UMD engineers demonstrate their approach by printing the smallest-known 3D microfluidic circuit element. Engineers at the University of Maryland (UMD) have created the first 3D-printed fluid circuit element so tiny that 10 could rest on the width of a human hair. The diode ensures fluids move in only a single direction – a critical feature for products like implantable devices that release therapies directly into the body.

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...

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...

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...
