How Xenophobia Evolved

Overt xenophibia, used during the United Kingdom EU referendum.
Subconscious fear of infection may explain skepticism towards immigrants - ScienceDaily:

Xenophobia, one of the most irrational and destructive of human emotions, may have an evolutionary basis as a defence against infection, so argue scientists from Aarhus University, Upsala, Sweden in a published in American Political Science Review yesterday.

It is readily understandable how an aversion to excrement and putrefaction evolved, even evolving olfactory mechanisms which interpret the scents given off as repulsive. It is maybe not quite so easy to understand why some people at least overreact and are repelled by such signs of difference as physical deformity, birthmarks, skin colour and dress and yet these reactions are strong enough and commonplace enough to prevent successful integration of immigrant and refugee populations. The internal immune system, which attempts to cope with potential pathogens once they have gained access to our bodies, is supplemented by a behavioural immune system which helps prevent infection in the first place. The authors argue that this is an overreaction of a hypersensitive behavioural immune system.

Bonobos Refute Creationism!

Bonobo anatomy reveals stasis and mosaicism in chimpanzee evolution, and supports bonobos as the most appropriate extant model for the common ancestor of chimpanzees and humans | Scientific Reports

A paper published a few days ago is bound to cause a frenzy of denialism amongst creationists of all varieties and not just because of the length of its title. It appears to confirm what many people have suspected for a very long time - that the closest living relative of Homo sapiens is the bonobo, Pan paniscus.

In fact, in some respects the difference between humans and bonobos is less than the difference between different varieties of creationist. Creationism has been evolving and diversifying at warp speed since its invention in the 19th century in response to the discovery by science of biological evolution.

Now the differences are so wide it's difficult to find two creationists who agree on anything very much. They can't agree on such basic as whether evolution occurs at all, whether it occurs at a fantastic speed or slowly, how intelligent an intelligent (sic) designer would need to be, how well or badly the evidence fits old religious myths, whether there is any value in scientific evidence. They can't even agree on what shape Earth is, how old it is and whether it orbits the sun or the sun orbits Earth.

Does the 'Intelligent (sic) Designer' Hate Humans?

Scanning electron micrograph of a mass of Yersinia pestis, apparently thriving inside Acanthamoeba castellanii.
Plague Bacteria Take Refuge In Amoebae

For those who claim to subscribe to the intelligent (sic) design notion, parasitism is always embarrassing and not something they will normally bring themselves to discuss.

Take the battles medical science is having with the zika virus, the ebola virus, the malaria parasites, antibiotic resistent in pathogens, etc., for instance. If we assume for a moment that resistance to the various treatments is by design, not evolution, then one has to conclude that the designer is on the side of the parasites and is actively trying to out-manoeuvre medical science's efforts.

This study serves as a proof of principle that amoebae can support prolonged survival of Y. pestis in the environment.

Now we have the example of one of the most devastating disease organisms ever to hit mankind - the Black Death-causing Yersinia pestis - has been 'designed' to take refuge in the common amoeba which is abundant in soil and so provides a ready safe haven for Y. pestis to hide in.

Quietly and without fuss, and quite unintentionally, science again refutes creationism.

As it often does, in fact as it almost invariably does, another piece of scientific research based on observations of the real world, incidentally refutes the primitive superstition that the Universe and Earth were created by magic just a few thousand years ago. It also refutes the myth that there was a global flood even more recently, within the written history of civilisations such as those of Ancient Egypt, China and Northern India - who all seem to have forgotten to record it or even notice that there was anything amiss.

Homo naledi is only 250,000 years old – here’s why that matters | New Scientist

Creationists now have another problem and it's not just 250,000-year-old fossils in a 10,000-year-old Universe. It's even more fundamental than that.

First, a little background:

Homo naledi is from South Africa and, like another South African hominid, Australopithecus sediba, has a mixture of very human physical characteristics and some very primitive ones. With A. sediba, the primitive characteristics are enough to place it in the Australopithecus genus and so either an ancestor of the Homo genus or a cousin of one of our ancestors.

