AUSTIN, Texas — As much as a third of the world’s population does not have access to clean drinking water, according to some estimates, and half of the population could live in water-stressed areas by 2025. Finding a solution to this problem could save and improve lives for millions of people, and it is a high priority among scientists and engineers around the globe.
Scientists and engineers at The University of Texas at Austin have created a hydrogel tablet that can rapidly purify contaminated water. One tablet can disinfect a liter of river water and make it suitable for drinking in an hour or less.
“Our multifunctional hydrogel can make a big difference in mitigating global water scarcity because it is easy to use, highly efficient and potentially scalable up to mass production,” said Guihua Yu, an associate professor in the Cockrell School of Engineering’s Walker Department of Mechanical Engineering and Texas Materials Institute.
Tesla’s impressive third-quarter delivery performance overshadowed the automotive industry’s ongoing struggle with the semiconductor chip shortage. Among all of the world’s automakers, Tesla has been basically the only car company to avert the crisis as it has not had any overwhelmingly public stoppages in vehicle production. Morgan Stanley’s new investor note, drafted by lead analyst Adam Jonas, examines Tesla’s ability to avoid detrimental production stoppages, which effectively helped the company capture its best quarter in company history.
Jonas titles Morgan Stanley’s most recent investor note, “How Did Tesla Find Chips?” In all honesty, this riddle was solved during the Q2 2021 Earnings Call, where Tesla stated in its Shareholder Deck that it used a combination of in-house microcontrollers to avoid any major catastrophes in the manufacturing of its vehicles. The company wrote:
“Our team has demonstrated an unparalleled ability to react quickly and mitigate disruptions to manufacturing caused by semiconductor shortages. Our electrical and firmware engineering teams remain hard at work designing, developing and validating 19 new variants of controllers in response to ongoing semiconductor shortages.”
Imagine an iPad or a Kindle for the blind, with inflatable Braille that changes shape under a user’s touch. A Cornell-led collaboration has made a crucial component for such a technology: A haptic array of densely packed actuators that cause silicone membrane “dots” to pop up when triggered by combustion.
The team’s paper, “Valveless Microliter Combustion for Densely Packed Arrays of Powerful Soft Actuators,” published Sept. 28 in Proceedings of the National Academy of Sciences. The lead author is doctoral student Ronald Heisser.
One of the major hurdles for designing a dynamic Braille display for electronics is figuring out how to apply the necessary amount of force for each dot. Previous attempts have usually involved motors, hydraulics or tethered pumps, all of which are cumbersome, complex and expensive, according to Rob Shepherd, associate professor of mechanical and aerospace engineering in the College of Engineering and the paper’s senior author.
And, depending on how further studies progress, it could be implemented via gene therapy.
Early-stage pancreatic cancer has a ‘reset button’
“These findings open up the possibility of designing a new gene therapy or drug because now we can convert cancerous cells back into their normal state,” said Professor Bumsoo Han of Purdue’s mechanical engineering, who is also the program leader for the university’s Center for Cancer Research, in a blog post shared on the university’s official website. Han has also received a courtesy appointment in biomedical engineering, according to the post. The new time machine (speaking figuratively) from Han’s lab is a lifelike reproduction of a specific structure of the pancreas, called the acinus, which secretes and produces digestive enzymes into the small intestine. When pancreatic cancer strikes, it typically comes from chronic inflammation, which is caused by a mutation that tricks the digestive enzymes to begin digesting the pancreas itself. This is bad.
An international team of researchers has used liquid gallium to create an antiviral and antimicrobial coating and tested it on a range of fabrics, including facemasks. The coating adhered more strongly to fabric than some conventional metal coatings, and eradicated 99% of several common pathogens within five minutes.
“Microbes can survive on the fabrics hospitals use for bedding, clothing and face masks for a long time,” says Michael Dickey, co-corresponding author of a paper on the work and Camille & Henry Dreyfus Professor of Chemical and Biomolecular Engineering at North Carolina State University. “Metallic surface coatings such as copper or silver are an effective way to eradicate these pathogens, but many metal particle coating technologies have issues such as non-uniformity, processing complexity, or poor adhesion.”
Dickey and colleagues from NC State, Sungkyunkwan University (SKKU) in Korea and RMIT University in Australia set out to develop a simple, cost-effective way to deposit metal coatings on fabric.
As part of a SpaceX Falcon 9 launch that will send a commercial Moon lander on its way to Earth’s nearest neighbor, rideshare organizer Spaceflight Inc and propellant depot startup OrbitFab have revealed plans for the first high Earth orbit propellant depot.
Known as “Tanker-002,” the co-developed spacecraft will technically be the first propellant depot – essentially a gas station in space – to reach a geostationary orbit ~36,000 km (~22,300 mi) above the Earth’s surface. Based around a variant of Spaceflight’s brand new Sherpa OTV space tug vehicles, OrbitFab hasn’t disclosed the planned capacity of its unique GEO depot but the public specifications of Sherpa suggest that the company will be able to deliver a few hundred kilograms (300−800 lb) of hydrazine accessible via several tiny docking ports.
However, Tanker-002 isn’t interesting solely for its unique position as a tanker in GEO. How Spaceflight and OrbitFab plan to get the small spacecraft into position will be a feat of engineering and trajectory design in its own right.

Reverse-engineering our thinking should be done in terms of networks, modules, algorithms and second-order emergence — meta-algorithms, or groups of modules. Neuronal circuits correlate to “immaterial” cognitive modules, and these cognitive algorithms, when activated, produce meta-algorithmic conscious awareness and phenomenal experience, all in all at least two layers of emergence on top of “physical” neurons.
Reality is fundamentally experiential. Nothing is real for us until perceived. The Conscious Instant Hypothesis denotes that we experience waking reality as a series of perceptual frames. Phenomenal mind springs into existence at increments of conscious instants. A series of such conscious instants constitutes a data stream of consciousness. In a sense, consciousness is really mind-based computing of your experiential branch in this quantum multiverse.
John Archibald Wheeler (1911−2008) was one of the first prominent physicists to propose that reality might not be wholly physical, in some sense, our cosmos must be a “participatory” phenomenon requiring the act of conscious observation — and thus consciousness itself. Wheeler also drew attention to implicit connection between physics and information theory, which was invented in 1948 by mathematician Claude Shannon. Just as physics builds on elementary particles, the quanta, defined by measurement, so does information theory. Its “quantum” is the binary unit, or bit, which is a signal represented by one of two choices: yes or no, plus or minus, zero or one. With his famous “it from bit” concept he unites quantum information theory to consciousness and physics.
While Wheeler emphasized bits at his time, it appears that intrinsically quantum-mechanical forms of information – now known as ‘qubits’ – are even more fundamental. In recent years a rising number of theorists have been exploring whether these curious quanta of information may hold the answer to combining quantum theory and general relativity into a quantum theory of gravity.
If we are to reason for the non-dual picture of the world then quantum physics is directly linked to consciousness. The human brain is a physical organ that transmits and interprets electrochemical signals. Its biochemistry is certainly governed by quantum physical laws, and consciousness — which is clearly related to the functioning of the brain — must therefore be related to the quantum physical processes going on within the brain and in the cosmos at large.
