Reply to comment by sojayn in Aromatic hexazine rings — [N₆]⁴⁻ — an all-nitrogen analogue of benzene, have finally been synthesized by researchers using high-pressure, laser-heated synthesis. The hexazine rings are present within a complex K₉N₅₆ structure containing [N₆]⁴⁻ and [N₅]⁻ rings as well as neutral nitrogen dimers. by MurphysLab

The article states that hopefully they "can stimulate further exploration of nitrogen chemistry in the search of novel nitrogen-based technological materials."

So it looks like nothing super specific here, but it's yet another building block for the advancement of chemistry and nano technology. Now that [ N6]4- can be synthesized, it now can be studied off of paper.

Let's say we find out that cute ring is fantastic at shuttling around an ion? What if it's great at temporarily holding ions or creates a bed of electrons, similar to how precious metals work in the catalytic converter of your car. Nitrogen makes up the majority of the air we breathe, so it's dirt cheap. If it could be converted to a highly usefully ring for cheap? That'd be fantastic!

It also might be useful for synthesizing other compounds. Boron chemistry is an entire sub field because boron doesn't follow the octet rule, so it does cool things. Way beyond the scope of this response but instead of directly reacting in the reaction, it'll form intermediate complexes, or hold a temporary structure so that the reaction you want to happen can take place at all, or maybe significantly faster than without.

Edit: I'd like to add that rings, especially complex rings can be a huge pain to form. Vitamin B-12 synthesis took an obscene amount of manpower with many, many teams running concurrent studies to create parts of the vitamin, then the end goal was to link those pieces together, which took more research.

Reply to comment by Sanpaku in Oral hygiene, mouthwash usage and cardiovascular mortality during 18.8 years of follow-up - oral hygiene self-care OHS was associated with a 51% reduction in the risk of CVD mortality (hazard ratio [HR] 0.49 [0.28-0.85]; p = 0.01). by Meatrition

Mouthwash is actually not only ineffective, it is directly linked to increased blood pressure and hypertension via reducing bacteria involved in nitric oxide production which influences blood pressure.

“Conclusion: In this study, frequent regular use of over-the-counter mouthwash was associated with increased risk of hypertension, independent of major risk factors for hypertension and several other potential confounders.”

Another:

“Critically reviews evidence from a published study that suggested mouthwash use is associated with increased risk for prediabetes/diabetes.”

“those using mouthwash twice daily or more at baseline had an approximately 50% increased risk of developing prediabetes/diabetes combined, compared to those who used mouthwash less than twice daily or not at all.”

Reply to comment by PlauntieM in Pregnant women and new mothers with schizophrenia are three times more likely to visit the emergency room as a result of being victims of interpersonal violence, a new study finds. About 1 in 5 (20.7%) women with schizophrenia experience physical or sexual violence during their lifetime. by MistWeaver80

Often, other men, but domestic violence, against men, by women, is grossly underreported. Also, women attacking men is usually not only tolerated, but applauded, even when the violence is completely unjustified.

Diet affects the composition of the biome most of all. It would be funny if we discovered that linguini al fredo made us feel sexy or a big green salad made us more brainy.

Beautiful and also would you mind sharing why this is important in basic terms? I respect science enthusiasms but have no expertise

Reply to comment by WalkenTaco in Researchers in Japan have developed an inexpensive method for fabricating multi-walled carbon nanotubes (MWNTs) on a plastic film. The proposed method produces wiring suitable for developing all-carbon devices, including flexible sensors and energy conversion and storage devices. by rustoo

Yes carbon nanotubes have shown to be relatively stable in water, heat, and cold. Using carbon nanotubes instead of metal wires may also help avoid issues related to corrosion and oxidation. They also might be less prone to arcing across wires than traditional metal wires.

Reply to comment by KetosisMD in Impact of a Low-Insulin-Stimulating Bread on Weight Development—A Real Life Randomised Controlled Trial — rye bread from milled whole grain (control) or a medium-carbohydrate, low-insulin-stimulating bread (intervention). Significant weight reduction was observed in the intervention group. by Meatrition

There's a lot of fiber in that bread. I wonder if the people who lost weight simply didn't absorb the same amount of calories as the people who were eating normal bread, because normal bread is easier to digest.

Reply to comment by Atomic_Wrangler2 in Consumers respond less positively to new products when their brand names use unconventional spellings of real words, like “Klear” instead of “Clear.” Findings showed that consumers saw these names as indicating the brand was less honest, down-to-earth and wholesome. by geoff199

Food has been considered medicinal for at least 2000 years. Dietitians exist for this purpose, to treat conditions through food based therapy in a clinical setting.

But is it really always meat from baby sheep? In my native language we call it 'sheep meat'.

I've also visited a farm where they slaughtered their own sheep and that was an animal that was a couple of years old. I must admit that I found the taste of that meat pretty strong and not so pleasant but I'm generally not really into lamb anyway.

If one invents something. Like Velcro or the internet, you get to name it. Labeling some food a “nutraceutical” is just an attempt to grift buyers into seeing it as medicine.. which it isn’t.

Would this be inherently more stable across multiple environments? Like waterproof/cold & heat resistant, etc? Seems like a circuit being all carbon would remove some of the issues with getting copper wet as well as arcing across wires if the carbon separating the "wires" has a high resistance compared to the "wires"