The Little 'Hobbit' is a Big Problem for Creationists

An artist's impression of Homo floresiensis based on recent research. Dubbed a human "hobbit", the species of humanoid was about a metre tall and died out about 54,000 years ago.

Origins of Indonesian hobbits finally revealed:

In its slow, methodical way, science shed a little more light on one of the mysteries of the evolution of the hominid family tree - the origin of the so-called hobbit, Homo floresiensis. The remains of H. floresiensis were found in a cave in Liang Bua in the Indonesian island of Flores in 2003. Initially, they were thought to be about 12,000 years old but later analysis has pushed this back to about 50,000 years.

The mystery isn't so much now how they came to be still living in isolation up to 12,000 years ago or why they are so small, being only about 1 metre tall, but where they fit in the hominid evolutionary tree and how they got to Flores Island.

Now a team from The Australian National University (ANU) has carried out a detailed statistical analysis and

New Book With A Difference

Some of the children of Fawler about to be given a ride by Fred Able, "The Donkey Man." About 1955-56.
Part of the reason I haven't been blogging quite so much in recent weeks is because I have been writing another books.

No, not another book about my usual subjects - general science, biology, atheism, religion and it's fallacies - but a much more personal book; a book about my childhood in rural Oxfordshire in the 1950s and 60s.

Of course, I cover my realisation that I was an Atheist and how my love of nature and science developed but I also cover life in general in a small agricultural hamlet. I talk about how important the countryside was to us as a playground and in particular how important the River Evenlode was to us children.

We spent the summer swimming, diving or lying half asleep with noses buried in fresh clover on the river bank and generally showing off to the local girls whose bodies were taking on strangely fascinating shapes. Some of the girls even began to wrap themselves in towels when they got changed. It was all very strange!

Give The Designer The Clap it Deserves!

Neisseria gonorrhoeae infection in the human endocervical tissue is visualized by immunofluorescence microscopy. Bacterial (red) colonization causes columnar endocervical epithelial cells to shed and lose the barrier function, which allows bacteria to enter the endocervical tissue. Frozen tissue sections were stained for immunofluorescence with specific antibodies to the apical junctional protein ZO1 (green) and N. gonorrhoeae (red) and the nuclear dye DAPI (blue).

Neisseria gonorrhoeae infects the human endocervix by activating non-muscle myosin II-mediated epithelial exfoliation

The Intelligent (sic) Designer really does deserve a big clap! It has come up with a brilliant solution to the problem it caused by its lack of a plan!

You see, the Intelligent (sic) Designer, that imaginary being so beloved of creationists but definitely not God because that would make it religion, not science, wants to make life unpleasant for humans (for strictly scientific reasons, obviously, and nothing to do with The Fall because that's religion) so it designed nasty little organisms like Neisseria gonorrhoeae to infect them when they had sex because it doesn't like them having sex the way it designed them to.

The trouble was, in a forgetful moment, it had designed humans so they could cope with nasty little organisms like N. gonorrhoeae and not be made sick by them. Now though, it has briiantly redesigned N. gonorrhoeae so it gets around the protection if gave humans.

In an open access paper published in PLOS Pathogens today, a team of scientists led by Liang-Chun Wang of the University of Maryland, College Park, have worked out how it got around the problem it had created. It does it by exploiting the very defence mechanism the Intelligent (sic) designer designed in the first place.

Layers of Evidence Against Creationism

There is science; and there is creationism. They have nothing in common.

Science looks at evidence and bases its opinions on it. When the evidence changes, science changes its mind. How could it be otherwise when the evidence is in charge? Creationism, on the other hand, starts with opinions as dictated by a holy book and then tries to force-fit the evidence around those opinions so they look sort of sciency to the scientifically illiterate and less like irrational superstitions and magical thinking. When that fails even for the gullible credulity of creationists, the fact are simply ignored and the main problem for creationists becomes how to get away with dismissing what can be plainly seen without looking too dishonest and deluded.

