Microalgae such as the diatom Odontella aurita and the green alga Tetraselmis striata are especially suitable as 'biofactories' for the production of sustainable materials for 3D laser printing due to their high content in lipids and photoactive pigments. An international research team has succeeded for the first time in manufacturing inks for printing complex biocompatible 3D microstructures from the raw materials extracted from the microalgae.

The key finding was that temperature and genome size, not body size, had the greatest influence on the maximum population growth rate of the diatoms. Yet body size still mattered in colder latitudes, conserving Bermann's Rule.

Machine learning is a powerful tool in computational biology, enabling the analysis of a wide range of biomedical data such as genomic sequences and biological imaging. But when researchers use machine learning in computational biology, understanding model behavior remains crucial for uncovering the underlying biological mechanisms in health and disease. Researchers now propose guidelines that outline pitfalls and opportunities for using interpretable machine learning methods to tackle computational biology problems.

Scientists have recovered the first long section of rocks that originated in the Earth's mantle, the layer below the crust and the planet's largest component. The rocks will help unravel the mantle's role in the origins of life on Earth, the volcanic activity generated when it melts, and how it drives the global cycles of important elements such as carbon and hydrogen.

Semiconductor industry waste is typically seen as a costly disposal problem and an environmental hazard. But what if this waste could be transformed into a valuable resource? In an exciting development, researchers have unveiled an eco-friendly method to extract rare metals from semiconductor waste. This innovative approach not only recovers precious tungsten but also assesses its economic viability, offering a sustainable solution for waste management in the tech industry.

Researchers analyzed long-term aerosol satellite observation big data focusing on the Pacific Ocean downwind of China. Using a newly developed metric that considered aerosols as tracers, they detected altered atmospheric transport patterns associated with climate change. They observed that the distance of transboundary air pollution moving east from China had shortened. Thus, long-term satellite-based Earth observations are crucial for early climate change detection and accurate evaluation of this trend.

Nearly a quarter of children with recurrent wheezing have 'silent' lung infections that would be better treated with antiviral medications than commonly prescribed steroids that can carry lifelong side effects, new research reveals.

Researchers say they now know that offspring are inheriting dysfunction in their mitochondria as a result of their parents' substance abuse. This dysfunction causes these individuals to show early signs of age-related disease when they're still considered young, usually in their 40s.

There comes a point in the lives of young owl monkeys when they leave their parents and strike out on their own to find a mate. In a new study of a wild population of Azara's owl monkeys in northern Argentina, researchers reveal that a combination of social and ecological factors influences when these tree-dwelling monkeys peel away from their parents and siblings. According to their findings -- which were based on 25 years of genetic and demographic data for several generations of owl monkeys, covering more than 330 individuals -- none of the individuals, regardless of their sex, reproduced in the same group where they were born. In all cases, the researchers found, the animals either departed from their natal group or died before reproducing.

Researchers developed a way to fingerprint organofluorine compounds -- sometimes called 'forever chemicals' --which could help authorities trace them to their source when they end up in aquifers, waterways or soil.

In nematodes and humans, mitochondrial stress in the nervous system initiates a whole-body response that is most pronounced in the gut. A recent study showed that in nematodes, the odor of a pathogen triggers the nervous system to broadcast this response to the rest of the organism, prepping mitochondria in intestinal cells to fight a bacterial infection. Humans, too, may be able to sense pathogenic odors that prepare the gut for an infection.
