    An Indonesian family have been reunited with their drowned son after his body was carried to the surface of the Mahakam River by a crocodile. In footage shared to social media, the crocodile can be seen carrying the body of the 4-year old boy to a boat of rescuers, who retrieved him from the water and brought him back to his family. The boy, who was later identified as Muhammad Ziyad Wijaya, had gone missing two days before near the Jawa Estuary. Members of the East Kalimantan Basarnas Search and Rescue Agency had been searching for the boy. "Around seven...
  • Dietary nitrate—found in beetroot juice—significantly increases muscle force during exercise

    01/25/2023 3:43:46 PM PST · by ConservativeMind · 28 replies
    A new study has found that consuming dietary nitrate—the active molecule in beetroot juice—significantly increased muscle force while exercising. While it is known that dietary nitrate enhances exercise, both boosting endurance and enhancing high-intensity exercise, researchers still have much to learn about why this effect occurs, and how our bodies convert dietary nitrate that we ingest into the nitric oxide that can be used by our cells. To help close this gap traced the distribution of ingested nitrate in the saliva, blood, muscle and urine of ten healthy volunteers, who were then asked to perform maximal leg exercise. The team...

    Artist conception of the James Webb Space Telescope. Credit: NASA GSFC/CIL/Adriana Manrique Gutierrez On Sunday, January 15, 2023, the James Webb Space Telescope’s Near Infrared Imager and Slitless Spectrograph (NIRISS) experienced a communications delay within the instrument, causing its flight software to time out. The instrument is currently unavailable for science observations while NASA and the Canadian Space Agency (CSA) work together to determine and correct the root cause of the delay. There is no indication of any danger to the hardware, and the observatory and other instruments are all in good health. The affected science observations will be...

    One of the bigger questions surrounding NASA’s interest in sending a crewed mission to Mars surrounds the best way to get there, and it appears the agency might have found its answer. NASA announced today that it will be developing a nuclear thermal rocket engine in collaboration with the Defense Advanced Research Projects Agency (DARPA). The collaboration is called DRACO, or Demonstration Rocket for Agile Cislunar Operations, and it’s expected to reduce the travel time it takes to get astronauts to Mars—and potentially more distant targets in deep space. According to a press release, NASA will lead technical development of...

    Asteroid 2023 BU imaged by the Virtual Telescope as it approached Earth in January 2023. (Image credit: Virtual Telescope Project) Wednesday, January 25, 2023: A newly discovered asteroid that will pass very close to Earth on Friday has been photographed by an Italian astronomer as it makes its approach. The space rock, called 2023 BU, is only about 13 to 30 feet (4 to 9 meters) wide, and was discovered last Saturday (Jan. 21) by prolific Crimea-based astronomer and telescope builder Gennadiy Borisov (the same man who discovered the first interstellar comet, which now bears his name, Borisov, in 2018)...
  • Scientists have started steering lightning with lasers – here’s how

    The Conversation ^ | January 20, 2023
    This latest experiment was performed near a telecommunications tower on the Säntis mountain in Switzerland that is frequently struck by lightning - roughly 100 times a year, although the tower itself is protected by a lightning rod. The results from the study found the lightning flowed almost in a straight line near the laser pulses, but the lightning strikes were more randomly distributed when the laser was off. While this study is not the first attempt to direct lightning paths it is the first to show it can be done. The scientists have attributed this to the high power laser...
  • Earth’s inner core paused, then reversed its spin. This is fine

    Seattle Times ^ | January 23, 2023 | Robert George Andrews
    Imagine Earth’s inner core — the dense center of our planet — as a heavy, metal ballerina. This iron-rich dancer is capable of pirouetting at ever-changing speeds. That core may be on the cusp of a big shift. Seismologists reported Monday in the journal Nature Geoscience that after brief but peculiar pauses, the inner core changes how it spins — relative to the motion of Earth’s surface — perhaps once every few decades. And, right now, one such reversal may be underway. This may sound like a setup for a world-wrecking, blockbuster movie. But fret not: Precisely nothing apocalyptic will...

    Large Antarctica meteorite The large meteorite that's been recovered. (Maria Valdes) ******************************************************************* Antarctica has a lot going for it when it comes to meteorite hunting. The dark rocks stand out against the icy landscape. Its dry climate keeps weathering to a minimum. And even when meteorites sink into the ice they are often returned to the surface by the churning of the glaciers. In spite of these ideal conditions, finding sizeable chunks of space rock is rare. A group of researchers have just returned from the ice-covered continent with five new meteorites that include an unusually large specimen. The big...
  • A New Frontier: NASA’s Webb Space Telescope Confirms Existence of Earth-Sized Rocky Exoplanet!

