Are Hawaiian Monk Seals Natural? Not According to Some Hawaiians

Like pandas, Hawaiian monk seals are loved by many for their cute, cuddly appearance. And like pandas, the species is close to becoming extinct. With only 1,100 Hawaiian monk seals left in the world, scientists predict the seal is going to disappear in 50 to 100 years. Their extinction is only being accelerated by a spate of mysterious killings. According to a fascinating detective story over at the New York Times Magazine:

“Many in Hawaii were convinced that the entire history of the monk seal is based on a lie. Because the species was eradicated in the mains so long ago, people have lived on Kauai their entire lives without seeing a single monk seal until recently. Traditional Hawaiian knowledge carries great authority on the islands, and in every cranny of the culture where you’d expect to see monk seals, people saw none […] The logical explanation, for many, was that the seal wasn’t actually native to Hawaii, that the government had brought the animals, in secret, to create jobs for scientists and push its environmentalist agenda…”.

Engineering Beneficial Parasites

Toxoplasma gondii is a parasite that causes rats to become less afraid of cats. It also might change the behavior of humans, making women more outgoing and warmhearted, while men get jealous and suspicious. Toxoplasma gondii is shed in cat feces, which get eaten by rats. Infected rats become fearless to cats and then get caught easily, thus completing the parasite’s cycle through its different hosts. If a parasite can make you feel friendly, what other unusual benefits might they have?

The Holy Grail of Immortality

The biggest fight we have as an organism is life itself. Continuously resupplying our body with nutrients and energy takes its toll. Our cells that are constantly working, dying and dividing as we go through our life provide us with the means to live. However, these systems inevitably break down. Is this the way things have to be?

Yes, Naturally

The following essay is from Yes Naturally: How Art Saves the World available in the Next Nature store. You can visit the Yes Naturally exhibit in the The Hague until August 18. 

What is nature? And who or what has a say in this? Are human beings the only ones who decide, or do plants, animals, bacteria, atmospheres, things and computers play a role as well? Yes Naturally puts anthropocentrism – centralizing the human position above all or interpreting reality exclusively in terms of human standards – in perspective. Is our arrogant placing of ourselves above all other agents in the world really justified? Is the DNA of a multicellular organism such as ourselves really so different from that of a virus? Our digestive tract looks remarkably like that of a sea squirt, which belongs to the most primitive of tunicates that have been around for more than 500 million years. And we have more in common with plants than we may on the surface suspect. Mitochondria are the energy producers of plants and animals: they are offspring of bacteria that lived in intracellular symbiosis with their hosts in an early evolutionary stage. Interconnectedness and interdependence are in fact the measure of all things.

genetically modified sheep

Modifying Milk and Glowing Livestock

A team of scientists from the Animal Reproduction Institute of Uruguay have genetically modified nine sheep with a phosphorescent jellyfish protein. This causes the lambs to grow a neon green colour when exposed to ultraviolet light. Besides the lambs’ predisposition to glow green, they are otherwise perfectly healthy and normal.

Genetically modifying the sheep to glow under UV light is an attempt to advance and perfect the technique that will allow scientists to add beneficial new genes to livestock. Once the genes are integrated into an animal’s DNA, it can produce milk with various medical advantages for humans. Perhaps this could lead to the creation of a real-life Korova Milk Bar, the bar from “A Clockwork Orange” that offers drug-laced milk.

The Prefuture of Synthetic Biology

Somewhere between a vat of expensive face cream and a baby Neanderthal lies a probable future for synthetic biology. While synbio start-ups – large and small – struggle with the reality of scaling up microscopic cellular factories into profitable business models, stories of DIY anti-cancer research, Neanderthal cloning, limitless ‘green’ kerosene, and tumor-killing bacteria are told as outcomes of a likely future where humans have full control over biology.

Over the last decade, many diverse interests have contributed to this ambition of an easy-to-manipulate biology, as the field of synthetic biology has spread around research labs all over the world. Scientists, engineers, policymakers, industrialists, space agencies, politicians, and even designers are constructing a future defined by the grand rhetoric of a world-changing, world-saving technology.

Electric Skin Could Allow Robots to Feel

There are plenty of robot arms out there, but what about the skin to cover them in? A new kind of piezotronic transistor mesh could make for robotic skin that’s as sensitive as your own is, covered in thousands of tiny mechanical hairs.

The inventor of the technology, Zhong Lin Wan from Georgia Tech, says it has immediate applications in human-machine interfaces. It could for example be used to capture electronic signatures by recording the distinctive force an individual applies while signing. In due time, Wan expects the pressure sensor arrays could equip robotics and prosthetics with a human-like sense of touch.
