Science X Newsletter Week 27

Dear Reader ,

Here is your customized Science X Newsletter for week 27:

	Physicists provide support for retrocausal quantum theory, in which the future influences the past (Phys.org)—Although there are many counterintuitive ideas in quantum theory, the idea that influences can travel backwards in time (from the future to the past) is generally not one of them. However, recently some physicists have been looking into this idea, called "retrocausality," because it can potentially resolve some long-standing puzzles in quantum physics. In particular, if retrocausality is allowed, then the famous Bell tests can be interpreted as evidence for retrocausality and not for action-at-a-distance—a result that Einstein and others skeptical of that "spooky" property may have appreciated.
	Mars surface 'more uninhabitable' than thought: study Hopes of finding life on Mars, at least on the surface, were dealt a blow Thursday by a study revealing that salt minerals present on the Red Planet kill bacteria.
	Dying may not be as awful an experience as you think (HealthDay)—Does the very idea of death worry and frighten you? There may be reassurance from a new study that finds those fears might be exaggerated.
	Study shows our faces reveal whether we're rich or poor Put on a happy face, your success may depend on it, suggests a study by psychology researchers at the University of Toronto's Faculty of Arts and Science.
	New studies of ancient concrete could teach us to do as the Romans did Around A.D. 79, Roman author Pliny the Elder wrote in his Naturalis Historia that concrete structures in harbors, exposed to the constant assault of the saltwater waves, become "a single stone mass, impregnable to the waves and every day stronger."
	First battery-free cellphone makes calls by harvesting ambient power University of Washington researchers have invented a cellphone that requires no batteries—a major leap forward in moving beyond chargers, cords and dying phones. Instead, the phone harvests the few microwatts of power it requires from either ambient radio signals or light.
	Popular heartburn drugs linked to higher death risk Popular heartburn drugs called proton pump inhibitors (PPIs) have been linked to a variety of health problems, including serious kidney damage, bone fractures and dementia. Now, a new study from Washington University School of Medicine in St. Louis shows that longtime use of the drugs also is associated with an increased risk of death.
	Record-breaking 45-qubit quantum computing simulation run at NERSC When two researchers from the Swiss Federal Institute of Technology (ETH Zurich) announced in April that they had successfully simulated a 45-qubit quantum circuit, the science community took notice: it was the largest ever simulation of a quantum computer, and another step closer to simulating "quantum supremacy"—the point at which quantum computers become more powerful than ordinary computers.
	Menstruation doesn't change how your brain works—period A new study published in Frontiers in Behavioral Neuroscience today is setting out to change the way we think about the menstrual cycle. While it's often been assumed that anyone who's menstruating isn't working at top mental pitch, Professor Brigitte Leeners and her team of researchers have found evidence to suggest that that's not the case. They examined three aspects of cognition across two menstrual cycles, and found that the levels of oestrogen, progesterone and testosterone in your system have no impact on your working memory, cognitive bias or ability to pay attention to two things at once. While some hormones were associated with changes across one cycle in some of the women taking part, these effects didn't repeat in the following cycle. Overall, none of the hormones the team studied had any replicable, consistent effect on study participants' cognition.
	LHCb experiment announces observation of a new particle with two heavy quarks Today at the EPS Conference on High Energy Physics in Venice, the LHCb experiment at CERN's Large Hadron Collider has reported the observation of Ξcc++ (Xicc++) a new particle containing two charm quarks and one up quark. The existence of this particle from the baryon family was expected by current theories, but physicists have been looking for such baryons with two heavy quarks for many years. The mass of the newly identified particle is about 3621 MeV, which is almost four times heavier than the most familiar baryon, the proton, a property that arises from its doubly charmed quark content. It is the first time that such a particle has been unambiguously detected.
	Fastest stars in the Milky Way are 'runaways' from another galaxy A group of astronomers have shown that the fastest-moving stars in our galaxy - which are travelling so fast that they can escape the Milky Way - are in fact runaways from a much smaller galaxy in orbit around our own.
	Physicists read Maxwell's Demon's mind Pioneering research offers a fascinating view into the inner workings of the mind of 'Maxwell's Demon', a famous thought experiment in physics.
	Tesla: 1st Model 3 to be built Friday, sales start July 28 (Update) The first Tesla Model 3 electric car for the masses should come off the assembly line on Friday with the first deliveries in late July, the company's CEO says.
	Birth of wolf cubs in Mexico raises hopes for endangered species Mexican zoo officials are drooling over the birth of seven cubs of a species of endangered wolf.
	New system greatly speeds common parallel-computing algorithms The chips in most modern desktop computers have four "cores," or processing units, which can run different computational tasks in parallel. But the chips of the future could have dozens or even hundreds of cores, and taking advantage of all that parallelism is a stiff challenge.
	Carbon nanotubes mimic biology Proteins in lipid membranes are one of the fundamental building blocks of biological functionality. Lawrence Livermore researchers have figured out how to mimic their role using carbon nanotube porins.
	New study links antibiotic resistance to common household disinfectant triclosan Scientists from the University of Birmingham and Norwich Research Park have discovered a link between a major mechanism of antibiotic resistance and resistance to the disinfectant triclosan which is commonly found in domestic products.
	A future without fakes thanks to quantum technology Counterfeit products are a huge problem - from medicines to car parts, fake technology costs lives.
	Forgotten archives reveal street-level impact of 1918 Puerto Rico earthquake and tsunami Repair petitions filed in the wake of the 1918 Puerto Rico earthquake and tsunami, stored and forgotten in the San Juan archives for nearly 100 years, are giving scientists a house-by-house look at the damage wrought by the magnitude 7.3 event.
	Scientists get first direct look at how electrons 'dance' with vibrating atoms Scientists at the Department of Energy's SLAC National Accelerator Laboratory and Stanford University have made the first direct measurements, and by far the most precise ones, of how electrons move in sync with atomic vibrations rippling through an exotic material, as if they were dancing to the same beat.
