Published Scientist helps link climate change to Madagascar's megadrought



A team reveals a clear link between human-driven climate change and the years-long drought currently gripping southern Madagascar.
Published Research examines tweets during Hurricane MarĂa to analyze social media use during disasters



Understanding how social media is used during a disaster can help with disaster preparedness and recovery for future events.
Published How climate change will impact food production and financial institutions



Researchers have developed a new method to predict the financial impacts climate change will have on agriculture, which can help support food security and financial stability for countries increasingly prone to climate catastrophes.
Published Novel robust-optimal controllers based on fuzzy descriptor system



The Takagi--Sugeno (T--S) fuzzy descriptor system offers a promising avenue for controlling non-linear systems but lacks optimal control strategies. Moreover, while robust control methods have been developed, they add additional complexity. To address these limitations, a team of researchers has developed novel optimal and robust-optimal controllers based on the T--S fuzzy descriptor model, holding great potential for enhanced autonomous systems.
Published Can language models read the genome? This one decoded mRNA to make better vaccines



Researchers developed a foundational language model to decode mRNA sequences and optimize those sequences for vaccine development. The tool shows broader promise as a means for studying molecular biology.
Published eDNA methods give a real-time look at coral reef health



The study underscores the crucial role of microbes in maintaining coral reef health, akin to the human gut microbiome. Hurricanes and disease outbreaks affect coral reef water microbial communities, leading to changes that may support further reef decline. Microbial analysis enables prompt assessment of disturbances' impacts on coral reefs, facilitating timely interventions to support reef ecosystems. Environmental DNA (eDNA) analysis offers a noninvasive approach to study coral microbial communities and diagnose reef health.
Published Tracing the largest solar storm in modern times from tree rings in Lapland



A research group was able to measure a spike in radiocarbon concentration of trees in Lapland that occurred after the Carrington flare. This discovery helps to prepare for dangerous solar storms.
Published Fans are not a magic bullet for beating the heat!



A new study throws cold water on the idea that fans can effectively cool you down during extremely hot weather events.
Published Experiencing extreme weather predicts support for policies to mitigate effects of climate change



Most Americans report having personally experienced the effects of extreme weather, according to new survey data. An analysis finds that a reported exposure to extreme weather is associated with support for a half-dozen pro-environmental government policies that are intended to mitigate the effects of climate change and are contained in the Inflation Reduction Act of 2022.
Published Computer scientists show the way: AI models need not be SO power hungry



The development of AI models is an overlooked climate culprit. Computer scientists have created a recipe book for designing AI models that use much less energy without compromising performance. They argue that a model's energy consumption and carbon footprint should be a fixed criterion when designing and training AI models.
Published Australia on track for unprecedented, decades-long megadroughts



Australia could soon see megadroughts that last for more than 20 years, according to new modelling. The researchers' bleak findings are before factoring in human impact on the climate since the Industrial Revolution. According to the scientists, the findings paint a worrying picture of future droughts in Australia that are far worse than anything in recent experience.
Published The math problem that took nearly a century to solve: Secret to Ramsey numbers



Little progress had been made in solving Ramsey problems since the 1930s. Now, researchers have found the answer to r(4,t), a longstanding Ramsey problem that has perplexed the math world for decades.
Published Simple equations clarify cloud climate conundrum



New analysis based on simple equations has reduced uncertainty about how clouds will affect future climate change.
Published Physics-based predictive tool will speed up battery and superconductor research



Researchers have developed physics-based guidelines that will benefit host-guest intercalated materials research. By using only two guest properties and eight host-derived descriptors, they correctly predicted the intercalation energies and stabilities of many host-guest systems. This work is an important advance that will minimize the extensive trial-and-error laboratory work that otherwise slows down research and development in battery and superconductor technologies.
Published Artificial intelligence boosts super-resolution microscopy



Generative artificial intelligence (AI) might be best known from text or image-creating applications like ChatGPT or Stable Diffusion. But its usefulness beyond that is being shown in more and more different scientific fields.
Published How extratropical ocean-atmosphere interactions can contribute to the variability of jet streams in the Northern Hemisphere



Ocean-atmosphere coupling, the exchange in energy between the ocean and atmosphere, influences teleconnection patterns, the climate effects across vast geographical areas. However, its impact outside the tropics is unclear. A group of researchers examined the effect of ocean coupling on atmospheric circulation patterns in the Northern Hemisphere. They found that extratropical ocean-atmosphere coupling enhances teleconnection patterns and causes more meandering westerly jet streams, which are linked to extreme weather events.
Published Artificial reef designed by MIT engineers could protect marine life, reduce storm damage



Engineers designed an 'architected' reef that can mimic the wave-buffering effects of natural reefs while providing pockets for marine life. The sustainable and cost-saving structure could dissipate more than 95 percent of incoming wave energy using a small fraction of the material normally needed.
Published Severe hurricanes boost influx of juveniles and gene flow in a coral reef sponge



A study is the first to evaluate substrate recolonization by sponges in the U.S. Virgin Islands after two catastrophic storms using genetic analyses to understand how much clonality verses sexual recruitment occurs on coral reefs post-storms. Results show that populations of clonal marine species with low pelagic dispersion, such as A. cauliformis, may benefit from increased frequency and magnitude of hurricanes to maintain genetic diversity and combat inbreeding, enhancing the resilience of Caribbean sponge communities to extreme storm events.
Published Rectifying AI's usage in the quest for thermoelectric materials



AI is revolutionizing the way researchers seek to identify new materials, but it still has some shortcomings. Now, a team of researchers has navigated AI's pitfalls to identify a thermoelectric material that boasts remarkable properties.
Published Unintended consequences of fire suppression



A new study reveals how fire suppression ensures that wildfires will burn under extreme conditions at high severity, exacerbating the impacts of climate change and fuel accumulation.
