Published Could lead overcome reverse current and advance a green hydrogen economy?
(via sciencedaily.com) Original source Researchers developed a catalyst that enhances the stability of alkaline water electrolysis systems.
Published Not so simple: Mosses and ferns offer new hope for crop protection
(via sciencedaily.com) Original source Mosses, liverworts, ferns and algae may offer an exciting new research frontier in the global challenge of protecting crops from the threat of disease.
Published Wolves' return has had only small impact on deer populations in NE Washington
(via sciencedaily.com) Original source Wolves returned to Washington state in 2008. A new study shows that, despite their rising numbers, wolves are not having much of an impact on white-tailed deer, one of their primary prey. Scientists report that the biggest factor shaping white-tailed deer populations in northeast Washington is the quality of habitat available, which is largely determined by human activity. Cougars were second in their impact. Wolves were a distant third.
Published The Gulf Stream is wind-powered and could weaken from climate change
(via sciencedaily.com) Original source New evidence of changes to the Gulf Stream during the last ice age could indicate additional sensitivity to future climatic changes, finds a new study.
Published Tackling the challenge of coca plant ID: Wild vs cultivated for cocaine
(via sciencedaily.com) Original source A new paper reveals that it's not as straightforward as it might seem. Despite decades of data collection by the United Nations Office on Drugs and Crime (UNODC), which has been valuable to monitor changes in areas occupied by illegal coca plantations in South America, there is no reliable scientific method to distinguish between different types of coca plants.
Published Archaeologists report earliest evidence for plant farming in east Africa
(via sciencedaily.com) Original source A trove of ancient plant remains excavated in Kenya helps explain the history of plant farming in equatorial eastern Africa, a region long thought to be important for early farming but where scant evidence from actual physical crops has been previously uncovered.
Published Building materials for water-rich planets in the early solar system
(via sciencedaily.com) Original source Age data for certain classes of meteorite have made it possible to gain new findings on the origin of small water-rich astronomical bodies in the early solar system. These planetesimals continually supplied building materials for planets -- also for the Earth, whose original material contained little water. The Earth received its actual water through planetesimals, which emerged at low temperatures in the outer solar system, as shown by computational models carried out by an international research teach with participation by earth scientists.
Published First local extinction in the US due to sea level rise, study suggests
(via sciencedaily.com) Original source The United States has lost its only stand of the massive Key Largo tree cactus in what researchers believe is the first local extinction of a species caused by sea level rise in the country.
Published How a plant app helps identify the consequences of climate change
(via sciencedaily.com) Original source A research team has developed an algorithm that analyses observational data from a plant identification app. The novel approach can be used to derive ecological patterns that could provide valuable information about the effects of climate change on plants.
Published Ancient large kangaroo moved mainly on four legs, according to new research
(via sciencedaily.com) Original source A type of extinct kangaroo that lived during the Pleistocene around two and a half million to ten thousand years ago, known as the 'giant wallaby', was a poor hopper, a study has found.
Published Study projects major changes in North Atlantic and Arctic marine ecosystems due to climate change
(via sciencedaily.com) Original source New research predicts significant shifts in marine fish communities in the North Atlantic and Arctic Oceans as a result of climate warming.
Published Researcher finds lithium ion batteries a growing source of pollution
(via sciencedaily.com) Original source The use of certain substances in batteries is polluting air and water.
Published Study reveals environmental impact of artificial sweeteners
(via sciencedaily.com) Original source A recently published study demonstrates how sucralose affects the behavior of cyanobacteria -- an aquatic photosynthetic bacteria -- and diatoms, microscopic algae that account for more than 30% of the primary food production in the marine food chain.
Published Restored oyster sanctuaries host more marine life
(via sciencedaily.com) Original source Oysters sanctuaries in Chesapeake Bay are working for more than just oysters. Compared to nearby harvest areas, sanctuaries contain more abundant populations of oysters and other animal life--and the presence of two common parasites isn't preventing that.
Published New extremely fast carbon storage technology
(via sciencedaily.com) Original source A new way to store carbon captured from the atmosphere works much faster than current methods without the harmful chemical accelerants they require.
Published How dust pollution from shrinking Great Salt Lake affects communities disproportionately
(via sciencedaily.com) Original source Exposure to wind-blown dust from exposed playa of the Utah lake is worse in Hispanic neighborhoods, according to new research. Findings suggest restoring the lake could ease social inequities associated with air pollution.
Published Cool roofs are best at beating cities' heat
(via sciencedaily.com) Original source Painting roofs white or covering them with a reflective coating would be more effective at cooling cities like London than vegetation-covered 'green roofs,' street-level vegetation or solar panels, finds a new study led by UCL researchers.
Published A breakthrough in inexpensive, clean, fast-charging batteries
(via sciencedaily.com) Original source Scientists have created an anode-free sodium solid-state battery. This brings the reality of inexpensive, fast-charging, high-capacity batteries for electric vehicles and grid storage closer than ever.
Published Early-onset El Niño means warmer winters in East Asia, and vice versa
(via sciencedaily.com) Original source Researchers have found that the early onset of El Nino around June leads to warm winter climates in Japan, while the late onset of El Nino is associated with colder winters. By analyzing 100-ensemble member climate simulations over the past 61 years, the team found that the warming of the tropical Indian Ocean was a player in warmer Japanese winters.
Published Near chromosome-level genome of the Mojave poppy bee
(via sciencedaily.com) Original source Scientists have developed a near chromosome-level genome for the Mojave poppy bee, a specialist pollinator of conservation concern.
