New study confirms extensive gas leaks in the North Sea

"The positions of the boreholes and the location and extent of the gas pockets indicate that this area of the North Sea alone has the potential to emit 900 to 3700 tonnes of methane every year. 'However, more than 15,000 boreholes have been drilled in the entire North Sea,'

"In the North Sea, about half of the boreholes are at such shallow water depths that part of the emitted methane can escape into the atmosphere."

In cell studies, seaweed extract outperforms remdesivir in blocking COVID-19 virus

"But the virus could just as easily be persuaded to lock onto a decoy molecule that offers a similar fit. The neutralized virus would be trapped and eventually degrade naturally.

Previous research has shown this decoy technique works in trapping other viruses, including dengue, Zika, and influenza A.

Reversing a model of Parkinson’s disease with in situ converted nigral neurons

One-time treatment generates new neurons, eliminates Parkinson's disease in mice

"Researchers have discovered that a single treatment to inhibit a gene called PTB in mice converts native astrocytes, brain support cells, into neurons that produce the neurotransmitter dopamine. As a result, the mice's Parkinson's disease symptoms disappear. "

"The treatment works like this: The researchers developed a noninfectious virus that carries an antisense oligonucleotide sequence -- an artificial piece of DNA designed to specifically bind the RNA coding for PTB, thus degrading it, preventing it from being translated into a functional protein and stimulating neuron development.

Antisense oligonucleotides, also known as designer DNA drugs, are a proven approach for neurodegenerative and neuromuscular diseases "


A War Against Climate Science, Waged by Washington’s Rank and File

Efforts to block research on climate change don’t just come from the Trump political appointees on top. Lower managers in government are taking their cues, and running with them.

"survey in 2018 of more than 63,000 federal employees across 16 agencies identified the E.P.A. and Department of Interior as having the least trustworthy leadership in matters of scientific integrity.

Findings published in the peer-reviewed journal PLOS ONE in April on a subset of those agencies found that 631 workers agreed or strongly agreed that they had been asked to omit the phrase “climate change” from their work. In the same paper, 703 employees said they avoided working on climate change or using the phrase."

Great paper on easy nano grain CO2 catalyst, made by simple flame pyrosis. Easy and scalable, this can create a flexible syngas product, and you can "dial" in the CO and H quantities to make fuels or plastics.

This could get rid of oil and gas production in a year or so..... especially if we started switching over to methanol and electric right now, and not subsidizing fossil fuel cars and companies anymore.

"It means it can be used industrially, it can be scaled, it’s super quick to make the materials and very effective,” she says.

“We don’t need to worry about complicated synthesis techniques that use really expensive metals and precursors – we can burn it and in 10 minutes have these particles ready to go. And by controlling how we burn it, we can control those ratios of desired syngas building blocks.”

"“The idea is that we can take a point source of CO2, such as a coal fired power plant, a gas power plant, or even a natural gas mine where you liberate a huge amount of pure CO2 and we can essentially retrofit this technology at the back end of these plants. Then you could capture that produced CO2 and convert it into something that is hugely valuable to industry,” says Dr Lovell."

The researchers say in effect, they are closing the carbon loop in industrial processes that create harmful greenhouse gases. And by making small adjustments to the way the nanoparticles are burned by the FSP technique, they can determine the eventual mix of the syngas building blocks produced by the carbon dioxide conversion.

“At the moment you generate syngas by using natural gas – so from fossil fuels,” Dr Daiyan says. “But we’re using waste carbon dioxide and then converting it to syngas in a ratio depending on which industry you want to use it in.”

For example, a one to one ratio between the carbon monoxide and hydrogen lends itself to syngas that can be used as fuel. But a ratio of four parts carbon monoxide and one part hydrogen is suitable for the creation of plastics, Dr Daiyan says.

Universal and reusable virus deactivation system for respiratory protection

"Here, we report the development of a universal, reusable virus deactivation system by functionalization of the main fibrous filtration unit of surgical mask with sodium chloride salt. The salt coating on the fiber surface dissolves upon exposure to virus aerosols and recrystallizes during drying, destroying the pathogens. When tested with tightly sealed sides, salt-coated filters showed remarkably higher filtration efficiency than conventional mask filtration layer, and 100% survival rate was observed in mice infected with virus penetrated through salt-coated filters. Viruses captured on salt-coated filters exhibited rapid infectivity loss compared to gradual decrease on bare filters. Salt-coated filters proved highly effective in deactivating influenza viruses regardless of subtypes and following storage in harsh environmental conditions."

