Science X Newsletter Week 19

Dear Reader ,

Here is your customized Phys.org Newsletter for week 19:

	Researchers create first neural-network chip built just with memristors (Phys.org)—A team of researchers working at the University of California (and one from Stony Brook University) has for the first time created a neural-network chip that was built using just memristors. In their paper published in the journal Nature, the team describes how they built their chip and what capabilities it has.
	Nikola Labs phone case harvests back wasted energy If you click on the Nikola Labs site you will find an announcement that the group plans to go up on Kickstarter soon and they invite your email signup to learn more. Then at the bottom of the page is an icon-centric presentation of HOW IT WORKS, although "IT" has no noun. What we are shown is that a WiFi signal points to a RF harvesting antenna which points to DC power. The last sentences are, "Nikola Technology efficiently converts RF signals like Wi-Fi, Bluetooth, and LTE into DC power using its proprietary energy harvesting circuit. The result is usable energy that can provide power to mobile devices wirelessly."
	Mozilla says HTTPS is the way forward for the Web The web developer community can hear a rallying cry loud and clear :Let's hear it for web security. Mozilla, the group behind the browser Firefox, is turning up the volume by saying enough's enough with non-secure HTTP. The Foundation has taken a move in order to protect users from snoopers.
	BioBots bioprinter to complement cutting-edge research A high-resolution desktop 3D bioprinter that builds functional 3D living tissue was shown recently at TechCrunch Disrupt in New York. The machine is significant as a less expensive way for researchers to build 3D functional structures of living tissue. BioBots is the name of the company behind the printer.
	GoSun solar grill offers a greener way to barbecue A group led by inventor Patrick Sherwin has posted a Kickstarter project named GoSun Grill, it uses sunlight to charge a thermal battery which in turn is used to cook food inside a glass vacuum tube. The difference between this grill and other solar cookers is that it will continue to work if it gets cloudy out, or even after the sun goes down.
	Keeping legalized marijuana out of hands of kids As the realities of legalized marijuana take hold in four states and the District of Columbia, legislators and regulators could learn a lot from the successes—and failures—of the tobacco and alcohol industries in keeping their harmful products out of the hands of children and adolescents.
	New study suggests prominent role for pharmacies in reducing asthma-related illness A new study shows how pharmacies might collaborate with physicians and families to reduce asthma-related illness.
	Starfish babies offer glimmer of hope amid mass die-off Emerging from a recent dive 40 feet below the surface of the Puget Sound, biologist Ben Miner wasn't surprised by what he found: The troubling disease that wiped out millions of starfish up and down the West Coast had spread to this site along the rocky cliffs of Lopez Island.
	Botswana's marauding elephants trigger hunting ban debate Surveying her destroyed cornfield in northern Botswana, Minsozie Kasaira wishes for a return to the days of elephant hunting.
	Costa Rica scare as ship carrying chemicals sinks Costa Rican authorities declared an emergency after a ship carrying 180 tons of ammonium nitrate sunk off the country's Pacific coast.
	Mumblehard targets servers running Linux and BSD Security watchers are talking about a family of malware that infects Linux and BSD servers. Marc-Etienne M. Léveillé, ESET malware researcher, has provided details about Linux/Mumblehard, which targets servers running Linux and BSD.
	Multicolor meta-hologram produces light across entire visible spectrum (Phys.org)—There are many different ways to generate a hologram, each with its own advantages and disadvantages. Trying to maximize the advantages, researchers in a new study have designed a hologram made of a metamaterial consisting of aluminum nanorods that can produce light across the entire visible spectrum, and do so in a way that yields brighter images than other methods.
	Be a responsible camper When you camp out, take steps to reduce your impact on the environment, experts advise.
	High-value research of 2014 presented for internal medicine (HealthDay)—Articles relating to atrial fibrillation, venous thromboembolism, acute bronchitis, ambulatory blood pressure monitoring for hypertension screening, and guidelines relevant to generalist practice are included in a special update summary published online April 30 in the Annals of Internal Medicine.
	Out-of-hospital cardiac arrest outcomes vary by time to CPR (HealthDay)—For patients with out-of-hospital cardiac arrest (OHCA), outcomes differ by time to first cardiopulmonary resuscitation (CPR) and first documented rhythm, according to a study published online April 30 in Circulation: Cardiovascular Quality and Outcomes.
	FDA approves raplixa to help control surgical bleeding (HealthDay)—Raplixa (human fibrin sealant) has been approved by the U.S. Food and Drug Administration to help control bleeding during surgery, the agency said in a news release.
	ACOG: Pregnant women may believe E-cigarettes OK (HealthDay)—More than 40 percent of pregnant women surveyed think electronic cigarettes are less harmful than tobacco cigarettes, according to a new study. The results of the study are scheduled to be presented at the annual meeting of the American College of Obstetricians and Gynecologists, held from May 2 to 6 in San Francisco.
	Comcast now has more Internet than cable customers Just before its $45 billion deal with Time Warner Cable collapsed over regulators' fears about a giant cable company's control over the Web, Comcast was racking up more Internet customers.
	Alcohol corrupts body movements by inhibiting sodium-potassium pumps in the cerebellum Alcohol is used, and in some cases abused, by millions of people worldwide. How it acutely changes brain function to cause inebriation, and chronically changes brain function to cause dependency, is largely unknown. The latter especially can destroy lives and families. Understanding the mechanisms of action is the foundation to countering them. A "sobriety pill" would have immense medical, sociological and commercial potential.
	'Performance enhancing' drugs decrease performance Doping is damaging the image of sport without benefitting athletes' results, according to University of Adelaide research.
