Question

hi,
I am expressing protein with Unnatural Amino acid (UAAs) especially negatively charged UAAs. i am trying different -ve UAAs they were easy to incorporate in protein and gave good expression. But the problem is with sTyr (Tyrosine-O-Sulphate).
Previous, research reported that exogenous styr shown low permeability and the other possible reason is to can't compete with endogenous sTyr.
Different strategies were successfully applied for sTyr incorporation for instance
(1) Propeptide gateway (doi: 10.1038/nchembio.2405)
(2) Engineered periplasmic binding protein (PBPs) to accelerate the UAAs transportation (DOI: 10.1021/acssynbio.9b00076).
So, i am seeking your expertise and possible solution, is there any other way to enhance like chemicals methods (detergent (Triton-X or Tween 20), DMSO, EDTA, or EGTA for transportation? Because above method will take too much time and resources as well.
But i am confused and unable to figure-out either are these safe for recombinant protein expression? Because my protein yield is already low with this sTyr.
One more thing, i also used 2% EtOH as mentioned following articles (
this increased the protein expression with very low sTyr mutant yield.
Please am looking forward your valuable suggestion.
Thanks,

Can anyone please suggest whether we can transfer these cell lines at a temperature of -20 degree Celsius? In addition to that, does this transportation at -20 affect the cells growth pattern?
Relevant answer
Answer
Hello Sanjay Kumar,
The cell lines aren't recommended to transport at -20 degree C as it will kill the cells due to the cold injury. The addition of cryoprotectants may not help as well. We have developed a new live cell shipping solution that can be used to ship cells at ambient temperature for 5-7 days. It is simple and the cells can be shipped inside a small bubble mailer via regular courier thereby reducing the shipping cost significantly.

I suppose there have been questions of this kind, but I do not know how to find them. (Maybe somebody can tell me.)
A task: to transport one ton (1000 kg), at the distance of 100 km, by sped of 100 km/h.
How much pollution is produced, and how much energy is spent to perform this (or similar) task by: (1) steam locomotive, (2) electrical car?
In case (2), the pollution must include the production and decommissioning of batteries, as well as the fact that most electricity is produced by fossil fuels (such as coal). The consumption must include all the losses of energy in transformations, from the power plant to batteries, and from the batteries to electrical engines in the car.
Clean vehicles are surely good for cities, but I do not know how good they are for the planet.
Relevant answer
Answer
Clean vehicles, such as electric and hybrid cars, are generally cleaner than traditional combustion-engine vehicles because they produce lower emissions. However, their environmental impact depends on factors like the source of electricity for charging and the lifecycle of the vehicle's materials.

What is the latest research progress of adaptive signal control system in the field of transportation?and I feel that if it is just to improve efficiency, it is meaningless.
Relevant answer
Answer
I think Adaptive signal control systems (ASCS) bring several benefits, including improved traffic flow, reduced congestion, and decreased vehicle emissions, which collectively enhance urban mobility and environmental quality.
However, these systems also face challenges, such as high implementation and maintenance costs, privacy concerns related to data collection, and the potential for technological failures that could disrupt traffic rather than streamline it.
These technologies thus present a balance of significant improvements in efficiency and safety, with substantial considerations in terms of cost, privacy, and dependability.

