“I don’t want to get wrinkles or gray hair, and I want to be able to lift weights and run forever,” says Robinton. “It’s important to be grounded in reality, but I feel the science is closer than ever before.”
Here are the groundbreaking technologies that may one day help us reclaim our youth.
Transistors, those tiny electrical switches that process signals and data, are the brain power behind every electronic device – from laptops and smartphones to your digital thermostat. As they continue to shrink in size, computers have become smaller, more powerful, and more pervasive. However, as we look to build squishy, human-friendly machines that have the look and feel of soft natural organisms, we need to look beyond the rigid materials used to create electrical switches and circuits.
Mechanical engineers Carmel Majidi and James Wissman of the Soft Machines Lab at Carnegie Mellon University have been looking at new ways to create electronics that are not just digitally functional but also soft and deformable. Rather than making circuits from rigid metals like copper or silver, they use a special metal alloy that is liquid at room temperature. This alloy, made by mixing indium and gallium, is a non-toxic alternative to mercury and can be infused in rubber to make circuits that are as soft and elastic as natural skin.
Teaming up with Michael Dickey at North Carolina State University, they recently discovered that liquid metal electronics are not only useful for stretchable circuit wiring but can also be used to make electrical switches. These fluidic transistors work by opening and closing the connection between two liquid metal droplets. When a voltage drop is applied in one direction, the droplets move towards each other and coalesce to form a metallic bridge for conducting electricity. When voltage is applied in a different direction, the droplets spontaneously break apart and turn the switch to open. By quickly alternating between an open and closed and open switch state with only a small amount of voltage, the researchers were able to mimic the properties of a conventional transistor.

In a step towards creating a new class of electronics that look and feel like soft, natural organisms, mechanical engineers at Carnegie Mellon University are developing a fluidic transistor out of a metal alloy of indium and gallium that is liquid at room temperature. From biocompatible disease monitors to shape-shifting robots, the potential applications for such squishy computers are intriguing.
Until recently, the only example of liquid electronics were microswitches made up of tiny glass tubes with a bead of mercury inside that closes the switch when it rolls between two wires. Essentially, the fluidic transistor is a much more sophisticated switch that’s made of a liquid metal alloy that is non-toxic, so it can be infused into rubber to create soft, stretchable circuits.
Unlike the mercury switch, where tilting the vial closes the circuit, the fluidic transistor works by opening and closing the connection between metal droplets using the direction of the voltage. When it flows in one direction, the droplets combine and the circuit closes. If it flows the other way, the droplet splits and the circuit opens.

“Room temperature quantum sensors can be mounted directly on the scalp of any subject. This will give us a projected four-fold increase in sensitivity for adults, but the sensitivity could potentially be up to a 15 or 20 fold increase for children or babies.”
A £1.6 million collaborative project between scientists at the University of Nottingham and University College London (UCL) is looking to improve the way we map the human brain. Focusing on the development of magnetoencephalography (MEG), researchers have 3D printed a prototype helmet that may yield quadruple the sensitivity of current MEG devices.

In addition, a small number of posters will be selected for oral presentation. Poster topics should lie within the scope of the conference: Research contributing to the eventual postponement of age-related decline in health, with an emphasis on measures that repair damage rather than slowing its creation. Poster submissions are due on January 15, 2018.
To submit your poster go to.
Undoing Aging will include poster sessions on the first two evenings. If you wish to present a poster, please submit the details on this page. A small number of posters will be selected for oral presentation; those selected should also prepare a poster.

Following a $200 million investment this summer — the largest agriculture-tech funding round in history — vertical farming startup Plenty is expanding beyond its Bay Area roots.
The company is opening a second farm in the greater Seattle area, Plenty CEO Matt Barnard told Business Insider. Located in Kent, Washington, the 100,000-square-foot warehouse facility will grow 4.5 million pounds of greens annually, which is enough to feed around 183,600 Americans, according to the USDA.
The new farm will officially start production in spring 2018. Instead of growing outdoors, Plenty grows its crops on glowing, LED-lit 20-foot-tall towers inside a former electronics distribution center in South San Francisco. The towers do not require soil, pesticides, or even natural sunlight.