Parasites Bug Creationists

Cimicid Remains Found in Oregon Caves are Oldest Ever Found – Entomology Today

Newly discovered bat-bugs from the floor of a cave in Oregon are the earliest so far found - and it's bad news for creationists, again.

Parasites are a problem for creationists for number of reasons and not just that so many creationists are susceptible to parasitic frauds who sell them spurious confirmation of their superstition for large amounts of money. It's no accident that so many creationist charlatans are multi-millionaires while the people they live off are amongst the poorest of people.

How Evolution Works - Squirrels and Pine Martens

Population crash in an invasive species following the recovery of a native predator: the case of the American grey squirrel and the European pine marten in Ireland | SpringerLink

Sometimes, evolution can produce intriguing and unexpected results. At first glance it may be hard to see why introducing a predator can result in an increase in the population of a species. This is especially pleasing when the species benefiting is a charming and endangered species, the European red squirrel and the predator is an almost equally beautiful member of the stoat family, the pine marten.

So, having been away from blogging for a couple of weeks with other distractions, it gives me considerable pleasure to write about this open access paper, albeit from 2014, which reports just that from Ireland.

Observable Evolution Over Nine Generations!

Real-time divergent evolution in plants driven by pollinators | Nature Communications.

Until a few years ago, almost all creationists had no doubt at all; evolution simply didn't happen. All living things were created in a couple of days exactly as they are today. There was no debate; evolution didn't happen because it wasn't mentioned in the Bible and that was that.

This is still the position maintained by a large number of creationists who believe the world was created just a few thousand years ago, as we see it today, and nothing has changed since.

Noses Run Counter To Creationism

Investigating the case of human nose shape and climate adaptation | PLOS Genetics

Scientists believe they have uncovered evidence that the different human nose types are at least partly or even mostly adaptations to different climates as humans spread out from our ancestral homeland in Africa.

An important function of the nasal cavity and the nasopharynx is to humidify the sir before it reaches the lower respirator tract and the lungs.

Using 3D facial imaging, the team measured the width of the nostrils, the distance between nostrils, the height of the nose, nose ridge length, nose protrusion, external area of the nose and the area of the nostrils. They found the two measures: the width of the nostrils and of the base of the nose differed between different human populations by more than would be expected from genetic drift alone. They found a positive correlation between the width of the nose and the warmth and humidity of the climate in which the populations lived.

Unintelligently Designed Epigenenetics

Creationists, especially those who try to disguise their religious cult as 'Intelligent (sic) Design' and pretend it's science, seem to be getting themselves over-excited by the relatively new science of epigenetics.

It's easy to see why, given the abysmal ignorance which characterises creationism, because it superficially seems to challenge some of the basic principles of Darwinian evolution because it appears to open up the possibility that changes acquired after conception can be passed on. This is, of course Lamarckian, not Darwinian inheritance.

Given the creationist assumption that if they can show any science to be ever so slightly wrong in any way, the entire body of science if proven false and their primitive, evidence-free superstition wins by default, they grasp desperately at epigenetics like a drowning man grasps at straws and wave it in triumph.

How Science Works - Correcting Errors


Monarch butterfly (Danaus plexippus)



Tiger butterfly (Danaus genutia)
Monarch miscalculation: Has a scientific error about the butterflies persisted for more than 40 years? | Science | AAAS

How does a possible mistake in what was believed to be the number of chromosomes in the monarch butterfly validate scientific methodology?

Well, firstly, if you're looking for certainty, don't look at science - if you value certainty over truth, that is. Certainty and truth are not the same thing at all. The only certainty in science is that there are no certainties. Science is a human endeavour and as with all human endeavours the humans doing it make mistakes. Doubts, not certainties, are what drives science forward and the reason science continues to grow and develop and take us closer to a better understanding of the way things work.

By contrast, religion, and especially the extreme fundamentalist form we see in Bible-literalist creationism, depend on certainty and a complete absence of doubt. Allow in the slightest doubt; ask a difficult question and the whole thing could come crashing down and to make matters worse, the is no factual basis for those certainties so nothing neutral by which to alloy those fears and satisfy those doubts.

