‘Second skin’ protects soldiers from biological and chemical agents

Posted by in categories: biological, military

Amazing and can serve many areas.


(DOE/Lawrence Livermore National Laboratory) In work that aims to protect soldiers from biological and chemical threats, a team of Lawrence Livermore National Laboratory scientists has created a material that is highly breathable yet protective from biological agents.

This material is the first key component of futuristic smart uniforms that also will respond to and protect from environmental chemical hazards. The research appears in the July 27 edition of the journal, Advanced Materials.

Cell biologists should specialize, not hybridize

Very true POV.


Dry cell biologists, who bridge computer science and cell biology, should have a pivotal role in driving effective team science, says Assaf Zaritsky2.

Smart bricks would enable walls capable of generating electricity, clean water and oxygen

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

A lot of things are becoming “smart” these days, but bricks might not be something you’d expect to be added to the list. On the way to buildings that act like “large-scale living organisms,” scientists at the University of the West of England (UWE Bristol) are developing smart bricks that would make use of microbes to recycle wastewater, generate electricity and produce oxygen.

Microbial fuel cells (MFCs), which will be embedded in the bricks to give them their “smart” capabilities, have proven handy in the past, with researchers demonstrating how they can be used to generate electricity from human urine, dead flies or just plain old mud.

“Microbial fuel cells are energy transducers that exploit the metabolic activity of the constituent microbes to break down organic waste and generate electricity,” says Ioannis Ieropoulos, professor at UWE Bristol’s Robotics Laboratory. “This is a novel application for MFC modules to be made into actuating building blocks as part of wall structures. This will allow us to explore the possibility of treating household waste, generating useful levels of electricity, and have ‘active programmable’ walls within our living environments.”

Beware the Rise of Gerontocracy: Some Hard Lessons for Transhumanism, Not Least from Brexit

Posted by in categories: aging, biological, ethics, futurism, governance, government, homo sapiens, human trajectories, life extension, neuroscience, policy, strategy, thought controlled, transhumanism

Transhumanists will know that the science fiction author Zoltan Istvan has unilaterally leveraged the movement into a political party contesting the 2016 US presidential election. To be sure, many transhumanists have contested Istvan’s own legitimacy, but there is no denying that he has generated enormous publicity for many key transhumanist ideas. Interestingly, his lead idea is that the state should do everything possible to uphold people’s right to live forever. Of course, he means to live forever in a healthy state, fit of mind and body. Istvan cleverly couches this policy as simply an extension of what voters already expect from medical research and welfare provision. And while he may be correct, the policy is fraught with hazards – especially if, as many transhumanists believe, we are on the verge of revealing the secrets to biological immortality.

In June, Istvan and I debated this matter at Brain Bar Budapest. Let me say, for the record, that I think that we are sufficiently close to this prospect that it is not too early to discuss its political and economic implications.

Two months before my encounter with Istvan, I was on a panel at the Edinburgh Science Festival with the great theorist of radical life extension Aubrey de Grey, where he declared that people who live indefinitely will seem like renovated vintage cars. Whatever else, he is suggesting that they would be frozen in time. He may actually be right about this. But is such a state desirable, given that throughout history radical change has been facilitated generational change? Specifically, two simple facts make the young open to doing things differently: The young have no memory of past practices working to anyone else’s benefit, and they have not had the time to invest in those practices to reap their benefits. Whatever good is to be found in the past is hearsay, as far as the young are concerned, which they are being asked to trust as they enter a world that they know is bound to change.

Questions have been already raised about whether tomorrow’s Methuselahs will wish to procreate at all, given the time available to them to realize dreams that in the past would have been transferred to their offspring. After all, as human life expectancy has increased 50% over the past century, the birth rate has correspondingly dropped. One can only imagine what will happen once ageing can be arrested, if not outright reversed!

Repurposing the ribosome for synthetic biology

Posted by in categories: bioengineering, biological, education, sustainability

Over the past several years, Northwestern Engineering’s Michael Jewett did the seemingly impossible. He overcame the critical barrier to making mutant ribosomes, the core catalyst in cells that are responsible for life.

Now, with funding from the Department of Defense’s Multidisciplinary University Research Initiatives (MURI) program, Jewett is ready to take this research to the next level. Along with a multi-school team, he plans to use engineer and repurpose the ribosome to make new kinds of polymers for flow batteries.

“We are in a new era of biomaterial design,” Jewett said. “So far, the ribosome has been this untouchable biomolecular machine — one that we couldn’t engineer or modify. Now, armed with recent advances in our ability to construct new versions, new applications may only be limited by our imagination.”

Sharper than living matter permits

Posted by in categories: biological, quantum physics

Researchers at the Max Planck Institute of Molecular Physiology in Dortmund have now found a way to pinpoint the positions of individual molecules while at the same time measuring their activity and interactions in the same living cell. A dedicated cooling protocol on a microscope allows to pause cellular life at subzero temperatures, to let it continue to live again after warming. From the series of individual snapshots obtained, the researchers are able to form a precise spatial-temporal picture of the activity patterns of individual molecules within individual cells.

Fluorescence microscopy allows seeing where biological molecules are in cells. However, what Werner Heisenberg formulated for quantum physics to a certain extent has its analogy in biology: In the living state one can observe the collective movement of molecules in cells, which makes it however difficult to determine their exact positions. Paradoxically, the molecular dynamics that sustain life have to be halted to record the position of molecules using high-resolution fluorescence microscopy.

Living matter maintains its structure by energy consumption, which results in dynamic molecular patterns in cells that are difficult to observe by fluorescence microscopy, because the molecules are too numerous and their movements too fast. To tackle this problem a choice needs to be made: to precisely record the position of the molecules in a ‘dead’ state or to follow their collective behaviour in the living state. Although researchers have been able to stop movements in cells by chemical fixation, such methods lead to irreversible cell death and the acquired images of molecular patterns are not representative of a living system.
