Engineers from RMIT University have produced a new type of 3D-printed titanium that’s about a third cheaper than commonly used titanium alloys.

Humanity has an insatiable appetite for ammonia: this substance is used to make fertilizer, which in turn is used in most modern agriculture. Until now, the Haber-Bosch process has been the method of choice for extracting nitrogen from the seemingly inexhaustible atmosphere and binding it in the form of ammonia. However, this method requires an extremely large amount of methane gas and energy. Prof. Nikolay Kornienko from the University of Bonn has discovered a more climate-friendly alternative for producing ammonia from renewable energy sources. The research team is now presenting its findings in the journal Nature Communications. 

University Startup Entrepreneurs (USEs) possess the scientific knowledge and institutional support necessary to build and sustain high-tech ventures. But why are they not as successful as Corporate Startup Entrepreneurs (CSEs)? Empirical evidence suggests that differences in motivations, culture, knowledge, and identity could be the answer. USEs seek intellectual stimulation over financial success, struggle with accepting their entrepreneurial identity, and lack knowledge of the market and customers, putting them at a disadvantage compared to CSEs.

Tropospheric ozone (O3)  is a concerning pollutant, responsible for reduction in yields of major staple crops like rice, wheat, and maze. In this Journal of Environmental Sciences study, researchers from China and the United States of America found that rising O3 pollution led to national-level wheat, rice, and maize yield losses in China between 2005–2019. This trend was largely mitigated during COVID-19 lockdowns in 2020, indicating the need for an effective emission control policy.

Nanyang Technological University, Singapore (NTU Singapore) scientists have built the world’s first automated cyborg insect “factory line”. Supported by the Japan Science and Technology Agency (JST), this new prototype robotic system automates the attachment of miniature electronic backpacks on the back of Madagascar hissing cockroaches, turning them into insect-hybrid robots. This new assembly method significantly reduces preparation time and human error, marking a big step towards large-scale deployment of insect-hybrid robots in complex environments for search and rescue efforts in disaster zones. Led by Professor Hirotaka Sato from the School of Mechanical and Aerospace Engineering at NTU Singapore, the automated system can attach the electronic “backpacks” to Madagascar hissing cockroaches in just 1 minute and 8 seconds per insect. This is about 60 times faster than the traditional manual process dependent on trained operators, which often takes more than an hour. When processing four insects, the system completed all assemblies in under 8 minutes, about 30 times quicker than manual methods.

A research team led by Prof. CHENG Tianhai from the Aerospace Information Research Institute of the Chinese Academy of Sciences has made a breakthrough by developing a high-resolution satellite remote sensing method to quantify global methane emissions from landfills.

Researchers have developed a powerful new method to detect harmful blue-green algae in freshwater lakes, according to a new paper published a journal of the American Chemical Society
