AI advancements make the leap into 3D pathology possible      (via sciencedaily.com)     Original source 

Researchers present Tripath: new, deep learning models that can use 3D pathology datasets to make clinical outcome predictions. The research team imaged curated prostate cancer specimens, using two 3D high-resolution imaging techniques. The models were then trained to predict prostate cancer recurrence risk on volumetric human tissue biopsies. By comprehensively capturing 3D morphologies from the entire tissue volume, Tripath performed better than pathologists and outperformed deep learning models that rely on 2D morphology and thin tissue slices.

An adjuvant made in yeast could lower vaccine cost and boost availability      (via sciencedaily.com)     Original source 

Adjuvants make vaccines more effective, though one of the best is an expensive extract from the soap bark tree. To lower the cost and avoid the laborious extraction process from bark, synthetic biologists introduced 38 separate genes into yeast to recreate the synthesis of the active molecule, a complex chemical, QS-21, that has a terpene core and numerous sugars. This may be the longest biosynthetic pathway ever inserted into yeast.

Genomes of 'star algae' shed light on origin of plants      (via sciencedaily.com)     Original source 

Land plants cover the surface of our planet and often tower over us. They form complex bodies with multiple organs that consist of a broad range of cell types. Developing this morphological complexity is underpinned by intricate networks of genes, whose coordinated action shapes plant bodies through various molecular mechanisms. All of these magnificent forms burst forth from a one-off evolutionary event: when plants conquered Earth's surface, known as plant terrestrialization.
