Science Sting Exposes Corrupt Journal Publishers

March 24th 2017

Physician and stethoscope

Spring break season is here, and, like a lot of beachgoers, science too is suffering some stings — albeit not of the jellyfish kind.

In the latest ploy, reported Wednesday, a group of researchers at the University of Wroclaw, in Poland, tried to seat a fictional scholar onto the editorial boards of 360 academic publications.

The goal: to test whether, with just a CV — full of fake scientific degrees — and a profile on Academia.edu as well as a fake university, some would accept a scholar named “Anna O. Szust” (which translates to “Anna, a Fraud” in English) as a member of their editorial boards.

And many did. The sting, reported in Nature, netted 48 journals — nearly all of which were so-called “predatory” journals. Such journals accept manuscripts without reviewing them, print them without editing them, and otherwise make a mockery of the scientific literature by pumping out low-quality work. Read more ..

Paper-based Thermometer Wraps around Objects Monitoring Temperatures on All Sides

March 20th 2017

Test Tubes

Researchers from the Renmin University of China have devised a very cheap and scalable temperature sensor made out of paper and traces of gold (for the electrodes) joined by a line of inkjet printer-ready ionic ink as the thermistor.

Publishing their results in the ACS Sensors journal under the title "Ultrafast Paper Thermometers Based on a Green Sensing Ink", they detail a very simple implementation where they leverage the benefits of paper as a flexible substrate and the ionic liquid, 1-ethyl-3-methyl imidazolium bis(trifluoromethylsulfonyl)imide ([EMIm][Tf2N]) for its non-volatile and hydrophobic nature.

Transferred to regular A4 paper by pen writing or inkjet printing, the ionic liquid holds onto the paper through the capillary effect, showing no leakage during bending and folding. The electrical conductivity of the ink trace is measured between two sputtered gold electrodes (5mm wide and 1.5cm long in the experiment) connected to an external power supply.

Recharge EVs from Under the Roadway

March 16th 2017

Traffic Jam

As more and more electric vehicles hit urban streets across the world, better battery-recharging solutions are desperately needed to improve range, keep costs low and boost user confidence.

Oren Ezer (CEO) and Hanan Rumbak (CTO) cofounded ElectRoad in 2013 to develop their unique twist on the concept of underground electric coils that recharge vehicles as they travel on the road.

In a few months, ElectRoad’s dynamic wireless electrification system is beginning a pilot project in Tel Aviv involving a short public bus route.

“The idea of electrifying vehicles from the road is trendy right now and you can see several companies trying to do a similar concept to us, but our technology is totally different, from the coils under the asphalt to the transfer of energy to the bus,” Ezer tells ISRAEL21c. Read more ..

The Quest to Crystallize Time

March 14th 2017

Taurus Molecular Cloud

Christopher Monroe spends his life poking at atoms with light. He arranges them into rings and chains and then massages them with lasers to explore their properties and make basic quantum computers. Last year, he decided to try something seemingly impossible: to create a time crystal.

The name sounds like a prop from Doctor Who, but it has roots in actual physics. Time crystals are hypothetical structures that pulse without requiring any energy—like a ticking clock that never needs winding. The pattern repeats in time in much the same way that the atoms of a crystal repeat in space. The idea was so challenging that when Nobel prizewinning physicist Frank Wilczek proposed the provocative concept in 2012, other researchers quickly proved there was no way to create time crystals.

But there was a loophole—and researchers in a separate branch of physics found a way to exploit the gap. Monroe, a physicist at the University of Maryland in College Park, and his team used chains of atoms they had constructed for other purposes to make a version of a time crystal. “I would say it sort of fell in our laps,” says Monroe.

An international team of scientists have engineered a molecule that uses light or electricity to convert the greenhouse gas carbon dioxide into carbon monoxide that could replace solar cells.

The team, led by Liang-shi Li at Indiana University (Bloomington, IN) with researchers from Nanchang University and the University of Science and Technology of China, used a nanographene-rhenium complex connected via an organic compound known as bipyridine to trigger a highly efficient reaction that converts carbon dioxide to carbon monoxide.

