Technology that can convert salty seawater or brackish water into safe, clean drinking water has the potential to transform millions of lives across the globe, which is why so many scientists are busy working on projects to do just that.

Now, a new innovation developed by scientists in Australia could be the most promising one yet, with researchers using metal-organic framework compounds (or MOFs) together with sunlight to purify water in just half an hour, using a process that’s more efficient than existing techniques.

It’s cheap, it’s stable, it’s reusable, and it produces water that meets the World Health Organisation (WHO) standards for desalination. Around 139.5 litres (nearly 37 gallons) of clean water can be produced per day from a kilogram (2.2 pounds) of MOF material, based on early testing.

A recent column in The Atlantic magazine, “The Most Overhyped Planet in the Galaxy” implored the research community to expand its robotic exploration horizons beyond Mars. But despite arguments for rethinking what the article’s author, Marina Koren, terms the U.S.’ scientific “Mars monopoly” in favor of some of our solar system’s less-visited outer moons, scientific understanding of the Red Planet is arguably still decades away.

Rest assured, Mars should and will remain a scientific Valhalla for decades to come.

The researchers fused machine learning from demonstration algorithms and more classical autonomous navigation systems. Rather than replacing a classical system altogether, APPLD learns how to tune the existing system to behave more like the human demonstration. This paradigm allows for the deployed system to retain all the benefits of classical navigation systems—such as optimality, explainability and safety—while also allowing the system to be flexible and adaptable to new environments, Warnell said.

In the future, a soldier and a game controller may be all that’s needed to teach robots how to outdrive humans.

At the U.S. Army Combat Capabilities Development Command’s Army Research Laboratory and the University of Texas at Austin, researchers designed an algorithm that allows an autonomous ground vehicle to improve its existing navigation systems by watching a human drive. The team tested its approach—called adaptive planner parameter learning from demonstration, or APPLD—on one of the Army’s experimental autonomous ground vehicles.

All kinds of fascinating discoveries are likely lying in wait for us in the deep sea. Now scientists have pulled a new monster out of the waters off the coast of Indonesia. The creature is a new species of “supergiant” isopod, a huge marine relative of the common pillbug.

The discovery was made during the South Java Deep Sea Biodiversity Expedition 2018 (SJADES 2018). At depths between 950 and 1,260 m (3,115 and 4,135 ft), the team found two specimens of giant isopods that were soon determined to belong to a new species.

Named Bathynomus raksasa, the holotype, or physical specimen that serves as the basis for the description and name of the new species, is a male that was measured to be 36.3 cm (14.3 in) long, which puts it among the largest giant isopods ever found. The second specimen was a female measuring 29.8 cm (11.7 in). Along with being bigger on average, the team noted other differences when compared to the closest known species, Bathynomus giganteus, including smoother “skin” and different body proportions and shapes.

The 19 hospitalized patients from a single nursing home had tested positive for the virus in April.

All were older than age 64 and had chronic health conditions such as hypertension, dementia, heart disease, diabetes and lung diseases. Their age and health issues are considered risk factors for severe COVID-19.

The patients received either one or two intravenous doses of itolizumab along with the standard treatments used in Cuba at the time. Those included antiviral drugs, antibiotics, chloroquine, interferon, and blood thinners. Only two patients required oxygen therapy after the first dose, and all but one were discharged from the hospital in 14 days.

N”(Reuters) — An antibody drug already being used against the coronavirus in Cuba decreased the risk of intensive care admission and death among nursing home residents with moderate COVID-19, according to a small study conducted in the island nation.
