Science X Newsletter Week 24

Dear Reader ,

Here is your customized Phys.org Newsletter for week 24:

	Engineers develop state-by-state plan to convert US to 100% clean, renewable energy by 2050 One potential way to combat ongoing climate change, eliminate air pollution mortality, create jobs and stabilize energy prices involves converting the world's entire energy infrastructure to run on clean, renewable energy.
	Data scientists find connections between birth month and health Columbia University scientists have developed a computational method to investigate the relationship between birth month and disease risk. The researchers used this algorithm to examine New York City medical databases and found 55 diseases that correlated with the season of birth. Overall, the study indicated people born in May had the lowest disease risk, and those born in October the highest. The study was published in the Journal of American Medical Informatics Association.
	At near absolute zero, molecules may start to exhibit exotic states of matter The air around us is a chaotic superhighway of molecules whizzing through space and constantly colliding with each other at speeds of hundreds of miles per hour. Such erratic molecular behavior is normal at ambient temperatures.
	Engineers develop a computer that operates on water droplets Computers and water typically don't mix, but in Manu Prakash's lab, the two are one and the same. Prakash, an assistant professor of bioengineering at Stanford, and his students have built a synchronous computer that operates using the unique physics of moving water droplets.
	Physicists demonstrate new violations of local realism (Phys.org)—Erwin Schrödinger once famously stated that quantum entanglement is "the characteristic trait of quantum mechanics" that distinguishes it from classical theories. Now in a new paper, physicists have demonstrated a new family of entangled states that violates the principle of "local realism"—an intuitive concept that is a standard feature of classical theories, but disturbingly at odds with quantum theory.
	Scientists see ripples of a particle-separating wave in primordial plasma Scientists in the STAR collaboration at the Relativistic Heavy Ion Collider (RHIC), a particle accelerator exploring nuclear physics and the building blocks of matter at the U.S. Department of Energy's Brookhaven National Laboratory, have new evidence for what's called a "chiral magnetic wave" rippling through the soup of quark-gluon plasma created in RHIC's energetic particle smashups.
	Injectable gel fills wounds and promotes tissue regeneration Researchers from the UCLA Henry Samueli School of Engineering and Applied Science have developed an injectable hydrogel that helps skin wounds heal more quickly. The material creates an instant scaffold that allows new tissue to latch on and grow within the cavities formed between linked spheres of gel.
	Dogs snub people who are mean to their owners, study finds Dogs do not like people who are mean to their owners, Japanese researchers said Friday, and will refuse food offered by people who have snubbed their master.
	Study finds decreased social anxiety among young adults who eat fermented foods Psychologists have traditionally looked to the mind to help people living with mental health issues. But a recent study led by William & Mary researchers shows that the stomach may also play a key role, suggesting that the old adage "you are what you eat" is more than a cliché.
	Injectable electronics holds promise for basic neuroscience, treatment of neuro-degenerative diseases It's a notion that might be pulled from the pages of science-fiction novel - electronic devices that can be injected directly into the brain, or other body parts, and treat everything from neurodegenerative disorders to paralysis.
	Blind quantum computing method surpasses efficiency 'limit' (Phys.org)—Demonstrating that limits were made to be broken, physicists have overcome what was previously considered to be a natural and universal limit on the efficiency of a quantum cryptography task called blind quantum computing. The new method offers significant efficiency improvements and, in some cases, requires exponentially fewer communication resources to implement than previous methods did.
	40-year-old algorithm proven the best possible Comparing the genomes of different species—or different members of the same species—is the basis of a great deal of modern biology. DNA sequences that are conserved across species are likely to be functionally important, while variations between members of the same species can indicate different susceptibilities to disease.
	Quantum Cheshire Cat effect may be explained by standard quantum mechanics (Phys.org)—"A grin without a cat" is how Lewis Carroll describes the Cheshire Cat's mysterious way of disappearing while leaving its grin behind in his 1865 classic, Alice in Wonderland. The fanciful character raises a question that has captured physicists' attention over the past few years: can an object be separated from its properties?
	MX3D is to 3D-print a steel bridge over water in Amsterdam MX3D is an R&D startup focused on 3D-printing metals and resin in mid-air, without the need for support structures. They pride themselves in "robotic technology with which we can 3D print beautiful, functional objects in almost any form." Now they say "We are going to print a steel bridge in Amsterdam." The robots will be printing in steel and the robots will print that bridge over water in Amsterdam. The project team sees the metal bridge as serving as a showcase for present-day capabilities in software, engineering and design.
	Ancient DNA reveals how Europeans developed light skin and lactose tolerance Food intolerance is often dismissed as a modern invention and a "first-world problem". However, a study analysing the genomes of 101 Bronze-Age Eurasians reveals that around 90% were lactose intolerant.
	A practical guide to countering science denial It should go without saying that science should dictate how we respond to science denial. So what does scientific research tell us?
	Counting people with WiFi Researchers in UC Santa Barbara professor Yasamin Mostofi's lab are proving that wireless signals can do more than provide Internet access. They have demonstrated that a WiFi signal can be used to count the number of people in a given space, leading to diverse applications, from energy efficiency to search-and-rescue.
	Inventor Jake Dyson has LED light with cooling solution Jake Dyson, son of Dyson founder James, has staked out his corner in the engineering innovation world with a focus on LED solutions, the Jake Dyson Light. He has in turn been doing a rethink on the characteristics and function of a desk light.
Evolution is unpredictable and irreversible, biologists show Evolutionary theorist Stephen Jay Gould is famous for describing the evolution of humans and other conscious beings as a chance accident of history. If we could go back millions of years and "run the tape of life again," he mused, evolution would follow a different path.
	Nuts and peanuts may protect against major causes of death A paper published today in the International Journal of Epidemiology confirms a link between peanut and nut intake and lower mortality rates, but finds no protective effect for peanut butter. Men and women who eat at least 10 grams of nuts or peanuts per day have a lower risk of dying from several major causes of death than people who don't consume nuts or peanuts.
