Rover finds 2 new life clues on Mars | Space | EarthSky
<<To identify organic material in the Martian soil, Curiosity drilled into sedimentary rocks known as mudstone from four areas in Gale Crater. This mudstone gradually formed billions of years ago from silt that accumulated at the bottom of the ancient lake. The rock samples were analyzed by SAM, which uses an oven to heat the samples (in excess of 900 degrees Fahrenheit, or 500 degrees Celsius) to release organic molecules from the powdered rock. SAM measured small organic molecules that came off the mudstone sample – fragments of larger organic molecules that don’t vaporize easily. Some of these fragments contain sulfur, which could have helped preserve them in the same way sulfur is used to make car tires more durable, according to Eigenbrode. The results also indicate organic carbon concentrations on the order of 10 parts per million or more. This is close to the amount observed in Martian meteorites and about 100 times greater than prior detections of organic carbon on Mars’ surface. Some of the molecules identified include thiophenes, benzene, toluene, and small carbon chains, such as propane or butene. In 2013, SAM detected some organic molecules containing chlorine in rocks at the deepest point in the crater. This new discovery builds on the inventory of molecules detected in the ancient lake sediments on Mars and helps explains why they were preserved.>>

Alexa vs. Siri vs. Google: Which Can Carry on a Conversation Best? - The New York Times
<<As the devices that run these assistants become more commonplace — 39 million Americans now own one, according to a recent study — Amazon and competitors like Apple and Google foresee a day when you can chat with their assistants like you would with a friend. When you say something, one system tries to recognize each word and convert it to text. Another system tries to understand the meaning of each word and how it relates to the others. A third system spits out new text that responds to what you’ve said. A fourth converts this response to digital speech. Neural networks are complex mathematical systems that can learn particular tasks by pinpointing patterns in large amounts of data. They can learn to recognize spoken words, for instance, by analyzing recordings of old customer support calls. https://www.nytimes.com/interactive/2018/08/17/technology/alexa-siri-conversation.html #ai

New Trump power plant plan would release hundreds of millions of tons of CO2 into the air - The Washington Post
<<The plan, which is projected to release at least 12 times the amount of carbon dioxide into the atmosphere compared to the Obama rule over the next decade, comes as scientists have warned the world will experience increasingly dire climate impacts absent a major cut in carbon emissions. EPA estimates the measure will affect more than 300 U.S. plants, providing companies with an incentive to keep coal plants in operation rather than replacing them with cleaner natural gas or renewable energy projects. The power sector ranks as the second-biggest contributor to the nation’s overall greenhouse gas emissions, according to EPA, accounting for 28.4 percent of the total in 2016. Transportation made up 28.5 percent of U.S. greenhouse gas emissions that year. “They show not merely indifference to climate change, but really, opposition to doing anything about climate change.” “This is the latest in the Trump administration’s effort to make coal great again,” ...>> https://ift.tt/2MnZVHC #green

Somewhere Richard Nixon may be looking up and smiling. But aboveground, the special counsel is taking notes. “Decisions on security clearances should be based on national security concerns and not political views,”... The president essentially has accused Mr. Brennan of lèse majesté — the crime of criticizing the monarch, tantamount to treason. Remarkably, this relic of the days when kings were deemed divine remains on the books in some European monarchies as well as nations like Saudi Arabia, where a critique of the crown is considered terrorism. It’s not a crime in the United States. That’s why we fought a revolution against a mad king. They are sending a message to active-duty generals and admirals, soldiers and spies. Remember your oath to protect and defend the Constitution against all enemies, foreign and domestic. Think twice before following this man’s orders in a crisis.

In some cases, ex-officials retain their clearances and are called on to provide advice or input on classified or highly sensitive matters, experts said. Some ex-officials also have jobs that require a security clearance. “An enemies list is ugly, undemocratic and un-American.

