Astronomical Institute: “Leonard” bright comet in 2021, close to Earth tomorrow

معهد الفلك: "ليونارد" ألمع مذنب بـ2021 الأقرب إلى الأرض غدا

Will pass Comet Leonard Tomorrow, Sunday, December 12, about 34 million km from Earth, and then six days later – on December 18 – the comet will be exceptionally close to Venus and 4.2 million km from it.

The National Agency for Astronomical Research has revealed that the comet C / 2021 A1 (Leonard) will be the brightest comet in 2021 and will be closest to Earth on December 12.

The comet now appears brighter, so it can be seen with a telescope, and the comet’s brightness will be visible to the naked eye (from very dark places) for the next few days, and the comet was discovered by astronomers on January 3, 2021. George Leonard of the Mount Lemon Observatory in Arizona, USA.

The comet orbits the Sun at about 254,412 km / h or 70.67 km / second. It will reach its closest distance (perihelion) on January 3, 2022 at a distance of about 90 million km.

Comets are usually much brighter around the perihelion.

Orbital calculations show that the comet orbited the Sun for the past 35,000 years after reaching the abeline (the farthest distance from the Sun) at a distance of about 3,500 astronomical units (3,500 times the distance between the Earth). And the sun) to complete tens of thousands of years around the sun

And the astronauts continued: That is, the comet Leonard may be one of the only celestial bodies to be seen only once in a lifetime.

Are nuts better for breakfast than eggs?  Scientists have the answer

“Stem cells” show “promising results” in treatment of “multiple sclerosis”.

A recent study shows that injecting a type of stem cells into the brains of patients with multiple sclerosis achieves promising results and can protect the brain from damage from the disease.

The study, published Monday in the journal Stem Cell by researchers from Britain and Italy, is a step toward developing an advanced stem cell therapy for multiple sclerosis, a crippling disease that leaves some sufferers unable to walk on their own. walk in general.

More than two million people worldwide live with multiple sclerosis, which is caused by the body’s immune system destroying “myelin,” the protective sheath around the nerve fibers surrounding the brain and spinal cord. brain and other parts of the body.

Recent research advances have revealed that stem cell therapies can help reduce this vulnerability by infusing or transplanting “master” stem cells into the body.

After a previous successful study conducted in mice to test this approach, the researchers continued their new study in humans, where neural stem cells were injected directly into the brains of 15 multiple sclerosis patients in Italy.

Stem cells were extracted from cells taken from fetal brain tissue, and the researchers followed the patients for 12 months, during which time there were no treatment-related deaths or serious adverse effects.

At the start of the trial, all patients showed a high degree of disability, with most requiring a wheelchair.

However, during the 12-month follow-up period, none of them showed an increase in disability or worsening of symptoms, and none of the patients reported symptoms suggestive of relapse, and their cognitive functions did not deteriorate significantly during the study period. Researchers believe this indicates significant persistence of the disease.

The researchers evaluated a subset of patients for changes in the volume of brain tissue associated with disease progression, and found that the higher the dose of injected stem cells, the smaller the brain volume over time.

Professor Stefano Pluchino, the lead researcher of the study from the University of Cambridge in the UK, says: “This study is the first phase of clinical trials in humans to assess the feasibility, safety and tolerability of neural stem cell injections in patients with multiple sclerosis.”

He added to Asharq Al-Awsat, “The success achieved by the group at this stage is a prerequisite for developing efficacy studies, which will be the next step for the research group,” pointing out that “experiments will be conducted in larger numbers. Patients should better monitor the therapeutic effects of this approach.”

Turmeric…what are its benefits and who should avoid using it?

Dubai, United Arab Emirates (CNN) — Turmeric is considered one of the most important spices in Indian and Pakistani cuisine, and is an essential ingredient in the world-famous “curry” dish. But it also has many therapeutic properties due to the presence of a chemical compound called curcumin.

What do you know about him?

Historically, turmeric has been used in traditional Chinese and Indian medicine, according to the official US website “GovInfo”.

This, in turn, helps digestion and liver function, relieves joint pain, and regulates menstruation. It is applied directly to the skin to treat eczema and heal wounds.

Today, turmeric is used for heartburn, stomach ulcers and gallstones.

Add turmeric as a spice to salty and sweet foods, or drink it as a tea, mixed with honey and lemon juice and sipped with castor oil to flush out toxins from the skin.

Southwest India is considered the original home of turmeric, but it is widespread in India and Indonesia, and is internationally known as “Curcuma longa”.

Here are some benefits of turmeric:

  • It is useful in treating wounds and inflammation. It increases liver function to secrete bile, stimulates bowel movements and helps dissolve the gallbladder.
  • Turmeric is a natural antiseptic and antibacterial, and is useful in disinfecting wounds and burns.
  • Turmeric can prevent melanoma, kill skin cancer cells and reduce the risk of childhood leukemia.
  • Turmeric prevents the development of Alzheimer’s disease by removing amyloid deposits in the brain.
  • It has long been used in Chinese medicine as a treatment for depression.

However, the United States’ official website “GovInfo” warned about one thing: people with gallbladder diseases should avoid using turmeric as a nutritional supplement, especially if it worsens their health.
