The majority of commercial chemicals that enter the market in the United States every year have insufficient health and safety data. For pesticides, the U.S. Environmental Protection Agency uses a variety of techniques to fill data gaps in order to evaluate chemical hazard, exposure and risk. Nonetheless, public concern over the potential threat that these chemicals pose has grown in recent years, along with the realization that traditional animal-testing methods are not pragmatic by means of speed, economics or ethics. Now, researchers at the George Washington University have developed a new computational approach to rapidly screen pesticides for safety, performance and how long they will endure in the environment. Moreover, and most importantly, the new approach will aid in the design of next-generation molecules to develop safer pesticides.

“In many ways, our tool mimics computational drug discovery, in which vast libraries of chemical compounds are screened for their efficacy and then tweaked to make them even more potent against specific therapeutic targets,” Jakub Kostal, an assistant professor of chemistry at GW and principal investigator on the project, said. “Similarly, we use our systems-based approach to modify pesticides to make them less toxic and more degradable, while, at the same time, making sure they retain good performance. It’s a powerful tool for both industry and regulatory agencies that can help design new, safer analogs of existing commercial agrochemicals, and so protect human life, the environment and industry’s bottom line.”

Using their model, the team analyzed 700 pesticides from the EPA’s pesticide registry. The model considered a pesticide’s likely persistence or degradation in the environment over time, its safety, and how well it performed at killing, repelling or controlling the target problem.

Even before Russia invaded Ukraine, the fuel that runs the global economy was in short supply.

Now some analysts say there could be spot shortages of diesel fuel and prices may stay elevated, even if oil and gasoline decline.

Those higher diesel fuel prices are also stoking inflation.

On top of the environmental concerns, Japan has an added motivation for this push towards automation —its aging population and concurrent low birth rates mean its workforce is rapidly shrinking, and the implications for the country’s economy aren’t good.

Thus it behooves the Japanese to automate as many job functions as they can (and the rest of the world likely won’t be far behind, though they won’t have quite the same impetus). According to the Nippon Foundation, more than half of Japanese ship crew members are over the age of 50.

In partnership with Misui OSK Lines Ltd., the foundation recently completed two tests of autonomous ships. The first was a 313-foot container ship called the Mikage, which sailed 161 nautical miles from Tsuruga Port, north of Kyoto, to Sakai Port near Osaka. Upon reaching its destination port the ship was even able to steer itself into its designated bay, with drones dropping its mooring line.

With the onset of warmer temperatures, winter canola is breaking dormancy and army cutworms are now present in fields across Kansas. Significant army cutworm pressure has been observed in fields northwest of Caldwell in Sumner County.

Army cutworms feed aggressively and significant damage can occur in a short period of time. Smaller plants are most susceptible. The larvae feed on the leaf tissue, leaving the plants with a fed-on appearance (Figure 2). When minor feeding is observed, you may find leaves severed from the plant and laying on the soil surface. Where infestations are high, army cutworms will remove all leaf tissue, leaving only the base of the stem (Figure 3).

The economic threshold for chemical control is 1–2 cutworms per foot of row. Army cutworms behave nocturnally and typically spend the daylight hours below ground. When scouting, it is critical to dig in the soil around individual canola plants to find the larvae. However, it is not unusual to find army cutworm above ground when populations are high (Figure 1). The larvae are greenish-gray and often curl up into a C-shape.

The installations of photovoltaic (PV) solar modules are growing extremely fast. As a result of the increase, the volume of discarded solar modules that end up on the recycling market annually will grow at the same rate in the near future. Currently, the aluminum, glass, and copper of the discarded modules are reprocessed; however, the silicon solar cells are not.

Now, researchers from the Fraunhofer Center for Silicon Photovoltaics CSP and the Fraunhofer Institute for Solar Energy Systems ISE, together with the largest German recycling company for PV modules, Reiling GmbH & Co. KG, have built new PERC solar cells with 100% crystalline silicon recycled from end-of-life photovoltaic panels.

The team has developed a process for recovering the silicon material with funding from the German Federal Ministry for Economic Affairs and Climate BMWK. The technique is claimed to recycle silicon from different types of crystalline silicon PV modules, regardless of manufacturer and origin.

If we are to set up a permanent base on the Moon, we will need some solid connection.

A space startup company is trying to make that happen. Aquarian Space recently announced receiving $650,000 in seed funding to develop a possible broadband internet connection that would link the Earth to the Moon, and maybe even Mars.

The company aims to deploy its first communications system to the Moon by 2024 in anticipation of increased demand from planned space missions to the Moon and beyond, both public and private ventures.

Decentralizing talent

More than 50 million creators are driving their own economy of talent, attracting in excess of $800 million in venture capital. Such figures are but a shadow of what they can become later, as new venues are rapidly becoming available.

The development of blockchain technologies has resulted in a sweeping revolution across financial markets, empowering individuals instead of institutions and channeling ownership of data and funds to their holders. The qualities of the blockchain — immutability, full transparency and the trustless nature of operations — have permeated many industries, swooning the balance of business orientation from centralized corporate reliance to decentralization. This shift in the basic concepts that govern relations between participants to transactions, facilitated by smart contracts, has not gone unnoticed in the creator economy.

Developments in artificial intelligence and human enhancement technologies have the potential to remake American society in the coming decades. A new Pew Research Center survey finds that Americans see promise in the ways these technologies could improve daily life and human abilities. Yet public views are also defined by the context of how these technologies would be used, what constraints would be in place and who would stand to benefit – or lose – if these advances become widespread.

Fundamentally, caution runs through public views of artificial intelligence (AI) and human enhancement applications, often centered around concerns about autonomy, unintended consequences and the amount of change these developments might mean for humans and society. People think economic disparities might worsen as some advances emerge and that technologies, like facial recognition software, could lead to more surveillance of Black or Hispanic Americans.

This survey looks at a broad arc of scientific and technological developments – some in use now, some still emerging. It concentrates on public views about six developments that are widely discussed among futurists, ethicists and policy advocates. Three are part of the burgeoning array of AI applications: the use of facial recognition technology by police, the use of algorithms by social media companies to find false information on their sites and the development of driverless passenger vehicles.

Engineers at the University of Cincinnati have developed a promising electrochemical system to convert emissions from chemical and power plants into useful products while addressing climate change.

UC College of Engineering and Applied Science assistant professor Jingjie Wu and his students used a two-step cascade reaction to convert carbon dioxide to carbon monoxide and then into ethylene, a chemical used in everything from food packaging to tires.

“The world is in a transition to a low-carbon economy. Carbon dioxide is primarily emitted from energy and chemical industries. We convert carbon dioxide into ethylene to reduce the carbon footprint.” Wu said. “The research idea is inspired by the basic principle of the plug flow reactor. We borrowed the reactor design principle in our segmented electrodes design for the two-stage conversion.”