Elizabeth Warren’s Accountable Capitalism Act, explained - Vox
<<“corporations sought to succeed in the marketplace, but they also recognized their obligations to employees, customers and the community.” In recent decades they stopped, in favor of a singular devotion to enriching shareholders. The conceit tying together Warren’s ideas is that if corporations are going to have the legal rights of persons, they should be expected to act like decent citizens who uphold their fair share of the social contract and not act like sociopaths whose sole obligation is profitability — as is currently conventional in American business thinking. Warren wants to create an Office of United States Corporations inside the Department of Commerce and require any corporation with revenue over $1 billion — only a few thousand companies, but a large share of overall employment and economic activity — to obtain a federal charter of corporate citizenship. Business executives, like everyone else, want to have good reputations and be regarded as good people but, when pressed about topics of social concern, frequently fall back on the idea that their first obligation is to do what’s right for shareholders. A new charter would remove that crutch, and leave executives accountable as human beings for the rights and wrongs of their own decisions. ... polluting companies invest heavily in making sure that regulators underregulate — and it seems to follow from the doctrine of shareholder supremacy that if lobbying to create bad laws is profitable for shareholders, corporate executives are required to do it. ... 80 percent of the value of the stock market is owned by about 10 percent of the population and half of Americans own no stock at all, this has been a huge triumph for the rich. Investment, however, has not soared. In fact, it’s stagnated. And a range of scholars believe shareholder capitalism is to blame. ... Warren view is that fundamentally, shareholder supremacy is a cause of poor economic performance by starving the business sector of funds that would otherwise be used to invest in equipment or training or simply to pay people more and increase their purchasing power. ... under the American system of shareholder supremacy, an executive increases his pay by finding ways to squeeze workers as hard as possible — kicking out the surplus to shareholders and then watching his stock-linked compensation soar. That’s brought America to the point where CEOs make more than 300 times as much as rank-and-file workers at big companies.>>

¿Sirven para algo el carbón activado y los multivitáminicos? Los falsos remedios del bienestar | Alimentos, Bacterias, Cáncer, Ciencia, Felicidad
<<... la moda de agregar una pizca de carbón activado a tus alimentos y bebidas. Se vende como un supuesto "desintoxicante". Adivina qué. Tiene la misma eficacia que un hechizo de la bruja de tu barrio. Desde siempre la medicina y la religión han estado profundamente relacionadas y hace muy poco tiempo que se separaron. El complejo industrial del bienestar busca revivir esa conexión. (solo algunas vitaminas han demostrado tener beneficios médicos, como el ácido fólico, antes y durante el embarazo, y la vitamina D, para los adultos mayores con riesgo de sufrir caídas) La orina color amarillo fluorescente derivada de los multivitamínicos podría darnos una sensación falsa de eficacia, pero es un engaño (y la consecuencia del exceso de vitamina B2 que nuestro cuerpo no pudo absorber). Observa con más atención la mayoría de los sitios de bienestar y de sus socios de la industria médica y descubrirás una plétora de teorías conspirativas: las vacunas y el autismo; los peligros de la fluoración del agua; los soutienes y el cáncer de mama; los celulares y el cáncer cerebral; el sida como un invento de la industria farmacéutica. Todos confundimos la repetición con la veracidad, un fenómeno llamado efecto de realidad ilusoria, y el conocimiento acerca del tema no te protege necesariamente. El hecho de que te expongas aunque sea una vez a información que suena plausible puede aumentar la percepción de veracidad. La enfermedad médica también es atemorizante. ¿A quién no le gustaría recibir vitaminas vía intravenosa en lugar de quimioterapia?>> #health

Trump’s proposed Space Force could worsen Earth’s orbital debris problem - The Washington Post
<<More than 170 million pieces of space debris — including decades-old satellites or spent rockets — already orbit the Earth today, with 29,000 of them being bigger than four inches. According to the European Space Agency, a satellite colliding with one of the 29,000 larger objects would be “catastrophic,” while smaller fragments could still penetrate surfaces. That’s one reason why nations long agreed to treat space as a largely demilitarized region. A space arms raise would inevitably increase the likelihood of a debris disaster... Debris doesn’t simply disappear as it circles Earth. Instead, it collides with other objects — splitting up into even more, smaller parts that can cut into satellites faster than speeding bullets. Humans appear well on track to turn the Earth’s lower orbit into a satellite kill zone even before any of their Space Forces have actually taken off.>>

<<Social media platforms regularly try to frame themselves as apolitical, at least in the sense of US politics, but it’s not that simple. Each platform comes with its own rules and Terms of Service.

