The Race for Autonomous Vehicles

Ford Explores Communication Between Autonomous Vehicles And Humans

September 19th 2017

Automated driving Mercedes Benz

Together with the Virginia Tech Transportation Institute, Ford Motor Company is testing a system that enables autonomous vehicles and human drivers to communicate with each other. Ford uses a car that appears to be driving autonomously.

In everyday traffic, human road users communicate intuitively by small gestures: a short wave or nod is often enough to indicate that the other person is allowed to pass through. This element of communication is missing in autonomous cars. Ford is now testing how such a simple "gesture language" between robocar and human road users could look like.

When Daimler sent an autonomous Mercedes through the traffic in 2013, a fundamental weakness of the electronic chauffeurs became obvious: An elderly couple was waiting at a pedestrian crossing. The automatic Mercedes stopped allow the pedestrian to cross.

However, the two pedestrians made a gesture to make it clear that they would prefer the car to drive first. The computer on board the Mercedes didn't understand the hint and insisted on not continuing until after the pedestrians. The deadlock situation could only be resolved after the human safety driver intervened.

Leaf Sensors tells Farmers when Plants are Thirsty

September 4th 2017

Leaf

Researchers at Penn State's College of Agricultural Sciences (University Park, PA) have developed a plant leaf sensor that can continuously monitor water stress in plants.

Continuous monitoring of plant "water stress" can help let farmers know when to activate irrigation systems, preventing both water waste and parched plants. Traditionally this has been done by measuring soil moisture content or with the use of models that calculate ground surface evaporation and plant transpiration .

But, say the researchers, water-use efficiency could be improved with new technology that is able to more accurately detect when plants need to be watered. The leaf sensor they developed can do just that, by simultaneously measuring, for the first time, both leaf thickness and leaf electrical capacitance - the ability of a leaf to store a charge.

"Leaf thickness is like a balloon — it swells by hydration and shrinks by water stress, or dehydration," says lead researcher Amin Afzal. "The mechanism behind the relationship between leaf electrical capacitance and water status is complex. Simply put, the leaf electrical capacitance changes in response to variation in plant water status and ambient light. So, the analysis of leaf thickness and capacitance variations indicate plant water status — well-watered versus stressed."

The researchers performed their tests by mounting leaf sensors on random leaves of a tomato plant in a growth chamber under controlled temperature and lighting conditions. Measurements were recorded at five-minute intervals.

Genetically Modified Moths Fly to New York

August 29th 2017

Moth

How do you fight an insect that inflicts billions of dollars of crop damage every year, an invader that has spread to every inhabited continent and has a talent for evolving resistance to every new chemical designed to poison it? Maybe—just maybe—by releasing more of the same insect.

This summer thousands of moths will be taking to the sky over a cabbage patch in upstate New York. Bred in a laboratory, the male bugs carry a gene designed to kill progeny they sire with wild female moths feasting on the cabbage. This genetic time bomb is an emerging tool for keeping agricultural pest populations in check, made possible by ever-improving methods for editing DNA.

Over the coming months, before winter kills the moths, researchers at Cornell University will monitor how well their modified pets compete against wild cousins for mates. If all goes well, this small-scale experiment could be a step toward commercializing the genetically engineered diamondback moths, made by a British company called Oxitec. Read more ..


The Harvey Catastrophe

Hurricane Harvey: Why Is It So Extreme?

August 29th 2017

Hurricane Isabel

Hurricane Harvey is drowning southeastern Texas for the fourth day, putting a vast area under feet of water. Experts say Harvey has been stuck longer in one place than any tropical storm in memory. That is just one of the hurricane’s extremes; the storm is off the charts by many measures.

Why did Hurricane Harvey so quickly explode from a Category 1 hurricane to Category 4?
Last Wednesday night, August 23, Harvey was a tropical depression, but after just eight overnight hours it was forming a hurricane eye wall. “That’s remarkably fast,” Masters says. On Friday it rapidly ballooned from a Category 1 hurricane to Category 4. That is because it happened to pass over a region of extremely warm ocean water called an eddy. This spot of hot water was 1 to 2 degrees Fahrenheit warmer than the Gulf of Mexico around it, which itself was already 1 to 2 degrees F higher than average, reaching 85 or 86 degrees F in places. The hotter the water, the more energy it drives into a storm. Hurricane Katrina, which destroyed New Orleans in 2005, also mushroomed to Category 4 in a similar fashion because it, too, passed over a hot eddy in the Gulf. Read more ..

