Developers cite concerns over fake news proliferation and risk of online impersonation

Groundbreaking new artificial intelligence text generation software built by a company backed by Elon Musk is too dangerous to make public, its creators say.

OpenAI, a nonprofit artificial intelligence research group, said their GPT-2 software is so good they are worried it could be misused.

The software generates coherent text, and can be prompted to write on certain subjects or in a certain style by feeding it paragraphs of source material.

The algorithm was trained on eight million web pages and the results are far better than any previous attempt at computer text-generation, where odd syntax changes and rambling nonsense have been difficult to iron out.

People often say that our genome is like a language. For example, a recent science paper explains that "genomes appear similar to natural language texts, and protein domains can be treated as analogs of words."¹

For that reason, DNA can be used to encode messages:

If just encoding text, one way is to convert each letter of the alphabet into a three-letter code. Using three bases, such as A, C, and T, gives 27 combinations - enough for the English alphabet plus a space - with a code such as AAA = A, AAC = B, and so on (1 in graphic below). However, researchers often want to encode more than just text, so most current methods instead first translate data into binary code - the language of 1s and 0s used in electronic media. Using binary, the four bases of DNA could theoretically store up to two bits of information per nucleotide, with a code such as A = 00, C = 01, and so on. --CATHERINE OFFORD, "INFOGRAPHIC: WRITING WITH DNA" AT THE SCIENTIST

In 2017, one Harvard group encoded a video, an image of one of the earliest surviving motion pictures, in a DNA sample from bacteria:
But in some ways, our genomes are much more powerful than words. They are part of a process that utters not just ideas but living beings. Including human beings, who ourselves have ideas.

After 15 years, the polling firm changed the way the question was asked: "Half of the respondents were asked about evolution in a two-step process much like the one described above. The other half of respondents were asked a single question about their views on evolution and given three response options" The graphic is pretty self-explanatory.
The pollster wanted to avoid forcing people to choose between science and religion:

The results of the new experiment indicate that there are some people who do believe that humans have evolved over time, but who, for whatever reason, did not say so in our traditional method of asking about the topic. Perhaps without the opportunity to immediately connect evolution to God, some religious respondents may be concerned that expressing belief in evolution places them uncomfortably on the secular side of a cultural divide.

The 19th century saw a wave of theories claiming to provide the answers for everything: Marxism, psychoanalytic theory, utilitarianism, Zionism, Darwinism, and more. But what did all their creators have in common, besides impressive beards? They all seemed to have a hollowed out, psychologically primitive understanding of human nature which denatured their own theories, and which has denatured the thought of all those influenced by their theories in the process.

Today on the Truth Perspective, we look at some of these theories, with an emphasis on Darwin, with reference to excerpts from Andrew Lobaczewski's writing on schizoid personality disorder and the creation and propagation of ideologies.

Russia is testing the heavy attack drone Okhotnik ('Hunter'), which is designed to dismantle an enemy's defenses. It is scheduled to enter service this year along with some similar models. Can it challenge the West's UAV reign?

The new heavy stealth attack drone Okhotnik will have its first test flight in the "nearest future," Industry and Trade Minister Denis Manturov said on Friday. The military earlier announced that it would start receiving new state-of-the-art recon and attack UAVs this year.

With the Pentagon extensively utilizing drones like MQ-1 Predator to spot and strike targets in places like the Middle East and Afghanistan, Moscow now hopes to up its game in drone warfare.

Scientific Breakthrough - Dolphin Sounds Generate Images

Research team discovers that dolphin sounds generate images with echolocation. Amplify your worldview and explore the science and technology behind the startling announcement of "what-the-dolphin-saw" sound images, by Jack Kassewitz and John Stuart Reid, from CymaScope.com.

This week the world was witness to a mind-bending scientific breakthrough: that the clicking sounds that dolphins transmit in using echolocation actually produce pictures that may be the basis of dolphin language. And further, that with specialized technology - that includes the use of a CymaScope and 3D print technology - researchers have seen what dolphins may be seeing for the first time. This could potentially lead to understanding dolphins and communication with dolphins in their own language. [1]

"We've been working on dolphin communication for more than a decade," stated Jack Kassewitz, research team leader and founder of SpeakDolphin.com where images and a press release are available. "When we discovered that dolphins not exposed to the echolocation experiment could identify objects from recorded dolphin sounds with 92% accuracy, we began to look for a way to see what was in those sounds." Kassewitz enlisted John Stuart Reid, inventor of the CymaScope, to search for sonic images in the dolphin recordings. [2]

Physicists used subatomic particles to probe the inner workings of a cloud

An invisible drizzle of subatomic particles has shown that thunderstorms may store up much higher electric voltages than we thought.