I am trying to develop some recommendations about how to use TNFD, TNFD-LEAP, SBTi, SBTs for Nature in business performance for transportation sectors. It is difficult to give a simple relationship map among these and I wonder if any advice for me to nevigate these?
Relevant answer
Navigating the landscape of sustainability frameworks and initiatives can indeed be complex, but here's a breakdown of the relationships between TNFD, TNFD-LEAP, SBTi, and SBTs for Nature, along with some advice on how to use them in business performance for the transportation sector:
  1. TNFD (Task Force on Nature-related Financial Disclosures):TNFD is a global initiative that aims to provide guidance to organizations on how to assess, manage, and report on their dependencies and impacts on nature. It focuses on integrating nature-related risks and opportunities into financial disclosures, similar to how TCFD (Task Force on Climate-related Financial Disclosures) addresses climate-related risks and opportunities.
  2. TNFD-LEAP (TNFD Leadership for Environment and Profit):TNFD-LEAP is likely an extension or a specific program under TNFD aimed at encouraging leadership in integrating nature-related considerations into business strategies with a focus on driving both environmental and financial performance.
  3. SBTi (Science Based Targets initiative):SBTi is a collaborative initiative that helps companies set science-based targets to reduce greenhouse gas emissions in line with the Paris Agreement's goals. While SBTi primarily focuses on climate-related targets, it could indirectly influence nature-related targets by encouraging companies to adopt practices that reduce their overall environmental footprint.
  4. SBTs for Nature (Science Based Targets for Nature):SBTs for Nature is a relatively new initiative that, like SBTi, aims to set science-based targets but specifically for addressing biodiversity and nature-related impacts. These targets are likely designed to complement existing climate-related targets by addressing broader environmental concerns beyond just greenhouse gas emissions.
Advice for Navigating:
  1. Understand the Intersections: While each initiative focuses on different aspects (financial disclosures, climate targets, nature-related targets), there are overlaps and synergies between them. For instance, integrating nature-related considerations into business strategies could align with both TNFD and TNFD-LEAP objectives while also supporting the broader goals of SBTs for Nature.
  2. Integrate into Sustainability Strategy: Consider how these initiatives can complement each other within your organization's sustainability strategy. For transportation sectors, this might involve setting science-based targets for reducing emissions (SBTi) while also integrating measures to minimize impacts on biodiversity and ecosystems (TNFD, SBTs for Nature).
  3. Collaborate and Learn: Engage with relevant stakeholders, industry peers, and experts to understand best practices and emerging trends in sustainability reporting and target-setting. Collaborating with organizations already involved in these initiatives can provide valuable insights and guidance.
  4. Customize to Context: Tailor your approach to the specific context and challenges faced by the transportation sector. Consider factors such as the type of operations (e.g., air, road, rail, maritime), geographic locations, and supply chain dynamics when developing recommendations and setting targets.
By understanding the relationships between TNFD, TNFD-LEAP, SBTi, and SBTs for Nature, and applying these insights to your business performance strategies, you can effectively navigate the sustainability landscape and drive positive environmental and financial outcomes in the transportation sector.

Question
1 answer
A large percent of of crude oil is consumed by transportation sector globally .
By referring to previous years statistics , more than 60 percent of worldwide oil consumption
belonged to transportation sector .
Corona virus pandemic mainly struck the travel and public transportation industry
in short term , that are part of transportation sector .
So the question may ensue the following questions :
- How many percent of oil consumption belonged to travel and public transportation industry ?
- How many percent the travel and public transportation industry is struck by pandemic in monetary term ?
- And how many percent of travel and public transportation industry costs is allocated to fuel (mostly crude oil products) consumption .
Can anyone introduce some references ?
Relevant answer
Answer
The impact of the coronavirus pandemic on crude oil consumption has been significant, particularly in the short term. Here are some insights and references to help answer your questions:
  1. According to the International Energy Agency (IEA), transportation accounts for about 60% of global oil consumption. Of that, around 25% is used for passenger cars and light-duty vehicles, while the remaining 35% is used for heavy-duty vehicles, aviation, and marine transport.
  2. The travel and public transportation industry has been severely impacted by the pandemic, with significant declines in both passenger traffic and revenue. According to the World Bank, the global tourism industry is expected to contract by 70% in 2020 compared to the previous year. The aviation industry has also been hit hard, with a decline in passenger traffic of around 60% in 2020 compared to 2019.
  3. The share of travel and public transportation industry costs that is allocated to fuel consumption varies depending on the mode of transportation and the location. In general, however, fuel costs can represent a significant share of total operating costs. For example, in the United States, fuel costs can represent up to 30% of total operating costs for the trucking industry.

