Cell Transplant Allows Paralyzed Man To Walk

DavidMZ A previous attempt did not succeed that well (161 comments)

From the Daily Mail:

A woman has developed a nose-like growth eight years after a stem cell treatment to cure her paralysis failed. At the Hospital de Egas Moniz in Lisbon, Portugal, the unnamed woman, a U.S. citizen, had tissue from her nose implanted in her spine. Doctors hoped the cells would develop into neural cells and help repair the nerve damage to the woman's spine. But the treatment failed. However, last year, eight years after the stem cell operation, the woman, then 28, complained of increasing pain in the area. Doctors discovered a three-centimetre-long growth, which was found to be mainly nasal tissue, as well as bits of bone and nerve branches that had not connected with the spinal nerves.

CIA Tested Primitive Chatbots For Interrogation In the 1980s

DavidMZ It's not the agents who were taking LSD (65 comments)

Drugs, other chemicals, and different forms of abuse have been investigated by the CIA as interrogation tools in the frame of Project MKUltra. Compared to those, Analiza looks like a mildly annoying joke.

CIA Tested Primitive Chatbots For Interrogation In the 1980s

DavidMZ Re:Comparison (65 comments)

Analiza is an AI the same way that Babbage's analytical engine is an iphone. It probably just made the subject get mad and proclaim "I hate interrogators!"

Isn't that the point of interrogation?

China Pulls Plug On Genetically Modified Rice and Corn

DavidMZ Re:Better to starve I guess? (152 comments)

It's funny that you made an almost identical answer a couple of posts above this one. Why don't you just cut-and-paste, like any normal person would do?

It produces a poison in the same sense that chocolate and grapes are poisonous (don't feed those to your dog). The Bt protein has a very specific mode of action in certain insect pests, and does not impact humans. It is not a health concern, and has been used in organic food production for decades before suddenly becoming controversial once genetic engineering got involved. Also, that a plant produces a poison is not an alarming thing. In fact, it is ubiquitous. Chemical defenses are found throughout the plant kingdom, including in crop plants. Things like solanine in potatoes, or glucosinolates in broccoli, or even caffeine in coffee and tea (note that they are produced respectively in the seeds and leaves, two things a plant might want to defend...that humans like them for it is kind of an evolutionary plot twist) all have insecticidal properties. Anti-GMO groups love to be alarmist over the fact that some GMOs produce an additional insecticide (yes, one more, even non-GMO corn is going to have things like maysin in it) but in and of itself is not alarming. It's just preying on the ignorance of those who do now know just how many natural pesticides we consume daily.

10:54 am

It produces Bt, which is toxic to certain orders of insects, not to humans. And before someone comes along and says that it is still toxic, remember that gapes and chocolate are toxic to dogs, and dogs are a lot more closely related to humans than lepidopterans. Oh, and every plant produces insecticides anyway. It's only alarming if you don't know much about plant biochemistry. Give something that can't swat back at the trillions of things out there trying to eat them a few hundred million years to come up with defenses and they develop things chemical defenses, like caffeine (yep, it has insecticidal properties, ever wonder why coffee evolved to have it right in it's seeds?), piperine (a yummy insecticide, turns out black pepper's original plan was to not have things eat its offspring), maysin (found even in your non-GMO corn) solanine (tomatoes and potatoes, don't eat this) and falcarinol (found in carrot a neurotoxin in high enough quantities).

Can Our Computers Continue To Get Smaller and More Powerful?

DavidMZ Size matters but... (151 comments)

Actually, it's not necessarily true that making a device smaller will reduce the current/power consumption. It will indeed reduce the power used for switching the CMOS, but you might have to deal with higher leakage currents. That's why the industry is working with new materials (High-k dielectrics, metal gates, III-V), with new structures (Fully Depleted SOI, FinFETs, Nanowires for logic, VNAND for memory), and with 2.5D/3D integration scheme.

You're right when we say that "basic silicon technology is hitting the limits" but the real question is: will it be economically viable to go beyond the basic silicon technology?

Telegram Not Dead STOP Alive, Evolving In Japan STOP

DavidMZ 25 characters is too much for Haikus! (144 comments)

They should have limited it to 17 characters. Since in Japanese each character of the two phonetic alphabets corresponds to a syllable, it would have been perfect for Haikus!

Soccer Talent Scouting Application Teams Up With Video Game Publisher

DavidMZ The Numbers Game (39 comments)

Although football is a still late in the numbers race compared to some other sports, it is rapidly catching up. For a nice view of the power of numbers in football, and what makes football unique as a sport, I strongly recommend reading The Numbers Game .

3 Congressmen Trying To Tie Up SpaceX

DavidMZ Re:What? (393 comments)

You don't have to look hard to find instances where the government is creating wealth: infrastructures, education, defense,... A road creates wealth as it allows better communication and transportation and goods; schools create wealth by educating individuals who will turn to be more productive than their non-educated fellows; soldiers create wealth by defending our territory and defending our interests abroad.

As for the higher efficiency of private enterprise, it is in true only as far as there is a healthy competition, and there are lots of instances (such as this ULA case) where this is questionable

Chinese Couple Sells Children To Support Online Game Addiction

DavidMZ Re:Silly season much (131 comments)

Doesn't China still have a 1 child law.

Not exactly, it depends on the number of siblings you have:
- if both members of a couple are single children, they are allowed to have two kids.
- if at least one of them is not a single child, they are not allowed to have more than one kid.

There is also the possibility to pay for the "right" to have additional children, and I think that you then also have to pay for their education and medical expenses (whereas those are free for the 1st child).

Actually, if you look at the demographics of China, the success of the one-child policy results in a quick aging of the population which forces them to revise this policy.

Samsung Debuts Thin Galaxy Tab S With Super AMOLED 2560X1600 Display

DavidMZ Re:Units! (176 comments)

well, screens are even in metric countries still mostly measured in inch.

It depends on the countries. From the countries I have seen:

- UK, Japan: still using inches for TV screens

- France, Germany: using cm for as long as I remember

Isolated Tribes Die Shortly After We Meet Them

DavidMZ Pre-columbian estimates (351 comments)

In the book 1491, Charles Mann tries to summarize the current knowledge on Pre-columbian Americas. Based on demographics and epidemiologic studies, he comes with a mortality rate for american Indians after encounter with European in the 90-95% range, which means that America before Columbus would have been very densely populated. Although there is a high uncertainty in this number due to the scarcity of data, the 80% of this study definitely supports the pre-Columbian values, especially if we consider the differences in access to medicine. And yeah, this is grim stuff.

Scientists Solve the Mystery of Why Zebras Have Stripes

DavidMZ Hypothesized in 1982 - more proof in 2014 (190 comments)

AFAIK the Waage study did not map the respective habitats of zebras and flies; that is what is actually new in this study, and it supports the Waage hypothesis.

Mysterious hole spotted at the 'end of the world'

DavidMZ DavidMZ writes  |  about 4 months ago

DavidMZ (3411229) writes "The Siberian time published a story about a large crater of unknown that appeared in the Yamai peninsula in northern Siberia.
Russian government has dispatched a group of scientists to investigate the origin of the crater. Although early explanations included meteorites and UFOs, Anna Kurchatova from Siberia’s Sub-Arctic Scientific Research Centre believes that the crater was a result of an explosion when a mixture of water, salt and natural gas exploded underground. The Yamai peninsula is known to hold Russia's biggest natural gas reserve."
