Jonathan "Joe" Betts-LaCroix (born Jonathan Betts February 26, 1962) is an American scientist and entrepreneur known for his discoveries in biophysics and for creating the world's smallest personal computer. He is working to optimize medical research priorities in the U.S.
Joe Betts-LaCroix was born and raised in Oregon. He graduated from the school with "D average", and "spent the next six years living in a shared house with 'musicians, artists and weirdos'". He did some "electronics, hardware and software work for local businesses" at this time. When his girlfriend went to Harvard, he decided to follow, and after getting "straight A's" at a local college, he then transferred to Harvard, where he studied environmental geoscience. [1]
Beginning in earth sciences at Harvard, Betts-LaCroix contributed to the field of long-term regulation of oxygen on Earth over multi-100 Million-year timespans, quantifying the effect of the burial efficiency of organic carbon as a feedback mechanism. [2]
At MIT, he designed and built an autonomous, robotic system that enables research into ocean circulation patterns and climate change, by operating untended for up to one year at sea on battery power and collecting hyper-pure water samples at predetermined intervals. [3]
In work at Caltech, Betts-LaCroix moved into biophysics, publishing a paper in Science that has been cited by more than 700 subsequent scientific works. [4] In this work, he, along with David Beratan and José Onuchic,proved for the first time that electron-transfer rates in proteins are determined by the electron orbital interactions in the protein structure. [5]
In 2000, Betts-LaCroix cofounded OQO, a computer hardware and software OEM credited by the Guinness World Records as having created the world's smallest Windows PC. [6] This created a new category of mobile computing devices between PDAs and laptops, which were initially dubbed the "Ultra Personal Computer", and which subsequently became known as the "Netbook". The device won many awards for its innovation, aesthetics and functionality. [7] [8] [9] [10] [11]
After OQO, Betts-Lacroix was active in Silicon Valley as a lecturer and mentor for CEOs of start up companies. [12]
Betts-LaCroix has participated in the Quantified Self movement since the beginning, [13] and has given numerous presentations on aspects of self experimentation and tracking, including experiments in the 28-Hour day. [14]
In 2010, he joined startup Halcyon Molecular to lead its automation efforts. [15] Halcyon, funded by, among others, Elon Musk and Peter Thiel, attempted to sequence human DNA using electron microscopes. The underlying goal of Halcyon's work was to make meaningful progress in understanding human biology in order to improve medicine. [15]
Following the theme of improving medicine, Betts-LaCroix founded the Health Extension Foundation in 2012. [16] The efforts of the people working in Health Extension are motivated by recognizing that
In 2013, Betts-LaCroix cofounded Vium, which has raised $33M to accelerate the development of new medical therapies by automating in-vivo research. [18] [19] Vium launched publicly in 2016, [20] and was later acquired by Recursion in 2020. [21]
Betts-LaCroix is also a biotech angel investor in such companies as StemCentrx, Recursion Pharma [22] and Spring Discovery, [23] as well as a part-time contributor at Y Combinator. [24]
In 2020, Betts-LaCroix cofounded Retro Biosciences, which emerged out of stealth with $180 million in funding from OpenAI CEO Sam Altman [25] to focus on extending healthy human lifespans. [26] Retro works on autophagy, the rejuvenation of blood plasma and on partial cell reprogramming. [1]
The enzyme cytochrome c oxidase or Complex IV, is a large transmembrane protein complex found in bacteria, archaea, and the mitochondria of eukaryotes.
Combinatory logic is a notation to eliminate the need for quantified variables in mathematical logic. It was introduced by Moses Schönfinkel and Haskell Curry, and has more recently been used in computer science as a theoretical model of computation and also as a basis for the design of functional programming languages. It is based on combinators, which were introduced by Schönfinkel in 1920 with the idea of providing an analogous way to build up functions—and to remove any mention of variables—particularly in predicate logic. A combinator is a higher-order function that uses only function application and earlier defined combinators to define a result from its arguments.
In combinatory logic for computer science, a fixed-point combinator, is a higher-order function that returns some fixed point of its argument function, if one exists.
Paul Graham is an English-American computer scientist, writer, entrepreneur and investor. His work has included the programming language Lisp, the startup Viaweb, co-founding the startup accelerator and seed capital firm Y Combinator, his essays, and Hacker News.