Once the doubts are there or the certainties have become uncertain, there is nothing holding it back. And fundamentalists know this, hence their refusal to acknowledge errors, even the glaring contradictions in the holy books. They can't be contradictions because the holy book is the source of all truth. How can they be contradictions?

In this paper a team led by scientists at the American Museum of Natural History, the City University of New York, and Fordham University, have shown that rock-dwelling cichlids of the genus Teleogramma are diversifying in a very sort stretch near the mouth of the Congo River in Africa. The final 200-mile stretch of the Congo River is exceptional in depth, speed, and turbulence, forming the world’s most extreme rapids.

Nasty Designer?

Parasitic worm may trigger mystery nodding syndrome | Science

Like all parasites, which have a ready explanation in terms of evolutionary biology, parasitic worms which make children sick and die present Intelligent (sic) Design advocates with special problems, not the least of which is one of creationism's own making.

The problem is that creationists presented with these especially nasty inventions of any assumed intelligence invariably fall back on 'The Fall' and say God allowed evil to enter the world because Eve sinned, so it's all our fault really. The problem for Intelligent (sic) Design advocates is that ID was invented as a concept to make creationism look like science so it could be inserted into American school science classes despite the 'Establishment Clause' and taught at tax-payers expense to vulnerable children.

How the Mammalian Ear Evolved!

Monodelphis domestica
A new developmental mechanism for the separation of the mammalian middle ear ossicles from the jaw | Proceedings of the Royal Society B.

Alternative creationist fact:
  1. The Theory of Evolution is in disarray because there is no evidence for it. It will be replaced by Intelligent Design any day now.
  2. There are no transition forms.

These are of course as true as Donald Trump's alternative facts, i.e. not true at all and made up to mislead people because the truth is too embarrassing. This paper shows the real state of evolutionary biology and shows how a clear evolutionary pathway from the reptilian ear to the mammalian ear may have arisen by a simple, single mutation. A team of animal scientists at the University of Illinois at Urbana-Champaign, King’s College London, and the University of Chicago have discovered, hidden in the development of opossums, a plausible evolutionary path that led from the simple ears of reptiles to the more elaborate and sensitive structures of mammals, including humans.

Anglicans Struggling to Adapt

Church of England General Synod votes to reject controversial same sex marriage report | The Independent

In a move which illustrates how the Anglican Church in Britain is struggling to keep up with changing social attitudes, the General Synod has voted to reject a report by the House of Bishops which called for continued opposition to and stigmatisation of same sex marriage.

While fully 73% of British non-believers see nothing wrong with same-sex marriage, only 50% of practising Anglicans share that view. However, this is a huge softening in attitudes as reflected in the same NatCen British Social Attitudes Survey which showed only 17% of Anglicans now believe same-sex marriage is always wrong compared to 53% in 1983.

Evolution of Innate Morality

Monkeys and dogs judge humans by how they treat others | New Scientist

Is your dog capable of moral judgements? Is it watching you and evaluating your trustworthiness?

According to a team of researchers from Kyoto and Hokkaido Universities, Japan, it might well be doing so.

Almost to a man or woman, theists will tell you that if gods provided us with anything, they provided us with morals. Neither Christians, Muslims or Jews seem to be able to understand how we could possibly have got morals from anywhere other than their holy book, revealed, so they claim, to mankind specifically to tell us how to behave and what rewards of punishments we could expect to ensure compliance.

The early universe sent out signals with information about its formation. All we need to do is look in the right place and in the right way to find these ancient signals. Scientists working at the University of Basel believe they have at last shown what we should be looking for.

The signals are tiny fluctuations in the gravity wave field. Although Albert Einstein predicted the existence of gravity waves they were only detected at the end of 2015. Already science is moving on to make use of this new technological ability and so to look further back into the formation of the Universe.

Best of Brexit Britain!

Here's a brilliant idea I've just pinched from Answers in Genes who got it from someone on Reddit (Is that still going?).

