Oldest Human Genome Reveals When Our Ancestors Mixed With Neanderthals

grouchomarxist Re:Title seems a bit racist (127 comments)

I was wondering when the ugly racist interpretation was going to raise its head. So, far a long time Neanderthals were thought of as more primitive than humans, but now that it is known that most Europeans have Neanderthal DNA (and most Africans don't), they are being re-interpreted as being the origin of the master race.

Lockheed Claims Breakthrough On Fusion Energy Project

Maybe not...

The problem with any source of energy is that it can be weaponized.

The grandparent is wrong about all three. They are probably facetiously referring to the American military bases located in these countries.

Co-Founder of PayPal Peter Thiel: Society Is Hostile To Science and Technology

grouchomarxist Re: Peter Thiel is on a book tour or something... (238 comments)

I don't think a publicist would help unless they could get Thiel to change his behavior. The fact is that Musk is getting stuff done while Thiel seems to mostly complain about other people not getting stuff done.

They're friends, but while Musk is doing great things, Thiel mostly makes news complaining.

2014 Nobel Prize In Physics Awarded To the Inventors of the Blue LED

grouchomarxist Re:Misleading title, probable Western propaganda (243 comments)

I looked around a bit and I found no evidence that Alferov did work in this particular area. In particular, Akasaki, Amano and Nakamura worked on Gallium Nitride research, which Alferov doesn't appear to be involved with. Alferov did do research that is foundational in solid state physics. Alferov also won a Nobel Prize in Physics, so I don't think there is any effort to suppress his contributions.

2014 Nobel Prize In Physics Awarded To the Inventors of the Blue LED

grouchomarxist Re:Inventors of the first commercially worthwhile (243 comments)

Can you point to a place where the Nobel site is incorrect? Note that the Prize is for "efficient blue light-emitting diodes", not the first. Also if you look at this document is specifies that the work was in efficient blue LEDs and mentions earlier work on blue LEDs.

2014 Nobel Prize In Physics Awarded To the Inventors of the Blue LED

grouchomarxist Re:As well they should. (243 comments)

According to this document from the Nobel committee, white LEDs emit more than 300 lm/W, while CFLs are at 70 lm/W. This suggests white LEDs are more than 4 times as efficient than CFLs.

2014 Nobel Prize In Physics Awarded To the Inventors of the Blue LED

grouchomarxist Re:Useful but physics? (243 comments)

Apparently the Nobel Prize in Physics also goes to inventions. See this comment: 'Nobel Prizes in physics often go to fundamental discoveries such as the Higgs Boson. But when the committee makes an award for an invention, "we really emphasize the usefulness of the invention," said Anne L'Huillier, an atomic physics professor at Lund University in Sweden, also speaking at the press conference. And the blue LED is nothing if not useful.' (From here.)

The Nobel Prize in Physics was previously awarded for the inventions of the transistor and integrated circuits.

Factory IoT Saves Intel $9 Million

grouchomarxist Re:Internet of Stupidity (50 comments)

The more precise term is Industrial Internet which is considered a subset of the Internet of Things. It is considered a subset because the same types of technologies are being used.

The Internet of Things doesn't require third-parties, but such third-parties are often helpful if they provide useful services.

Apple Allegedly Knew of iCloud Brute-Force Vulnerability Since March

grouchomarxist Ibrahim Balic... (93 comments)

Ibrahim Balic is the researcher who in the past claimed to have been responsible for uncovering a flaw that brought down Apple's Dev Center. As it turned out, he uncovered a lesser problem around the time a more significant flaw was exploited. It seems that he is a bit of an attention seeker, so I would take anything that comes from him with a grain of salt.

I can't find the exact links that cover the older story, but here are some related ones:

Europeans Came From Three Ancestry Groupings

grouchomarxist Re:Finnish (85 comments)

You don't need to learn languages to do linguistics. You need to learn about languages. It helps to know the languages involved, but if that was required comparative linguistics would get nowhere. Comparative linguistics works by building on the data gathered about the target languages, often by researchers who went to study them.

2014 Nobel Prize in Physics awarded to the inventors of the blue LED

grouchomarxist grouchomarxist writes  |  about three weeks ago

grouchomarxist (127479) writes "The 2014 Nobel Prize in Physics has been awarded to Isamu Akasaki, Hiroshi Amano and Shuji Nakamura, the inventors of the blue LED.

When Isamu Akasaki, Hiroshi Amano and Shuji Nakamura produced bright blue light beams from their semi-conductors in the early 1990s, they triggered a funda-mental transformation of lighting technology. Red and green diodes had been around for a long time but without blue light, white lamps could not be created. Despite considerable efforts, both in the scientific community and in industry, the blue LED had remained a challenge for three decades.

They succeeded where everyone else had failed. Akasaki worked together with Amano at the University of Nagoya, while Nakamura was employed at Nichia Chemicals, a small company in Tokushima. Their inventions were revolutionary. Incandescent light bulbs lit the 20th century; the 21st century will be lit by LED lamps.

White LED lamps emit a bright white light, are long-lasting and energy-efficient. They are constantly improved, getting more efficient with higher luminous flux (measured in lumen) per unit electrical input power (measured in watt). The most recent record is just over 300 lm/W, which can be compared to 16 for regular light bulbs and close to 70 for fluorescent lamps. As about one fourth of world electricity consumption is used for lighting purposes, the LEDs contribute to saving the Earth’s resources. Materials consumption is also diminished as LEDs last up to 100,000 hours, compared to 1,000 for incandescent bulbs and 10,000 hours for fluorescent lights.

The LED lamp holds great promise for increasing the quality of life for over 1.5 billion people around the world who lack access to electricity grids: due to low power requirements it can be powered by cheap local solar power.

The invention of the blue LED is just twenty years old, but it has already contributed to create white light in an entirely new manner to the benefit of us all.

Shuji Nakamura went on to develop the white LED and the blue laser which is used in Blu-Ray devices."

Physicists claim detection of dark matter

grouchomarxist grouchomarxist writes  |  more than 2 years ago

grouchomarxist (127479) writes "Physicists at the University of Michigan claim that they have made the first detection of dark matter. 'Dark matter, whose composition is still a mystery, doesn't emit or absorb light, so astronomers can't see it directly with telescopes. They deduce that it exists based on how its gravity affects visible matter. Scientists estimate that dark matter makes up more than 80 percent of the universe. To "see" the dark matter component of the filament that connects the clusters Abell 222 and 223, Dietrich and his colleagues took advantage of a phenomenon called gravitational lensing. They were able to determine the extent to which the supercluster distorted galaxies, and with that information, they could plot the gravitational field and the mass of the Abell 222 and 223 clusters. "It looks like there's a bridge that shows that there is additional mass beyond what the clusters contain, the clusters alone cannot explain this additional mass," Dietrich said.' Article in nature is here."

grouchomarxist (127479) writes "Microsoft is considering selling the Zune subsidized like a cellphone, according to this excerpt on MarketWatch from a PC World magazine interview with Microsoft's Zune marketing director, Jason Reindorp. According to the article: "The spokesman said that Microsoft first considered the cellphone-like distribution plan after seeing interest in its Zune Pass subscription service, which offers monthly paid access to songs on the Zune Marketplace, a competitor to Apple's iTunes store. Though he declined to say how many subscribers currently use Zune Pass, the spokesman said subscriptions rose 65% during January." The PC World interview doesn't appear to be available yet online."
