Published Dampening the 'seeds' of hurricanes
(via sciencedaily.com) Original source Increased atmospheric moisture may alter critical weather patterns over Africa, making it more difficult for the predecessors of many Atlantic hurricanes to form, according to a new study.
Published Visual explanations of machine learning models to estimate charge states in quantum dots
(via sciencedaily.com) Original source To form qubit states in semiconductor materials, it requires tuning for numerous parameters. But as the number of qubits increases, the amount of parameters also increases, thereby complicating this process. Now, researchers have automated this process, overcoming a significant barrier to realizing quantum computers.
Published Antarctic ice shelves hold twice as much meltwater as previously thought
(via sciencedaily.com) Original source Slush -- water-soaked snow -- makes up more than half of all meltwater on the Antarctic ice shelves during the height of summer, yet is poorly accounted for in regional climate models. The findings could have profound implications for ice shelf stability and sea level rise.
Published Groundbreaking discovery: Zinc can make crop yields more climate-resilient
(via sciencedaily.com) Original source Climate change, drought, increased temperature and other stressors challenge agricultural sustainability. Researchers have now made an unexpected discovery: zinc plays a pivotal role in the plant response to abiotic stress. This groundbreaking discovery not only sheds light on the intricate mechanisms of plant growth but also holds promise for revolutionizing crop resilience, especially in legume-based agriculture.
Published Common plastics could passively cool and heat buildings with the seasons
(via sciencedaily.com) Original source By restricting radiant heat flows between buildings and their environment to specific wavelengths, coatings engineered from common materials can achieve energy savings and thermal comfort that goes beyond what traditional building envelopes can achieve.
Published New twists on tornadoes: Earth scientist studies why U.S. has so many tornadoes
(via sciencedaily.com) Original source Across the Midwest during the warmer months, studying the sky for signs of storms and tornadoes becomes one of the most popular pastimes. Working at the intersection of climate science and meteorology and using modeling, scientists are looking at the big picture of what causes severe storms and tornadoes -- and what dictates where they occur.
Published Climate change and sea level rise pose an acute challenge for cities with combined sewer systems
(via sciencedaily.com) Original source Older coastal cities, like Philadelphia, New York and Boston are at risk of being inundated by untreated sewage during floods. Due in part to the design of their combined sewer systems and in part due to sea level rise, these cities could be facing a growing public health crisis as climate change also drives more extreme precipitation. The group recently published research that modeled the potential extent of the problem in a section of the coastal city of Camden, New Jersey, and the effectiveness of one proposed intervention to help protect these communities.
Published Understanding quantum states: New research shows importance of precise topography in solid neon qubits
(via sciencedaily.com) Original source A new study shows new insight into the quantum state that describes the condition of electrons on an electron-on-solid-neon quantum bit, information that can help engineers build this innovative technology.
Published El Niño forecasts extended to 18 months with innovative physics-based model
(via sciencedaily.com) Original source As more attention is drawn to possible severe weather around the world scientists are looking to improve planning for possible droughts, floods and other scenarios. A team of researchers created a new tool that will allow forecasting of El Nino Southern Oscillation by up to 18 months.
Published For many urban residents, it's even hotter than their weather app says
(via sciencedaily.com) Original source There's a strong chance that last week's scorching temperatures were even hotter than reported for those living in underserved urban areas. New research from environmental engineers has shown that citizen science tools used to gauge heat in these urban areas likely understate the problem of heat islands due to a lack of weather stations. The researchers also suggest a statistical method to improve estimates of urban heat.
Published Researchers discover new flat electronic bands, paving way for advanced quantum materials
(via sciencedaily.com) Original source Scientists predict the existence of flat electronic bands at the Fermi level, a finding that could enable new forms of quantum computing and electronic devices.
Published Human activity: A double-edged sword in the face of drought
(via sciencedaily.com) Original source A professor analyzes the conflicting impacts of human activities on extreme spring droughts.
Published Restoring the Great Salt Lake would have environmental justice as well as ecological benefits
(via sciencedaily.com) Original source Inland seas around the world are drying up due to increasing human water use and accelerating climate change, and their desiccation is releasing harmful dust that pollutes the surrounding areas during acute dust storms. Using the Great Salt Lake in Utah as a case study, researchers show that dust exposure was highest among Pacific Islanders and Hispanic people and lower in white people compared to all other racial/ethnic groups, and higher for individuals without a high school diploma. Restoring the lake would benefit everyone in the vicinity by reducing dust exposure, and it would also decrease the disparities in exposure between different racial/ethnic and socioeconomic groups.
Published Scientists at uOttawa develop innovative method to validate quantum photonics circuits performance
(via sciencedaily.com) Original source A team of researchers has developed an innovative technique for evaluating the performance of quantum circuits. This significant advancement represents a substantial leap forward in the field of quantum computing.
Published Hurricane changed 'rules of the game' in monkey society
(via sciencedaily.com) Original source A devastating hurricane transformed a monkey society by changing the pros and cons of interacting with others, new research shows.
Published Large wildfires create weather that favors more fire
(via sciencedaily.com) Original source A new study shows soot from large wildfires in California traps sunlight, making days warmer and drier than they ought to be.
Published Breakthrough may clear major hurdle for quantum computers
(via sciencedaily.com) Original source The potential of quantum computers is currently thwarted by a trade-off problem. Quantum systems that can carry out complex operations are less tolerant to errors and noise, while systems that are more protected against noise are harder and slower to compute with. Now a research team has created a unique system that combats the dilemma, thus paving the way for longer computation time and more robust quantum computers.
Published Effective hurricane risk messaging
(via sciencedaily.com) Original source Forecasters can use images in social media to better communicate weather related hazards of hurricanes, according to a pair of new studies.
Published New material puts eco-friendly methanol conversion within reach
(via sciencedaily.com) Original source Researchers have developed innovative, eco-friendly quantum materials that can drive the transformation of methanol into ethylene glycol. This discovery opens up new possibilities for using eco-friendly materials in photocatalysis, paving the way for sustainable chemical production.
Published Understanding the Green Sahara's collapse
(via sciencedaily.com) Original source Abrupt shifts within complex systems such as the Earth's climate system are extremely hard to predict. Researchers have now succeeded in developing a new method to anticipate such tipping points in advance. They successfully tested the reliability of their method using one of the most severe abrupt climate changes of the past: the shift of the once-green Sahara into a desert.
