MIT's new cement recipe could cut carbon emissions by more than half

As one of our most relied upon construction materials, concrete makes a significant contribution to our overall carbon emissions. Calcium-based substances are heated at high temperatures to form the cement, a process that produces carbon dioxide. But by slightly altering the quantities of materials used, scientists from MIT have uncovered a new method of cement mixing that could reduce these emissions by more than half. Read More

MIT to test making oxygen on Mars

Oxygen is such an abundant resource on Earth that we rarely think about it unless we get locked in a cupboard. However, for space engineers, the question of how to get enough of the vital gas is constant, frustrating problem. To help future explorers of the Red Planet get enough oxygen for life support and powering spacecraft, NASA has included MIT’s MOXIE experiment on the Mars 2020 mission to study how to make oxygen out of the Martian atmosphere.

"Solar" jet fuel created from water and carbon dioxide

In a move that could help address our insatiable thirst for fuel while at the same time help cut CO2 emissions, scientists with the SOLAR-JET (Solar chemical reactor demonstration and Optimization for Long-term Availability of Renewable Jet fuel) project have recently shown that through a multi-step process, concentrated sunlight can be used to convert carbon dioxide into kerosene, which can then be used as jet fuel.

Breathing easy while sleeping could combat symptoms of altitude sickness

Headaches, nausea, weakness and dizziness, combined with a feeling that you just can’t get enough oxygen with each breath are just some of the signs of altitude sickness. Researchers have now found a link between the abnormal breathing patterns experienced while sleeping at altitude and the symptoms of altitude sickness, particularly headaches. The finding suggests that finding a way to breath normally while sleeping could provide a way to combat such symptoms. Read More

New Bosch system shuts off coasting cars' engines

Cars don't need to have their engines running when they're stopped at red lights. That's why a number of automakers have developed start-stop systems, which stop a car's engine when the vehicle comes to a halt, and start it again as soon as the gas pedal is pressed. Bosch, however, is taking things farther. Its new start-stop system shuts the engine off not only at stops, but also whenever the car is coasting. Read More

XPrize announces Ocean Health competition

Since 1995, XPrize has been promoting science and technology by setting “Grand Challenges” with cash incentive prizes. On Monday, the organization announced the launch of three new competitions by 2020 as part of its XPrize Ocean Initiative, which is aimed at improving the health and understanding of the world’s oceans.

Smart door seal keeps conference rooms from getting stuffy

If you’re in a confidential meeting with the boardroom door closed, the air can get stale pretty fast. Should it be too cold outside to crack any windows, or if the room simply has no windows, then opening those isn’t a choice. That’s why Germany’s Fraunhofer Institute for Microelectronic Circuits and Systems has teamed up with the Athmer Company to create an “intelligent door seal system.” Read More
