Eta Aquariids have roughly a week of activity in May, though they are better seen from southern hemisphereDebris from the tail of one of the most famous comets of all - Halley's comet - will slam into the Earth's atmosphere this week, creating a meteor shower. The Eta Aquariids are not fantastically well placed for northern sky watchers, but they can still be rewarding for those willing to get up in the early hours.Unlike most meteor showers, which have a definite night of peak activity, there is roughly a week of activity during the Eta Aquariids, which are usually centred around the nights of 5-7 May.

Musk and Bezos are the heirs to a quasi-religious belief in tech salvation. The rest of us are stuck in the real worldIt's tempting to believe that tech billionaires' embrace of Donald Trump and the far right is a sudden rupture with the usual political ideology of Silicon Valley. Op-eds in the New York Times and elsewhere have made this case. Even Marc Andreessen, one of the billionaires in question, claims that this is what happened - he said that it was a change in the Democratic arty that pushed him and his fellow oligarchs into the arms of the GOP.Yet this is a serious misunderstanding of the situation. There wasn't a sudden shift in the politics of tech - it was a homecoming. While it's true that Silicon Valley has long supported Democratic candidates for political office - and that rank-and-file tech workers still vote overwhelmingly for Democrats - the fundamental ideology underpinning the culture of Silicon Valley's venture capitalists and CEOs has always had a far-right libertarian core. This is even true for Andreessen: while he likely believed what he said while he was saying it, his own words and actions make it clear that he wasn't giving an accurate assessment of his own motivations, much less anyone else's. His venture capital firm, Andreessen Horowitz, has long opposed government regulation of any sort that touches on their investments; Andreessen himself posted a techno-optimist manifesto" that, despite its claim to be politically neutral, promotes an authoritarian vision of unfettered power for tech oligarchs. He even lovingly paraphrases Filippo Marinetti, the co-author of the Fascist Manifesto. Continue reading...

Method of preserving 18th-century Austrian vicar has never been seen before, say researchersThe mystery of a mummy from an Austrian village has been solved, according to researchers who say it was embalmed in an unexpected way - via the rectum.Intrigue had long swirled around the mummified body stored in the church crypt of St Thomas am Blasenstein. The remains were rumoured to be the naturally preserved corpse of an aristocratic vicar, Franz Xaver Sidler von Rosenegg, who died in 1746 at the aged of 37, gaining the mummy the moniker of the air-dried chaplain".

Aluminium emissions from satellites as they fall to Earth and burn up is becoming more significant as their numbers soarRight now there are more than 9,000 satellites circumnavigating overhead, keeping track of weather, facilitating communications, aiding navigation and monitoring the Earth. By 2040, there could be more than 60,000. A new study shows that the emissions from expired satellites, as they fall to Earth and burn up, will be significant in future years, with implications for ozone hole recovery and climate.Satellites need to be replaced after about five years. Most old satellites are disposed of by reducing their altitude and letting them burn up as they fall, releasing pollution into Earth's atmosphere such as aerosolised aluminium. To understand the impact of these growing emissions from expired satellites, researchers simulated the effects associated with an annual release of 10,000 tonnes of aluminium oxide by 2040 (the amount estimated to be released from disposal of 3,000 satellites a year, assuming a fleet of 60,000 satellites).

The narrative of ancient tribes around the world regularly using ayahuasca and magic mushrooms in healing practices is a popular one. Is it true?Beginning in 2001, the Austrian anthropologist Bernd Brabec de Mori spent six years living in the western Amazon. He first arrived as a backpacker, returned to do a master's thesis on ayahuasca songs, and eventually did a PhD on the music of eight Indigenous peoples in the region. Along the way, he married a woman of the local Shipibo tribe and settled down.I did not have a lot of money," he told me, so I had to make my living there." He became a teacher. He built a house. He and his wife had children. That rare experience of joining the community, he said, forced him to realise that many of the assumptions he had picked up as an anthropologist were wrong.

Focus on overuse contributes to antibiotics reaching less than 7% of people with drug-resistant infections in poorer countries, say researchersLess than 7% of people with severe drug-resistant infections in poorer countries get the antibiotics they need, a new study suggests, with researchers warning that not only is this causing suffering and deaths, but is also likely to be driving antimicrobial resistance (AMR).With AMR forecast to cause 1.9m deaths a year by 2050, they are calling for urgent action, akin to the fight earlier this century to get HIV drugs to Africa's virus hotspots.

