Researchers say a meteorite that crashed through the roof of a Hillsborough, New Jersey, home in 2024 contains unusually pristine evidence of salty fluids and organic chemistry from near the surface of a primitive asteroid. "A forensic study of the fragments revealed that they contained preserved bits from near the surface of a primitive asteroid, where it experienced concentrated salty fluids -- a process not previously known from this type of protoplanet world," said lead author and meteor astronomer Peter Jenniskens of the SETI Institute and NASA's Ames Research Center in California's Silicon Valley. Phys.org reports: According to paper co-author Mike Zolensky, a meteoriticist at NASA's Johnson Space Center in Houston, analysis of the Hillsborough meteorite found fragments that were more extensively altered by water on the meteorite's parent asteroid than is typically seen in CM2 carbonaceous chondrites. The analysis classified the specimen as a CM1/2 carbonaceous chondrite, an intermediate classification between petrographic types CM1 and CM2. [...] Zolensky and colleague JangMi Han found small salt-rich CM1 fragments within the Hillsborough meteorite, suggesting they originated from a near-surface region of the parent asteroid where liquid water evaporated and concentrated salts. They are now working to identify the salt minerals for comparison with similar phases found among samples returned to Earth from asteroids Ryugu and Bennu.
The high concentration of salt in briny fluids can potentially create molecules crucial to life on Earth. Brines allow phosphate to remain in solution and can catalyze chemical reactions between organics and precipitate minerals. "Isotope studies of carbon and nitrogen suggest that primitive carbonaceous chondrites, including CM types, delivered organic matter to the early Earth," said cosmochemist Queenie Chan of Royal Holloway University of London, England, and biogeochemist Nana Ogawa of the Biogeochemistry Research Center at the Japan Agency for Marine-Earth Science and Technology. "The Hillsborough meteorite contained 1.8% by weight of carbon and 0.07% of nitrogen, and had carbon and nitrogen isotopes typical for CM-type meteorites."
The meteorite contained a wide variety of soluble organic compounds, and its compositional range confirms that the Hillsborough meteorite was more altered by water than most other CM-type meteorites. "A high fraction of compounds were the product of organic chemistry with minerals," said organic mass spectrometry specialist Phil Schmitt-Kopplin of Technical University Munich. "We do not know if these magnesium organic compounds were contributed by brine chemistry or were simply left over from earlier impact shock processes." In living organisms, organometallic compounds are found in blood and used in photosynthesis. Among the soluble organic compounds were many amino acids, similar to those found in more moderately altered CM2 chondrites.
Astrobiologist Danny Glavin of NASA's Goddard Space Flight Center in Greenbelt, Maryland, and his team in Goddard's Astrobiology Analytical Lab concluded that the delivery of amino acids, carboxylic acids and other soluble organic molecules by CM-type bodies may have contributed to the prebiotic organic inventory that preceded the emergence of life on Earth. Their analysis suggests the complex distribution of amino acids observed in the Hillsborough meteorite formed within the parent body, likely assisted by brine fluid chemistry.
The findings have been published in the journal Science Advances.