"If you can create an efficient enough molecule for this reaction, it will produce energy that is free and storable in the form of fuels," said Li, associate professor in the IU Bloomington College of Arts and Sciences' Department of Chemistry.

How Plants Evolved into Carnivores

February 7th 2017

Amazon rainforest

Any insect unlucky enough to land on the mouth-like leaves of an Australian pitcher plant will meet a grisly end. The plant's prey is drawn into a vessel-like ‘pitcher’ organ where a specialized cocktail of enzymes digests the victim.

Now, by studying the pitcher plant's genome—and comparing its insect-eating fluids to those of other carnivorous plants—researchers have found that meat-eating plants the world over have hit on the same deadly molecular recipe, even though they are separated by millions of years of evolution.

“We’re really looking at a classic case of convergent evolution,” says Victor Albert, a plant-genome scientist at the University of Buffalo, New York, who co-led the study. Read more ..

New Era of Exoplanet Discoveries In Store

January 24th 2017

New Earth Sized Planets

For astronomers seeking Earth twins around other stars, the exoplanet GJ 1132 b probably isn’t an identical sibling—but it may be the closest cousin yet found. It weighs in at just over one Earth mass, but circles its star in a warm orbit that could make it more like Venus than our own world. Moreover, its diameter is nearly 50 percent larger than that of Earth, suggesting it possesses a thick atmosphere. Now, after taking the closest-ever look at GJ 1132 b, a European collaboration has confirmed the presence of its atmosphere and found hints it might contain water and methane. The results are currently under review for publication in The Astrophysical Journal.

As mere discoveries of exoplanets become routine, efforts to learn more about them—their compositions, climates and histories—are moving to the fore, with studies of their atmospheres occupying center stage. Although astronomers detected the first exoplanet atmosphere more than 15 years ago, they have only managed to observe a handful ever since, mostly for very hot worlds as big as Jupiter or even larger. With their first glimpse of GJ 1132 b’s alien air, astronomers are now entering a new frontier as they examine the atmospheres of smaller, more Earth-like worlds.

Research and Development Chemistry

The Pentagon’s research and development division, DARPA—the creative force behind the internet and GPS—retooled itself three years ago to create a new office dedicated to unraveling biology’s engineering secrets. The new Biological Technologies Office (BTO) has a mission to “harness the power of biological systems” and design new defense technology. Over the past year, with a budget of about $296 million, it has been exploring challenges including memory improvement, human–machine symbiosis and speeding up disease detection and response.

DARPA, or the Defense Advanced Research Projects Agency, is hoping for some big returns. The director of its BTO, neuroprosthetic researcher Justin Sanchez, recently spoke with Scientific American about what to expect from his office in 2017, including work on neural implants to aid healthy people in their everyday lives and other advances that he says will “change the game” in medicine.

NASA Should Build a Superhighway in Space

January 5th 2017

Mars & Earth, Christopher Leather U Chicago

Donald Trump will take power any minute now, and we need to take advantage of the change in the White House to change NASA's focus.

Why? NASA needs to get out of the rocket business and shift its attention to a permanent space transport infrastructure, an Eisenhower-style highway in the sky. An infrastructure with:

  • Gas stations (propellant depots),
  • Rest stops and permanent housing—roomy human habitats with windows and vegetable gardens,
  • Truck stops and freight yards—logistics bases with cargo-handling equipment,
  • Trucks, SUVs, and dune buggies—Moon-and-Mars ground vehicles; plus tugs to haul loads around in space,
  • Fuel production equipment—units to turn the water of the Moon and Mars into rocket fuel, breathable oxygen, and drinkable water,
  • Units to turn the carbon dioxide in Mars' atmosphere into plastics, graphene, and carbon fiber with which 3-d printers can build more habitats, tools, and rovers—more trucks, SUVs and dune buggies.
  • Units to turn the rusty rocks lying around on the Martian surface into high strength steel for habitats. 

