Nylon, the durable and elastic material, is like other plastics made from chemicals found in fossil fuels. Biodegradable plastics based on biomass-derived compounds are attracting attention as an alternative to conventional plastics, and Osaka Metropolitan University scientists have now synthesized biodegradable nylon precursors.

Professor Yutaka Amao’s team at the Research Center for Artificial Photosynthesis previously reported on a method for producing raw materials for biodegradable plastics from biomass-derived compounds. A polyester-type biodegradable plastic could be formed by using L-lactic acid as the raw material for polylactic acid.

This time, by using L-alanine, an amino acid with a similar structure, the team created raw material for a nylon-type biodegradable plastic. Artificial photosynthesis technology was developed with the addition of the biocatalyst L-alanine dehydrogenase, which combines ammonia with pyruvate to produce L-alanine, to the photoredox system composed of a dye and a catalyst.

“We have also succeeded in synthesizing the precursor of biodegradable nylon poly-L-alanine using solar energy,” Professor Amao declared. “In the future, we hope to achieve the synthesis of nylon precursors that have a low impact on the environment, with the aim of producing L-alanine through artificial photosynthesis using ammonia derived from biomass compounds.”

The findings were published in Sustainable Energy & Fuels.

GenEditScan: novel k-mer analysis tool based on next-generation sequencing for foreign DNA detection in genome-edited products
2025-01-22
Genetic changes have the ability to alter crop characteristics, and some crop breeding techniques take advantage of this. Conventionally, genetic engineering has relied on natural or artificial mutations. In recent years, genome editing technology has been grabbing attention. Genome editing technology can target and cut specific DNA sequences, causing mutations in target genes. This makes it possible to develop new cultivars efficiently. A common method for creating genome-edited crops involves introducing foreign DNA temporarily that produces an enzyme to cut the target ...

Dolphins use a 'fat taste' system to get their mother’s milk

Dolphins use a fat taste system to get their mother’s milk
2025-01-22
Juvenile dolphins were found to have specialized receptors for fatty acids on their tongues, offering new insights into their growth and feeding habits. Scientists have discovered that juvenile bottlenose dolphins have specialized receptors for detecting the fatty acids in their mother’s milk. These findings, published in the journal Marine Mammal Science, offer important insights into how these marine mammals grow, feed, and communicate. The new findings challenge previous assumptions about cetacean sensory systems. Unlike land mammals, dolphins and other marine mammals have limited olfactory capabilities – their sense of smell is largely ...

Clarifying the mechanism of coupled plasma fluctuations using simulations

Clarifying the mechanism of coupled plasma fluctuations using simulations
2025-01-22
Background In nature, phenomena in which multiple fluctuations occur in a coupled manner are frequently observed. For example, in large earthquakes, cases of them occurring consecutively in adjacent regions have been reported. When multiple fluctuations occur in this coupled way, compared to a single fluctuation, the coupled ones release more energy, leading to larger-scale phenomena. In fusion plasmas, fluctuations caused by energetic particles exist and are known to degrade the confinement of energetic particles. ...

Here’s what’s causing the Great Salt Lake to shrink, according to PSU study

2025-01-22
The Great Salt Lake, the largest saltwater lake in the Western Hemisphere, reached historic low levels in 2022, raising economic, ecological and public health concerns for Utah. New research from Portland State is believed to be the first peer-reviewed study that quantifies the contributing factors to the record low water volume levels, which the researchers say is important for anticipating and managing future lake changes. “The lake has a lot of social and economic relevance for the region and Utah,” said Siiri Bigalke, the lead author and a Ph.D. candidate in PSU’s Earth, ...

Can DNA-nanoparticle motors get up to speed with motor proteins?

Can DNA-nanoparticle motors get up to speed with motor proteins?
2025-01-22
DNA-nanoparticle motors are exactly as they sound: tiny artificial motors that use the structures of DNA and RNA to propel motion by enzymatic RNA degradation. Essentially, chemical energy is converted into mechanical motion by biasing the Brownian motion. The DNA-nanoparticle motor uses the "burnt-bridge" Brownian ratchet mechanism. In this type of movement, the motor is being propelled by the degradation (or "burning") of the bonds (or "bridges") it crosses along the substrate, essentially biasing its motion forward. These nano-sized motors are highly programmable and can be ...

Childhood poverty and/or parental mental illness may double teens’ risk of violence and police contact

2025-01-22
Living with persistent poverty and/or parental mental illness throughout childhood may double the risk of carrying and/or using a weapon and getting on the wrong side of the law by the age of 17, suggests research published online in the Journal of Epidemiology & Community Health. These factors may account for nearly 1 in 3 cases of weapon use or carriage and more than a quarter of all police contact among 17 year olds, nationwide, estimate the researchers. Youth crime and violence are common around the world, they note. In England and Wales, for example, around 104,400 first-time offenders were ...

Fizzy water might aid weight loss by boosting glucose uptake and metabolism

2025-01-22
Fizzy water might aid weight loss by boosting blood glucose uptake and metabolism—the rate at which the body uses and converts energy—but the effects are so small, drinking it can’t be relied on alone to shed the pounds, concludes a brief analysis published in the open access journal BMJ Nutrition Prevention & Health. There are no quick fixes to slimming down and keeping off the weight, says the author: regular physical activity and a healthy balanced diet are still essential, added to which the long term effects of drinking large amounts of carbonated water aren’t known. Because ...

Muscular strength and good physical fitness linked to lower risk of death in people with cancer

2025-01-22
Muscular strength and good physical fitness are linked to a significantly lower risk of death from any cause in people with cancer, finds a pooled data analysis of the available evidence, published online in the British Journal of Sports Medicine.   Tailored exercise to boost muscle strength and cardiorespiratory fitness in patients with cancer may help boost their chances of survival, suggest the researchers. In 2022 alone, 20 million people were diagnosed with cancer worldwide, and nearly ...