"It seems that whatever “crap” we put into graphene, electrocatalysis increases.(2) One may exaggerate only a little by saying that if we spit on graphene it becomes a better electrocatalyst. Having 84 reasonably stable elements (apart from noble gases and carbon), one can produce 84 articles on monoelemental doping of graphene; with two dopants we have 3486 possible combinations, with three dopants we can publish 95,284 combinations, and with four elements there are close to 2 × 106 combinations."

"We decided to follow the hyperbole of ever multiplying dopants; however, instead of using expensive and toxic chemicals such as ammonia, fluorine, chlorine, boranes, etc., we took a page from the pre-Haber–Bosch era and sought natural materials for the fertilization of graphene and used guano as a dopant. Guano has a great advantage for doping over using synthetic chemicals. It is available at low cost, it contains a plethora of elements (including N, P, S, Cl, etc.), and its use for graphene doping can be handled by a nonchemist. We show that we can create high-entropy, multiple-element-doped graphene with outstanding electrocatalytic properties for two industrially important reactions: oxygen reduction used in fuel cells and hydrogen evolution used in electrolyzers. If we follow the claims of previously published doped graphene for electrocatalysis articles regarding “metal-free catalysis”, one can envision an era in which guano-doped graphene is used instead of platinum in fuel cells and electrolyzers, with huge societal impact not only in clean energy production and a cleaner environment but also on rural economies as guano once again becomes a valuable and highly sought-after product."

2019 Corona virus has 4 inserts that match HIV, showing possible bio-hacking.

Uncanny similarity of unique inserts in the 2019-nCoV spike protein to HIV-1

" The  finding  of  4  unique  inserts  in  the  2019-nCoV,  all  of  which  have identity  /similarity  to  amino  acid  residues  in  key  structural  proteins  of  HIV-1  is  unlikely  to  be fortuitous in nature. This work provides yet unknown insights on 2019-nCoV and sheds light on the evolution and pathogenicity of this virus with important implications for diagnosis of this virus.  ".

Unexpectedly, all the insertions got aligned with Human immunodeficiency Virus-1 (HIV-1). F

"As none of these 4 inserts are present in any other coronavirus, the genomic region encoding these inserts represent ideal candidates for designing primers that can distinguish 2019-nCoV from other coronaviruses".

"This  indicates  that  these  insertions  have  been  preferably  acquired  by  the  2019-nCoV, providing it with additional survival and infectivity advantage. Delving deeper we found that these insertions were similar to HIV-1. Our results highlight an astonishing relation between the gp120 and Gag protein of HIV, with 2019-nCoV spike glycoprotein. These proteins are  critical for  the viruses  to  identify  and  latch  on  to  their  host  cells  and  for    viral  assembly  (Beniac  et  al.,  2006). Since surface proteins are responsible for host tropism, changes in these proteins imply a change in  host  specificity  of  the  virus.  According  to  reports  from  China,  there  has  been  a  gain  of  host specificity in case 2019-nCoV as the virus was originally known to infect animals and not humans but after the mutations, it has gained tropism to humans as well.

Graphene is a wonder material, and turns out edges control whether semi or full conductors. Likewise, adding strain, by twisting ribbons, allows you to attach conducting leads.

In ASTRO-geo, it's been found that 10% off all IDP's are nano diamond, and most stony meteorites appear to have same. And in those same dust particles, they have watched graphite re-shuttle molecules across their own structure to rebuild damaged portions, that they disrupted in experiments. They think that the graphite is also converted to diamond from cosmic ray hits.

2d surfaces, and carbon in particular, are pretty amazing.

These "strange metals" clathrates, really are going to be interesting to crustal geology too. If these materials can push phonons along on the 2D surface, it could change some basic theory of seismic signals, heat transfer, and even planetary magnetism.

Seems like the "filler" materials in the "cages" could also be usefull for tracking blobs and plumes across boundries too. Signatures of volcanic emissions may be better grouped than the micro glass structures they are using now too.

who knew clathrates were going to end up being classed as "strange metals"?

Gonna be interesting how it works out....

