Technique identifies T cells primed for certain allergies or infections

Researchers develop a method to isolate and sequence the RNA of T cells that react to a specific target. Anne Trafton | MIT News OfficeNovember 19, 2019 When your immune system is exposed to a vaccine, an allergen, or an infectious microbe, subsets of T cells that can recognize a foreign intruder leap into action. […]

Protein imaging at the speed of life

With this capability, scientists can watch how proteins do their jobs properly—or how their shape-changing goes awry, causing disease. NOVEMBER 18, 2019 by University of Wisconsin – Milwaukee To study the swiftness of biology—the protein chemistry behind every life function—scientists need to see molecules changing and interacting in unimaginably rapid time increments—trillionths of a second or […]

A marvelous molecular machine

NOVEMBER 15, 2019 by Harrison Tasoff and Sonia Fernandez, University of California – Santa Barbara Squids, octopuses and cuttlefish are undisputed masters of deception and camouflage. Their extraordinary ability to change color, texture and shape is unrivaled, even by modern technology. Researchers in the lab of UC Santa Barbara professor Daniel Morse have long been interested […]

What survives, thrives and dominates over a thousand generations? The answer might be even more complex than thought

NOVEMBER 13, 2019 by Harvard University Aa team of scientists, led by Harvard researchers, has used a new method of DNA “re-barcoding” to track rapid evolution in yeast. The new approach, published in Nature, advances the field of organismic and evolutionary biology and holds promise for real-world results. The potential impact of the work can be illustrated […]

How the brain regulates variability in motor functions

“We have shown that the brain uses a sophisticated algorithm to regulate motor variability in a way that improves task performance.” NOVEMBER 8, 2019 by Leah Burrows, Harvard University Anyone who has ever tried to serve a tennis ball or flip a pancake or even play a video game knows, it is hard to perform the […]

Researchers discover how cells know their future and forget their past

NOVEMBER 7, 2019 by University of Copenhagen Stem cells all share the potential of developing into any specific cell in the body. Many researchers are therefore trying to answer the fundamental questions of what determines the cells’ developmental fate as well as when and why the cells lose the potential of developing into any cell. Now, […]

World-leading microscopes take candid snapshots of atoms in their ‘neighborhoods’

NOVEMBER 6, 2019 by Lawrence Berkeley National Laboratory Researchers from MIT will be collaborating with colleagues at the University of Colorado at Boulder on an experiment scheduled to be sent to the International Space Station (ISS) on Nov. 2. The experiment is looking for ways to address the formation of biofilms on surfaces within the space station. These […]

New process could make hydrogen peroxide available in remote places

MIT-developed method may lead to portable devices for making the disinfectant on-site where it’s needed. David L. Chandler | MIT News Office October 23, 2019 Hydrogen peroxide, a useful all-purpose disinfectant, is found in most medicine cabinets in the developed world. But in remote villages in developing countries, where it could play an important role […]

Biologists build proteins that avoid crosstalk with existing molecules

Engineered signaling pathways could offer a new way to build synthetic biology circuits. Anne Trafton | MIT News OfficeOctober 23, 2019 Inside a living cell, many important messages are communicated via interactions between proteins. For these signals to be accurately relayed, each protein must interact only with its specific partner, avoiding unwanted crosstalk with any […]

Whitehead Institute team resolves structure of master growth regulator

New research reveals how mTORC1 docks at lysosomal surface. Nicole Davis | Whitehead InstituteOctober 18, 2019 A team of Whitehead Institute scientists has for the first time revealed the molecular structure of a critical growth regulator bound to its partner proteins, creating a fine-grained view of how they interact to sense nutrient levels and control […]
