Russia is revisiting its Soviet space heritage for a new series of missions that will take the nation back to the moon. The first of those missions, dubbed Luna 25, is scheduled to launch this October, ending a 45-year drought of Russian moon landings with the nation's first arrival at the south pole, where, like everyone else targeting the moon, Russian scientists want to study water locked below the surface in permanent ice. https://www.space.com/russia-luna-25-returning-to-moon?

"Implantation of human-monkey embryos would be ethically contentious and will need to be discussed by scientists, ethicists and the public before moving forward with such experiments," https://www.livescience.com/human-monkey-chimeric-embryos.html? https://www.cell.com/cell/fulltext/S0092-8674(21)00375-5 https://www.cell.com/cell/fulltext/S0092-8674(21)00305-6

This event was predicted in 1973 but had never been seen in the real world. Scientists predicted the existence of the particle, known as the odderon, in 1973, describing it as a rare, short-lived conjointment of three smaller particles known as gluons. Since then, researchers have suspected that the odderon might appear when protons slammed together at extreme speeds, but the precise conditions that would make it spring into existence remained a mystery. Now, after comparing data from the Large Hadron Collider (LHC), the 17-mile-long (27 kilometers) ring-shaped atom smasher near Geneva that's famous for discovering the Higgs boson, and the Tevatron, a now-defunct 3.9-mile-long (6.3 km) American collider that slammed protons and their antimatter twins (antiprotons) together in Illinois until 2011, researchers report conclusive evidence of the odderon's existence. https://www.livescience.com/ultra-rare-odderon-particle-detected.html? https://www.livescience.com/65119-odderons-quasiparticles-detected.html https://arxiv.org/abs/1903.06992

SpaceX is moving on quickly from its latest fallen Starship prototype. Elon Musk's company rolled out the newest Starship test vehicle, known as SN15 ("Serial No. 15"), its South Texas launch pad last Thursday (April 8), just over a week after its predecessor exploded during a high-altitude flight. That previous vehicle, SN11, performed well during most of its 6.2-mile-high (10 kilometers) flight on March 30 but suffered a serious problem while gearing up for landing. (SpaceX skipped the SN12, SN13 and SN14 iterations, going directly from SN11 to SN15.) https://www.space.com/spacex-starship-sn15-launch-pad?

All of the forces we experience every day can be reduced to just four categories: gravity, electromagnetism, the strong force and the weak force. Now, physicists say they have found possible signs of a fifth fundamental force of nature. https://www.bbc.com/news/56643677 https://www.bbc.com/news/science-environment-56491033

Based on data from the Ingenuity Mars helicopter that arrived late Friday night, NASA has chosen to reschedule the Ingenuity Mars Helicopter’s first experimental flight to no earlier than April 14. During a high-speed spin test of the rotors on Friday, the command sequence controlling the test ended early due to a “watchdog” timer expiration. This occurred as it was trying to transition the flight computer from ‘Pre-Flight’ to ‘Flight’ mode. The helicopter is safe and healthy and communicated its full telemetry set to Earth. https://mars.nasa.gov/technology/helicopter/status/291/mars-helicopter-flight-delayed-to-no-earlier-than-april-14/ https://twitter.com/NASAJPL/status/1380404668069650437

Prince Philip's Death Marks the End of Royal Dynastic Unions. In November 1947, a dynastic union was forged between the royal houses of Greece and Great Britain. It would be one of the last of this kind of royal marriages in history – a type of union that had knitted together the continent for 1,000 years. https://www.royal.uk/condolence?fbclid=IwAR35WY43XM10naViaq_X3HgK-u1gGVCbHNkKi6u5sj8SZuNRHoYUTtInKdo https://theconversation.com/prince-philip-dies-his-marriage-to-the-queen-and-their-part-in-1-000-years-of-european-royal-dynastic-history-155696?fbclid=IwAR2tyeTLaTWxPEh5u0TC-Z-4O9a9R59RwaC1pZWGgrIYKZIb1ki-CQk9-6w

The Mars helicopter Ingenuity has unlocked its two rotor blades as preparations continue for the vehicle's first flight, due to occur no earlier than Sunday (April 11). https://www.space.com/mars-helicopter-ingenuity-unlocks-rotor-blades? https://twitter.com/NASAJPL/status/1380050243316711426

April 05, 2021 This low-resolution view of the floor of Mars’ Jezero Crater and a portion of two wheels of NASA’s Perseverance Mars rover was captured by the color imager aboard the agency’s Ingenuity Mars helicopter. The image was taken on April 3, 2021, while the solar-powered rotorcraft was still beneath the rover after being deployed. A few higher-resolution images are expected to be acquired by this imager during each of Ingenuity’s test flights. https://mars.nasa.gov/resources/25782/ingenuitys-first-color-snap/#.YGtX9yOIvpo.twitter

The interplanetary helicopter was previously set to take off no sooner than April 8, but the little craft will now take flight no earlier than April 11, NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California, announced via Twitter Wednesday (March 31). https://www.space.com/ingenuity-mars-helicopter-flight-delayed-april-11?

LOOKING FORWARD, Freeform Reversible Embedding of Suspended Hydrogels (FRESH) has applications in many aspects of regenerative medicine, from wound repair to organ bioengineering, but it is just one piece of a growing biofabrication field. "Really what we're talking about is the convergence of technologies," says Adam Feinberg, a professor of biomedical engineering (BME) and materials science & engineering at Carnegie Mellon University, Pennsylvania, USA. https://medicalxpress.com/news/2019-08-d-human-heart.html?fbclid=IwAR1Np-TkDvWsULfEeLgsTGUBEr871LoN6vfoxJXhaEt7IXv340if_KnFBv4 https://advances.sciencemag.org/content/1/9/e1500758

If a new theory turns out to be true, the universe may not have started with a bang. In the new formulation, the universe was never a singularity, or an infinitely small and infinitely dense point of matter. In fact, the universe may have no beginning at all. https://www.livescience.com/49958-theory-no-big-bang.html

Like its predecessors, SN11 did not survive its brief flight, exploding during the test, although the foggy conditions in Boca Chica made it difficult to see. https://www.space.com/spacex-starship-sn11-rocket-launch-2nd-attempt?

Scientists have crafted a single-celled synthetic organism that divides and multiplies just like the real thing.
