UK courts recently allowed a teenager’s body to be cryogenically frozen, but the desire to preserve our dead for resurrection is nothing newWhen a judge’s decision to allow a 14 year old to have her body preserved through cryonics after her death hit the headlines, it prompted numerous opinion pieces on the rights of the dying and the dead and discussions about promises of life after death. But while the technology might be changing, these debates are age-old, as humans have long attempted to ensure their place in the afterlife, or avoid it all together.

60 years after the Clean Air Act, Londoners still suffer from air pollution. What can we can learn from two centuries of campaigns against city smog?

Throwing resources at science, technology, engineering and maths in England hasn’t worked. We need to reaffirm the importance of a more rounded educationAs a long-time maths teacher, the latest assessments by the Trends in International Mathematics and Science Study and Programme for International Student Assessment make for tough reading. They indicate that there is little evidence of real gains having been made in maths and science in England over the past four years.Related: UK schools fail to climb international league table Continue reading...

Fragment complete with fossilised bones and traces of muscles, ligaments and mummified-looking skin dates from around 99 million years agoA length of fluffy plumage discovered within a piece of amber has been identified as part of a dinosaur tail, offering new insights into the evolution of feathers.Around 3.7cm long, with chestnut-coloured feathers on the top and pale feathers underneath, the tail was found complete with fossilised bones as well as traces of muscles, ligaments and mummified-looking skin.

From dinosaur hunters to new dimension discoverers, the Local Heroes scheme will fund projects to celebrate and explore science across the UKThe Royal Society today announced the 15 successful projects that its Local Heroes scheme will fund. These grants go to small museums across the UK, from Orkney to Plymouth, to explore the lives and legacies of scientists with close connections to their communities.I was fortunate to be on the judging panel and to see the richness, variety and imagination offered by all the applicants. The funding is only up to £3000, which is not much for museums that are often already suffering cuts from local authority budgets, but the imaginative projects have great potential to intrigue, inform and inspire.

Ancient water channels in Morocco, declining Arctic sea ice and the US-Mexico border were among the images captured by European Space Agency and Nasa satellites last monthA bank of clouds covers East Java to the west, with a bright sun overhead casting shadows from the clouds along the ocean surface. Sunglint, an optical effect caused by the reflection of sunlight off the water surface directly back at the satellite sensor, exposes the waves created by the movement of currents in the ocean water. Internal waves are generated when the interface between layers is disturbed, such as when tidal flow passes over rough ocean floors, ridges, or other obstacles. The Lombok Strait, a relatively narrow passageway between Bali (west) and Lombok (east), allows flow of water from the Pacific Ocean into the Indian Ocean. The bottom of the strait is complex and rough, consisting of two main channels, one shallow and one deep. Because of the variation in water movement due to the complexity of the channels and ocean interface, the tides in the strait have a complex rhythm but tend to combine about every 14 days to create an exceptionally strong tidal flow. It is the combination of rough topography, strong tidal currents, and stratified water from the ocean exchange that makes the Lombok Strait famous for the generation of intensive internal waves.

The obsession with pedigree as an explanation for success and failure is just a present day form of narcissismAre the novelist Anthony Powell and the actor Danny Dyer related? The biology has yet to be checked, but the evidence is compelling. Spiritually, at least, these two are blood brothers, intimately linked. Both are entertainers, both are fans of the pithy putdown (Powell: “His mastery of the hard-luck story was of a kind never achieved by persons not wholly concentrated on themselves”; Dyer: “Mate, you look like an earthworm who’s whacked a hoodie on”). And both are raging snobs. For Powell, lineage was of paramount importance, Burke’s Peerage his favourite book. Between writing, he devoted his studies to his own ancestry. The pedigree of others determined his attitude to them, from aristo pals to the postman. For all, he endeavoured to trace their descent back as far – and as posh – as possible.Related: Who Do You Think You Are? review – arise, King Danny Dyer Continue reading...

