Using a virus-like delivery particle made from DNA, researchers from MIT and the Ragon Institute of MGH, MIT, and Harvard have created a vaccine that can induce a strong antibody response against SARS-CoV-2. The vaccine, which has been tested in mice, consists of a DNA scaffold that carries many copies of a viral antigen. This …

Nerve cells in the brain demand an enormous amount of energy to survive and maintain their connections for communicating with other nerve cells. In Alzheimer’s disease, the ability to make energy is compromised, and the connections between nerve cells (called synapses) eventually come apart and wither, causing new memories to fade and fail. A research …

Researchers have designed a self-powering, battery-free, energy-harvesting sensor. Using the framework they developed, they produced a temperature sensor that can harvest and store the energy from the magnetic field that exists in the open air around a wire. ​Researchers have designed a self-powering, battery-free, energy-harvesting sensor.