For testing the design safety of hydrogen tanks, standards like ISO 15869, EC79, JARI 2002, KHK S0128, etc. are usually preferred. However, for transportation of these tanks TPED, DOT, TC/UN, KGS, JIS, etc. certification needs to be obtained. Can anyone explain that what are the tests which the tank will need to pass for TPED certification?
Relevant answer
Answer
The tests that are required for TPED certification of hydrogen tanks include: * Pressure Test: A pressure test is performed to check the integrity of the tank and to make sure that the tank can withstand the maximum pressure it is designed for.
* Impact Test: This test is to check the resistance of the tank to impacts and vibrations.
* Leak Test: The tank is tested for any leaks or defects in the welds.
* Thermal Test: The tank is tested for its ability to withstand extreme temperatures.
* Drop Test: This test is to check the stability of the tank when it is dropped from a certain height.
* Burst Test: This test is to check the integrity of the tank when it is subjected to igh pressure.

Hi,
We recently started a project on the analysis of planktonic bacterial populations (DNA and RNA based analysis) in a series of lagoons of diferent contions. We have filtered samples using sterivex filters and frozen them in liquid N2 for transportation. Now stored at -80ºC.
For DNA extraction we generally brake the filter cage, cut filter into pieces, and extract using DNeasy Power Water kit.
I'm looking for alternatives for a separate RNA extraction or a DNA/RNA coextraction. Does anyone have experience on this and can share some tips/protocols?
Best wishes

Electric vehicles (EVs) are now widely regarded as mature and promising for the future of mobility. As the markets expand, the next battery technologies are being marketed as a miraculous answer for the energy transition to zero-emission automobiles. EVs are seen as the silver bullet for end-user electrification and a major weapon for combating global warming, allowing us to shift without having to change any of our lifestyles or mobility, which are based on the private car. Unfortunately, the electric vehicle is not a clean or carbon-free technology. Is there a future alternative to our current mode of transportation? How will knowledge and cutting-edge technologies change and solve our transportation problems?
Relevant answer
Answer
The answer is yes. Electric vehicles are a very promising area of ​​development and will see tremendous growth in the coming years. This long-awaited growth process is due, in large part, to the reduction in the load of environmental damage that this type of artifact produces in the first place.
It cannot be determined from now on how long electricity in transport will be a sustainable solution because from now on technological changes will occur at an increasingly accelerated rate, which will contribute to generating new and unexpected proposals for solutions.
The current problems that make electricity viable for public transport are also based on the wide possibilities of mass movement of people in all directions and in all countries that can take on this challenge.
The irregularities of the land are solved with the construction of tunnels and this helps in a satisfactory way to take advantage of the spaces and optimize the routes of the vehicles, that is to say that the use of the vehicle itself is not everything, it is also about investing in infrastructure .
The infrastructure, of course, is also an expense because if you only have vehicles and you don't have roads, good railways, airports or cable cars, then you simply won't have how to use these means.
Humanity belatedly began to enter the use of electrical energy in public transport but, finally, it seems that we are going down that path, other solutions will come later, but what is in the short term, we all know that it is an inevitable fact.

The boundaries of my investigations limits by real implementation on cities which are too far from driverless cars, ITS or other hyperllops-like decisions. I carefully examined,perhaps, all the existed models and approaches from japanees "Jamology", limitations of transport flows in the centre (of London,tax model), VANET, platooning, V2X, SCATS, SCOOT, traffic lights management and other methods which have some limitations from 'non detected' [without any sensors] vehicles (old cars, mini bus taxies or so-called "root taxy" , horses and carts , motocyclies, scooters, etc. or the bypass roads (which have exits in the centre of calculating zone and make some deviations in algorithms).
Not everything is solved by the development of public transport. In our city, it is planned to build a subway for 20 years, but the zones of the city are developed according to their own laws without taking into account the plans laid down for the metro, and therefore part of the dug canals under the ground do not meet today's needs.
Similarly, with the development of cycling and pedestrian zones. In countries with sharply continental weather in the cold season, it is unlikely that the city dweller will choose a bicycle instead of his personal car while the temperatures below 20 °C. Bus routes can have a certain effect, but again, dedicated lanes are needed (consider adjustments to the law and traffic regulations) and the replacement of a fleet for more comfortable trips as well as more developed routes. Inspection of road regulation(the police) is not as much interested in solving the problems of traffic congestion. The main indicator of the success of their work is the minimum number of accidents and victims on the roads. Therefore, the lower the traffic flow rate or its "standing", the calmer. Thus, what solution can really be implemented in cities where there are no autonomous and flying cars, where the budget is not enough to build monorails and tunnel stations (junctions) to connect metro, buses and other vehicles in rooms with comfortable conditions (for example, Queensland , New Zealand)?

