Quantum researchers from CSIRO, Australia’s national science agency, have demonstrated the potential for quantum computing to significantly improve how we solve complex problems involving large datasets, highlighting the potential of using quantum in areas such as real-time traffic management, agricultural monitoring, health care, and energy optimization.

By leveraging the unique properties of quantum computing, like superposition and entanglement, researchers compressed and analyzed a large dataset with speed, accuracy, and efficiency that traditional computers cannot match.

The work is published in the journal Advanced Science.

A study has introduced a novel bioprocess that transforms CO2 and electricity into single-cell protein (SCP), a sustainable food source rich in essential amino acids.

<div class=””> <div class=””><br />Amino acids are a set of organic compounds used to build proteins. There are about 500 naturally occurring known amino acids, though only 20 appear in the genetic code. Proteins consist of one or more chains of amino acids called polypeptides. The sequence of the amino acid chain causes the polypeptide to fold into a shape that is biologically active. The amino acid sequences of proteins are encoded in the genes. Nine proteinogenic amino acids are called “essential” for humans because they cannot be produced from other compounds by the human body and so must be taken in as food.<br /></div> </div>

In the quest to take the “forever” out of “forever chemicals,” bacteria might be our ally. Most remediation of per-and polyfluoroalkyl substances (PFAS) involves adsorbing and trapping them, but certain microbes can actually break apart the strong chemical bonds that allow these chemicals to persist for so long in the environment.

Now, a University at Buffalo-led team has identified a strain of bacteria that can break down and transform at least three types of PFAS, and perhaps even more crucially, some of the toxic byproducts of the bond-breaking process.

Published in this month’s issue of Science of the Total Environment, the team’s study found that Labrys portucalensis F11 (F11) metabolized over 90% of perfluorooctane (PFOS) following an exposure period of 100 days. PFOS is one of the most frequently detected and persistent types of PFAS and was designated hazardous by the U.S. Environmental Protection Agency last year.

A major measles alert has been issued for two Australian states.

An urgent measles warning has been issued for two states after a toddler arrived in Australia from Vietnam with the infectious and deadly disease.

The South Australian government issued a warning after being notified of a three-year-old infected with measles travelling from Vietnam on Singapore Airlines flight SQ279, landing in Adelaide about 8.45am on Tuesday January 14.

Over the week, the toddler visited a number of places, including Kmart and Coles supermarket in Ingle Farm Shopping Centre on Wednesday January 15 before attending the Women’s and Children’s Hospital on Friday January 17.

The ability to regulate one’s own food intake is essential to the survival of both humans and other animals. This innate ability ensures that the body receives the nutrients it needs to perform daily activities, without significantly exceeding calorie intake, which could lead to health problems and metabolic disorders.

Past neuroscience studies suggest that the regulation of food intake is supported by specific regions in the brain, including the hypothalamus and caudal nucleus of the solitary tract (cNTS), which is part of the brainstem. This key region in the brainstem is known to integrate originating from the gut and then transform them into adaptive feeding behaviors.

While previous research has highlighted the key role of the cNTS in food intake regulation, the unique contribution of the different neuron subtypes within this brainstem region and the mechanisms by which they regulate feeding remain poorly understood. Better understanding these neuron-specific mechanisms could help to devise more effective therapeutic interventions for obesity and eating disorders.

A team of chemists and agriculture specialists has developed a way to transform urea in wastewater, into percarbamide, which can be used as a fertilizer. In their paper published in the journal Nature Catalysis, the group describes their process and how well the resulting product worked in growing edible crops.

Urine is seen as a source of because it is high in nitrogen and other rich compounds that are good for . Many home gardeners know that urine can be used as a fertilizer both for flower and vegetable gardens—the key is to mix it with a lot of water to prevent burning the plants.

Prior efforts to use urine as a source of fertilizer on a larger scale, however, have proven to be unfeasible due to industrial inefficiencies; it is much easier to use standard methods that involve extracting nitrogen from the air. In this new effort, the researchers have developed a way to use human and animal as a fertilizer for growing edible crops.

The rising trend of early-onset cancers in adults under 50, particularly women, is alarming. Genetic, lifestyle, and environmental factors contribute to this increase. Maintaining a healthy weight, quitting tobacco, avoiding alcohol, consuming fiber-rich foods, using sunscreen, and regular physical activity are small lifestyle changes that can significantly reduce cancer risk.
