NASA Probe ‘InSight’ Detects Likely ‘Marsquake’- Marking First Seismological Tremor Recorded on Another Planet
NASA’s robotic probe InSight has detected and measured what scientists believe to be a “marsquake,” marking the first time a likely seismological tremor has been recorded on another planet, the Jet Propulsion Laboratory in California reported on Tuesday.
The breakthrough came nearly five months after InSight, the first spacecraft designed specifically to study the deep interior of a distant world, touched down on the surface of Mars to begin its two-year seismological mission on the red planet.
The faint rumble characterized by JPL scientists as a likely marsquake, roughly equal to a 2.5 magnitude earthquake, was recorded on April 6 – the lander’s 128th Martian day, or sol. It was detected by InSight’s French-built seismometer, an instrument sensitive enough to measure a seismic wave just one-half the radius of a hydrogen atom.
“We’ve been collecting background noise up until now, but this first event officially kicks off a new field: Martian seismology,” InSight principal investigator Bruce Banerdt said in a news release.
Scientists are still examining the data to conclusively determine the precise cause of the signal, but the trembling appeared to have originated from inside the planet, as opposed to being caused by forces above the surface, such as wind.
“The high frequency level and broad band is very similar to what we get from a rupture process. So we are very confident that this is a marsquake,” Philippe Lognonné, a geophysics and planetary science professor at University Paris Diderot in France and lead researcher for InSight’s seismometer, said in an email.
Still, a tremor so faint in Southern California would be virtually lost among the dozens of small seismic crackles that occur there every day.
“Our informed guesswork is that this a very small event that’s relatively close, maybe from 50 to 100 kilometers away” from the lander, Banerdt told Reuters by telephone.
A more distant quake would yield greater information about Mars’ interior because seismic waves would “penetrate deeper into the planet before they come back up to the seismometer,” he said.
No Tectonic Plates
The size and duration of the marsquake also fit the profile of some of the thousands of moonquakes detected on the lunar surface between 1969 and 1977 by seismometers installed there by NASA’s Apollo missions, said Lori Glaze, planetary science division director at NASA headquarters in Washington.
The lunar and Martian surfaces are extremely quiet compared with Earth, which experiences constant low-level seismic noise from oceans and weather as well as quakes that occur along subterranean fault lines created by shifting tectonic plates in the planet’s crust.
Mars and the moon lack tectonic plates. Their seismic activity is instead driven by a cooling and contracting process that causes stress to build up and become strong enough to rupture the crust.
Three other apparent seismic signals were picked up by InSight on March 14, April 10 and April 11 but were even smaller and more ambiguous in origin, leaving scientists less certain
they were actual marsquakes. Lognonné said he expected InSight to eventually detect quakes 50 to 100 times larger than the April 6 tremor. (VOA)
South Korean game developer has introduced a new initiative for Battlegrounds Mobile India (BGMI) which will enable a new level of parental control via time limitations and OTP confirmation. The 'Game Responsibly' initiative will also show warning messages along with break reminders, game limits and more. "Every player, below the age of 18, needs to register a parent or a guardian before they start playing for the first time. An OTP will be sent to the registered person's number, post which the minor is allowed to play the game," the company said in a statement.
Some games can get intense and make players lose track of time. However, with timely break-time reminders, the developer has made sure players get the required downtime. These reminders will help them look up from their game and get back to real life, maintaining a healthy game-life balance. In addition, with a strict gameplay limit in place players below 18 years must not indulge in gaming for more than 3 hours per day. This automatically helps them treat gaming as an activity performed in moderation.
The brand has also set an in-game daily spend limit of Rs 7,000 that automatically stops them from overspending and overgaming. Krafton recently announced that it has removed 25 lakh accounts in just over a month to eradicate cheating on Battlegrounds Mobile India (BGMI). Since the last announcement, between October 1 and November 10, Krafton banned 25,19,692 accounts permanently and 7,06,319 temporarily. "The company has cleaned out most of the cheaters in the game, making BGMI a much more fun experience, and will continue to take whatever step is necessary to keep BGMI fair and fun," it claimed.