Life extension is the concept of extending the human lifespan, either modestly through improvements in medicine or dramatically by increasing the maximum lifespan beyond its generally-settled biological limit of around 125 years. Several researchers in the area, along with "life extensionists", "immortalists", or "longevists", postulate that future breakthroughs in tissue rejuvenation, stem cells, regenerative medicine, molecular repair, gene therapy, pharmaceuticals, and organ replacement will eventually enable humans to have indefinite lifespans through complete rejuvenation to a healthy youthful condition (agerasia). The ethical ramifications, if life extension becomes a possibility, are debated by bioethicists.
Metalloprotein is a generic term for a protein that contains a metal ion cofactor. A large proportion of all proteins are part of this category. For instance, at least 1000 human proteins contain zinc-binding protein domains although there may be up to 3000 human zinc metalloproteins.
An air ioniser is a device that uses high voltage to ionise air molecules. Negative ions, or anions, are particles with one or more extra electrons, conferring a net negative charge to the particle. Cations are positive ions missing one or more electrons, resulting in a net positive charge. Some commercial air purifiers are designed to generate negative ions. Another type of air ioniser is the electrostatic discharge (ESD) ioniser used to neutralise static charge.
Peter Agre is an American physician, Nobel Laureate, and molecular biologist, Bloomberg Distinguished Professor at the Johns Hopkins Bloomberg School of Public Health and Johns Hopkins School of Medicine, and director of the Johns Hopkins Malaria Research Institute. In 2003, Agre and Roderick MacKinnon shared the 2003 Nobel Prize in Chemistry for "discoveries concerning channels in cell membranes." Agre was recognized for his discovery of aquaporin water channels. Aquaporins are water-channel proteins that move water molecules through the cell membrane. In 2009, Agre was elected president of the American Association for the Advancement of Science (AAAS) and became active in science diplomacy.
In chemistry, a non-covalent interaction differs from a covalent bond in that it does not involve the sharing of electrons, but rather involves more dispersed variations of electromagnetic interactions between molecules or within a molecule. The chemical energy released in the formation of non-covalent interactions is typically on the order of 1–5 kcal/mol. Non-covalent interactions can be classified into different categories, such as electrostatic, π-effects, van der Waals forces, and hydrophobic effects.
A photosynthetic reaction center is a complex of several proteins, pigments, and other co-factors that together execute the primary energy conversion reactions of photosynthesis. Molecular excitations, either originating directly from sunlight or transferred as excitation energy via light-harvesting antenna systems, give rise to electron transfer reactions along the path of a series of protein-bound co-factors. These co-factors are light-absorbing molecules (also named chromophores or pigments) such as chlorophyll and pheophytin, as well as quinones. The energy of the photon is used to excite an electron of a pigment. The free energy created is then used, via a chain of nearby electron acceptors, for a transfer of hydrogen atoms (as protons and electrons) from H2O or hydrogen sulfide towards carbon dioxide, eventually producing glucose. These electron transfer steps ultimately result in the conversion of the energy of photons to chemical energy.

Tsien was also a pioneer of calcium imaging.
Samuel Harris Altman is an American entrepreneur and investor best known as the CEO of OpenAI since 2019. He is also the chairman of clean energy companies Oklo Inc. and Helion Energy. Altman is considered to be one of the leading figures of the AI boom. He dropped out of Stanford University after two years and founded Loopt, a mobile social networking service, raising more than $30 million in venture capital. In 2011, Altman joined Y Combinator, a startup accelerator, and was its president from 2014 to 2019.
Bacterial nanowires are electrically conductive appendages produced by a number of bacteria most notably from the Geobacter and Shewanella genera. Conductive nanowires have also been confirmed in the oxygenic cyanobacterium Synechocystis PCC6803 and a thermophilic, methanogenic coculture consisting of Pelotomaculum thermopropionicum and Methanothermobacter thermoautotrophicus. From physiological and functional perspectives, bacterial nanowires are diverse. The precise role microbial nanowires play in their biological systems has not been fully realized, but several proposed functions exist. Outside of a naturally occurring environment, bacterial nanowires have shown potential to be useful in several fields, notably the bioenergy and bioremediation industries.

Quantified self refers both to the cultural phenomenon of self-tracking with technology and to a community of users and makers of self-tracking tools who share an interest in "self-knowledge through numbers". Quantified self practices overlap with the practice of lifelogging and other trends that incorporate technology and data acquisition into daily life, often with the goal of improving physical, mental, and emotional performance. The widespread adoption in recent years of wearable fitness and sleep trackers such as the Fitbit or the Apple Watch, combined with the increased presence of Internet of things in healthcare and in exercise equipment, have made self-tracking accessible to a large segment of the population.