It solves lots of the historical problems with the United Kingdom of Great Britain and Northern Ireland, if only by shortening the ridiculously long name for a country - one of the longest on record and more a short essay than the name of a state. It also solves the problem of lots of people not being particular happy with the present arrangement and having various ambitions to belong or not to belong either to England or to the European Union. Some want in; some want out; some want both at the same time it seems, at whatever level you look at it.

The solution is the Union of Scotland and Ireland (both North and South) and the Kingdom of England and Wales.

Northern Ireland, which has always been a problem, both for Ireland and for England gets the best of both worlds. The Protestants, most of whose ancestors came from Scotland not England and so are mostly Presbyterian rather than Anglican only ever really had

Hypotheses, Experiments, Theories and Laws.

One problem debating science with creationists is that the latter are, almost by definition, scientifically illiterate, unless they are defrauding scientifically illiterate creationists for money by misleading them about the science.

So many debates, even those rare ones where the creationist is interested in learning, founder on some basic misunderstanding and confusion of terms. I'm even engaged with one at the moment who is either feigning scientific ignorance or is genuinely ignorant to the extent that he doesn't understand the difference between a definition, a hypothesis and a theory. I'll not bother to define 'definition' (which should be self-evident anyway) but the following is an attempt to define the terms 'hypothesis', 'experiment', 'theory' and 'law' as they apply to formal science.

Part of the problem is that science uses a slightly different but more precise meanings of ‘hypothesis’ and ‘theory’ to that used in vernacular speech. In the vernacular, hypothesis and theory are pretty much

Cooperative Evolution

Plant keeps moths captive inside its fruits for almost a year | New Scientist

Who ever imagined that selfish genes inevitably lead to mutually destructive competition? Well, by and large, of course, these are the same people who argue that atheist societies will be lawless hell-holes full of rapists and cutthroat murderers with no-one having any reason to be anything other than utterly selfish. Reality was never their strong point.

The rebuttal is of course the same: no such system could evolve because mutual destruction and selfishness produce fewer, not more, descendants. The fact that we observe neither of these outcomes in reality is evidence for the evolutionary process.

When Fascism Came to America

"When Fascism comes to America, it will be wrapped in a flag and carrying a cross."
Attrib. Sinclair Lewis


Has fascism come to America with Donald Trump?

The following fourteen characteristics of Fascism comes from Dr Lawrence Britt, who has examined the fascist regimes of Hitler (Germany), Mussolini (Italy), Franco (Spain), Suharto (Indonesia) and several Latin American regimes. His analysis is not without its critics, some of whom have a clear motive in not wanting Americans to recognise Fascism when it comes, but in broad outline it serves as working description of a typical Fascist regime such as Europe saw in the first half of the 20th-Century. (My thanks to Facebook user Robert D'Abehtynot for bringing it to my attention)

A Little More Nastiness From The Malevolent Designer?

Tales from the crypt: a parasitoid manipulates the behaviour of its parasite host | Proceedings of the Royal Society of London B: Biological Sciences

Sometimes the sheer malevolence of nature, if nature can have a personality, leaves one wondering what, if there could conceivably be some intelligence behind it, whatever sort of sadistic nastiness it could possible be that is so inventive in ways to be so hideously unpleasant. It beggars belief that there are not only people who believe this supposed intelligence is possessed by a real entity but that any entity this malevolent could be worthy of adulation, worship and praise.

The low-lives who breed dogs to put them in pits to fight to the death for the fun of it are paragons of virtue compared to any putative designer of nature given the hideous ways it seems to have found to entertain itself, all day and every day in millions of different ways.

National Secular Society - Government must not prop up the Church of England, says NSS

The UK National Secular Society has make strong representation to the UK Government that public money should not continue to be used to prop up the failing Anglican Church and its buildings, pointing out that, despite plummeting congregations and thousands of essentially redundant churches, the Church of England is a very wealthy organisation, having assets estimated at £20 billion!

