Early Prediction of Alzheimer’s Progression: Blood protein

Years before symptoms of Alzheimer’s disease manifest, the brain starts changing and neurons are slowly degraded. Scientists at the German Center for Neurodegenerative Diseases (DZNE), the Hertie Institute for Clinical Brain Research (HIH) and the University Hospital Tuebingen now show that a protein found in the blood can be used to precisely monitor disease progression long before first clinical signs appear. This blood marker offers new possibilities for testing therapies. The study was carried out in cooperation with an international research team and published in the journal Nature Medicine.

“The fact that there is still no effective treatment for Alzheimer’s is partly because current therapies start much too late,” say...

Cultivating 4D Tissues: The Self-curving Cornea

The cornea moulds itself into a bowl-like structure over the course of 5 days. A three component gel comprising collagen, corneal stromal cells and peptide amphiphiles (inner circle) is combined with a two component gel comprising collagen and corneal stromal cells (outer circle). When triggered with a serum containing growth factors the outer ring of cells contracts more than the inner ring resulting in the progressive curvature of the structure.

Scientists at Newcastle University have developed a biological system which lets cells form a desired shape by moulding their surrounding material – in the first instance creating a self-curving cornea...

Using Bacteria to create a Water Filter that Kills Bacteria

Abstract Image
Photothermally Active Reduced Graphene Oxide/Bacterial Nanocellulose Composites as Biofouling-Resistant Ultrafiltration Membranes

New technology can clean water twice as fast as commercially available ultrafiltration membranes. Engineers have created a bacteria-filtering membrane using graphene oxide and bacterial nanocellulose. It’s highly efficient, long-lasting and environmentally friendly – and could provide clean water for those in need.

More than 1 in 10 people in the world lack basic drinking water access, and by 2025, half of the world’s population will be living in water-stressed areas, which is why access to clean water is one of the National Academy of Engineering’s Grand Challenges. Engineers at Washington University in St...

Scientists create a Renewable Source of Cancer-fighting T cells

Organoid-Induced Differentiation of Conventional T Cells from Human Pluripotent Stem Cells

A study by UCLA researchers is the first to demonstrate a technique for coaxing pluripotent stem cells – which can give rise to every cell type in the body and which can be grown indefinitely in the lab – into becoming mature T cells capable of killing tumor cells.

The technique uses structures called artificial thymic organoids, which work by mimicking the environment of the thymus, the organ in which T cells develop from blood stem cells.

T cells are cells of the immune system that fight infections, but also have the potential to eliminate cancer cells...
