Genetic “extinction” technology rejected

Posted by in categories: bioengineering, biological, existential risks, genetics, government

OAHU, HAWAI’I — As thousands of government representatives and conservationists convene in Oahu this week for the 2016 World Conservation Congress, international conservation and environmental leaders are raising awareness about the potentially dangerous use of gene drives — a controversial new synthetic biology technology intended to deliberately cause targeted species to become extinct.

Members of the International Union for the Conservation of Nature (IUCN), including NGOs, government representatives, and scientific and academic institutions, overwhelmingly voted to adopt a de facto moratorium on supporting or endorsing research into gene drives for conservation or other purposes until the IUCN has fully assessed their impacts. News of the August 26 digital vote comes as an important open letter to the group is being delivered.

Scientists and environmental experts and organizations from around the globe have advocated for a halt to proposals for the use of gene drive technologies in conservation. Announced today, a long list of environmental leaders, including Dr. Jane Goodall, DBE, genetics professor and broadcaster Dr. David Suzuki, Dr. Fritjof Capra, entomologist Dr. Angelika Hilbeck, Indian environmental activist Dr. Vandana Shiva and organic pioneer and biologist Nell Newman, have lent their support to the open letter: “A Call for Conservation with a Conscience: No Place for Gene Drives in Conservation.” The letter states, in part: “Gene drives, which have not been tested for unintended consequences, nor fully evaluated for ethical and social impacts, should not be promoted as conservation tools.”

Surprisingly, Plant Microbes May Be An Answer To Our Growing Food Needs

Posted by in categories: biological, food, sustainability, transportation

By Sveta McShane: Organizations as diverse as the United Nations and Monsanto are in agreement that we need to double our food production globally by 2050 to feed the world’s population…

Awaken

But our current agricultural process is one of the biggest contributors to global warming. It emits more greenhouses gases than all the world’s cars combined and is a major consumer and polluter of our precious water resources.

Tapping the unused potential of photosynthesis

Posted by in categories: biological, food, sustainability

Scientists from the University of Southampton have reengineered the fundamental process of photosynthesis to power useful chemical reactions that could be used to produce biofuels, pharmaceuticals and fine chemicals.

Photosynthesis is the pivotal biological reaction on the planet, providing the food we eat, the oxygen we breathe and removing CO2 from the atmosphere.

Photosynthesis in plants and algae consists of two reactions, the light-reactions absorb light energy from the sun and use this to split water (H2O) into electrons, protons and oxygen and the dark-reactions which use the electrons and protons from the light reactions to ‘fix’ CO2 from the atmosphere into simple sugars that are the basis of the food chain. Importantly, the light reactions have a much higher capacity than the dark reactions resulting in much of the absorbed being wasted as heat rather than being used to ‘fix’ CO2.

A New Way to Create Synthetic Proteins Could Lead to More Flexible Designs

Posted by in categories: biological, nanotechnology, singularity

Nice advancement for the nanomaterials space particularly as we look at ways to improve machines, devices, BMI, living buildings or other living structures, etc. Definitely advances efforts around Singularity.


Proteins perform a myriad of functions essential for life. They also make up important and useful biological materials, for example spider silk, which is exceptionally strong but still flexible.

The ability to design completely new proteins would help scientists create nanomaterials that, like spider silk, have a specific microstructure that confers useful properties.

Dolomite Lends a Helping Hand to Synthetic Biology Research

Posted by in categories: bioengineering, biological, computing

Excellent opportunity.


Dolomite microfluidic chips are helping researchers from the Biodesign Institute at Arizona State University (ASU) to develop novel enzymes capable of polymerising synthetic nucleotides.

dolomiteUsing these chips, the team has created a droplet-based optical polymerase sorting (DrOPS) technique allowing rapid screening for novel polymerase activities in uniform water-in-oil microcompartments. The team’s leader, Professor John C. Chaput – formerly at ASU and currently at the University of California, Irvine – explained: “The creation of synthetic nucleic acids is of great interest to synthetic biologists but, because they are not found in nature, wild type polymerases struggle to process them. To overcome this issue, we are developing novel polymerases using directed evolution in water-in-oil microcompartments. The DrOPS methodology has significant advantages over traditional methods, which are both labour intensive and impractical to perform on a large scale due to the amount of precious artificial nucleotide reagents required for screening.”

Nanostructured Device Purifies Water With Light

Posted by in categories: biological, nanotechnology

In many parts of the world, the only way to make germy water safe is by boiling, which consumes precious fuel, or by putting it out in the sun in a plastic bottle so ultraviolet rays will kill the microbes. But because UV rays carry only 4 percent of the sun’s total energy, the UV method takes six to 48 hours, limiting the amount of water people can disinfect this way.

Liquid Metals to “Soft-Wire” Elastic Electronics

Posted by in categories: bioengineering, biological, particle physics, robotics/AI

“Liquid Metals to “Soft-Wire” Elastic Electronics”

A few years ago, some friends shared with me an amazing experiment of theirs involving liquid/ fluid base circuitry. Definitely is amazing; and is going to be amazing in where we are taking this type of technology along with synthetic biology.


The shape-shifting metals behind the T-1000 android assassin in the sci-fi movie Terminator 2 may not remain science fiction for long with the development of self-propelling liquid metals that could lead to the replacement of solid state circuits by elastic electronics.

A Brain Circuit to Push Past Nutritional Stress

Posted by in categories: biological, food, neuroscience

When we go hungry, we have the ability to ignore the urge to eat such that we can carry out the task at hand. It has long been known that the brain is involved in such decisions. But how the brain coordinates the response to nutritional stress so that the body can function normally is not understood very well. Now, researchers from the National Centre for Biological Sciences (NCBS), Bangalore, have discovered a brain circuit that allows fruit flies to take a major .
