Less than zero energy – quantum vacuum

by Vienna University of Technology Energy is a quantity that must always be positive—at least that’s what our intuition tells us. If every single particle is removed from a certain volume until there is nothing left that could possibly carry energy, then a limit has been reached. Or has it? Is it still possible to extract […]

A new way to corrosion-proof thin atomic sheets

Ultrathin coating could protect 2D materials from corrosion, enabling their use in optics and electronics. David L. Chandler | MIT News OfficeOctober 4, 2019 A variety of two-dimensional materials that have promising properties for optical, electronic, or optoelectronic applications have been held back by the fact that they quickly degrade when exposed to oxygen and […]

Artificial gut aims to expose the elusive microbiome

Testing platform will allow the research community to explore the human microbiome in new ways. Anne McGovern | Lincoln LaboratoryOctober 3, 2019 The microbiome is a collection of trillions of bacteria that reside in and on our bodies. Each person’s microbiome is unique — just like a fingerprint — and researchers are finding more and […]

Engineered viruses could fight drug resistance

By tweaking bacteriophage genomes, MIT team creates a new weapon to combat infection. Anne Trafton | MIT News OfficeOctober 3, 2019 In the battle against antibiotic resistance, many scientists have been trying to deploy naturally occurring viruses called bacteriophages that can infect and kill bacteria. Bacteriophages kill bacteria through different mechanisms than antibiotics, and they […]

This is how a “fuzzy” universe may have looked

Scientists simulate early galaxy formation in a universe of dark matter that is ultralight, or “fuzzy,” rather than cold or warm. Jennifer Chu | MIT News OfficeOctober 3, 2019 Dark matter was likely the starting ingredient for brewing up the very first galaxies in the universe. Shortly after the Big Bang, particles of dark matter […]

Controlling 2-D magnetism with stacking order

MIT researchers discover why magnetism in certain materials is different in atomically thin layers and their bulk forms. Denis Paiste | Materials Research LaboratorySeptember 30, 2019 Researchers led by MIT Department of Physics Professor Pablo Jarillo-Herrero last year showed that rotating layers of hexagonally structured graphene at a particular “magic angle” could change the material’s electronic properties […]

3Q: Scientists shave estimate of neutrino’s mass in half

Joseph Formaggio explains the discovery that the ghostly particle must be no more than 1 electronvolt, half as massive as previously thought. Jennifer Chu | MIT News OfficeSeptember 16, 2019 An international team of scientists, including researchers at MIT, has come closer to pinning down the mass of the elusive neutrino. These ghost-like particles permeate […]

Columbia Scientists Demonstrate Power of High-Speed Microscope to Illuminate Biology at the Speed of Life

New SCAPE 2.0 system can serve as a critical tool to advance science and medicine September 27, 2019 New York | Columbia University News The Columbia team behind the revolutionary 3D SCAPE microscope announces today a new version of this high-speed imaging technology. In collaboration with scientists from around the world, they used SCAPE 2.0 […]

Technique can image individual proteins within synapses

Rapid imaging method could help reveal how conditions such as autism affect brain cells. Anne Trafton | MIT News OfficeSeptember 26, 2019 Our brains contain trillions of synapses — the connections that transmit messages from neuron to neuron. Within these synapses are hundreds of different proteins, and dysfunction of these proteins can lead to conditions […]

To divide or not to divide?

Whitehead Institute team reveals molecular program that controls cells’ capacity for division. Nicole Davis | Whitehead Institute  | MIT News Cells in the body proliferate at different rates. Some divide constantly and throughout life, like the ones that line the gut. Others divide only rarely, sometimes resting for several years in a non-dividing state. Now, […]
