Judge Rules Drug Maker Cannot Halt Sales of Alzheimer's Medicine

mspohr Re:Can you say... (263 comments)

If you think that the medical industry exists only to make money, then the drug companies are rational.
All of your anger at the government is really anger at companies who have corrupted government. In the US, government works for corporations and rich people and has been completely corrupted (some people call this fascism).
The government created patents to help companies, not people.
Get rid of patents... problem solved... no more evil drug companies.

California's Hydrogen Highway Adds Another Station

mspohr Re:I suppose this is a good thing... (87 comments)

Most hydrogen comes from natural gas (with lousy conversion efficiency. If you get your hydrogen from electricity, it has even worse efficiency. It uses about four times the electricity to make hydrogen and then convert it back to electricity in your "fool cell" vehicle as just putting the electricity in your vehicle and bypassing the whole hydrogen part.
Plus, electricity is everywhere, literally everywhere. Anyone can just plug in at home and work, etc. With hydrogen, you have only ten places to refuel in California... not going very far.

NSF Accused of Misuse of Funds In Giant Ecological Project

mspohr Re:Republican business as usual... (116 comments)

The complete paragraph is:
"But a 2011 audit of the project’s proposed construction budget stalled three times when, according to the independent Defense Contract Audit Agency (DCAA), NEON’s accounting proved so poor that the review could not be completed. Eventually, DCAA issued an adverse ruling, concluding that nearly 36% of NEON’s budget proposal was questionable or undocumented."

They had poor accounting. They have not been given a chance to explain or improve their accounting. This is a lot different than fraud. My cognitive bias is against the Republican climate deniers. If the worst thing they can come up with is coffee and t-shirts, this is just theater.

NSF Accused of Misuse of Funds In Giant Ecological Project

This is just the usual Republican FUD trying to kill something that might give us some actual numbers about climate change.

- $3,000 for t-shirts... oh, the corruption! what is the world coming to???

Really... is this the best they can come up with???

After the hearing, DCAA director Bales said she was not impressed by the scale of the alleged misconduct. “In the contract world, we do a lot of reports that disallow this kind of thing. So, you know, people do it,” she said. “But then we identify it.”

Also significant was that the project managers were not invited to the hearing, thus insuring that this would be a true kangaroo court.

Why Elon Musk's Batteries Frighten Electric Companies

mspohr Re:Are they really that scared? (461 comments)

You are right that electric cars (and solar electricity) are a big market opportunity for electric companies since they could charge more for managing the grid.
However, this would require a change in their thinking and business model and you have to remember that these companies are fat, lethargic entrenched monopolies who just want to collect money and do not want to have to think too hard or change anything so their first reaction is to try to ignore and obstruct any change. They are afraid of change. It's just like the taxi companies and Uber or the music business and mp3s.
So yes, they are awful, evil power monopolies and they are afraid... I like the smell of disruption in the morning.

Why Elon Musk's Batteries Frighten Electric Companies

mspohr Re:Are they really that scared? (461 comments)

I know it's a big mental strain, but you could try reading TFA and if you did you would find these quotes:
“Electric vehicles can be the best thing to ever happen to our industry or the worst thing to ever happen to our industry,” said James Avery, a senior vice president at San Diego Gas & Electric."

Last year, Pinnacle West Capital Corp.’s Arizona Public Service raised the ire of its customers and the solar industry by tacking on a monthly fee of about $5 for residents with solar systems. Adding fixed connection charges or additional fees to such customers may cause more of them to defect, said Lovins of the Rocky Mountain Institute.

“The mortal threat that ever cheaper on-site renewables pose” comes from systems that include storage, said Amory Lovins, co-founder of the Rocky Mountain Institute, a Snowmass, Colorado-based energy consultant. “That is an unregulated product you can buy at Home Depot that leaves the old business model with no place to hide.”

Two Google Engineers Say Renewables Can't Cure Climate Change

mspohr Re:Deliberate (652 comments)

Nuclear power is pretty safe but not perfect. Coal is terrible. I think they both should be decommissioned as quickly as possible.
The problem is that "pretty safe" is not good enough. Nuclear power has had two serious accidents, rendering two regions uninhabitable for the the foreseeable future. I don't think it's reasonable to have "accidents" regularly which destroy entire regions. It's only a matter of time until the next accident.
Nuclear costs much more than renewables, takes longer to build, and regularly destroys regions. Renewables are cheaper, faster to build and don't have the toxic side effects of coal and nuclear. Much better investment.

