Human Enhancement
Human enhancement is the natural, artificial, or technological alteration of the human body in order to enhance physical or mental capabilities. Technologies Existing technologies Three forms of human enhancement currently exist: reproductive, physical, and mental. Reproductive enhancements include embryo selection by preimplantation genetic diagnosis, cytoplasmictransfer, and in vitro-generated gametes. Physical enhancements include cosmetics ( plastic surgery and orthodontics), Drug-induced (doping and performance-enhancing drugs), functional (prosthetics and powered exoskeletons), Medical ( implants (e.g. pacemaker) and organ replacements (e.g. bionic lenses)), and strength training (weights (e.g. barbells) and dietary supplement)). Examples of mental enhancements are nootropics, neurostimulation, and supplements that improve mental functions. Computers, mobile phones, and Internet can also be used to enhance cognitive efficiency. Notable efforts in human augmentation are ...

Technology
Technology is the application of Conceptual model, conceptual knowledge to achieve practical goals, especially in a reproducible way. The word ''technology'' can also mean the products resulting from such efforts, including both tangible tools such as Kitchen utensil, utensils or machines, and intangible ones such as software. Technology plays a critical role in science, engineering, and everyday life. Technological advancements have led to significant changes in society. The earliest known technology is the stone tool, used during prehistory, followed by the control of fire—which in turn contributed to the Brain size, growth of the human brain and the development of language during the Pleistocene, Ice Age, according to the cooking hypothesis. The invention of the wheel in the Bronze Age allowed greater travel and the creation of more complex machines. More recent technological inventions, including the printing press, telephone, and the Internet, have lowered barriers to ...

Gender-affirming Surgery
Gender-affirming surgery (GAS) is a surgical procedure, or series of procedures, that alters a person's physical appearance and sexual characteristics to resemble those associated with their gender identity. The phrase is most often associated with transgender health care, though many such treatments are also pursued by cisgender individuals. It is also known as sex reassignment surgery (SRS), gender confirmation surgery (GCS), and several #Terminology, other names. Professional medical organizations have established Standards of Care for the Health of Transgender and Gender Diverse People, Standards of Care, which apply before someone can apply for and receive reassignment surgery, including psychological evaluation, and a period of real-life experience living in the desired gender. Gender-affirming surgery (male-to-female), Feminization surgeries are surgeries that result in female-looking anatomy, such as vaginoplasty, vulvoplasty and breast augmentation. Gender-affirming ...

Human-animal Chimera
A human chimera is a human with a subset of cells with a distinct genotype than other cells, that is, having genetic chimerism. In contrast, an individual where each cell contains genetic material from a human and an animal is called a ''human–animal hybrid'', while an organism that contains a mixture of human and non-human cells would be a ''human-animal chimera''. Mechanisms Some consider mosaicism to be a form of chimerism, while others consider them to be distinct. Mosaicism involves a mutation of the genetic material in a cell, giving rise to a subset of cells that are different from the rest. Natural chimerism is the fusion of more than one fertilized zygote in the early stages of prenatal development. It is much rarer than mosaicism. In artificial chimerism, an individual has one cell lineage that was inherited genetically at the time of the formation of the human embryo and the other that was introduced through a procedure, including organ transplantation or blood tra ...