The Future of Biofuel Isn’t Corn—It’s Algae

August 16th 2017

algae

When they hear “biofuel,” people tend to assume you’re talking about corn. That makes sense, given that corn is anticipated to provide 80 percent of this year’s ethanol production — much more, say, than algae — until we consider a few numbers.

By all accounts, microalgae is less land-intensive than corn production, and although it can pull double duty, providing high-quality feed for fish farms, it doesn’t compete with food crops. Furthermore, even by by the largely pro-corn Renewable Fuel Association’s water-consumption standards, corn ethanol is a thirsty fuel: Drinking 2.8 gallons of water for every gallon of fuel refined, corn is often outclassed in efficiency by algae-based fuels.

Pigments made by beets may help boost resistance to disease and the nutrition value of crops.

Color in the plant kingdom is not merely a joy to the eye. Colored pigments attract pollinating insects, they protect plants against disease, they confer health benefits, and are used in the food and drug industries. A new study conducted at the Weizmann Institute of Science, published in the Proceedings of the National Academy of Sciences, USA, has now opened the way to numerous potential uses of betalains, the highly nutritious red-violet and yellow pigments known for their antioxidant properties and commonly used as food dyes.

Betalains are made by cactus fruit, flowers such as bougainvillea, and certain edible plants – most notably, beets. They are relatively rare in nature, compared to the two other major groups of plant pigments, and until recently, their synthesis in plants was poorly understood. Prof. Asaph Aharoni of Weizmann’s Department of Plant and Environmental Sciences and Dr. Guy Polturak, then a research student, along with other team members, used two betalain-producing plants – red beet (Beta vulgaris) and four o’clock flowers (Mirabilis jalapa) – in their analysis.

Iot Devices Becoming 'Cyberweapon Of Choice' For Attackers

August 14th 2017

Shadowy Computer User

A new report from cloud and security solution provider F5 Labs (Seattle, WA) examines how attackers have developed botnets - or "thingbots" - to target IoT devices.

IoT devices, says F5, have become "the cyberweapon delivery system of choice" for attackers building botnets - collections of Internet-connected devices that are infected and controlled by a common type of malware. Botnets can overwhelm systems with traffic with distributed denial-of-service (DDoS) attacks, steal data, send spam, and allow an attacker access to the device and its connection.

According to the latest report, IoT attack activity grew 280% from the prior six-month period. This included "massive growth" due to the Mirai malware - which turns networked devices running Linux into remotely controlled bots that can then be used as part of a botnet - and subsequent attacks.

Is Artificial Intelligence an Existential Threat?

August 6th 2017

Terminator Robot

It is not unusual for disrupting technologies to be embraced and feared—and not necessarily in that order. That was and will continue to be true for all technologies that bring both benefit and risk; it is a duality in which many technologies have to exist. Examples throughout history have been the airplane, the automobile, unmanned weapons systems, and now even software – especially the software which powers artificial intelligence (AI).

Last week at a U.S. governors’ conference, Elon Musk, the CEO of the engineering companies SpaceX and Tesla, reportedly told the assembled politicians that “AI is a fundamental existential risk for human civilization,” sounding the alarm bell. This is not the first time Musk has expressed this concern, he’s done so as early as 2014. Many have branded him a Cassandra, and if he is, he’s not a lone-wolf Cassandra; he’s joined in those views by the likes of Stephen Hawking, Bill Gates, and other experts. It is not surprising there is an equal number of experts who question Musk’s concern and believe his alarm bell is tolling for a non-existent threat.

Electric Vehicle Taps Solar to Recharge

July 31st 2017

Sunrise or Sunset

Startup company Sono Motors (Munich, Germany) has launched its debut feature: An electric vehicle that obtains its power not only through the grid, but also through solar cells integrated on its surface. Also, the Sion is up-to-date in terms of connectivity and IT-supported usage models.