A tachograph is a device fitted to a vehicle that automatically records its speed and distance, together with the driver's activity selected from a choice of modes. The drive mode is activated automatically when the vehicle is in motion, and modern tachograph heads usually default to the other work mode upon coming to rest. The rest and availability modes can be manually selected by the driver whilst stationary.

Question

At root MMT is commonly, and rightly, encapsulated by J Fagg Foster's insight, "Whatever is technically feasible is financially possible." Foster's brilliant understanding has been developed by MMT. MMTs most general conclusion is that government deficit is not, granted certain conditions, in itself, to be avoided, at least as an a priori. The question that I find myself left with is, advocating and having developed into another, a key insight, what is MMT?
Before going further, however, there remains a meta-issue: A common rejoinder by MMT defenders to critique is that the corpus of MMT literature contains a counter to how they are themselves being described, rendering the critic's argument as resting essentially on a straw man fallacy. Is this a valid defense? Must one read every publication, post, and other public statement of MMT to be able to authentically criticize it? Does MMT hold one consistent, though complex it may be, and reasoned point of view? Is MMT immune from having to post a clear statement of what it stands? Such a statement is offered, I will admit only to some degree, by Microeconomics in their textbooks; John Maynard Keynes (again I will admit with considerable controversy), Milton Friedman, and Robert Lucas are often readily and succinctly paraphrased, with, as far as I am aware of, little defensiveness from their advocates. Could MMT be said to be engaging in a defense of obfuscation?
To begin to ask my questions of MMT itself, is MMT an argument for full employment, or is it in argument for the feasibility of government social programs, or is it an argument for both? It has been said, at least somewhere in the MMT "literature," that MMT policy shall never be carried out at Full Employment. If this is the case, than at full employment, is MMT clearly asserting that social programs that require any workers, at least without a change in immigration policy, are not possible? And what does "full employment" mean? Is any government program to be "green lit," other things being equal, if only one worker is unemployed? If only one worker is out of the work force, yet able and willing to work, does this imply that any government social program is possible? Does this make any sense? Or is MMT arguing that no social program requiring more workers than are unemployed or willing and able to work, yet out of the work force, be used by a government program? Is available unemployed an established capacity limit to government programs argued by MMT? Is it suggesting that the quantity of available workers, with, or trainable, acknowledging the time lag implicit in this, be measured by any and all potential government programs, and that sufficient, in time, worker availability be established before its implementation be advocated? Is it clearly understood by MMT that levels of unemployment in itself are a restraint on government social programs. And without agreeing that frictional or structural unemployment exists, what is MMTs counter to the claim that they do? If unemployment does exist at a "natural" rate, than would not government policy be altering the nature of aggregate supply and risk creating an inflation that is not remediable by taxation by increasing the hiring of those who might be "naturally" unemployed?
Absolutely in How to Pay for the Green New Deal, by Yeva Nersisyan and L. Randall Wray (2019), as at least an example, by relying largely on proposed resource savings from the implementation of Medicare for All, it is argued, albeit in terms of GDP, not number of workers per se, it is argued that resources be rearranged so that, few, or even no, new resources, i.e. job vacancies, need be created to operationalize the GND, though the lead author has confessed at the ICAPE conference of 2020 that the paper makes no claim as to what the GND is, begging the question, "How can an explanation for the funding of a program be reasonably carried out if you do not know what that program is and (thus) the resource use that it will involve?"
The question, however, remains: is the solution that MMT is consistently offering to a full employment-social program conundrum that labor be relocated (and retrained) from other sectors? Is the established MMT argument, at least in light of How to Pay for the Green New Deal, in response to "full employment" that programs are possible if resource capacity can be altered by transferring jobs (and retraining), such as How to Pay for the Green New Deal might suggest? Is MMT consciously acknowledging that a resource scarcity in terms of labor in the assessment of the feasibility of government social programs be met with job transition? Has it considered adequately the possibility of opening immigration, including transportation, housing, and training to those in poverty around the world to work on government programs in the United States or other "MMT countries", given such a labor shortage at home? Economics often equates capacity with labor, but might there be more to capacity than labor-is employment the only measure of capacity?
