New test may predict COVID-19 immunity

Paper test measures the level of neutralizing antibodies in a blood sample and could help people decide what protections they should take against infection

12-Aug-2022

Most people in the United States have some degree of immune protection against Covid-19, either from vaccination, infection, or a combination of the two. But, just how much protection does any individual person have? MIT researchers have now developed an easy-to-use test that may be able to ...

Breakthrough in sizing nanoparticles using fluid-filled tubes

Simple mechanical tube key to measuring mass and size of nano-particles simultaneously

31-Aug-2021

The functionality of nanoparticles in a host of applications, including drug delivery and nano-optics, is often dictated by their mass and size. Measuring these properties simultaneously for the same nanoparticle has also been challenging. Now scientists from the University of Melbourne and ...

New face mask prototype can detect Covid-19 infection

The sensor technology could also be used to create clothing that detects a variety of pathogens and other threats

01-Jul-2021

Engineers at MIT and Harvard University have designed a novel face mask that can diagnose the wearer with Covid-19 within about 90 minutes. The masks are embedded with tiny, disposable sensors that can be fitted into other face masks and could also be adapted to detect other viruses. The sensors ...

Finding the source of chemical reactions

06-Feb-2020

Scientists are constantly searching for the source of things like the origin of the universe, matter or life. Scientists at the U.S. Department of Energy's (DOE) Argonne National Laboratory, in a collaboration with the Massachusetts Institute of Technology (MIT) and several other universities, ...

DNA study casts light on century-old mystery of how cells divide

22-Jan-2018

Scientists have solved a longstanding puzzle of how cells are able to tightly package DNA to enable healthy cell division. Their findings shed light on how single cells can compact DNA 10,000-fold to partition it between two identical cells - a process that is essential for growth, repair and ...

Mapping the effects of crystal defects

16-Mar-2017

New research offers insights into how crystal dislocations -- a common type of defect in materials -- can affect electrical and heat transport through crystals, at a microscopic, quantum mechanical level. Dislocations in crystals are places where the orderly three-dimensional structure of a ...

Precise technique tracks dopamine in the brain

07-Mar-2017

MIT researchers have devised a way to measure dopamine in the brain much more precisely than previously possible, which should allow scientists to gain insight into dopamine's roles in learning, memory, and emotion. Dopamine is one of the many neurotransmitters that neurons in the brain use to ...

Tiny fibers open new windows into the brain

Three-in-one design allows genetic, chemical, optical, and electrical inputs and outputs.

24-Feb-2017

For the first time ever, a single flexible fiber no bigger than a human hair has successfully delivered a combination of optical, electrical, and chemical signals back and forth into the brain, putting into practice an idea first proposed two years ago. With some tweaking to further improve its ...

New resource for optical chips

22-Feb-2017

The Semiconductor Industry Association has estimated that at current rates of increase, computers’ energy requirements will exceed the world’s total power output by 2040. Using light rather than electricity to move data would dramatically reduce computer chips’ energy consumption, and the past 20 ...

A new contrast agent for MRI

New iron oxide nanoparticles could help avoid a rare side effect caused by current contrast agents

15-Feb-2017

A new, specially coated iron oxide nanoparticle developed by a team at MIT and elsewhere could provide an alternative to conventional gadolinium-based contrast agents used for magnetic resonance imaging (MRI) procedures. In rare cases, the currently used gadolinium agents have been found to ...
