New method for detecting nanoplastics in body fluids
2025-04-14
Microplastics and the much smaller nanoplastics enter the human body in various ways, for example through food or the air we breathe. A large proportion is excreted, but a certain amount remains in organs, blood and other body fluids. In the FFG bridge project Nano-VISION, which was launched two years ago together with the start-up BRAVE Analytics, a team led by Harald Fitzek from the Institute of Electron Microscopy and Nanoanalysis at Graz University of Technology (TU Graz) and an ophthalmologist from Graz addressed the question of whether nanoplastics also play a role in ophthalmology. The project partners have now been able to develop a method for detecting and quantifying nanoplastics ...
Do disasters delay early cancer diagnoses?
2025-04-14
Rates of colorectal cancer (CRC) diagnoses dropped during and shortly after Hurricanes Irma and Maria and the COVID-19 pandemic in Puerto Rico, according to a recent analysis. However, late-stage diagnoses eventually exceeded expectations, suggesting that limited access to cancer screening services due to these disasters likely hindered timely CRC diagnoses. The findings are published by Wiley online in CANCER, a peer-reviewed journal of the American Cancer Society.
During disasters, medical services may be delayed or inaccessible due to damaged infrastructure, overburdened health ...
Rise and shine: Natural light lessens morning fatigue
2025-04-14
Sleep is a necessary part of people’s daily routine, but modern lifestyles and technology have ushered in an era of decreased rest time and subsequent fatigue. Further, the bedroom environment, such as light, sound, and temperature, is important for a good night's sleep, though this is often neglected in residential architecture.
In search of a conclusive remedy, common sleep studies use artificial light that is easy to control. Osaka Metropolitan University researchers, however, believe natural light could be more effective for re-creating actual living environments.
To test this, Graduate School of Human Life and Ecology student Xiaorui Wang and Professor ...
Nature’s plan for delaying pest resistance deciphered
2025-04-14
Farmers in dozens of countries have embraced crops genetically engineered to produce proteins from Bacillus thuringiensis (Bt) bacteria that kill some key pests yet are safe for people and wildlife. Although this biotech approach reduces reliance on insecticide sprays thereby providing economic and environmental benefits, resistance to Bt crops has evolved in at least 11 species of pests. Thus, effective ways to combat such pest resistance are urgently needed.
A new study published in the Proceedings of the National Academy of Sciences identifies a natural strategy for thwarting pest resistance to Bt proteins. The researchers at the University of Arizona and ...
