Radiant Aims To Replace Diesel Generators With Small Nuclear Reactors

Slashdot - Science - Lun, 18/10/2021 - 22:30
An anonymous reader quotes a report from New Atlas: California company Radiant has secured funding to develop a compact, portable, "low-cost" one-megawatt nuclear micro-reactor that fits in a shipping container, powers about 1,000 homes and uses a helium coolant instead of water. Founded by ex-SpaceX engineers, who decided the Mars colony power sources they were researching would make a bigger impact closer to home, Radiant has pulled in $1.2 million from angel investors to continue work on its reactors, which are specifically designed to be highly portable, quick to deploy and effective wherever they're deployed; remote communities and disaster areas are early targets. The military is another key market here; a few of these could power an entire military base in a remote area for four to eight years before expending its "advanced particle fuel," eliminating not just the emissions of the current diesel generators, but also the need to constantly bring in trucks full of fuel for this purpose. Those trucks will still have to run -- up until the point where the military ditches diesel in all its vehicles -- but they'll be much less frequent, reducing a significant risk for transport personnel. Radiant says its fuel "does not melt down, and withstands higher temperatures when compared to traditional nuclear fuels." Using helium as the coolant "greatly reduces corrosion, boiling and contamination risks," and the company says it's received provisional patents for ideas it's developed around refueling the reactors and efficiently transporting heat out of the reactor core.

MIT Researchers Create 'Robotic' Textiles To Make Breath-Regulating Garments

Slashdot - Science - Lun, 18/10/2021 - 21:02
A new kind of fiber developed by researchers at MIT and in Sweden can be made into clothing that senses how much it is being stretched or compressed, and then provides immediate tactile feedback in the form of pressure, lateral stretch, or vibration. Such fabrics, the team suggests, could be used in garments that help train singers or athletes to better control their breathing, or that help patients recovering from disease or surgery to recover their breathing patterns. From a report: The multilayered fibers contain a fluid channel in the center, which can be activated by a fluidic system. This system controls the fibers' geometry by pressurizing and releasing a fluid medium, such as compressed air or water, into the channel, allowing the fiber to act as an artificial muscle. The fibers also contain stretchable sensors that can detect and measure the degree of stretching of the fibers. The resulting composite fibers are thin and flexible enough to be sewn, woven, or knitted using standard commercial machines. The fibers [are] dubbed OmniFibers [...]. The new fiber architecture has a number of key features. Its extremely narrow size and use of inexpensive material make it relatively easy to structure the fibers into a variety of fabric forms. It's also compatible with human skin, since its outer layer is based on a material similar to common polyester. And, its fast response time and the strength and variety of the forces it can impart allow for a rapid feedback system for training or remote communications using haptics (based on the sense of touch). As an initial test application of the material, the team made a type of undergarment that singers can wear to monitor and play back the movement of respiratory muscles, to later provide kinesthetic feedback through the same garment to encourage optimal posture and breathing patterns for the desired vocal performance. Though this initial testing is in the context of vocal pedagogy, the same approach could be used to help athletes to learn how best to control their breathing in a given situation, based on monitoring accomplished athletes as they carry out various activities and stimulating the muscle groups that are in action. Eventually, the hope is that such garments could also be used to help patients regain healthy breathing patterns after major surgery or a respiratory disease such as Covid-19, or even as an alternative treatment for sleep apnea.

New active agent against parasites

Science Daily - Lun, 18/10/2021 - 16:22
Researchers have identified a chemical compound that may be suitable as an active agent against several different unicellular parasites. Among these are the pathogens that cause malaria and toxoplasmosis. The point of attack for this promising substance is the protein tubulin: It helps cells divide and therefore is essential for the multiplication of the parasites.

Putting honeybee hives on solar parks could boost the value of UK agriculture

Science Daily - Lun, 18/10/2021 - 16:22
The value of UK agriculture could be boosted by millions of pounds a year if thousands of honeybee hives were deployed on solar parks across the country, a new study reveals. However, scientists caution that the benefits of managing solar parks for wild pollinators over honeybees should be prioritized where appropriate and should be assessed on a site by site basis.

Researchers identify brain circuitry in rodents that may be responsible for negative emotional aspects of pain

Science Daily - Lun, 18/10/2021 - 16:22
A new study has uncovered neuronal circuitry in the brain of rodents that may play an important role in mediating pain-induced anhedonia -- a decrease in motivation to perform reward-driven behaviors. Researchers were able to change the activity of this circuit and restore levels of motivation in a pre-clinical model of pain tested in rodents.
