ClimateWire reporter John Fialka writes that MIT engineers have developed a new process to convert carbon dioxide into a powder that can be safely stored for decades. “The MIT process gets closer to an ambitious dream: turning captured CO2 into a feedstock for clean fuel that replaces conventional batteries and stores electricity for months or years,” writes Fialka. “That could fill gaps in the nation's power grids as they transition from fossil fuels to intermittent solar and wind energy.”

Prof. Jessika Trancik speaks with Boston Globe reporter Aruni Soni about her new study that finds reducing the cost of solar energy will be accelerated by improvements in soft tech. “We found that the soft technology involved in solar energy really has not changed and hasn’t improved nearly as quickly as the hardware,” says Trancik. “These soft costs, in many systems, can be 50 percent or even more of the total cost of solar electricity.”

NBC Boston’s Jeff Saperstone visits MIT to learn more about how researchers discovered that a common hydrogel used in cosmetic creams, industrial coatings and pharmaceutical capsules can absorb moisture from the atmosphere as the temperature rises. The material could one day be used to harvest moisture for drinking water or feeding crops. “For a planet that's getting hotter, this could be a game-changing discovery,” Saperstone notes.

MIT researchers devised a new way to arrange LED pixels to create screens with a much higher resolution than is currently possible, reports The Economist. The new technique, which involves stacking micro LEDS, could also be used to make “VR images that appear far more lifelike than today’s.”

Gizmodo reporter Isaac Schultz writes that researchers from MIT, Caltech and elsewhere have found that “quantum systems can imitate wormholes, theorized shortcuts in spacetime, in that the systems allow the instantaneous transit of information between remote locations.” Grad student Alexander Zlokapa explains that: “We performed a kind of quantum teleportation equivalent to a traversable wormhole in the gravity picture. To do this, we had to simplify the quantum system to the smallest example that preserves gravitational characteristics so we could implement it.”

Physics World has named two research advances by MIT researchers to its list of the Top 10 Breakthroughs of the Year. Prof. Gang Chen and his colleagues were selected for their work “showing that cubic boron arsenide is one of the best semiconductors known to science.” Prof. Asegun Henry, grad student Alina LaPotin and their colleagues were nominated for “constructing a thermophotovoltaic (TPV) cell with an efficiency of more than 40%.”

Physicists from MIT and elsewhere have created a small “wormhole” effect between two quantum systems on the same processor and were able to send a signal through it, reports Charlotte Hu for Popular Science. This new model is a “way to study the fundamental problems of the universe in a laboratory setting,” writes Hu. 

Researchers at MIT and elsewhere have created a holographic wormhole using Google’s Sycamore quantum computer, reports Sarah Wells for Vice. “The researchers created an entangled state (a quantum mechanical phenomena where distant particles can still communicate with each other) between two halves of a quantum computer and sent a message in between,” writes Wells. “This message was scrambled as it entered the system and, through entanglement, unscrambled on the other side.”

A team of researchers, including scientists from MIT, “simulated a pair of black holes in a quantum computer and sent a message between them through a shortcut in space-time called a wormhole,” reports Dennis Overbye for The New York Times. The development is another “step in the effort to understand the relation between gravity, which shapes the universe, and quantum mechanics, which governs the subatomic realm of particles,” writes Overbye.

Prof. Jessika Trancik speaks with Forbes contributor Peter Cohan about the carbon emissions associated with gas, hybrid and electric vehicles, and the site she and her research group developed to allow consumers to compare personal vehicles against climate change mitigation targets. “In most locations, compared to [gas-powered vehicles], EVs produce emissions savings greater than 30%,” says Trancik. "Most savings are greater depending on the geographic location, the electricity supply, and the vehicle model.”

Researchers at MIT have built a highly efficient thermophotovoltaic cell that converts incoming photons to electricity, reports Kevin Hurler for Gizmodo. “We developed this technology—thermal batteries—because storing energy as heat rather than storing it electrochemically is 10 to 100 times cheaper," explains Prof. Asegun Henry. 

A team of researchers from MIT and the National Renewable Energy Laboratory successfully reached a 30% jump in thermophotovoltaic (TPV) efficiency, reports Robert F. Service for Science. “[TPV] is a semiconductor structure that concerts photons emitted from a heat source to electricity, just as a solar cell transforms sunlight into power,” explains Service.

Daily Beast reporter Miriam Fauzia writes that MIT researchers have developed a new way to create carbon fibers that are stronger and lighter than steel, using leftover waste from crude oil processing. “The new findings could usher in an age of heavy-duty cars that consume less fuel thanks to their decreased weight,” writes Fauzia.

Hill reporters Saul Elbein and Sharon Udasin spotlight how MIT researchers have developed a way to make lightweight fibers for possible use in the bodies of cars out of the waste material from the refining of petroleum. “The ‘heavy, gloppy’ leftovers from the petroleum refining process could become a key ingredient in making electric vehicles lighter, less expensive and more efficient,” they write.

Popular Science reporter Shi En Kim spotlights how MIT scientists created a new plastic material with the strength of steel. “This substance could be used as protective coatings for metal surfaces, such as the finish on cars, or as filters for purifying water,” writes Kim.