Human-animal Hybrid
Anthrozoology, also known as human–animal studies (HAS), is the subset of ethnobiology that deals with interactions between humans and other animals. It is an interdisciplinary field that overlaps with other disciplines including anthropology, ethnology, medicine, psychology, social work, veterinary medicine, and zoology. A major focus of anthrozoologic research is the quantifying of the positive effects of human–animal relationships on either party and the study of their interactions. It includes scholars from fields such as anthropology, sociology, biology, history and philosophy. Anthrozoology scholars, such as Pauleen Bennett, recognize the lack of scholarly attention given to non-human animals in the past, and to the relationships between human and non-human animals, especially in the light of the magnitude of animal representations, symbols, stories and their actual physical presence in human societies. Rather than a unified approach, the field currently consists o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
3D Bioprinting
Three dimensional (3D) bioprinting is the use of 3D printing–like techniques to combine cells, growth factors, bio-inks, and biomaterials to fabricate functional structures that were traditionally used for tissue engineering applications but in recent times have seen increased interest in other applications such as biosensing, and environmental remediation. Generally, 3D bioprinting uses a layer-by-layer method to deposit materials known as bio-inks to create tissue-like structures that are later used in various medical and tissue engineering fields. 3D bioprinting covers a broad range of bioprinting techniques and biomaterials. Currently, bioprinting can be used to print tissue and organ models to help research drugs and potential treatments. Nonetheless, translation of bioprinted living cellular constructs into clinical application is met with several issues due to the complexity and cell number necessary to create functional organs. However, innovations span from bioprint ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Nanomedicine
Nanomedicine is the medical application of nanotechnology, translating historic nanoscience insights and inventions into practical application. Nanomedicine ranges from the medical applications of nanomaterials and biological devices, to nanoelectronic biosensors, and even possible future applications of molecular nanotechnology such as biological machines. Current problems for nanomedicine involve understanding the issues related to toxicity and environmental impact of nanoscale materials (materials whose structure is on the scale of nanometers, i.e. billionths of a meter). Functionalities can be added to nanomaterials by interfacing them with biological molecules or structures. The size of nanomaterials is similar to that of most biological molecules and structures; therefore, nanomaterials can be useful for both in vivo and in vitro biomedical research and applications. Thus far, the integration of nanomaterials with biology has led to the development of diagnostic d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Strategies For Engineered Negligible Senescence
Strategies for engineered negligible senescence (SENS) is a range of proposed regenerative medical therapies, either planned or currently in development, for the periodic repair of all age-related damage to human tissue. These therapies have the ultimate aim of maintaining a state of negligible senescence in patients and postponing age-associated disease.de Grey, Aubrey; Rae, Michael (September 2007). ''Ending Aging: The Rejuvenation Breakthroughs that Could Reverse Human Aging in Our Lifetime''. New York, NY: St. Martin's Press, 416 pp. . SENS was first defined by British biogerontologist Aubrey de Grey. Many mainstream scientists believe that it is a fringe theory. De Grey later highlighted similarities and differences of SENS to subsequent categorization systems of the biology of aging, such as the highly influential ''Hallmarks of Aging'' published in 2013. While some biogerontologists support the SENS program, others contend that the ultimate goals of de Grey's programme ...

Cyberware
Cyberware refers to technology that integrates directly with the human nervous system, typically through implants or interfaces that enable communication between machines and the body. Once largely a concept within ''science fiction'', cyberware is now an emerging field of biomedical research and '' neurotechnology'', with applications ranging from brain–computer interfaces to advanced prosthetics. The term encompasses both sensory-enhancing implants and control systems that translate neural signals into digital outputs. While still in its early stages, cyberware has gained renewed interest in the 21st century through companies like '' Neuralink'' and '' BrainGate'', as well as ongoing research into human–machine symbiosis. Interfaces ("headware") It is the most difficult object to implement, but it is also the most important in terms of interfacing directly with the mind. In science fiction the data-jack is the envisioned I/O port for the brain. Its job is to translate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Brain–computer Interface
A brain–computer interface (BCI), sometimes called a brain–machine interface (BMI), is a direct communication link between the brain's electrical activity and an external device, most commonly a computer or robotic limb. BCIs are often directed at researching, Brain mapping, mapping, assisting, Augmented cognition, augmenting, or repairing human Cognitive skill, cognitive or Sensory-motor coupling, sensory-motor functions. They are often conceptualized as a human–machine interface that skips the intermediary of moving body parts (e.g. hands or feet). BCI implementations range from non-invasive (EEG, Magnetoencephalography, MEG, MRI) and partially invasive (ECoG and endovascular) to invasive (microelectrode array), based on how physically close electrodes are to brain tissue. Research on BCIs began in the 1970s by Jacques Vidal at the University of California, Los Angeles (UCLA) under a grant from the National Science Foundation, followed by a contract from the Defense Adva ...

Neural Implants
Brain implants, often referred to as neural implants, are technological devices that connect directly to a biological subject's brain – usually placed on the surface of the brain, or attached to the brain's cortex. A common purpose of modern brain implants and the focus of much current research is establishing a biomedical prosthesis circumventing areas in the brain that have become dysfunctional after a stroke or other head injuries. This includes sensory substitution, e.g., in vision. Other brain implants are used in animal experiments simply to record brain activity for scientific reasons. Some brain implants involve creating interfaces between neural systems and computer chips. This work is part of a wider research field called brain–computer interfaces. (Brain–computer interface research also includes technology such as EEG arrays that allow interface between mind and machine but do not require direct implantation of a device.) Neural implants such as deep brain stimula ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Neurotechnology
Neurotechnology encompasses any method or electronic device which interfaces with the nervous system to monitor or modulate neural activity. Common design goals for neurotechnologies include using neural activity readings to control external devices such as neuroprosthetics, altering neural activity via neuromodulation to repair or normalize function affected by neurological disorders, or augmenting cognitive abilities. In addition to their therapeutic or commercial uses, neurotechnologies also constitute powerful research tools to advance fundamental neuroscience knowledge. Some examples of neurotechnologies include deep brain stimulation, photostimulation based on optogenetics and photopharmacology, transcranial magnetic stimulation, transcranial electric stimulation and brain–computer interfaces, such as cochlear implants and retinal implants. The field of neurotechnology has been around for nearly half a century but has only reached maturity in the last twenty years. D ...
