  • Whole body gestational donation (‘Fetal containers’: Bioethicist proposes using brain dead women as surrogates)

    Theoretical Medicine and Bioethics ^ | November 18, 2022 | Anna Smajdo
    Abstract Whole body gestational donation offers an alternative means of gestation for prospective parents who wish to have children but cannot, or prefer not to, gestate. It seems plausible that some people would be prepared to consider donating their whole bodies for gestational purposes just as some people donate parts of their bodies for organ donation. We already know that pregnancies can be successfully carried to term in brain-dead women. There is no obvious medical reason why initiating such pregnancies would not be possible. In this paper, I explore the ethics of whole-body gestational donation. I consider a number of...
  • Americans Addicted to Processed Foods That Could Cause Cancer: New Studies

    New York Post ^ | 1/31 | Brooke Kato
    New research from the Imperial College’s School of Public Health shows that “ultra-processed foods” are linked to an increased risk of developing cancer. The London researchers classified ultra-processed foods as products like carbonated drinks, cereals, mass-produced and packaged bread and pre-packaged meals. The study authors noted that such foods are typically not ingredients used in household cooking but instead are made up of “derived ingredients,” such as high fructose corn syrup or modified starch. They discovered that those who consumed convenience food items were potentially at a higher risk of developing life-threatening cancers after studying 200,000 middle-aged participants over the...

    Four worlds 133 light-years away orbiting a young star. (Jason Wang/Northwestern University) ********************************************************* A new video shared on YouTube is one of the most amazing things we've ever seen in planetary science. The video shows four dots of light moving in partial concentric circles around a black disk at their center. What you're actually looking at is a planetary system. The four dots are exoplanets, with the black disk obscuring their star, 133.3 light-years away from Earth. The partial circles are their orbital motions, a time-lapse compiled from 12 years of observations. The star is HR8799, and in 2008 its...
  • Astronomy Picture of the Day - A Triple View of Comet ZTF

    Explanation: Comet ZTF has a distinctive shape. The now bright comet visiting the inner Solar System has been showing not only a common dust tail, ion tail, and green gas coma, but also an uncommonly distinctive antitail. The antitail does not actually lead the comet -- it is just that the head of the comet is seen superposed on part of the fanned-out and trailing dust tail. The giant dirty snowball that is Comet C/2022 E3 (ZTF) has now passed its closest to the Sun and tomorrow will pass its closest to the Earth. The main panel of the featured...

    Scott Adams is the creator of the famous cartoon strip, Dilbert. It is a strip whose brilliance derives from close observation and understanding of human behavior. Some time ago, Scott turned those skills to commenting insightfully and with notable intellectual humility on the politics and culture of our country. Like many other commentators, he fervently encouraged people to take the Covid “vaccine” and sympathized with measures to pressure people into doing so. Recently, however, he posted a video on the topic that has been circulating on social media. It was a mea culpa in which he declared, “The unvaccinated were...

    Omicron, which emerged in late 2021, has since splintered into hundreds of subvariants — amounting to what's been described as a "variant soup" — and will likely keep splintering into more. "The virus has still got the capacity to evolve and it will evolve … there's no evolutionary dead-end," Professor Holmes said. "We'll definitely see more immune escape variants … but when, where and what they'll be is very hard to say." Splintering virus reflects 'immunologically complex' population While Omicron continues to dominate globally, the current spread of SARS-CoV-2 looks different depending on where you are. "We're seeing this complicated...

    Explanation: Globular clusters once ruled the Milky Way. Back in the old days, back when our Galaxy first formed, perhaps thousands of globular clusters roamed our Galaxy. Today, there are less than 200 left. Over the eons, many globular clusters were destroyed by repeated fateful encounters with each other or the Galactic center. Surviving relics are older than any Earth fossil, older than any other structures in our Galaxy, and limit the universe itself in raw age. There are few, if any, young globular clusters left in our Milky Way Galaxy because conditions are not ripe for more to form....

    Distant Galaxy The image of the most distant galaxy, GHZ2/GLASS-z12. (NASA/ESA/CSA/T. Treu, UCLA/NAOJ/T. Bakx, Nagoya U) A galaxy whose light has traveled nearly 13.5 billion years to reach us has just been confirmed as the earliest galaxy found to date. By studying the oxygen content of the galaxy with the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have precisely dated it to just 367 million years after the Big Bang, a time when the first lights in the Universe were still switching on and starting to propagate freely through space. The result confirms observations made by JWST, and offers new information...

On November 1, 2023, Lucy will get a close-up view of a small main-belt asteroid to conduct an engineering test of the spacecraft’s innovative asteroid-tracking navigation system. The Lucy mission is already breaking records by planning to visit nine asteroids during its 12-year tour of the Jupiter Trojan asteroids, which orbit the Sun at the same distance as Jupiter. Originally, Lucy was not scheduled to get a close-up view of any asteroids until 2025, when it will...