The rise in air pollution, coupled with lousy lifestyle habits, is causing a spike in respiratory diseases. According to a Lancet report, the contribution of chronic respiratory diseases in India increased from 4.5 per cent in 1990 to 6.4 per cent in 2016. With respiratory issues on the rise, there is an increased demand for natural solutions to treat such issues. Instead of conventional medicine, people are turning to alternative medical therapies to find cures for ailments.
Common Lung Disorders
Bronchitis is a health condition that causes inflammation in the airways of the lungs. This leads to narrowing of the air pathways and excess mucus causes wheezing, coughing and difficulty breathing. It is a chronic condition that interferes seriously with daily life.

Chronic Obstructive Pulmonary Disease (COPD)
It is a chronic inflammatory lung disease that obstructs the airflow to the lungs. Symptoms of COPD include breathing difficulty, mucus (sputum) production, coughing, and wheezing. It can result from long-term exposure to irritating gases or particulate matter, most often from cigarette smoke. Those affected by COPD are at an increased risk of developing lung cancer, heart disease, and a variety of other conditions.

This is another variation of COPD. Bronchitis causes a similar build-up of mucus that can cause inflammation and coughing. The lungs' airways are constantly inflamed as chronic bronchitis often lasts for months on end. Symptoms of chronic bronchitis include incessant coughing, whistling sounds while breathing, wheezing and a tightening of the chest. It is said that the cure for all ailments is available the natural way. Here are some of the alternative medicine approaches to treat respiratory disorders.

Alternative Medicinal Approaches to Treat Respiratory Disorders
Asthma is one of the most common lung diseases. One of the primary causes of asthma is allergies, which often result from the food consumed. It is crucial, therefore, to first prepare a diet that is suitable for an individual. Often, dairy products, meats, and certain nuts can increase the production of mucus. Foods like these must be avoided. Also, antioxidants can prevent damage resulting from chronic obstructive pulmonary disease. Diet is important in this regard, as fruits and vegetables high in Vitamins A, C, and E can improve the condition of COPD patients.

Yoga and Exercise
Treatment of lung disorders often involves the use of the lungs to promote healthy breathing habits. Exercises like cycling, swimming, yoga etc. that create a need for full capacity breathing are of great importance. Exercising the diaphragm is important and simple activities can go a long way in the treatment of the same. Pranayama, the practice of controlled breathing, is an integral part of alternative treatment for people suffering from respiratory issues. This extensive breathing practice helps to expand the lungs and improve the capacity of the lungs, which helps an individual breathe more freely.

The traditional Chinese practice of acupuncture involves inserting thin needles into the skin to stimulate certain parts of the body. According to a study published in the journal Annals of Allergy, Asthma and Immunology, people with allergic rhinitis who were given acupuncture treatments twice a week for eight weeks had fewer symptoms than those administered placebo.

It is important to remember that no one complementary or alternative therapy works well for everyone with respiratory issues. Therefore, a proper assessment is done before deciding on the approach to the treatment plan. For those considering alternative medicine for their respiratory problems, it is recommended to speak to an expert first and discuss the approach that may work best.

Did you know that over 40-year-olds might lose up to 8 per cent of their muscular mass every decade? After the age of 70, the pace of decrease may double. Sarcopenia, or advanced muscle loss, affects roughly one-third of persons over the age of 50. Muscles are crucial for organ function, skin health, immunity and metabolism, as well as for common physical acts like picking things up, reaching for something, opening a jar or getting out of a chair. To put it another way, keeping muscle mass as you become older is critical to living a happy and healthy life. "Muscle loss is an ageing factor that is rarely discussed, and people accept its signs, such as a loss of strength and energy, as a natural part of ageing," says Ganesh Kadhe, Associate Director Medical and Scientific Affairs at Abbott Nutrition. "However, muscle fitness can often predict how we will age and remain active and independent."

The good news is that you may assist, prevent or delay muscle loss by taking the appropriate precautions. While muscle loss is unavoidable as we age, it does not have to be.
To stay strong as you age, start following the tips below to fuel and keep muscles fit for years to come!
1. Engage in regular exercise, including resistance training, to maintain muscles and strength.
2. Eat good source of protein from lean meats, eggs and beans; aim for 25-30 grams of protein at every meal.
3. Choose a balanced diet full of veggies, fruits, whole grains, proteins, healthy fats and key vitamins and minerals like calcium and vitamin D.
4. Consider taking other muscle health ingredients, like HMB.
5. Talk to your healthcare provider about nutrition, especially if you are ill, hospitalised or recovering from surgery, to manage illness-related muscle loss.
