Researchers show that brain organoids -- clumps of lab-grown neurons -- can integrate with rat brains and respond to visual stimulation like flashing lights.

A new biomaterial that can be injected intravenously, reduces inflammation in tissue and promotes cell and tissue repair. The biomaterial was tested and proven effective in treating tissue damage caused by heart attacks in both rodent and large animal models. Researchers also provided proof of concept in a rodent model that the biomaterial could be beneficial to patients with traumatic brain injury and pulmonary arterial hypertension.

A new species of microalgae was found in water from a home aquarium. While analyzing DNA samples taken from the algae, researchers discovered Medakamo hakoo, whose DNA sequence didn't match any on record. This new species is the smallest known freshwater green algae, with inherent qualities which enable it to be cultured stably at high density, meaning it could be effectively used to produce useful products for food and industry.

Scientists have created an AI system capable of generating artificial enzymes from scratch. In laboratory tests, some of these enzymes worked as well as those found in nature, even when their artificially generated amino acid sequences diverged significantly from any known natural protein.

The red junglefowl -- the wild ancestor of the chicken -- is losing its genetic diversity by interbreeding with domesticated birds, according to a new study.

Old Yellow Enzymes (OYEs) were discovered in the 1930s and have been the subject of much research ever since. This is because these biocatalysts -- coloured yellow by an auxiliary molecule -- are capable of performing reactions that are very valuable for the chemical industry, such as producing drug precursors or fragrances. Even though OYEs are found in many organisms, their natural role for these organisms has hardly been understood so far -- possibly because the research focus has been on their biotechnological application. Researchers have now shown that an OYE of the unicellular green alga Chlamydomonas reinhardtii is vital for this plant microorganism to protect itself from photooxidative stress.

Heliozoan axopodia are important for their motility. However, the underlying mechanism of their axopodial contraction has remained ambiguous. Recently, researchers have reported that microtubules are simultaneously cleaved at multiple sites, allowing the radiating axopodia in a heliozoan, Raphidocystis contractilis, to disappear almost instantly. They have now identified the gene set and proteins involved in this microtubule disruption. This research can help develop a method to detect water pollution and evaluate the efficacy of new anticancer drugs.

Many genetic diseases are caused by diverse mutations spread across an entire gene, and designing genome editing approaches for each patient's mutation would be impractical and costly.

With only two levels of superposition, the qubits used in today's quantum communication technologies have limited storage space and low tolerance for interference. Engineering's hyperdimensional microlaser generates 'qudits,' photons with four simultaneous levels of information. The increase in dimension makes for robust quantum communication technology better suited for real-world applications.
