This is semantics of course, but bodies with mass are often defined as being matter.

How do herbs give medicinal properties into herbal tea/infusions?
Itoero replied to kjell159's topic in Organic Chemistry
That''s correct, you were basically on the track of making essential oil. But you need a setup and a huge number of flowers to make a little bit of essential oil. Because of active 'chemicals'. Turmeric and Green tea for example, contain phenols or polyphenols which have an antioxidant activity. The anti-oxidant activity of red wine (grape tea) comes from resveratrol. There are also herbs that have an effect on membrane ion-channels (like Bacopa monnieri and Omega 3) What's imo interesting, in a high dose/concentration certain anti-oxidants can become pro-oxidant.- 1 reply

A superconducting transition temperature (Tc) of between 260 K and 280 K was realized in a pressurized compound of lanthanum and hydrogen, they did use 2 million times the atmospheric pressure at Earth’s surface to achieve it. Although a room-temperature superconductor that requires 200 gigapascals of pressure wouldn’t be at all useful outside the lab, it could provide a road map for formulating another material that behaves similarly at ambient pressure.https://physicstoday.scitation.org/do/10.1063/PT.6.1.20180823b/full/ I'm curious to whether this has an effect on Cooper pairing.

This thread is about how religion started.https://www.scienceforums.net/topic/116094-religion-as-evolutionary-trait/ Spirituality is a broad concept with room for many perspectives. In general, it includes a sense of connection to something bigger than ourselves, and it typically involves a search for meaning in life. You might say science implies how knowledge grows via experimental evidence, while in religion people don't need experimental evidence to believe in 'things'.

The Amazon rainforest is being destroyed...
Itoero replied to laydonpher's topic in Ecology and the Environment
Can the cutting of the amazon rainforest really be stopped or decreased? People don't do it for the fun of it...it's to earn money. -
The problem with this food-blood chain exists because there are to many people. Many animal species are extinct or almost extinct because there are to many people(including the decreasing number of bees). Global warming exists basically because there are to many people. Logic dictates we will extinct ourselves…(Like the dodo in Ice age ) We have shown before that when we implement our 'smartness' into an ecosystem, we are very likely to 'mess up' the (Nature)earth further. Species (like the bee) which already are strongly decreasing in number (also because of us). It's impossible to know what 'removing' all mosquitoes will cause regarding the rest of the ecosystem so why would we extinct them? It's been shown several times before that making such changes in an ecosystem drastically changes Nature and even the Natural landscape.

Only certain species of mosquitoes of the Anopheles genus, and only females of those species, can transmit malaria. Malaria is caused y a one-celled parasite called a Plasmodium.https://en.wikipedia.org/wiki/Anopheles Malaria Vaccines are hopefulhttps://www.cell.com/cell-host-microbe/fulltext/S1931-3128(18)30320-2?_returnURL=https%3A%2F%2Flinkinghub.elsevier.com%2Fretrieve%2Fpii%2FS1931312818303202%3Fshowall%3Dtrue Many animals feed on mosquitoes: bats, birds, fish, frogs...https://www.orkin.com/other/mosquitoes/mosquito-predators/ You remove a foodsource, by extincting mosquitoes. If all mosquitoes are gone, then many animals will probably starve. It's essential to save rainforests, it's not essential to extinct mosquitoes...

I've noticed that freezing (blood and yeast) preserves the catalase, but not all of it, maybe freezing makes it less potent.

What are your opinions on the concept "Time Travel"?
Itoero replied to Department-Of-Time-Travel's topic in The Lounge
This paper is about the possibility of time travel through the geodesics of vacuum solutions.https://arxiv.org/pdf/1805.03035.pdf There is this theory that you can’t get entangled without a wormhole.http://news.mit.edu/2013/you-cant-get-entangled-without-a-wormhole-1205 A wormhole is a speculative structure linking disparate points in spacetime. Are wormholes basically timemachines? -

I don't refuse to relate to the concept of time travel...I only said what time travel can imply. -

I think it does. Time travel can imply you are travelling faster or slower in time. https://en.wikipedia.org/wiki/Time_dilation- 18 replies

What are your opinions on the concept "Time Travel"?
Itoero replied to Department-Of-Time-Travel's topic in The Lounge
No. I actually learned it on another forum and it makes a lot of sense. Several people from this forum were also on the other forum. We constantly travel trough time...you can check that on your watch. -

We constantly travel in the future else we would not 'evolve'. -
Is this in a sense due to aging of a black hole?

Yes, I'm sorry I wrongly quoted. I just learned how it works.

We might know this in a couple years: The first spacecraft to collect Martian rocks for eventual return to Earth will explore Jezero crater, NASA announced on 19 November. Jezero is a 45-kilometre-wide crater that was once filled with water, where Martian life could have thrived. “Getting samples from this unique area will revolutionize how we think about Mars and its ability to harbour life,” says Thomas Zurbuchen, NASA’s associate administrator for science, who chose Jezero over three other finalists. https://www.nature.com/articles/d41586-018-07472-0

Vaccine candidates for poor nations are going to waste. Promising immunizations for diseases that affect mostly people in low- and middle-income countries need help getting to market, urge David C. Kaslow and colleagues.https://www.nature.com/articles/d41586-018-07758-3

Two more universities in Japan have admitted to systematically favouring male applicants to their medical degrees over women. The revelations come four months after reports that Tokyo Medical University had been altering the results of its entrance examination for years to keep the proportion of female entrants below 30% of all students.The news sparked outrage in the country, and prompted a government investigation to examine whether the practice was used at other medical schools. https://www.nature.com/articles/d41586-018-07769-0

Which drug will enable us to live till 120?
Itoero replied to Obsessed With Gaming's topic in Biology
With CRISPR-cas9 and ASO-therapies you can 'in theory' make people that live longer since you can prevent (in the future) many diseases.https://en.wikipedia.org/wiki/CRISPRhttps://en.wikipedia.org/wiki/Antisense_therapy -
Are there oxygen-free zones in the Mediterranean? ( True, but according to this: https://en.wikipedia.org/wiki/Evolutionary_history_of_life there was only single-celled life before atmospheric oxygen appeared. It seems atmospheric oxygen is necessary to form complex life. Perhaps water-based photosynthesis can't form complex life due to water pressure. Or maybe complex life can be created under water, but a lot slower. Life that forms under water needs to be strong enough to deal with water pressure. The life on land could develop faster.

The occurrence of menopause evolved. The relative time at which female animals can live after their reproductive years has past differs. Two years ago, scientists suggested whales do this to focus their attention on the survival of their families rather than on birthing more offspring. But now this same team reports there’s another—and darker—reason: Older females enter menopause because their eldest daughters begin having calves, leading to fights over resources. The findings might also apply to humans, the scientists say.https://www.theguardian.com/science/2017/jan/15/killer-whales-explain-meaning-of-the-menopause Also, family groups (of killer whales)are often based on matrilines consisting of the eldest female.(matriarch).https://en.wikipedia.org/wiki/Killer_whale "As chicken farmers know, a hen’s egg production slows substantially around age four. But that’s not a sign that she’s running out of eggs. Older hens are simply more sensitive to changes in diet or light, and they stop laying when living conditions worsen. "https://slate.com/news-and-politics/2011/03/do-birds-go-through-menopause.html The reason they often say certain animal species have menopause is to make a distinction between animals that have a rather long life-span after the end of the reproductive years and animals that have a short or no life span after the end of the reproductive years. It's related to whether animals live in captivity or not.
