A novel technique to observe colloidal particle degradation in real time

In the early 2000s, scientists from the UK made a worrisome discovery that the oceans are teeming with small particles of plastic (less than one millimeter in length) due to the continuous degradation of plastic waste. These microscopic particles of plastic have become a major environmental concern. Scientists classify these small particles as either microplastics or nanoplastics based on their size; the latter term is used exclusively for particles smaller than one micrometer. These particles easily get embedded into the bodies of marine and freshwater animals, ...

Improving word intelligibility of bone-conducted speech using bone-conduction headphones

Ishikawa, Japan -- Bone-conduction (BC) headphones enhance hearing capability by generating vibrations in bone or skin close to the ear, including the regio temporalis. They simultaneously leave the ear canal open to allow the surrounding air-conducted (AC) sounds for normal hearing. However, word intelligibility – recognition ability – is often poor during bone-conducted speech perceived using BC headphones due to the attenuation of its high-frequency components, especially under noisy conditions. While inserting ear plugs in the ear canal help improve ...

Alcohol harm reduction can also reduce other substance use

SEATTLE, Wash. – Quitting alcohol or drugs was not a top priority for people experiencing homelessness in a harm reduction treatment study, yet participants still reduced their use of both. A different approach than traditional abstinence-based programs, harm reduction treatment for alcohol use disorder, also called HaRT-A, has patients set their own goals. In a study of 308 people experiencing homelessness, the participants receiving harm reduction treatment set goals of meeting basic needs and improving quality of life well above quitting alcohol and other substances. Yet harm reduction treatment still led to more reduced use compared to a control group who received ...

New way of identifying proteins supports drug development

All living cells contains proteins with different functions, depending on the type of cell. Researchers at the University of Gothenburg have discovered a way to identify proteins even without looking at their structure. Their method is faster, easier and more reliable than previous methods. Currently, the general view is that each protein’s structure is what controls its function in cells. The atomic sequences, meaning how the atoms are arranged in the proteins, create the protein’s structure and shape. But there are many proteins that lack a well-defined structure.

Prediction of age of onset of SCA3 and DRPLA by survival analysis using machine learning

Niigata, Japan – Using machine learning, the Department of Neurology at Niigata University has developed a model to predict the asymptomatic probability at each age from the current age and number of CAG repeats in carriers of spinocerebellar degeneration. Polyglutamine diseases such as DRPLA and SCA3 are caused by an expansion of CAG repeats in the causative gene. In polyglutamine diseases, the number of CAG repeats is known to be inversely related to age of onset. Parametric survival analysis has traditionally been used to predict age of onset, but a more accurate prediction method has been desired. We ...
