Layers of carbon atoms in a honeycomb array are a true supermaterial: their unusually high conductivity and favorable mechanical properties could further the development of bendable electronics, new batteries, and innovative composite materials for aeronautics and space flight. However, the development of elastic and tough films remains a challenge. A research team has now introduced a method to overcome this hurdle: they linked graphene nanolayers via 'extendable' bridging structures.

Video footage of Iceland's 2010 Eyjafjallaj kull eruption is providing researchers with rare, up-close observations of volcanic ash clouds -- information that could help better forecast how far explosive eruptions disperse their hazardous ash particles.

Researchers found that U.S. adults are fairly confident in linking wildfires and heat to climate change, but less confident when it comes to other extreme weather events like hurricanes, flooding or tornadoes.

Data assimilation is an important mathematical discipline in earth sciences, particularly in numerical weather prediction (NWP). However, conventional data assimilation methods require significant computational resources. To address this, researchers developed a novel method to solve data assimilation on quantum computers, significantly reducing the computation time. The findings of the study have the potential to advance NWP systems and will inspire practical applications of quantum computers for advancing data assimilation.

Nanoscale electron transfer (ET) in solids is fundamental to the development of multifunctional materials. However, ET in solids is not yet clearly understood. Now, researchers achieved a direct observation of solid-state ET through X-ray crystal analysis by fabricating a novel double-walled non-covalent crystalline nanotube, which can absorb electron donor molecules and maintain its crystalline structure during ET. This innovative approach can lead to the design of novel functional materials soon.

Research has led to a new tool for forecasting coral disease that could help conservationists step in at the right times with key interventions. Ecological forecasts are critical tools for conserving and managing marine ecosystems, but few forecasting systems can account for the wide range of ecological complexities in near-real-time.

Engineers establish the link between oxygen and graphene quality and present an oxygen-free chemical vapor deposition method (OF-CVD) that can reproducibly create high-quality samples for large-scale production. The graphene they synthesized with their new method proved nearly identical to exfoliated samples and was capable of producing the fractional quantum Hall effect.

Advances in electrochromic coatings may bring us closer to environmentally friendly ways to keep inside spaces cool. Like eyeglasses that darken to provide sun protection, the optical properties of these transparent films can be tuned with electricity to block out solar heat and light. Now, researchers report demonstrating a new electrochromic film design based on metal-organic frameworks (MOFs) that quickly and reliably switch from transparent to glare-diminishing green to thermal-insulating red.

The Colorado River makes life possible in many Western cities and supports agriculture that sustains people throughout the country. Most of the river's water begins as snowmelt from the mountainous watersheds of Colorado, Utah, and Wyoming, and a warming climate will drastically reduce these streamflows, new research finds.

Researchers show that nocturnal heat significantly increases the risk of stroke. The findings can contribute to the development of preventive measures: With them, the population can better protect themselves against the risks of climate change with increasingly frequent hot nights. In addition, knowledge of the consequences of hot nights can improve patient care.

Sudden, severe dry spells known as flash droughts are rising in intensity around the world, with a notable exception in mountainous Central Asia, where flash drought extent is shrinking, according to new research. Heat and changes to precipitation patterns caused by a warming climate are driving these trends, the study found.