Wealthy nations are slashing funding for essential services such as the HIV/Aids response, but poorer countries cannot absorb the impact overnightCountries across the world are cutting aid budgets, abandoning the decades-old consensus that supporting health and development is both a moral duty and a strategic interest. But the end of aid cannot mean the end of global solidarity - because our global economy is stacked against low- and middle-income countries to such an extent that they simply cannot afford to respond to global crises alone.Developing countries are drowning in debt, facing interest rates up to 12 times higher than wealthy countries. When interest rates shot up after Russia's invasion of Ukraine, the global south was worst hit. Low- and middle-income countries now pay $4 (3) to the richest in the global north for every $1 they receive in aid. Thirty-four of Africa's 54 countries spend more on debt than on healthcare.

Donald Trump ignited a scramble that is transforming space from shared frontier to private asset - raising questions about law, equity and ethicsIn 2015, a rare moment of US congressional unity passed the Space Act - to mine asteroids as if they wereopen seams of ore and harvest planets like unclaimed farmland. Quietly signed by PresidentBarack Obama, it now reads as a premature act of enclosure: staking titles in a realm we scarcely understand. Though some expressed concerns at the time, it was justified by the idea of inevitable progress. Such naivety evaporated with Donald Trump. Space had been humanity's last commons, shielded by a 1967 Outer Space treaty. MrTrump declared it dead in 2020, signing the ArtemisAccords and enlisting 43allies, including the UK, in the legalisation of heaven's spoils. In March, MrTrump vowed to plant the stars and stripes on Mars - and beyond. The age of celestial commons was brief, if it ever began.A new report by the Common Wealth thinktank, titled Star Wars, warns that a powerful coalition - composed of private corporations, billionaires such as Elon Musk and Jeff Bezos, and neoliberal" thinktanks - is working to extend earthly ownership structures to space. The report's author, Durham University's Carla Ibled, calls it the transfer of shared resources into the hands of a few". The 1967 treaty bans state exploitationof space, but is vague on private claims -aloophole now fuelling a tycoon-led scramble for thestars. The aim is obvious: to act first, shape norms and dare others to object.Do you have an opinion on the issues raised in this article?

Intriguing advances hold out the possibility - but first we have to agree on what life' meansCreation of Life", read the headline of the Boston Herald in 1899. Lower Animals Produced by Chemical Means." The report described the work of the German-American marine biologist Jacques Loeb, who later wrote: The idea is now hovering before me that man himself can act as a creator, even in living nature."In fact, Loeb had merely made an unfertilised sea urchin egg divide by exposing it to a mixture of salts - he was not even close to creating life in the lab. No scientist has ever done that. But that ancient dream hovers today over the discipline called synthetic biology, the very name of which seems to promise the creation of artificial life forms. Take one of the most dramatic results in this field: in 2010, scientists at the J Craig Venter Institutes in Maryland and California announced they had made the first self-replicating synthetic bacterial cell".

Data indicates the Cosmos 2553 - which US officials claim is aiding Moscow's development of nuclear anti-satellite weapon - may no longer be functionalA secretive Russian satellite in space that US officials believe is connected to a nuclear anti-satellite weapons program has appeared to be spinning uncontrollably, suggesting it may no longer be functioning in what could be a setback for Moscow's space weapons efforts, according to US analysts.The Cosmos 2553 satellite, launched by Russia weeks before invading Ukraine in 2022, has had various bouts of what appears to be errant spinning over the past year, according to Doppler radar data from space-tracking firm LeoLabs and optical data from Slingshot Aerospace, shared with Reuters.

They can learn hundreds of words, count to five and read humans like a book, so why do we struggle to understand them? Scientists reveal the truth about our pets - and whether they ever feel guilty for eating our slippersThe thing that made me think my dog may be a genius was the word monkey. We'd developed a game where I'd hide her monkey toy - a sad, lifeless being, long lobotomised by my golden retriever puppy - and, when I asked her to find it, I realised she could differentiate the word monkey from other objects. A woman in the park had a similar story. On holiday in an unfamiliar cottage, she had misplaced the car keys. After hunting for them for over an hour, her dog, a border collie, overheard her and her husband talking about it, recognised the word keys" and immediately went and foundthem.So maybe my dog, Rhubarb, isn't a genius after all. Dogs, says Vanessa Woods, director of the Puppy Kindergarten project at Duke University in North Carolina, US, and writer of several books including Puppy Kindergarten: The New Science of Raising a Great Dog, can know hundreds of words for objects. Over 1,000, probably," she says. And actually it's more interesting than that, because they learn words the way children learn words, and that's not by repetition." Psychology professor Juliane Kaminski showed back in 2004 that a dog called Rico (another border collie), could learn, as children do, by inference - he didn't need to know the name of a new toy, he could work it out by excluding the toys he did know the names of.
