Cards Against Humanity, the comedy card game, has announced that applications are now being accepted for their Science Ambassador Scholarship. The scholarship is geared to award full-tuition to young women seeking undergraduate degrees in STEM.

This year, one winner will be selected by a board of sixty women in STEM to receive full tuition coverage for up to four years.

“I’m so excited that we’re able to offer another scholarship for a woman studying STEM. A lot of us at Cards Against Humanity have backgrounds in science and tech, and the under-representation of women in these fields is staggering,” says Jenn Bane, the Cards Against Humanity community director. “Ask a kid to draw a scientist, they’ll draw a man in a lab coat, because science and math are historically male-dominated fields. Cards Against Humanity has a large audience, so with the Science Ambassador Scholarship we hope to help change the public perception of what a scientist looks like.”

To apply, applicants must submit a three-minute video explaining a scientific topic they’re passionate about. Find more details here.

PS: If you want to contribute to the fund, you can pick up the Science Pack to add to your Cards Against Humanity Deck. All profits go to the Science Ambassador Scholarship.

Lithium-air batteries are viewed by many as a potential next-generation technology in energy storage. With the highest theoretical energy density of all battery devices, Li-air could revolutionize everything from electric vehicles to large-scale grid storage. However, the relatively young technology has a few barriers to overcome before it can be applied. A new study published in the Journal of The Electrochemical Society (JES) is taking a fundamental step forward in advancing Li-air through the development of mixed metal catalyst that could lead to more efficient electrode reactions in the battery.

The paper, entitled “In Situ Formed Layered-Layered Metal Oxide as Bifunctional Catalyst for Li-Air Batteries,” details a cathode catalyst composed of three transition metals (manganese, nickel, and cobalt), which can create the right oxidation state during the battery cycling to enable both the catalysis of the charge and the discharge reaction.

Future opportunities

According to K.M. Abraham, co-author of the paper, the manganese allows for the catalysis of the oxygen reduction reaction while the cobalt catalyzes the charge reaction of the battery.

“This offers opportunities for future research to develop similar materials to optimize the catalysis of the Li-air battery using one material that will combine the functions of these mixed metal oxides,” Abraham says.

Researchers from New York University have developed a new technique to give a highly detailed, 3D look inside a lithium-ion battery.

“One particular challenge we wanted to solve was to make the measurements 3D and sufficiently fast, so that they could be done during the battery charging cycle,” explains Alexej Jerschow, co-author of the study that details the development. “This was made possible by using intrinsic amplification processes, which allow one to measure small features within the cell to diagnose common battery failure mechanisms. We believe these methods could become important techniques for the development of better batteries.”

The look that the researchers offer gives new insight to dendrites – the deposits that build up inside a Li-ion battery that can affect performance and safety. To do this, the team used MRI technology to focus the image and took an additional step to improve image quality.

Corrosion costs the U.S. economy over $450 billion per year. In an effort to better predict the effects of corrosion, ECS Fellow Robert Kelly has built something akin to a time machine at the University of Virginia.

Kelly, who has recently been awarded ECS’s Corrosion Division H. H. Uhlig Award, is launching pieces of metal into the future to accelerate corrosion rates and observe how they will degrade over time. Being able to see the degradation of materials prior to application could be key to drastically cutting funds used to repair infrastructure when corrosion takes its toll.

Recently, Kelly applied his testing technique to Rolls-Royce’s small jet engine compressor blades to see how they would inevitably hold up in an airplane turbine. By aggressively spraying salt on the parts, Kelly could effectively predict how it will react when jet engines take in salt water in the form of sea salt aerosols. Rolls-Royce currently coats the blades with ceramic material – which if used in too small a quantity could lead to corrosion, but if used in too excessive a quantity could lead to slow, heavy blades. The tests conducted by Kelly and his team could help the company create a blade with the perfect balance of ceramic coating.

Artificial photosynthesis has carved out a promising corner in renewable energy research in recent history. This novel process is solar-driven, harvesting renewable energy and storing in in chemical bonds. Breakthroughs in artificial photosynthesis could lead to the development of solar fuels that could potentially shift the energy infrastructure.

However, while many technological barriers have been surpassed in the advancement of artificial photosynthesis, there are still hurdles to overcome. However, a research team from Forschungszentrum Juelich believes they may have just taken a significant step forward in the advancement of this field.

In a recently published paper, the team of scientists state that they have developed the first complete and compact design for an artificial photosynthesis facility.

The artificial photosynthesis process was first investigated in the 1970s. In fact, ECS Fellow Allen J. Bard can be seen here discussing the process in 1983. But only recently has artificial photosynthesis began to garner larger amounts of attention from the scientific community as a whole.

Each morning seems to bring new reports of hacks, privacy breaches, threats to national defense or our critical infrastructure and even shutdowns of hospitals. As the attacks become more sophisticated and more frequently perpetrated by nation-states and criminal syndicates, the shortage of defenders only grows more serious: By 2020, the cyber security industry will need 1.5 million more workers than will be qualified for jobs.

