California could triple the population of endangered southern sea otters by repopulating San Francisco Bay.

Researchers at Imperial have shown how the chaotic electrical signals underlying irregular heart rhythms lead to the failure of standard treatments.

The researchers from Peter the Great St.Petersburg Polytechnic University and Institute of Problems of Mechanical Engineering of the Russian Academy of Sciences studied the distribution of hydrogen in metals in the process of standard testing for hydrogen cracking. They found that there is a surface effect that does not let hydrogen enter the metal. This can result in errors in industrial quality control of material, and to fundamental errors in terms of scientific research of hydrogen embrittlement.

In the not too distant future, we can expect to see our skies filled with unmanned aerial vehicles delivering packages, maybe even people, from location to location. Researchers from The University of Texas and MIT, in collaboration with Akselos, and Aurora Flight Sciences, are developing 'digital twins' that combine computational models and machine learning to predict vehicle health and enable autonomous decision-making at the edge.

Medical practitioners routinely outfit patients with devices ranging from cardiovascular stents, pacemakers, catheters, and therapeutic lenses to orthopedic, breast, dental, and cochlear implants and prostheses. In an article publishing in the SIAM Journal on Applied Mathematics, Raquel Bernardes, José Ferreira, Paula de Oliveira, Mario Grassi, and Manuel Nhangumbe present a mathematical model that explores the interactions between bacterial populations, the materials they colonize, and drugs delivered from the medical devices to which they adhere.