As to social goals and the federal job guarantee, if there were a federal job guarantee (FJG) and this is indeed central to MMT, is it tied to the fulfillment of government social goals fulfilled by government programs; i.e. is the argument that desired social programs must be tied to the federal job guarantee such that any new labor demand created by government will be exclusively sourced from the job guarantee, or is it that non-FJG jobs required to fulfill government program goals will be at a greater wage than the FJGs fifteen dollar an hour wage and will draw labor (exclusively?) from FJG programs? IF not, given a greater than the FJG wage, are the consequences of reducing employment in the private sector to staff government projects being adequately considered?
Though considerable explicit and implicit controversy exists about the environmental impact of economic growth, partially (or fully? Is this possible at this time?) green or otherwise, a question emerges concerning MMT policy in terms of raising wages, and even employment, through the FJG or through the implementation of even green social programs. Assuming that due to imports, growing Kapitalization, and/or industry structure, inflation does not occur as a result of MMT policy, what is happening to the Earth? Is it possible, if not likely, that new housing starts, imports from cheaper dirty foreign economies, and increased real goods demand in other sectors will negatively impact the environment? Every new home is at high risk of destroying animal or plant habitats, wetlands or other ecological systems, and landscapes-even homes that produce no GHG emissions. Every new automobile, even if 100% electric, involves possible lithium mining, ore mining, paints, and the resources necessary to manufacture it, not to mention a variety of other resources such as, perhaps, plastic and vinyl. This does not include the increased resources, even "green" used to power it. This is also true of much, if not most, other consumption goods that upticks in labor demand and/or wages are likely to bring on. In addition, without claiming to be such an advocate, as brought up by nuclear energy advocates, if not others, is the significant environmental impact of wind and solar. More energy demand, even if entirely green, means more negative environmental impact. In theory, it is true that through recycling, using land already destroyed, and by placing high taxes and/or bans on much material consumption, much of the negative environmental impact of economic growth might (or might not) be averted, but does MMT policy, i.e. social programs, including the Federal Job Guarantee clearly, and unequivocally, count the Earth's resources as element of capacity?
So far, and it is quite possible that I am not aware of aspects of the MMT literature that says otherwise, the only real measure of capacity that has been put forward by MMT is inflation. Given no shortages, overutilization of current capacity could well be hidden by stable prices. Most horrifyingly of capacity overutilization is in surpassing environmental sustainability for both for the current generation and the next- the destruction of the Earth! And if there were inflation, is MMT arguing that we increase taxes in response, resulting in workers finding that their newly increased wage is buying less than they had hoped? Would MMT respond to their concern by telling them that this isn't a problem because in the long-run inflation will reduce and taxes will decrease? Is it understood that given government's trying to avoid a given level of inflation, no new social programs are possible until inflation returns to normal, and if it does, is it reasonable to assume that immediately engaging in another government project will not almost immediately cause another inflation spike that must be met with another round of taxes? Given inflation and the taxes intended to fight it, would the value of the minimum wage continue to make it a living wage?
It is my opinion that MMT has developed a key insight into government policy first suggested, as far as I know, by J Fagg Foster. MMT has brought to our attention the fact that the issue is not "money" or financial cost, but the quantity (and quality?) of available capacity. From here, MMT might be in need of more profound development.
What I argue is that MMT is fundamentally an institutionalist offshoot, not that it is not deserving of its own distinct name, but instead that it must take a starkly institutional approach to economics-to capacity-and to what capacity is and can be. In short, instead of arguing that inflation is an adequate measure of overcapacity,* it is better argued that capacity is measurable by existing, better-developed, empirical means. An idea would be that the massive abilities of econometric analysis, machine learning, and neural networks currently available to us, be used to measure capacity in physical, real, terms. The number of workers actually available or that could be transferred from other jobs; the ability based on, at least, for example, survey data, for them to be relocated or retrained; and what the changes in their real earnings as a result is, is measurable, and needs to be...measured.
