Most lithium-rich giant star discovered and Why Lithium important for Human?

Posted By: technopediasite


Chinese astronomers have discovered the most lithium-rich giant star ever known, which could shed new light on the evolution of the universe.

With 3,000 times more lithium than a normal star, it was found in the direction of Ophiuchus, on the north side of the galactic disk, at a distance of 4,500 light years from Earth, reports Xinhua news agency. The star has a mass almost 1.5 times our sun.

A research team, led by astronomers from National Astronomical Observatories of China (NAOC), made the discovery with the Large Sky Area Multi-Object Fibre Spectroscopic Telescope (LAMOST), a special quasi-meridian reflecting Schmidt telescope located in NAOC's Xinglong Observatory, in Hebei province.

The telescope can observe about 4,000 celestial bodies at one time and has made a massive contribution to the study of the structure of the galaxy.

Lithium is considered one of the three elements synthesised in the Big Bang, together with hydrogen and helium. The abundance of the three elements was regarded as the strongest evidence of the Big Bang.

The evolution of lithium has been a key subject in the research of the evolution of the universe and stars. However, giant stars rich in lithium are very rare, with only a few found over the past three decades. This makes their study remarkably challenging, said Zhao Gang, a lead astronomer at NAOC.

"The discovery of this star has largely increased the upper limit of observed lithium abundance," said Zhao.

I hope so many readers don’t familiar about the lithium and use of lithium. Now I would like to write in short about the lithium.

What is Lithium?
OTHER NAME(S): Atomic number 3, Carbonate de Lithium, Citrate de Lithium, Li, Lithium Carbonate, Lithium Citrate, Lithium Orotate, Litio, Numéro Atomique 3, Orotate de Lithium.

Lithium is an element. It gets its name from “lithos,” the Greek word for stone, because it is present in trace amounts in virtually all rocks. Lithium works with other elements, drugs, enzymes, hormones, vitamins, and growth factors in the body in many different ways. People use it for medicine.

Use of Lithium

Lithium is used for mental illnesses, including bipolar disorder, depression, and schizophrenia; for eating disorders, including anorexia and bulimia; and for blood disorders, including anemia and low white-cell count (neutropenia).

Lithium is also used for headache, alcoholism, epilepsy, diabetes, liver disease, kidney disorders, arthritis, a skin condition called seborrhea, and overactive thyroid. Other uses include treatment of asthma, Huntington’s disease, Graves' disease, herpes simplex, a movement disorder called tardive dyskinesia, Tourette’s syndrome, cyclical vomiting, Meniere's disease, a tingling or “crawling” sensation in the skin (paresthesias), and aggressive behavior in people with attention deficit-hyperactivity disorder (ADHD).

Side effects Of Lithium
About 75% of people who take lithium for bipolar disorder have some side effects, although they may be minor. They may become less troublesome after a few weeks as your body adjusts to the drug. Sometimes, side effects of lithium can be relieved by tweaking the dose. However, never change your dose or drug schedule on your own. Do not change the brand of lithium without checking with your doctor or pharmacist first. If you are having any problems, talk to your doctor about your options.