Why move NASA into space highway construction? Because no one else will do it. And our future in space depends on it. Our future share in a space economy that United Launch Alliance (a joint venture rocket company from Boeing and Lockheed Martin) estimates will be worth $2.7 trillion in thirty years.

Do Dogs Know Other Dogs Are Dogs?

Do you see dogs everywhere?

My ears perk up to the jingle jangle of metal-on-metal, hopeful that it predicts a dog and his collar, disappointed when it turns out to be keys on a belt (boring).

A person walking down the street with their arm outstretched holds the promise of a leash with a dog on the other end (sometimes it’s a stroller holding a kid. Oh well).

From a distance, my eyes play a cruel trick on me, where shopping bags are dogs and dogs are shopping bags until I get close enough and one wins out (obviously I'm rooting for the dog).

But catch any part of a tail, and I know I'm in. You could say my motto is, “dog, until proven otherwise.”

How about dogs?

Does a dog know, merely by sight, that an approaching being is a fellow dog? Before you answer, remember this: Canis familiaris is the least uniform species on the planet. Members of this species come in a wide range of body shapes and sizes from itty bitty teeny weeny to absolutely ginormos. Adult members of this species appear as tight little packages, huge weightlifters, lean ballerinas, elongated hotdogs and everything in between.

Hunting Dark Matter between the Ticks of an Atomic Clock

December 21st 2016

Massive black hole disrupting star formation

Dark matter is thought to make up some five sixths of all matter in the universe. Yet incredibly sophisticated projects ranging from the most powerful atom smasher ever built to vats of chilly liquid xenon have failed to find a trace of it. But now some scientists are hoping atomic clocks, the most precise timekeepers ever made, could be used to help explain this elusive phenomenon.

Many physicists believe dark matter is an invisible substance whose predicted gravitational effects on known matter would help explain a variety of cosmic mysteries, such as why galaxies can spin as fast as they do without flying apart. Despite its apparently colossal importance to the very structure of the universe, however, no one knows anything for certain about what it might be composed of or where it came from.

New Diagnosis for Parkinsons Advanes the Cause

December 15th 2016

walking-cane

Doctors diagnose as many as 60,000 new cases of Parkinson’s disease (PD) every year in the United States. Yet diagnosing PD with certainty can take years — long after early signs and symptoms have appeared.

The Israeli startup BioShai has a game-changing product on the horizon: PDx, the world’s first simple blood test for the early diagnosis of PD.

The test results can be combined with clinical data, providing a more accurate diagnosis to help physicians decide on the best course of treatment at a much earlier stage.

More than 10 million people worldwide are living with this chronic and progressive movement disorder caused by the malfunction and death of neurons that produce dopamine, a chemical that coordinates the brain’s control of movement and coordination.

“Having a diagnosis at an earlier stage can lead to a more precise treatment and a higher quality of life for the patient,” says BioShai CEO Jennifer Yarden, who has a PhD in medical science and formerly was responsible for clinical and commercial development of diagnostic assays and kits at Glycominds. Yarden is also CEO and cofounder of Curewize Health.

“Offering a simple and inexpensive test for the diagnosis of Parkinson’s is considered essential for the development of neuroprotective therapy,” she explains, “because by the time a patient has the many movement symptoms associated with Parkinson’s, a majority of the dopamine-producing neurons are lost or become impaired by the disease.”

Tuna’s Declining Mercury Contamination Linked to U.S. Shift Away from Coal

November 30th 2016

School of tuna

Levels of highly toxic mercury contamination in Atlantic bluefin tuna are rapidly declining, according to a new study. That trend does not affect recommended limits on consumption of canned tuna, which comes mainly from other tuna species. Nor does it reflect trends in other ocean basins. But it does represent a major break in the long-standing, scary connection between tuna and mercury, a source of public concern since 1970, when a chemistry professor in New York City found excess levels of mercury in a can of tuna and spurred a nationwide recall. Tuna consumption continues to be the source of about 40 percent of the mercury contamination in the American diet. And mercury exposure from all sources remains an important issue, because it causes cognitive impairment in an estimated 300,000 to 600,000 babies born in this country each year.