The surface of the vehicle is covered with a total of 330 solar cells that are integrated into the roof, doors, the trunk lid and the front bonnet. Of course the energy these solar cells provide does not suffice to drive the four-seater completely, but as long as the car sees the sun they contribute to charging the batteries – according to the company they generate enough electricity to add some extra 30 kilometers per day.

The battery stores enough electricity for a 250 kilometer ride – not bad, given the competitive environment such as BMW’s i3 (maximum 160 km, and all that at a price tag of 30.000+ euros). The Sion, in contrast will cost 16.000 euros – and buyers have the choice to either buy the battery (for some 4000 euros) or rent it. Another unique feature of the electric system is that it can be used as power source, providing up to 2.7 kilowatts (DC) through the standard plug or up to 7.6 kW through an optional Type 2 connector. The bidirectionality of the electric system also enables the car to pump electricity back to the grid if required – a prerequisite to establish smart grids.

Ancient DNA Counters Biblical Story of Canaanites

July 28th 2017

Neanderthal and Human skulls

When the pharaohs ruled Egypt and the ancient Greeks built their first cities, a mysterious people called the Canaanites dominated the Near East. Around 4000 years ago, they built cities across the Levant, which includes present-day Lebanon, Israel, Jordan, and part of Syria. Yet the Canaanites left no surviving written records, leaving researchers to piece together their history from secondhand sources.

One of those sources is the Bible’s Old Testament, which documents a grisly end for the Canaanites: After the Israelites’ exodus from Egypt, they swept into Canaan and annihilated its people. But did that really happen? Archaeological data suggests that Canaanite cities were never destroyed or abandoned. Now, ancient DNA recovered from five Canaanite skeletons suggests that these people survived to contribute their genes to millions of people living today. Read more ..

What is Hyperloop?

Hyperloop is on track to be the next great transformation in mass transportation. The concept is simple: a network of on-demand, electrodynamically levitated pods traveling in evacuated tubes at 95% of the speed of sound. The term 'Hyperloop' was first coined in 2012 by technology billionaire and serial entrepreneur, Elon Musk. It is a radically new concept of point-to-point travel at speeds over 700mph, covering the distance between Edinburgh and London in 35 minutes.

How could Hyperloop influence the way that we travel in the future?

The implications of a Hyperloop corridor are immense; intercity commuting becomes comparable to taking the metro, injecting economic stimulus throughout the country and creating a superproductive population. Beyond connecting cities, Hyperloop has the potential to combine separate airports into terminals of an integrated airport network. Read more ..

LHC Physicists Unveil a Charming New Particle

July 8th 2017

CERN CMS Endcap

Physicists using the Large Hadron Collider beauty (LHCb) experiment at CERN in Geneva, Switzerland, have discovered a new kind of heavy particle, they announced this week at a conference in Venice.

The particle, known as Xi-cc++ (pronounced “Ksī-CC plus-plus”), is composed of three smaller elementary particles called quarks—specifically, one lighter-weight “up” quark like those found in protons and neutrons as well as two “charm” quarks, which are a heavier and more exotic variety. (The designations “up” and “charm” are two of the six “flavors” physicists assigned to quarks based on the particles’ varying masses and charges.) The Standard Model of particle physics predicts Xi-cc++ and many other possible particles with various configurations of the six known flavors of quarks.

But until now such “doubly charmed” particles had eluded conclusive detection. Further studies of the new particle—and other members of the doubly charmed particle family—could reinforce the Standard Model or lead to new vistas in particle physics. Either way, the new particle could be a tool to unlock a deeper understanding of the fundamental “strong” force that binds quarks together to form protons and neutrons, which in turn form atoms—as well as planets, stars, galaxies and people.

Originally filed in late 2015, the patent application describes the concept as a "multi-level fulfillment center designed to accommodate landing and takeoff of unmanned aerial vehicles (UAVs)." In addition, unlike conventional fulfillment warehouses - which are typically located outside of cities where space is available - the new fulfillment center concept is designed to be located in an urban setting, "such as in a densely populated area," allowing quicker delivery.

The new concept is not intended as drone only. The application indicates that it could also support traditional deliveries, including by ground vehicles, as well as self service pick-up.

