riguer in zoos whether urban or rural and of course led to the development of wildlife parks where animals roam nearly free.

Every zoo we have visited, from San Diego to Regents Park, is an education-in nature, architecture and humanity(they’re great for people watching). Being in England, we naturally put our local people below. But wherever you read this, please think of a donation for your local Zoological gardens. Because your grandchildren will thank you for it.

This week we want to celebrate two drinks which link Britain and the USA-whisky and bourbon. There are so many special relationships from hush hush security to blessed ties in marriage, including prominent families like the Churchills! That excellent book The Bartender’s Guide by Peter Bohrman gave us a few ideas, together with some of his tasting notes! Sadly,we can’t think of a theme to link all these delicious drinks-can you, gentle readers?

Prince Charlie “fruity dry drink for the evening” In a shaker, mix 1 measure (ms) of scotch. 0.75 ms. Drambuie, 2 teaspoonfuls (tsp) lemon juice and shake over ice. Pour to a cocktail glass and garnish wth a maraschino cherry. LSS says: well that’s pretty British!

Modern Girl spicy and dry In your shaker mix 0.75 ms bourbon , 2 tsp lemon juice, 1 tsp white rum, 1 tsp pernod, 1 tsp orange bitters. Shake over ice and pour to a cocktail glass, retaining the ice. Here comes the twist: squeeze the peel over the glass and use it for your garnish. LSS asks: can you think of any sassy American girls right now?

London Sour Fruity for any occasion Shake up 1 ms scotch. 0.75ms lemon juice, 0.75ms orange juice,2 tsp almond syrup, 2 tsp sugar syrup, all over chunky ice. Pour to a chilled cocktail glass and decorate with orange slice and cocktail cherry. LSS ponders: why is London sour?

Los Angeles fruity for a party Usual shake;1ms scotch 0.75ms passion fruit syrup,0.75ms lemon juice, 0.75ms pineaple juice,(there’s your five a day!) Big garnish on this one-slices of orange lemon and pineapple. Then add a touch of amaretto before she goes down the hatch. LSS observes: what a way to put your recent troubles behind you!

Royal Turkey fruity for summer In your shaker, over ice, add 1.5ms pineapple juice, 0.75ms bourbon. 0.75ms apricot brandy and 0.75ms gin. Shake and pour with ice to a highball or hurricane glass. Top up with ice cool lemonade, and garnish with a cherry. LSS speculates:could this be the name of the film, or the feedback?

For the record we have converted ounces to measures. Same thing. Thanks, Peter. If you want to benefit from his knowledge of over 1400 tasty drinks, and much beside, why not buy the book, which is to say:
