Published Searching for life with space dust
(via sciencedaily.com) Following enormous collisions, such as asteroid impacts, some amount of material from an impacted world may be ejected into space. This material can travel vast distances and for extremely long periods of time. In theory this material could contain direct or indirect signs of life from the host world, such as fossils of microorganisms. And this material could be detectable by humans in the near future, or even now.
Published Hunting Venus 2.0: Scientists sharpen their sights
(via sciencedaily.com) With the first paper compiling all known information about planets like Venus beyond our solar system, scientists are the closest they've ever been to finding an analog of Earth's 'twin.'
Published Synthesis gas and battery power from sunlight energy
(via sciencedaily.com) Plants use photosynthesis to harvest energy from sunlight. Now researchers have applied this principle as the basis for developing new sustainable processes which in the future may produce syngas (synthetic gas) for the large-scale chemical industry and be able to charge batteries.
Published Human and ocean health impacts of ocean plastics
(via sciencedaily.com) Researchers from the fields of healthcare, ocean science, and social science have collaborated to quantify plastic's considerable risks to all life on Earth. The Minderoo-Monaco Commission on Plastics and Human Health report presents a comprehensive analysis showing plastics as a hazard at every stage of their life cycle.
Published Solar industry feeling the heat over disposal of 80 million panels
(via sciencedaily.com) Renewable energy experts have come up with an environmentally-friendly plan to dispose of solar panels at the end of their life.
Published 3000+ billion tons of ice lost from Antarctic Ice Sheet over 25 years
(via sciencedaily.com) Original source Scientists have calculated that the fastest changing Antarctic region?-?the Amundsen Sea Embayment?-?has lost more than 3,000 billion tonnes of ice over a 25-year?period.??
Published 'Rock stars' solve long-standing diamond conundrum
(via sciencedaily.com) Two researchers have used a standard laptop computer and a humble piece of rock -- from the 'waste pile' of a diamond mine -- to solve a long-held geological conundrum about how diamonds formed in the deep roots of the earth's ancient continents.
Published Lower energy consumption thanks to daylight-saving time
(via sciencedaily.com) Original source The elimination of daylight-saving time is a frequently -- and heatedly -- discussed topic. Often, only the aspect of electricity consumption due to artificial lighting is considered. In a new study, researchers have now analyzed whether daylight saving also has an impact on the heating and cooling energy required for office buildings, and what role climate change might play in this. The results should delight supporters of daylight-saving time.
Published Galaxy changes classification as jet changes direction
(via sciencedaily.com) A team of international astronomers have discovered a galaxy that has changed classification due to unique activity within its core. The galaxy, named PBC J2333.9-2343, was previously classified as a radio galaxy, but the new research has revealed otherwise.
Published Forest growing season in eastern U.S. has increased by a month
(via sciencedaily.com) The growing period of hardwood forests in eastern North America has increased by an average of one month over the past century as temperatures have steadily risen, a new study has found.
Published Public acceptance of fossil fuel subsidy removal could be improved in developing countries
(via sciencedaily.com) People might be more positive to the removal of fuel subsidies if told where the money would be spent instead. This has been shown in a study which investigated attitudes towards removing fossil fuel subsidies in five developing countries.
Published Nitrate can release uranium into groundwater
(via sciencedaily.com) A team has experimentally confirmed that nitrate, a compound common in fertilizers and animal waste, can help transport naturally occurring uranium from the underground to groundwater. The new research backs a previous study showing that aquifers contaminated with high levels of nitrate -- including the High Plains Aquifer residing beneath Nebraska -- also contain uranium concentrations far exceeding a threshold set by the Environmental Protection Agency. Uranium concentrations above that EPA threshold have been shown to cause kidney damage in humans, especially when regularly consumed via drinking water.
Published Scientists find a common thread linking subatomic color glass condensate and massive black holes
(via sciencedaily.com) Atomic nuclei accelerated close to the speed of light become dense walls of gluons known as color glass condensate (CGC). Recent analysis shows that CGC shares features with black holes, enormous conglomerates of gravitons that exert gravitational force across the universe. Both gluons in CGC and gravitons in black holes are organized in the most efficient manner possible for each system's energy and size.
Published Defunding prevention and climate change drive rebound of malaria in Peru
(via sciencedaily.com) Malaria control programs in Amazonian Peru helped reduce the incidence of the deadly parasitic disease by 78 percent. That is, until the programs ceased to operate. Within four years of the programs being de-funded, malaria rates where right back where they started. The rebound was driven not only by the removal of prevention programs, but also by climate change. Average temperatures in Peru have risen a half-degree Centigrade in the last 20 years.
Published Biodiversity amid climate change
(via sciencedaily.com) Fewer parasites in U.S. waters might be seen by many as a good thing, but a biologist says the trend signals potential danger for fish and other wildlife.
Published In hot water: Ocean warming impacts growth, metabolic rate and gene activity of newly hatched clownfish
(via sciencedaily.com) Future ocean warming and marine heatwaves could impact the growth and development of clownfish during their earliest life stages, suggests a new study.
Published Stressed out: Mapping the human footprint on coastal areas globally
(via sciencedaily.com) A global mapping project has revealed the major stressors placed upon global coastlines by human activity.
Published Mountain forests are being lost at an accelerating rate, putting biodiversity at risk
(via sciencedaily.com) More than 85% of the world's bird, mammal, and amphibian species live in mountains, particularly in forest habitats, but researchers report that these forests are disappearing at an accelerating rate. Globally, we have lost 78.1 million hectares (7.1%) of mountain forest since 2000 -- an area larger than the size of Texas. Much of the loss occurred in tropical biodiversity hotspots, putting increasing pressure on threatened species.
Published New study counts the environmental cost of managing Japanese knotweed
(via sciencedaily.com) New research has looked at the long-term environmental impact of different methods to control Japanese knotweed. Different ways of trying to control the invasive species have developed over the years but now, as sustainability becomes increasingly important, understanding the effect of these management methods is vital.This new study examines at the entire life cycle and long-term impacts of different management approaches.
Published How can we tackle the biggest challenges? Ask a plant
(via sciencedaily.com) Without plants, we'd have no air to breathe or food to eat, yet plant science lingers in the shadowy wings while other fields take center stage. With the goal of shining the spotlight on plants, a new study presents the field's top 100 most pressing questions for research to address the greatest challenges facing humanity.
