Published Mars attracts: How Earth's interactions with the red planet drive deep-sea circulation
(via sciencedaily.com) Original source Scientists have used the geological record of the deep sea to discover a connection between the orbits of Earth and Mars, past global warming patterns and the speeding up of deep ocean circulation. The patterns they discover suggest that warming seas could produce deep whirpools in ocean currents.
Published Rainforest's next generation of trees threatened 30 years after logging
(via sciencedaily.com) Original source Rainforest seedlings are more likely to survive in natural forests than in places where logging has happened -- even if tree restoration projects have taken place, new research shows.
Published Scientists propose new theory that explains sand ripples on Mars and on Earth
(via sciencedaily.com) Original source Sand ripples are symmetrical. Yet wind -- which causes them -- is very much not. Furthermore, sand ripples can be found on Mars and on Earth. They would be even more fascinating if the same effect found on Mars could be found here on Earth as well. What if one unified theory could explain their formation on both planets?
Published Climate policies to reduce motor vehicle emissions can improve children's health, save money
(via sciencedaily.com) Original source A new study finds that policies to reduce carbon dioxide (CO2) emissions from motor vehicles combined with investments in electric vehicles and public transportation would reduce air pollution and bring large benefits to children's health. They would also save money.
Published India's water problems set to get worse as the world warms
(via sciencedaily.com) Original source Winter storms known as western disturbances that provide crucial snow and rainfall to northern India are arriving significantly later in the year.
Published New study reveals transgenerational effects of pesticide linuron on frogs
(via sciencedaily.com) Original source Grand-offspring of male frogs exposed to the pesticide linuron exhibited changes in their DNA that was linked to significant physiological impacts, a study reveals. The research highlights the profound transgenerational consequences of environmental pollution on amphibian populations, which are already under threat of extinction.
Published Study explores impacts of Arctic warming on daily weather patterns in the U.S.
(via sciencedaily.com) Original source Arctic sea ice is shrinking as the world continues to warm, and a new study may provide a better understanding of how the loss of this ice may impact daily weather in the middle latitudes, like the United States.
Published Halloween toy among plastics swallowed by sea turtles
(via sciencedaily.com) Original source A Halloween toy was among hundreds of plastic items found in the guts of dead sea turtles in the Mediterranean, a new study reveals.
Published Mapping the future's sweet spot for clean energy and biodiversity
(via sciencedaily.com) Original source A new study of Joshua trees, kit foxes and solar energy developments highlights the need to consider climate-induced range shifts for species as we expand clean energy.
Published A better handle on the emissions budget for the Paris climate targets
(via sciencedaily.com) Original source Scientists have found a new way to calculate the total carbon emissions consistent with the Paris climate targets of 1.5 degrees Celsius and 2 degrees Celsius of global warming.
Published CSI in space: Analyzing bloodstain patterns in microgravity
(via sciencedaily.com) Original source As more people seek to go where no man has gone before, researchers are exploring how forensic science can be adapted to extraterrestrial environments. A new study highlights the behavior of blood in microgravity and the unique challenges of bloodstain pattern analysis aboard spacecraft.
Published Interstellar signal linked to aliens was actually just a truck
(via sciencedaily.com) Original source Sound waves thought to be from a 2014 meteor fireball north of Papua New Guinea were almost certainly vibrations from a truck rumbling along a nearby road, new research shows. The findings raise doubts that materials pulled last year from the ocean are alien materials from that meteor, as was widely reported.
Published New study reveals insight into which animals are most vulnerable to extinction due to climate change
(via sciencedaily.com) Original source In a new study, researchers have used the fossil record to better understand what factors make animals more vulnerable to extinction from climate change. The results could help to identify species most at risk today from human-driven climate change.
Published Rock weathering and climate: Low-relief mountain ranges are largest carbon sinks
(via sciencedaily.com) Original source For many hundreds of millions of years, the average temperature at the surface of the Earth has varied by not much more than 20 degrees Celsius, facilitating life on our planet. To maintain such stable temperatures, Earth appears to have a 'thermostat' that regulates the concentration of atmospheric carbon dioxide over geological timescales, influencing global temperatures. The erosion and weathering of rocks are important parts of this 'thermostat.'
Published Loss of nature costs more than previously estimated
(via sciencedaily.com) Original source Researchers propose that governments apply a new method for calculating the benefits that arise from conserving biodiversity and nature for future generations.
Published Airflow dynamics scrub classroom air
(via sciencedaily.com) Original source Accounting for airflow dynamics rather than just airflow volume helped researchers measure an 85% reduction in airborne pathogens inside a working classroom.
Published Microbes impact coral bleaching susceptibility
(via sciencedaily.com) Original source A new study provides insights into the role of microbes and their interaction as drivers of interspecific differences in coral thermal bleaching.
Published Understanding wind and water at the equator key to more accurate future climate projections
(via sciencedaily.com) Original source Getting climate models to mimic real-time observations when it comes to warming is critical -- small discrepancies can lead to misunderstandings about the rate of global warming as the climate changes. A new study that when modeling warming trends in the Pacific Ocean, there is still a missing piece to the modeling puzzle: the effect of wind on ocean currents in the equatorial Pacific.
Published Micro- and nanoplastics in the body are passed on during cell division
(via sciencedaily.com) Original source The gastrointestinal tract is already known to researchers as a major storage site for micro- and nanoplastic particles (MNPs) in the human body. A research consortium has now investigated the effects of the tiny plastic particles on cancer cells in the human gastrointestinal tract. The study showed that MNPs remain in the cell for much longer than previously assumed, as they are passed on to the newly formed cell during cell division. The first indications were also discovered that the plastic particles could promote the metastasis of tumors.
Published Viscose manufactured solely from recycled materials
(via sciencedaily.com) Original source At present, viscose textiles are made of biomass from the forest, and there is no such thing as fully recycled viscose. Researchers have now succeeded in making new viscose -- from worn-out cotton sheets.