Using muons, heavier relatives of electrons that constantly rain down on Earth's surface, scientists probed the insides of a storm in southern India in December 2014. The cloud's electric potential - the amount of work necessary to move an electron from one part of the cloud to another - reached 1.3 billion volts, the researchers report in a study accepted in Physical Review Letters. That's 10 times the largest voltage previously found by using balloons to make similar measurements.

High voltages within clouds spark lightning. But despite the fact that thunderstorms regularly rage over our heads, "we really don't have a good handle on what's going on inside them," says physicist Joseph Dwyer of the University of New Hampshire in Durham who was not involved with the research.

Balloons and aircraft can monitor only part of a cloud at a time, making it difficult to get an accurate measurement of the whole thing. But muons zip right through, from top to bottom. "Muons that penetrate the thunderclouds are a perfect probe for measuring the electric potential," says physicist Sunil Gupta of the Tata Institute of Fundamental Research in Mumbai, India.

Last week Science unexpectedly published a scathing pre-publication review,¹ by Richard Lenski and two co-authors, of my book Darwin Devolves. I have already posted a short gleeful reply,² noting their almost complete lack of a response to the book's main argument, but I had planned to say more. This lengthier post will address such points as they do make, grouped into four themes: supposed counter-examples they cite; stale arguments they bring up; Lenski's own evolution work; and a clear conclusion to draw.

For readers who don't have time to plow all the way through, here are the take-home lessons:

• gene-level counter-examples cited by the reviewers are shamelessly question-begging; the reviewers simply gesture at genes and assume they were produced and/or integrated into living systems by random processes, but neither the reviewers nor anyone else has even tried to show that is possible;
• organ-level counter-examples cited by the reviewers as produced by exaptive processes are similarly question-begging;
• criticisms of my earlier books cited by the reviewers were similarly question-begging and/or relied on vague, imaginative stories;
• the reviewers are either unaware of or ignore my many detailed replies to earlier criticisms and to papers the reviewers themselves cite;
• as noted in my previous post, the reviewers don't even attempt to grapple with the main argument of the book, that beneficial degradative mutations will rapidly, relentlessly, unavoidably, outcompete beneficial constructive mutations at every time and population scale.

The idea that continents drift is now taken for granted, but it wasn't always. In fact, when the theory was proposed by Alfred Wegener in 1912, it was mocked, until decades later after Wegener had already died, when the theory was ultimately accepted. The issue was one of mechanism. Wegener couldn't adequately explain what was driving the continents apart. He did know that the evidence, including the way continents could be pictured as fitting together like pieces of a jigsaw puzzle, indicated strongly that they did so.

If this sounds familiar, it should. The debate about intelligent design is in many ways a replay of the controversy around Wegener's theory. Historian of science Michael Keas with the Center for Science & Culture notes the parallel in an illuminating conversation with Robert Crowther on ID the Future. The context is a discussion of methods for teaching about scientific controversies. Listen to the podcast here.

Most of us think of hydrogen peroxide as a sterilizing agent, normally found in disinfectants and mouthwash. It's not the first thing that comes to mind when discussing biology.

Yet, in a new paper published in the journal Astrobiology, Rowena Ball from the Australian National University and John Brindley from the University of Leeds in the U.K. suggest that this highly energetic and reactive compound may have played a critical role in the origin of life. Their "Hydrogen Peroxide (HP) Crucible Hypothesis" lays out the multiple ways the compound may have figured in the evolution of the first cell.

Hydrogen peroxide (H₂O₂) has two hydrogen and two oxygen atoms bound together. With twice the amount of oxygen as a molecule of water, it would have been a great source of chemical energy, and could have facilitated the prebiological evolution toward the RNA world-the stage in the development of life on Earth that many scientists believe to have existed before DNA and proteins appeared. (It also would have reacted with a lot of other compounds, however, that don't promote the evolutionary path toward RNA.)

The HP Crucible Hypothesis gets additional support from a recent paper by Greg Springsteen of Furman University in South Carolina and colleagues, who demonstrate that hydrogen peroxide can help generate a simple analog of the citric acid cycle-the most fundamental metabolic cycle for life on Earth. Significantly, this analog cycle works without the help of enzymes.
