Published History repeats as Coral Bay faces mass loss of coral and fish life
(via sciencedaily.com) Original source A perfect storm of environmental factors has seen a monumental loss of fish and coral life at a popular area of Ningaloo Reef in Western Australia's Gascoyne region -- however research into the event shows there is hope it will recover. In March 2022, during the annual coral spawning event, calm weather and limited tidal movement combined to trap the coral's eggs within Bills Bay, at the town of Coral Bay. This led to an excess of nutrients in the water which consumed more oxygen than usual -- causing massive numbers of fish and corals to die from asphyxiation.
Published Rice paddy snake diversification was driven by geological and environmental factors in Thailand, molecular data suggests
(via sciencedaily.com) Original source A new study of rice paddy snakes in Southeast Asia gives key details to their diversification and natural history, adding molecular evidence that the rise of the Khorat Plateau and subsequent environmental shifts in Thailand may have altered the course of the snakes' evolution some 2.5 million years ago.
Published Mars attracts: How Earth's interactions with the red planet drive deep-sea circulation
(via sciencedaily.com) Original source Scientists have used the geological record of the deep sea to discover a connection between the orbits of Earth and Mars, past global warming patterns and the speeding up of deep ocean circulation. The patterns they discover suggest that warming seas could produce deep whirpools in ocean currents.
Published Pronghorn population declining due to human development
(via sciencedaily.com) Original source A new article looked at 40 years of data collected on 40 pronghorn herds residing in the Wyoming Basin Shrub Steppe. Overall, 80% of the herds saw a decrease in productivity, and nearly 43% saw a significant decrease. After looking at a number of variables that could potentially contribute to the decline, the researchers identified the two most strongly associated: development of oil and gas resources and woody encroachment.
Published Cicadas' unique urination unlocks new understanding of fluid dynamics
(via sciencedaily.com) Original source While most small insects and mammals urinate in droplets, cicadas urinate in jets. Researchers say the finding could be used to create better robots and small nozzles.
Published Design rules and synthesis of quantum memory candidates
(via sciencedaily.com) Original source In the quest to develop quantum computers and networks, there are many components that are fundamentally different than those used today. Like a modern computer, each of these components has different constraints. However, it is currently unclear what materials can be used to construct those components for the transmission and storage of quantum information.
Published Study explores impacts of Arctic warming on daily weather patterns in the U.S.
(via sciencedaily.com) Original source Arctic sea ice is shrinking as the world continues to warm, and a new study may provide a better understanding of how the loss of this ice may impact daily weather in the middle latitudes, like the United States.
Published Combined microscopy technique catches light-driven polymers in the act
(via sciencedaily.com) Original source Researchers have used tip-scan high-speed atomic force microscopy combined with an optical microscope to observe light-induced deformation of azo-polymer films. The process could be followed in real time, and the film patterns were found to change with the polarization of the light source. The observations will contribute to the use of azo-polymers in applications such as optical data storage, and the approach is expected to be useful across materials science and physical chemistry.
Published How surface roughness influences the adhesion of soft materials
(via sciencedaily.com) Original source A research team discovers universal mechanism that leads to adhesion hysteresis in soft materials. Through a combination of experimental observations and simulations, the team demonstrated that roughness interferes with the separation process, causing the materials to detach in minute, abrupt movements, which release parts of the adhesive bond incrementally. The findings will make it possible to specifically control the adhesion properties of soft materials through surface roughness and will allow new and improved applications to be developed in soft robotics or production technology in the future.
Published Mapping the future's sweet spot for clean energy and biodiversity
(via sciencedaily.com) Original source A new study of Joshua trees, kit foxes and solar energy developments highlights the need to consider climate-induced range shifts for species as we expand clean energy.
Published Tiny wireless light bulbs for biomedical applications
(via sciencedaily.com) Original source The combination of OLEDs and acoustic antennas creates a light source that could be used for minimally invasive treatment methods.
Published Researchers develop artificial building blocks of life
(via sciencedaily.com) Original source For the first time, scientists have developed artificial nucleotides, the building blocks of DNA, with several additional properties in the laboratory.
Published A better handle on the emissions budget for the Paris climate targets
(via sciencedaily.com) Original source Scientists have found a new way to calculate the total carbon emissions consistent with the Paris climate targets of 1.5 degrees Celsius and 2 degrees Celsius of global warming.
Published Balancing training data and human knowledge makes AI act more like a scientist
(via sciencedaily.com) Original source When you teach a child how to solve puzzles, you can either let them figure it out through trial and error, or you can guide them with some basic rules and tips. Similarly, incorporating rules and tips into AI training -- such as the laws of physics --could make them more efficient and more reflective of the real world. However, helping the AI assess the value of different rules can be a tricky task.
Published Interstellar signal linked to aliens was actually just a truck
(via sciencedaily.com) Original source Sound waves thought to be from a 2014 meteor fireball north of Papua New Guinea were almost certainly vibrations from a truck rumbling along a nearby road, new research shows. The findings raise doubts that materials pulled last year from the ocean are alien materials from that meteor, as was widely reported.
Published New study reveals insight into which animals are most vulnerable to extinction due to climate change
(via sciencedaily.com) Original source In a new study, researchers have used the fossil record to better understand what factors make animals more vulnerable to extinction from climate change. The results could help to identify species most at risk today from human-driven climate change.
Published Pinging pipes could help to identify lead water lines without excavation
(via sciencedaily.com) Original source A recent study showed that it is possible to discern the composition of a buried pipe by striking an accessible portion of it and monitoring the sound waves that reach the surface. This method could help water utility companies verify the location of lead water lines without having to break ground.
Published Researchers develop new machine learning method for modeling of chemical reactions
(via sciencedaily.com) Original source Researchers have used machine learning to create a model that simulates reactive processes in organic materials and conditions.
Published Microbes impact coral bleaching susceptibility
(via sciencedaily.com) Original source A new study provides insights into the role of microbes and their interaction as drivers of interspecific differences in coral thermal bleaching.
Published Understanding wind and water at the equator key to more accurate future climate projections
(via sciencedaily.com) Original source Getting climate models to mimic real-time observations when it comes to warming is critical -- small discrepancies can lead to misunderstandings about the rate of global warming as the climate changes. A new study that when modeling warming trends in the Pacific Ocean, there is still a missing piece to the modeling puzzle: the effect of wind on ocean currents in the equatorial Pacific.
