Photovoltaic (PV) technologies, which convert light into electricity, are increasingly applied worldwide to generate renewable energy. Researchers have now developed a molecular treatment that significantly enhances the efficiency and durability of perovskite solar cells. Their breakthrough will potentially accelerate the large-scale production of this clean energy.

Scientists uncover a pivotal enzyme, XccOpgD, and its critical role in synthesizing C G16, a key compound used by Xanthomonas pathogens to enhance their virulence against plants. This breakthrough opens new avenues for developing targeted pesticides that combat plant diseases without harming beneficial organisms. Insights into XccOpgD's enzymatic mechanism and optimal conditions offer promising prospects for sustainable agriculture, bolstering crop resilience and global food security while minimizing environmental impact.

Current climate policies imply a high risk for tipping of critical Earth system elements, even if temperatures return to below 1.5 C of global warming after a period of overshoot. A new study indicates that this risk can be minimized if the warming is swiftly reversed. That is why reducing emissions in the current decade is crucial for the stability of the Earth systems functions, researchers write. They analyzed the tipping risks for four interconnected core climate tipping elements: the Greenland Ice Sheet, the West Antarctic Ice Sheet, the Atlantic Meridional Overturning Circulation (AMOC), and the Amazon Rainforest.

Study finds that the mass extinction caused by an asteroid about 66 million years ago led to critical changes in bird genomes that ultimately sparked the incredibly diversity living birds.

A recent U.S. Supreme Court decision to block a federal rule curbing interstate air pollution further complicates efforts to reduce emissions and adds to an already disproportionate burden on 'downwind' states, according to researchers.

Researchers have uncovered surprising insights into the Vancouver region's 'smellscape' using data from the Smell Vancouver app. Analyzing 549 reports from one year of app data, they discovered that 'rotten' and 'chemical' odours dominated, making up about 65 per cent of submissions. These unpleasant smells were linked to self-reported health issues like headaches and anxiety, leading some residents to change their behaviours, like closing windows even in stifling-hot weather.

New research led proposes a plan to safeguard Earth's imperiled biodiversity by cryogenically preserving biological material on the moon. The moon's permanently shadowed craters are cold enough for cryogenic preservation without the need for electricity or liquid nitrogen.

A study reveals that tropical cyclones in Southeast Asia are now forming closer to coastlines, intensifying more rapidly, and lingering longer over land.

A new study has revealed how even the deepest seafloors are affected by the daily back-and-forth of the tides, and the change of the seasons, and that currents at the bottom of the ocean are far more complicated than previously thought. These findings are helping us understand the deep-sea pathways of nutrients that support important deep-sea ecosystems, assess where microplastics and other pollutants accumulate in the ocean, and reconstruct past climate change.

Forecasting European winter weather patterns months in advance is made simpler during years of strong El Ni o or La Ni a events in the tropical Pacific Ocean, a new study has found.

Scientists have detected geochemical signatures of magma pooling and melting beneath the subsurface during the 'Fagradalsfjall Fires', that began on Iceland's Reykjanes peninsula in 2021. Samples show that the start of the eruption began with massive pooling of magma, contrasting initial hypothesis for magma ascent straight from the mantle.

Researchers have developed a model that more accurately predicts how genetics and air pollution levels causally influence disease development.

Nanozymes are tiny, engineered substances that mimic the catalytic properties of natural enzymes, and they serve a variety of purposes in biomedicine, chemical engineering, and environmental applications. They are typically made from inorganic materials, including metal-based elements, which makes them unsuitable for many purposes due to their toxicity and high production costs. Organic-based nanozymes partially overcome some of these problems and have the potential for a broader range of applications, including food and agriculture, but they are still in the early stages of development. A new paper provides an overview of the current state of organic nanozymes and their future potential.

July 22, 2024, was the hottest day on record, according to a NASA analysis of global daily temperature data. July 21 and 23 of this year also exceeded the previous daily record, set in July 2023. These record-breaking temperatures are part of a long-term warming trend driven by human activities, primarily the emission of greenhouse gases.

Sapphires are among the most precious gems, yet they consist solely of chemically 'contaminated' aluminum oxide, or corundum. It is widely assumed that these crystals with their characteristically blue color come from deep crustal rocks and accidentally ended up on the Earth's surface as magma ascended. Geoscientists have now been able to show that the sapphire grains found in the Eifel (Germany) formed in association with volcanism.

Climate-driven shifts in California's biodiversity call for innovation and continued environmental stewardfship, says a new study. California's 30x30 Initiative and efforts to harmonize biodiversity with renewable energy are promising steps, while wildfire strategies need to further adapt.

Emphasizing local food production over imported substitutes can lead to significant cost and carbon savings, according to data from the Inuvialuit Settlement Region in the Canadian Arctic. The research shows potential annual savings of more than 3.1 million Canadian dollars and roughly half the carbon emissions when locally harvested food is used instead of imported food. The study underscores the importance of climate change policies that take local food systems into account. Weakening of these local systems could lead to increased emissions and jeopardize the health and food security of remote communities.