Despite this wealth, since 2014 the government has allocated some £221 million for repairing and maintaining places of worship, the vast majority of which was spent on Anglican churches and cathedrals.

The representation by the NSS was made to the Department for Culture, Media & Sport which is coordinating the survey for the English Churches and Cathedrals Sustainability Review. The review was set up last March to consider the whole question of the sustainability of the very large number of virtually unused churches.

Weekly attendance at Sunday services has now fallen to 1.4% of the population and some 2000 churches have regular

Church of England is 'dying' and you should leave - Former chaplain to the Queen

After a few days away from blogging it is gratifying to be able to return to report signs of further disintegration of the Anglican Church. These became evident last week when the former chaplain to the Queen, Rev Dr Gavin Ashenden, resigned and urged others to leave the Church of England if they want to remain true Anglicans.

The Queen of England and Scotland is herself titular head of the Anglican Church so it's especially pleasing that her personal spiritual adviser is telling people they should leave her Church!

You know, if you listen to Christians, you would expect a country in which most people say they are not religious, 40% of young people say they are Atheists and non-one believes God created the world, to be a pretty grim, 'godless' place.

You should expect to see bands of marauding rapist, thieves and cutthroat murderers roaming the streets in an orgy of selfishness and greed with no regard for the sanctity of human life. The last thing you would expect to see would be peace, brotherly love, a high level of social responsibility and good neighbourliness.

Declining Church Weddings in Spain

Spain has to be one of my favourite countries and not just for the sun, sand and sangria.

But one thing that used to put me off was the overt religiosity. If you don't like public displays of piety don't go there in Holy Week (Semana Santa) - the week leading up to Easter. Whole town centres will be closed and antiquities made inaccessible because one church or another is having one of those bizarre processions where dozens of men in costumes carry immensely heavy tableaux depicting Jesus and Mary.

Was Human Intelligence Made Possible By A Virus?

Viruses in the genome important for our brain | Lund University.

Well no, perhaps human intelligence was not caused by a virus as such but according to new research, its evolution may well have been made possible by an ancient retrovirus which infected an early vertebrate ancestor.

In a blog just a couple of days ago, I explained the origin of the endogenous retroviruses (EVRs) which now form 5%-10% of the human genome, much of it believed to be junk. I also explained that some of it might well have been exapted for other purposes, just as you might expect of a lot of 'spare' DNA hanging around for tens, maybe hundreds, of millions of years.

According to CNN, President Rodrigo Duterte signed an executive order providing funds and support for modern family planning, in a bid to make it fully available to the poor by 2018. This comes at the end of a titanic 16 year battle with the Catholic Church which had seemed to have ended in victory for secularists and those campaigning for an end to poverty in 2012.

Something Good From Religion!

Just occasionally, something good can come from religion!

Take for example, something that you'll see everywhere in Lisbon, Portugal, and in most other Portuguese-speaking countries - the wonderful pastel de nata or custard tart!

You see them everywhere in Portugal, in specialist shops and cafés and street vendor's vans. They are consumed in vast quantities and not just by tourists experimenting with local cuisine but by the Portuguese themselves as snacks and treats and just because they are sublimely delicious, glorious in the mouth and very, very moresome. Eaten warm, they are a delight of crisp pastry case and lush, soft egg custard, often flavoured with a light sprinkle of cinnamon and sugar. One is never enough!

Something Fishy About Retroviruses

Un-rooted phylogenies, estimated from a reverse transcriptase protein alignment.
Marine origin of retroviruses in the early Palaeozoic Era | Nature Communications.

Retroviruses are enough to induce extreme denialism in creationists because they can't be explained in terms of intelligent (sic) design, or design of any sort, but they can easily be explained by standard genetic evolutionary theory. In fact, they can only be explained by evolution.

Retroviruses are a class of related RNA viruses which, on gaining entry to a host cell, insert the DNA counterpart of their RNA into the genome, making themselves practically invisible to the normal antibody defences of the host. They can lay dormant for many years before being activated and, if they infect the germ-line cells, can be passed on to the next generation.

