Copper has been in use by humans for about 10,000 years and without this incredible metal, society could not possibly be what it is today. With a vast amount of uses, copper is antimicrobial, corrosion-resistant, and a superior heat and electricity conductor that has revolutionized technology and our modern way of life.
Life evolved to live within limits. It's a delicate balance. Humans need oxygen, but too much can kill us. Plants need nitrogen, but excess nitrogen harms them, and pollutes rivers, lakes and oceans. Ecosystems are complex. Our health and survival depend on intricate interactions that ensure we get the right amounts of clean air, water, food from productive soils and energy from the sun.
The penultimate upgrade for humanity would be a perfect synthesis of human and machine -- superior to an entirely biological human, but possessing the same mind in this new hybridized frame. So what does this have to do with transgender people?
Biohacking is the practice of changing our biology and physical situation by employing the hacker ethic -- sharing, openness, decentralization, free access, and world improvement. It's the idea that we can be so much more than we are born with if we just added to our bodies and chemistry.
Just as human activity is harming the diversity of visible life, it's also diminishing microbial diversity. As researchers learn more about the profound ways good microbes keep people healthy, they're also seeing how our urbanized, indoor lifestyles have transformed our microbiomes, increasing the risk of disease.
I worry a lot about how we don't understand nature anymore. Now I'm not talking about the value of nature or the importance of conservation. That worries me too, but what I'm talking about is the basic understanding of the plants and animals that co-exist with us. I'll call this nature literacy.
Given predictable increases in population and demand, for meat production to take place responsibly in the future, we will have to significantly diversify our eating habits, and with them, our production habits. In vitro meat is one alternative. We don't know enough about it yet. But we know we can make it. It is possible.
The classic definition of a biological species is the ability to breed within its group, and the inability to breed outside it. A study published July 29 in the journal PLOS Biology offers some important clues about the evolution of barriers to breeding.
I'm tired of being ashamed of being an environmentalist. Why is the conversation of global warming, and water rights, so "boring"? Personally, I'd rather be perceived as a so-called "boring" environmentalist and communicate about the importance of water.
Unlike humans, who need on average 20 years between generations, these small creatures only need about 20 minutes to foster offspring. This means that the bacterium can evolve some 500,000 times faster than us. This rapid rate offers the prime opportunity to explore some of the deeper mysteries and perhaps even offer mechanisms to best predict when evolution might happen to us.
