Producing ‘green’ energy from living plant ‘bio-solar cells’

Posted by in categories: biological, chemistry, food, solar power, sustainability

Though plants can serve as a source of food, oxygen and décor, they’re not often considered to be a good source of electricity. But by collecting electrons naturally transported within plant cells, scientists can generate electricity as part of a “green,” biological solar cell.

Now, researchers reporting in ACS Applied Materials & Interfaces have, for the first time, used a succulent plant to create a living “bio-solar cell” that runs on photosynthesis.

In all , from bacteria and fungi to and animals, electrons are shuttled around as part of natural, biochemical processes. But if electrodes are present, the cells can actually generate electricity that can be used externally. Previous researchers have created fuel cells in this way with bacteria, but the microbes had to be constantly fed. Instead, scientists, including Noam Adir’s team, have turned to photosynthesis to generate current.

Chemists create quantum dots at room temperature using lab-designed protein

Posted by in categories: biological, quantum physics

Nature uses 20 canonical amino acids as building blocks to make proteins, combining their sequences to create complex molecules that perform biological functions.

But what happens with the sequences not selected by nature? And what possibilities lie in constructing entirely new sequences to make novel (de novo) proteins bearing little resemblance to anything in nature?

In the underground movement known as, people are taking their health into their own hands. Biohacking ranges from people making simple lifestyle changes to extreme body modifications.

One popular form of focuses on nutrigenomics, where biohackers study how the foods they eat affect their genes over time. They believe they can map and track the way their diet affects genetic function. They use dietary restrictions and blood tests, while tracking their moods, energy levels, behaviors, and cognitive abilities.

New Research Reveals How Fear Get Stuck in Brains

Posted by in categories: biological, neuroscience

A biological mechanism has been identified by researchers at Linköping University in Sweden that increases the strength with which fear memories are stored in the brain The research, conducted in rats, was published in the scientific journal Molecular Psychiatry. It provides new insights into the processes behind anxiety-related disorders and identified shared mechanisms of anxiety and alcohol dependence.

The ability to feel fear is critical for escaping life-threatening circumstances and learning how to avoid them in the future. However, in certain conditions, such as post-traumatic stress disorder (PTSD

Post-traumatic stress disorder (PTSD) is a psychiatric disorder that develops in some people who have experienced or witnessed a shocking, scary, or dangerous event.

Scientists have provided a solution for humans to achieve immortality and come back from the dead

Posted by in categories: biological, life extension, solar power, sustainability

A Dyson Sphere is a megastructure that has not yet been built. Scientists conceive of it as a giant shell that encloses the sun.

Hypothetically, the Dyson Sphere will be lined with mirrors and solar panels that will collect the energy from the sun. This would be an unimaginable amount of energy.

In theory, the Dyson Sphere would be large enough that it could be a habitable place for humans and it would act as an artificial biosphere in the case that Earth’s supplies have dwindled. It would be a way to ensure survival for the human race.

The process algebra model: A new way of constructing reality

Posted by in categories: biological, mathematics, particle physics, quantum physics

The concept of ‘anti-realism’ is widely seen as a fact of life for many physicists studying the mysterious effects of quantum mechanics. However, it also seems to contradict the assumptions of many other fields of research. In his research, Dr William Sulis at McMaster University in Canada explores the issue from a new perspective, by using a novel mathematical toolset named the ‘process algebra model’. In suggesting that reality itself is generated by interacting processes more fundamental than quantum particles, his theories could improve researchers’ understanding of fundamental processes in a wide variety of fields.

The concept of ‘locality’ states that objects and processes can only be influenced by other objects and processes in their immediate surroundings. It is a fundamental aspect of many fields of research and underpins all of the most complex systems we observe in nature, including living organisms. “Biologists and psychologists have known for centuries that the physical world is dominated by processes which are characterized by factors including transformation, interdependence, and information”, Dr Sulis explains. “Organisms are born, develop, continually exchange physical components and information with their environment, and eventually die.”

Beyond biology, the principle of locality also extends to Einstein’s theory of special relativity. Since the speed of light sets a fundamental speed limit on all processes in the universe, the theory states that no process can occur if it has not been triggered by another event in its past, at a close enough distance for light to travel between them within the time separating them. In general, these theories are unified by a concept which physicists call ‘realism’. Yet despite this seemingly intuitive rule, physicists have increasingly come to accept the idea that it doesn’t present a full description of how all processes unfold.

Evidence for long-term potentiation in phospholipid membranes

Posted by in categories: biological, neuroscience

Biological supramolecular assemblies, such as phospholipid bilayer membranes, have been used to demonstrate signal processing via short-term synaptic plasticity (STP) in the form of paired pulse facilitation and depression, emulating the brain’s efficiency and flexible cognitive capabilities. However, STP memory in lipid bilayers is volatile and cannot be stored or accessed over relevant periods of time, a key requirement for learning. Using droplet interface bilayers (DIBs) composed of lipids, water and hexadecane, and an electrical stimulation training protocol featuring repetitive sinusoidal voltage cycling, we show that DIBs displaying memcapacitive properties can also exhibit persistent synaptic plasticity in the form of long-term potentiation (LTP) associated with capacitive energy storage in the phospholipid bilayer. The time scales for the physical changes associated with the LTP range between minutes and hours, and are substantially longer than previous STP studies, where stored energy dissipated after only a few seconds. STP behavior is the result of reversible changes in bilayer area and thickness. On the other hand, LTP is the result of additional molecular and structural changes to the zwitterionic lipid headgroups and the dielectric properties of the lipid bilayer that result from the buildup of an increasingly asymmetric charge distribution at the bilayer interfaces.
