Biohacking: The effort to optimize health and extend life through technology

Biohacking seeks to optimize human health and performance through everything from simple lifestyle adjustments to more radical interventions like body modifications and experimental technology. At its core, biohacking covers a wide spectrum—ranging from improving sleep and focus to implanting devices that integrate technology with the human body.

The origin of cyborgs

The term "cyborg" was coined in a 1960 academic paper discussing what alterations humans would need to undergo to survive in extraterrestrial environments, a venture far "more logical than providing an earthly environment" in space. According to authors Manfred E. Clynes and Nathan S. Kline, Cyborgs with a capital C have incorporated exogenous components that extend their ability to adapt to new environments.

Mind-controlled bionic arms use nerve implants to restore sensation and movement

Unlike traditional prosthetics that rely on surface electrodes or mechanical parts, this system uses implanted titanium and nerve-connected electrodes to enable a seamless brain-to-arm connection. Patients train in virtual reality with their implanted signals before using the physical prosthesis.

The history of skull modification

The ancient Maya people sometimes modified their skulls to appear more conical. Body modification has been a human pastime for literal ages, from piercings to bindings and everything in between. Modifying one's skull shape may have been a way to symbolize status, beauty, belonging, or belief. The health impacts of such practices are still debated. This article explores the history and health impacts of skull modification, also known as artificial cranial deformation.

'Grunge' was initially used as an insult

The first known use of "grunge" to describe music is believed to be by Mark Arm, a Seattle scenester, who mocked his own band by writing, "Pure grunge! Pure noise! Pure shit!" By 1987, it'd caught on as a more earnest descriptor for a sludgy mix of punk and metal: Sub Pop Records cofounder Bruce Pavitt described the band Green River as "ultra-loose grunge that destroyed the morals of a generation."

Body horror is a subgenre that uses anxieties about appearance

Particle beams can be used to alter the surface properties of artificial joints

Surface hardening and embedding specific elements or coatings can improve the biocompatibility and bone tissue integration of these implants. Particle accelerators are significant sources of the radioisotopes needed in medical diagnostics, and microwave linear accelerators are used in the majority of cancer irradiation treatments.

Microgravity environments improve the success of 3D bioprinting

Gravity can cause gaps, such as those in the chambers of a 3D-printed heart, to collapse before stem cells, hydrogels, and biochemicals bind together during the bioprinting process. Rather than Earth's surface, some bioprinting is done on the International Space Station, where defective organs are also printed to test treatment methods.

Gamma Knife surgery uses incredibly precise, high-energy light to treat patients

A form of brain stereotactic radiosurgery, this non-invasive technology concentrates beams of light onto specific tumors to damage the DNA of malignant cells, killing them. The gamma rays used are in the same part of the electromagnetic spectrum as those produced in nuclear reactions, cosmic ray collisions, and radioactive decay.

The history of torturing robots

When machines fail, its easy to get mad and even give them a good kick. But as humanoid robots become more sophisticated, the degree to which people abuse them has shifted, depending on how much emotion the robot expresses. Studies revealed when robots were programmed to cry during distress, participants felt empathy. Learn more about the history of human abuse of robots here.

Writer William Gibson invented the term 'cyberspace'

The science-fiction writer coined the term in his 1982 short story "Burning Chrome" to describe "a consensual hallucination experienced daily by billions of legitimate operators, in every nation, by children being taught mathematical concepts...A graphic representation of data abstracted from the banks of every computer in the human system. Unthinkable complexity. Lines of light ranged in the nonspace of the mind, clusters and constellations of data. Like city lights, receding."

The gray area that makes PEDs seem like leveling up to hardcore athletes

Doping in sports is broadly condemned as unsafe and unfair. Significant controversies in major sports, including baseball and cycling, have been prompted by the widespread use of performance-enhancing drugs, which are described as clear-cut dangers and abuses of the rules. But to many competitors, the line between a PED and the next smart technique to adopt is unclear. This podcast episode explores that gray reality.

How grudges mostly hurt ourselves

Grudges feel like revenge against those who have done us some wrong and are very common. In this "Hidden Brain" podcast, psychologists explain how grudges end up only hurting us rather than those we hold them against. By using historical examples, the researchers show the counterintuitive danger of grudges and how people can learn how to avoid them.

How microchips are made

Our increasingly electronic world depends on tiny devices called microchips to function. It takes half a year to create one, which is approximately the size of a fingernail. Engineering them is a highly involved process that starts with silicon-rich sand and eventually turns into billions of transistors packed into one small area. Watch this video to understand the complex feat of creating microchips and how they’re relevant to our daily life.
