Impact of pollutants on pollinators, and how neural circuits adapt to temperature changes

The Kavli Foundation and the U.S. National Science Foundation are collaborating to accelerate research in the emerging field of neurobiology in changing ecosystems. Awardees of the first Kavli-NSF grants will study the impact of atmospheric pollutants on the sense of smell in pollinators, and how neural circuits adapt to changes in temperature.

As Temperatures Rise, Researchers Identify Mechanisms Behind Plant Response to Warming

Plants widen microscopic pores on their leaves in response to heat. But scientists lacked an understanding of the mechanisms behind this “sweating” function. Now, biologists have unlocked the details behind these processes and identified two paths that plants use to handle rising temperatures.

Northern Adriatic: collapse of predator-prey relationships from the 1950s onwards

Predatory snails drill holes in the shells of their prey. Using these boreholes, a research team led by palaeontologist Martin Zuschin from the University of Vienna was able to create a time series of predator-prey relationships in the northern Adriatic over the past millennia. This showed that human influences led to a collapse in predator-prey relationships from the 1950s onwards.

Dengue Fever Lands in LA: How Global Warming Is Affecting Health

Amid southern california’s recent record-breaking heat wave and fast-moving wildfires, public health officials reported the third locally acquired case of dengue fever in the los angeles area. Although the events seem unrelated, they actually are connected—and for troubling reasons.

Hurricanes Cooking up an Intense Season

The onset of the hurricane season has brought renewed attention to the impacts and preparedness efforts necessary to mitigate the damage caused by these powerful storms. The increasing intensity and frequency of hurricanes are attributed to global warming and climate change, posing significant risks to lives, property, and economies.

Charging infrastructure planning for transportation electrification in India: A review

Abstract Global warming and depletion of fossil fuel are the major drivers that initiated the transition from conventional internal combustion engines to electric transportation. India has already embraced the policies and methodologies needed to decarbonize its transportation sector. In this…

Mineralizing emissions: advanced reactor designs for CO2 capture

In an advancing sustainable waste management and CO2 sequestration, researchers have crafted reactors that mineralize carbon dioxide with fly ash particles. This avant-garde technique is set to offer a sustainable and lasting solution to the pressing issue of greenhouse gas emissions, repurposing an industrial by-product in the process.

Carbon Dioxide, the Main Culprit of Global Warming, Reborn as an Antioxidant Substance

The Korea Institute of Energy Research develops a process to convert carbon dioxide into the antioxidant carotenoids using microorganisms. By using a carbon dioxide absorbent, the problem of low solubility is resolved, and the productivity of high-value substances is also improved. Published in the world-renowned journal in the field of chemistry, ‘ChemSusChem

Warming of Antarctic deep-sea waters contribute to sea level rise in North Atlantic, study finds

A new study published in the journal Nature Geoscience led by scientists at University of Miami Rosenstiel School of Marine, Atmospheric, and Earth Science, and the National Oceanic and Atmospheric Administration’s Atlantic Oceanographic and Meteorological Laboratory, found that human-induced environmental changes around Antarctica…

UMass Amherst scientists propose new method for tracking elusive origins of CO2 emissions from streams

A team of researchers from the University of Massachusetts Amherst that specializes in accounting for the carbon dioxide release by streams, rivers and lakes recently demonstrated that the chemical process known as “carbonate buffering” can account for the majority of emissions in highly alkaline waters.

Extreme Weather as the New Norm: American University Experts Available for Comment

WHAT: As scientists, policymakers and communities continue to grapple with extreme weather events and a changing climate, American University experts are available to comment on a wide range of topics and ramifications. WHEN/WHERE: August 30, 2023 – ongoing; availability in-studio, through email, phone or Zoom WHO: Paul Bledsoe is an adjunct professorial lecturer at the Center for Environmental Policy in AU’s School of Public Affairs.

Researchers Find Global Plant Water Use Efficiency Stalled Due to Climate Change

Researchers at the University of New Hampshire have found that water use efficiency has stalled since 2001 which implies not as much CO2 was being taken in by plants and more water was consumed and that could have implications on carbon cycling, agricultural production and water resources.

Sea ice melt, warming ocean temperatures and emergency response: Experts discuss the return of El Niño

The University of Delaware boasts several experts who can talk about El Niño’s return and its wide-reaching impacts, from record-breaking temperatures to sea ice melt that has been shattering scientists’ expectations.  Wei-Jun Cai: Air-sea CO2 flux; carbon cycling in estuaries…

Affordable and available technologies can curb rising nitrous oxide emissions

Researchers from IIASA and the University of Maryland have found that nitrous oxide, a potent greenhouse gas and stratospheric ozone-depleting substance, could be readily abated with existing technology applied to industrial sources.

Climate Change Threatens Military Readiness

The growing frequency and intensity of heat waves around the globe pose “a substantial, persistent ‘non-combat threat’” to military training and operations, according to experts in environmental, thermoregulatory and cardiovascular physiology.

New Research Suggests Wheat Crops May Be Threatened by Unprecedented Heat and Drought

A recent study led by a researcher at the Friedman School of Nutrition Science and Policy at Tufts University found that the likelihood of extreme temperatures that could affect crop yields has increased significantly in wheat-producing regions of the U.S. and China.

Marine Seagrass Meadows Show Resilience to ‘Bounce Back’ After Die-Offs

A study in Florida Bay, one of the largest global contiguous seagrass systems, examined if a phytotoxin that accumulates as seagrass ecosystems become more enriched in nutrients prevents a marine seagrass, turtlegrass, from recruiting into open bare sediment following die-off events. While they do “bounce back,” long-term monitoring indicates the timeframe for recovery after major die-off events is at least a decade. Turtlegrass can successfully recruit into open bare sediment following die-off events due to biomass partitioning.

A Day and Night Difference: Molecular Composition of Aerosols Differs from Day to Night

Aerosols particles in the atmosphere are an important factor in the Earth’s climate, but researchers lack information on these aerosols’ molecular composition, especially for aerosols during the day and night above agricultural fields. In this research, scientists examined secondary organic aerosols over agricultural fields in the Southern Great Plains in Oklahoma. They found that the aerosols’ composition and structure differ from day to night and that some aerosols are ultimately from urban sources.

Costs of Natural Disasters Set To Spiral with Continued Rise in CO2 and Global Temperature, Study Shows

Researchers estimated that climate change-related natural disasters have increased since 1980 and have already cost the United States more than $2 trillion in recovery costs. Their analysis also suggests that as atmospheric carbon dioxide levels and the global temperature continue to rise, the frequency and severity of disasters will increase, with recovery costs potentially rising exponentially.
