The link between on-road traffic and air pollution is well-known, as are the negative health impacts of pollution exposure. However, the many factors that may influence commuters' exposure to pollutants—such as frequency, time, and duration of commute—and the overall impact of commuting remains a matter of on-going scientific discovery.
By uprooting carbon trapped in soil, wild pigs are releasing around 4.9 million metric tons of carbon dioxide annually across the globe, the equivalent of 1.1 million cars.
What's a hungry marine microbe to do when the pickings are slim? It must capture nutrients—nitrogen, phosphorus, or iron—to survive, yet in vast expanses of the ocean, nutrients are extremely scarce. And the stakes are high: Marine microbial communities drive many of the elemental cycles that sustain all life on Earth.
Politicians may have good reason to turn to angry rhetoric, according to research led by political scientists from Colorado—the strategy seems to work, at least in the short term.
The nation's largest wildfire torched more dry forest in Oregon and forced the evacuation of a wildlife research station Monday as firefighters had to retreat from the flames for the ninth consecutive day due to erratic and dangerous fire behavior.
Over the weekend, a consortium of international news outlets published their findings from an investigation into the use of Pegasus, the marquee spyware of secretive billion-dollar Israeli surveillance company NSO group. The reports from the Guardian, the Washington Post, and 15 other media organizations, are based on a leak of tens of thousands of phone numbers that appear to have been...
New research examines commuter characteristics to better understand how factors such as departure time, frequency, and commute length are associated with exposure to air pollution. Using personal air pollution monitors, the research clustered commuters to determine whether these clusters were associated with traffic pollution exposures. The study reveals that commuters that travel during rush hour...
Researchers have discovered another functional autoantibody in COVID-19 patients that contributes to the disease's development and the 'firestorm' of blood clots and inflammation it induces. The autoantibody makes it much harder for the body to degrade neutrophil extracellular traps, the toxic webs of DNA and proteins produced by overactive immune cells at heightened levels in COVID patients.
A new approach to analyse satellite measurements of Earth's cloud cover reveals that clouds are very likely to enhance global heating.
By uprooting carbon trapped in soil, wild pigs are releasing around 4.9 million metric tonnes of carbon dioxide annually across the globe, the equivalent of 1.1 million cars, according to new research.
New research has found marine seismic surveys used in oil and gas exploration are not impacting the abundance or behaviour of commercially valuable fishes in the tropical shelf environment in north-western Australia.
Scientists are developing a low-cost, practical biopolymer dressing that helps heal chronic wounds.
Parenting deficiencies have long been blamed for the vocabulary gap between low-income children and their more affluent peers. But new research implicates the economic context in which parenting takes place -- in other words, the wealth gap.
Researchers discover a signaling protein that controls the assembly of human cellular 'power plants'.

Throughout history, people of different cultures and stages of evolution have found ways to adapt, with varying success, to the gradual warming of the environment they live in. But can the past inform the future, now that climate change is happening faster than ever before?
A new approach to analyze satellite measurements of Earth's cloud cover reveals that clouds are very likely to enhance global heating.
A major drought and forest fires in the Amazon rainforest killed billions of trees and plants and turned one of the world's largest carbon sinks into one of its biggest polluters.
In 1930, Clyde Tombaugh, a 25-year-old amateur astronomer, spied a small, dim object in the night sky. He’d been working at the Lowell Observatory in Flagstaff, Arizona, for about a year when he used a blink comparator—a special kind of microscope that can examine and compare images—to glimpse what was for a time considered to be the ninth planet in our...
A new robotic neck brace may help doctors analyze the impact of cancer treatments on the neck mobility of patients and may help guide their recovery.
Did you know multiple sclerosis (MS) means multiple scars? New research shows that the brain and spinal cord scars in people with MS may offer clues to why they developprogressive disability but those with related diseases where the immune system attacks the central nervous system do not. Researchers assessed if inflammation leads to permanent scarring in these three diseases.
A new study shows that DNA duplication has been vitally important throughout the evolutionary history of gymnosperms, a diverse group of seed plants that includes pines, cypresses, sequoias, ginkgos and cycads.
Researchers have found a low-cost way to solve one half of the water-splitting equation to produce hydrogen as clean energy -- using sunlight to efficiently split off oxygen molecules from water. The finding represents a step forward toward greater adoption of hydrogen as a key part of our energy infrastructure.
An RNA modification may offer protection against non-alcoholic fatty liver, a condition that results from a build-up of fat in the liver and can lead to advanced liver disease, according to a new study. The modification may also explain why females tend to have higher fat content in the liver.
What's a hungry marine microbe to do when the pickings are slim? It must capture nutrients - nitrogen, phosphorus, or iron - to survive, yet in vast expanses of the ocean, nutrients are extremely scarce.
Statistician says PM’s initial excuse for not self-isolating is part of pattern of pilot studies that lack transparencyCoronavirus – latest updatesSee all our coronavirus coverageA scientist has cast doubt on the validity of a workplace pilot scheme used by Boris Johnson and Rishi Sunak to initially avoid self-isolation, accusing the government of secrecy surrounding it and other research.On...
One of the topics investigated in recent physics studies is strong-field quantum electrodynamics (SF-QED). So far, this area has rarely been explored before, mainly because the experimental observation of SF-QED processes would require extremely high light intensities (>1025W/cm2), over three orders of magnitude higher than those attained using the most intense PetaWatt (PW)-class lasers available...
A suite of International Space Station scientific experiments soon journey back to Earth aboard the 22nd SpaceX commercial resupply services mission for NASA. Scientists on the ground look forward to having their experiments back within hours, an advantage that could provide better results. Dragon undocks from the space station July 7.
For decades, researchers around the world have searched for ways to use solar power to generate the key reaction for producing hydrogen as a clean energy source—splitting water molecules to form hydrogen and oxygen. However, such efforts have mostly failed because doing it well was too costly, and trying to do it at a low cost led to poor performance.
Flavor is the name of the game for scientists who want to optimize food for consumption in ways that improve nutrition or combat obesity.
Analysis of children and young people's proximity to woodlands has shown links with better cognitive development and a lower risk of emotional and behavioral problems, in research led by UCL and Imperial College London scientists that could influence planning decisions in urban areas.
For dairy cows, the transition period—the time between a cow giving birth and beginning to produce milk—brings the greatest possibility of health problems. The current widespread belief is that the effects of excess nonesterified fatty acids (NEFA) in the bloodstream and the ensuing hyperketonemia during this period, coupled with low levels of available calcium, are largely responsible for...
The Giant Galapagos tortoises which live in contact with human farming and tourism activities, or in urbanized zones, have more bacterial resistance to antibiotics than those that live in more isolated ecosystems.
A serendipitous flythrough of the tail of a disintegrated comet has offered scientists a unique opportunity to study these remarkable structures, in new research presented today at the National Astronomy Meeting 2021.
