Thoughts on the 2018 Eurosymposium on Healthy Ageing

Posted by in categories: biotech/medical, chemistry, life extension, media & arts

Thoughts on the Eurosymposium on Healthy Ageing held by Heales in Brussels.


When I first learned about the possibility of achieving human rejuvenation through biotechnological means, little did I know that this would lead me to meet many of the central figures in the field during a conference some seven years later—let alone that I would be speaking at the very same event. Yet, I’ve had the privilege to attend the Fourth Eurosymposium on Healthy Ageing (EHA) held in Brussels on November 8–10, an experience that gave me a feel of just how real the prospect of human rejuvenation is.

A friendly, welcoming environment

MIT Knows That AI Is The Future

Posted by in categories: biological, chemistry, robotics/AI

MIT has launched the Stephen A. Schwarzman College of Computing, a $1 billion center dedicated to “reshaping its academic program” around AI. The idea, said MIT president L. Rafael Reif, is to use AI, machine learning and data science with other academic disciplines to “educate the bilinguals of the future,” defining bilingual as those working in biology, chemistry, politics, history and linguistics with computing skills that can be used in their field.

Engineers build smallest integrated Kerr frequency comb generator

Posted by in categories: biotech/medical, chemistry, computing, engineering, security

Optical frequency combs can enable ultrafast processes in physics, biology, and chemistry, as well as improve communication and navigation, medical testing, and security. The Nobel Prize in Physics 2005 was awarded to the developers of laser-based precision spectroscopy, including the optical frequency comb technique, and microresonator combs have become an intense focus of research over the past decade.

A major challenge has been how to make such comb sources smaller and more robust and portable. In the past 10 years, major advances have been made in the use of monolithic, chip-based microresonators to produce such combs. While the microresonators generating the are tiny—smaller than a human hair—they have always relied on external lasers that are often much larger, expensive, and power-hungry.

Researchers at Columbia Engineering announced today in Nature that they have built a Kerr frequency comb generator that, for the first time, integrates the together with the , significantly shrinking the system’s size and power requirements. They designed the laser so that half of the laser cavity is based on a semiconductor waveguide section with high optical gain, while the other half is based on waveguides, made of , a very low-loss material. Their results showed that they no longer need to connect separate devices in the lab using fiber—they can now integrate it all on photonic chips that are compact and energy efficient.

Artificial enzymes convert solar energy into hydrogen gas

Posted by in categories: bioengineering, biological, chemistry, genetics, solar power, sustainability

In a new scientific article, researchers at Uppsala University describe how, using a completely new method, they have synthesised an artificial enzyme that functions in the metabolism of living cells. These enzymes can utilize the cell’s own energy, and thereby enable hydrogen gas to be produced from solar energy.

Hydrogen gas has long been noted as a promising carrier, but its production is still dependent on fossil raw materials. Renewable gas can be extracted from water, but as yet the systems for doing so have limitations.

In the new article, published in the journal Energy and Environmental Science, an interdisciplinary European research group led by Uppsala University scientists describe how convert into hydrogen gas. This entirely new method has been developed at the University in the past few years. The technique is based on photosynthetic microorganisms with genetically inserted enzymes that are combined with synthetic compounds produced in the laboratory. Synthetic biology has been combined with synthetic chemistry to design and create custom artificial enzymes inside living organisms.

An Interview with Mike Bonkowski

Posted by in categories: biotech/medical, chemistry, genetics, life extension

Today, we have an interview with Dr. Michael Bonkowski, an expert on NAD+ biology and aging from the David Sinclair Lab, Harvard Medical School.

Michael Bonkowski aims to advance our understanding of the links between metabolism, aging, and age-associated diseases. He has published 35 peer-reviewed journal articles and has conducted multiple successful longevity studies. In Dr. David Sinclair’s lab, his research efforts are focused on the role of nutrient sensors’ regulation of endocrine signaling and aging in the mouse. He is also working on direct and indirect ways to drive the activity of these nutrient sensors by using dietary manipulations, small molecules, and chemical treatments.

Michael is trained as a pharmacologist, physiologist, and animal scientist. Some of his areas of expertise include animal physiology, genetics, glucose, and insulin homeostasis, metabolism, assay development, protein biochemistry, and transmission electron microscopy imaging.

Tenfold improvement in liquid batteries mean electric car refuelling could take minutes

Posted by in categories: chemistry, energy, sustainability, transportation

One of the biggest drawbacks of electric vehicles – that they require hours and hours to charge – could be obliterated by new type of liquid battery that is roughly ten times more energy-dense than existing models, according to Professor Lee Cronin, the Regius Chair of Chemistry at the University of Glasgow, UK.

What’s so special about this liquid, or flow, battery?

“A normal electric vehicle has a solid battery, and when that runs out of charge you have to recharge it by plugging it in to a power socket. This takes half an hour or so if you find a rapid charger at a motorway service station, or up to 12 hours at home. Our battery, however, is made of a liquid rather than a solid. If you run out of charge, you could in principle pump out the depleted liquid and – like a regular petrol or diesel vehicle – refill it with liquid that is ready-charged. And that would take minutes.”
