Science X Newsletter Week 31

Dear Reader ,

Here is your customized Science X Newsletter for week 31:

	New approach could make HVAC heat exchangers five times more efficient Researchers from Tsinghua University and Brown University have discovered a simple way to give a major boost to turbulent heat exchange, a method of heat transport widely used in heating, ventilation and air conditioning (HVAC) systems.
	High levels of estrogen in the womb linked to autism Scientist have identified a link between exposure to high levels of oestrogen sex hormones in the womb and the likelihood of developing autism. The findings are published today in the journal Molecular Psychiatry.
	Blood test is 94% accurate at identifying early Alzheimer's disease Up to two decades before people develop the characteristic memory loss and confusion of Alzheimer's disease, damaging clumps of protein start to build up in their brains. Now, a blood test to detect such early brain changes has moved one step closer to clinical use.
	A 3-D model of the Milky Way Galaxy using data from Cepheids A team of researchers at the University of Warsaw has created the most accurate 3-D model of the Milky Way Galaxy to date. In their paper published in the journal Science, the group explains how they used measurements from a special group of pulsating stars to create the map.
	Ultra-thin layers of rust generate electricity from flowing water There are many ways to generate electricity—batteries, solar panels, wind turbines, and hydroelectric dams, to name a few examples… and now, there's rust.
	Ro5 researchers suggest radioactive readings in 2017 were from a major nuclear release A very large team of researchers from across Europe has found evidence that suggests radioactive ruthenium readings across the continent in 2017 were from an unknown nuclear source. In their paper published in Proceedings of the National Academy of Sciences, the group describes their study of the unusual readings two years ago and what they found.
	Study shows that the Moon is older than previously believed A new study spearheaded by Earth scientists at the University of Cologne's Institute of Geology and Mineralogy has constrained the age of the Moon to approximately 50 million years after the formation of the solar system. After the formation of the solar system, 4.56 billion years ago, the Moon formed approximately 4.51 billion years ago. The new study has thus determined that the Moon is significantly older than previously believed—earlier research had estimated the Moon to have formed approximately 150 million years after solar system's formation. To achieve these results, the scientists analysed the chemical composition of a diverse range of samples collected during the Apollo missions. The study "Early Moon formation inferred from hafnium-tungsten systematics' was published in Nature Geoscience.
	Archaeology student makes an unusual find at a Peruvian dig Caroline Coolidge was stunned.
	TESS satellite uncovers 'first nearby super-Earth' An international team of astronomers led by Cornell's Lisa Kaltenegger has characterized the first potentially habitable world outside of our own solar system.
	Walloped by heat wave, Greenland sees massive ice melt The heat wave that smashed high temperature records in five European countries a week ago is now over Greenland, accelerating the melting of the island's ice sheet and causing massive ice loss in the Arctic.
	African smoke is fertilizing Amazon rainforest and oceans, study finds A new study led by researchers at the University of Miami's (UM) Rosenstiel School of Marine and Atmospheric Science found that smoke from fires in Africa may be the most important source of a key nutrient—phosphorus—that acts as a fertilizer in the Amazon rainforest, Tropical Atlantic and Southern oceans.
	Scientists cook up new recipes for taking salt out of seawater As populations boom and chronic droughts persist, coastal cities like Carlsbad in Southern California have increasingly turned to ocean desalination to supplement a dwindling fresh water supply. Now scientists at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) investigating how to make desalination less expensive have hit on promising design rules for making so-called "thermally responsive" ionic liquids to separate water from salt.
	Fearing cougars more than wolves, Yellowstone elk manage threats from both predators Wolves are charismatic, conspicuous, and easy to single out as the top predator affecting populations of elk, deer, and other prey animals. However, a new study has found that the secretive cougar is actually the main predator influencing the movement of elk across the winter range of northern Yellowstone National Park.
	Quantum entanglement in chemical reactions? Now there's a way to find out Scientists have long suspected that a quantum phenomenon might play a role in photosynthesis and other chemical reactions of nature, but don't know for sure because such a phenomenon is so difficult to identify.
	Decades-old pollutants melting out of Himalayan glaciers Melting Himalayan glaciers are releasing decades of accumulated pollutants into downstream ecosystems, according to a new study.
	Cigarette smoke makes MRSA superbug bacterium more drug-resistant Cigarette smoke can make MRSA bacterial strains more resistant to antibiotics, new research from the University of Bath has shown.
	Key gene behind hallmark of Lou Gehrig's disease identified Inside the brains of patients with amyotrophic lateral sclerosis, a debilitating neurodegenerative disease, is a telltale sign that marks almost every case: clumps of toxic proteins.
	Shared e-scooters aren't always as green as other transport options People think of electric scooters, or e-scooters, as environmentally friendly ways to get around town. But a new study from North Carolina State University finds it's not that simple: shared e-scooters may be greener than most cars, but they can be less green than several other options.
	A voracious Cambrian predator, Cambroraster, is a new species from the Burgess Shale Palaeontologists at the Royal Ontario Museum and University of Toronto have uncovered fossils of a large new predatory species in half-a-billion-year-old rocks from Kootenay National Park in the Canadian Rockies. This new species has rake-like claws and a pineapple-slice-shaped mouth at the front of an enormous head, and it sheds light on the diversity of the earliest relatives of insects, crabs, spiders, and their kin. The findings were announced July 31, 2019, in a study published in Proceedings of the Royal Society B.
	Researchers build artificial cells that sense and respond to their environment The artificial cells could be used to sense changes in the body and respond by releasing drug molecules, or to sense and remove harmful metals in the environment.