Externally, the tower concept may include "apertures" - of many possible shapes - to allow authorized UAVs to enter and exit the center. However, the centers would be designed to blend in with other high-rise buildings in the area.

Amazon completed its first successful delivery by drone last December in a small town located near Cambridge, England. According to the company, the "Prime Air" delivery was accomplished in 13 minutes "from click to delivery."

Scientists Suggest Light Momentum Carried By Atomic Shock Wave

July 5th 2017

Nagasaki_Bomb

Finnish scientists have shed some light on 100 year-old paradox that there have been two different values for the momentum of light in a transparent medium and that typically, these values differ by a factor of ten.

The paradox that light has momentum but does not have mass is another matter.

Researchers from Aalto University have published a paper in Physics Review A that claims to show that the propagation of light in a transparent medium is associated with the transfer of atomic mass density. The passage of the photon through the medium sets the atoms in motion and a propagation wave of those atoms carries a significant part of the total momentum of the light. In the case of silicon this atomic wave carries 92 percent of the total momentum of light.

To solve the momentum paradox the paper's authors show that the special theory of relativity requires an additional atomic density wave or shock wave to travel with the photon. The total momentum of light is split into two components. The photonic share of momentum is equal to the Abraham momentum while the total momentum, which also includes the momentum of atoms driven forward by the optical force, is equal to the Minkowski momentum.

An explanatory video can be seen here:

"Since our work is theoretical and computational it must be still verified experimentally, before it can become a standard model of light in a transparent medium," said researcher Mikko Partanen, in a statement. "This should be feasible using present interferometric and microscopic techniques and common photonic materials," he added.

The researchers are working on potential optomechanical applications enabled by the optical shock wave of atoms predicted by the new theory. However, the theory applies not only to transparent liquids and solids but also to dilute interstellar gas. Thus, if verified the theory could have implications for astronomy and cosmology

Researchers at the Korea Advanced Institute of Science and Technology (KAIST) have developed a Convolutional Neural Network Processor on silicon that they combined with a custom made image sensor to perform face recognition with a 97% accuracy while only drawing 0.62mW.

Using such embedded artificial intelligence, the researchers claim their solution consumed only 1/5000 the power that would be required by a GPU performing the same tasks.

This unique processor owes its incredibly low power consumption thanks to its CNN whose circuitry, architecture, and algorithms have all gone through optimization steps. On-chip memory has been integrated in the CNNP so it could be read in a vertical direction as well as in a horizontal direction, reports KAIST.

In the CNNP, 1024 multipliers and accumulators operate in parallel and the chip is capable of directly transferring the temporal results to any of those without access to external memory or to an on-chip communication network.

With the amount of software in today’s cars in the dimension of millions of lines of code, updating vehicle software today is a cumbersome business. Now Continental has created the necessary technology and infrastructure to enable secure software updates over the air, doing away with the need to visit the garage for every update.

With significance for software for the user experience of car buyers updates having dramatically increased over the past decade or so, automotive manufacturers are feverishly working on solutions to establish similar mechanisms for their vehicles. So far, only Tesla dares to update the software of its cars automatically. All others look jealously over the fence, frightened by the prospect of a terrible glitch or, even worse, a cyber attack against the transmission path. Also, updating a vehicle’s software is somewhat more complex than updating a smartphone’s operating system: Up to 100 computers are involved, and since they are all connected, the activities of most of them can have side effects on others. Plus, the number of possible variants and options in a car is much bigger than in a smartphone. And last but not least, no one can afford a failed software update – in a car such a situation would have far more serious consequences than with a smartphone.

Man cupping his ear

Led by Nelson Sepúlveda, Associate Professor at the Michigan State University, a team of researchers who recently reported a breakthrough in ferroelectret nanogenerators (FENGs) was able to further characterize the behaviour of their thin-film FENG as a flexible acoustic transducer capable of operating both as a loudspeaker and a microphone.

