Researchers turned to glass beads to produce an environmentally compatible, sustained-release fertilizer. Agricultural fertilizers are critical for feeding the world’s population, restoring soil fertility and sustaining crops. Excessive and inefficient use of those resources can present an environmental threat, contaminating waterways and generating greenhouse gases such as nitrous oxide. Now, researchers reporting in ACS Agricultural Science & Technology have addressed those [...]

Newswise — Regular aerobic exercise could significantly reduce disease markers associated with Alzheimer’s, new research led by scientists at the University of Bristol (UK) and the Federal University of São Paulo (Brazil) has found. The findings provide new hope in the battle against this devastating disorder. Published in the journal Brain Research, the study highlights how physical activity not only protects healthy brain cells but also restores balance in the aging [...]

Newswise — Craniofacial bone defects, resulting from trauma, congenital conditions, or surgical interventions, represent a major challenge in reconstructive surgery. While autogenous grafts are a common solution, they are often constrained by donor site morbidity and limited availability. These drawbacks have sparked a drive to develop synthetic grafts that closely mimic the complex structure and function of natural bone. The rise of advanced bioceramic materials, combined with additive [...]

Newswise — Some children with profound autism experience lifelong difficulties with social, language and cognitive skills, and even lack the ability to speak. Others experience more mild symptoms that improve with time. The disparity in outcomes has been a mystery to scientists, until now. A new study, published in Molecular Autism by researchers at University of California San Diego, is the first to shed light on the matter. Among its findings: The biological basis for these two [...]

Imaging the hot turbulence of aircraft propulsion systems may now be possible with sturdy sheets of composite materials that twist light beams, according to research led by the University of Michigan and Air Force Research Laboratory. The sheets were produced with a new manufacturing method that opens possibilities beyond aircraft design, as it enables new classes of materials to be used in polarization optics. While the team demonstrated high temperature tolerance, new mechanical, [...]

Particles that gum up the keys that the virus uses to enter cells could one day be an effective COVID treatment whenever vaccines and other treatments fall short

Newswise — The Amazon rainforest could approach a tipping point, which could lead to a large-scale collapse with serious implications for the global climate system. A new Nature study by an international research team including scientists from the Potsdam Institute for Climate Impact research (PIK) reveals that up to 47 percent of the Amazonian forest is threatened and identifies climatic and land-use thresholds that should not be breached to keep the Amazon resilient. “The [...]

Global warming may be interacting with regional rainfall and deforestation to accelerate forest loss in the Amazon, pushing it towards partial or total collapse. Research published on 14 February 2024 in Nature , has identified the potential thresholds of these stressors, showing where their combined effects could produce a ‘tipping point' – in which the forest is so fragile that just a small disturbance could cause an abrupt shift in the state of the ecosystem. The study [...]