Twitter is not Facebook any more than the United States is Canada. Just as countries are their governing documents, so are companies in relation to their Terms of Service. Twitter’s problem is that it’s never really stuck to a guide or agreed on how to enforce it. ... Reading through the rules as they’re laid out on the company’s website, it feels as though those documents are less actual guidelines of governance and more just a collection of vague ideas held together with masking tape and chewing gum. Twitter continues to struggle with its own identity. Facebook has more or less embraced its role as an info-hungry, hyper-capitalist surveillance state of a company (at nearly 4,200 words, Facebook’s section on data collection is nearly as long as the original US Constitution), YouTube has become an incubator for young conservative radicals, and Reddit and 4chan tend to embody digital anarchy. >>

It’s an invitation for a foreign power to help pick our elected leaders, a constitutional abomination and a repudiation of the very concept of democracy (i.e., we pick our own leaders).>>

Patients are desperate to resemble their doctored selfies. Plastic surgeons alarmed by ‘Snapchat dysmorphia.’
<<Doctors have spotted a trend of people bringing in their own selfies, usually edited with a smartphone application, and asking to look more like their photos. obsessive-compulsive spectrum.�“This is an alarming trend because those filtered selfies often present an unattainable look and are blurring the line of reality and fantasy for these patients,”... them as typical or average.”�Engeln described people who spend too much time worrying about their appearance as “beauty sick.” �“When you are beauty sick, you cannot engage with the world,” she said, “because between you and the world is a mirror. It’s a mirror that travels with you everywhere. You can’t seem to put it down.” Today’s generation can’t escape ‘the Truman effect’ because from birth they are born into an age of social platforms where their feelings of self-worth can be based purely on the number of likes and followers that they have, which is linked to how good they look or how great these images are,” .,, According to the annual American Academy of Facial Plastic and Reconstructive Surgery survey, selfies continue to be a driving force behind why people wish to get plastic surgery done. ... looking at a photo of yourself and not seeing the same thing reflected in the mirror or an unedited photo can make people unhappy. In some cases, it can even lead to developing body dysmorphic disorder A 2007 study published in Primary Psychiatry found that about 80 percent of people suffering from body dysmorphic disorder “experience lifetime suicidal ideation and 24% to 28% have attempted suicide.”>>

The State of Cryptocurrency Mining
<<... For basic hardware development, most algorithms can see substantial optimization just by taking away all of that generality and focusing on one specific thing. The vast majority of ASIC-resistant algorithms were designed by software engineers making assumptions about the limitations of custom hardware. These assumptions tend to be incorrect. At the end of the day, you will always be able to create custom hardware that can outperform general purpose hardware. For any algorithm, there will always be a path that custom hardware engineers can take to beat out general purpose hardware. It’s a fundamental limitation of general purpose hardware. A lot of people believe that computing is broken up into 3 categories: CPU, GPU, and ASIC. While those are the categories that are generally visible to the public, in the chip world there’s really only one type of chip: an ASIC. >> https://ift.tt/2GaNDu7 #btc

Why Big Tech's Fight Against InfoWars Is Unwinnable
<<The question was never really whether Jones had violated Facebook's policies---or YouTube's, for that matter---but whether the companies would ever fully enforce those policies at the risk of breaking their promise of radical openness. It was their own mythology about being neutral, coupled with the opacity of their algorithms and moderation practices, that enabled people like Jones—and more than a few Republican members of Congress—to baselessly accuse the companies of secret censorship in the first place. Now that they actually have restricted Jones' access, Facebook and YouTube have only given him more fodder to back up that particular conspiracy theory.>> Why Big Tech's Fight Against InfoWars Is Unwinnable - WIRED

