Fighting Drug addiction

 Here's the story: We sat down with a man who had a harrowing journey with addiction. He began by telling us about his early days in tertiary education, where he would occasionally smoke dagga with friends. However, his focus remained on his studies, and he worked hard to graduate and secure a qualification. After landing a job, he started building a life for himself. He got married, bought a property, and even splurged on a car. Life was good, and he felt like he was on top of the world. But one fateful night, while out with friends, he was introduced to heavier narcotics. At first, the experience was exhilarating. He described it as an elevation from the mild high of dagga to a level 5 high, where he felt invincible and euphoric. The effects would last for days, allowing him to party from Friday to Sunday without sleep. The problem, however, began to manifest on Mondays and Tuesdays every week, when the withdrawal symptoms would kick in, and he'd struggle to function at work....

Three entirely new lifeforms discovered on space station

 A new species never seen before by science was discovered on the space station through advanced genetic testing.

Three new lifeforms have been discovered in different locations on the International Space Station (ISS), potentially offering researchers a new way to grow food in space.

American and Indian scientists have examined four bacterial strains from the station and found that the three belonged to a species previously unknown to science.

The rod-shaped bacteria were found roughly five years ago in different locations on the station: one on the surface of a dining table, one on an overhead panel at a research station, and another in the Cupola observatory dome.

As the bacteria are proven to be able to survive the conditions of the ISS, they could contribute to humans growing food in space, according to the researchers.

University of Southern California geneticist Dr Swati Bijlani, who led the research, proposed naming the new species Methylobacterium Ajmalii in honour of Ajmal Khan, an Indian biodiversity scientist.

The discovery was published in the journal Frontiers in Microbiology and NASA believes the species offer enormous potential for growing food on missions to Mars.

The species is involved in a number of essential agricultural processes, including nitrogen fixation, phosphate solubilisation, abiotic stress tolerance, plant growth promotion, and biocontrol activity against plant pathogens.

NASA's Dr Kasthuri Venkateswaran and Dr Nitin Kumar Singh said that the strains might possess "biotechnologically useful genetic determinants" for the growing of crops in space.

However, they cautioned that further experimental biology would be required to prove that the new species of bacteria is as much of a space farming game-changer as they suspect.

"To grow plants in extreme places where resources are minimal, isolation of novel microbes that help to promote plant growth under stressful conditions is essential," they said.

"Since our group possess expertise in cultivating microorganisms from extreme niches, we have been tasked by the NASA Space Biology Program to survey the ISS for the presence and persistence of the microorganisms.

"Needless to say, the ISS is a cleanly-maintained extreme environment. Crew safety is the number one priority and hence understanding human/plant pathogens are important, but beneficial microbes like this novel Methylobacterium ajmalii are also needed."