    Exoplanet LHS 475 b and Its Star This illustration reflects that exoplanet LHS 475 b is rocky and almost precisely the same size as Earth based on new evidence from NASA’s James Webb Space Telescope. The planet is only a few hundred degrees warmer than our home planet. The planet whips around its star in just two days, far faster than any planet in the solar system, but its red dwarf star is less than half the temperature of the Sun. Researchers will follow up this summer with another observation with Webb, which they hope will allow them to definitively...

    Imagine if a robotic probe arrived in our Solar System, sent by an ETC. They detected us and sent their probe to introduce themselves and learn more about us. Then imagine our sensors detect another incoming probe from the same place as the previous one. Imagine our surprise when we retrieve it, and begin to study it, only to find that it's not as advanced as the previous one and contains older information and messages than the first one. That's exactly what might happen, according to Graeme Smith. Smith is a professor and an astronomer at the Department of Astronomy...

    A Colorado astrophysicist has claimed her field is steeped in white supremacy and sexism because 'hypermasculine' and 'violent' language is used to describe stars. Natalie Gosnell, an assistant professor at Colorado College, takes an unconventional approach to physics by comparing stars with humans to turn science into an art. In an interview with the college newspaper she claimed she has struggled to overcome a division between art and science that is rooted in 'systemic racism

    Explanation: The hydrogen in your body, present in every molecule of water, came from the Big Bang. There are no other appreciable sources of hydrogen in the universe. The carbon in your body was made by nuclear fusion in the interior of stars, as was the oxygen. Much of the iron in your body was made during supernovas of stars that occurred long ago and far away. The gold in your jewelry was likely made from neutron stars during collisions that may have been visible as short-duration gamma-ray bursts or gravitational wave events. Elements like phosphorus and copper are present...

    The ancient Greek historian Strabo referred to the presence of an important shrine located on the west coast of the Peloponnese some 2,000 years ago. Remains of such an Archaic temple have now been uncovered at the Kleidi site near Samikon, which presumably once formed part of the sanctuary of Poseidon.Researchers of the Austrian Archaeological Institute in collaboration with colleagues from Johannes Gutenberg University Mainz (JGU), Kiel University, and the Ephorate of Antiquities of Elis unearthed the remains of an early temple-like structure that was located within the Poseidon sanctuary site and was quite possibly dedicated to the deity himself....

    CNN medical analyst and Washington Post columnist Dr. Leana Wen admitted in a column, Friday, that the medical community is “overcounting” the amount of “COVID deaths and hospitalizations.” Wen, who writes an occasional Washington Post column providing her observations on the pandemic, masking and other COVID-related subjects, cited sources claiming that most “patients diagnosed with COVID are actually in the hospital for some other illness.” The article is titled, “We are overcounting COVID deaths and hospitalizations. That’s a problem." Wen’s observations prompted readers on Twitter to complain, stating that it’s “two and a half years late.” Wen began her column...

    Former Acting FDA Commissioner, Dr. Brett Giroir, told Newsmax on Saturday that, while he can't prove anything, it is not a good look when Dr. Scott Gottlieb, a former FDA commissioner who sits on Pfizer's board, calls for the censorship of natural immunity. In late August 2021, Giroir, who served as former President Donald Trump's COVID-19 testing czar, tweeted, "It's now clear #COVID19 natural immunity is superior to #vaccine immunity, by ALOT." He then urged Centers for Disease Control and Prevention Director Dr. Rochelle Walensky and President Joe Biden to "follow the science," before adding, "If no previous infection? Get...

    U.S. — Medical experts are absolutely stumped as to what could be causing the recent uptick in healthy, young people everywhere that are suddenly collapsing with heart failure. Despite their uncertainty, experts do feel confident that we can rule out that one thing as the culprit. "It's too early to say what could be causing this, but it's never too early to say what isn't causing this," said local expert, Dr. Scott Rufflinger. "This could be caused by anything. But the one thing we know for certain is that it's definitely not what we're all thinking that's behind this —...

    The rate of ground-breaking scientific discoveries and technological innovation is slowing down despite an ever-growing amount of knowledge, according to an analysis released Wednesday of millions of research papers and patents. While previous research has shown downturns in individual disciplines, the study is the first that "emphatically, convincingly documents this decline of disruptiveness across all major fields of science and technology," lead author Michael Park told AFP. Park, a doctoral student at the University of Minnesota's Carlson School of Management, called disruptive discoveries those that "break away from existing ideas" and "push the whole scientific field into new territory."
