Another way to get rid of diseases that predominately affect people living in poverty is to get people out of poverty.
Despite there being no cure for Ebola, there's an 82% survival rate for cases in the United States. In Africa, the survival rate is only 50%, and the disease spreads much more rapidly.
You'd be surprised how many diseases can be prevented with basic hygiene practices, and how many diseases can be treated with basic drugs.
Plumbers save more lives than doctors. Don't take them for granted.
Does the resulting object have desirable mechanical properties, or is it fragile and useless? Most people want to do something useful with their creations.
I don't care if the printer is slow if it can make an object out of Nylon with 30% glass fiber reinforcement. (or even better, Inconel!) That material has good mechanical properties.
Most of the solutions to the three-body problem (what happens when 3 arbitrary bodies bound by gravity are orbiting each other) result in two of the bodies kicking the third body out in an arbitrary direction, while the two remain orbiting each other. So statistically there should be lots of objects in the galaxy whose motion does not match the general rotational velocity of the Milky Way.
The magnitude and direction are still statistically significant. From the Scientific American article:
If ‘Oumuamua came from a typical star, it must have been ejected with an unusually large velocity kick. To make things more unusual, its kick should have been equal and opposite to the velocity of its parent star relative to the LSR, which is about 20 kilometers per second for a typical star like the sun. The dynamical origin of ‘Oumuamua is extremely rare no matter how you look at it.
Are they suggesting some civilization managed to build a probe that can travel at an appreciable percentage of the speed of light?
That's not what he's saying at all. He's saying the objects motion is statistically unlike anything else in our part of the Milky Way. It's essentially stationary with respect to the rest of the galaxy. A large amount of energy would be needed to achieve that relative velocity. He also notes that it has several characteristics, including acceleration, that are similar to current solar sail technology. It's a statistical anomaly.
I may have missed something, but he also doesn't mention it being uses specifically to study Earth. His hypothesis is that its use is to mark a specific reference point in the galaxy. Our solar system passed by it, not the other way around.
I have a Rumba. It does its jobs and keeps my floor clean, but it isn't as good as if I were to do it myself. As I can vacuum my whole house in about 30 minutes, while the Rumba just does the first floor in about an hour (and misses spots). But what it is good at is the fact that it does this scheduled daily. Where I only have the time to do this weekly.
This is a prefect example of comparative advantage. You are more efficient at vacuuming the floor, but your time is more useful for other tasks. While the Roomba is less efficient than you, it literally has nothing better to do. Therefore it makes the most sense to have the Roomba vacuum the floor.
The hypothesis that was being tested was that the more frequent heat waves at this location would result in smaller insect populations. This was based on previous research conducted in a laboratory environment. The data collected confirmed the hypothesis. This was not a random survey looking to explain the results.
We need to reduce our footprint on the planet, and the only sure way that we know will definitely work is by drastically reducing our numbers. Which is not a thing that will voluntarily happen...
It can and it has. As soon as people can afford contraception, they use it!
The population side will take care of itself. However, a per-person CO2 reduction still needs to happen.
Of all kinds of taxation, I'd prefer the speed cameras, because I can avoid paying by sticking to the posted speed limit.
Would you feel the same way if the government began lowering the speed limits? From TFA:
Speed limits in France were already controversial after the government lowered the limit on many main roads from 90km/h to 80km/h (50mph) early last year.
According to TFA, this was caused by stolen devices being in areas without a cell signal, and falling back on WiFi access point geolocation.
You read the wrong article. That's the case for the home in Atlanta.
TFA is actually the result of someone at the NGA deciding this guy's house was the geographical center of Pretoria. As is the case with the farm in Nebraska, any unknown location in Pretoria defaults to the geographical center. They emailed the NGA (who would have thought?) and the issue has been corrected. The default location is now Church Square in the NGA database.
