The terrorist or psychopath of the future, however, will have not just the Internet or drones—called “slaughterbots” in this video from the Future of Life Institute—but also synthetic biology, nanotechnology, and advanced AI systems at their disposal. These tools make wreaking havoc across international borders trivial, which raises the question: Will emerging technologies make the state system obsolete? It’s hard to see why not. What justifies the existence of the state, English philosopher Thomas Hobbes argued, is a “social contract.” People give up certain freedoms in exchange for state-provided security, whereby the state acts as a neutral “referee” that can intervene when people get into disputes, punish people who steal and murder, and enforce contracts signed by parties with competing interests.

The trouble is that if anyone anywhere can attack anyone anywhere else, then states will become—and are becoming—unable to satisfy their primary duty as referee.

As the world’s most popular shoe, flip-flops account for a troubling percentage of plastic waste that ends up in landfills, on seashores and in our oceans. Scientists at the University of California San Diego have spent years working to resolve this problem, and now they have taken a step farther toward accomplishing this mission.

Sticking with their chemistry, the team of researchers formulated polyurethane foams, made from algae oil, to meet commercial specifications for midsole shoes and the foot-bed of flip-flops. The results of their study are published in Bioresource Technology Reports and describe the team’s successful development of these sustainable, consumer-ready and biodegradable materials.

The research was a collaboration between UC San Diego and startup company Algenesis Materials—a materials science and technology company. The project was co-led by graduate student Natasha Gunawan from the labs of professors Michael Burkart (Division of Physical Sciences) and Stephen Mayfield (Division of Biological Sciences), and by Marissa Tessman from Algenesis. It is the latest in a series of recent research publications that collectively, according to Burkart, offer a complete solution to the plastics problem—at least for polyurethanes.

In the first billion years, there was no oxygen on Earth. Life developed in an anoxic environment. Early bacteria probably obtained their energy by breaking down various substances by means of fermentation. However, there also seems to have been a kind of “oxygen-free respiration.” This was suggested by studies on primordial microbes that are still found in anoxic habitats today.

“We already saw ten years ago that there are genes in these microbes that perhaps encode for a primordial respiration enzyme. Since then, we—as well as other groups worldwide—have attempted to prove the existence of this respiratory enzyme and to isolate it. For a long time unsuccessfully because the complex was too fragile and fell apart at each attempt to isolate it from the membrane. We found the fragments, but were unable to piece them together again,” explains Professor Volker Müller from the Department of Molecular Microbiology and Bioenergetics at Goethe University.

Through hard work and perseverance, his doctoral researchers Martin Kuhns and Dragan Trifunovic then achieved a breakthrough in two successive doctoral theses. “In our desperation, we at some point took a heat-loving bacterium, Thermotoga maritima, which grows at temperatures between 60 and 90°C,” explains Trifunovic, who will shortly complete his doctorate. “Thermotoga also contains Rnf genes, and we hoped that the Rnf enzyme in this bacterium would be a bit more stable. Over the years, we then managed to develop a method for isolating the entire Rnf enzyme from the membrane of these bacteria.”

When baboons experience trauma in early life, they have higher levels of stress hormones in adulthood—a potential marker of poor health—than their peers who don’t experience trauma, even if they have strong social relationships as adults, according to a study led by a University of Michigan researcher.

The study examined the links between childhood adversity, adult social relationships and glucocorticoid concentrations. The goal was to determine whether one of the reasons that baboons who experience early trauma live shorter, less healthy lives was because they fail to develop strong social relationships in adulthood, which could be beneficial to health.

U-M biological anthropologist Stacy Rosenbaum and her co-authors found that while early life adversity didn’t strongly affect baboons’ ability to have social relationships, any positive effect of those relationships was much smaller than the large negative effects of early life trauma.

Imagine tiny crystals that “blink” like fireflies and can convert carbon dioxide, a key cause of climate change, into fuels.

A Rutgers-led team has created ultra-small titanium dioxide crystals that exhibit unusual “blinking” behavior and may help to produce methane and other fuels, according to a study in the journal Angewandte Chemie. The crystals, also known as nanoparticles, stay charged for a long time and could benefit efforts to develop quantum computers.

“Our findings are quite important and intriguing in a number of ways, and more research is needed to understand how these exotic crystals work and to fulfill their potential,” said senior author Tewodros (Teddy) Asefa, a professor in the Department of Chemistry and Chemical Biology in the School of Arts and Sciences at Rutgers University-New Brunswick. He’s also a professor in the Department of Chemical and Biochemical Engineering in the School of Engineering.

MetaRomantism and “Evil”

MetaRomanticism can be thought of as an attempt to reform Romanticism, which seems necessary since it seems to be a constant companion to Modernism and it is especially dangerous when it has access to Modernist tools that is uses while refusing to be rational. Perhaps this explains the horrors of Nazism in the 20th century. Nazis were irrationalist Romantics that stole the Modernist tools of Weimar Germany and nearly destroyed human civilization and they attached themselves to Dharma traditions that sometime support versions of annihilationism.

How can MetaRomanticism help?

Summary: Repetitive transcranial memory stimulation applied to the dorsolateral prefrontal cortex modifies the negative effects of fear memories. The findings could have implications for the treatment of PTSD.

Source: University of Bologna

A research group from the University of Bologna has succeeded in modifying the negative effect of a returning memory that triggers fear, and developed a new non-invasive experimental protocol. The result of this study, published in the journal Current Biology, is an innovative protocol that combines fear conditioning—a stimulus associated with something unpleasant that induces a negative memory—and the neurostimulation of a specific site of the prefrontal cortex.

A team of researchers led by Cunjiang Yu, Bill D. Cook Associate Professor of Mechanical Engineering at the University of Houston, has developed a new form of electronics known as “drawn-on-skin electronics,” allowing multifunctional sensors and circuits to be drawn on the skin with an ink pen.

The advance, the researchers report in Nature Communications, allows for the collection of more precise, motion artifact-free health data, solving the long-standing problem of collecting precise biological data through a wearable device when the subject is in motion.

The imprecision may not be important when your FitBit registers 4,000 steps instead of 4,200, but sensors designed to check heart function, temperature and other physical signals must be accurate if they are to be used for diagnostics and treatment.

The squid typically have dark eyes and an array of black and reddish brown spots across their bodies while the genetically altered hatchlings have light pink or red eyes and almost no dark spots.

The milestone, which was first reported in Current Biology Thursday, could pave the way for researchers to study the biology of cephalopods like squid, octopus and cuttlefish the same way they study more common lab animals like study mice and fruit flies.