The assumption that future technologies will be able to improve the environmental sustainability of current consumption is not a reasonable one. Moore's law has come to its predicted end and it is widely agreed that technology "bubbles" are stochastic in their arrival. We cannot reasonably assume, risking the health of the Earth, and the ability of future generations to subsist upon her, that Earth-health is not relevant to capacity. Therefore, capacity must include environmental sanctity in its measure. I will term such a capacity measure, REAL capacity. Policy must be carried out involving honest and careful conversation with Ecotoxicologists, Climate Scientists and Biologists and in fully incorporating what they say into policy. Though likely this is only a beginning to assessing environmental impact, MMT must soundly acknowledge that non-human resource use, autonomous to it money-price, is a key element of capacity and that, permanent inflation above wages, rent, and profit rises to match, is nothing but a good thing for the Earth, as it will keep such resource use, at least partly, in check.
In short, environmental sanctity is an element of capacity, that is at risk of going unnoticed. The occurrence of a leakage to it is generally counter to that of any inflation indicator: dirty imports might well keep inflation in check, but will not have the same effect upon the environment, which they will increase the damage ot. Domestically, increased "economies" of scale and/or an increased number of suppliers, might keep long-run, at least, inflation in check, but will not stop, for example, new housing starts in response to increased demand for housing from further harming the environment.
Research and wide discussion is necessary to discover how to take people out of poverty without harming the environment-how to communalize and how to reduce housing size and organize work site location (from at "home" wherever possible, as an example) such that reasonable subsistence is realized and environmentally harmful resource use is eliminated. This is more than just an interdisciplinary imperative, it is a public one. Few people likely do not have at least something to contribute as to how make the most efficient (in REAL terms) use of resources.
If resources use is to be increased, or even maintained, any assumption that foreign exporters will somehow magically decide to green or that technology will somehow magically be created and implemented to allow us to consume as we were without environmental impact, must be discarded. If these phenomena arise, then they can perhaps be relied upon and included in REAL capacity measurement. If the introduction of government programs (or otherwise), green or not green as they may be, increases consumption, a full survey of the costs and possibility for their sufficient reduction must be realized. If the result of this survey, when honestly interpreted, suggest a negative environmental impact, then the capacity to carry it out, as it stands, simply is not there.
If it argued that consumption in a program can be altered to make it non-environmentally harmful, then this fact must be firmly established. For example if it is argued that imports will limit inflation given the excess demand (or diminished supply) caused by a government program, then international agreements that require adequately green production abroad, ensuring no increased non-renewable resource use, including enforceable penalties for violations that impose more cost on violators than adherence to the agreement, have to be in place. Consumption restriction and substitute-supplementation with sufficient green goods (and/or services) must be such that consumption of only renewable resources will occur with increased incomes. If implementing the program in accord with environmental sanctity might result in decreased consumption per change in income than had been imagined, then this fact is best disclosed.
The difficult challenge of allowing all of humanity to live well enough to be (able to) be happy while no longer destroying the Earth in the process needs to be met. A tremendous amount of creativity and ingenuity, informed by A.I. technology needs to be our is available to us, and utilizing this must be our intention. Utilizing these resources will lead to the most efficient outcome. Spending on chosen programs until inflation hits, hoping for an economic crises to free up workers for social programs, and confusing reality with hope about our ability to substitute green production is not an answer. A near infinity of answers are, however, available to us. These range from Thorium power plants to Iron Salt Aerosols to sequester methane, to Paul Hawken's Drawdown to significantly reduce global greenhouse gas emissions. The emphasis needs to be on accurate technical measurement of REAL capacity, on human creativity & ingenuity, and on faith in society-wide acknowledged spirit. As I'm sure MMT advocates of all people would agree, we cannot put faint in monetary measures to evaluate, let alone to expand capacity.
Even if the costs to measuring REAL capacity, and to innovating its expansion are high, the costs of not doing so is far greater.
*MMT literature, especially as a fledgling school in the 1990s, argues that inflation is a largely counter-cyclical phenomenon and is instead largely a function of "social pricing." Given that this is true, is inflation sensitive enough to overcapacity to adequately measure it? If the answer is yes, then MMT is engaging in a contradiction as to the nature of price rises.

