Using remote sensing, geophysicists have documented the massive Feb. 6 quake that killed more than 50,000 people in Eastern Turkey and toppled more than 100,000 buildings. Alarmingly, researchers found that a section of the fault remains unbroken and locked -- a sign that the plates there may, when friction intensifies, generate another magnitude 6.8 earthquake when it finally gives way.

Perovskite solar cells (PSCs) are considered a promising candidate for next-generation photovoltaic technology with high efficiency and low production cost, potentially revolutionizing the renewable energy industry. However, the existing layer-by-layer manufacturing process presents challenges that have hindered the commercialization of this technology. Recently, researchers have developed an innovative one-step solution-coating approach that simplifies the manufacturing process and lowers the commercialization barriers for PSCs.

Even though most of the economic losses are concentrated in California and along the West Coast due to that region's high seismic hazard levels, significant population, and building exposure, earthquake risk is spread throughout the country. For example, there is a combined $3.1 billion per year in projected losses across the central U.S., Rocky Mountain region, Alaska, Hawaii, Puerto Rico and the Virgin Islands.

Mechanically responsive molecular crystals are extremely useful in soft robotics, which requires a versatile actuation technology. Crystals driven by the photothermal effect are particularly promising for achieving high-speed actuation. However, the response (bending) observed in these crystals is usually small. Now, scientists address this issue by inducing large resonated natural vibrations in anisole crystals with UV light illumination at the natural vibration frequency of the crystal.

The new classification system demonstrates the effects wetlands have on water quality at a continental scale -- invaluable data that can be used to better define whether wetlands are federally regulated under the U.S. Clean Water Act.

A new study found that signs of common infections in a sample of middle-aged and older adults were associated with poorer performance on a test of global cognitive function.

Recently quantum computers started to work with more than just the zeros and ones we know from classical computers. Now a team demonstrates a way to efficiently create entanglement of such high-dimensional systems to enable more powerful calculations.

Drinking cranberry juice has long been a mythical prevention strategy for women who develop a urinary tract infection -- and new medical evidence shows consuming cranberry products is an effective way to prevent a UTI before it gets started. A global study looking at the benefits of cranberry products has determined cranberry juice, and its supplements, reduce the risk of repeat symptomatic UTIs in women by more than a quarter, in children by more than half, and in people susceptible to UTI following medical interventions by about 53%.

Imagine the view from the western coastline of southern Africa during the Last Glacial Maximum (LGM) over twenty thousand years ago: in the distance you would see at least fifteen large islands -- the largest 300 square kilometers in area -- swarming with hundreds of millions of marine birds and penguin colonies.

The seven worst years for polar ice sheets melting and losing ice have occurred during the past decade, according to new research, with 2019 being the worst year on record. The seven worst years for polar ice sheets melting and losing ice have occurred during the past decade, according to new research, with 2019 being the worst year on record. The melting ice sheets now account for a quarter of all sea level rise -- a fivefold increase since the 1990's -- according to researchers who have combined 50 satellite surveys of Antarctica and Greenland taken between 1992 and 2020, funded by NASA and the European Space Agency.

There are high expectations that quantum computers may deliver revolutionary new possibilities for simulating chemical processes. This could have a major impact on everything from the development of new pharmaceuticals to new materials. Researchers have now used a quantum computer to undertake calculations within a real-life case in chemistry.

In the future, communications networks and computers will use information stored in objects governed by the microscopic laws of quantum mechanics. This capability can potentially underpin communication with greatly enhanced security and computers with unprecedented power. A vital component of these technologies will be memory devices capable of storing quantum information to be retrieved at will.