Wendy Suzuki: The brain-changing benefits of exercise | TED Talk
<<...exercise actually changes the brain's anatomy, physiology and function. the most common finding in neuroscience studies, looking at effects of long-term exercise, is improved attention function dependent on your prefrontal cortex. You not only get better focus and attention, but the volume of the hippocampus increases as well. And finally, you not only get immediate effects of mood with exercise but those last for a long time. So you get long-lasting increases in those good mood neurotransmitters. ...the prefrontal cortex and the hippocampus are the two areas that are most susceptible to neurodegenerative diseases and normal cognitive decline in aging. So with increased exercise over your lifetime, you're not going to cure dementia or Alzheimer's disease, but what you're going to do is you're going to create the strongest, biggest hippocampus and prefrontal cortex so it takes longer for these diseases to actually have an effect.>>

ASIC Resistance is Nothing but a Blockchain Buzzword
Hashing is the act of scrambling data. You take anything you want, put it into a box, and out comes random 0’s and 1’s. There’s a few functions this provides, but generally it let’s you keep the input a secret while sharing the output. Hashing algorithms are a specific set of instructions used to generate a hash.

Some other algorithms use multiple parts of the CPU, some of which may be more costly to create specific hardware for, but again this falls short in the end. The only real purpose of these is to say “they don’t make ASICS for these” so you can feel fine using your computer at home. That’s great and all…until your coin starts becoming valuable and a company does decide to make dedicated hardware. Litecoin tried this, and now they have specialized mining hardware.

You can see these scams are multi-faceted, in that they use a “CPU only” algorithm as a one of many selling points to get people interested, but they then go and pre/insta-mine millions of coins without having to worry about competition before releasing it to everyone else.

... the amount of coins in existence doubled over the last year alone.

While I don’t think altcoins will disappear entirely anytime soon, the outlook for most of them medium-term is grim.

... the importance of having a low barrier-to-entry into the mining market, particularly in the “end game” scenario where a blockchain has become massively adopted. Ultimately this is the only thing that matters, because what’s the point in creating a temporarily semi-useful blockchain with no positive outlook to its future because only a few select entities can create the required hardware?

... renewable energy additions were 40 times the amount of energy Bitcoin mining used in the same year. We’re going to be in such a surplus of energy that latency (transporting it) will become the bottleneck for energy demand growth. Do you think these power companies are going to standby and just let all the extra energy production go to waste? They’re going to be producing clean energy at rates faster than they can export it, so where do you think all of that is going to eventually go?

Simple hardware designs that many manufacturers can produce, and mining facilities can be reasonably spread out among the globe wherever it’s convenient to use renewable energy sources.

This kind of necessary diversity/distribution/decentralization in hardware production is promoted by a Proof-of-Work algorithm that is the opposite of complicated, the opposite of resistant, and not prone to getting changed.

Bitcoin’s security is not dependent on our ability to hard-fork the PoW, and its security only grows as more hashpower comes online.

Unless Bitcoin’s immediate & obvious death is the only alternative, hard-forks are likely to always be contestable, and as such will always lack consensus.>

<<1. Hardware specialization resistance is futile. 2. The “success” of altcoins are not reliant on resistance. 3. Proof-of-Work algorithms need to be easy to manufacture. New altcoins are swimming upstream and must apply 1, 2, and 3. Changing a coins Proof-of-Work does nothing for it long term. Mining will be running on 100% clean energy in the future. Bitcoin mining is not ideally decentralized yet, but it’s certainly improving. Hard-forks require predominant consensus, if not impending doom. Bitcoin will never change its PoW unless a life threatening vulnerability is found, because the current PoW works.>>