Darwin Awards study says men are far more idiotic than women

mspohr (589790) writes "In a study published in the British Medical Journal (http://www.bmj.com/content/349/bmj.g7094) and reported by CNet (and others): "Scientists analyze the past 10 years of silly, avoidable deaths and find that almost 90 percent of the "protagonists" in these scenarios were male." "According to “male idiot theory” (MIT) many of the differences in risk seeking behaviour, emergency department admissions, and mortality may be explained by the observation that men are idiots and idiots do stupid things." The BMJ Abstract: "Sex differences in risk seeking behaviour, emergency hospital admissions, and mortality are well documented. However, little is known about sex differences in idiotic risk taking behaviour. This paper reviews the data on winners of the Darwin Award over a 20 year period (1995-2014). Winners of the Darwin Award must eliminate themselves from the gene pool in such an idiotic manner that their action ensures one less idiot will survive. This paper reports a marked sex difference in Darwin Award winners: males are significantly more likely to receive the award than females (P0.0001). We discuss some of the reasons for this difference." Yes, please discuss..."

Is the Universe a Hologram?

mspohr mspohr writes  |  about 3 months ago

mspohr (589790) writes "An article in The Register explains an experiment at Fermilab:
"How can we tell from the inside of our Universe if it’s actually real or just a hologram? Boffins at Fermilab have set out to answer this thorny question with a new experiment in the National Accelerator Lab called the Holometer."
"Scientists reckon it’s possible that, just like the pixels that make up the 3D image on your TV, all the information about the Universe could actually be encoded in tiny packets in just two dimensions. These natural pixels would be ten trillion trillion times smaller than an atom – a unit known as the Planck length. Things get heavily quantum from this assumption on"
(Note: I always get confused when things get "heavily quantum".)
"The Fermilab’s Holometer will attempt to measure the quantum jitter of space itself using a pair of interferometers placed close together. Each instrument will send a one-kilowatt laser beam at a beam splitter and down two perpendicular 40m arms. The light will then be reflected back to the splitter when the two beams recombine, creating fluctuations in the brightness if these vibrations exist."
(Sounds good so far...)
“If we find a noise we can’t get rid of, we might be detecting something fundamental about nature – a noise that is intrinsic to space-time,” said Fermilab physicist Aaron Chou, lead scientist and project manager for the Holometer. “It’s an exciting moment for physics. A positive result will open a whole new avenue of questioning about how space works.”
(Yes... how does space work?)"

New tools help neuroscientists analyze 'big data'

mspohr mspohr writes  |  about 5 months ago

mspohr (589790) writes ""New technologies for monitoring brain activity are generating unprecedented quantities of information. That data may hold new insights into how the brain works — but only if researchers can interpret it. To help make sense of the data, neuroscientists can now harness the power of distributed computing with Thunder, a library of tools developed at the Howard Hughes Medical Institute's Janelia Research Campus.
"Freeman chose to build on a new platform called Spark. Developed at the University of California, Berkeley's AMPLab, Spark is rapidly becoming a favored tool for large-scale computing across industry, Freeman says. Spark's capabilities for data caching eliminates the bottleneck of loading a complete data set for all but the initial step, making it well-suited for interactive, exploratory analysis, and for complex algorithms requiring repeated operations on the same data. And Spark's elegant and versatile application programming interfaces (APIs) help simplify development. Thunder uses the Python API, which Freeman hopes will make it particularly easy for others to adopt, given Python's increasing use in neuroscience and data science.
Researchers can find everything they need to begin using the open source library of tools at http://freeman-lab.github.io/t...
To make Spark suitable for analyzing a broad range of neuroscience data — information about connectivity and activity collected from different organisms and with different techniques — Freeman first developed standardized representations of data that were amenable to distributed computing. He then worked to express typical neuroscience workflows into the computational language of Spark.""

