First global map of cargo ship pollution reveals effects of fuel regulations
- ScienceDaily
- 22/8/2 23:58
A new study used satellite data from 2003 -- 2020 to determine the effect of fuel regulations on pollution from cargo ships. The research team's data revealed significant changes in sulfur pollution after regulations went into effect in 2015 and 2020. Their extensive data set can also help scientists determine the extent of the cooling effect of particulate matter when it interacts with clouds....
Why are some birds more intelligent than others?
- ScienceDaily
- 22/8/2 23:58
If you've ever seen a grackle steal your dog pellets or a starling peck open a garbage bag, you get a sense of that some birds have learned to take advantage of new feeding opportunities -- a clear sign of their intelligence. Scientists have long wondered why certain species of birds are more innovative than others, and whether these capacities stem from larger brains (which intuitively seems...
With innovative bioreactor as womb, mouse stem cells transform into organ-filled embryos
What happens in embryonic development is one of nature’s best guarded secrets, unfolding deep in the mother’s body. Now, researchers have opened a new window on the process. They’ve made artificial mouse embryos from stem cells—no sperm or eggs required—and used an innovative bioreactor to nurture their creations for longer than any previous embryo models. The simulated embryos...
Stereotypes can be self-reinforcing, stubborn even without any supporting evidence
A new study from researchers at the University of Wisconsin-Madison shows why letting stereotypes inform our judgments of unfamiliar people can be such a hard habit to break.
Research confirms new baiting regime is effective for mouse management in agriculture
New research led by Australia's national science agency, CSIRO, has found that mouse populations can be reduced significantly by doubling the amount of zinc phosphide (ZnP) in grain baits used for broadscale agriculture.
Scientists reveal method of converting methane gas into liquid methanol
A group of researchers has succeeded in converting methane into methanol using light and dispersed transition metals such as copper in a process known as photo-oxidation. According to an article reporting the study published in Chemical Communications, the reaction was the best obtained to date for conversion of methane gas into liquid fuel under ambient conditions of temperature and pressure (25...
Researchers launch global dashboard to track invasive mosquitoes carrying deadly diseases
To combat the ongoing threat of mosquito-borne diseases worldwide, University of South Florida researchers have launched a mosquito-tracking dashboard driven by citizen science—a scalable solution proven effective in a recent USF study.
Weddell seal moms sacrifice diving capacity to provide iron to pups; climate change could add vulnerability
Weddell seals are excellent divers, and provide so much iron to their pups during lactation that the mothers dramatically limit their own diving and underwater foraging capabilities.
Major research associations submit Supreme Court amicus brief in support of race-conscious admissions practices
The American Educational Research Association (AERA) and six other leading research associations have submitted an amicus brief to the U.S. Supreme Court in support of narrowly tailored race-conscious admissions practices at Harvard University and the University of North Carolina. Joining AERA on the brief were the American Anthropological Association, the American Association for the Advancement...
A new study has used a marine monitor radar system to monitor California marine protected areas
A new study has found that boaters often cluster along the edges of marine protected areas (MPAs) off the coast of California. These new findings suggest that fishers are aware of the MPA boundaries and cluster just outside them to potentially benefit from better fishing opportunities by "fishing the line."
Dynamic travel restrictions can prevent rapid dispersion of new COVID-19 variants

- 22/8/2 21:33
Researchers recently announced that they have figured out how to engineer a biofilm that harvests the energy in evaporation and converts it to electricity. This biofilm has the potential to revolutionize the world of wearable electronics, powering everything from personal medical sensors to personal electronics.
Global forest area per capita has decreased by over 60 percent, study finds
- ScienceDaily
- 22/8/2 21:32
Over the past 60 years, the global forest area has declined by 81.7 million hectares, a loss that contributed to the more than 60 percent decline in global forest area per capita. This loss threatens the future of biodiversity and impacts the lives of 1.6 billion people worldwide, according to a new study.

The Guardian view on long Covid: an unknown enemy | Editorial
At least 2 million people in the UK are struggling with symptoms months or years after falling ill. They need support as well as treatmentHow do you tackle a problem when you don’t know what it is? Covid-19 was an unknown enemy, but was quickly identified. Long Covid, its equally unwelcome offspring, is a lesser threat, but is proving harder to pin down. Doctors are clear that it is widespread...
