This year has seen a news frenzy like no other. Lives were disrupted throughout the world as the deadly coronavirus epidemic raged. Among these watershed moments, however, were a line of scientific breakthroughs that went unnoticed.
Inventors and engineers are drawing from these new insights and adapting nature’s answers to new technologies as scientists researching the natural world share their results. Whether scientists are trying to tackle challenges like developing better robots, detecting cancer cells more effectively, or upgrading telescopes to explore space, helpful solutions can be found in living things.
In the year 2021, several major scientific breakthroughs have occurred or are expected to occur. Here are the top ten scientific discoveries in 2021.
The viral genetic data decoding and vaccine development for the new coronavirus (SARS-CoV-2) was the most important scientific discoveries. With COVID-19’s frightening transmission rates and death tolls, researchers and medical professionals have worked tirelessly to find a solution to this global problem.
Researchers at Washington University School of Medicine are trying to figure out why COVID-19 infections cause heart damage. The current research, which is the first of its type, demonstrates how the SARS-CoV-2 virus directly infects heart muscle cells, resulting in heart failure in a subset of COVID-19 patients.
However, it was still up for discussion in the scientific community whether the damage to heart tissues was caused by direct infection to the heart or a secondary consequence of a hyperinflammatory response.
According to the senior author of the study, Kory J. Lavine, COVID is unique among viral infections since it causes a distinct immunological response in the heart.
Because cannabis is known as a Schedule 1 drug, research into its effects on the body and whether it causes COPD is limited. Furthermore, because the amounts of various cannabinoids taken vary according to the strain, joint size, how much smoke was inhaled, and how long, it may be difficult to compare any current research.
Nonetheless, some research shows that, like cigarettes, smoking cannabis is connected to COPD. This is because cannabis smoke includes many of the same compounds as cigarette smoke and, because of its temperature, irritates the airway.
As a result, studies have found that smoking cannabis over an extended length of time can cause coughing and mucus production, as well as damage mucus membranes and increase the risk of lung infections.
Researchers in the United States have created the world’s first self-healing and alive bots. Live embryonic stem cells from frogs were used to develop these xenobots. It was named after the Xenopus laevis, an African-clawed frog from which stem cells were extracted.
Xenobots might potentially be used to study human lifespan and health advances, in addition to its applications.
Cannabis use disorder (CUD) is frequent among adolescent cannabis users who suffer from mood disorders, including bipolar disorder or severe depression. However, because the link between CUD and self-harm and suicide hasn’t been well investigated, researchers at Ohio State University’s College of Medicine decided to dig further.
The study recognizes that, while there is a strong link between cannabis addiction and negative consequences, it cannot be claimed to be a direct effect and cause.
Many scientists and researchers participated in a study conducted by Fernando Colchero of the University of Southern Denmark and Susan Alberts of Duke University in North Carolina that gave fresh insights into the aging theory, known as the “invariant rate of aging hypothesis.” Every species is said to have a roughly constant rate of aging.
“Death is an unavoidable part of life. We all will eventually age and die, no matter the vitamins we take, our environment, or how much we exercise, “Fernando Colchero said. To test this hypothesis, the researchers looked at the link between life expectancy and mortality
Their findings demonstrate that when lifespan equality rises, so does life expectancy.
CRISPR-Cas 9, the most advanced genetic engineering technique, was awarded the Nobel Prize in Chemistry. Because of the versatility and ease of use of this approach, it was easy to genetically modify species that were previously difficult to do using traditional genetic engineering techniques. Humans were the first to use CRISPR-Cas9 technology to modify a gene that causes blindness.
Researchers conducted study trials in human brain cancer after successfully treating bone cancer in dogs using immunotherapy. Using immunotherapy approaches, scientists from the University of Missouri’s College of Veterinary Medicine successfully cured osteosarcoma in 14 dogs, a frequent cancer disease observed in dogs.
Scientists all around the world have been attempting to develop cultured or lab-grown meat as a replacement for farm meat. Eat Just, a US company, was able to get lab-grown meat into a Singapore restaurant. Cultured meat, according to reports, tasted identical to traditionally produced beef.
As the global demand for meat grows, this technology has the potential to remedy the problem.
A new small organ in the human body was found by chance by Dutch scientists. They discovered the tubarial glands, which are located in the upper area of the throat while investigating tumor-like growths using PSMA PET/CET.
