Brain-computer interface (BCI) technologies are no longer hypothetical, yet there are fundamental aspects of the technology that remain unaddressed by both ethicists and policy-makers.
When the San Francisco Bay Area mandated shelter-in-place March 16, it created a natural experiment for UC Berkeley's Ron Cohen, who had established an inexpensive pollution sensor network in local neighborhoods. The sensors showed carbon dioxide emissions plummeting 25 percent in the subsequent six weeks, mostly because of a 48 percent drop in traffic. Networks like this -- soon to be emplaced in...
University of Copenhagen researchers have discovered how mosses became one of our planet's most widely distributed plants—global wind systems transport them along Earth's latitudes, to rooftops, sidewalks and lawns worldwide, and as far away as Antarctica. This new knowledge can provide us with a better understanding of how other small organisms are spread, including airborne bacteria and...
For adults, the goal of exercise is often to shed some pounds, but new research suggests the objective should be different for kids.
Diversifying agricultural systems beyond a narrow selection of crops leads to a range of ecosystem improvements while also maintaining or improving yields, according to a new study that analyzed thousands of previously conducted experiments. Diversification practices such as crop rotations and planting prairie strips can lead to 'win-win' results that protect the environment without sacrificing...
A new study investigates black-hole formation in neutron star mergers. Computer simulations show that the properties of dense nuclear matter play a crucial role, which directly links the astrophysical merger event to heavy-ion collision experiments at GSI and FAIR. These properties will be studied more precisely at the future FAIR facility.
Using high-speed video and schlieren imaging, a research engineer has created videos that show how air flows through masks with and without exhalation valves.
A study of how 98 million Americans move around each day suggests that most infections occur at 'superspreader' sites, and details how mobility patterns help drive higher infection rates among minority and low-income populations.
Groups of animals consider multiple factors before deciding whether to fight rivals, researchers say.
Bioengineers have used organoids - tiny lab-grown organs - to mimic the early development of the heart in the mouse embryo. The work is another step towards future bioartificial organs for research and transplants.
Seeking to develop effective interventions, researchers examined the psychological and environmental factors that lead to patterns of loneliness in different age groups.
Researchers say they have found more concrete evidence of the volcanic cause of the largest mass extinction of life. Their research looked at two discrete eruption events: one that was previously unknown to researchers, and the other that resulted in large swaths of terrestrial and marine life going extinct.
According to a new study, different groups of insectivores compete for the same type of food. Researchers made the discovery by comparing birds, bats and dragonflies that forage in the same area in Southwest Finland. These very distantly related predators consumed the same insect groups. The results shed new light on the decline in insect populations.
New research shows that the lowest risk for autism spectrum disorder is associated with mid-levels of an immune marker measured at birth -- whereas too much or not enough were linked to increased risk.
Scientists have detected what they say are the sediments of a huge ancient lake bed sealed more than a mile under the ice of northwest Greenland.
Scientists have shown that the size and makeup of groups of social birds can predict how efficiently they use and move through their habitat, according to new findings.
Researchers have discovered a new 'hidden' gene in SARS-CoV-2 -- the virus that causes COVID-19 -- that may have contributed to its unique biology and pandemic potential. In a virus that only has about 15 genes in total, knowing more about this and other overlapping genes -- or 'genes within genes' -- could have a significant impact on how we combat the virus.
Relapse in people with bipolar disorder can be predicted accurately by their tendency towards having pessimistic beliefs, according to a new study.
The universe is getting hotter, a new study has found. The study probed the thermal history of the universe over the last 10 billion years. It found that the mean temperature of gas across the universe has increased more than 10 times over that time period and reached about 2 million degrees Kelvin today -- approximately 4 million degrees Fahrenheit.
At last, there is hope of an end to this pandemic. Scientists appear to have performed an amazing feat, the rest of us must do our best tooMedicine is only partly a matter of science; it is, very much, the business of people. The inspiring news that a Covid vaccine appears within reach, with interim results showing the Pfizer/BioNTech candidate has 90% efficacy in protecting people from illness,...
My friend and former colleague Tony Trinci, who has died aged 84, was a world expert on fungi whose knowledge was often tapped by commercial enterprises, including Marlow Foods, when it was developing Quorn, and DuPont, which took his advice when adding fungal enzymes to animal feed.Tony was born in Swindon, Wiltshirem where his mother, Beatrice (nee Stefani), a restaurateur, had settled after...
Wearable exoskeletons are increasingly being used in physically demanding jobs to support good ergonomics and augment muscular strength. In ground-breaking studies, exoskeleton vests were worn by nurses to discover how the new technology would suit the special requirements of patient care.
In the Europe-wide FIThydro project, TalTech researchers worked with industry partners to study existing hydroelectric power plants. Together with researchers across Europe, they developed new assessment methods and technologies with the goal of making hydropower more fish-friendly and environmentally sustainable.
A species of bacteria can successfully pull out rare Earth elements from rocks, even in microgravity environments, a study on the International Space Station has found. The new findings, published in Nature Communications today, suggest a new way we could one day use microbes to mine for valuable metals and minerals off Earth. Why bacteria: Single-celled organisms have evolved over time...
During this pandemic, every activity in an indoor public place involves some level of risk, but some venues are far riskier than others—especially if they’re small and crowded. We already knew that restaurants can easily become covid hot spots, but a new paper published in Nature today quantifies just how dangerous they really are: four times riskier than the next riskiest location, which...
