Sediments may control location, magnitude of megaquakes  PHYS.ORG · 3 days
The world's most powerful earthquakes strike at subduction zones, areas where enormous amounts of stress build up as one tectonic plate dives beneath another. When suddenly released, this stress can cause devastating "megaquakes" like... more
New mechanism of optical gain in two-dimensional material requires only extremely low input power  PHYS.ORG · 2 weeks
Optical gain is a prerequisite for signal amplification in an optical amplifier or laser. It typically requires high levels of... more
A landmark plan for realizing fusion energy and advancing plasma science  PHYS.ORG · 2 weeks

Even a limited India-Pakistan nuclear war would bring global famine, says study  PHYS.ORG · 3 weeks
The concept of nuclear winter—a years-long planetary freeze brought on by airborne soot generated by nuclear bombs—has been around for decades. But such speculations... more
Shifts in deep geologic structure may have magnified great 2011 Japan tsunami  PHYS.ORG · 3 weeks
On March 11, 2011, a magnitude 9 earthquake struck under the seabed off Japan—the most powerful quake to hit the country in modern times,... more
The electronic thickness of graphene  Science Magazine · 3 weeks
When two dimensional crystals are atomically close, their finite thickness becomes relevant. Using transport measurements, we investigate the electrostatics of two graphene layers, twisted by = 22° such that the layers are decoupled by the huge momentum mismatch... more
Discovery of zero-energy bound states at both ends of a one-dimensional atomic line defect  nanowerk · 3 weeks
Scientists discovered Majorana zero modes at both ends of 1D atomic line defects in two-dimensional iron-based high-temperature superconductors. more
Discovery of zero-energy bound states at both ends of a one-dimensional atomic line defect  PHYS.ORG · 3 weeks
In recent years, the development of quantum computers beyond the capability of classical computers has become a new frontier in... more
Structure of V-ATPase from the mammalian brain  Science Magazine · 3 weeks
In neurons, the loading of neurotransmitters into synaptic vesicles uses energy from proton-pumping vesicular- or vacuolar-type adenosine triphosphatases (V-ATPases). These membrane protein complexes possess numerous subunit isoforms, which complicates their analysis. We isolated homogeneous... more
Quantum-nondemolition state detection and spectroscopy of single trapped molecules  Science Magazine · 3 weeks
Trapped atoms and ions, which are among the best-controlled quantum systems, find widespread applications in quantum science. For molecules, a similar degree of control is currently lacking owing to their... more
Permanent magnets stronger than those on refrigerator could be a solution for delivering fusion energy  PHYS.ORG · 3 weeks
Permanent magnets akin to those used on refrigerators could speed the development of fusion energy—the same energy produced... more
Feeding fusion: hydrogen ice pellets prove effective for fueling fusion plasmas  PHYS.ORG · 3 weeks
Researchers have found that injecting pellets of hydrogen ice rather than puffing hydrogen gas improves fusion performance at the DIII-D National Fusion Facility, which General Atomics... more
Electrical power generation from moderate-temperature radiative thermal sources  PHYS.ORG · 3 weeks
Moderate-temperature thermal sources often radiate waste heat as a by-product of mechanical work, chemical or nuclear reactions, or information processing. In a new report in Science, Paul S. Davids and a research... more
'Strange' glimpse into neutron stars and symmetry violation  PHYS.ORG · 4 weeks
New results from precision particle detectors at the Relativistic Heavy Ion Collider (RHIC) offer a fresh glimpse of the particle interactions that take place in the cores of neutron stars and give... more
