The Martian subsurface might be a good place to look for possible present-day life on the Red Planet, according to a study. The study, published in the journal Astrobiology, looked at the chemical composition of Martian meteorites — rocks blasted off of the surface of Mars that eventually landed on Earth.
The analysis determined that those rocks if in consistent contact with water, would produce the chemical energy needed to support microbial communities similar to those that survive in the unlit depths of the Earth. Because these meteorites may be representative of vast swaths of the Martian crust, the findings suggest that much of the Mars subsurface could be habitable.

“The big implication here for subsurface exploration science is that wherever you have groundwater on Mars, there’s a good chance that you have enough chemical energy to support subsurface microbial life,” said Jesse Tarnas, a postdoctoral researcher at NASA’s Jet Propulsion Laboratory. “We don’t know whether life ever got started beneath the surface of Mars, but if it did, we think there would be ample energy there to sustain it right up to today,” Tarnas added.
For the study, the researchers wanted to see if the ingredients for radiolysis-driven habitats could exist on Mars. They drew on data from NASA’s Curiosity rover and other orbiting spacecraft, as well as compositional data from a suite of Martian meteorites, which are representative of different parts of the planet’s crust.
The study found that in several different types of Martian meteorites, all the ingredients are present in adequate abundance to support Earth-like habitats. Unlike Earth, Mars lacks a plate tectonics system that constantly recycles crustal rocks. So these ancient terrains remain largely undisturbed, the researchers noted. “The subsurface is one of the frontiers in Mars exploration,” said Jack Mustard, Professor at Brown University.
“We’ve investigated the atmosphere, mapped the surface with different wavelengths of light, and landed on the surface in half-a-dozen places, and that work continues to tell us so much about the planet’s past. But if we want to think about the possibility of present-day life, the subsurface is absolutely going to be where the action is,” Mustard said. (IANS/SP)

The prestigious British-based, Booker Prize, is one of the most prestigious and acclaimed awards given annually to the best work of fiction. This award is given to a work of fiction which is primarily written in English language and published in the United Kingdom or Ireland by the writers of any nationality.
This year, six authors were nominated for their work of fiction, and the winner will be announced on the 3rd of November.
The books which were shortlisted for the prestigious Booker Prize 2021 are:
1. The Fortune Men by Nadifa Mohamed
British-Somali writer, Nadifa Mohamed's novel, 'The Fortune Men', is a chilling reimagining of Mahmood Mattan's story. Mattan, who is the main character in the book, was a Somali seaman who was wrongfully imprisoned and executed for a murder in Wales.
2. Bewilderment by Richard Powers
Pulitzer-winner, Richard Powers' book is a story of a young astrobiologist, who is in search of finding life on other planets, and his troubled son, Robin. The book is a mixture of sci-fi and family romance. Interestingly, this is Powers' first book after winning the Pulitzer Prize in the year 2019.
3. Great Circle by Maggie Shipstead
This book is about the lives of pilot Marian Graves and Hadley Baxter, who was a troubled Hollywood actress. In the 1950s, Marian embarked on a journey to travel the world but then disappeared without a trace. Fifty years later, Hadley is drawn to play Marian's character, which indirectly leads her to probe the mysteries of the latter's life.
4. No One is Talking About This by Patricia Lockdwood
This is the first book by the American poet and memoirist. " 'No One Is Talking About This' is like a love letter to the endless scroll and a profound, modern meditation on love, language, and human connection from a singular voice in American literature," reads the book's blurb. This book was also one of the finalists for this year's Women's Prize for Fiction.
5. A Passage North by Anuk Arudpragasam
The Sri Lankan author's book tells the story of a young man who travels to Sri Lanka's war-torn North. The story deals with the themes of loss, longing, the legacy of war, and how it affects everyone. The author had earlier won the DSC Prize for his debut book "The Story of a Brief Marriage".
6. The Promise by Damon Galgut
Damon Galgut is a South African author. In this book, the author pens down the story about a white South African family living around in Pretoria, and the crisis they face during the last few years because of apartheid.
Today, 17 September,marks the 133rd birth anniversary of Michiyo Tsujimura, who was a Japanese scientist, and worked extensively on decoding the nutritional value of green tea.
Tsujimura spent her early career as a science teacher. And, in 1920, she chased her dream of becoming a scientific researcher at the Hokkaido Imperial University, where she began to analyse the nutritional properties of Japanese silkworms, in which she was very much interested.
After a few years, Tsujimura transferred to the Tokyo Imperial University, and began researching the biochemistry of green tea alongside Dr. Umetaro Suzuki, who is well known for his discovery of vitamin B1.
In their joint research in this area, it was revealed that green tea contained significant amount of vitamin C, which is the first of many, yet unknown molecular compounds in green tea.
Later on, in 1929, Tsujimura isolated catechin, which is bitter ingredient of tea. Then, the next year, she isolated tannin, which is an even more bitter compound. All these findings formed the foundation for her doctoral thesis– "On the Chemical Components of Green Tea", and through all this hard work, she graduated as Japan's first woman doctor of agriculture in the year 1932.
Moreover, Tsujimura also made history as an educator when she became the first ever Dean of the Faculty of Home Economics at the Tokyo Women's Higher Normal School in the year 1950.
Even today, a stone memorial in honor of Dr. Michiyo Tsujimura’s achievements can be found in her birthplace of Okegawa City.
