Measurements of the speed at which the universe is expanding today, referred to as the Hubble constant, allow us to test the accuracy of contemporary cosmological models. Some recent measurements of the Hubble constant suggest a significant gap in the leading Lambda cold dark matter paradigm, coined the Hubble Tension...

The Nearby Supernova Factory (SNfactory; Aldering+02,04) at Berkeley Lab has developed a model for inferring the distances between Type Ia supernovae (SNe Ia) that is about twice as accurate as previous ones. The model uses the spectral differences between different SNe to constrain variations in their intrinsic luminosities. The...

There has recently been a proposal for detecting millicharged dark matter (B. Gao et al. (2026), https://journals.aps.org/prl/abstract/10.1103/r3rb-zhyl) using arrays of Josephson junction-based sensors. It is known that not all the dark matter can be comprised of fractionally charged particles, but such particles arise...

The cosmic microwave background (CMB) is a unique window to fundamental physics. It can be used to probe primordial gravitational waves, which are a distinct sign that the early universe has experienced an exponentially rapid expansion at its age of ~10^-32 seconds. The CMB photons also probe the properties...

The Cosmic Microwave Background (CMB) is the oldest light in the Universe, and carries invaluable information about the Universe’s history and evolution. The detection of primordial gravitational waves in the CMB polarisation, a smoking gun for cosmic inflation, is one of the biggest challenges in observational cosmology. To achieve the...

Neutrino is a sub-atomic particle that was thought to be massless. Recently, a new phenomenon called neutrino oscillation, a transformation of one type of neutrino to another kind, has been discovered in experiments. These important findings imply that neutrinos have mass and they can mix among themselves. Neutrino oscillations...

Developing a deep understanding of complex public policy issues often requires more time than most citizens can reasonably devote. Because of this, political polls tend to measure people’s first impressions rather than what their more informed opinions might be. Deliberative Polling is a process designed to address this limitation. Participants...

It has been thought that the accelerated expansion of our universe is caused by an unknown "dark energy" which has a constant energy density. However, there are currently hints that dark energy is actually evolving over time. If this were true, there would be profound implications on fundamental physics and...
