Innate lymphoid cells (ILCs) are crucial for protecting against bacterial infection in people with compromised immune systems, report investigators. Their work shows that a network of immune cells helps the appendix to play a pivotal role in maintaining health of the digestive system, supporting the theory that the appendix isn't redundant.
A researcher has successfully generated 3-D simulations of deep jet streams and storms on Jupiter and Saturn, helping to satiate our eternal quest for knowledge of planetary dynamics. The results facilitate a deeper understanding of planetary weather and provide clues to the dynamics of Earth's weather patterns evidenced in jet streams and ocean currents.
Extremely bright supernovas, called hypernovae, have been linked to gamma-ray bursts, but theorists have struggled to explain how a collapsing massive star could produce a magnetic field a million billion times greater than that of the sun, which is necessary to blow off the outer portions of the star and accelerate charged particles to speeds needed to produce gamma rays. A new supercomputer simulation shows how this happens.
Patients at safety-net hospital clinics where there was high computer use by clinicians were less likely to rate their care as excellent, according to an article.
A camera so advanced that it can photograph and film methane in the air around us is now presented by a team of researchers. It can be an important part of the efforts to measure and monitor greenhouse gases.
Policymakers, industry and government officials will have to invest US $2.5 trillion for electricity generation over the next 20 years. A new report presents the environmental costs and benefits linked to different renewable energy sources, and makes one thing abundantly clear: anything is better than coal.
A new report warns of the potential for major negative impacts on fish and fish habitat caused by large hydroelectric dams, like that currently under evaluation through the Next Generation Hydro initiative. The report, which focuses on north-western Canada, notes that substantial destruction of fish habitats caused by such a dam, along with additional threats and effects will be either very expensive or impossible to mitigate.
A novel class of antimicrobials that inhibits the function of a key disease-causing component of bacteria could be effective in fighting methicillin-resistant Staphylococcus aureus (MRSA), one of the major drug-resistant bacterial pathogens.
Researchers have observed an increase in body temperature of between two and four degrees in zebrafish, when these are subjected to stressful situations. This phenomenon is known as 'emotional fever,' as it is related to what animals feel in the face of an external stimulus.
Do you often take chances and yet still land on your feet? Then you probably have a well-developed brain.
Researchers have identified a potentially significant new application for a well-known human enzyme, which may have implications for treating respiratory diseases such as asthma.
Researchers discover method to prevent graft-versus-host disease, a dangerous and common complication of bone marrow transplants.
Bonobos documented for first time using ancient pre-agricultural tools, breaking bones, and using spears as attack weapons
Biologists have documented groups of bonobos performing complex actions to extract food -- a characteristic that has hitherto been regarded as an exclusive evolutionary advantage of archaic pre-humans.
By studying rocks at different elevations beside the East Antarctic Ice Sheet, scientists have concluded that a period of rapid glacier thinning occurred in the recent geological past, and persisted for several centuries.
CRISPR gene-editing is allowing rapid scientific advances in many fields, including human health and now it has been shown that crop research can also benefit from this latest exciting technology.
Using an old 19th century apartment block in Oslo as a case study, researchers are looking for conservation measures for heritage buildings. How can we make them watertight, insulated and protected against future climate change?
The lunar space environment is much more active than previously assumed. The solar wind is reflected from the surface and crustal magnetic fields of the moon which has effects on for instance lunar water levels.
New research has revealed how gaps between genes interact to influence the risk of acquiring diseases such as arthritis and type 1 diabetes.
Wearable equipment supports human motion where and when needed: Easier, faster, stronger, and more enjoyable
A new model of pneumatic muscle and an active type of assistive equipment incorporating this pneumatic muscle has been developed. This wearable equipment, called the Unplugged Powered Suit (UPS), supports human movement without requiring any electronic devices and tanks because it employs a newly developed pneumatic muscle named Pneumatic Gel Muscle (PGM) as an actuator. The UPS improves the quality of life of not only elderly individuals but also healthy people who enjoy sports activities.
While Canadian Prime Minister Justin Trudeau is in Paris hammering out the details of the global fight against climate change, a new study shows that Canadian attitudes are somewhat ambivalent. The report examines public perceptions of this complex policy problem.
