Also, recreating Earth-like conditions won't change the fact they would be living in 1/3rd gravity, which would definitely invoke some selection pressure.
2. I'm a (lacto-ovo) vegetarian myself and don't eat meat at all. A proper vegetarian diet is just as good as an omnivorous diet (if not better), it just requires a little more planning, a vegan diet much more so, and I see a fair number of people following that trend and harming themselves by not doing their homework.
We already are stopping population growth. Birth rates in Europe and North America have been below replacement rate for decades and the world population growth rate has been dropping since the 60s.
At current trends, the world population will level off at a little more than 9 billion around 2050 and start to drop slowly after wards.
20 billion people is extremely unlikely unless the population growth rate, which has been dropping for the past 50 years, suddenly increases again. Current projections show the world population will level off a little past 9 billion around 2050.
Relying on lentils as your sole protein source is a bad idea. Proteins from plants are always incomplete proteins, which means they're missing at least one of the essential amino acids. Lentils are missing methionine and cystine. You need to mix at least 2 sources (Rice and lentils, for example) to get useful complete protein.
1 and 2 are already happening everywhere in the western (North America and Europe) world. Our birth rate has been below replacement rate for a couple decades now. Immigration is the only thing keeping population growth going.
Different levels of government. Municipal and State governments have decided its legal, but the federal government says it's still illegal.
Eventually the supreme court is going to have to decide something on this unless the DEA gets their heads out of their asses (hah!), but until then, we've got a screwy situation.
He ought to add a percentage question or two to that test. I'm frequently amazed by the number of people who cannot correctly calculate sales tax or a discount.
Yes, lack of buffers would be bad, as even a trivial delay would result in a packet getting dropped. Oversized buffers are also bad, as they simply delay the packet getting dropped, preventing congestion control from reacting in a timely manner. The buffers need to be sized appropriately relative to the link speed and typical latency.
A lack of a buffer is bad, as even if a packet had to be buffered for a microsecond, it would still be dropped as it couldn't be transmitted immediately.
But a too large buffer is also bad, as it delays the packet being dropped until it times out, preventing TCP's congestion control functionality from rapidly responding to the congestion (by shrinking the window size). Eventually, it will detect the packets getting dropped as they time out, but in the meantime (possibly several seconds), it continues merrily transmitting packets, which will also get dropped, resulting in a massive spike in latency whenever it happens, as it then needs to retransmit all of those dropped packets.
With an appropriately sized buffer, small delays would result in data being buffered for short times, but if it would face a too long delay (determined by the buffer being full), it would simply get dropped, alerting everyone to slow down, resulting in only a small number of packets needing to be retransmitted and preventing a large latency spike.
Your system is uploading data to somewhere. At some point in the path, one link is congested. The router on your end of that link should drop packets it cannot fit into that link in reasonable time, and when your system (and everyone else with data going through that link) detects the packets got dropped, it will shrink the TCP window size and transmit more slowly to compensate for the congestion, but instead, it [the router] accepts your packets and puts those in its oversized (too large relative to the link speed. Say, a 5MB buffer, but the link speed is only 1MBps. Any packets stuffed into the end of that buffer will end up waiting 5 seconds (far too long) until they get transmitted) buffer to await transmission through the congested link. Eventually, those buffered packets will time out and be considered dropped, but in the meantime, your system (and everyone else with data going through that link) is continuing to send data (which will also be buffered and later dropped) oblivious to the problem and the window size doesn't get adjusted for quite some time, effectively breaking the congestion control system, as it relies on being able to detect congestion quickly and respond to it. This results in massive swings in latency, which wreck havoc with interactive applications, such as VOIP, VNC, games, etc.
If my kids are vaccinated, they're not at risk and neither am I.
Yes, you are at risk, as no vaccine is or can be 100% effective at promoting immunity. For example, the usual 2 dose measles vaccine is about 98% effective.
I dunno about the US, but Hep-B is typically given at 2 months (and again at 4 and 6 months) up here in Canada, unless the mother is a carrier, then it's done immediately at birth, then at 2 and 4 months. Or alternatively, sometime between 7 and 17 years on the same staggering schedule.
I'm not aware of any reasonable risk that elementary kids are having unprotected sex at school. And yet it is required for entry where I live. There are more...
There are other ways to get hepatitis B than unprotected sex. Blood transfusions, piercings, etc.
I don't agree, we have to allow those who don't have common sense to suffer the consequences.
The problem is that doesn't work with vaccines. Vaccines aren't and can't be 100% effective. For example, the standard 2 dose measles vaccination is about 98% effective. And you also need to consider people who simply cannot be vaccinated for various reasons, most commonly allergic reactions.
With sufficiently high coverage, those 2 sets are covered by herd immunity, but if that coverage drops, that protection goes away and you get the potential for sustained outbreaks and the possibility of the virus mutating into a new strain that the vaccine does not cover.
You're missing the point of the flu vaccine. Giving the vaccine to the elderly, AIDS patients, etc. won't do much. They're at risk for serious complications because they already have immune system problems, and vaccinating won't help that.
The point is to protect them via herd immunity by vaccinating everyone around them. If no one around them can transmit the disease, there's no way they can catch it.
"Herd Immunity" means "developing immunity from catching it from someone else".
No, it doesn't. Herd immunity means that if enough of a population is immune, those who aren't immune (e.g. people who have compromised immune systems or who can't be vaccinated for various reasons) are unlikely to be infected as there won't be any vector for them to acquire it from.
e.g. If everyone around you is immune to measles, you won't be able to catch measles as there's no one who can transmit it to you.
It was developed to treat angina and hypertension: it wasn't until the first medial trials that they realised it didn't work for those
It works fine for those, but it interacts badly with nitroglycerin (causes blood pressure to fall dangerously low), which along with aspirin, is the frontline post-heart attack treatment, so that interaction is highly undesirable, and there are other treatments that work just as well and don't have that problem.
It's not issued to all soldiers, only ones deployed to Korea or the middle east.
Smallpox not gone, it's just not in the wild. There are still samples of the virus in high security labs, which could potentially be used for biological warfare.
Furthermore, while there has not been a known wild case in over 30 years, there is a chance there may still be unreported cases in isolated parts of the world such as some middle east countries or North Korea.

My concern with the patents on WebM boil down to the simple fact that Google won't indemnify users.
MPEG-LA won't indemnify you either. If someone outside their patent pool sues you, they're not going to be helping.
Submarine reactors are measured in tens of kilowatts, much too small to be of practical use for power generation.
Earth-like? Which part of Earth?

Might try a style of frame with larger lenses/larger reading section or look into inverted bifocals, which have the near/distance sections swapped.

$70B? The Apollo project cost about $170B (2005 dollars) and Mars is 150x further away than the moon is.
Spirit and Opportunity have collectively covered 33 kilometres of ground over 6 years. How long would it take a human to cover that? A week? Less?
