The laws of nature make life on other planets inevitable — according to this groundbreaking theory

Posted by in categories: alien life, biological, chemistry, physics

According to theoretical physicist and super-genius Stephen Hawking, “The human race is just a chemical scum on a moderate-sized planet orbiting round a very average star in the outer suburb of one among a hundred billion galaxies.” Indeed, to most modern scientists we are nothing more than an entirely random ‘happy accident’ that likely would not occur if we were to rewind the tape of the universe and play it again. But what if that is completely wrong? What if life is not simply a statistical anomaly, but instead an inevitable consequence of the laws of physics and chemistry?

A new theory of the origin of life, based firmly on well-defined physics principles, provides hefty support for the notion that biological life is a “cosmic imperative”. In other words, organic life had to eventually emerge. If such a theory were true, it would mean that it is very likely that life is widespread throughout the universe.

Scientists have found a set of genetic switches needed to regrow limbs

Posted by in categories: biological, genetics

Could humans regrow limbs? Genetic switches for regenerating tissue are traced back 420 million years…


But ultimately the researchers hope to see if the mechanism could be exploited to allow humans to regenerate limbs themselves, although they warn it could be several decades before that is possible.

Dr Yin said: ‘It depends on the pace of discovery, which is heavily dependent on funding.’

New way to model molecules

Magine a future in which hyper-efficient solar panels provide renewable sources of energy, improved water filters quickly remove toxins from drinking water, and the air is scrubbed clean of pollution and greenhouse gases. That could become a reality with the right molecules and materials.

Scientists from Harvard and Google have taken a major step toward making the search for those molecules easier, demonstrating for the first time that a quantum computer could be used to model the electron interactions in a complex molecule. The work is described in a new paper published in the journal Physical Review X by Professor Alán Aspuru-Guzik from the Department of Chemistry and Chemical Biology and several co-authors.

“There are a number of applications that a quantum computer would be useful for: cryptography, machine learning, and certain number-theory problems,” Aspuru-Guzik said. “But one that has always been mentioned, even from the first conceptions of a quantum computer, was to use it to simulate matter. In this case, we use it to simulate chemistry.”

‘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.

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.”