A "diamond" cage of carbon and boron create a new type of clathrate.

"The result is a 3D, carbon-based framework with diamond-like bonding that is recoverable to ambient conditions. But unlike diamond, the strontium atoms trapped in the cages make the material metallic—meaning it conducts electricity—with potential for superconductivity at notably high temperature.

What’s more, the properties of the clathrate can change depending on the types of guest atoms within the cages.

“The trapped guest atoms interact strongly with the host cages,” Strobel remarked. “Depending on the specific guest atoms present, the clathrate can be tuned from a semiconductor to a superconductor, all while maintaining robust, diamond-like bonds. Given the large number of possible substitutions, we envision an entirely new class of carbon-based materials with highly tunable properties.”

“Our results show for the first time that such dust, at times, has cooled Earth dramatically,”

x-post from geoengineering thread.

It seems this could explain some of the hydroxyl reduction, and methane concentration spikes. If more open water, then more waves. More waves, more spray. More spray, more hydroxyl reduction from the below H2o2 reaction.

"tests confirmed that water microdroplets spontaneously form hydrogen peroxide, that smaller microdroplets produced higher concentrations of the molecule, and that hydrogen peroxide was not lost when the microdroplets recombined into bulk water.

The researchers ruled out a number of possible explanations before arriving at what they argue is the most likely explanation for hydrogen peroxide's presence. They suggest that a strong electric field near the surface of water microdroplets in air triggers hydroxyl molecules to bind into hydrogen peroxide."

a blog post by one of the authors of the above mentioned "West Antarctic ice loss influenced by internal climate variability and anthropogenic forcing"

"What Figure 1 suggests is that the winds in this region have varied between easterly and westerly from decade to decade, throughout the 20th century. This is the natural variability associated with ENSO, and is no surprise. But in addition, there is a long-term trend. When averaged over several decades, the winds can be seen to have shifted from mean easterly in the 1920s through 1980s, to mean westerly thereafter.

The trend in the winds is small, and easily lost within the variability of individual model ensemble members, but it is robust (it occurs in all the ensemble members) and statistically significant. Moreover, we know its cause (at least in the model experiments): radiative forcing. Although these experiments also include radiative forcing changes resulting from the ozone hole, it’s clear that the trend in the winds begins well before ozone depletion begins in 1970s. Thus, the key forcing is greenhouse gases."

Hadn't seen this one- reducing the number of trees in Siberia, to increase its albedo ?

"The core idea is delightfully counterintuitive: Siberia has too many trees. In ages past, Siberia used to be grassland, and today it is mostly forest. Although trees can sequester carbon in their trunks and branches (at least until they burn or decompose), Siberian forests have significant drawbacks with respect to climate change.

First, forests don’t reflect a lot of solar radiation. A treeless, grassy Siberia would increase Earth’s albedo, reflecting more solar energy back into space. Forests absorb more solar radiation and put it into the ground as heat.

Second, forests are poor habitats for snow-trampling herd animals. In the winter, a thick layer of snow acts as an insulator on the permafrost, preventing frigid above-ground temperatures from reaching deep into the Earth’s crust, where they can shore up the frozenness of the permafrost. When large herds of grazing animals trample the snow, its insulating properties are reduced and the permafrost can hard freeze. Forests reduce these snow-trampling grazing populations."

The Methane Detectives: On the Trail of a Global Warming Mystery

"Scientists continue to offer competing hypotheses to explain the global uptick, and there is no shortage of potential suspects.

Only three elements of the global methane budget are large enough to be plausible culprits: microbial emissions (from livestock, agriculture, and wetlands); fossil fuel emissions; and the chemical process by which methane is scrubbed from the atmosphere."

It could be that the RRR, the ridicoulously resilent ridge, is not outgassing as much methane right now, and that is not giving the polar streams the push out and down they have been getting the last 3-4 years.

Holocene warming effect of southern ocean

"Because of the enhanced Southern Ocean upwelling, the biological pump weakened over the Holocene, allowing more carbon dioxide to leak from the deep ocean into the atmosphere and thus possibly explaining the 20 ppm rise in atmospheric carbon dioxide.

“This process is allowing some of that deeply stored carbon dioxide to invade back to the atmosphere,” said Sigman. “We’re essentially punching holes in the membrane of the biological pump.”
