The strikingly orange yeast Rhodotorula toruloides is already known for its ability to produce valuable oils and pigments. Researchers from the Tallinn University of Techology uncovered a new talent for this yeast: manufacturing sugar-based polymers that could replace synthetic materials with more sustainable, bio-based alternatives.

For years, scientists have worked to uncover how the brain responds to mechanical forces and electromagnetic waves. Computer models offer useful simulations, but they don’t fully capture what goes on inside a living brain. Now, the team from Mizzou’s College of Engineering is working to close that gap by developing 3D-printed models of an artificial human brain.

As an emerging technology in the field of artificial intelligence (AI), graph neural networks (GNNs) are deep learning models designed to process graph-structured data. Currently, GNNs are effective at capturing relationships between nodes and edges in data, but often overlook higher-order, complex connections. To address this challenge, a research team at The Hong Kong Polytechnic University (PolyU) has developed a new heterogeneous graph attention network, revolutionising the modelling of complex relationships in graph-structured data. This innovation is poised to break through AI application limitations in fields such as neuroscience, logistics, computer vision and biology.

Whatever challenges life throws, mothers often know best as they guide offspring through the risky stages of early development.  

Cannabis is increasingly normalized, but biology remains unchanged.
A review of 64 studies by researchers from Wroclaw Medical University shows that THC interferes with the endocannabinoid system — a key regulator of fertility, pregnancy, and fetal development.

THC affects the brain’s hormonal control centers, reproductive organs, and the placenta. In men, it is linked to poorer sperm quality and epigenetic changes; in women, to disrupted ovulation and impaired embryo implantation. During pregnancy, THC crosses the placenta, increasing the risk of low birth weight, prematurity, and neonatal complications, and is also present in breast milk.

There is no proven safe dose or safe form of cannabis. As legalization advances, the authors stress the need for clear guidance: avoiding cannabis when planning pregnancy, during pregnancy, and while breastfeeding is the safest choice.

To increase the power generated by solid oxide fuel cells (SOFCs), multiple cells have to be connected into a stack. Nonuniformity of cell performance is a worldwide concern in the practical application of stack, which is known to be unavoidable and caused by manufacturing and operating conditions. However, the effect of such nonuniformity on SOFCs that are connected in parallel has not been discussed in detail so far. This paper provides detailed experimental data on the current distribution within a stack with nonuniform cells in parallel connection, based on the basics of electricity and electrochemistry. Particular phenomena found in such a parallel system are the “self-discharge effect” in standby mode and the “capacity-proportional-load sharing effect” under normal operating conditions. It is believed that the experimental method and results proposed in this paper can be applied to other types of fuel cell or even other energy systems.

Researchers have learned how stingrays adjust for negative lift near the seafloor - being sucked downwards - and the discovery could help build smarter underwater robots that avoid disastrous ground collisions.
