USEPA has approved a strain of genetically engineered oil producing algae to be tested outdoors.
On August 1, 2013, EPA received TSCA Experimental Release Applications (TERAs) R-13-0003, -0004, -0005, -0006 and -0007 from Sapphire Energy, Inc. to test five different intergeneric strains of the photosynthetic green algae Scenedesmus dimorphus in open ponds. The purpose of the field test is to (1) evaluate the translatability of the genetically modified strains from the laboratory to an outdoor setting, and (2) to characterize the potential ecological impact (dispersion and invasion) of the genetically-modified microalgae. The introduced intergeneric DNA sequences include certain metabolism genes and an intergeneric marker gene that enables detection of the microorganism from environmental samples. Also, different regulatory elements controlling expression of the genes were used, resulting in the five intergeneric strains. The field trials are to be conducted at the University of California San Diego Biology Field Station (BFS) in La Jolla, CA.
On a crowded train platform, Interpol agent Kenneth Durand feels the sting of a needle—and his transformation begins…
In 2045 Kenneth Durand leads Interpol’s most effective team against genetic crime, hunting down black market labs that perform “vanity edits” on human embryos for a price. These illegal procedures augment embryos in ways that are rapidly accelerating human evolution—preying on human-trafficking victims to experiment and advance their technology.
With the worlds of genetic crime and human trafficking converging, Durand and his fellow Interpol agents discover that one figure looms behind it all: Marcus Demang Wyckes, leader of a powerful and sophisticated cartel known as the Huli jing.
But the Huli jing have identified Durand, too. After being forcibly dosed with a radical new change agent, Durand wakes from a coma weeks later to find he’s been genetically transformed into someone else—his most wanted suspect: Wyckes.
Now a fugitive, pursued through the genetic underworld by his former colleagues and the police, Durand is determined to restore his original DNA by locating the source of the mysterious—and highly valuable—change agent. But Durand hasn’t anticipated just how difficult locating his enemy will be. With the technology to genetically edit the living, Wyckes and his Huli jing could be anyone and everyone—and they have plans to undermine identity itself.
La Paz, Bolivia, is in a serious crisis caused by loss of its glacier-fed water supply. At the same time we are losing glaciers and snowpack in important food-growing regions, the global groundwater situation is also looking bleak. And for those of us trying to do our little part for water conservation, investing in a residential graywater system can take around 15 years to break even at current costs and water rates.
Trump admires Andrew Jackson, who I consider a genocidal lunatic and the worst President in U.S. history.
Fluoridated drinking water could eventually be looked back on as a really stupid idea that damaged several generations of developing brains, like leaded gasoline. Or not…I’m not sure who to believe on the issue but caution is clearly warranted.
Most hopeful stories:
A new political survey says there is a chance that a majority of Americans are not bat-shit crazy. Which suggests they might not be too serious about Steve Bannon, who believes in some bat-shit crazy stuff. There are a number of apps and guides out there to help sane people pester our elected representatives when they fail to represent our interests.
South Korean women are projected to be the first to break the barrier of an average life expectancy of 90, with a 50% probability of this happening by 2030.
Advanced power strips can reduce the so-called “vampire loads” of our modern electronic devices that are never really off.
Most interesting stories, that were not particularly frightening or hopeful, or perhaps were a mixture of both:
This long NASA article first gets you excited about the possibility of life on eight new planets it has just discovered, and then throws cold water (actually, make that lethal X-rays) all over your excitement.
Bill Gates has proposed a “robot tax”. The basic idea is that if and when automation starts to increase productivity, you could tax the increase in profits and use the money to help any workers displaced by the automation. In related somewhat boring economic news, there are a variety of theories as to why a raise in the minimum wage does not appear to cause unemployment as classical economic theory would predict.
CRISPR could be used to create new crops out of the wild ancestors of our current crops.
The Doomsday Clock was moved to 2.5 minutes to midnight. The worst it has ever been was 2 minutes to midnight in the early 1980s. In related news, the idea of a U.S.-China war is looking a bit more plausible. The U.S. military may be considering sending ground troops to Syria.
Russian hackers are cheating slot machines by figuring out the pattern on pseudo-random numbers they generate.
From a new book called Homo Deus: “For the first time ever, more people die from eating too much than from eating too little; more people die from old age than from infectious diseases; and more people commit suicide than are killed by soldiers, terrorists and criminals put together. The average American is a thousand times more likely to die from binging at McDonalds than from being blown up by Al Qaeda.”
This article in Trends in Plant Science (which I know you’ve seen, since it flies off the news stands) argues that CRISPR should be used to create entirely new crops out of wild plants, mimicking the process that created our most common cereal crops over thousands of years.