The Stealthy Gallium War

F-35

War is going on over special integrated circuits based on a material called Gallium Nitrite. Winning this war will effect not only the United States national security, but also its ability to protect key global partners in Europe, the Middle East, and Asia.
Unfortunately the battle for Gallium Nitrite is very complicated, because the material has extensive commercial as well as military application.

But perhaps the single most important use for Gallium Nitrite is for detecting stealth aircraft and defeating long range weapons including so-called Beyond Visual Range (BVR) missiles launched from aircraft.

The United States is totally committed to stealth as the game changing technology of the present and future.  So deeply is the United States committed, that the only air superiority multi-mission aircraft being produced today is the F-35 Joint Strike Fighter (JSF).  The JSF is hugely costly and less stealthy than its big brother the F-22, but the F-22 was sacrificed so the JSF program could be financed, so mostly everything going forward hangs on this single airplane.

Plants Can Now Be Used to Detect Explosives

November 3rd 2016

Leaf

Scientists at MIT have successfully bioengineered spinach to wilt if explosive material is detected in groundwater, according to a paper put out in the prestigious Journal of Nature Materials.

The research paper is titled “Nitroaromatic detection and infrared communication from wild-type plants using plant nanobionics.”

Here, we demonstrate that living spinach plants (Spinacia oleracea) can be engineered to serve as self-powered pre-concentrators and autosamplers of analytes in ambient groundwater and as infrared communication platforms that can send information to a smartphone,” the paper’s authors said their introduction.

As the plant absorbs water from the ground it will also absorb the explosive material. Thanks to deliberately created adaptations in the plant’s leaves, the plant will wilt in response to the presence of the explosive compounds.

Fixed sensors nearby will monitor the spinach using infrared technology and will pick up on the change in the plant.  

The project was funded by DARPA, the body of the U.S. military in charge of research and development. It has an annual budget of nearly $3 billion and funds a vast array of different technologies that either have or could potentially have military application. Read more ..

IoT Growing Faster Than the Ability to Defend It

With this year’s approaching holiday gift season the rapidly growing “Internet of Things” or IoT—which was exploited to help shut down parts of the Web this past Friday—is about to get a lot bigger, and fast. Christmas and Hanukkah wish lists are sure to be filled with smartwatches, fitness trackers, home-monitoring cameras and other wi-fi–connected gadgets that connect to the internet to upload photos, videos and workout details to the cloud. Unfortunately these devices are also vulnerable to viruses and other malicious software (malware) that can be used to turn them into virtual weapons without their owners’ consent or knowledge.

The recent distributed denial of service (DDoS) attacks—in which tens of millions of hacked devices were exploited to jam and take down internet computer servers—is an ominous sign for the Internet of Things. A DDoS is a cyber attack in which large numbers of devices are programmed to request access to the same Web site at the same time, creating data traffic bottlenecks that cut off access to the site. In this case the still-unknown attackers used malware known as “Mirai” to hack into devices whose passwords they could guess, because the owners either could not or did not change the devices’ default passwords.

Four particular viruses now stand out to virologists and epidemiologists, although it is not certain any of the ailments will become the next Zika or West Nile virus. But researchers give several reasons to keep a close eye on this quartet:

 

MAYARO

“For 10 years now I’ve been thinking that Mayaro is right on the cusp of being able to amplify in humans and being transmitted efficiently by Aedes aegypti mosquitoes,” says Scott Weaver, a virologist  at The University of Texas Medical Branch at Galveston. Mayaro causes a disease that is clinically indistinguishable from the mosquito-borne chikungunya virus: fever, chills, rash and the characteristic joint pain that can last longer than a year. It does matter, though, which of these viruses circulates in your body. Once there are vaccines against Mayaro and chikungunya, and drugs to treat them (so far there are none), they will likely be virus-specific.

