A company made a fossil-free fuel out of ‘electrified CO2.’
It is almost equally fascinating to see old things pop up out of dust and new flashy things invented. Kory Anderson and his team in South Dakota did precisely the same thing. They breathed life back into a monster. As a result, the largest steam engine to have ever made, the 150HP Case, came to life nearly after a slumber of a century.
The JI Case Company based in Racine, Wisconsin, back in the day boasted the creation of this mammoth engine to their credit. It was used like a warhorse or a work mule to pull gigantic freights and heavy loads over long distances.
This magnanimous engines were produced for a little over two years, after which their production was shelved because of the lack of metallurgical advancements back in the day. Only 9 of these engines were produced, and their parts were later sold off for scrap. The only remnant of these engines was a boiler.
Some studies find students don’t learn as well by reading on screens as from paper. But that’s not always true. Here’s how to make the most of reading in either format.
Collaboration, transparency & urgency for rare disease research — mike graglia, managing director & co-founder, syngap research fund — SRF.
Mike Graglia is the Managing Director & Co-Founder of the SynGAP Research Fund (SRF — https://www.syngapresearchfund.org/), an organization that he set up in 2018 with his wife Ashley, after their son was diagnosed with a rare neurological disease caused by an insufficiency in SynGAP protein, which causes the life-changing diagnoses of Epilepsy, Autism, sleep disorder and intellectual disability.
The mission of SRF is to improve the quality of life of SynGAP1 patients through the research and development of treatments, therapies and support systems.
Scientists at the University of Chicago say that they’ve successfully created a “strange” new state of matter in the laboratory called “superionic ice” — and that the stuff might already exist inside planets in our solar system.
“It was a surprise — everyone thought this phase wouldn’t appear until you are at much higher pressures than where we first find it,” co-author and University of Chicago researcher Vitali Prakapenka said in a press blurb. “But we were able to very accurately map the properties of this new ice, which constitutes a new phase of matter, thanks to several powerful tools.”
Prakapenka’s team used a particle acclerator to fire electons between two pieces of diamond, creating unfathomable pressures of 20 gigapascals in a sample of water and causing it to form an entirely new structure that reverted when they relieved the pressure.
Title: A data analysis of the first hermetic seal of SAM–a hi-fidelity, hybrid physicochemical and bioregenerative human habitat analog at the Biosphere 2
Track Code: AM-8
Abstract:
SAM is a Space Analog for the Moon and Mars. This hi-fidelity, hermetically sealed habitat analog and research center is composed of a living quarters for four crew, workshop, dual airlocks, and greenhouse with temperature, humidity, and carbon dioxide level controls. SAM incorporates a half acre indoor/outdoor Mars yard with scaled crater, synthetic lava tube, and gravity offset rig for use in sealed pressure suits. SAM leverages the world class expertise and facilities at the University of Arizona’s Biosphere 2 and the Controlled Environment Agriculture Center (CEAC). As with other analogs, SAM welcomes research teams from around the world in an effort to inform near-future, long-duration human habitation of the Moon and Mars. With the close of June 2,021 a six months refurbishing of the 1987 prototype for the Biosphere 2 Test Module was completed. A crew of five were sealed inside for four hours. This was the first hermetic seal of this iconic vessel in three decades. The paper summarizes the data and findings pertaining to this closure, with review of the internal atmospheric pressure, CO2, O2, humidity and temperature data, including the effect of activation of a CO2 scrubber built by Paragon SDC for NASA.
From the 24th Annual International Mars Society Convention, held as a Virtual Convention worldwide on the Internet from October 14–17, 2021. The four-day International Mars Society Convention, held every year since 1,998 brings together leading scientists, engineers, aerospace industry representatives, government policymakers and journalists to talk about the latest scientific discoveries, technological advances and political-economic developments that could help pave the way for a human mission to the planet Mars.
“Hubble is the only telescope that has the kind of temporal coverage and spatial resolution that can capture Jupiter’s winds in this much detail”
Over the past 100 years, however, the cyclone has been dwindling, but recent observations with Hubble show that the wind speeds may be picking up again. Is this just temporary, or will the storm return to its former glory?
Using the Hubble Space Telescope, a team of astronomers has been monitoring the Great Red Spot for over a decade. They discovered that the wind speed of the outermost edge of the storm, known as the high-speed ring, has picked up speed by eight percent between 2009 and 2020.
Here we report a rapid Scalable and Portable Testing (SPOT) system consisting of a rapid, highly sensitive, and accurate assay and a battery-powered portable device for COVID-19 diagnosis. This device consists of 3D printed casing and internal structure with precise temperature control and fluorescence detection, whereas this assay combines RT-LAMP with an Argonaute protein from hyperthermophilic archaeon Pyrococcus furiosus (PfAgo) capable of precise recognition and cleavage of a target DNA at 95 °C as directed by small 5′-phosphorylated single strand DNA (ssDNA) as guide DNA (gDNA)10,11. Due to the multi-turnover activity of PfAgo, its secondary cleavage mechanism can be harnessed for specific, sensitive, and multiplex nucleic acid detection12,13. For COVID-19 samples, although nasopharyngeal swab and nasal swab samples were recommended for detection of SARS-CoV-2, saliva samples are a more attractive alternative due to the ease, safety, and non-invasive nature of its collection14,15, and its relatively high viral load during the first week of infection16. These benefits enable a saliva sample to be an ideal specimen for reliable and rapid self-detection without professional supervision17,18,19. While current CRISPR-based detection systems normally require 50 min for testing, PfAgo can dramatically speed up the detection process by requiring only 3–5 min for cleavage of amplified products, thereby shortening the total turnaround time for testing to less than 30 min. Moreover, successful PfAgo detection requires at least two sequence-specific cleavages, endowing the SPOT system with high specificity and the ability for multiplexing. Finally, to validate the SPOT system, the sensitivity and accuracy of the SPOT system were determined by using 104 clinical saliva samples.
- please note: The SPOT system also may be useful for detecting genetic markers of certain types of cancer in saliva.
There is a clear need for rapid, accurate and scalable Covid-19 diagnostics. Here the authors use PfAgo to detect viral sequences amplified by RT-LAMP in a handheld battery-powered device.
But the hydrogen-based material requires high pressure.
