Published How to build greener data centers? Scientists say crank up the heat
(via sciencedaily.com) Original source Colder is not always better for energy-hungry data centers, especially when it comes to their power bills. A new analysis says that keeping the centers at 41°C, or around 105°F, could save up to 56% in cooling costs worldwide. The study proposes new temperature guidelines that may help develop and manage more efficient data centers and IT servers in the future.
Published Subalpine forests in the Northern Rockies are fire resilient--for now
(via sciencedaily.com) Original source Using lake sediment cores, scientists determined how these subalpine ecosystems recovered after 4,800 years of fire.
Published New recipe for efficient, environmentally friendly battery recycling
(via sciencedaily.com) Original source Researchers are now presenting a new and efficient way to recycle metals from spent electric car batteries. The method allows recovery of 100 per cent of the aluminum and 98 per cent of the lithium in electric car batteries. At the same time, the loss of valuable raw materials such as nickel, cobalt and manganese is minimized. No expensive or harmful chemicals are required in the process because the researchers use oxalic acid -- an organic acid that can be found in the plant kingdom.
Published How to help save plants from extinction
(via sciencedaily.com) Original source Now is the time to identify the conditions that cause plants to die. Doing so will allow us to better protect plants by choosing conservation targets more strategically, botanists argue.
Published Ocean circulation, ice melt and increasing tourism could all be contributing to Arctic microplastics
(via sciencedaily.com) Original source Scientists measured microplastic concentrations in the highly productive Barents Sea and suggest that ocean circulation, ice melt, tourism, inadequate waste management, shipping and fishing are all likely contributors.
Published Research finds water quality in Gulf of Mexico improves when adding social costs to carbon emissions
(via sciencedaily.com) Original source Researchers took a closer look at what would happen to agriculture if there was an extra cost, or so-called social cost, added to fossil fuels, which are essential for making fertilizer used in farming. They found that while CO2 emissions would decline by as much as 50%, the cost of fertilizer would rise leading to a significant benefit on water quality by lessening fertilizer runoff contributing to the Gulf of Mexico's dead zone.
Published World may have crossed solar power 'tipping point'
(via sciencedaily.com) Original source The world may have crossed a 'tipping point' that will inevitably make solar power our main source of energy, new research suggests.
Published Decontamination method zaps pollutants from soil
(via sciencedaily.com) Original source A rapid, high-heat electrothermal soil remediation process flushes out both organic pollutants and heavy metals in seconds without damaging soil fertility.
Published Climate network analysis helps pinpoint regions at higher risk of extreme weather
(via sciencedaily.com) Original source Climate change and the rapid increase in frequency of extreme weather events around the globe reinforces the reality that these events are interconnected. Researchers now describe a climate network analysis method to explore the intensity, distribution, and evolution of this interlinked climate behavior, or teleconnections. The analysis combines the directions and distribution patterns of teleconnections to evaluate their intensity and to identify sensitive regions using global daily surface air temperature data. The method relies on advanced data processing and mathematical algorithms to find meaningful insights.
Published Unique marimo threatened by rising lake temperatures
(via sciencedaily.com) Original source Rising lake water temperatures threaten the survival of marimo, unique algal balls found only in cold lakes. Researchers clarified that the warmer it gets, the more the inward decomposition outpaces the outward growth of these life forms, making them increasingly fragile.
Published Signatures of the Space Age: Spacecraft metals left in the wake of humanity's path to the stars
(via sciencedaily.com) Original source Using tools hitched to the nose cone of their research planes and sampling more than 11 miles above the planet's surface, researchers have discovered significant amounts of metals in aerosols in the atmosphere, likely from increasingly frequent launches and returns of spacecraft and satellites. That mass of metal is changing atmospheric chemistry in ways that may impact Earth's atmosphere and ozone layer.
Published Ice sheet surface melt is accelerating in Greenland and slowing in Antarctica
(via sciencedaily.com) Original source Surface ice in Greenland has been melting at an increasing rate in recent decades, while the trend in Antarctica has moved in the opposite direction, according to researchers.
Published Marine bacteria take a bite at plastic pollution
(via sciencedaily.com) Original source A bacterium found in the sea can degrade a plastic that otherwise resists microbial breakdown in marine environments.
Published More sustainable agriculture by global redistribution of nitrogen fertilizer
(via sciencedaily.com) Original source The growing global population needs sufficient food. Its production causes overfertilization and increased nitrogen concentration in agriculture, which negatively affects the population, climate, and ecosystems. According to new models, however, today's crop production might be maintained with a far smaller global fertilizer consumption, if nitrogen fertilizer would be used more homogeneously across global croplands.
Published New study confirms presence of flesh-eating and illness-causing bacteria in Florida's coastal waters following Hurricane Ian
(via sciencedaily.com) Original source When Hurricane Ian struck southwest Florida in September 2022, it unleashed a variety of Vibrio bacteria that can cause illness and death in humans, according to a new study.
Published Climate change coping mechanism discovered in humble algae
(via sciencedaily.com) Original source One of the building blocks of ocean life can adapt to cope with the effects of climate change, according to new research. The discovery holds promises for biotechnology developments that could counter the negative effects of changing environmental conditions, such as ocean warming and even the reduction in the productivity of crops.
Published Wildfires threaten environmental gains in climate-crucial Amazon
(via sciencedaily.com) Original source Despite steps toward decreasing deforestation, uncontrolled wildfires are threatening environmental gains in Brazilian Amazonia, one of the world's most critical carbon sinks and a region of high biological and cultural diversity.
Published Research shows wildfire smoke may linger in homes long after initial blaze
(via sciencedaily.com) Original source Newly published research on indoor air quality shows wildfire smoke may linger in homes long after the initial blaze has been put out or winds have shifted. The findings show that wildfire smoke can attach to home surfaces like carpet, drapes or counters -- extending the exposure for those inside and potentially causing health problems even after an initial cleaning activity by air purifiers.
Published Second report on the status of global water resources published
(via sciencedaily.com) Original source Scientists recently presented a report on the status of global water resources. According to this report, large parts of the world experienced drier conditions in 2022 than those recorded on average for the equivalent periods over the last 30 years.
Published What phytoplankton physiology has to do with global climate
(via sciencedaily.com) Original source Phytoplankton, tiny photosynthetic organisms in the ocean, play a crucial role in the global carbon cycle and influence Earth's climate. A new study reveals how variations in the physiology of phytoplankton, particularly regarding nutrient uptake, can impact the chemical composition of the ocean and even the atmosphere. This suggests that changes in marine phytoplankton physiology can affect global climate.
