UC Berkeley physicists used partially entangled atoms identical to the qubits in a quantum computer to demonstrate more precisely than ever before – to one part in a billion billion – that space is uniform in all directions and not squeezed.

The former city and now archaeological site called Cantona in the highlands east of Mexico City appears to have been abandoned nearly 1,000 years ago as a result of a prolonged dry spell that lasted about 650 years, according to a new study.

New research moves the wonder material graphene a major step closer to knocking silicon off as the dominant workhorse of the electronics industry. 

The flip side of Heisenberg’s uncertainty principle, the energy time uncertainty principle, establishes a speed limit for transitions between two states. UC Berkeley physical chemists have now proved this principle for transitions between states that are not entirely distinct, allowing the calculation of speed limits for processes such as quantum computing and tunneling.

Costs of early-childhood services may have climbed nearly twofold for parents over the last 17 years, but most of these workers have overall seen no change in real earnings in the same period, according to research led by UC Berkeley’s Center for the Study of Child Care Employment.

Thibault Duchemin grew up as the only hearing person in a family of four.   He has always understood the communication challenges that were a daily part of their lives. Now, he’s developed Transcense – a mobile app that aims to end some of the professional and social isolation caused by hearing loss. 

Historical California vegetation data that more than once dodged the dumpster have now proved their true value, documenting that a changing forest structure seen in the Sierra Nevada has actually happened statewide over the past 90 years.

An international group of scientists has recommended that the fateful Trinity nuclear test on July 16, 1945, be considered the dawn of a new geological age dubbed the Anthropocene – an era in which humans increasingly shape the planet.

Organic semiconductors are prized for light emitting diodes (LEDs), field effect transistors (FETs) and photovoltaic cells. As they can be printed from solution, they provide a highly scalable, cost-effective alternative to silicon-based devices. Uneven performances, however, have been a persistent problem. That’s now changed.

NASA’s Kepler Space Telescope has discovered a star with three planets only slightly larger than Earth.
