    If it was me, I'd be pouring a weak concrete mix into the whole lot, burying it under a huge mountain of more concrete, and surrounding it in stone blocks bearing carved warning messages.

    In five to ten thousand years time, some bright spark academic will decide that there is treasure down there and dig it all up.

    Rapid blood test detects cancerous mutations in tumor DNA

    An experimental test successfully detected cancerous mutations in tumor cells by analyzing their DNA that is free-floating in blood, employing a strip test that displays results within 10 minutes.

    In a paper published April 12 in Analytica Chimica Acta, the researchers said their liquid biopsy test is less invasive than standard tissue sampling and could be expanded to detect other cancerous genes.

    Like many healthy cells, cells from cancerous tumors can release fragments of their DNA into the bloodstream when they die. The genetic code of these cells contains mutations that promote cancerous growth, and the blood-borne DNA fragments — called circulating tumor DNA — have become a popular research subject for new cancer diagnosis, treatment and prognosis.

    Tissue biopsy, the removal and testing of a tissue sample for the presence of tumors or other diseases, is the "gold standard" for cancer diagnosis, according to a 2016 review paper in Oncotarget, although it has some limitations that include "unsatisfactory" detection of early-stage tumors or residual lesions.

    The review said that drawing and analyzing blood, the most common form of liquid biopsy, stand to be a promising alternative because of the highly sensitive and specific results of screening for circulating tumor DNA, although the technique still needs further testing for regular clinical use.

    Ikea-Like Pasta Is The Earth-Friendly Food Of The Future


    WHAT’S NEW — This is not the first time this team of researchers has attempted to design a more streamlined and flatter pasta. But they write in the new study that their previous approach had fallen short on demonstrating exactly how to reliably recreate a morphing pasta noodle. In this newest rendition, they were looking to set this record straight.

    “Surface grooves [were] introduced [in our previous work] for morphing flour-based food, since this works with a single material and simple manufacturing method,” write the authors. “However, the previous study did not explain the underlining morphing mechanism and relied heavily on experimental trial and error for the morphing design.”

    [​IMG]


    In other words, while the team determined in their previous study that stamping grooves on flat pasta could coax it into taking on 3D shape in the water, they didn’t yet know exactly why this was happening — at least in terms of a master equation to describe the action.

    Using a mix of physical experiments (on both hydrogel “pasta” and the real deal) and simulations, the team was now able to reliably recreate this morphology to develop and predict the formation of different pasta shapes.

    Wish I had flown on Concorde. I saw her fly a few times.

    Concorde's supersonic engine was actually developed for the BAC TSR-2, one of the most beautiful and advanced aircraft ever developed, that never went into full scale production.

    [​IMG]

    The British Aircraft Corporation TSR-2 (Tactical Strike and Reconnaissance, Mach 2) was developed for the RAF in the late 1950s, and was designed to penetrate a well-defended forward battle area at extremely low altitudes - as low as sea-level - at mach speeds using the most advanced ground-hugging radar and mapping systems ever designed, and deliver a special weapon. It was decades ahead of it's time, but was cancelled after production had begun due to politics.

    The British government had forced the established aviation companies into amalgamation to work on this one design, and the subsequent cancellation of the program damaged Britain's military aviation industry.

    Here's a very good documentary on the TSR-2 program, with interviews of Roland Beamont who was the test pilot, and other leading figures at the time.

    High-speed rail lines have already been implemented around the world with massive success; could this be Canada's next great infrastructure project?

    As Canada's highways become increasingly congested, travelling by train has become more enticing than ever. A Canadian company called HyperCan has put forward a proposal that could turn the 5 and a half hour trip between Montreal and Toronto into a 39-minute journey.

    I met my first Australian sea lion 57 years ago. Today I fear for this delightful animal
    - Valerie Taylor

    [​IMG]

    Eared sea lions, or, as most Australians call them, seals, must be about the sweetest, and most loveable of all sea creatures.

    Man is their great enemy. Another is that incredible predator the great white shark, or white pointer, but whereas the white shark normally attacks only sick, old, or very slow sea lions, man in his usual fashion is generally not so discriminating.

    I met my first Australian sea lion on Dangerous Reef, out front Port Lincoln, South Australia. It was also on Dangerous Reef that I saw them butchered, probably for shark burley (bait). One minute they were watching with wide-eyed curiosity and the next they were being shot falling next to their startled pups. Man had once again triumphed ever the innocent and helpless. That happened about 57 years ago and has no doubt been happening ever since.

    On 15 January 1975 the Australian sea lions on Dangerous Reef numbered about 60 or 80 animals. Six years before at the same time there had been 200 or more. I know because I counted them myself.

