Tumblr for a new user on iOS I have…

We’re currently rolling out an opt-in beta for a new post editor on web which will leverage the Neue Post Format behind the scenes. It’s been a very long time coming – work on the Neue Post Format began in 2015 and was originally codenamed “Poster Child”, and it was borne out of a lot of things we learned dealing with the previous new post editor we released on web around that time. Over the years, the landscape of how…

Engineers apply physics-informed machine learning to solar cell production

Despite the recent advances in the power conversion efficiency of organic solar cells, insights into the processing-driven thermo-mechanical stability of bulk heterojunction active layers are helping to advance the field. Credit: Department of Mechanical Engineering and Mechanics/Lehigh University Today, solar energy provides 2% of U.S. power. However, by 2050, renewables are predicted to be the most used energy source (surpassing petroleum and other liquids, natural gas, and coal) and solar will overtake wind as the leading source of renewable power.…

Beyond synthetic biology, synthetic ecology boosts health by engineering the environment — ScienceDaily

There’s a lot of interest right now in how different microbiomes — like the one made up of all the bacteria in our guts — could be harnessed to boost human health and cure disease. But Daniel Segrè has set his sights on a much more ambitious vision for how the microbiome could be manipulated for good: “To help sustain our planet, not just our own health.” Segrè, director of the Boston University Microbiome Initiative, says he and other scientists…

Arctic sea ice thinning faster than expected — ScienceDaily

Sea ice in the coastal regions of the Arctic may be thinning up to twice as fast as previously thought, according to a new modelling study led by UCL researchers. Sea ice thickness is inferred by measuring the height of the ice above the water, and this measurement is distorted by snow weighing the ice floe down. Scientists adjust for this using a map of snow depth in the Arctic that is decades out of date and does not account…

Underwater robot does not need help on the ocean floor

Credit: Delft University of Technology Robots can perform jobs underwater that are too complex or dangerous for humans. That is, if they can manage on their own, because no one can help them down there. The REMARO project works on its control systems and trains Ph.D. students in programming work. Robotic technology can be very useful for the maintenance of ships and infrastructure located in the water. The help of robots is also a godsend in combating oil spills in…

Rubisco proton production can enhance CO2 acquisition — ScienceDaily

Rubisco is arguably the most abundant — and most important — protein on Earth. This enzyme drives photosynthesis, the process that plants use to convert sunlight into energy to fuel crop growth and yield. Rubisco’s role is to capture and fix carbon dioxide (CO2) into sugar that fuels the plant’s activities. However, as much as Rubisco benefits plant growth, it also can operate at a notoriously slow pace that creates a hindrance to photosynthetic efficiency. About 20 percent of the…

The model can better predict the physical phenomenon inside of very-high-temperature pebble-bed reactors — ScienceDaily

When one of the largest modern earthquakes struck Japan on March 11, 2011, the nuclear reactors at Fukushima-Daiichi automatically shut down, as designed. The emergency systems, which would have helped maintain the necessary cooling of the core, were destroyed by the subsequent tsunami. Because the reactor could no longer cool itself, the core overheated, resulting in a severe nuclear meltdown, the likes of which haven’t been seen since the Chernobyl disaster in 1986. Since then, reactors have improved exponentially in…

Best ways to cut carbon emissions from the cement industry explored

Credit: Imperial College London A new Imperial report identifies alternative materials and carbon capture technologies as critical in decarbonising the cement industry. Around 3.5 billion tons of Ordinary Portland Cement, a critical building material worldwide, are produced annually—but every ton emits up to 622 kg of carbon dioxide (CO2) The cement industry contributes seven percent of global anthropogenic CO2 emissions, with the amount of CO2 released depending on differences in the materials used in production, the types of cement kiln…

Ancient horse DNA reveals gene flow between Eurasian and North American horses — ScienceDaily

A new study of ancient DNA from horse fossils found in North America and Eurasia shows that horse populations on the two continents remained connected through the Bering Land Bridge, moving back and forth and interbreeding multiple times over hundreds of thousands of years. The new findings demonstrate the genetic continuity between the horses that died out in North America at the end of the last ice age and the horses that were eventually domesticated in Eurasia and later reintroduced…
