Emergency room doctors often have only a few minutes to determine which patients are in need of a blood transfusion.
But currently doctors have no direct method to assess the health of one of the most critical component of the blood: platelets. These tiny blood cells play a huge role in helping blood clot after an injury.
Across North America, coyotes are moving into urban environments, and regardless of how they feel about it, urban residents are having to get used to some new animal neighbors. A big question for wildlife researchers is how coyotes habituate to humans, which can potentially lead to conflict.
A study led by a University of Washington Tacoma faculty member, recently published in Ecology and Evolution, suggests coyotes can habituate to humans quickly and that habituated parents pass this fearlessness on to their offspring.
All the cells of an organism contain a copy of DNA in their nucleus. In order to implement the instructions it contains, this DNA must be copied into an RNA molecule, which reaches the ribosomes, which in turn read this information and synthesise proteins. The codons, animo acid triplets that form proteins and are the markers the ribosomes need to know how to produce each protein, are key in this transition process. There exist a total of 61 codons that code for 20 amino acids, and three codons that act as stop signals in the translation process.
A new biomarker that could be used to provide earlier diagnosis for a life limiting lung condition has been identified by researchers at the University of Bradford.
Pulmonary arterial hypertension (PAH) affects around 6,500 people in the UK and is caused by a narrowing of the arteries supplying blood to the lungs. This leads to high blood pressure and, eventually, to heart failure.
Fukuoka, Japan -- Humanity needs to improve when it comes to reducing carbon emissions to prevent the worst effects of climate change. If the world is to meet the IPCC's minimum target of keeping global temperature increases below 1.5 °C, every possible avenue for CO2 remediation must be explored.
SEATTLE - At what age do you feel 65?
A 30-year gap separates countries with the highest and lowest ages at which people experience the health problems of a 65-year-old, according to a new scientific study.
Researchers found 76-year-olds in Japan and 46-year-olds in Papua New Guinea have the same level of age-related health problems as an "average" person aged 65.
Researchers examined the visual response of 113 individuals when observing prehistoric ceramics belonging to different styles and societies. The ceramics analysed cover 4.000 years (from 4.000 B.C. to the change of era) of Galician prehistory (north-west Iberia), and are representative of ceramic styles, such as bell-beaker pottery, found throughout Europe. The results indicate that the visual behaviour follows the same evolutionary trends as those that drive the evolution of the complex societies that built these archaeological materialities.
Marine scientists from WCS (Wildlife Conservation Society) and other groups examining the ecological status of coral reefs across the Indian and Pacific oceans have uncovered an unsettling fact: even the best coral reef marine parks contain less than half of the fish biomass found in the most remote reefs that lie far from human settlements.
The study titled "Global baselines and benchmarks for fish biomass: comparing remote reefs and fisheries closures" appears in the new edition of the journal Marine Ecology Progress Series.
Eighty-six percent of individuals who entered HIV care soon after diagnosis maintained viral suppression after 48 weeks during a clinical trial conducted at four National Institutes of Health (NIH)-funded Centers for AIDS Research (CFARs) across the United States. Participants in the clinical trial, called iENGAGE, achieved viral suppression in an average of just 63 days.
Simple, inexpensive urban design interventions can increase well-being and social connections among city residents, finds a new case study from the Urban Realities Lab at the University of Waterloo.
Researchers found that green spaces and colourful, community-driven urban design elements were associated with higher levels of happiness, greater trust of strangers, and greater environmental stewardship than locations without those amenities.
Scientists have shed light on how healthy cells develop by identifying the role of key molecules involved.
The components, known as R-loops, are formed during cell development and have been shown to play an important role in the process. The latest finding overturns previous thinking that R-loops, formed from the genetic material that makes up DNA, were harmful to cells.
Researchers found that R-loops work together with a group of cell proteins, known as Polycomb, to control genes that are important for development in humans and other mammals.
DALLAS - March 6, 2019 - UT Southwestern researchers used cryo-electron microscopy (cryo-EM) to determine the near-atomic structure of the smallest membrane protein solved to date. Their work could lead to better immunotherapies in cancer and improved treatments for autoimmune diseases like lupus.
Ithaca, NY--Using data on 77 North American migratory bird species from the eBird citizen-science program, scientists at the Cornell Lab of Ornithology say that, in as little as four decades, it may be very difficult to predict how climate change will affect migratory bird populations and the ecosystems they inhabit. Their conclusions are presented in a paper published in the journal Ecography.
When naturalist Charles Darwin stepped onto the Galapagos Islands in 1835, he encountered a bird that sparked a revolutionary theory on how new species originate. From island to island, finches had wildly varied beak designs that reflected their varied diets. The so-called Darwin's finches are an emblem of adaptive radiation, which describes when organisms from a single lineage evolve different adaptations in response to competitors or predators.
A large breakthrough has been made in the genetic understanding of mouth ulcers which could provide potential for a new drug to prevent or heal the painful lesions. Mouth ulcers affect up to 25 per cent of young adults and a higher proportion of children. Previous research has shown that mouth ulcers are partially heritable, but until now there has been little evidence linking specific genes or genomic regions to mouth ulcers.
