Published Vehicle brakes produce charged particles that may harm public health
(via sciencedaily.com) Original source Scientists know relatively little about particles released into the air when a vehicle driver brakes, though evidence suggests those particles may be more harmful to health than particles exiting the tailpipe.
Published AI making waves in marine data collection
(via sciencedaily.com) Original source Numerous measurement stations around the world provide us with data about air quality, allowing us to enhance it. Although we are increasingly collecting data from marine areas, access to such data is considerably more challenging. Signals are poorly transmitted through water, differences in both pressure and currents hinder measurement devices and there is an absence of pre-constructed computing infrastructure. Could intelligent technologies help us improve marine data collection?
Published How a natural compound from sea squirts combats cancer
(via sciencedaily.com) Original source Trabectedin, a promising drug derived from the sea squirt Ecteinascidia turbinata, has shown potential in combating cancers resistant to conventional treatments. However, its precise mechanism of action has remained elusive -- until now.
Published Air filters and scheduled window opening can reduce classroom pollution by up to 36%
(via sciencedaily.com) Original source To improve air quality in classrooms, schools should use air purifiers during the school day and open the windows after hours. That's according to a new study.
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 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 Researchers uncover protein responsible for cold sensation
(via sciencedaily.com) Original source Researchers have identified the protein that enables mammals to sense cold, filling a long-standing knowledge gap in the field of sensory biology.
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 Research sheds light on new strategy to treat infertility
(via sciencedaily.com) Original source New research describes the science behind a promising technique to treat infertility by turning a skin cell into an egg that is capable of producing viable embryos. The technique could be used by women of advanced maternal age or for those who are unable to produce viable eggs due to previous treatment for cancer or other causes. It also raises the possibility of men in same-sex relationships having children who are genetically related to both parents.
Published New study discovers how altered protein folding drives multicellular evolution
(via sciencedaily.com) Original source Researchers have discovered a mechanism steering the evolution of multicellular life. They identified how altered protein folding drives multicellular evolution.
Published Mutation solves a century-old mystery in meiosis
(via sciencedaily.com) Original source A team deciphers complicated mechanism underlying genetic diversity.
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 Researchers develop artificial building blocks of life
(via sciencedaily.com) Original source For the first time, scientists have developed artificial nucleotides, the building blocks of DNA, with several additional properties in the laboratory.
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 Vitamin A may play a central role in stem cell biology and wound repair
(via sciencedaily.com) Original source Retinoic acid, the active state of Vitamin A, appears to regulate how stem cells enter and exit a transient state central to their role in wound repair.
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 How does a virus hijack insect sperm to control disease vectors and pests?
(via sciencedaily.com) Original source A widespread bacteria called Wolbachia and a virus that it carries can cause sterility in male insects by hijacking their sperm, preventing them from fertilizing eggs of females that do not have the same combination of bacteria and virus. A new study has uncovered how this microbial combination manipulates sperm, which could lead to refined techniques to control populations of agricultural pests and insects that carry diseases like Zika and dengue to humans.