The Australian telecommunications provider Telstra and telematics group Cohda Wireless have successfully tested a range of Vehicle-to-Infrastructure (V2I) applications over 4G networks. V2I, and more general, V2X is regarded as an enabling technology for intelligent connected road transport systems that will in turn open the path to better traffic management with less congestions, coordinated autonomous vehicle operation and more efficient use of the road infrastructure.

During their trials, the partners tested applications involving vehicles talking to infrastructure (such as traffic lights), vehicles communicating with other vehicles, and vehicles talking to vulnerable road users such as cyclists and pedestrians. In detail, the applications included alerting a driver to roadworks ahead, giving green light priority to high priority vehicles, and testing optimal green light timing where the vehicle is informed of the optimal speed to approach a traffic light so that that they get a green light when they arrive, therefore allowing a more continuous flow of traffic.

How Israel is Saving the Honeybees

Honeybees across the world are in a sticky situation. Their numbers are dwindling dramatically due to colony collapse disorder (CCD) for reasons that are not fully understood. Yet the honeybee population in Israel is holding steady.

That’s great news at this time of year, when sweet Jewish New Year dishes push honey demand to its peak. And most importantly, bees play a crucial role in agriculture by pollinating vegetables and fruits.

Israel takes measures to ensure that its bee population declines no more than 10 percent each year, compared to 30%-50% in the United States, where the problem is so severe that Häagen-Dazs ice cream has donated $1 million to honeybee research since 2008, and President Obama initiated a national strategy to promote bee health.

New Earth Sized Planets

It was just over 20 years ago—a blink of a cosmic eye—that astronomers found the first planets orbiting stars other than our sun. All these new worlds were gas-shrouded giants like Jupiter or Saturn and utterly inhospitable to life as we know it. But for years each discovery was dutifully reported as front-page news, while scientists and the public alike dreamed of a day when we would find a habitable world. An Earth-like place with plentiful surface water, neither frozen nor vaporized but in the liquid state so essential to life. Back then the safe bet was to guess that the discovery of such a planet would only come after many decades, and that when a promising new world’s misty shores materialized on the other side of our telescopes, it would prove too faraway and faint to study in any detail.

Evidently the safe bet was wrong. On Wednesday astronomers made the kind of announcement that can only occur once in human history: the discovery of the nearest potentially habitable world beyond our solar system. This world may be rocky like ours and whirls in a temperate orbit around the sun’s closest stellar neighbor, the red dwarf star Proxima Centauri just over four light-years away.

This year, the security experts turned their attention to injecting rogue messages into a vehicle’s CAN bus, which resulted in a full-speed attack on the Jeep’s steering and acceleration.

Instead of getting into the guts of a car wirelessly, Miller and Valasek this year used a laptop directly plugged into the Jeep’s CAN network through a port under its dashboard. They confirmed that they used the patched Jeep for this hacking. Read more ..

Juno Arrives at Jupiter

July 8th 2016

Jupiter

NASA's Juno spacecraft has successfully entered orbit around Jupiter. At 8:53 P.M. Pacific time, ground controllers received a telemetry tone of 2,327 hertz -- equivalent to the highest D note on a piano keyboard—indicating that Juno's 35-minute engine burn had slowed the spacecraft enough to slip into the giant planet’s gravitational embrace. Launched in 2011 on a nearly five-year interplanetary voyage, Juno is only the second spacecraft to ever orbit Jupiter, after the Galileo mission that explored the giant planet from 1995 to 2003. During its capture into orbit Juno passed just 4,490 kilometers above the Jovian cloud tops, so close that the planet filled half its sky. Even so, Jupiter is so immense that an astronaut riding along would have seen only about 5 percent of the planet’s cloud-shrouded face.

At 9:50 P.M., the maneuver was officially complete as the spacecraft turned its solar arrays back toward the sun. “I won't exhale until we’re sun-pointed again,” Juno's principal investigator Scott Bolton had said at a press conference earlier in the day.