BERLIJN (ANP/BLOOMBERG) - Duitsland wil subsidies voor hernieuwbare energie afbouwen in een ingrijpende herziening van het financieringssysteem. De reden is dat de groeiende productie van zonne-energie steeds meer druk legt op het Duitse elektriciteitsnet.
Vanaf 2027 moeten nieuwe projecten voor hernieuwbare energie steun krijgen "op een manier die zowel de markt als het energiesysteem ten goede komt", staat in een wetsvoorstel van het ministerie van Economische Zaken. Dat betekent dat projecten meer steun moeten krijgen als ze inspelen op de vraag naar elektriciteit en de drukte op het elektriciteitsnet niet verder vergroten. Vaste terugleververgoedingen voor nieuwe installaties worden volgens het voorstel geleidelijk afgebouwd.
De maatregelen kunnen investeringen in wind- en zonneprojecten op land afremmen. Ontwikkelaars hebben daar al te maken met hogere kosten en dalende inkomsten door ongunstige stroomprijzen.
DEN HAAG (ANP) - De politie heeft vier verdachten aangehouden nadat vrijdag een drugslab werd aangetroffen in de Meidoornstraat in Den Haag. Vrijdagmiddag werd in de woning al een 39-jarige man uit Den Haag aangehouden. Hij zat "onder de vloeistoffen" en werd naar het ziekenhuis gebracht. Later werden nog drie andere verdachten aangehouden, meldt de politie zaterdag.
Het gaat om een 34-jarige man uit Voorburg, een 44-jarige man uit Den Haag en een 71-jarige man uit Leiden. De politie verdenkt hen van mogelijke betrokkenheid bij het drugslab.
De politie doet buurtonderzoek en vraagt omwonenden die iets verdachts hebben gezien zich te melden.
KROKSTADELVA (ANP/DPA) - Vanwege de grote brand in het Noorse Krokstadelva zijn zo'n vierhonderd mensen geëvacueerd, zei burgemeester Kjell Arne Hermansen zaterdag tegen het Noorse persbureau NTB.
Volgens de hulpdiensten is het vuur nog niet onder controle, maar is het risico op verdere verspreiding beperkt. De brandweer is met onder meer blushelikopters bezig om het vuur te blussen.
Door de brand zijn meer dan honderd huizen verwoest. Er zijn geen meldingen van mensen met ernstige verwondingen.
DEN HAAG (ANP) - Op verschillende wegen naar Zuid-Europese vakantiebestemmingen is het erg druk met vakantieverkeer. Het loopt vast op de gebruikelijke punten waar het elke zomer filerijden is, zegt een woordvoerder van de ANWB.
In Frankrijk doen vakantiegangers er op de A7 tussen Lyon en Orange uren langer over. Vooral bij Valence staat het vast. Automobilisten in Duitsland staan in de file op de A8 van München naar Salzburg, tussen Neukirchen en de grens met Oostenrijk.
In Oostenrijk doet verkeer op de A11 van Salzburg naar Villach er langer over en is er verderop vertraging voor de Karawankentunnel, op de A11 van Villach naar het Sloveense Ljubljana.
Zwitserland en Italië
Op de A2 tussen de Zwitserse steden Luzern en Chiasso zitten de knelpunten voor Altdorf, voor Amsteg en voor de Gotthardtunnel.
Bestuurders in Italië komen in de file terecht op de A14 tussen Bologna en Imola, onderweg naar Rimini.
New Zealand 40-21 Ireland
Hosts unbeaten in 32 years at Auckland venue
Andy Farrell rued an error-strewn display after Ireland suffered a 40-21 defeat to New Zealand in round three of the Nations Championship.
The All Blacks scored four first-half tries through Patrick Tuipulotu, Ardie Savea, Will Jordan and Asafo Aumua en route to stretching their remarkable unbeaten run at Eden Park to 53 Tests. Jack Conan crossed for Ireland in a punishing first half before Joe McCarthy and Hugo Keenan went over in an improved second period, with Sam Prendergast slotting all three conversions.

For half a century, Donald Trump has performed a public high-wire act based on high-stakes risks and shattering time-honored norms to get what he wants.
The approach has paid off handsomely, helping him survive multiple bankruptcies to reach billionaire status and numerous legal and political scandals to be elected US president twice.

James Cameron loves tough female characters. That seems like a given now, after three Avatars and two particularly muscular arms belonging to Linda Hamilton in Terminator 2. Even the lushly romantic Titanic is about a supportive, sweet-natured boyfriend lending his love the extra smidge of strength she needs to live a rich and iconoclastic life without him, until she’s freely chucking diamonds into the sea at 100 years of age. But in Cameron’s 1984 de facto feature debut The Terminator (after a Piranha sequel that he attempted to disown), T2’s Hamilton is stalked and appropriately terrified by Arnold Schwarzenegger’s slasher-like killer robot. She’s a great character who gets majorly pumped up for the sequel in 1991. By then, Cameron had plenty of practice: he had already written and directed Aliens, maybe the best pumped-up sequel ever made, which turns 40 this week.
Ellen Ripley, introduced as the warrant officer onboard the ship Nostromo in Ridley Scott’s 1979 sci-fi horror picture Alien, is already a great character by the end of that film. But while the anecdote about James Cameron pitching a sequel by appending a dollar-sign to Alien’s title, concisely showing what a simple pluralization could do, has perhaps overtaken the buffing up of Ellen Ripley in the most-circulated lore about this movie, she’s really the first subject of Cameron’s great plussing. Without betraying the simplicity and resilience of her character in the first film, Cameron reintroduced Ripley as a survivor, landing on Earth almost 60 years after the events of the earlier film. (In a deleted scene restored in the film’s longer special edition, Ripley even learns that her daughter has died in the interim – as an adult, given that Ripley was in cryosleep for decades.)

