NASA's Insight rover has recorded two major earthquakes in the history of Mars so far  Science

Scientists hope that the results of the study of the earthquakes on Mars will help to gain a deeper understanding of the internal structure of the red planet because its waves are reflected in its layers and they are affected when they go to the measuring instruments. Insight ”spacecraft.

A team of scientists led by scientists from the University of Bristol in the UK has been able to detect two earthquakes on the surface of Mars, the most powerful ever, 5 times more than the previous record, which contributes to a better understanding. Layers of the Red Planet.

Just StudyPublished in The Seismic Record on April 22, the researchers used a seismograph on NASA’s Insight spacecraft. The surface of Mars in November 2018.

Insight, which aims to study the geological processes that have formed the solar system’s rocky planets over the past 4 million years, uses Mars as a prime model for this study, and is proud to be the first to observe Mars earthquakes in 2019.

The biggest ever

I came inside Press release The US Geological Survey, which is participating in the study, named the first earthquake “S0976a”, the strongest ever 4.2 magnitude, and occurred on August 25, 2021. The second earthquake was named “S0976A”. 1000a “(S1000a) occurred after the first 24 days and the Richter scale was 4.1.

Both earthquakes occurred in the Valles Marineris region, a group of giant valleys and valleys located along the equator of Mars.

False Mariners is one of the largest landforms in the Solar System, featuring images of Mars as it appears from space like deep cracks in the body of the planet!

Earlier studies in 2012 indicated that False Mariners were an active fault, i.e. a fault that could be the site of future earthquakes, and then S0976A and S1000A were the first evidence of the validity of this hypothesis.

According to a new study, the second earthquake, especially the “S1000A”, is a unique addition to scientific research in this area because it lasted more than 94 minutes.

In addition, the quake recorded various types of seismic waves (called Pdiff waves) through the center of the planet, and this is the first time it has been detected on the surface of Mars.

The waves of the Martian earthquakes are reflected and affected by the layers of the planet, which travel to the measuring instruments in the Insight spacecraft (foreign press).

Mars earthquake

In general, the main cause of earthquakes on Earth is the movement of tectonic plates, which periodically rub against each other, causing cracks between them, and the magnitude of this fracture. Tectonic plates are crustal layers that are 100 km to 150 km thick, moving slowly and permanently.

On Mars, there is no movement of tectonic plates, but there are other causes that lead to earthquakes on its surface, but not by the strength and magnitude of the earthquakes, i.e. cracks caused by small contractions on the planet. Cold, or the fall of a large meteorite, or rise of magma. Heat (magma) from the center of the planet and pressure on its surface from below.

Scientists hope that the results of the study of Mars earthquakes will help to achieve a deeper understanding of the internal structure of the red planet, because its waves are reflected in the layers of the planet and affected by them, they go to measuring devices. “Insight” spacecraft.

Social Unity Minister Dr. Nevin Al-Kabaj began his journey to Alexandria Governorate today, Friday, to launch the campaign.A journey of a thousand kilometersBy opening the “Reproductive Health and Early Detection of Cervical Cancer” clinic, the focus is on early detection of cervical cancer and reproductive health..

The Minister of Social Unity confirmed that the “Thousand Kilometer Journey” is scheduled to start today from Alexandria Governorate and continue for two days, from there to 9 Governorates of Beni Souf, Minya, Assiut and Sohaq. , Qana, Luxor and Aswan for two days in each governorate, and finally its activities will end in Cairo Governorate on January 5th and 6th next year..

Al-Kabbaj added that the trip targets three activities, the first of which is related to awareness, where social pioneers in those governorates will be trained to improve awareness and their medical awareness. The second part of the trip is related to training the medical staff of the clinics. In these governorates, “Reproductive Health and Early Detection of Cervical Cancer” has been prepared, where doctors and nurses will be trained on the use of various family planning methods. and the use of the cervical speculum to ensure the delivery of clinical care with high efficiency through workshops and clinical conferences..

The third part of the campaign is economic empowerment, as a bazaar will be established in each governorate where the campaign travels with the aim of promoting their products to women producers and small enterprises..

Scientists are tracking a tree in Brazil that was thought to have died out 185 years ago



Scientists are tracking a tree in Brazil that was thought to have died out 185 years ago

I retired at 100… A centenarian talks about the importance of “being busy at work” to live a long life.

Madeleine Balto recently retired at the age of 100, having worked for more than 80 years – from the age of 18 to 99. According to a CNBC report, Balto believes work has contributed to his longevity.

Balto says of his previous job: “It kept me busy, and I enjoyed the work… As for retirement, I don’t really like it.”

The Balto family started an electric sign manufacturing business in Chicago, with Madeline responsible for office work. She often interacted with customers and it was her favorite job.

She said: “I loved interacting with people… and I was the only one in the office doing all the office work, so it was fun.” “I loved going to work.”

An 85-year-old Harvard University study found that positive relationships make people happier and help them live longer. For this reason, it is not surprising that Balto places a strong emphasis on the importance of family and friends.

Assistant Professor of Medicine and Genetics and Director of Human Lifespan Studies at the Albert Einstein Institute for Aging Research, Dr. Sophia Melman says. College of Medicine.

At 100, Balto maintains his sense of community by going out to dinner with his sons and attending family events. Finally attended a wedding earlier this month.

She also likes going to the Dunkin’ Donuts branch every Sunday with her son to meet friends. “I look forward to it every week,” he says.

Balto affirms that she is lucky; Because she has some friends of the same age who often come to her house for lunch.

She added: “They always invite me over and come over for lunch on Wednesdays at 12pm… we have fun together… without your friends, where are you, right?”

While maintaining healthy relationships is an important factor in living longer, there are other factors that contributed to Balto’s longevity.

First, Mellman says, “In general, women’s life expectancy is longer than men’s…and we believe that genetics also has a significant relationship with longevity.”

In fact, Balto’s older sister lived to be 103 years old. “But she and I are the only ones who lived over 100 years,” she says, referring to her parents, who died at 84, and her sisters, who didn’t live very long.

I grew up on a vegetarian diet

Aiming to stay active, Balto says, “I’m still getting around better. I can walk up the stairs. I have energy; “so I’m in pretty good shape.”

She also tries to eat as healthy as possible, something that started in her childhood, she explains: “When I was a child, there were seven children in the family, and my father was building a big garden, so we lived mostly. On vegetables. “There wasn’t a lot of meat, we couldn’t afford meat.”

“I think that’s probably why I eat healthier,” she adds. Don’t eat fast food now.

Millman says centenarians are generally more confident, and Balto fits that description. He says it’s unclear whether centenarians are always positive, or whether they develop their positive outlook as they age.

Balto says she doesn’t feel too nervous; Because “everything can be solved.” She continues: “I’m very lucky; As I am 100 years old, I am in good health… I cannot complain about my health. “I’m walking, talking, no pain.”
