A new study revealed that more college students change majors within the STEM pipeline than leave the career path of science, technology, engineering and mathematics altogether.
Scientists have identified 'words' immune cells use to call up immune defense genes -- an important step toward understanding their language. The scientists also discovered that in an autoimmune disease, Sjögren's syndrome, two of these words are used incorrectly, activating the wrong genes and triggering the disease.
While standing dead trees in ghost forests did not release as much greenhouse gas emissions as the soils, they did increase GHG emissions of the overall ecosystem by about 25 percent, a new study has found.
An immune system that mistakes our good gut bacteria for an enemy can cause a dangerous type of inflammation in the intestines called colitis. An immune system that looks the other way while gut microbes spill past their assigned borders is equally dangerous. Understanding how the immune system learns to make a brokered peace with its microbial residents, called the microbiota, is therefore an...
Research reveals insights into how the body maintains balance with 'good' gut bacteria that allows these microbes to flourish in the intestine but keeps them out of tissues and organs where they're not supposed to be.
Researchers have found a way to study uterine fluid in the lab, thereby avoiding invasive procedures during pregnancy, while at the same time developing a potential model for using precision medicine to improve pregnancy outcomes.
In 2020, stores sold out of garden seed, coops and rabbit cages. Meat shortages led many to wonder what to eat for protein when supply chains are disrupted and some people turned to gathering eggs, raising animals and growing their own food. A team assessed backyard protein sources: They looked at how a typical household with a typical backyard can raise chickens, rabbits or soybeans to meet its...
Researchers found that senescent immune cells are the most dangerous type of senescent cell.
A study of the 2020 influenza figures from Canada, the United States, Australia and Brazil shows that there is a clear relationship between COVID-mitigation measures such as hand-washing, masking and social distancing and the spread of the annual flu, researchers report. They write that these preventive measures all but eliminated the flu in countries where it can kill tens of thousands of people...
Guatemala's Pacaya volcano has been erupting since February, keeping local communities and authorities on high alert.
Boggy marshes and wetlands across the country are the secret stars of carbon capture, but most people don’t understand their worth, said Christina Davy, a research scientist for the Ontario Ministry of Natural Resources and...
Citrus greening disease was first discovered in Florida in 2005. Since then, production of oranges in the United States for processing has declined by 72 percent between the 2007-2008 growing season and the 2017-2018 growing season, primarily in Florida. The disease was discovered in California in 2012, and now the state is beginning to see a rapid increase of citrus greening disease.
The sun has burped out a stream of particles that, if conditions are right, might produce northern lights across Canada...
A new study by the University of Georgia revealed that more college students change majors within the STEM pipeline than leave the career path of science, technology, engineering and mathematics altogether.
A Rutgers study finds that symbiotic bacteria that colonize root cells may be managed to produce hardier crops that need less fertilizer.
Brown bears that are more inclined to grate and rub against trees have more offspring and more mates, according to a University of Alberta study. The results suggest there might be a fitness component to the poorly understood behavior.
When the Big One hits, the first thing Washington residents notice may not be the ground shaking but their phone issuing a warning. The U.S. Geological Survey, the University of Washington-based Pacific Northwest Seismic Network, and the Washington Emergency Management District on Tuesday, May 4, will activate the system that sends earthquake early warnings throughout Washington state. This...
Chemically synthesized short DNA sequences are extremely important ingredients with countless uses in research laboratories, hospitals, and in industry, like in the method for identifying COVID-19. Phosphoramidites are necessary building blocks in the production of DNA sequences, but they are unstable, and break quickly. Ph.D. Alexander Sandahl (Professor Kurt Gothelf's group, Aarhus University)...
The Earth's first forest fires appear to have occurred earlier than previously thought, pointing out a link between widespread wildfires and ancient tree evolution, according to researchers at The University of Alabama.
The financing from a Toronto investment bank will allow construction to begin at the site this fall, says Maritime Launch...
Scientists have unveiled a new Ebola virus vaccine design, which they say has several advantages over standard vaccine approaches for Ebola and related viruses that continue to threaten global health. In the new design copies of the Ebola virus outer spike protein, known as the glycoprotein, are tethered to the surface of a spherical carrier particle.
A Rutgers study finds that symbiotic bacteria that colonize root cells may be managed to produce hardier crops that need less fertilizer.
Scientists have for the first time revealed the structure surrounding important receptors in the brain's hippocampus, the seat of memory and learning. The new study focuses on the organization and function of glutamate receptors, a type of neurotransmitter receptor involved in sensing signals between nerve cells in the hippocampus region of the brain. The study reveals the molecular structure of...
Immense research efforts are invested in figuring out how the virus manages to mount an effective invasion while throwing the immune system off course. A new study reveals a multipronged strategy that the virus employs to ensure its quick and efficient replication, while avoiding detection by the immune system.
Brown bears that are more inclined to grate and rub against trees have more offspring and more mates, according to a new study. The results suggest there might be a fitness component to the poorly understood behavior.
Researchers show that prior studies have underestimated the cooling in the last glacial period, which has low-balled estimates of the Earth's climate sensitivity to greenhouse gases. The rather high climate sensitivity is not good news regarding future global warming, which may be stronger than expected using previous best estimates.