Thank you for your response and article inclusion. Please note from my discussion post the statement: "Most horrifyingly of capacity overutilization is in surpassing environmental sustainability for both for the current generation and the next- the destruction of the Earth!" The article that you linked states: "In this regard, equitable and inclusive growth is the real agenda of development, also known as sustainable development [emphasis added]." This is a use of "sustainability" that may be meant to imply, but does not consider, environmental sustainability. As far as I am concerned, reducing poverty / increasing equality is simply grasping for "low fruit" (i.e. relatively easy) in light of the need to end poverty universally while also using no imperfectly substitutable non-renewable resources. Ending poverty as such is the "high fruit" or real challenge of economic research. I find the use of the term "sustainability" as defined by ji et al. (2021); Sachs (2012); Umar et al. (2021) as cited in Niaz (2021) too misleading to be reasonably used outside of meaning "strong sustainability" where the natural environment–non-renewable resources or at least perfect substitutes too them–are infinitely sustained.
I am afraid that "equitable and inclusive" growth completely and misleadingly neglects environmental concerns which themselves are only spuriously addressed by (weak sustainability) arguments themselves. These arguments assume that GDP growth will outstrip GDP decay as environmental damage increases with GDP growth. Any assumption that growth in human welfare outside of GDP can involve non-perfectly substitutable environmental destruction, whether it reduces poverty or income inequality or both, is essentially spurious. As I am currently researching, "strong sustainability" is a lie: it is ignoring the rising marginal disutility of non-market environmental-damage creation which will occur, as explained by the foundational principles of microeconomic theory, at a constant to increasing rate. A constant–to–rising marginal quantity of bad creation as a function of GDP or any other form of material good creation, results, therefore in a limit to welfare growth as a function of GDP growth. This limit exists where the falling marginal utility of material good creation equals the rising marginal cost of its bad creation. It seems to go almost without saying that negative population growth is of the highest priority in increasing the limits to per capita GDP growth. Without total suppression of environmental bad creation that increases in physical quantity with material goods growth, such growth cannot exist without a welfare optimum, i.e. a real limit to GDP growth, one that we may already be living outside of where the Marginal Cost of material growth is and will continue to be increasingly greater than its Marginal Benefit.
This suggests a material goods production drawdown and redistribution; a microcredit proposal, other things equal, involves neither.

