Ultrahard chiton teeth discovery offers clues to next-generation advanced materials

The teeth of a mollusk can not only capture and chew food to nurture its body, but the marine choppers also hold insights into creating advanced, lower-cost and environmentally friendly materials.

David Kisailus, UC Irvine professor, and graduate student Taifeng Wang, both in and engineering, took a close look at the ultrahard teeth of the Northern Pacific Cryptochiton stelleri or gumboot chiton. Their findings are published in the Small Structures April 2022 issue.

“The findings in our work are critical, as it not only provides an understanding of the precision of in mineralization to form high-performance architected materials, but also provides insights into bioinspired synthetic pathways to a new generation of advanced materials in a broad range of applications from wear-resistant materials to ,” said Kisailus.

The Hydrogen Stream: Universal Hydrogen builds manufacturing facility in the United States

Abundant fuel cell raw materials and renewables potential could add up to a green hydrogen economy in the Philippines, according to Jose Mari Angelo Abeleda Jr and Richard Espiritu, two professors at the University of the Philippines Diliman. In a paper published in this month’s Energy Policy, they explained the country is a latecomer to the sector and should develop basic and applied knowledge for training and research. The country should also establish stronger links between industry and academia, the report’s authors suggested. “The establishment of the Philippine Energy Research and Policy Institute (Perpi) is a move towards the right direction as it will be instrumental in crafting policies and pushing for activities that will usher for more private-academ[ic] partnerships for the development of fuel cell technology in the Philippines,” the scholars wrote. “However, through enabling legislation, a separate and dedicated Hydrogen Research and Development Center (HRDC) will be pivotal in ensuring that sufficient government and private funding are provided.” The authors reported progress in the production of fuel cell membranes but few developments towards large scale production, transport, and storage facilities. “The consolidation of existing renewable energy sources for hydrogen production can also be explored in order to ensure reliable and sustainable hydrogen fuel supply,” they wrote. “This is because the country will gain more benefit if it focuses more on the application of fuel cell technology on rural electrification via renewa[ble] energy-based distributed power generation, rather than on transportation such as fuel cell vehicles.”

Paris-based energy engineering company Technip Energies and Indian energy business Greenko ZeroC Private have signed a memorandum of understanding (MOU) to explore green hydrogen project development opportunities in the refining, petrochemicals, fertilizer, chemical, and power plant sectors in India. “The MOU aims to facilitate active engagement between the teams of Technip Energies in India and Greenko to step up collaborative opportunities on a build-own-operate (BOO) model – in which Greenko will be the BOO operator and owner of the asset and Technip Energies will support with engineering services, integration and EP/EPC [engineering and procurement/engineering, procurement and constructrion] – for pilot and commercial scale green hydrogen and related projects in India in order to offer economically feasible technology solutions to clients,” the French company wrote today.

Elon Musk Shares Transphobic Meme Following Report of Grimes Dating Chelsea Manning

Sooner or later Musks childish, morally and politically inept use of social media will thwart his greater (and great) ambition. Whatever your personal beliefs, there is exactly ZERO doubt that every generation since and including millennials has become exponentially less willing to tolerate this kind of stuff. Musk is going to NEED to both the fresh and enthusiastic intelligence and majority scale support, and not JUST in SpaceX research labs and on site engineering teams either.

He’s going to need IMMENSE, PROLONGED, and RELIABLE political support even as the reins of power are being passed from one generation to the next. If he keeps using Twitter like he has nothing to lose and no one’s support He’s going to find that he really does no longer have anything to lose nor anyones support.

At that point, he’ll have difficulty getting from city to city, much less get to Mars to build CITIES or become a secure, far more survivable interplanetary civilization!

That would be a tragedy of possibly humanity extinguishing scale. Is THAT really worth the freedom to act like an entitled, petty child on social media?!

