A radiation sensor aboard NASA's Curiosity Mars rover is providing new data on the health risks humans would face on the surface of the Red Planet.
Unlike Earth, Mars doesn't have a magnetic field to shield it from the high-energy particles whizzing around in space. That radiation can wreak havoc on human health, and it can seriously compromise the life support systems that Mars astronauts will depend on, as well.

Based on data from Curiosity's Radiation Assessment Detector, or RAD, researchers are finding that using natural materials such as the rock and sediment on Mars could offer some protection from this ever-present space radiation.
Most of the radiation measured by RAD comes from galactic cosmic rays -- particles cast out by exploding stars and sent pinballing throughout the universe. This forms a carpet of "background radiation" that can pose health risks for humans.
Far more intense radiation sporadically comes from the Sun in the form of solar storms that throw massive arcs of ionised gas into interplanetary space.
"Cosmic rays, solar radiation, solar storms -- they are all components of space weather, and RAD is effectively a space weather outpost on the surface of Mars," said Don Hassler of the Southwest Research Institute, principal investigator of the RAD instrument, in a statement.
"The observations from RAD are key to developing the ability to predict and measure space weather, the Sun's influence on Earth and other solar system bodies," added Jim Spann, space weather lead for NASA's Heliophysics Division.
As NASA plans for eventual human journeys to Mars, RAD serves as an outpost and part of the Heliophysics System Observatory -- a fleet of 27 missions that investigates the Sun and its influence on space -- whose research supports our understanding of and exploration of space, Spann said.
RAD has measured the impact of more than a dozen solar storms to date (five while travelling to Mars in 2012), although these past nine years have marked an especially weak period of solar activity.
Scientists are just now starting to see activity pick up as the Sun comes out of its slumber and becomes more active. In fact, RAD observed evidence of the first X-class flare of the new solar cycle on October 28, 2021. X-class flares are the most intense category of solar flares, the largest of which can lead to power outages and communications blackouts on Earth.
RAD's findings will feed into a much larger body of data being compiled for future crewed missions. In fact, NASA even equipped Curiosity's counterpart, the Perseverance rover, with samples of spacesuit materials to assess how they hold up to radiation over time.

On 2nd of December, India observes 'National Pollution Control Day' in remembrance of the people who lost their lives in the 1984 Bhopal Gas Tragedy. The incident which affected over half a million people, occurred during the night of 2nd and 3rd December 1984. The leakage of gas from the Union Carbide India Limited pesticide plant in Bhopal is considered as one of the worst industrial disasters in the world. Around half a million people were exposed to the highly toxic Methyl Isocyanate gas which resulted in some losing their lives immediately, while others suffered major injuries. The cause behind the disaster is still under debate. According to the Union Carbide Corporation (UCC), it happened due to an act of sabotage.
Apart from the tragedy that happened. The day is, also, a symbol of the deteriorating state of environment. It is the need of the hour to curb and take necessary steps in order to survive. Human foot-print is turning out to be nothing but negative on the planet earth. The pollution from any human activity is not only adversely affecting the planet but no stringent measures are in place to curb the damage caused.
“Environmental pollution is a result of human activity and the development that occurs when physical, biological and chemical agents are released to the environment in such quantities that the pollution adversely affects human health and damages the environment.” The major kinds of pollution are water pollution, soil pollution, air pollution and noise pollution.
Water Pollution – Harmful chemical waste is released from factories into water bodies or rivers, which then flow and end up in seas and oceans. A lot of plastic and other waste also, end up in rivers because of littering. These affect the marine ecosystem. Fishes or other marine animals may eat and choke on them or not be able to digest them.

Soil or Land Pollution – This kind of pollution is partially linked to water pollution. When the polluted water from water bodies seep into the surrounding land, it gets polluted. Littering is a major cause of soil pollution. The chemical pesticides used in agriculture at times become pollutants.
Air Pollution – Toxic fumes and harmful gases that are emitted from factories and automobiles contribute greatly to this type of pollution. The presence of chemical constituents in high amount in the air is bad for the human body. It can cause lung cancer, heart diseases, respiratory disease and neonatal disorders.

Noise Pollution – Speakers or sound systems blaring over the decibel limit contribute to this kind of pollution. Loud noises from firecrackers are also a part of this. These affect the ability to hear, not just of humans but also other animals.
There are a lot of things that we can do to lessen the amount of pollution caused. The following are a few of them:
- Stop littering
- Use trashcans to throw away garbage
- If possible, the trash should be separated into recyclable and non-recyclable and treated accordingly
- Not waste electricity, turn off appliances and lights when not in use
- Switch to other forms of renewable energies, like the solar energy
- Use lesser amount of plastic and try to recycle whatever is absolutely necessary
- The cars should be checked on a regular basis to ensure that they do not release toxic fumes
- If possible, carpool or even better, use the public transport
- Using paper bags
- Using rechargeable batteries
Recently, a lot of brands and products are trying to be more considerate towards the environment. A particular skincare brand has started selling their products in paper tubes instead of plastic ones. Some companies are selling one-time use pens without the plastic body, the refills are instead wrapped in paper.
We have to follow the mantra of reduce, reuse and recycle in order to cut down on the amount of waste that we generate.

There is no doubt that the pandemic modified travel -- but that's just part of the story. Hilton released a global trends report, "The 2022 Traveler: Emerging Trends and the Redefined Traveler' which dives into an important truth: in two years, peoples lives were dramatically altered, and that radically changed people.
Follow NewsGram on Twitter to stay updated about the World news.
The report examines the macro trends and changes that have emerged and will continue to thrive in 2022. Using insights from Dr. Kate Cummins, a travel psychology expert, and industry leaders, the report explores four consistent themes that summarise the new, pandemic-changed traveler, which are fueling several emerging travel trends:
Amid Chaos, People Found Efficiencies, And Will Be Looking for the Same in Travel: After on-demand services, grocery deliveries, and other time-saving measures become commonplace, people expect efficiencies and convenience .Shifts like contactless payments and digital check-ins to become more popular than ever before.
The Overall Focus on Wellness Will Span Beyond the Gym: The wellness vertical has moved beyond the spa and the gym. From bringing your dog along for the trip to creating spaces with more natural light and indoor plants, mental and physical wellness is a focus that will continue to grow.

They Nurtured New and Existing Passions and Will Have More Refined Tastes and Preferences: After months of baking sourdough breads and planting victory gardens, people have new hobbies and passions, and they're expecting to pack their passions while traveling. Culinary and integrated experiences are expected to be in high demand.
Catering to this change, travellers can expect a rise in pet-friendly and sustainable travel options, unique food and beverage experiences and menu changes, and more offerings catered to guests' health and overall wellbeing -- and this is just the tip of the iceberg. The report outlines changes to guest preferences across the entire hotel experience, backed by internal booking and revenue data, guest feedback, third-party research and more. (IANS/SP)