Their paper "Nanogenerator-based dual-functional and self-powered thin patch loudspeaker or microphone for flexible electronics" published in Nature Communications examines the FENG's energy conversion mechanism under various sound pressure levels (SPL). Because the 0.1mm thin polypropylene ferroelectret (PPFE) includes compressible charged voids behaving as deformable dipoles in a metal-insulator-metal structure (with conductive silver layers for electrodes on the faces of the film), the alternating waves of sound pressure are faithfully transduced into alternating electrical signals. Here, rather than focus on energy generation, the study focused on reading out the analogue signal produced by the polymer-based FENG and the results are compelling.

Separator Layer Can Make Lithium-ion Batteries Fireproof

April 15th 2017

Lithium-ion batteries, though being considered as the power source of choice for today’s electric vehicles, are having a significant disadvantage: They are not fireproof. Even worse, they tend to catch fire under overload and short circuit conditions which can occur as a consequence of accidents. Researchers from the Stanford University have developed a potential solution.

The reason why lithium ion batteries can start burning so easily is that the electrolytes necessary to enable the exchange of electrons between cathode and anode are flammable and highly reactive. Though battery manufacturers have tried to minimize this risk through internal protective covers or by adding flame retardants, the risk persists, acknowledged Stanford researcher Kai Liu. In addition, these measures have side effects: They reduce the energy density and ion mobility which in turns reduces the battery performances.

Smartphone Fingerprint Security Vulnerable

April 13th 2017

Smart phone

No two people are believed to have identical fingerprints, but researchers at the New York University Tandon School of Engineering and Michigan State University College of Engineering have found that partial similarities between prints are common enough that the fingerprint-based security systems used in mobile phones and other electronic devices can be more vulnerable than previously thought.

The vulnerability lies in the fact that fingerprint-based authentication systems feature small sensors that do not capture a user's full fingerprint. Instead, they scan and store partial fingerprints, and many phones allow users to enroll several different fingers in their authentication system.

Identity is confirmed when a user's fingerprint matches any one of the saved partial prints. The researchers hypothesized that there could be enough similarities among different people's partial prints that one could create a "MasterPrint."

Nasir Memon, a professor of computer science and engineering at NYU Tandon and the research team leader, explained that the MasterPrint concept bears some similarity to a hacker who attempts to crack a PIN-based system using a commonly adopted password such as 1234. "About four percent of the time, the password 1234 will be correct, which is a relatively high probability when you're just guessing."

An international team of researchers from the University of California, San Diego and the Australia-based Commonwealth Scientific and Industrial Research Organisation (CSIRO) have devised a disposable 'lab-on-a-glove' enabling the wearer to identify health-threatening biochemical agents through a simple and secure swipe across a surface to be tested.

The researchers used tailor-made printable inks stencil-printed as serpentine patterns on regular purple nitrile powder-free exam gloves to create stretchable, yet robust conductive circuits. The thumb is used as a sample collection surface and only sports a printed stretchable carbon disk to ensure the adhesion of analyte residues.

At the tip of the index, part of an electrochemical cell is printed, immobilizing the enzyme organophosphorus hydrolase (OPH) capped with a conductive semi-solid gel matrix (covering an enzymatic OPH/Nafion layer) for analyte diffusion from the collection pad towards the OPH enzyme layer on the working electrode. The enzyme reacts to the presence of organophosphate (OP) compounds, also known as nerve agents for their high neurotoxicity.

Easily-tricked Microprocessors are Security Threat

March 27th 2017

Trendy Kitchen

Microprocessors have had numerous layers of software protection wrapped around them to improve security as well as hardware support provided for the encryption of keys for encoding and keeping secret data and communications. However, this is effort primarily addressed the threat of hacking over wired or wireless communications channels. Little or no thought has been given to the data that comes from local sensors, which has just been assumed to be valid.

The rapid growth of the market for embedded systems and the Internet of Things and the broad deployment of sensors means a traditional lack of security around sensors has become a security problem, the university research team asserts. Read more ..

Science Sting Exposes Corrupt Journal Publishers

March 23rd 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.

The Race for EVs

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.

Molecular 'Leaf' Harvests Sunlight Without Solar Cells

March 13th 2017

graphene

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.

Scientific Breakthroughs in 2017 May "Blow Your Mind"

January 11th 2017

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?

January 2nd 2017

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.