Musk and his dreams already have enemies enough. Why put HIMSELF at the top of that list? After all, this dream is NOT his alone, nor even remotly it’s originator. He’s just the only person to have the right mix of buisness acumen, technological literacy, enthusiasm, imagination, discipline, charisma, and luck to actually make it a reality. If he fails now, that dream WILL die. Whether its because of global warming, war, disease, atrophied critical thinking skills, educational decline, all of the above or some black swan event, the funds, time, will, and the global interconnectedness between scientific institutions and freedom to innovate and leverage those many convergent capabilities to achieve what MUST be achieved will be reduced or gone entirely. ☝️🤨👈

New window system allows for long-term studies of brain activity

Bilal Haider is studying how multiple areas of the brain work together for visual perception. This could help researchers understand if neural activity “traffic jams” underlie all kinds of visual impairments: from running a red light when visual attention is elsewhere, to shedding light on the autism-affected brain.

To do this kind of work, researchers need a reliable “map” of all the visual areas with specific coordinates for each unique brain. Drawing the map requires monitoring and recording data from an active, working brain, which usually means creating a window in the skull to watch blood flow activity.

Haider’s team has developed a better approach—a new kind of window that’s more stable and allows for longer-term studies. The assistant professor in the Wallace H. Coulter Department of Biomedical Engineering at Georgia Tech and Emory University explains how in a paper published in February in Scientific Reports.

New discoveries of deep brain stimulation put it on par with therapeutics

Despite having remarkable utility in treating movement disorders such as Parkinson’s disease, deep brain stimulation (DBS) has confounded researchers, with a general lack of understanding of why it works at some frequencies and does not at others. Now a University of Houston biomedical engineer is presenting evidence in Nature Communications Biology that electrical stimulation of the brain at higher frequencies (100Hz) induces resonating waveforms which can successfully recalibrate dysfunctional circuits causing movement symptoms.

“We investigated the modulations in local field potentials induced by electrical stimulation of the subthalamic nucleus (STN) at therapeutic and non-therapeutic frequencies in Parkinson’s disease patients undergoing DBS surgery. We find that therapeutic high-frequency stimulation (130−180 Hz) induces high-frequency oscillations (~300 Hz, HFO) similar to those observed with pharmacological treatment,” reports Nuri Ince, associate professor of biomedical engineering.

For the past couple of decades, (DBS) has been the most important therapeutic advancement in the treatment of Parkinson’s disease, a progressive nervous system disorder that affects movement in 10 million people worldwide. In DBS, electrodes are surgically implanted in the deep brain and electrical pulses are delivered at certain rates to control tremors and other disabling motor signs associated with the .

Tinybelt Enables Infinite 3D Printable at an Affordable Price

Traditional wisdom says that 3D printers are unsuitable for manufacturing. There are several reasons for that, including cost, part quality, and time, but labor is one of the most significant challenges. With conventional 3D printers, an operator must remove parts between jobs. That has a cost and slows down large production runs. Belt 3D printers solve this problem and also allow for infinite printing in one axis. Tinybelt, a new 3D printer on Kickstarter right now, makes this technology affordable.

The Tinybelt Kickstarter campaign is currently a third of the way to its $80,000 funding goal and needs your help to reach that goal. But you won’t want to contribute out of a sense of charity — you’ll want to back this campaign because Tinybelt has a lot to offer at an extremely competitive price. Tinybelt’s closest competition, the Creality CR-30 “3DPrintMill,” costs about $1,050. Tinybelt is available on Kickstarter right now for $499. Even at that low price, Tinybelt has a larger build volume than the competition.

As with other belt 3D printers 0, Tinybelt has one axis that is infinite. That means you can print parts as long as you want or print an unlimited number of parts—or both. The other two axes are 300mm and 200mm, which is almost twice the area of the Creality CR-30. A special nozzle made by Slice Engineering for the Mosquito hot end allows for printing at a shallower angle. Other specs are comparable, including the use of a dual-gear Bowden extruder.
