Why trackless trams are ready to replace light rail
Posted by Bill Kemp in categories: government, robotics/AI, transportation
I began my life as an activist academic in 1979 when the Western Australian government closed the Fremantle railway, saying buses would be better. Patronage immediately fell by 30% and I ran a four-year campaign to save the railway. We won. I have been writing books and running campaigns ever since on why trains and trams are better than buses. But I have changed my mind. The technology has changed, and I think it will end the need for new light rail.
“Trackless trams” are based on technology created in Europe and China by taking innovations from high-speed rail and putting them in a bus.

NLRP12 Protein Protects Mice Against Obesity
Posted by Steve Hill in categories: biotech/medical, habitats
A study from the UNC School of Medicine showed that the protein NLRP12, known for its anti-inflammatory effects, also protects mice on a high-fat diet against obesity and insulin resistance; it might have a similar effect in humans [1].
Study abstract
In addition to high-fat diet (HFD) and inactivity, inflammation and microbiota composition contribute to obesity. Inhibitory immune receptors, such as NLRP12, dampen inflammation and are important for resolving inflammation, but their role in obesity is unknown. We show that obesity in humans correlates with reduced expression of adipose tissue NLRP12. Similarly, Nlrp12/ mice show increased weight gain, adipose deposition, blood glucose, NF-kB/ MAPK activation, and M1-macrophage polarization. Additionally, NLRP12 is required to mitigate HFD-induced inflammasome activation. Co-housing with wild-type animals, antibiotic treatment, or germ-free condition was sufficient to restrain inflammation, obesity, and insulin tolerance in Nlrp12/ mice, implicating the microbiota. HFD-fed Nlrp12/ mice display dysbiosis marked by increased obesity-associated Erysipelotrichaceae, but reduced Lachnospiraceae family and the associated enzymes required for short-chain fatty acid (SCFA) synthesis.

This Robotic Skin Makes Inanimate Objects Move
Posted by Genevieve Klien in categories: robotics/AI, wearables
When designing a robot, key components are the robot’s sensors, which allow it to perceive its environment, and its actuators, the electrical or pneumatic motors that allow the robot to move and interact with its environment.
Consider your hand, which has temperature and pressure sensors, but also muscles as actuators. The omni-skins, as the Science Robotics paper dubs them, combine sensors and actuators, embedding them into an elastic sheet. The robotic skins are moved by pneumatic actuators or memory alloy that can bounce back into shape. If this is then wrapped around a soft, deformable object, moving the skin with the actuators can allow the object to crawl along a surface.