Born in Sydney, Australia, to an Italian father and Australian mother, Natalie Imbruglia, 51, joined the cast of Neighbours at the age of 17. In 1997, she released her debut album, Left of the Middle, which gave her the global hit single Torn. She releases her seventh studio album, Algorithm, on 4 September. She lives in Oxfordshire with her son.
What is your greatest fear?
As an Italian, tinned spaghetti. As a child, I was once served it at someone’s house. It was quite frightening.
Annual lectures will discuss work of writer and campaigner who ‘revitalised the anti-slavery cause’ in Britain
He was one of the most important figures of his time, an author, orator and American statesman who was born enslaved. But some of the most important years in the civil rights leader Frederick Douglass’s life were spent in Britain.
This month marks the 180th anniversary of a series of lectures Douglass gave in Manchester, speaking at venues across the region.

I’m still getting my head around the 2007 photo of Lionel Messi, 19, bathing Lamine Yamal, four months, for a Unicef calendar shoot.
Sid Lowe has done some digging to find out how it all came out …
The photograph was taken around Christmas 2007. Sport newspaper was putting together a charity calendar on behalf of Barcelona and Unicef, a studio set up in the away dressing room at the Camp Nou. Each player had a month and appeared with a child. Ronaldinho, the star, was July. Messi was January. Lamine Yamal was four months old. His mum, Sheila, had put him into a draw to take part. Monfort got the idea the night before when bathing his daughter, taking a plastic tub and a rubber duck with him. Although the baby was tiny and Messi was timid, with Sheila’s help he got a shot he was happy with.

Researchers develop laser technology to test drinks for methanol. Adelaide University researchers have developed a way to use lasers to test closed alcohol bottles for methanol, which kills hundreds of people every year.
Researchers have developed laser-based technology that can detect chemicals like methanol, which killed two Australian teenagers overseas in 2024, without opening drink bottles. Thousands of people suffer from methanol poisoning each year, while hundreds die, including teenagers Bianca Jones and Holly Morton-Bowles, who died from tainted drinks in a Laos backpackers hostel. Methanol is a highly toxic alcohol that, when broken down by the human body, turns into formaldehyde and formic acid.

Why Captain Disillusion Is Still The GOAT (SLYT; 31:55), is an interview with Alan Melikdjanian that goes into the process of creating Captain Disillusion's videos. With bonus trick reveal for one of his recent-ish videos.
The amount of work and care Alan puts into his videos is always impressive. Even a quick connecting shot or gag often hides a lot of work. He's been on YouTube for a long time, and was featured here a few times previously (2008, 2016, 2021). Every video always with the same high quality standards. On his channel he also has videos of some live presentations that reveal he's also a talented performer. Although debunking VFX in viral videos is usually a low-stakes thing, a few years ago he helped bring down the Cicret Bracelet scam with his debunk videos (Cicret Bracelet DEBUNK and Cicret Bracelet UPDATE). Love with your heart, use your head for everything else.

De politie is op zoek naar twee jongens op een fatbike. Zij pleegden vanmorgen een overval op een juwelier in Dordrecht in het winkelcentrum Crabbehof. Er wordt in de omgeving door agenten gezocht naar de overvallers.
Supporters keken er al een lange tijd naar uit en vandaag was het zover: Het Feyenoord Festival. Rond de Kuip werden de poorten geopend voor duizenden Feyenoord-fans, die de gevoelsmatige start van het nieuwe seizoen beleefden. Rijnmond was erbij!
Ja wacht even hoor. Hugo Borst schrijft een bikkelharde column waarin hij insinueert dat Go Ahead Eagles-fans medeverantwoordelijk zijn voor de dood van scheidsrechter Rob Dieperink. Daar heeft Go Ahead Eagles effe geen zin in, dus die sturen een briefje naar Hugo, die dat dan weer heel ongepast vindt. En pas dán gaat Hugo onderzoek doen of er daadwerkelijk iets naar Dieperink is geroepen (kennelijk, door 1 dronken idioot) en daarna zegt-ie tussen het jengelen over 'uberpestkop Trump' door ook nog dat Dieperink tóch wel uit het leven was gestapt omdat hij 'grote problemen' had, ondanks dat de familie van Dieperink nadrukkelijk heeft gevraagd om privacy. Wat een slecht verhaal man.
