New measurement of universe’s expansion rate is ‘stuck in the middle’
A team of collaborators from Carnegie and the University of Chicago used red giant stars that were observed by the Hubble Space Telescope to...
Quantum photonics by serendipity
A photonic chip with no less than 128 tunable components proves to be a true computing "Swiss army knife" with a variety of applications....
Two-qubit gate: the speediest quantum operation yet
A group of scientists led by 2018 Australian of the Year Professor Michelle Simmons have achieved the first two-qubit gate between atom qubits in...
Ultrasound-assisted optical imaging to replace endoscopy in breakthrough discovery
Carnegie Mellon University's Assistant Professor of Electrical and Computer Engineering (ECE) Maysam Chamanzar and ECE Ph.D. student Matteo Giuseppe Scopelliti today published research that...
First-ever visualizations of electrical gating effects on electronic structure
Scientists have visualised the electronic structure in a microelectronic device for the first time, opening up opportunities for finely-tuned high performance electronic devices.
Physicists from...
Highly anticipated nuclear experiment underway
Neutron stars were recently in the news because the gravitational wave observatory, LIGO, detected a neutron star merger. Neutron stars are very interesting objects....
A graphene superconductor that plays more than one tune
Researchers at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a graphene device that's thinner than a human hair...
Timing is everything for the mutualistic relationship between ants and acacias
In the 1960s, Penn biologist Dan Janzen, as part of earning his Ph.D., re-described what has become a classic example of biological mutualism: the...
Avian malaria behind drastic decline of London’s iconic sparrow?
London's house sparrows (Passer domesticus) have plummeted by 71% since 1995, with new research suggesting avian malaria could be to blame.
Once ubiquitous across the...
Forces behind growing political polarization in congress revealed in new model
For much of the 20th century, political polarization within the United States House of Representatives tended to decrease over the course of a two-year...
Limitation exposed in promising quantum computing material
Quantum computers promise to perform operations of great importance believed to be impossible for our technology today. Current computers process information via transistors carrying...
