Colorful connection found in coral’s ability to survive higher temperatures

(Okinawa Institute of Science and Technology (OIST) Graduate University) A coral’s color can tell of its resilience to climate change, and a new study from the Okinawa Institute of Science and Technology Graduate University has shed light on the underlying genetic factors that may be at work behind this.

Study reveals energy sources supporting coral reef predators

(Newcastle University) Since Charles Darwin’s day, the abundance of life on coral reefs has been puzzling, given that most oceanic surface waters in the tropics are low in nutrients and unproductive. But now research, led by Newcastle University and published in in the journal Science Advances, has confirmed that the food web of a coral reef in the Maldives relies heavily on what comes in from the open ocean.

Biosensors monitor plant well-being in real time

(Linköping University) Researchers at Linköping University, Sweden, have developed biosensors that make it possible to monitor sugar levels in real time deep in the plant tissues – something that has previously been impossible. The information from the sensors may help agriculture to adapt production as the world faces climate change. The results have been published in the scientific journal iScience.

Under Trump, Americans Breathed The Cleanest Air In U.S. History

During his first two days “unifying” the nation, President Joseph R. Biden delivered for the most radical environmental interests of the Democrat coalition that nominated and elected him. After all, that is what he promised to do. Killing the Keystone…

A new modifier increases the efficiency of perovskite solar cells

(National University of Science and Technology MISIS) The research team of NUST MISIS has presented an improved structure of perovskite solar cells. Scientists have modified perovskite-based solar cells using MXenes — thin two-dimensional titanium carbides with high electrical conductivity. The MXenes-based modified cells showed superior performance, with power conversion efficiency exceeding 19% (the reference demonstrated 17%) and improved stabilized power output with respect to reference devices. The results have been published in the Nano energy international scientific journal.

Tourism mainly responsible for marine litter on Mediterranean beaches

(Universitat Autonoma de Barcelona) A study by the ICTA-UAB warns that tourism generates 80% of the marine litter accumulating on the beaches of the Mediterranean islands in summer.For researchers, the global COVID19 pandemic may be an opportunity to rethink the model of sustainable tourism.

Silicon anode structure generates new potential for lithium-ion batteries

(Okinawa Institute of Science and Technology (OIST) Graduate University) New research has identified a nanostructure that improves the anode in lithium-ion batteries. Instead of using graphite for the anode, the researchers turned to silicon: a material that stores more charge but is susceptible to fracturing. The team deposited silicon atoms on top of metallic nanoparticles to form an arched nanostructure, increasing the strength and structural integrity of the anode. Electrochemical tests showed the batteries had a higher charge capacity and longer lifespan.

Healthy oceans need healthy soundscapes

(University of California – Santa Barbara) Rain falls lightly on the ocean’s surface. Marine mammals chirp and squeal as they swim along. The pounding of surf along a distant shoreline heaves and thumps with metronomic regularity. These are the sounds that most of us associate with the marine environment. But the soundtrack of the healthy ocean no longer reflects the acoustic environment of today’s ocean, plagued with human-created noise.

Packing more juice in lithium-ion batteries through silicon anodes and polymeric coatings

(Japan Advanced Institute of Science and Technology) Although silicon anodes could greatly boost the capacity of Li-ion batteries, their performance rapidly degrades with use. Polymeric coatings can help solve this problem, but very few studies have explored the underlying mechanisms. In a recent study, scientists from Japan Advanced Institute of Science and Technology investigate how a poly(borosiloxane) coating greatly stabilizes the capacity of silicon anodes, paving the way for better and more durable Li-ion batteries for electric cars and renewable energy harvesting.

Establishment testing standards for particulate photocatalysts in solar fuel production proposed

(Dalian Institute of Chemical Physics, Chinese Academy Sciences) Recently, an international research team initiated the establishment of international efficiency accreditation and testing protocols for particulate photocatalysts toward solar fuel production.