Hi!
Does anyone have experience of shipping extracted total RNA at ambient temperatures, for RNA seq;
(i) using DNA/RNAshield using Zymogen? (or recommend an alternate product. RNAstable has been discontinued)
(ii) ethanol precipitated RNA (ethanol, 3M sodium acetate)?
Thanks!

Hi Mehdi,
I have transported RNA at ambient temperature for sequencing and works good. Firstly, I precipitated with of 0.1 volumes of 3 M sodium acetate (pH 5.2), 2.5
volumes of ethanol and 2 μl of glycogen (10 mg/ml) (ON). Secondly RNA was centrifuged at 14,000 g for 30 min at 4C, washed in 75% ethanol and dried in speed-back. Everything has to be RNAase-free.
Other options are RNA later or RNA Transport.
Good luck!

In a world where environmental concerns are stronger than ever, it makes sense to "clean up our act" across all industries including transportation, but biofuels will not be a good contemporary to electricity among other alternative fuels as it would exacerbate the "food vs. fuel" conundrum; we do not want to incentivize further environmental destruction. At the same time, we must also put our ways of doing so into consideration (e.g., mining for battery materials). I have mentioned the case for synthetic fuels as a complementary to BEVs in an article published on an aeronautics-themed issue on NAE's "The Bridge" (The article is the last one on the cover, and you can jump to it by clicking the article title "Putting Out Fire... with Gasoline? A Pragmatic Path toward Clean Fuels"). These types of fuels are already being tried in the aviation and maritime shipping industries, and is just getting ready for motorsport applications, but this also leaves us asking a big question: could they just be as viable for the transportation industry?
For the record, I acknowledge that BEVs will soon surpass internal combustion engine-powered vehicles in emissions, cost-effectiveness, range, and fueling time. For example, when we ramp up battery quality and production to be able to make solid-state batteries that could eventually provide thousands, if not millions of miles in range. However, we should also consider the ways ICEs can coexist with them yet have the upper handle, such as:
Maintenance: Yes, while BEVs/FCEVs have fewer moving parts than ICE-powered vehicles, the maintenance advantage for the latter is not what you think. It is natural for batteries to degrade, especially when used for prolonged periods of time, and experts recommend to only use between 20-80% of range to minimize the amount of stress put onto it. On the other hand, for ICEs, it is suggested to always leave the tank at least 1/4 full to minimize the likelihood of damage to the fuel tank and pump. While you could fully fill up your tank (as condensation could otherwise affect the lifespan of the fuel tank), it is not a good idea to "top it off," either. That is pouring a little bit more fuel into the tank when the pump cuts off, generally to round the cost of the refuel to the nearest dollar due to the risk of damage. Experienced truckers will only fill up to 95% full given that the fuel expands in heat alongside the risk of spillage and generally go no faster than 65 mph to maximize efficiency.
Accessibility: Suppose you are in a wildfire-prone area like California and a blackout affects your area. Before this happens, you may need to plan ahead as unless you have a generator or the like, you may be stranded while the gas stations hang on a little longer despite the increased traffic. Synthetic fuels would mean that environmental compliance would be just a retrofit away, and, in Porsche's case, the engines do not need modifications, either.
Fuel Economy in cold weather: I have seen conflicting reports on BEVs' fuel economy in cold weather. While many sources say that gasoline's drop is less than that of hybrids and BEVs (e.g., https://www.fueleconomy.gov/feg/coldweather.shtml), thermal management technologies, which can also be found in modern-day ICEs, can say otherwise, so it effectively depends on the battery/vehicle.
Availability of resources: To have as much as a resilient global energy supply as possible, we should not throw all of our eggs into one basket. While bidirectional charging, could, in theory, allow for a perpetual expansion of our electric grid, we must take the availability of resources into consideration, and must diversify our materials in case of supply bottlenecks. The second aspect mentioned above also falls under this umbrella, too.
In addition, we must also find ways to make the process of such synthesis of fuels much more efficient while at the same time bringing the cost down. This MIT-developed battery captures even atmospheric CO2 and is about to be tested at Porsche's synthetic fuel plant down in Punta Arenas at the extreme southern region in Chile's Patagonia: https://news.mit.edu/2019/mit-engineers-develop-new-way-remove-carbon-dioxide-air-1025 & https://news.mit.edu/2020/new-approach-to-carbon-capture-0709
However, most of the synthetic fuels about to be produced in a commercial scale are essentially made of recycled carbon so these specific types of fuel will be unviable in the long run. However, there seems to be room for improvement.
There is no doubt that EVs and alternative fuel cars are here to stay and will inevitably outpace traditional "ICE" engines in terms of sales and production, but when we take these advantages in consideration, how we could improve synthetic fuel to make production easier, cleaner and more efficient, and make it release as little emissions (CO2, NOx, etc.) as possible, if any? Oxy-fuel technologies? Technological breakthroughs once thought inconceivable years, months, or even weeks ago?. Maybe Porsche, BMW, Mazda, et al. could get some help.

Answer
Dear Mikhail,
sorry to see that your very interesting technical question has not yet received any expert answers. We are synthetic inorganic chemists, so I'm certainly not an expert enough to provide you with a qualified answer. All I know is that MEHQ (= methylhydroquinone or p-methoxyphenol) is thermally rather stable as it has a boiling point of 243–244 °C at normal pressure. According to the manual cited below it is important to maintain a certain oxygen content. As soon as all oxygen is consumed, the inhibitor will lose its activity and the polymerization of n-butylacrylate can start. Thus the inhibition effect of MEHQ can only be operative in the presence of sufficient oxygen. For more detaild information please have a look at the following handbook:
SAFE HANDLING AND STORAGE OF ACRYLIC ESTERS
