Science X Newsletter Week 37

Dear Reader ,

Here is your customized Science X Newsletter for week 37:

	Bone, not adrenaline, drives fight or flight response When faced with a predator or sudden danger, the heart rate goes up, breathing becomes more rapid, and fuel in the form of glucose is pumped throughout the body to prepare an animal to fight or flee.
	Scientists detect the ringing of a newborn black hole for the first time If Albert Einstein's theory of general relativity holds true, then a black hole, born from the cosmically quaking collisions of two massive black holes, should itself "ring" in the aftermath, producing gravitational waves much like a struck bell reverbates sound waves. Einstein predicted that the particular pitch and decay of these gravitational waves should be a direct signature of the newly formed black hole's mass and spin.
	Black hole at the center of our galaxy appears to be getting hungrier The enormous black hole at the center of our galaxy is having an unusually large meal of interstellar gas and dust, and researchers don't yet understand why.
	Are black holes made of dark energy? Two University of Hawaii at Manoa researchers have identified and corrected a subtle error that was made when applying Einstein's equations to model the growth of the universe.
	Towering balloon-like structures discovered near center of the Milky Way An international team of astronomers, including Northwestern University's Farhad Yusef-Zadeh, has discovered one of the largest structures ever observed in the Milky Way. A newly spotted pair of radio-emitting bubbles reach hundreds of light-years tall, dwarfing all other structures in the central region of the galaxy.
	Skin-crawling discovery: 'body farm' scientists find corpses move An Australian scientist has proved that human bodies move around significantly for more than a year after death, in findings that could have implications for detectives and pathologists around the world.
	Feds finalize plan to open Alaska's Arctic National Wildlife Refuge to oil drilling The Trump administration announced Thursday its final plan to open Alaska's Arctic National Wildlife Refuge to oil drilling, giving the petroleum industry access to the pristine wildland for the first time.
	Study identifies first potential biomarker for a debilitating fainting condition New research from the University of Toledo College of Medicine and Life Sciences strongly suggests postural orthostatic tachycardia syndrome, or POTS, is an autoimmune disorder, and may help pave the way for a simple blood test that could help physicians diagnose the condition.
	Veterans with PTSD, anxiety turn to beekeeping for relief Gently lifting a wooden frame containing dozens of Italian honeybees, Vince Ylitalo seemed transfixed as he and several other veterans inspected the buzzing insects.
	Researchers produce synthetic Hall Effect to achieve one-way radio transmission Researchers at the University of Illinois at Urbana-Champaign have replicated one of the most well-known electromagnetic effects in physics, the Hall Effect, using radio waves (photons) instead of electric current (electrons). Their technique could be used to create advanced communication systems that boost signal transmission in one direction while simultaneously absorbing signals going in the opposite direction.
	Fermilab achieves world-record field strength for accelerator magnet To build the next generation of powerful proton accelerators, scientists need the strongest magnets possible to steer particles close to the speed of light around a ring. For a given ring size, the higher the beam's energy, the stronger the accelerator's magnets need to be to keep the beam on course.
	High-fat, high-carbohydrate diets affect your brain, not just your physical appearance Much research has pointed to how an unhealthy diet correlates to obesity, but has not explored how diet can bring about neurological changes in the brain. A recent Yale study has discovered that high-fat diets contribute to irregularities in the hypothalamus region of the brain, which regulates body weight homeostasis and metabolism.
	First water detected on potentially 'habitable' planet K2-18b, which is eight times the mass of Earth, is now the only planet orbiting a star outside the Solar System, or 'exoplanet', known to have both water and temperatures that could support life.
	The enigma of bronze age tin The origin of the tin used in the Bronze Age has long been one of the greatest enigmas in archaeological research. Now researchers from Heidelberg University and the Curt Engelhorn Centre for Archaeometry in Mannheim have solved part of the puzzle. Using methods of the natural sciences, they examined the tin from the second millennium BCE found at archaeological sites in Israel, Turkey, and Greece. They were able to prove that this tin in the form of ingots does not come from Central Asia, as previously assumed, but from tin deposits in Europe. The findings are proof that even in the Bronze Age, complex and far-reaching trade routes must have existed between Europe and the Eastern Mediterranean. Highly appreciated raw materials like tin as well as amber, glass, and copper were the driving forces of this early international trade network.
	Introducing quantum convolutional neural networks Machine learning techniques have so far proved to be very promising for the analysis of data in several fields, with many potential applications. However, researchers have found that applying these methods to quantum physics problems is far more challenging due to the exponential complexity of many-body systems.
	Study finds the universe might be 2 billion years younger The universe is looking younger every day, it seems.
	Ash tree species likely will survive emerald ash borer beetles, but just barely "Lingering ash." That's what the U.S. Forest Service calls the relatively few green and white ash trees that survive the emerald ash borer onslaught. Those trees do not survive by accident, and that may save the species, according to Penn State researchers, who conducted a six-year study of ash decline and mortality.
	New blood test for prostate cancer is highly-accurate and avoids invasive biopsies A new and simple blood test has been found to efficiently and accurately detect the presence of aggressive prostate cancer, according to research by Queen Mary University of London.
	Rocks at asteroid impact site record first day of dinosaur extinction When the asteroid that wiped out the dinosaurs slammed into the planet, the impact set wildfires, triggered tsunamis and blasted so much sulfur into the atmosphere that it blocked the sun, which caused the global cooling that ultimately doomed the dinos.
	Researchers unearth 'new' extinction A team of scientists has concluded that earth experienced a previously underestimated severe mass-extinction event, which occurred about 260 million years ago, raising the total of major mass extinctions in the geologic record to six.
