Immune cells make appendix 'silent hero' of digestive health

Mon, 30/11/2015 - 6:00pm
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.

Simulating the jet streams and anticyclones of Jupiter and Saturn

Mon, 30/11/2015 - 5:52pm
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.

Missing link found between turbulence in collapsing star and hypernova, gamma-ray burst

Mon, 30/11/2015 - 5:52pm
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.

Benefits and trade-offs of low-carbon energy

Mon, 30/11/2015 - 5:50pm
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.

Large-scale hydroelectric dam in Yukon would be a major environmental concern

Mon, 30/11/2015 - 4:37pm
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.

Could fish have consciousness? 'Emotional fever' experiment suggests they might

Mon, 30/11/2015 - 4:35pm
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.

Wearable equipment supports human motion where and when needed: Easier, faster, stronger, and more enjoyable

Mon, 30/11/2015 - 1:45pm
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.
