Rural communities are often built on agriculture and livestock. That means they’re also dependent upon a strong irrigation system – a potential weakness as the global water crisis grows. To more efficiently manage and coordinate the use of a scarce water supply in agricultural communities, a team from the Polytechnic University of Madrid proposed a blockchain-based automatic water control system.

“We investigated how blockchain technologies can be used to solve the problem of user competition for scarce resources in communities,” said Borja Bordel, the project’s lead investigator. “We particularize the problem to the irrigation communities, where independent users must trust a system that automates a fair and trustworthy distribution of the available water resources, according to an individual quota set by the community and the consumption forecasts of its users.”

Rules are paramount for the proposed system and must be established upfront by the community of users. In a prosumer environment, users establish regulations for their individual and community water quotas. Those regulations are then taken by a transformation engine and are built, compiled, and deployed. A simple infrastructure of common valves and pumps are complemented by interactive electronic devices and allow a SmartContract to oversee decision-making and control algorithms, as well as the state of the water sources.

Houston Mechatronics (HMI) unveiled Aquanaut at the NASA Neutral Buoyancy Laboratory, one year after the announcement of the platform concept.

Aquanaut is a revolutionary multi-mode transforming all-electric undersea vehicle. The vehicle is capable of efficient long-distance transit and data collection in ‘AUV’ (autonomous underwater vehicle) mode.

After transforming into ‘ROV’ (remotely operated vehicle) mode the head of the vehicle pitches up, the hull separates, and two arms are activated so that Aquanaut may manipulate its environment.

Bots built by artificial intelligence lab OpenAI worked together to find solutions to problems that humans hadn’t thought of.

Over the past few years, thermoelectric generators have become the focus of a growing number of studies, due to their ability to convert waste heat into electrical energy. Quantum dots, semiconductor crystals with distinctive conductive properties, could be good candidates for thermoelectric generation, as their discrete resonant levels provide excellent energy filters.

In a recent study, researchers at the University of Cambridge, in collaboration with colleagues in Madrid, Rochester, Duisburg and Sheffield, have experimentally demonstrated the potential of an autonomous nanoscale energy harvester based on resonant tunneling quantum dots. This harvester is based on previous research carried out by part of their team, who had proposed a three-terminal energy harvester based on two resonant-tunneling quantum dots with different energy levels.

The energy harvester device was realized at Cavendish Laboratory in Cambridge by a researcher called Gulzat Jaliel. The original theoretical proposal for the device, however, was introduced by Andrew Jordan in 2013, and the theoretical work behind the harvester was carried out by him in collaboration with renowned semiconductor physicist Markus Büttiker and a team of post-doctoral students in Geneva.

An outbreak could easily spread around the globe in 36 hours, sickening millions and costing $3 trillion. Epidemiologists say we’re not prepared.

The world is unprepared for a global pandemic that could wipe out 80 million people in less than 36 hours along with 5% of the global GDP, a new report from the WHO says.

If you can’t get to Mars, what’s the next best thing? Apparently Iceland. A team of renowned explorers and researchers recently journeyed to Iceland to test a Mars analog suit in a Martian-like environment.

The United sponsored expedition, led by The Explorers Club — an internationally recognized organization that promotes the scientific exploration of land, sea, air and space — and in partnership with Iceland Space Agency, involved the team venturing inside the Grímsvötn volcano and across the Vatnajökull ice cap. The group traveled to the remote location and lived for six days in the Grímsvötn Mountain Huts and endured harsh weather conditions and unstable terrain.
