The Science Behind Relationships; Humans Media explores the basis of our attraction, contempt, why we do what we do and to whom we do it.
The effects of mobile phones on skeletal structure
Envision a scenario in which cellphones possessed the astonishing capacity to influence the actual construction of our bones. This captivating and recently emerged topic has been causing ripples across various media platforms, originating from a scientific report suggesting that the use of phones and tablets can lead to substantial and enduring changes in our bodies. As opposed to customary assumptions, a review led by biomechanics experts David Shahar and Imprint Sayers at Australia's College of the Daylight Coast uncovers an expected connection between present day innovation and modifications in the skeletal construction of youthful people.

Decode Life: A Fast-Track Guide to DNA Structure & Replication - Crash Course Biology
DNA serves as the ultimate blueprint for creating and maintaining the human body. It holds all the necessary information for the functioning of every living organism. Within each organism are trillions of cells, each requiring its own copy of this extensive manual. Printing out the 3 billion letters of genetic code within DNA would result in hundreds of thousands of pages. The recent completion of sequencing the human genome in 2022 marks a significant milestone in scientific history. This breakthrough could lead to a better understanding of various aspects, such as human similarities and differences with other species, individual responses to medications, and more effective treatments for diseases like cancer. Let's delve into the composition of DNA, made up of nucleotides containing a sugar molecule, a phosphate group, and one of four nitrogen-containing bases. These nucleotides combine to form the iconic double helix structure of DNA, resembling a twisted ladder. The sugar-phosphate backbones and nucleotide bases play crucial roles in DNA's structure and function. The pairing of adenine with thymine and guanine with cytosine, connected by hydrogen bonds, is essential in maintaining a healthy DNA strand. These four bases, A, T, C, and G, make up the genetic code's alphabet, determining individual characteristics and traits. The specific sequence of these bases in DNA distinguishes one organism from another. The genetic information stored in DNA is organized into chromosomes, coiled around proteins within the cell nucleus. Virtually every cell in the human body contains a complete set of chromosomes with the genetic blueprint encoded in DNA.

MORE THAN A MOVEMENT
Introduction: International Women's Day stands as a global celebration of the achievements and progress made by women throughout history. Yet, beyond the flowers, gifts, and well-wishes, this day symbolizes a profound call to action—a reminder of the ongoing journey towards gender equality. In the midst of this celebration, it is crucial to delve into the complexities of this movement, understanding the nuances of perplexity and burstiness within the narratives of women's rights and empowerment.

A 'jumping' gene caused humans to lose their tails
Introduction: The evolution of humans and their distinctive traits has long fascinated scientists, with one of the most intriguing mysteries being the loss of the tail. While our primate ancestors boasted this appendage, humans today only briefly exhibit it during gestation. Recent research, published in the journal Nature, sheds light on this enigma, pointing to a genetic mechanism responsible for the disappearance of the tail during human evolution.In the mind boggling embroidery of human development lies an entrancing story of hereditary portability and transformation. Implanted inside our hereditary code are leftovers of a far off past, murmurs of when our progenitors strolled an alternate way. Among these hereditary relics, one especially captivating component sticks out: the bouncing quality.

The Tongue Is the Strongest Muscle in the Body
It can bend, it can twist, it can suck, it can cup. The tongue is an essential, often playful part of human anatomy. Many of us grew up believing the assertion that the tongue is the strongest muscle in the body. But is it really? The short answer is no. But the explanation is not as straightforward as you’d think. We asked a few tongue experts (yes they do exist) why the myth has been so easy to swallow. Maureen Stone, of the University of Maryland School of Dentistry, speculates that the myth of the tongue’s strength arose from its amazing stamina even in precision tasks like eating and speaking. “When’s the last time your tongue was tired?” she asks. “If you don’t have any disorders, the answer is probably never.” Stone says the tongue’s tenacity springs from the way it is built—with lots of similar bits of muscle that can each perform the same task. “It doesn’t fatigue,” she says, “because there’s a lot of redundancy in the muscle architecture. You simply activate different muscle fibers and get the same result.” Stephen Tasko, a speech scientist at Western Michigan University, says that the question of whether the tongue is the strongest muscle in the body is itself misinformed. The soft patty of flesh we call the tongue is not just one muscle, it’s a conglomeration of eight separate muscles. Unlike other muscles, such as the bicep, tongue muscles don’t develop around a supporting bone. Rather, they intertwine to create a flexible matrix, forming what is called a muscular hydrostat; this structure is similar to an octopus’s tentacles or an elephant’s trunk. Four muscles in the matrix, called the extrinsic muscles, anchor the tongue to structures in the head and neck. One muscle holds on to the base of the skull, another connects to a bone in the throat, there is a muscle that grabs on to the lower jaw and another wrapped around the palate. These propel the tongue from side to side, front to back and up and down. The rest of the muscles make up the tongue’s body. They’re what give it the ability to contort into endless arrays of shapes and postures. They allow it to lengthen, shorten, curl, flatten and round, and they provide shape to assist in speaking, eating and swallowing.

A Note on Toxic Femininity
When it comes to the subject of gender, the subject of toxic masculinity and its detrimental effects on individuals in society is rightfully given a lot of attention. However, it is equally important to shed light on another aspect of gender dynamics, inequality, and equality: toxic femininity. Toxic femininity refers to the adherence to harmful gender norms and stereotypes that enable and continue the subjugation, oppression, discrimination, and inequality of women, often at the expense of their well-being and the well-being of others in society.
