Conscious spending can unlock greener science - Chemical & Engineering News

A healthy, green lawn can be the envy of any neighborhood, but how does someone cultivate a yard like that? Assistant Professor of Ecosystem Science Amber Churchill has been getting her hands dirty and digging into the science behind it. Through the Pasture and Lawn Enhanced Diversity Global-change Experiment (PLEDGE), Churchill and her team discovered that lavish lawns depend on the environment: The number of species in an ecosystem affects how the system functions. The PLEDGE research initiative is located at Nuthatch Hollow, the outdoor laboratory and wildlife sanctuary gifted to the University by Robert F. Schumann and the Schumann family.

Even when artificial intelligence behaves exactly like a human, people are reluctant to consider it conscious, according to a new study from Ludwig Maximilian University of Munich (LMU). As artificial intelligence becomes more advanced, reports of AI systems misleading users, working together, or appearing to pursue independent goals are becoming increasingly common. These behaviors often lead people to describe AI as though it can think, feel, or make decisions for itself. But does behaving like a human actually convince people that a machine has consciousness?

Scientists have discovered that some cells can reorganize after an organism’s death into new “third state” forms called xenobots that exhibit unexpected behaviors. While some researchers argue that cells show decision-making or even consciousness, skeptics say there’s not enough evidence. Xenobots could help scientists understand cell organization and develop future health therapies. The biological cycle of our existence seems relatively straightforward: we’re born, we live, we die. The end. But when you examine existence at the cellular level, things get a bit more interesting. You, me, and all of the 108 billion or so Homo sapiens who’ve ever walked the Earth have all been our own constellation of some 30 trillion cells. Each of our bodies is a collective organism of living human cells and microbes working in cooperation to create what our minds view as “life.” However, a growing number of new studies have found that, at least for some cells, death isn’t the end. Instead, it’s possibly the beginning of something new and wholly unexpected.