    Using Ron’s footage and TV interviews I had successfully had the killing of all seal lions in Australian waters banned. I know many eared seals fall prey to different natural causes but the introduction of man the hunter, the polluter, the uncaring has been the main cause of their decline.

    Unless the government proclaims larger marine sanctuary areas around the remaining sea lion colonies I fear this delightful animal will become like the Tasmanian Tiger, only an image in a picture book.

    Sharks use Earth's magnetic fields to guide them like a map

    Sea turtles are known for relying on magnetic signatures to find their way across thousands of miles to the very beaches where they hatched. Now, researchers reporting in the journal Current Biology on May 6 have some of the first solid evidence that sharks also rely on magnetic fields for their long-distance forays across the sea.

    "It had been unresolved how sharks managed to successfully navigate during migration to targeted locations," said Save Our Seas Foundation project leader Bryan Keller, also of Florida State University Coastal and Marine Laboratory. "This research supports the theory that they use the earth's magnetic field to help them find their way; it's nature's GPS."

    How we discovered the oldest human burial in Africa – and what it tells us about our ancestors

    [​IMG]

    How did human uniqueness first evolve among our ancestors, setting us apart from other animals? That is a question many archaeologists are grappling with by investigating early records of art, language, food preparation, ornaments and symbols. How our ancestors treated and mourned the dead can also offer crucial clues, helping to reveal when we first developed the abstract thinking needed to fully grasp the concept of death.

    Now we have discovered a 78,000-year-old human burial at a cave in the tropical coast of eastern Africa, which provides tantalising evidence about our ancestors’ treatment of the dead. Our new study, published in Nature, describes the burial of a 2½ to 3-year-old child, nicknamed “Mtoto” (Swahili for “child”), at the Panga ya Saidi archaeological site in Kenya. It is the earliest known Homo sapiens burial in Africa.

    The excavations began in 2010. So far, they have revealed a record of human occupation from 78,000 to 500 years ago, covering the Middle Stone Age and Later Stone Age periods of African archaeology. Mtoto’s burial lay towards the base of the excavation site and was first recognised because it contained sediment of a different colour from the surroundings.

    Good research begins long before papers get written

    Nature.com EDITORIAL

    Publishers are redoubling their commitment to transparency and reproducibility — but they can’t bring about change alone.

    In 2013, Nature began asking the authors of life-sciences papers to provide extra information in a bid to tackle the pressing problem of poor reproducibility in research. According to one survey of Nature authors conducted in 2016–17, 86% of respondents considered poor reproducibility to be a growing challenge in the life sciences.

    Researchers in these fields are now asked to use a structured reporting summary for their manuscript submissions. Among other things, the checklist requires authors to state whether their experimental findings have been replicated; how they determined an appropriate sample size; whether they randomized samples; and whether data have been assessed by researchers who did not know which group they were assessing.

    Such a checklist, which is provided to peer reviewers and published with each life-sciences paper, has helped to improve transparency in the reporting of research1,2. But editors from many journals and researchers recognize that there is still work to be done.

    If we want to save the planet, the future of food is insects

    My first attempts at feeding insects to friends and family did not go down well. “What the hell is wrong with you?” asked my wife when I revealed that the tomato and oregano-flavoured cracker bites we had been munching with our G&Ts were made from crickets. “Hang on, I’m vegetarian!” cried our friend – which prompted a slightly testy discussion on whether insects count as meat, how many thousand arthropods equate to one mammal and considering almost all industrial agriculture involves the mass slaughter of insects, what’s the difference?

    I'm thinking this will be an acquired taste.

    Hi-tech bridge failure...

    A tourist was left clinging for life after a glass-panelled sky bridge suspended 91 metres in the air in China was wrecked by 145km/h winds.

    The walkway, located in the Piyan Mountain in the city of Longjing, reportedly saw its glass panels shattered by the extreme weather conditions.

    Scientists Discover New Auroral Phenomenon Hidden in 19-Year-Old Video Footage

    Not all auroras slither through the sky like snakes. Some – called diffuse aurora – are more like an even glow dispersed throughout the sky.

    Scientists know a fair bit about these diffuse auroras, but an old video from 2002 revealing what seems to be an undocumented auroral phenomenon shows we definitely don't know everything.




    "We found these events in a movie taken the night of March 15, 2002 in Churchill, [Manitoba], Canada," the researchers write in a summary of their research.

    "They appear as a section of diffuse aurora that rapidly brightens, then disappears and also erases the background aurora. Then, over the course of several tens of seconds, the diffuse aurora recovers to its original brightness."