In 2003, I founded Cyber Security Awareness Week (CSAW) with a group of students, with the simple goal of attracting more engineering students to our cyber security lab. We designed competitions allowing students to participate in real-world situations that tested both their knowledge and their ability to improvise and design new solutions for security problems. In the past decade-plus, our effort has enjoyed growing interest from educators, students, companies and governments, and shows a way to closing the coming cyber security workforce shortage.

Today, with as many as 20,000 students from around the globe participating, CSAW is the largest student-run cyber security event in the world. Recruiters from the U.S. Department of Homeland Security and many large corporations observe and judge each competition. (Registration for this year’s competition is still open for a little while.)

The death of a person earlier this year while driving with Autopilot in a Tesla sedan, along with news of more crashes involving Teslas operating in Autopilot, has triggered a torrent of concerns about the safety of self-driving cars.

But there is a way to improve safety across a rapidly evolving range of advanced mobility technologies and vehicles – from semi-autonomous driver assist features like Tesla’s Autopilot to a fully autonomous self-driving car like Google’s.

The answer is connectivity: wireless communication that connects vehicles to each other, to the surrounding infrastructure, even to bicyclists and pedestrians. While connectivity and automation each provide benefits on their own, combining them promises to transform the movement of people and goods more than either could alone, and to do so safely. The U.S. Department of Transportation may propose requiring all new cars to have vehicle-to-vehicle communication, known as V2V, as early as this fall.

Tesla blamed the fatal crash on the failure of both its Autopilot technology and the driver to see the white tractor-trailer against a bright sky. But the crash – and the death – might have been avoided entirely if the Tesla and the tractor-trailer it hit had been able to talk to each other.

Limitations of vehicles that are not connected

Autonomous vehicles that aren’t connected to each other is a bit like gathering together the smartest people in the world but not letting them talk to each other. Connectivity enables smart decisions by individual drivers, by self-driving vehicles and at every level of automation in between.

Despite all the safety advances in recent decades, there are still more than 30,000 traffic deaths every year in the United States, and the number may be on the rise. After years of steady declines, fatalities rose 7.2 percent in 2015 to 35,092, up from 32,744 in 2014, representing the largest percentage increase in nearly 50 years, according to the U.S. DOT.

MXene is a nanomaterial that can super effectively block and absorb electromagnetic radiation.

We’ve all experienced electromagnetic interference, whether it’s hearing your car engine break in your AM radio station or the squealing of speakers at a concert when a cellphone gets to close. However, researchers from Drexel University may have found a way to all but stop this interference though what they’re calling MXene (2D Transition Metal Carbides).

Electromagnetic interference isn’t just annoying for users, it’s damaging for devices and could lead to the overall degradation of cellphones, laptops, and other electronics.

Typically, to block this interference, scientists encase the interior of electronics with conductive metal (i.e. metal, copper, or aluminum). But researchers for this new study found that a few-atoms thin titanium carbide may be more effective at blocking such interference. Additionally, it is extremely easy to apply – with the ability to be sprayed on to any surface just like paint.

“With technology advancing so fast, we expect smart devices to have more capabilities and become smaller every day. This means packing more electronic parts in one device and more devices surrounding us,” says ECS Fellow Yury Gogotsi, lead author of the research. “To have all these electronic components working without interfering with each other, we need shields that are thin, light and easy to apply to devices of different shapes and sizes. We believe MXenes are going to be the next generation of shielding materials for portable, flexible and wearable electronics.”

One year ago Tesla Motors announced plans to build its Gigafactory to produce huge numbers of batteries, giving life to the old saying, “if you want something done right, do it yourself.”

By making electric car batteries that Tesla used to buy from others, CEO Elon Musk adopted a strategy made famous by Henry Ford – build a vertically integrated company that controls the many stages of production. By integrating “backward” into its supply chain, Musk is betting Tesla can improve the performance and lower the costs of batteries for its vehicles.

Now, Musk wants Tesla to acquire SolarCity for similar reasons, but with a slightly different twist.

SolarCity is one of the largest installers of solar photovoltaic panels, with some 300,000 residential, commercial and industrial customers in 27 states. The proposed merger with SolarCity would vertically integrate Tesla forward, as opposed to backward, into the supply chain. That is, when people come to Tesla stores to buy a vehicle, they will be able to arrange installation of solar panels – and potentially home batteries – at the same time.

This latest move would bring Tesla one step closer to being the fully integrated provider of sustainable energy solutions for the masses that Elon Musk envisions. But does it make business sense?

The real issue in my mind comes down to batteries and innovation.

Creating demand and scale

Although installing batteries is not a big part of SolarCity’s current business, the company is a potentially large consumer of Tesla’s batteries from the Gigafactory. Tesla makes Powerwall batteries for homes and larger Powerpack systems for commercial and industrial customers.

Any increase in the flow of batteries through the factory gives Tesla better economies of scale and potential for innovation. Innovation comes with the accumulated experience gained from building a key component of its electric vehicles as well as Tesla’s energy storage systems. As the company manufactures more batteries, it will find ways to innovate around battery design and production.
