Fresh insight on how diamonds are formed

Washington: New findings have revealed long unknown details about how carbon deep beneath the Earth’s surface is helping diamond formation in the Earth’s mantle.

The new theoretical model called the “Deep Earth Water” model allowed researchers to determine the chemical makeup of fluids in the Earth’s mantle, expelled from descending tectonic plates.

“These mantle fluids with dissolved organic carbon species could be creating diamonds in a previously unknown way,” the authors said.

The Johns Hopkins University-led team in the US found that some of the fluids at 100 miles below the Earth’s surface contained the expected carbon dioxide and methane.

But others, those in equilibrium with diamonds, contained dissolved organic carbon species including a vinegar-like acetic acid.

“These high concentrations of dissolved carbon species, previously unknown at great depths in the Earth, suggest they are helping to ferry large amounts of carbon from into the overlying mantle wedge where they are likely to alter the mantle and affect the cycling of elements back into the Earth’s atmosphere,” said Dimitri Sverjensky, geochemist and professor in the department of earth and planetary sciences.

Scientists have long believed diamond formation resulted through chemical reactions starting with either carbon dioxide or methane.

Sverjensky and his team also demonstrated that in addition to the carbon dioxide and methane, there exists a rich variety of organic carbon species that could spark microbial life.

“It is a very exciting possibility that deep fluids beneath the Earth’s surface might transport building blocks for life into the shallow Earth. This may be a key to the origin of life itself,” Sverjensky said.

The article was published in the journal Nature Geoscience.

ily foods, spicy dishes, fried fares… Done it all and regretting it? If you’re suffering from acid reflux, you probably know what to eat and what to avoid. But is there anything to relieve you from such digestive issues? Well, there are certain drinks for acidity to improve your digestive health, if you consume them regularly.

Ready to find out? Let’s go!

In an Instagram video, nutritionist and health coach Neha Ranglani has suggested that to calm your acid reflux, you need to help your food get digested well. This can be done by improving your stomach acid production and healing your stomach cells. And these drinks that she has suggested, can help with just that, allowing you to digest your food well without the burn.

Here are 6 drinks for acidity:

1. Cucumber juice

Cucumber is a favourite salad ingredient in summer because of its cooling properties. Consuming cucumber juice can be really beneficial for relievingacid reflux because it is highly nutritious as it provides your body with both fibre and water which is needed for better digestion and has a low calorie volume. What’s more? It can also keep you full and help you avoid reaching out to junk foods!

2. Lemon water

Lemon can do you a world of good! Being rich in vitamin C and B and minerals such as phosphorus, calcium, and magnesium—drinking lemon water regularly will not only help you burn fat but will resolve your digestive issues such as acidity. Moreover, lemon water contains laxative properties that can help improve your bowel movements and clear toxins from the body, keeping you hydrated.

3. Ginger water

Ginger aka adrak, is a very well known ingredient that has been used for ages to help relieve acidity and gas. Also, if you are facing digestive issues due to overeating or undigested food, consuming ginger water can help in emptying your stomach. You can also consume it by adding it to soups, subzi or curry, and even tea. Remember that you’re not allowed to consume ginger in excess amounts.