Earth in the midst of sixth mass extinction - the "anthropocene defaunation"

mspohr mspohr writes  |  about 5 months ago

mspohr (589790) writes "A special issue of Science magazine devoted to Vanishing Fauna publishes a series of articles about the man-caused extinction of species and the implications for ecosystems and the climate.
"During the Pleistocene epoch, only tens of thousands of years ago, our planet supported large, spectacular animals. Mammoths, terror birds, giant tortoises, and saber-toothed cats, as well as many less familiar species such as giant ground sloths (some of which reached 7 meters in height) and glyptodonts (which resembled car-sized armadillos), roamed freely. Since then, however, the number and diversity of animal species on Earth have consistently and steadily declined. Today we are left with a relatively depauperate fauna, and we continue to lose animal species to extinction rapidly. Although some debate persists, most of the evidence suggests that humans were responsible for extinction of this Pleistocene fauna, and we continue to drive animal extinctions today through the destruction of wild lands, consumption of animals as a resource or a luxury, and persecution of species we see as threats or competitors.

California pays Wisconsin farmer to burn methane

mspohr mspohr writes  |  about 7 months ago

mspohr (589790) writes "Can bottom-up cap and trade work?
California has funded a $3.2 million system to burn methane from dairy cows in Wisconsin.
It's all part of California's "cap and trade" effort to reduce climate change.
"California’s program is the latest incarnation of an increasingly popular — and much debated — mechanism that has emerged as one of the primary weapons against global warming. From China to Norway, Kazakhstan to the Northeastern United States, governments are requiring industries to buy permits allowing them to emit set levels of greenhouse gases. Under these plans, the allowable levels of pollution are steadily reduced and the cost of permits rises, creating an economic incentive for companies to cut emissions."
“We might be witnessing the birth of a new system, without quite realizing it,” said Glen P. Peters, a climate researcher at the Center for International Climate and Environmental Research in Oslo. “When you think of all these bottom-up initiatives around the world, maybe we are living through the transformation right now.”
"Experts who support cap and trade contend that a market mechanism can reach more deeply into the economy than any other approach, changing the behavior even of people and companies that might not necessarily care about global warming.""

Claims of virgin births in U.S. near 1 percent

mspohr mspohr writes  |  1 year,3 days

mspohr (589790) writes "Each year, the British Medical Journal (BMJ) publishes a set of interesting articles which are, while scientifically correct, do not meet the usual criteria for publication (untraditional papers).
This highlight of this year's edition is one which found that 0.8% of US females reported virgin births. That is, they reported that they had never had intercourse and that they had been pregnant. It should be noted that they did not claim immaculate conception, they just reported (on regular surveys) that they had been pregnant and (in a separate section of the survey) had never had intercourse.
"The authors of "Like a virgin (mother)" — whose prose is devoid of irony — say such scientifically impossible claims show researchers must use care in interpreting self-reported behavior. Fallible memory, beliefs and wishes can cause people to err in what they tell scientists."
These results are from a large, well regarded, longitudinal study of women in the USA.
Some insight into these findings:
"Of those who said they became pregnant as virgins, 31 percent also said they had signed chastity pledges; 15 percent of nonvirgins who became pregnant said they had signed such pledges, in which a girl vows not to have sex until she marries."
Also:
"The ostensibly chaste mothers were also less likely to know how to use condoms, according to the report. " (duh... this could be a big clue here!)
Finally the authors also report (again, without irony) that: "The researchers found that although the mothers in question were more likely to have boys than girls, and to be pregnant during the weeks leading up to Christmas, neither similarity to the Virgin Mary was statistically significant."
Merry Christmas to Jesus and all the gang."

These two engineers wrote software to test for vulnerabilities in the control systems of electrical power grids which use a protocol called DNP3 to communicate with sub-stations. They first tested an open source implementation of the protocol and didn't find any problems. They were worried that their software test wasn't adequate so they started testing proprietary systems. The broke every single one of the 16 proprietary systems they tested initially and found a further 9 systems vulnerable in later testing. They were able to install malware and also found firewalls ineffective.
They reported this to the Department of Homeland Security’s Industrial Control Systems Cyber Emergency Response Team, I.C.S.-C.E.R.T. and didn't get much of a response.
