Science X Newsletter Week 27

Dear Reader ,

Here is your customized Science X Newsletter for week 27:

	Insect apocalypse: German bug watchers sound alarm For almost 30 years they passed as quirky eccentrics, diligently setting up their insect traps in the Rhine countryside to collect tens of millions of bugs and creepy crawlers.
	Dementia tied to hormone-blocking prostate cancer treatment Alzheimer's disease may be a risk for older prostate cancer patients given hormone-blocking treatment, a large, U.S. government-funded analysis found.
	E-scooters: a transport 'tsunami' flooding cities worldwide They appeared in June last year as Paris was waking up from its annual all-night Festival of Music: hundreds of green-and-black electric scooters dotting the pavements of the capital.
	Scientists combine light and matter to make particles with new behaviors Every type of atom in the universe has a unique fingerprint: It only absorbs or emits light at the particular energies that match the allowed orbits of its electrons. That fingerprint enables scientists to identify an atom wherever it is found. A hydrogen atom in outer space absorbs light at the same energies as one on Earth.
	Artificial gravity breaks free from science fiction Artificial gravity has long been the stuff of science fiction. Picture the wheel-shaped ships from films like 2001: A Space Odyssey and The Martian, imaginary craft that generate their own gravity by spinning around in space.
	Best way to fight climate change? Plant a trillion trees The most effective way to fight global warming is to plant lots of trees, a study says. A trillion of them, maybe more.
	Study finds electronic cigarettes damage brain stem cells A research team at the University of California, Riverside, has found that electronic cigarettes, often targeted to youth and pregnant women, produce a stress response in neural stem cells, which are critical cells in the brain.
	Tiny granules can help bring clean and abundant fusion power to Earth Beryllium, a hard, silvery metal long used in X-ray machines and spacecraft, is finding a new role in the quest to bring the power that drives the sun and stars to Earth. Beryllium is one of the two main materials used for the wall in ITER, a multinational fusion facility under construction in France to demonstrate the practicality of fusion power. Now, physicists from the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) and General Atomics have concluded that injecting tiny beryllium pellets into ITER could help stabilize the plasma that fuels fusion reactions.
	First observation of native ferroelectric metal In a paper released today in Science Advances, Australian researchers describe the first observation of a native ferroelectric metal: a native metal with bistable and electrically switchable spontaneous polarization states—the hallmark of ferroelectricity. The study found coexistence of native metallicity and ferroelectricity in bulk crystalline tungsten ditelluride (WTe2) at room temperature. A van-der-Waals material that is both metallic and ferroelectric in its bulk crystalline form at room temperature has potential for nano-electronics applications.
	New model suggests lost continents for early Earth A new radioactivity model of Earth's ancient rocks calls into question current models for the formation of Earth's continental crust, suggesting continents may have risen out of the sea much earlier than previously thought but were destroyed, leaving little trace.
	Bonobo diet of aquatic greens may hold clues to human evolution Observations of bonobos in the Congo basin foraging in swamps for aquatic herbs rich in iodine, a critical nutrient for brain development and higher cognitive abilities, may explain how the nutritional needs of prehistoric humans in the region were met. This is the first report of iodine consumption by a nonhuman primate and it is published in the open access journal BMC Zoology.
	With little training, machine-learning algorithms can uncover hidden scientific knowledge Sure, computers can be used to play grandmaster-level chess (chess_computer), but can they make scientific discoveries? Researchers at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have shown that an algorithm with no training in materials science can scan the text of millions of papers and uncover new scientific knowledge.
	A counterintuitive case in which like charges attract When it comes to electric charge, there is one overriding theme: opposites attract, and like charges repel. But in a new study, physicists have made the surprising discovery that two spherical like-charged metal nanoparticles with unequal charges can attract one another in a dilute electrolyte solution. The reason, in short, is that the more strongly charged nanoparticle polarizes the metal core of the weakly charged nanoparticle, which alters the interaction between the nanoparticles.
	Quorn protein builds muscle better than milk protein A study from the University of Exeter has found that mycoprotein, the protein-rich food source that is unique to Quorn products, stimulates post-exercise muscle building to a greater extent than milk protein.
	Physicist finds loose thread of string theory puzzle A University of Colorado Boulder physicist is one step closer to solving a string theory puzzle 20 years in the making.
	Cholesterol that is too low may boost risk for hemorrhagic stroke Current guidelines recommend lowering cholesterol for heart disease risk reduction. New findings indicate that if cholesterol dips too low, it may boost the risk of hemorrhagic stroke, according to researchers.
	Hubble captures cosmic fireworks in ultraviolet Hubble offers a special view of the double star system Eta Carinae's expanding gases glowing in red, white, and blue. This is the highest resolution image of Eta Carinae taken by the NASA/ESA Hubble Space Telescope.
	Study reveals a short bout of exercise enhances brain function Most people know that regular exercise is good for your health. New research shows it may make you smarter, too.
	Molecular thumb drives: Researchers store digital images in metabolite molecules DNA molecules are well known as carriers of huge amounts of biological information, and there is growing interest in using DNA in engineered data storage devices that can hold vastly more data than our current hard drives. But new research shows that DNA isn't the only game in town when it comes to molecular data storage.
	Portable polarization-sensitive camera could be used in machine vision, autonomous vehicles, security and more When the first full-length movie made with the advanced, three-color process of Technicolor premiered in 1935, The New York Times declared "it produced in the spectator all the excitement of standing upon a peak ... and glimpsing a strange, beautiful and unexpected new world."
