New findings help explain the surprising discovery that exposure to flickering light reduces amyloid plaques in mice. Several years ago, MIT neuroscientists showed that they could dramatically reduce the amyloid plaques seen in mice with Alzheimer’s disease simply by exposing the animals to light flickering at a specific frequency. In a new study, the researchers...

Algorithm stitches multiple datasets into a single “panorama,” which could provide new insights for medical and biological studies. A new algorithm developed by MIT researchers takes cues from panoramic photography to merge massive, diverse cell datasets into a single source that can be used for medical and biological studies. Single-cell datasets profile the gene expressions...

Researchers develop nanosized antibodies that home in on the meshwork of proteins surrounding cancer cells. The spread of malignant cells from an original tumor to other parts of the body, known as metastasis, is the main cause of cancer deaths worldwide. Early detection of tumors and metastases could significantly improve cancer survival rates. However, predicting...

Data-sampling method makes “sketches” of unwieldy biological datasets while still capturing the full diversity of cell types. Artistic sketches can be used to capture details of a scene in a simpler image. MIT researchers are now bringing that concept to computational biology, with a novel method that extracts comprehensive samples — called “sketches” — of...

Analysis of genes altered by the disease could provide targets for new treatments. MIT researchers have performed the first comprehensive analysis of the genes that are expressed in individual brain cells of patients with Alzheimer’s disease. The results allowed the team to identify distinctive cellular pathways that are affected in neurons and other types of...

More effective surgery could boost survival rates for ovarian cancer. Ovarian cancer is usually diagnosed only after it has reached an advanced stage, with many tumors spread throughout the abdomen. Most patients undergo surgery to remove as many of these tumors as possible, but because some are so small and widespread, it is difficult to...

The substance that bathes tumors in the body is quite different from the medium used to grow cancer cells in the lab, biologists report. Before being tested in animals or humans, most cancer drugs are evaluated in tumor cells grown in a lab dish. However, in recent years, there has been a growing realization that...

Machine learning can reveal optimal growing conditions to maximize taste and other features. What goes into making plants taste good? For scientists in MIT’s Media Lab, it takes a combination of botany, machine-learning algorithms, and some good old-fashioned chemistry. Using all of the above, researchers in the Media Lab’s Open Agriculture Initiative report that they...
