1. The challenging environment for science in the 21st century by Nithaya Chetty 

“Open-ended, unfettered science in its purest form has, over the centuries, been pursued in the interests of understanding nature in a fundamental way, and long may that continue. Scientific ideas and discoveries have often been very successfully exploited for commercial gain and societal improvements, and much of the science system today the world over is designed to push scientists in the direction of more relevance.”

For South Africa to prosper, Chetty encourages cooperation and innovation among scientists. He discusses several problems the country faces, including the politicization of research, a weak economy, and misuse of scientific discoveries. These challenges, he believes, can be overcome if the nation works as one and with the international community and if the education system is improved. 

2. Disadvantages of science by Ella Gray

“Technology can make people lazy. Many people are already dependent and embrace this technology. Like students playing computer games instead of going to school or study. Technology also brings us privacy issues. From cell phone signal interceptions to email hacking, people are now worried about their once private information becoming public knowledge and making profit out of video scandals.”

Gray discusses the adverse effects technology, a science product, has had on human life and society. These include pollution, the inability to communicate properly, and laziness. 

She also acknowledges that technology has made life easier for almost everyone but believes that technology, as it is used now, is detrimental; more responsible use of technology is ideal.

3. Reflections from a Nobel winner: Scientists need time to make discoveries by Donna Strickland

“We must give scientists the opportunity through funding and time to pursue curiosity-based, long-term, basic-science research. Work that does not have direct ramifications for industry or our economy is also worthy. There’s no telling what can come from supporting a curious mind trying to discover something new.”

Strickland, a Nobel Prize winner, explains that a great scientific discovery can only come with ample time for scientists to research, using her work as an example. She describes her work on chirped pulse amplification and its possible applications, including removing brain tumors. Her Nobel-awarded work was done over a long time, and scientists must be afforded ample time and funding to make breakthroughs like hers. 

4.  ​​The fact of cloning by Cesar Hill

“Any research into human cloning would eventually need to be tested on humans. Cloning might be used to create a “perfect human”. Cloning might have a detrimental effect family relationship. However the debate over cloning has more pros out weighting the cons, giving us a over site of the many advantages cloning has and the effects of it as well. Cloning has many ups and downs nevertheless there are many different ways in which it can be used to adapt and analyse new ways of medicine.”

Hill details both the pros and cons of cloning. It can be used for medical purposes and help us understand genetics more, perhaps even allowing us to prevent genetic diseases in children. However, it is expensive, and many oppose it on religious grounds. Regardless, Hill believes that the process has more advantages than disadvantages and is a net good. 

5. T. Rex Like You Haven’t Seen Him: With Feathers by Jason Farago

“For the kids who will throng this new exhibition, and who will adore this show’s colorful animations and fossilized dino poop, T. rex may still appear to be a thrilling monster. But staring in the eyes of the feather-flecked annihilators here, adults may have a more uncanny feeling of identification with the beasts at the pinnacle of the food chain. You can be a killer of unprecedented savagery, but the climate always takes the coup de grâce.”

In his essay, Farago reviews an exhibition on the Tyrannosaurus Rex involving an important scientific discovery: it was a feathered dinosaur. He details the different displays in the exhibition, including models of other dinosaurs that helped scientists realize that the T-Rex had feathers. 

6. Common, cheap ingredients can break down some ‘forever chemicals’ by Jude Coleman

“Understanding this mechanism is just one step in undoing forever chemicals, Dichtel’s team said. And more research is needed: There are other classes of PFAS that require their own solutions. This process wouldn’t work to tackle PFAS out in the environment, because it requires a concentrated amount of the chemicals. But it could one day be used in wastewater treatment plants, where the pollutants could be filtered out of the water, concentrated and then broken down.”

Coleman explains a discovery by which scientists were able to break down a perfluoroalkyl and polyfluoroalkyl substance, a “forever chemical” dangerous to the environment. He explains how they could break the chemical bond and turn the “forever chemical” into something harmless. This is important because pollution can be reduced significantly, particularly in the water.