The spacecraft plummeted in from interplanetary space over Jupiter's north pole at about 7:30 P.M., falling ever faster as it plunged deeper into the planet’s gravitational field. Just two days ago its speed relative to Jupiter was nine kilometers per second; midday yesterday, 12 kilometers per second; and by the rocket burn, 54 kilometers per second. The burn reduced its speed by just 1 percent, but that was enough. (Theoretically, the spacecraft was captured by the planet at 8:38 P.M., about halfway through the burn, but confirmation did not come until later.) After skimming so close to Jupiter's upper atmosphere, the spacecraft soared back up from the planet’s cloud tops at about 9:30 P.M. into a looping, elongated orbit out to 8.1 million kilometers.

Fast-tracking Innovation for Spinal Correction

May 12th 2016

ApiFix, a Treadlines company, was awarded Best Start-Up 2012 by Israel's Office of the Chief Scientist of the Ministry of Economy for a less invasive, less painful, and less costly option for spine curvature correction. Apifix is developing a truly breakthrough minimally invasive deformity correction system for patients with Adolescent Idiopathic Scoliosis (AIS).

Today’s gold standard for correcting spinal deformities involves fusing an average of 10 motion levels using a large number of screws in a surgical procedure that lasts an average of six hours and costs upward of $100,000. 

As opposed to the current procedure, ApiFix uses only two screws to support its ratchet-based, small expandable rod inserted through a small incision in the patient’s back. In addition to the smaller incision, a shortened surgery time (1 hour vs. 4-6 hours) and reduced hospitalization stay.

I interviewed Uri Arnin, Founder and CEO and chief innovator of ApiFix Ltd. about the success of his company and the distinctive characteristics of the Israeli biotech cluster. “We have close communication between companies of the same field and willingness to assist each other. The same subcontractors and advisers support similar companies and help to share the experience,” Arnin said. “We have a fast turnaround of production cycles, due to personal relationship with suppliers.”   Read more ..

Millions in IBM Endicott Pollution Claims Paid

January 15th 2016

Computer chips

IBM has paid several million dollars to hundreds of people who have been seeking compensation for claims related to chemical contamination at the company’s Endicott microelectronics facility. The company and many of the plaintiffs who had taken IBM to court last year agreed to a settlement of the lawsuit filed nearly a decade ago. Endicott Mayor John Bertoni told WNBF News he has heard that compensation checks have been received in recent days. Although IBM reportedly had agreed to pay settlements totaling several million dollars to several hundred plaintiffs, it’s not known how much money is now being paid out. Business owners in the lawsuit received more than owners of residential property near the North Street manufacturing complex.

Two law firms – Levene Gouldin and Thompson of Vestal and Faraci Lange of Rochester – mailed out settlement checks in late December. Some plaintiffs had alleged spills of the chemical TCE may have resulted in illnesses and deaths. The lawsuit also contended property values dropped and nearby businesses were harmed because of the contamination. IBM was founded more than a century ago in Endicott. The company now is based in Westchester County. Read more ..


The Refugee Crisis

It is Possible to Vet Syrian Refugees

January 4th 2016

Syrian Refugees


With the flood of refugees from the Middle East and North Africa overwhelming Europe, and with the Obama administration allowing large numbers to come to the United States, there is a justifiable fear that embedded in the ranks of the refugees are trained terrorists.
Until now, identifying embedded terrorists has been nearly an impossible challenge.  People have called for better "vetting," but to "vet" means to look back at people's history based on their documentation. For most people, certainly for most Syrians, there is no "back" - even a legitimate passport can't be verified with Passport Control in Damascus. With whom would one check local police, employment or education records? Read more ..

“I call heaven and earth to record this day against you, that I have set before you life and death, blessing and cursing: therefore choose life, that both thou and thy seed may live”
Deuteronomy 30:19

On my many trips to Israel as the national chairman of the Jewish National Fund’s Doctors for Israel, I have observed the amazing life-saving and life-enhancing advances of Israeli medicine and discussed the future of medicine and science with many leading scientists.

