Despite a name straight from a Tarantino movie, natural killer (NK) cells are your allies when it comes to fighting infections and cancer. If T cells are like a team of specialist doctors in an emergency room, NK cells are the paramedics: They arrive first on the scene and perform damage control until reinforcements arrive.
Part of our innate immune system, which dispatches these first responders, NK cells are primed from birth to recognize and respond to danger. Learning what fuels NK cells is an active area of research in immunology, with important clinical implications.
New research from the Georgia Institute of Technology finds that elephants dilate their nostrils in order to create more space in their trunks, allowing them to store up to nine liters of water. They can also suck up three liters per second -- a speed 30 times faster than a human sneeze (150 meters per second/330 mph).
AMES, Iowa - An unexpected discovery by an Iowa State University researcher suggests that the first humans may have arrived in North America more than 30,000 years ago - nearly 20,000 years earlier than originally thought.
Key takeaways
The surgical simulator can realistically simulate multiple trauma scenarios at once, compared with traditional simulators that can only simulate one or a limited number of conditions.
Trauma team members who tested the simulator preferred it for its realism, physiologic responses, and feedback.
The benefits of this innovative simulator may be able to extend to other surgical procedures and settings.
Berkeley -- Global land-use changes -- including forest fragmentation, agricultural expansion and concentrated livestock production -- are creating "hot spots" favorable for bats that carry coronaviruses and where conditions are ripe for the diseases to jump from bats to humans, finds an analysis published this week by researchers at the University of California, Berkeley, the Politecnico di Milano (Polytechnic University of Milan) and Massey University of New Zealand.
CHICAGO -- Women who experience acute aortic dissection--a spontaneous and catastrophic tear in one of the body's main arteries--not only are older and have more advanced disease than men when they seek medical care, but they also are more likely to die, according to research published online today in The Annals of Thoracic Surgery.
Can you trust the map on your smartphone, or the satellite image on your computer screen?
So far, yes, but it may only be a matter of time until the growing problem of "deep fakes" converges with geographical information science (GIS). Researchers such as Associate Professor of Geography Chengbin Deng are doing what they can to get ahead of the problem.
It is time for the management and conservation of the Antarctic to begin focusing on responsibility, rather than rights, through an Indigenous Māori framework, a University of Otago academic argues.
In an article published in Nature Ecology & Evolution, Associate Professor Priscilla Wehi, of the Centre for Sustainability, says now is the time to be thinking of these potential changes.
By ensuring ethnic diversity in a largescale genetic study, an international team of researchers, including a University of Massachusetts Amherst genetic epidemiologist, has identified more regions of the genome linked to type 2 diabetes-related traits.
The quality of a sewn garment is dependent on the quality of its seams that are the basic structural element. The factors affecting seam quality in garments include sewing thread type and stitch density. Making the right choice of these helps in getting quality seams in garments. However, the choice of suitable sewing threads and stitch densities for particular fabrics can only be determined through testing.
How old is your brain compared to your chronological age? A new measure of brain health developed by researchers at Rush University Medical Center may offer a novel approach to identifying individuals at risk of memory and thinking problems, according to research results published in Alzheimer's & Dementia: The Journal of the Alzheimer's Association on June 1.

A new study published in Proceedings of National Academics of Sciences finds that individuals who falsely believe they are able to identify false news are more likely to fall victim to it. In the article published today, Ben Lyons, assistant professor of communication at the University of Utah, and his colleagues examine the concern about the public's susceptibility to false news due to their inability to recognize their own limitations in identifying such information.
