Published Heat tolerant coral may trade fast growth for resilience
(via sciencedaily.com) Original source Algae living within the soft tissue of coral supply much of the energy needed by their hosts, and some symbiotic algae help coral withstand warmer water better than others. Researchers have now found that there was a tradeoff for corals dominated by the thermally sensitive algae -- they have higher growth, but only in cooler water.
Published Research in Lake Superior reveals how sulfur might have cycled in Earth's ancient oceans
(via sciencedaily.com) Original source A scientists has sulfur on her mind. The yellow element is a vital macronutrient, and she's trying to understand how it cycles through the environment. Specifically, she's curious about the sulfur cycle in Earth's ancient ocean, some 3 billion years ago.
Published Temperature variability reduces nesting success
(via sciencedaily.com) Original source Many songbirds are nesting earlier in spring because of warmer temperatures brought about by climate change. But the shift brings another danger that is especially deadly for nestlings: greater exposure to temperature variability in the form of cold snaps and heat waves.
Published New study reveals huge potential for future waves of invasive species
(via sciencedaily.com) Original source Human trade and transport have led to the intentional and accidental introductions of non-native species outside of their natural range globally. These biological invasions can cause extinctions, cost trillions, and spread diseases. A study has investigated how many of these non-native species already exist worldwide and which species groups are particularly prone to become non-native.
Published WhaleVis turns more than a century of whaling data into an interactive map
(via sciencedaily.com) Original source A team has created an interactive dashboard called WhaleVis, which lets users map data on global whale catches and whaling routes from 1880 to 1986. Scientists can compare this historical data and its trends with current information to better understand whale populations over time.
Published Ice cores from Earth's highest tropical peak provide insight into climate variability
(via sciencedaily.com) Original source A new study examines ice cores from the summit of the highest tropical mountain in the world, and finds unique insight into the climate record of the Amazon Basin over the last six decades.
Published Surveilling wetlands for infectious bird flu -- and finding it
(via sciencedaily.com) Original source Recently, morning omelets and holiday dinners have gotten more expensive. One likely cause is bird flu, outbreaks of which led to the deaths of millions of chickens and turkeys from infection or culling in 2022, according to the U.S. Department of Agriculture, and which still demands rigorous monitoring of wild populations. Now, researchers have developed a method that detected infectious bird flu virus in wetlands frequented by waterfowl.
Published Climate engineering could slow Antarctic ice loss, study suggests
(via sciencedaily.com) Original source A study reports that scattering sunlight-reflecting particles in the atmosphere -- a theoretical form of climate engineering known as 'stratospheric aerosol injection' -- has potential to slow rapid ice melt in Western Antarctica.
Published Not so silver lining: Microplastics found in clouds could affect the weather
(via sciencedaily.com) Original source From the depths of the seas to snow on mountains and even the air above cities, microplastics are turning up increasingly often. Now, researchers have analyzed microplastics in clouds above mountains. They suggest that these tiny particles could play a role in cloud formation and, in turn, affect weather.
Published Previously unknown luminescence revealed in ten deep sea species and an order of sea cucumbers
(via sciencedaily.com) Original source Researchers present evidence of previously unknown luminosity in 10 deep-sea species, suggesting underestimated diversity. These new discoveries include a member of the order Molpadia, which was previously thought not to be luminescent. The authors stress the importance of considering the ecological role of bioluminesence and the need for conservation.
Published 'Bouncing' comets could deliver building blocks for life to exoplanets
(via sciencedaily.com) Original source How did the molecular building blocks for life end up on Earth? One long-standing theory is that they could have been delivered by comets. Now, researchers have shown how comets could deposit similar building blocks to other planets in the galaxy.
Published Study sheds light on how Earth cycles fossil-carbon
(via sciencedaily.com) Original source Researches used rhenium as a proxy for fossil carbon in order to quantify the rate at which Earth naturally releases carbon dioxide into the atmosphere and found that high rates of carbon breakdown persist across the different geographical profiles of a river basin.
Published Earth's surface water dives deep, transforming core's outer layer
(via sciencedaily.com) Original source A new study has revealed that water from the Earth's surface can penetrate deep into the planet, altering the composition of the outermost region of the metallic liquid core and creating a distinct, thin layer. Illustration of silica crystals coming out from the liquid metal of the Earth's outer core due to a water-induced chemical reaction.
Published Faster Arctic warming hastens 2C rise by eight years
(via sciencedaily.com) Original source The Arctic is currently warming nearly four times faster than the global average rate. The new study aimed to estimate the impact of this faster warming on how quickly the global temperature thresholds of 1.5C and 2C, set down in the Paris Agreement, are likely to be breached.
Published 'Cooling glass' blasts building heat into space
(via sciencedaily.com) Original source Researchers aiming to combat rising global temperatures have developed a new 'cooling glass' that can turn down the heat indoors without electricity by drawing on the cold depths of space. The new technology, a microporous glass coating, can lower the temperature of the material beneath it by 3.5 degrees Celsius at noon, and has the potential to reduce a mid-rise apartment building's yearly carbon emissions by 10 percent.
Published Some of today's earthquakes may be aftershocks from quakes in the 1800s
(via sciencedaily.com) Original source In the 1800s, some of the strongest earthquakes in recorded U.S. history struck North America's continental interior. Almost two centuries later, the central and eastern United States may still be experiencing aftershocks from those events, a new study finds.
Published How climate change could be affecting your brain
(via sciencedaily.com) Original source A new element of the catastrophic impacts of climate change is emerging -- how global warming is impacting the human brain.
Published Wildfire, drought cause $11.2 billion in damage to private timberland in three Pacific states, study finds
(via sciencedaily.com) Original source Wildfires and drought have led to $11.2 billion in damages to privately held timberland in California, Oregon and Washington over the past two decades, a new Oregon State University study found.
Published Aerosols: When scents influence our climate
(via sciencedaily.com) Original source Tiny particles that form from molecules in the air play an important role for climate change. But until now, the have been poorly understood. Scientists have now analyzed how these particles form.
Published Diverse forests hold huge carbon potential, as long as we cut emissions
(via sciencedaily.com) Original source New study estimates that natural forest recovery could capture approximately 226 Gigatonnes (Gt) of carbon, but only if we also reduce greenhouse gas emissions. Achieving these results requires community-driven efforts to conserve and restore biodiversity. In brief: Forests have the potential to capture 226 Gigatonnes (Gt) of carbon in areas where they would naturally exist. This forest potential can only be achieved alongside emissions cuts. Sixty-one percent of the forest potential can be achieved by protecting existing forests and allowing them to regrow to maturity. Thirty-nine percent can be achieved by reconnecting fragmented landscapes through community-driven ecosystem restoration and management. A natural diversity of species is needed to maximize the forest carbon potential.
