Microplastics Spiral the Globe in the Atmosphere Image Credit: Shutterstock.com / Pcess609 The problem of plastic pollution may have gone airborne carried by the wind resulting in the ‘plastification’ of our planet. Microplastics have become an increasing source of concern for researchers and environmentalists. Traces of these tiny plastics can be found in every corner of the globe, throughout the food chain, and in drinking water, primarily due to water contamination. Marine ecosystems may not be the only environment widely invaded by microplastics, unfortunately. New research from scie...

It's common knowledge that trees are vital to removing carbon dioxide from the atmosphere. Reducing carbon dioxide levels is key in greenhouse gas cutting measures that could mitigate climate change. What is much less well-known is that trees also emit methane  —  a greenhouse gas that on a one-to-one basis can make a greater contribution to climate change than carbon dioxide. However, a new paper published in the jour...

How 3D Printing can Revolutionize Aircraft Maintenance and Repair THE HSE 180•S 3D printing platform. Image Credit: Essentium A new approach to advanced additive manufacturing could deliver faster and more efficient maintenance, repair and overhaul services for aircraft.  The maintenance of aircraft is a significant challenge for aerospace operators. The need to quickly repair machines and get them flightworthy, while also keeping costs low, is a high-pressure business.  Replacement parts for aging aircraft can be difficult to source as manufacturers tend to be reluctant to produce parts ...

Bacteria created this way could help researchers in the vital task of tracking changes in pollution levels over wide geographical areas.  Yet, whilst genetically modified microorganisms (GMMs) are great ...

The Artificial Intelligence Tool that can Detect Melanoma Image Credit: MIT A newly developed system could use neural networks to spot 'ugly duckling' pre-cancerous lesions on a patient's skin, potentially detecting cancer more efficiently.  Melanoma is a type of malignant tumor that is responsible for 70% of all skin cancer deaths. Of the 96,480 people diagnosed with melanoma in the US during 2019, reports indicate that 7230 passed away, making it the deadliest form of skin cancer. The key to preventing melanoma-related deaths is early identification. If doctors can spot the early cancer ...
