Published Are conferences worth the time and money?
(via sciencedaily.com) Original source Scientists who interact with others during assigned sessions at conferences are more likely to form productive collaborations than scientists who do not, researchers found. And the kicker? It doesn't matter whether the conference is in person or virtual.
Published How to clean solar panels without water
(via sciencedaily.com) Dust that accumulates on solar panels is a major problem, but washing the panels uses huge amounts of water. Engineers have now developed a waterless cleaning method to remove dust on solar installations in water-limited regions, improving overall efficiency.
Published Brain-based computing chips not just for AI anymore
(via sciencedaily.com) With the insertion of a little math, researchers have shown that neuromorphic computers, which synthetically replicate the brain's logic, can solve more complex problems than those posed by artificial intelligence and may even earn a place in high-performance computing. Neuromorphic simulations employing random walks can track X-rays passing through bone and soft tissue, disease passing through a population, information flowing through social networks and the movements of financial markets.
Published A cautionary tale of machine learning uncertainty
(via sciencedaily.com) A new analysis shows that researchers using machine learning methods could risk underestimating uncertainties in their final results.
Published Stalagmites trace climate history and impact from volcanic eruptions
(via sciencedaily.com) The soils and vegetation of Patagonia's fjord regions form a unique and highly sensitive ecosystem that is closely linked to marine ecosystems, sediment deposition and carbon storage in the ocean. A research team has been working on reconstructing the climate history of this region in this extremely wet, rainy and inaccessible fjord and island zone of the Patagonian Andes in southern Chile. Due to its location, the area is a key region for understanding the history of the southern westerly wind belt within the global climate system.
Published Large mammals can help climate change mitigation and adaptation
(via sciencedaily.com) A new study investigates whether protecting and restoring large animal wildlife can help to support climate change goals.
Published Following rain, desert microbes exhale potent greenhouse gas
(via sciencedaily.com) New research shows how, after it rains, microbes in desert soil convert one form of pollution into another -- laughing gas.
Published Mathematical discovery could shed light on secrets of the Universe
(via sciencedaily.com) How can Einstein's theory of gravity be unified with quantum mechanics? It is a challenge that could give us deep insights into phenomena such as black holes and the birth of the universe. Now, a new article presents results that cast new light on important challenges in understanding quantum gravity.
Published Dark energy: Neutron stars will tell us if it's only an illusion
(via sciencedaily.com) Scientists provide the first simulation of neutron star collisions in extensions of general relativity relevant for cosmology, offering a new approach to test gravity.
Published For new insights into aerodynamics, scientists turn to paper airplanes
(via sciencedaily.com) Original source A series of experiments using paper airplanes reveals new aerodynamic effects, a team of scientists has discovered. Its findings enhance our understanding of flight stability and could inspire new types of flying robots and small drones.
Published These solar panels pull in water vapor to grow crops in the desert
(via sciencedaily.com) Using a unique hydrogel, scientists have created a solar-driven system that successfully grows spinach by using water drawn from the air while producing electricity. The proof-of-concept design offers a sustainable, low-cost strategy to improve food and water security for people living in dry-climate regions.
Published Being near pollinator habitat linked to larger soybean size
(via sciencedaily.com) Researchers have found that soybean crops planted near pollinator habitat produce larger soybeans than soybean crops that are not planted near pollinator habitat.
Published Risk of soil degradation and desertification in Europe’s Mediterranean may be more serious than realized
(via sciencedaily.com) Due to human-caused pressures and global warming, some soils in Europe's Mediterranean region are reaching what the researchers refer to as 'critical limits for their ability to provide ecosystem services,' which include farming and absorbing carbon, among others. Perhaps even more troubling, the problem could be even more extensive than we realize, says an author of a new study.
Published What lies beneath: Roots as drivers of South African landscape pattern
(via sciencedaily.com) Research findings suggest that alternative stable states can be maintained through biotic mechanisms, such as root traits, in addition to the commonly understood abiotic factors like climate. This insight is critical to conserving threatened ecosystems around the world.
Published Ancient Mesopotamian discovery transforms knowledge of early farming
(via sciencedaily.com) Researchers have unearthed the earliest definitive evidence of broomcorn millet (Panicum miliaceum) in ancient Iraq, challenging our understanding of humanity's earliest agricultural practices.
Published Watering holes bring together wildlife, and their parasites
(via sciencedaily.com) The sun rises on the savannas of central Kenya. Grasses sway in the wind as hoof-steps fall on the dusty ground. A menagerie of Africa's iconic wildlife congregates around a watering hole to quench their thirst during the region's dry season.
Published Hidden order in windswept sand
(via sciencedaily.com) Researchers have analyzed an extensive collection of sand samples from so-called megaripple fields around the world and gained new insights into the composition of these sand waves. These could help settle debates about the mechanistic origin of some recently discovered enigmatic extraterrestrial sand structures and improve our ability to infer information about past weather and climate events from sediment records.
Published Iodine in desert dust destroys ozone
(via sciencedaily.com) When winds loft fine desert dust high into the atmosphere, iodine in that dust can trigger chemical reactions that destroy some air pollution, but also let greenhouse gases stick around longer. The finding may force researchers to re-evaluate how particles from land can impact the chemistry of the atmosphere.
Published Desert shrubs cranked up water use efficiency to survive a megadrought
(via sciencedaily.com) Shrubs in the desert Southwest have increased their water use efficiency at some of the highest rates ever observed to cope with a decades-long megadrought. Researchers found that although the shrubs' efficiency increases are unprecedented and heroic, they may not be enough to adapt to the long-term drying trend in the West.
Published Collapse of ancient Liangzhu culture caused by climate change
(via sciencedaily.com) Referred to as 'China's Venice of the Stone Age', the Liangzhu excavation site in eastern China is considered one of the most significant testimonies of early Chinese advanced civilization. More than 5000 years ago, the city already had an elaborate water management system. Until now, it has been controversial what led to the sudden collapse. Massive flooding triggered by anomalously intense monsoon rains caused the collapse, as geologists and climate researchers have now shown.
