MINNEAPOLIS/SAINT PAUL (07/15/20) -- A new study from University of Minnesota researchers provides an unprecedented look at the causes of poor air quality in the United States and its effects on human health.
The research, to be published Wednesday in the journal Environmental Science and Technology Letters, finds that air pollution from sources in the United States leads to 100,000 deaths in the U.S. each year. About half of these deaths are from burning fossil fuels, but researchers also identified less obvious sources of lethal pollution.
On April 20, 2010, an explosion on the Deepwater Horizon oil rig triggered what would become the largest marine oil spill in history. Before the well was finally capped 87 days later on July 15, an estimated 4 million barrels of oil had gushed into the Gulf of Mexico, harming ecosystems, contaminating shorelines, and strangling the fishing and tourism industries.
Climate scientists Laura Jackson and Richard Wood from The Met Office, UK have identified metrics that may give us early warnings of abrupt changes to the European Climate. The work is part of the EU Horizon 2020 TiPES project which is coordinated by the Niels Bohr Institute at the University of Copenhagen, Denmark.
An important goal in climate science is to establish early warning systems - a climate alarm device, one might say - for abrupt changes to the system of sea currents in the Northern Atlantic Ocean.
The global coronavirus pandemic has hit the tourism industry hard worldwide. Not only that, but it has exposed a lack of resilience to any type of downturn, according to new research from Lund University in Sweden. While the virus may or may not be temporary, the climate crisis is here to stay - and tourism will have to adapt, says Stefan Gössling, professor of sustainable tourism.
TAMPA, Fla. -- Chimeric antigen receptor T-cell therapy (CAR T) has proved to be a valuable treatment option for patients with lymphoma who have failed other therapies. In clinical trials, the cellular immunotherapy was shown to provide durable remissions for nearly 40% of large B cell lymphoma patients. Despite its success, CAR T may not be the best option for all patients due to their cancer prognosis and the risk for developing severe toxicities or treatment-related death.
In American history, we learn that the arrival of Spanish explorers led by Hernando de Soto in the 1500s was a watershed moment resulting in the collapse of Indigenous tribes and traditions across the southeastern United States.
While these expeditions unquestionably resulted in the deaths of countless Indigenous people and the relocation of remaining tribes, new research from Washington University in St. Louis provides evidence that Indigenous people in Oconee Valley -- present-day central Georgia -- continued to live and actively resist European influence for nearly 150 years.
It might seem as though humans have little in common with the lowly yeast cell. Humans have hair, skin, muscles, and bones, among other attributes. Yeast have, well, none of those things.
Patients with gastrointestinal disorders - such as irritable bowel syndrome (IBS) and constipation - have greater symptom relief and improved wellbeing when treated at multidisciplinary clinics, new research shows.
Researchers from the University of Melbourne and St Vincent's Hospital have conducted a trial involving 144 patients to compare the effectiveness of a multidisciplinary clinic - involving gastroenterologists, dieticians, psychiatrists and physiotherapists - with usual gastroenterology specialist-only care.
The giant impacts that dominate late stages of planet formation have a wide range of consequences for young planets and their atmospheres, according to new research.
Research led by Durham University and involving the University of Glasgow, both UK, has developed a way of revealing the scale of atmosphere loss during planetary collisions based on 3D supercomputer simulations.
The simulations show how Earth-like planets with thin atmospheres might have evolved in an early solar system depending on how they are impacted by other objects.
Plant geneticists seeking to understand the history of the plants we eat can decode the genomes of ancient crops from rare, well-preserved samples. However, this approach leaves significant gaps in the timelines of where and when many modern-day fruits, vegetables, and cereal crops evolved, and paints an incomplete picture of what they looked like.
Addressing potential threats from predators has not slowed the dramatic decline of mountain caribou in British Columbia and Alberta, according to a new study by scientists from the University of Alberta and two other western Canadian universities.
Biologists reassessed data from research published in the Proceedings of the National Academy of Sciences (PNAS) in 2019. The original research has been cited as showing that killing wolves and fencing pregnant caribou are solutions to saving the endangered animals.
The known timeline of the Aboriginal occupation of South Australia's Riverland region has been vastly extended by new research led by Flinders University in collaboration with the River Murray and Mallee Aboriginal Corporation (RMMAC).
Radiocarbon dating of shell middens - remnants of meals eaten long ago - capture a record of Aboriginal occupation that extends to around 29,000 years, confirming the location as one of the oldest sites along the 2500km river to become the oldest River Murray Indigenous site in South Australia.
Consumption of DHA supplements, an omega-3 fatty acid, by breastfeeding mothers is ineffective in preventing bronchopulmonary dysplasia in preterm infants born before the 29th week of pregnancy. This is the main conclusion of a Canada-wide study published today in the Journal of the American Medical Association (JAMA).
LA JOLLA--(July 14, 2020) People wrongfully accused of a crime often wait years--if ever--to be exonerated. Many of these wrongfully accused cases stem from unreliable eyewitness testimony. Now, Salk scientists have identified a new way of presenting a lineup to an eyewitness that could improve the likelihood that the correct suspect is identified and reduce the number of innocent people sentenced to jail. Their report is published in Nature Communications on July 14, 2020.
New research led by The University of Queensland has provided the first comprehensive analysis of pesticide mixtures in creeks and rivers discharging to the Great Barrier Reef.
UQ's School of Earth and Environmental Sciences researcher Associate Professor Michael Warne conducted the study with the Queensland Department of Environment and Science, and analysed 2600 water samples from 15 waterways that discharge into the Great Barrier Reef lagoon over a four-year period.