Daniel Levitin: How to stay calm when you know you'll be stressed | TED Talk
<< ...the doctor says, "You know, I'd like to give you a drug that will help you lower your cholesterol, a statin." ...what this NNT (number needed to treat)? It's the number of people that need to take a drug or undergo a surgery or any medical procedure before one person is helped. And you're thinking, what kind of crazy statistic is that? The number should be one. My doctor wouldn't prescribe something to me if it's not going to help. But actually, medical practice doesn't work that way. ...GlaxoSmithKline estimates that 90 percent of the drugs work in only 30 to 50 percent of the people. So the number needed to treat for the most widely prescribed statin, what do you suppose it is? How many people have to take it before one person is helped? 300. ... for this particular drug, the side effects occur in five percent of the patients. And they include terrible things -- debilitating muscle and joint pain, gastrointestinal distress ...300 people take the drug, right? One person's helped, five percent of those 300 have side effects, that's 15 people. You're 15 times more likely to be harmed by the drug than you are to be helped by the drug. For the most widely performed surgery on men over the age of 50, removal of the prostate for cancer, the number needed to treat is 49. That's right, 49 surgeries are done for every one person who's helped. And the side effects in that case occur in 50 percent of the patients. They include impotence, erectile dysfunction, urinary incontinence, rectal tearing, fecal incontinence. And if you're lucky, and you're one of the 50 percent who has these, they'll only last for a year or two.>> https://ift.tt/1WomxB4 #health #cholesterol

20 Years of Wisdom From Amazon's Jeff Bezos -- The Motley Fool
<<Because of our emphasis on the long term, we may make decisions and weigh trade-offs differently than some companies. ... We will continue to make investment decisions in light of long-term market leadership ... rather than short-term ... Wall Street reactions. Owners are different from tenants. I know of a couple who rented out their house, and the family who moved in nailed their Christmas tree to the hardwood floors instead of using a tree stand. ... No owner would be so short-sighted. Similarly, many investors are effectively short-term tenants, turning their portfolios so quickly they are really just renting the stocks that they temporarily "own." Failure comes part and parcel with invention. It's not optional. We understand that and believe in failing early and iterating until we get it right. When this process works, it means our failures are relatively small in size (most experiments can start small), and when we hit on something that is really working for customers, we double-down on it with hopes to turn it into an even bigger success.>> https://ift.tt/2MmibNt #bezos #amazon

Un negocio de 340 millones de euros - Fútbol - Ovación - Últimas noticias de Uruguay y el Mundo actualizadas - Diario EL PAIS Uruguay
<<El campeón italiano todavía está lejos del poder comercial de Manchester United, Barcelona. Real Madrid y Bayern Munich. Por el auspicio de su camiseta, Juventus recibe 17 millones de la marca Jeep y 23 millones de Adidas. En cambio, el valor de la camiseta del Manchester es de 156 millones, la del Barcelona 140 y la del Real Madrid 95. ... Uno de los aspectos que Juventus espera aprovechar es la extraordinaria presencia de Cristiano Ronaldo en las redes sociales. KPMG recuerda que con 332 millones de seguidores entre Facebook, Instagram y Twitter, “la estrella portuguesa es la personalidad más seguida en el mundo y disfruta de una base de fanáticos masiva a nivel mundial”. Juventus, en tanto, tiene “solo” 55 millones de seguidores. La exposición de CR7 en Asia, América del Sur y Central, así como Estados Unidos, ayudaría al club a crear una marca global que, a su vez, resultaría en mayores ingresos. Hoy, la distribución geográfica de los seguidores de la Juve en las redes es muy diferente a la de su nueva estrella.>>

El día del exceso: desde el 1º de agosto el mundo consume más recursos de los que tiene | Agua, Residuos, tierra, Trending Topic, Uruguay
<<La biocapacidad global promedio es de 1.7 hectáreas globales por persona, o sea que se precisan 1.7 hectáreas para proporcionar, absorber y regenerar los recursos que una persona consume en su vida. La huella ecológica de Suiza por ejemplo es 4.85 gha por persona, lo que significa que si toda la humanidad consumiera como Suiza se precisarían 2.9 Planetas (4.85/1.7). Si miramos la región la cantidad de planetas necesarios igual es alarmante: Argentina precisaría 2.2 planetas y Chile 2.4. Uruguay no escapa a esta realidad, tiene una huella ecológica de 3.0 gha. Si la humanidad consumiera con los niveles uruguayos precisaríamos prácticamente dos (1.8) planetas. El Overshoot day para Uruguay fue el 25 de julio.>>
