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 History repeats as Coral Bay faces mass loss of coral and fish life
(via sciencedaily.com) Original source A perfect storm of environmental factors has seen a monumental loss of fish and coral life at a popular area of Ningaloo Reef in Western Australia's Gascoyne region -- however research into the event shows there is hope it will recover. In March 2022, during the annual coral spawning event, calm weather and limited tidal movement combined to trap the coral's eggs within Bills Bay, at the town of Coral Bay. This led to an excess of nutrients in the water which consumed more oxygen than usual -- causing massive numbers of fish and corals to die from asphyxiation.
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 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 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 Pronghorn population declining due to human development
(via sciencedaily.com) Original source A new article looked at 40 years of data collected on 40 pronghorn herds residing in the Wyoming Basin Shrub Steppe. Overall, 80% of the herds saw a decrease in productivity, and nearly 43% saw a significant decrease. After looking at a number of variables that could potentially contribute to the decline, the researchers identified the two most strongly associated: development of oil and gas resources and woody encroachment.
Published Gene flow in giraffes and what it means for their conservation
(via sciencedaily.com) Original source Giraffes, with their bizarre body plan, have always held a special place in the minds of evolutionary biologists and non-experts alike. In a new study whole-genome sequencing data was used to investigate the evolutionary processes occurring within giraffes. In particular, the authors were interested in establishing whether different populations of giraffes really have been isolated from each other for extended periods of time, which is normally a requirement before new species can arise.
Published Cheetahs' unrivalled speed explained by their 'sweet spot' size, finds Imperial study
(via sciencedaily.com) Original source A new study has answered a long-held question about why medium-sized land animals like cheetahs tend to be fastest.
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 Good news for coral reef restoration efforts: Study finds 'full recovery' of reef growth within four years
(via sciencedaily.com) Original source While the majority of the world's reefs are now under threat or even damaged potentially beyond repair, a new study offers some encouraging news: efforts to restore coral reefs not only increase coral cover, but they can also bring back important ecosystem functions, and surprisingly fast.
Published Reptile roadkill reveals new threat to endangered lizard species
(via sciencedaily.com) Original source The chance sighting of a dead snake beside a sandy track in remote Western Australia, and the investigation of its stomach contents, has led researchers to record the first known instance of a spotted mulga snake consuming a pygmy spiny-tailed skink, raising concerns for a similar-looking, endangered lizard species.
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.
