Dear olivier hartmanshenn,

Here is your customized Science X Newsletter for week 12:

	Ancient giant dolphin discovered in the Amazon Paleontologists from the University of Zurich have announced the discovery of a new species of freshwater dolphin in the Peruvian Amazon region. Surprisingly, its closest living relatives can be found in the river dolphins of South Asia.
	Largest-ever map of universe's active supermassive black holes released Astronomers have charted the largest-ever volume of the universe with a new map of active supermassive black holes living at the centers of galaxies. Called quasars, the gas-gobbling black holes are, ironically, some of the universe's brightest objects.
	Neolithic boats excavated in the Mediterranean reveal advanced nautical technology More than 7,000 years ago, people navigated the Mediterranean Sea using technologically sophisticated boats, according to a study published March 20, 2024, in the open-access journal PLOS ONE by Juan F. Gibaja of the Spanish National Research Council, Barcelona and colleagues.
	New research shows unintended harms of organic farming Organic farming is often touted as a more sustainable solution for food production, leveraging natural forms of pest control to promote eco-friendly cultivation.
	Self-heating concrete is one step closer to putting snow shovels and salt out of business There's a patch of concrete on Drexel University's campus that could portend a frost-free future for sidewalks and highways in the Northeast.
	Signs of life detectable in single ice grain emitted from extraterrestrial moons, experimental setup shows The ice-encrusted oceans of some of the moons orbiting Saturn and Jupiter are leading candidates in the search for extraterrestrial life. A new lab-based study led by the University of Washington in Seattle and the Freie Universität Berlin shows that individual ice grains ejected from these planetary bodies may contain enough material for instruments headed there in the fall to detect signs of life, if such life exists.
	Astrophysicist explains science behind once-in-a-lifetime nova outburst that will light up the sky this year The total solar eclipse isn't the only reason to keep your eyes to the sky this year. For the first time in 80 years, a star system 3,000 light years away will be visible to the naked eye thanks to a once-in-a-lifetime nova outburst.
	Bilingual child cannot 'turn off' their language knowledge, says researcher Worldwide, there are more children who grow up learning multiple languages than children learning only one. And yet monolingualism is often taken as a starting point, for example in school. Research by linguist Elly Koutamanis shows that the two languages of a bilingual child are always active in their brain. "A child can benefit from this bilingual knowledge at school." Koutamanis will receive her Ph.D. on language interaction in bilingual children on 22 March.
	No 'human era' in Earth's geological history, scientists say A top panel of geologists has decided not to grant the 'human age' its own distinct place in Earth's geological timeline after disagreeing over when exactly our era might have begun.
	Study reports enormous ice loss from Greenland glacier Ground-based measuring devices and aircraft radar operated in the far northeast of Greenland show how much ice the 79° N-Glacier is losing. According to measurements conducted by the Alfred Wegener Institute, the thickness of the glacier has decreased by more than 160 meters since 1998. Warm ocean water flowing under the glacier tongue is melting the ice from below.
	As Voyager 1's mission draws to a close, one planetary scientist reflects on its legacy For nearly 50 years, NASA's Voyager 1 mission has competed for the title of deep space's little engine that could. Launched in 1977 along with its twin, Voyager 2, the spacecraft is now soaring more than 15 billion miles from Earth.
	Shakespeare's sister: Digital archives reveal hidden insights into world-famous playwright's unknown sibling By analyzing digital copies of an incredibly rare and obscure 17th-century Italian religious text, a University of Bristol academic has revealed that a long-lost document previously thought to have been written by William Shakespeare's father belongs, in fact, to his relatively unknown sister Joan.
	CERN measures coupled resonance structure that may cause particle loss in accelerators for the first time Whether in listening to music or pushing a swing in the playground, we are all familiar with resonances and how they amplify an effect—a sound or a movement, for example. However, in high-intensity circular particle accelerators, resonances can be an inconvenience, causing particles to fly off their course and resulting in beam loss. Predicting how resonances and non-linear phenomena affect particle beams requires some very complex dynamics to be disentangled.
	Top computer scientists say the future of artificial intelligence is similar to that of Star Trek Leading computer scientists from around the world have shared their vision for the future of artificial intelligence—and it resembles the capabilities of Star Trek character "The Borg."
	Hypoxia is widespread and increasing in the ocean off the Pacific Northwest coast, study shows Low oxygen conditions that pose a significant threat to marine life are widespread and increasing in coastal Pacific Northwest ocean waters as the climate warms, a new study shows.
	NASA study: Asteroid's orbit, shape changed after DART impact After NASA's historic Double Asteroid Redirection Test, a JPL-led study has shown that the shape of asteroid Dimorphos has changed and its orbit has shrunk.
	Astrophysicist's research could provide a hint in the search for dark matter Dark matter is one of science's greatest mysteries. It doesn't absorb, reflect or emit light, so we can't see it. But its presence is implied by the gravitational effects it appears to have on galaxies.
	Root cause of Alzheimer's may be fat buildup in brain cells, research suggests A team of neurologists, stem cell specialists and molecular biologists affiliated with several institutions in the U.S. and led by a group at Stanford University School of Medicine has found evidence that the root cause of Alzheimer's disease may be fat buildup in brain cells. The study is published in the journal Nature.