Of the more than 300 000 plant species that exist, less than 200 are commercially important, and three species – rice, wheat, and maize – account for the major part of the plant-derived nutrients that humans consume.
Plants with desirable traits, such as perennials with extensive root systems and nitrogen-fixing plants, are currently being domesticated as new crops…
Several traits in crops that were crucial for their domestication are caused by mutations that can be reproduced by genome-editing techniques such as CRISPR/Cas9, offering the potential for accelerated domestication of new crops.
NPR had a review of this book recently (below is the Amazon description).
Homo Deus: A Brief History of Tomorrow
Yuval Noah Harari, author of the critically-acclaimed New York Times bestseller and international phenomenon Sapiens, returns with an equally original, compelling, and provocative book, turning his focus toward humanity’s future, and our quest to upgrade humans into gods.
Over the past century humankind has managed to do the impossible and rein in famine, plague, and war. This may seem hard to accept, but, as Harari explains in his trademark style—thorough, yet riveting—famine, plague and war have been transformed from incomprehensible and uncontrollable forces of nature into manageable challenges. For the first time ever, more people die from eating too much than from eating too little; more people die from old age than from infectious diseases; and more people commit suicide than are killed by soldiers, terrorists and criminals put together. The average American is a thousand times more likely to die from binging at McDonalds than from being blown up by Al Qaeda.
What then will replace famine, plague, and war at the top of the human agenda? As the self-made gods of planet earth, what destinies will we set ourselves, and which quests will we undertake? Homo Deus explores the projects, dreams and nightmares that will shape the twenty-first century—from overcoming death to creating artificial life. It asks the fundamental questions: Where do we go from here? And how will we protect this fragile world from our own destructive powers? This is the next stage of evolution. This is Homo Deus.
With the same insight and clarity that made Sapiens an international hit and a New York Times bestseller, Harari maps out our future.
This Wired article talks about tiny balls of mouse brain cells complete with blood vessels connected to a “microfluidic” chip that essentially acts as a heart.
In the last five years, researchers have engineered lots of dish-dwelling micro-organs, from itsy bitsy intestines to Lilliputian livers. They’ve simultaneously made major advances in biochips: small, Flash-drive-sized structures lined with a layer or two of cells and studded with biosensors and microfluidic channels. Those two-dimensional chips are useful for testing, say, how lung cells react to a piped-in toxin, but they’re too simplistic to truly mimic organs. That’s where organoids like Hoffman-Kim’s brain balls come in. For the first time, 2-D biochips are colliding with 3-D mini-organs—and together they’re making some of the best organ simulations ever.
Using these mashups, the idea is that scientists will be able to take a few of your skin cells, grow miniature versions of all your major organs, and put them on a chip. Then doctors can test out the best compounds for whatever disease you might have—not in a mouse, but in a mini-you. “This will enable a new era of personalized medicine,” says Ali Khademhosseini, a bioengineer at Harvard’s Wyss Institute who has been working on both mini-organs and biochips for the last decade.
In a paper that will be published later this month, Khademhosseini’s team created a series of chips connecting liver organoids and cancer cells with loops of tiny tubes. They pumped an anticancer drug through the system, tracking whether it killed the tumor cells and whether the liver cells could survive the toxic onslaught. That way, they could optimize a drug dosage that maxed cancer-killing power while keeping the liver out of harm’s way.
I can’t help wondering if these body-less mouse brains are sentient on some level, or if they could be. Do they have a natural life span, or can they regenerate and repair themselves indefinitely? Could someone create a human consciousness this way? If so, could it survive and develop in the absence of a body? Could it be plugged into a simulation so it thought it had a body? Could it be plugged into a spacecraft or a submarine and sent out to explore?
If you could bring back just one animal from the past, what would you choose? It can be anyone or anything from history, from the King of the Dinosaurs, T. rex, to the King of Rock ‘n’ Roll, Elvis Presley, and beyond.
De-extinction, the ability to bring extinct species back to life is fast becoming reality. Around the globe, scientists are trying to de-extinct all manner of animals, including the woolly mammoth, the passenger pigeon and a bizarre species of flatulent frog. But de-extinction is more than just bringing back the dead. It’s a science that can be used to save species, shape evolution and sculpt the future of life on our planet.
In Bring Back the King, scientist and comedy writer Helen Pilcher goes on a quest to identify the perfect de-extinction candidate. Along the way, she asks if Elvis could be recreated from the DNA inside a pickled wart, investigates whether it’s possible to raise a pet dodo, and considers the odds of a 21st century Neanderthal turning heads on public transport.
Pondering the practicalities and the point of de-extinction, Bring Back the King is a witty and wry exploration of what is bound to become one of the hottest topics in conservation if not in science as a whole in the years to come.