The park engineers in HBO’s Westworld should probably be fired for some of the bad choices they madeHBO’s new Westworld series has spawned countless gigabytes of online discussion and speculation as its intricate plot has unfolded. The design of the robots, and of the intelligence that guides them, has attracted less comment. That’s a shame; when you dive into the construction of the park there are some very odd choices that are worth pulling apart.(Warning: spoilers ahead.) Continue reading...

New gallery tells stories of how maths underpins the worldIn 1818, the Foreign Secretary Lord Castlereagh sent a letter to all British consuls across the world, asking them to obtain examples of their local standard weights. At that time the UK had no universal conversion table between the many different systems of weights and measures used by foreign cities.It took two years for all 71 sets of weights to arrive in London, where they were put in two cabinets installed in the Royal Mint. When the measurements were compared with each other, the Mint discovered that almost every previous conversion table was wrong – and that for the previous century these errors had been costing UK traders dosh.

As the far-reaching Higher Education and Research Bill reaches the House of Lords, further amendments are needed to ensure it succeeds in its aimsPower – where is it located? How is it won and lost? On the face of it, Prime Minister Theresa May is the most powerful person in the UK. But she is struggling to “take back control” on behalf of the country because of the lack of unity on Brexit amongst her ministers. And now the shock result of the Richmond by-election is inducing panic among senior Conservatives, worried that they will not be able to convert a double-digit lead in the polls into a thumping parliamentary majority at the next general election.Former Chancellor George Osborne recently provided some candid insights into the power-plays that rumble through Whitehall as the government machine wrestles with the process of policy-making.

Google’s new Timelapse project allows you to see how anywhere in the world has changed in the last 32 years; from evaporating lakes to exploding cities, it’s a document of recklessnessThe image of the Earth from space is so seared into human consciousness that it is hard to conceive what it was like to live without the picture of our planet as a blue sphere that we all now carry in our minds.The first photographs of the Earth’s surface seen from 100 miles were taken in 1947. By 1968, the famous Earthrise image photographed by the crew of Apollo 8 framed our planet as a beautiful oasis in black space. Today, stunning and intensely informative pictures of the Earth’s surface are being taken from space constantly: so comprehensively, for so long, that Google has now created timelapses that show three decades of change.

Much like the president-elect, Ramesses II knew that bombast can sometimes outweigh truth. His tale of triumph at the Battle of Kadesh is a perfect exampleIn 1274BCE, near the Levantine town of Kadesh, a miracle occurred: Ramesses II of Egypt, isolated from his forces due to faulty intelligence, single-handedly destroyed a Hittite army. Out of the 2,500 chariots attacking him, not one survived. The pharaoh subsequently threw countless enemies into the river Orontes, only sparing the Hittite king after he begged for mercy. It was a mighty victory – and a mighty mix of fact and fiction.This version of events is found in two texts commissioned by Ramesses: the so-called Official Record and the Poem of Pentaur (named after the scribe of Papyrus Sallier III). After the Kadesh campaign, the pharaoh used these texts to portray himself as the archetypal glorious commander: feared by the enemy and protected by the gods. These works appeared primarily on royal architecture, such as the monumental temples at Abu Simbel, Karnak, Luxor and Abydos. Carved in stone, the inscriptions were designed for eternity, and the detailed reliefs accompanying them meant that even the illiterate majority could understand. Meanwhile, the Poem was also circulated on papyrus, allowing the story to travel rather than being confined to immobile monuments. Thus, Ramesses did everything to spread the word to everyone – from humble peasants gazing at temple walls to nobles enjoying court poetry. Continue reading...

Carbon dating of remains unearthed in Beckery chapel near Glastonbury indicate monastic life dating back to fifth or early sixth centuriesSkeletons excavated at a site near Glastonbury are the oldest examples of monks ever found in the UK, carbon dating has proved.The remains, unearthed at the medieval Beckery chapel in Somerset, said to have been visited by legendary figures such as King Arthur and St Bridget, indicate a monastic cemetery dating back to the fifth or early sixth centuries AD, before Somerset was conquered by the Saxon kings of Wessex in the seventh century.
