Gait Analysis of Pak Biawak: A Necrobot Lizard Built using the Skeleton of an Asian Water Monitor (Varanus Salvator)

Advanced Robotics Research, EarlyView.
Pak Biawak, a necrobot, embodies an unusual fusion of biology and robotics. Designed to repurpose natural structures after death, it challenges conventional boundaries between nature and engineering. Its movements are precise yet unsettling, raising questions about sustainability, ethics, and the untapped potential of biointegrated machines.

The Deposition and Accumulation of Microplastics in Marine Sediments and Bottom Water from the Irish Continental Shelf [PDF]

, 2017
Microplastics are widely dispersed throughout the marine environment. An understanding of the distribution and accumulation of this form of pollution is crucial for gauging environmental risk.

Polylactic Acid (PLA), Polycaprolactone (PCL), and Chitosan: the Biodegradable Transition in Medical Waste Management

Advanced Sustainable Systems, EarlyView.
The shift to biodegradable materials in healthcare promises reduced plastic pollution, but their production, adoption, and long‐term impacts remain complex. Integrating lifecycle insights with global policy coordination is essential for meaningful environmental gains. Abstract The COVID‐19 pandemic sharply increased medical waste, intensifying concerns

Microplastics effects in Scrobicularia plana [PDF]

, 2017
One of the most common plastics in the marine environment is polystyrene (PS) that can be broken down to micro sized particles. Marine organisms are vulnerable to the exposure to microplastics.

Microplastics in freshwater environments

, 2023
Plastic pollution in aquatic environments is a recognized environmental threat on a global scale and is fed by the linear economy model of "make-use-dispose," which underpins both the fossil fuel and plastic industries. This chapter examines the issue of microplastic pollution in different freshwater environments: (i) rivers and tributaries, (ii) lakes,

PVC Nanoplastics Exposure Exacerbates Asthma through R‐Loop Accumulation and Subsequent STING Activation in Macrophages

Advanced Science, EarlyView.
Polyvinyl chloride (PVC) nanoplastics (NPs) are shown to aggravate allergic airway inflammation in asthma by triggering R‐loop accumulation and activating the cGAS‐STING pathway in macrophages. This study reveals a novel immunotoxic mechanism linking environmental plastic exposure to asthma pathogenesis and highlights potential molecular targets for ...

Adsorption of antibiotics on microplastics [PDF]

Environmental Pollution, 2018
Microplastics and antibiotics are two classes of emerging contaminants with proposed negative impacts to aqueous ecosystems. Adsorption of antibiotics on microplastics may result in their long-range transport and may cause compound combination effects. In this study, we investigated the adsorption of 5 antibiotics [sulfadiazine (SDZ), amoxicillin (AMX),