I visited the makers of Rewalk robotic exoskeleton (featured on the hit TV show “Glee”) that enables paraplegic runners in London and Tel Aviv to complete marathons and spent time at Given Imaging’s PillCam capsule endoscopy company. Among other Israeli medical leaders are Itamar Medical’s fingertip monitors for sleep disorders and cardiac issues, IceCure Medical’s IceSense3 and Surpass Medical’s NeuroEndoGraft.  Read more ..

Facebook Unveils Solar-Powered Internet-Beaming Drone

August 3rd 2015

Random Radio Telescope Array

Social networking giant Facebook (Cambridge, MA) has unveiled a full-scale version of its solar-powered drone designed to provide Internet connectivity to remote regions of the world.

Code-named Aquila, and with a wingspan of a Boeing 737, the connected drone is designed to fly for three months at a time - above weather systems and other aircraft - and create about a 30-mile (50-km) communications radius. It will use free-space laser communication technology to send and receive data to other drones and base stations at up to tens of gigabits per second.

According to the company, the drone will fly at a varying altitude of between 60,000 and 90,000 feet (18 to 27 km). During the day it will operate at its maximum height to capture as much of the sun's energy as possible, while at night, when not receiving solar energy, it will descend to its lower altitude to conserve energy.

Bioengineers Invent Engine Powered By Water Vapor and Artificial Muscles

June 17th 2015

Caribbean Sea Shore

Bioengineers have invented the world’s first engine that runs on energy created from the process of natural water evaporation at room temperature, by utilizing cleverly engineered artificial muscles.

The small device, created by researchers at Columbia University, is a fully functional engine which can generate 1.8 microwatts of energy – enough to power LED lights or even a tiny car – all for the cost of $5. It works by drawing power from a process never considered to be a potential energy source before.

“Engineered systems rarely, if ever, use evaporation as sources of energy, despite myriad examples of such adaptations in the biological world,” a paper published in Nature by a team of authors, including researchers Xi Chen, Ozgur Sahin and others, claimed.

3-D Printed Aircraft Parts Will Save Weight, Fuel Says Study

June 5th 2015

United Airlines jet liner

The team, led by Eric Masanet who heads the Energy and Resource Systems Analysis Laboratory at Northwestern, used aircraft industry data to study the life-cycle environmental effects of using 3-D printing - or 'additive manufacturing' - for building select metal aircraft parts. While 3-D printing has begun to be adopted by the airline industry, the study concluded that widespread adoption of the technique to print lighter and higher-performance aircraft parts could significantly reduce manufacturing waste and the weight of the airplane, resulting in fuel and cost saving as well as a reduction in carbon emissions.

"We have suboptimal designs because we're limited by conventional manufacturing,” Masanet says. “When you can make something in layer-by-layer fashion, those constraints diminish." Read more ..

Cancer Drugs May Prevent Down Syndrome and Fragile X

May 26th 2015

A class of FDA-approved cancer drugs may be able to prevent problems with brain cell development associated with disorders including Down syndrome and Fragile X syndrome, researchers at the University of Michigan Life Sciences Institute have found.

The researchers' proof-of-concept study using fruit fly models of brain dysfunction was published today in the journal eLife. They show that giving the leukemia drugs nilotinib or bafetinib to fly larvae with the equivalent of Fragile X prevented the wild overgrowth of neuron endings associated with the disorder. Meanwhile, the drugs—both tyrosine-kinase inhibitors—did not adversely affect the development or neuronal growth in healthy flies. Read more ..

When UN Secretary General Ban Ki-moon visited the sukkah of Israeli President Reuven Rivlin during the Jewish harvest holiday last October, he was treated to a demo of a machine the government has given to Bedouin families to convert organic waste into clean biogas for cooking, heating and lighting, as well as organic liquid crop fertilizer.

"He got very excited and told us, 'Millions of women and children die each year due to indoor smoke from open fires. This is just the thing they need. The UN should be purchasing these units!' recalls Ami Amir of HomeBioGas, which develops and manufactures a new class of anaerobic biodigesters to convert organic waste to clean renewable energy. He asked us to be in touch with the UN’s Food and Agriculture Organization to see where and when our systems could be deployed.” Read more ..
