This unmanned agricultural robot could transform the industry

Posted by in categories: employment, food, robotics/AI

New Zealand-based agritech company Robotics Plus has launched an autonomous multi-use, modular vehicle for agriculture that could revolutionize the industry by alleviating ongoing labor shortages and simplifying agricultural tasks, according to a press release by the firm published on Thursday.

Optimizing tasks

The robot can be supervised in a fleet of vehicles by a single human operator, using a combination of vision systems and other technologies to sense its environment. This empowers it to optimize tasks and allow intelligent and targeted application of inputs such as sprays. It is suitable for a variety of jobs including spraying, weed control, mulching, mowing and crop analysis.

Hundred-Year-Old Shipwreck Emerges From River

Posted by in category: computing

The drought affecting the Mississippi River has revealed a watery secret – a shipwreck that’s over a hundred years old. The skeleton of the craft emerged in Baton Rouge this summer, thanks to low water levels. Dr. Chip McGimsey, archaeologist for the State of Louisiana, believes the ruins belong to the Brookhill Ferry, which sank in 1915. He says the wreck provides a unique way to explore the past, noting, “It makes history alive in a way that you don’t get any other way.”

France’s Nuclear Reactors Malfunction as Energy Crisis Bites

Posted by in categories: nuclear energy, security

PARIS—France is falling behind in its plans to return the country’s fleet of nuclear reactors to full power this winter after a rash of outages, raising fears that one of Europe’s key sources of electricity won’t be ramped up to counter Russia’s squeeze on the continent’s energy supplies.

The nuclear fleet was designed to act as the front line of France’s energy security. Since Moscow cut the flow of natural gas to Europe—plunging the continent into its biggest energy crisis since the 1970s oil shock—France’s vaunted nuclear fleet has been about as effective as the Maginot Line, the French fortifications that did little to stop the German invasion during World War II.

A New, Easier and Safer Way To Synthesize Medicines

Posted by in categories: biotech/medical, chemistry

Carbenes are among the most adaptable building blocks in organic chemistry, but they may also be dangerously hot. Due to their explosivity in the lab, scientists often avoid using these very reactive molecules.

However, in a new study that was just published in the journal Science, researchers from The Ohio State University describe a new, safer method to turn these short-lived, high-energy molecules into much more stable ones.

“Carbenes have an incredible amount of energy in them,” said David Nagib, co-author of the study and a professor of chemistry and biochemistry at Ohio State. “The value of that is they can do chemistry that you just cannot do any other way.”
