Recently published research by Nunes et al. in the journal Weed Science shows planting soybean into a green, living cover crop provides effective control for some of the nation’s most troublesome weeds when integrated with pre-emergence (PRE) herbicides. More specifically, planting soybean over a cereal rye cover crop demonstrates an effective practice to both produce soybean and to suppress two problematic Amaranthus weed species: waterhemp and Palmer amaranth.

Researchers used solar energy to convert CO2 into a valuable chemical commodity with a two-step solar-powered process. First, electricity from solar energy combined with electrochemistry converts CO2 to ethylene. The ethylene gas stream that exits this process then feeds directly to a thermal catalytic reactor that uses heat derived from the sun to convert ethylene to butene.

Attractive metal-metal bonding occurs in a variety of molecules made of metallic atoms such as Iridium (Ir). Current theoretical and experimental methods have shown the existence of two isomers for Ir-Ir molecular systems, but researchers have not been able to predict the proportions of these two isomers or how they interact. This research combines ultrafast experimental measurements and numerical simulations to tease out key information about the two isomers in Ir-Ir complexes.

Two forms of gallium oxide come together in a "phase heterojunction" to create a sensitive ultraviolet detector.

Imagine controlling apps with your feet while you walk. This concept is the focus of new research which explores using gait gestures – intentional variations in how you walk – as controls for augmented reality (AR) devices. 

The surface features of neutron stars are largely unknown. Nuclear theorists explored mountain building mechanisms active on the moons and planets in our solar system. Some of these mechanisms suggest that neutron stars are likely to have mountains. Neutron star mountains would be much more massive than any on Earth--so massive that gravity just from these mountains could produce ripples in the fabric of space and time.

Medical advancements have extended the lifespans of children and adolescents diagnosed with life-limiting conditions, resulting in a greater need for healthcare resources and expanded caregiver services. The Hong Kong Polytechnic University (PolyU) researchers have studied the physical and non-physical needs of patients, parents and healthcare providers to enhance the provision of holistic healthcare services.

Instabilities in the plasma in a tokamak device can cause disruptions that result in rapid loss of plasma confinement and the release of large amounts of energy. Current approaches can suppress one type of disruption, tearing instabilities, after they form. Here, researchers tested a method using AI/deep reinforcement learning that instead adjusts plasma conditions in real-time to avoid these instabilities from developing in the first place.
