The Medea hypothesis is the mirror of the Gaia hypotheis. Gaia says life is in ecological balance and self-balancing.
Part 1 of the Medea hypothesis says that life isnt necessarily in ecological balance and sometimes overruns resources nearly killing itself off. Several past mass extinctions, particularly the Permian may have been caused by this.
Part 2 says the ultimate end of life on Earth may be running out of CO2. CO2 has been falling from tens of percent on the early Earth to about one percent in the Phanerozoic to.025% now. (Human activity has temporarily raised it to.04%.) When CO2 falls below.01% then plants cannot survive and neither animals. Just bacteria. This is predicted in few hundred million years. Life consumes CO2 and buries in hydrocarbons and limestone. Unless some imbalance like humans come along, the trend is to pretty much lock up carbon for good.
Geo-engineering CO2 increase is straight forward. Burn limestone to release CO2. There is 100x more carbon in limestone than hydrocarbons.
Maybe words are localized to the parts of brain that control vocal muscles. (or gestures if you speak sign) Each word is a muscle pattern of how you speak it.
Or words are tied to the sensations and experiences they invoke. Or maybe words are combination of both muscle and sensual memory. This study could help reveal that.
Exceptional language like people who never speak but hear, or vice versa could have different brain patterns for words. Or they might have similar patterns because the brain recycles its architecture.
This is a current undetermined hypothesis. One evidence is how weak our memories are before were acquire language. My memories before age 3 are more flashes of sensation than systematic. Much of memory may require the scaffold of language.
There is planning, debugging, managing, maintaining, documenting, and selling it. Fresh-face kollege newbies think the percentage is the other way around. If you are lucky your company will offload some of these tasks to specialists, allowing you up to half your time coding.
My current company is conglomerate of about 40 startups around a special vertical theme (energy). The startup phase is a lot about writing code. Its only a minority activity here. But then I dont have to travel to Abu Dhabi to sell or manage my code then, which is often the beyond the capability of a startup.
Would this be the start of self-reproducing robots? A major problem is printing certain types of materials like metals. But there some metal printers now according to IEEE Spectrum. They print with some powder that is post-annealed with a laser.
Billion dollar revenue products that redefine the company. Google has had about three: Search, Adwords, and Android. Apple has had about six: Apple-2 , Mac/laser-printer, iPod, iPhone, iPad. Apple had a drought in the 1990s that nearly killed it. MicroSoft has been mostly living in the past the last decade. Every has to continually innovate to avoid Kodakization.
The first & second south pole expeditions arrived exactly 100 years ago. But the third one was in 1956. The technology and motivations had improved by then.
The Russian Lunokhod explored the moon for five lunar days in 1973. It those days it was driven in real being a little more than a light second from Earth.
Although Apple didnt invent this category of devices, they figured out how to make and sell tons of them in the last five years. Hardware innovation is very much alive in the USA.
Paul Krugman correctly points out in today NY Times column that Apple has 45,000 high compensated US employees and 700,000 poorly compensated Asian sub-contractors. Apple does create lots of jobs, with mixed results.
MIT prof Peter Hagelstein made one in the 1980s while working for energy labs. This fell into the class of "3rd generation nuclear weapons" which included very customized radiation outputs. And this excited Teller and Reagan into the "Star Wars" defense shield program. I dont think that program is dead yet, but highly morphed.
Its rather amazing to see the glaring headline "Retraction" in the letters section of these distinguished journals on a regular basis now. A dozen major scientists have written Science asking to retract the arsenic life paper. The policy is for authors to request retraction unless its a really extreme case like the XMRV retraction a few weeks ago (principal investigator in jail and authors suing each other). Most authors are honest and sometimes realize they've rushed to print without reproducible results. Then they'll retract.
I dont think there is anything horribly wrong with this process. Labs do rush to print for fame and priority. Readers want to see the newest results. There are many more papers now than decades ago. Reviewers dont have time to replicate the results during the review span of time and have to use their best judgment. Mistakes happen and are corrected. This is merely how good science works.
I see a couple every show advocating some high tech or fancy design. It is challenging to come up with enough capital to put these into production even on a custom basis. Telsa had dot-com billionaire seed money, alliances with established companies and a successful IPO.
The Edison Project was private for-profit K12 schools combining modern business management and high technology. Possibly a good idea, but got little traction. The wiki site said it was had to get the "education establishment" to buy in and build many of these.
Around where I am now there is a flourishing charter school ecology. Some are to escape the low-expectation public schools. Others have religious slant. And still others advocate challenging education like Chinese language immersion or computers. Even the high end schools worry some parents whether these are too fringe for their kids to get into a top college.
They might be able to start softball team of convicted inside traders at Fed Med by the end of the decade. its something everyone knows is happening, but almost no one gets caught.
In the "old days" these would take much longer than the integration calculations. by using a trig-identity you compute the new ones from power of two of the old ones using simple math. Or these days with large core memories you can pre-tabulate them, if you reuse the same lengths over and over.
In fact I have a hard time thinking of examples. People start running for office in their 30s and 40s. The PC founding generation is beyond that age group. The web creation generation is approaching that age.
Perhaps its because politics is mostly extroversion and most nerds are not like that.
A few scientific societies encourage some members to participate in governmental affairs. The American Association for the Advancement of Science and American Institute of Physics (both umbrella societies) are two cases. However the number of STEM PhDs or medical doctors in congress is very small.
If you define "tv" as screen time among all the gadgets we use in our life and work. Some people spend 80% of their conscious time staring at a screen of some kind from a cell to desktop to television. Younger people put their boomer elders to shame in this respect.
They ran a piece last summer tracking down a 1940s drone. It had a new-fangled invention called a TV camera that weighed 100 pounds at that time. The operator had to be in line-of-sight.

Here. And the data is already in numerical form.

One might claim since so much of web commercial activity is trans-border, only the feds can pass this type of law.

According to another news site. Maybe the Paul's want to be confrontational.

Resigned after 9 years. Sold all his stock. Apple III had failed. Mac was fine, but the board wanted an "adult" in charge. Steve returned in 12 years.
Mars is mostly CO2 and argon measured from Viking landerss. This is pretty distinctive for the solar system.
The Rio Grande rift is a classic extensional (expanding) zone. Downdrop valleys and volcanics.
It took several decades to get the primary controls right. Remember those silent film jokes about the starting cranking wacking you in the the butt?
