# trade: job career quick transitions, from Silicon Valley to the Cannabis Marketplace

<< For decades, those looking to change the world arrived in Silicon Valley seeking the latest frontier: social media companies, gadget makers, delivery and transportation apps, e-commerce platforms. >>

<< But as the emerging markets of yesterday become today's stalwarts, a growing number of technology workers are migrating to an even newer sector-so new that it isn't legal at the federal level. >>

<<  The U.S. cannabis market is expected to grow to $75 billion in sales by 2030 from $10 billion, said Troy Dayton, chief executive of cannabis investment and market research firm Arcview. >>

<< Eaze, which aspires to be something of an Amazon for pot, has raised more than $50 million from tech investors such as DCM and Fresh VC. PAX Labs, whose cannabis vaporizers resemble Apple gadgets, has raised more than $100 million from Silicon Valley and institutional investors. And Baker Technologies, which is essentially a Salesforce for dispensaries, made it into 500 Startups' prestigious accelerator program in 2015. >>

# behav: social isolation vs. evolutionary dynamics

<< For some animals—such as beetles, ants, toads, and primates—short-term social isolation can be just as vital as social interaction to development and long-term evolution. In a review published July 17 in the journal Trends in Ecology & Evolution, two evolutionary biologists describe approaches for testing how an animal's isolation might impact natural selection and evolution. >>

Social isolation: Animals that break away from the pack can influence evolution. Cell Press. Jul 17, 2018.

AA << suggest that the 'index of social isolation', the mismatch between actual and optimal social interaction experienced by individuals within a population, may play a key role in releasing cryptic genetic variation, adaptation rates, diversification patterns, and ecosystem-level processes. Evolutionary dynamics arising from social isolation could have significant impacts in applied settings such as conservation, animal breeding, control of biological invasions, and evolutionary resilience to anthropogenic change. >>

# acad: oops! when a big research (MACH15 clinical study, funded by several million dollars) can go wrong

<< The National Institutes of Health plans to end funding to the Moderate Alcohol and Cardiovascular Health (MACH) trial. The decision is based on concerns about the study design that cast doubt on its ultimate credibility.  >>

NIH to end funding for Moderate Alcohol and Cardiovascular Health trial. Jun 15, 2018.   

<< last month, the National Institutes of Health took the unusual step of shutting down one of its own clinical trials - a $100 million dollar experiment gone wrong. The announcement followed an internal investigation, prompted by a dogged New York Times report, that uncovered inappropriate interactions between the alcohol industry (Anheuser-Busch InBev, Heineken, and others) and the NIAAA in the execution of MACH15. >>

# astro: after Florence, the binary nature of the near-Earth asteroid 2017 YE5, as dark as charcoal.

<< Near-Earth asteroid 2017 YE5 was discovered with observations provided by the Morocco Oukaimeden Sky Survey on Dec. 21, 2017. >>

<< On June 24 (..) they were able to confirm that 2017 YE5 consists of two separated objects. By June 26, both Goldstone and Arecibo had independently confirmed the asteroid's binary nature. >>

<< At its closest approach to Earth, the asteroid came to within 16 times the distance between Earth and the moon. >>

<< 2017 YE5 is likely as dark as charcoal. >>

<< Asteroid Florence, a large near-Earth asteroid, will pass safely by Earth on Sept. 1, 2017, at a distance of about 4.4 million miles, (7.0 million kilometers, or about 18 Earth-Moon distances). Florence is among the largest near-Earth asteroids that are several miles is size; measurements from NASA's Spitzer Space Telescope and NEOWISE mission indicate it's about 2.7 miles (4.4 kilometers) in size. >>

# gst: the 'memory' of a friction

<< Contrary to what you may have learned in high school, friction between two surfaces is not constant. For a wide range of materials and surface types, it increases with time, as microscopically uneven surfaces deform and come into closer contact. Experiments now find an additional wrinkle: friction can have a memory, meaning that it can depend not only on the current state of the interface but also on how it got there. The findings hint at connections between friction and the behavior of glasses and other disordered systems and, in the long run, may influence how scientists think about friction associated with earthquakes, industrial machinery, and micromachines. >>

# behav: compassionate ants

<< Open wounds are a major health risk in animals, with species prone to injuries likely developing means to reduce these risks. >>

AA << analysed the behavioural response towards open wounds on the social and individual level in the termite group-hunting ant Megaponera analis.  During termite raids, some ants get injured by termite soldiers (biting off extremities), after the fight injured ants get carried back to the nest by nest-mates. [AA] observed treatment of the injury by nest-mates inside the nest through intense allogrooming at the wound. Lack of treatment increased mortality from 10% to 80% within 24 h, most likely due to infections. >>

# ai-bot: actually, things could start to get out of control

<< It’s clear that companies have identified the value of bots and integrated them into their sales, customer service, and human resource processes. But now individuals are also starting to use them to navigate through the bot-heavy world of the internet, which leads to bot-bot interactions where humans are not involved anymore. >>

<<  If bots are now more efficient than people, they can get things done in a way humans can’t  - and we all know this. But when there’s also a bot on the other side, things start to get out of control. >>
