New test detects compounds for disease diagnostics, environmental monitoring
07-Nov-2022
Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a fast and cost-effective method to test liquids for a ubiquitous family of chemical compounds known as amphiphiles, which are used to detect diseases such as early-stage tuberculosis and ...
Combination of nucleic acid nanotechnology and cryo-EM gives unprecedented insights into the structures of large and small RNAs
04-May-2022
We live in a world made and run by RNA, the equally important sibling of the genetic molecule DNA. In fact, evolutionary biologists hypothesize that RNA existed and self-replicated even before the appearance of DNA and the proteins encoded by it. Fast forward to modern day humans: science has ...
The results open new possibilities in research
02-Dec-2020
Induced pluripotent stem cells (iPS) have the potential to convert into a wide variety of cell types and tissues. However, the "recipes" for this conversion are often complicated and difficult to implement. Researchers at the Center for Regenerative Therapies Dresden (CRTD) at TU Dresden, Harvard ...
Magneto-Archimedes levitation for identification of illicit drugs in powdered mixtures
11-Dec-2019
The composition of suspicious powders that may contain illicit drugs can be analyzed using a quick and simple method called magneto-Archimedes levitation (MagLev), according to a new study published in the journal Angewandte Chemie. A team of scientists at Harvard University, USA, has developed ...
New design doubles the efficiency of the metalens
23-Jan-2019
We live in a polarized world. No, we aren't talking about politics -- we're talking about light. Much of the light we see and use is partially polarized, meaning its electric field vibrates in specific directions. Lenses designed to work across a range of applications, from phone cameras to ...
Single-layer surface of nanostructures can be incorporated into commercial optical systems
23-Nov-2018
Today's optical systems -- from smartphone cameras to cutting-edge microscopes -- use technology that hasn't changed much since the mid-1700s. Compound lenses, invented around 1730, correct the chromatic aberrations that cause lenses to focus different wavelengths of light in different spots. ...
Evolving genetic barcodes show origin of cells in vivo
13-Aug-2018
All humans begin life as a single cell that divides repeatedly to form two, then four, then eight cells, all the way up to the ~26 billion cells that make up a newborn. Tracing how and when those 26 billion cells arise from one zygote is the grand challenge of developmental biology, a field that ...
3D printing technique enables faster, better, and cheaper models of patient-specific medical data
31-May-2018
What if you could hold a physical model of your own brain in your hands, accurate down to its every unique fold? That question moved Steven Keating, Ph.D., who had a baseball-sized tumor removed from his brain at age 26 while he was a graduate student at the MIT. By collecting his imaging data he ...

There's plenty that's striking about Phoroncidia rubroargentea, a species of spider native to Madagascar, starting with their size - at just three millimeters, they're barely larger than a few grains of salt. But the reason they caught Sarah Kariko's eye had more to do with their color. Unlike ...
10-Apr-2018
Researchers at Harvard Medical School, the University of California, San Francisco, and the University of Georgia have described how the protein that allows strep and staph bacteria to stick to human cells is prepared and packaged. The research could facilitate the development of new ...
