Published Improving perovskite solar cell resistance to degradation


Despite their huge potential, the way perovskite solar cells respond to external stimuli -- such as heat or moisture -- has a considerable impact on their stability. Researchers have identified the cause of degradation and developed a technique to improve stability, bringing us closer to widespread adoption of these cost-effective and efficient solar cells.
Published A new tool helps map out where to develop clean energy infrastructure


An update to the Energy Zones Mapping Tool, the Geospatial Energy Mapper is an online tool with an extensive catalog of mapping data for energy planning. It can help identify areas that are suitable for clean energy infrastructure projects.
Published Rodent extinctions in Hispaniola may have been caused by humans


Hispaniola once had among the highest diversity of rodents in the Caribbean. Today, only one rodent species remains, and its prospects for survival are uncertain. New carbon dates place the blame squarely on humans.
Published Solar-powered system converts plastic and greenhouse gases into sustainable fuels


Researchers have developed a system that can transform plastic waste and greenhouse gases into sustainable fuels and other valuable products -- using just the energy from the Sun.
Published New discovery of sunscreen-like chemicals in fossil plants reveals UV radiation played a part in mass extinction events


New research has uncovered that pollen preserved in 250 million year old rocks contain compounds that function like sunscreen, these are produced by plants to protect them from harmful ultraviolet (UV-B) radiation. The findings suggests that a pulse of UV-B played an important part in the end Permian mass extinction event.
Published More links aren't necessarily better for hybrid nanomaterials


Chemists have discovered more isn't always better when it comes to packing charge-acceptor molecules on the surface of semiconducting nanocrystals.
Published Cheap, sustainable hydrogen through solar power


A new kind of solar panel has achieved 9% efficiency in converting water into hydrogen and oxygen--mimicking a crucial step in natural photosynthesis. Outdoors, it represents a major leap in the technology, nearly 10 times more efficient than solar water-splitting experiments of its kind.
Published A step towards solar fuels out of thin air


Chemical engineers have invented a solar-powered artificial leaf, built on a novel electrode which is transparent and porous, capable of harvesting water from the air for conversion into hydrogen fuel. The semiconductor-based technology is scalable and easy to prepare.
Published Space solar power technology demo launched into orbit


The launch represents the first in-situ test of the technology to harvest solar energy in space and transmit it to Earth.
Published Improving the operational stability of perovskite solar cells


Scientists have found a way to improve the operational stability of perovskite solar cells, a crucial step towards their commercialization.
Published Bering Land Bridge formed surprisingly late during last ice age


A new study that reconstructs the history of sea level at the Bering Strait shows that the Bering Land Bridge connecting Asia to North America did not emerge until around 35,700 years ago, less than 10,000 years before the height of the last ice age (known as the Last Glacial Maximum). The findings indicate that the growth of the ice sheets -- and the resulting drop in sea level -- occurred surprisingly quickly and much later in the glacial cycle than previous studies had suggested.
Published The world's largest turbulence simulation unmasks the flow of energy in astrophysical plasmas


Researchers uncover the long-hidden process that helps explain why the Sun's corona can be vastly hotter than the solar surface that emits it.
Published Archaeologists uncover oldest known projectile points in the Americas


Archaeologists have uncovered projectile points in Idaho that are thousands of years older than any previously found in the Americas, helping to fill in the history of how early humans crafted and used stone weapons.
Published New study models the transmission of foreshock waves towards Earth


As the supersonic solar wind surges towards Earth, its interaction with our planet's magnetic field creates a shock to deflect its flow, and a foreshock filled with electromagnetic waves. How these waves can propagate to the other side of the shock has long remained a mystery.
Published The other paleo diet: Rare discovery of dinosaur remains preserved with its last meal


Microraptor was an opportunistic predator, feeding on fish, birds, lizards -- and now small mammals. The discovery of a rare fossil reveals the creature was a generalist carnivore in the ancient ecosystem of dinosaurs.
Published Scientists discover a novel photophysical mechanism that has achieved record-breaking efficiency for organic photovoltaics


Organic photovoltaics (OPVs) are a promising, economical, next-generation solar cell technology for scalable clean energy and wearable electronics. But the energy conversion loss due to the recombination of photogenerated charge carriers in OPVs has hindered further enhancement of their power conversion efficiency (PCE). Recently, researchers from City University of Hong Kong (CityU) overcame this obstacle by inventing a novel device-engineering strategy to successfully suppress the energy conversion loss, resulting in record-breaking efficiency.
Published Ammonium is the secret ingredient in stable, efficient, scalable perovskite solar cells


A new pathway to creating durable, efficient perovskite photovoltaics at industrial scale has been demonstrated through the first effective use of lead acetate as a precursor in making formamidinium-caesium perovskite solar cells.
Published What the inner ear of Europasaurus reveals about its life


Europasaurus is a long-necked, herbivorous dinosaur that lived in the Late Jurassic, about 154 million years ago, on a small island in modern-day Germany. Recently, scientists examined fossil braincase material of Europasaurus with the aid of micro-computed tomography (micro-CT). The digital reconstruction of the inner ear of Europasaurus gave the researchers new insights not only into its hearing ability, but also into its reproductive and social behavior.
Published Early forests did not significantly change the atmospheric CO2



Scientists have discovered that the atmosphere contained far less CO2 than previously thought when forests emerged on our planet, the new study has important implications for understanding how land plants affect the climate.
Published Tandem solar cell achieves 32.5 percent efficiency


Researchers report a new world record for tandem solar cells consisting of a silicon bottom cell and a perovskite top cell. The new tandem solar cell converts 32.5 percent of the incident solar radiation into electrical energy.
