Singapore, 5 May 2021 - The rapid advancement of Autonomous Vehicles (AV) technology in recent years has changed transport systems and consumer habits globally. As countries worldwide see a surge in AV usage, the rise of shared Autonomous Mobility on Demand (AMoD) service is likely to be next on the cards. Public Transit (PT), a critical component of urban transportation, will inevitably be impacted by the upcoming influx of AMoD and the question remains unanswered on whether AMoD would co-exist with or threaten the PT system.

LOS ALAMOS, N.M., May 5, 2021 A massive collaborative research project covered in the journal
Nature this week offers projections to the year 2100 of future sea-level rise from all sources of land ice, offering the most complete projections created to date. This work synthesizes improvements over the last decade in climate models, ice sheet and glacier models, and estimates of future greenhouse gas emissions, said Stephen Price, one of the Los Alamos scientists on the project. More than 85 researchers from various disciplines, including our team at Los Alamos National Laboratory, produced sea-level rise projections based on the most recent computer models developed within the scientific community and updated scenarios of future greenhouse gas emissions, said Price.
The patent-pending NanoSpot.AI is performed on a spot of blood obtained through a finger prick, and individuals receive test results on their mobile phones. The test is estimated to be significantly less expensive to manufacture than other SARS-CoV-2 antibody tests, so it has the potential to be considerably more affordable than currently available tests, making it possible to extend the test to every corner of the world. Clinical studies validating NanoSpot.AI are currently underway.

Over the coming decades, our economy and society will need to dramatically reduce greenhouse gas emissions as called for in the Paris Agreement. But even a future low-carbon economy will emit some greenhouse gases, such as in the manufacture of cement, steel, in livestock and crop farming, and in the chemical and pharmaceutical industries. To meet climate targets, these emissions need to be offset. Doing so requires negative emissions technologies, by means of which CO2 is removed from the atmosphere and permanently stored in underground repositories.
Researchers at ETH Zurich have now calculated the potential of one of these technologies for Europe: the combination of energy extraction from biomass with the capture and storage of CO2, or bioenergy with carbon capture and storage (BECCS) as it is known. The calculations revealed that if BECCS were exploited to its full potential, it would reduce carbon emissions in Europe by 200 million tonnes per year. This represents 5
Researchers at C-Crete Technologies and Rice University have found the right ingredients for cement that does double duty as a structural material and a photocatalytic water purifier with a built-in means of replenishment: simply sand down the material s surface to refresh the photocatalytic quality.
