WVU technology innovations position West Virginia to lead hydrogen economy
West Virginia University engineers have received a wave of federal support for research projects that will help slash the cost of clean hydrogen. The three U.S. Department of Energy grants for WVU studies total $15.8 million and are part of funds authorized by the Bipartisan Infrastructure Law for research that advances the “Hydrogen Shot” goal of cutting the cost of clean hydrogen production to $1 per kilogram.
There May Be Good News About the Oceans in a Globally Warmed World
An analysis of oxygen levels in Earth’s oceans may provide some rare, good news about the health of the seas in a future, globally warmed world.
Decrease Oxygen to Boost Longevity?
Living in a low-oxygen environment extended life spans, preserved neurologic function in mice.
Two meteorites are providing a detailed look into outer space
Meteorites can be used to peek back in time or at the earliest forms of life. Today, scientists report results of the most detailed analyses yet on the organic material of two meteorites. They will present their results at ACS Spring 2023.
Experimentalists: Sorry, no oxygen required to make these minerals on Mars
Scientists at Washington University in St. Louis discovered that under Mars-like conditions, manganese oxides can be readily formed without atmospheric oxygen. The study from the laboratory of Jeffrey Catalano in Arts & Sciences was published Dec. 22 in Nature Geoscience.
World’s Lakes Losing Oxygen Rapidly as Planet Warms
Oxygen levels in the world’s temperate freshwater lakes are declining rapidly — faster than in the oceans — a trend driven largely by climate change that threatens freshwater biodiversity and drinking water quality.
Did Earth’s Early Rise in Oxygen Support The Evolution of Multicellular Life — or Suppress It?
Study offers significant new information on the correlations between oxygenation of the early Earth and the rise of large multicellular organisms. “We show that the effect of oxygen is more complex than previously imagined,” said Will Ratcliff with Georgia Tech’s School of Biological Sciences.
When using pyrite to understand Earth’s ocean and atmosphere: Think local, not global
Scientists have long used information from sediments at the bottom of the ocean to reconstruct the conditions in oceans of the past. But a study in Science Advances raises concerns about the common use of pyrite sulfur isotopes to reconstruct Earth’s evolving oxidation state. These signals aren’t the global fingerprint of oxygen in the atmosphere, according to new research from Washington University in St. Louis.
Rutgers Expert Available to Discuss James Webb Space Telescope Science
New Brunswick, N.J. (Feb. 22, 2021) – Rutgers University–New Brunswick Professor Kristen McQuinn is available for interviews on the upcoming launch of the James Webb Space Telescope, its potential scientific impact and the leap forward it will provide in our understanding of the…
How Did Red Algae Survive in Extreme Environments?
Red algae have persisted in hot springs and surrounding rocks for about 1 billion years. Now, a Rutgers-led team will investigate why these single-celled extremists have thrived in harsh environments – research that could benefit environmental cleanups and the production of biofuels and other products.
How to Get a Handle on Carbon Dioxide Uptake by Plants
How much carbon dioxide, a pivotal greenhouse gas behind global warming, is absorbed by plants on land? It’s a deceptively complicated question, so a Rutgers-led group of scientists recommends combining two cutting-edge tools to help answer the crucial climate change-related question.
Marine animals live where ocean is most ‘breathable,’ but ranges could shrink with climate change
Research shows that many marine animals already inhabit the maximum range of breathable ocean that their physiology allows. The findings are a warning about climate change: Since warmer waters harbor less oxygen, stretches of ocean that are breathable today for a species may not be in the future.
Ocean Algae Get “Coup de Grace” from Viruses
Scientists have long believed that ocean viruses always quickly kill algae, but Rutgers-led research shows they live in harmony with algae and viruses provide a “coup de grace” only when blooms of algae are already stressed and dying. The study, published in the journal Nature Communications, will likely change how scientists view viral infections of algae, also known as phytoplankton – especially the impact of viruses on ecosystem processes like algal bloom formation (and decline) and the cycling of carbon and other chemicals on Earth.
Hubble Uses Earth as a Proxy for Identifying Oxygen on Potentially Habitable Planets Around Other Stars
Astronomers used Hubble during a total lunar eclipse to detect ozone in our planet’s atmosphere by looking at Earthlight reflected off the Moon in ultraviolet wavelengths. This method serves as a proxy for how astronomers will observe Earth-like exoplanets in search of life.
Volcanic activity and changes in Earth’s mantle were key to rise of atmospheric oxygen
Evidence from rocks billions of years old suggest that volcanoes played a key role in the rise of oxygen in the atmosphere of the early Earth.
Solving the mysteries of water and air underground
The mysterious capillary fringe has huge effects on the soil, and new research tells us how it works.
Algae in the Oceans Often Steal Genes from Bacteria
Algae in the oceans often steal genes from bacteria to gain beneficial attributes, such as the ability to tolerate stressful environments or break down carbohydrates for food, according to a Rutgers co-authored study.
The study of 23 species of brown and golden-brown algae, published in the journal Science Advances, shows for the first time that gene acquisition had a significant impact on the evolution of a massive and ancient group of algae and protists (mostly one-celled organisms including protozoa) that help form the base of oceanic food webs.
Hubble Probes Alien Comet’s Chemical Makeup
Zooming through space, the first bonafide interstellar comet discovered passing through our solar system is yielding chemical clues to its origin. An abundance of carbon monoxide contained in comet Borisov suggests it was born around a cool red dwarf star.
Scientists Discover New Clue Behind Age-Related Diseases and Food Spoilage
Berkeley Lab scientists have made a surprising discovery that could help explain our risk for developing chronic diseases or cancers as we get older, and how our food decomposes over time.
Does Lung Damage Speed Pancreatic Cancer?
High levels of CO2 in the body, due to chronic respiratory disorders, may exacerbate pancreatic cancer, making it more aggressive and resistant to therapy.
