Phys.org / On iconic Pikes Peak, climate change is shifting the timing between flowers and pollinators
Warming temperatures and earlier snowmelt are disrupting the long-running relationship between wildflowers and their pollinators on Colorado's Pikes Peak.
Phys.org / Bird's eye view: Study uses aerial imagery to gauge health of city's green roofs
Researchers from the University of Toronto's John H. Daniels Faculty of Architecture, Landscape, and Design have conducted an in-depth analysis of green rooftops in Toronto, providing a framework for future green roof planning ...
Phys.org / Algorithmic outreach can lead to information inequality
Algorithms that identify influential people in social networks can help maximize the reach of messages, but a modeling study published in PNAS Nexus shows that those same algorithms can disseminate information inequitably, ...
Phys.org / Marine microbial competition may offer key to better climate modeling
In the cobalt waters off San Diego, the key to tracking a powerful greenhouse gas drifts just below the surface. Tiny ocean microbes living in oxygen-starved waters turn everyday nutrients into nitrous oxide (N₂O)—a compound ...
Phys.org / The quantum door mystery: Electrons that can't find the exit
What happens when electrons leave a solid material? This seemingly simple phenomenon has, until now, eluded accurate theoretical description. In a new study, researchers have found the missing piece of the puzzle.
Phys.org / New chemical treatment turns deadly arsenic contaminant into a valuable raw material
Arsenic is a natural component of Earth's crust and highly toxic in its inorganic form. The element is a cause of a global public health crisis, as it is present in groundwater and the drinking water consumed daily by millions ...
Phys.org / Distant galaxy A1689-zD1 found to have unusually low dust-to-gas ratio
Using the James Webb Space Telescope (JWST) and the Atacama Large Millimeter/sub-millimeter Array (ALMA), an international team of astronomers has carried out comprehensive multiwavelength observations of a distant massive ...
Phys.org / Hybrid metasurface modulates light at low voltages for energy-efficient optics
Metasurfaces are two-dimensional (2D), nanoengineered surfaces that interact strongly with electromagnetic waves and can control light with remarkable precision. These ultra-thin layers can be used to develop a wide range ...
Phys.org / National study finds public Montessori programs strengthen early learning outcomes—at sharply lower costs
The first national randomized trial of public Montessori preschool students showed stronger long-term outcomes by kindergarten, including elevated reading, memory, and executive function as compared to non-Montessori preschoolers.
Phys.org / What goes up must come down: The 'universal thermal performance curve' that shackles evolution
Scientists from Trinity College Dublin have unearthed a universal thermal performance curve (UTPC) that seemingly applies to all species and dictates their responses to temperature change. This UTPC essentially shackles evolution ...
Phys.org / A mathematical 'Rosetta Stone' translates and predicts the larger effects of molecular systems
Penn Engineers have developed a mathematical "Rosetta Stone" that translates atomic and molecular movements into predictions of larger-scale effects, like proteins unfolding, crystals forming and ice melting, without the ...
Phys.org / Simple stabilizing solution leads to seven new ceramic materials
Sometimes, less really is more. By removing oxygen during synthesis, a team led by materials scientists at Penn State has created seven new high-entropy oxides (HEOS), a class of ceramics composed of five or more metals with ...