Bacterial Evolution Recorded in Byzantium

Byzantine skeleton yields 800-year-old genomes from a fatal infection | University of Wisconsin-Madison News.

A 30 year-old woman who died 800 years ago in what was Troy has unwittingly left us a snapshot of evolving bacteria and a serious infection in humans as it was 800 years ago.

The bacteria were recovered from calcified nodules found just below the ribs of a skeleton of the woman who died during pregnancy and who showed skeletal evidence of a hard, agrarian existence which may have made her vulnerable to infection. The recovered genome of two species of bacteria are of such high quality that they can be used to compare changes in one of the bacteria, Staphylococcus saprophyticus, in the intervening 800 years. The other bacteria, Gardnerella vaginalis, showed little change.

Abstract
Pregnancy complications are poorly represented in the archeological record, despite their importance in contemporary and ancient societies. While excavating a Byzantine cemetery in Troy, we discovered calcified abscesses among a woman’s remains. Scanning electron microscopy of the tissue revealed ‘ghost cells’, resulting from dystrophic calcification, which preserved ancient maternal, fetal and bacterial DNA of a severe infection, likely chorioamnionitis. Gardnerella vaginalis and Staphylococcus saprophyticus dominated the abscesses.

Early Neanderthals Had Religion Before Modern Humans?

Early Neanderthal constructions deep in Bruniquel Cave in southwestern France | Nature Letters.

This paper passed beneath my radar last August but it illustrates something rather nice about science - the way it continually challenges our assumptions and, if we are honest, causes us to change our minds and revise our understanding. It also shows that Neanderthals may have had religion before modern humans had left Africa.

The paper deals with the discovery in a French cave of artefacts which could only have been made by Neanderthals and a very long time ago.

Ask And It Shall Be Given

Arkansas State Rep. Micah Neal, Republican.
Asked for and was given $38,000 in bribes.
Evangelical Christian Arkansas Republican pleads guilty in $600K Bible college bribery scheme

A couple of Good Christian principles seem to have motivated evangelical Arkansas Republican State representative, Micah Neal. He appears to subscribe fully to the idea that:

Ask, and it shall be given you; seek, and ye shall find; knock, and it shall be opened unto you: For every one that asketh receiveth; and he that seeketh findeth; and to him that knocketh it shall be opened. (Matthew 7:7-8)

For where two or three are gathered together in my name, there am I in the midst of them. (Matthew 18:20)

Malevolent Design or Evolution?

Carla Cerami, M.D., PhD., is the lead scientist on the study and said its results reveal the relationship between anemia, iron supplementation and malaria risk.
Anemia Offers Stronger Protection Than Sickle Cell Trait Against the Erythrocytic Stage of Falciparum Malaria and This Protection Is Reversed by Iron Supplementation - EBioMedicine

I've yet to find an intelligent (sic) design advocate who doesn't believe their putative designer is anything other than the god they purport to believe in, whether they call it God, Allah, Dios, Gott, Yahweh or any other of the names for the god of the Bible and Qur'an.

It's fair to assume therefore that this putative intelligent designer, in the minds of its advocates, has all the characteristics they assign to their particular version of this god. This includes having made humans as it's special creation with everything else there merely to serve the needs of these special human creations. So this open-access paper presents intelligent (sic) design advocates with a special problem. If it was intelligently designed, there is no way these findings can be presented as anything more than a work of extreme malevolence and mendacious sadism.

Signals From Space - Keep Calm and Carry On!

Source of mysterious deep space radio wave discovered for the first time | Science | The Guardian

Scientists have identified the source of a pulse of radio signals first detected in 2016 of a type only known about since 2007.

The so-called fast radio bursts (FRBs) most probably came from a dwarf galaxy some 3 billion light years from Earth, so the pulse only began its journey when Earth was just a few million years old, maybe when life was just getting going.

But it's nothing for alien conspiracists to get excited over; nor is it anything for creationists to start to panic over. It almost certainly isn't a signal from some other intelligence in a distant galaxy. However, exactly what it is is still a bit of a mystery.