The must have forgotten to include work hours as a factor in this analysis. A lot of those medical professions have terrible hours. Although advancements in medicine have improved things, obstetricians don't usually get to schedule when children are born.
Looking through the Honda system, I noticed it's Android based. I think Android is a major enabler for Linux domination, as automakers don't have to start with a bare kernel.
Clearly you have never burned plastics before. Its a nasty process that releases lots of weird toxic fumes.
Depends on the temperature, pressure, and atmosphere you burn it under. A simple higher temperature, like found in an incinerator, will turn common plastic (polythene, polypropene, styrene, butadiene, acrylonitrile, ) into H2O, CO2, and N2.
In practice you get some NOx rather than N2 from acrylonitrile. And some chlorine compounds if there is any polyvinyl chloride in the mix. You can deal with both with some chemistry in the scrubbers. Some waste compounds like formaldehyde are valuable for making more plastic.
As a mechanical engineer working in the field of combustion, both are true. You may have heard the old saying, "where there's smoke, there's fire." Well, that's not really true. Where there's smoke, there's incomplete combustion. Burning organic chemicals like many plastics will reduce in to water vapor and carbon dioxide in many cases, provided the combustion is hot enough and in the presence of a catalyst. However, not all plastics are simple ethylene chains. Plastics such as vinyl have chlorine atoms that can produce toxic gases.
Call it hacking and it's good, call it GMO and it's bad.
GMOs aren't bad, it's the modifications that are made that are bad.
Growing faster with fewer resources = good modification.
Able to resist being covered in increasingly caustic pesticides = bad modification.
It's generally the undiscovered side effects of GMO that people are afraid of. People aren't used to getting something for free, that's not how the world typically works. Therefore any improvements from GMO makes them concerned about what they are giving up. People in this discussion are already talking about that.
Unlike climate, economics is not a natural system, but an artifical one. Despite all the bullshit rhetorics that makes it seem like economics is some kind of higher power, we humans decide how it works and where it goes. Anyone who tells you the opposite stands to profit from that falsehood.
If that were 100% true, you would think we could force our man-made economic system to constantly provide optimal outcomes. Unfortunately, it doesn't work that way.
We can't simply change the laws of economics and have it work. They are rooted in sociology, which is unfortunately an incredibly poorly researched field. We simply don't know enough about human nature to bend society and economics to our will. So, although economics is "artificial' in that it's a system made up of humans, it's also a system that developed organically.
One of my favorite examples of the sociological side of economics is the Plano Real.
I'm glad Purdue is getting some dividends out of that nanotechnology center they built 10 years ago. That thing always gave me the creeps. Probably because I watched too much Star Trek as a kid.
I suspect he might have achieved better spread and more glitter using a small CO2 cylinder. Maybe in 2.0.
Doubtful. The device looks similar to a broadcast spreader, which is where I'm guessing he got his inspiration. There's a reason that design is popular for landscaping. It achieves very even results. A CO2 cylinder would likely result in a shotgun pattern, which will end up covering a much smaller area.
Why do people find it acceptable that valuable packages are just left on the doorstep ?
Because you shouldn't have to worry about someone stealing from you, even if it's out in the open.
Why do people find it acceptable for the police to not investigate these crimes? Hopefully the GPS and video evidence is enough to persuade them to press charges this time. However, I suspect the police are too concerned with crimes that generate revenue for the department, like traffic violations.

Is this the latest article from Kashmir Hill? At the rate she's going, she'll be writing articles on a typewriter next month.

...and live somewhere with lots of rainfall.
There's the problem. Too many people live west of the 100th meridian.
1. Remove 2 billion people from the planet.
Which 2 billion? It makes a difference. 2 billion Americans and Europeans will have a much bigger impact than 2 billion Africans and Asians.
No need to speculate. Here's the data.
Your conclusions sound straight out of Hans Rosling's book. Although chapter 9 suggests we shouldn't blame Exxon-Mobil. We're all to blame.

Natural gas produces 50-60% less CO2 than a coal plant for the same amount of energy. That means a lot of new capacity has been added to the grid.

The device he created for distributing the glitter was a work of genius. Watch the videos, it is an amazing and beautiful creation.
