Not really news (though some of it was news to me) - but some fascinating physiological facts from the Wikipedia article on cats:
[i]
"As cats are familiar and easily kept animals, their physiology has been particularly well studied; it generally resembles that of other carnivorous mammals but displays several unusual features probably attributable to cats' descent from desert-dwelling species. For instance, cats are able to tolerate quite high temperatures: Humans generally start to feel uncomfortable when their skin temperature passes about 38 °C (100 °F), but cats show no discomfort until their skin reaches around 52 °C (126 °F), and can tolerate temperatures of up to 56 °C (133 °F) if they have access to water.

...Cats' feces are comparatively dry and their urine is highly concentrated, both of which are adaptations that allow cats to retain as much fluid as possible. Their kidneys are so efficient that cats can survive on a diet consisting only of meat, with no additional water, and can even rehydrate by drinking seawater."
[/i]
Another interesting factoid from the same page:
[i]
A group of cats is referred to as a "clowder" or a "glaring".
[/i]
I did not know that. :o

A final interesting factoid: The 2nd part of the Linnean species name for wildcats (and domestic cats, though there the S. part is often dropped to yield just [i]F. Catus[/i]), [i]Felis Silvestris[/i], does not derive from the Latin word for "forest" as is generally supposed, but rather is an homage to the famous cat from the Warner Brothers [i]Sylvester and Tweety[/i] cartoons.

[spoiler]OK, I admit I made up that last bit. Interestingly though, there is such an homage involved - but it's [url=http://en.wikipedia.org/wiki/Sylvester_%28Looney_Tunes%29]the other way around[/url].[/spoiler]

My sister's "grey eminence" cat (think Russian-blue-looking, but this was a delightful mutt who ended up with an elegant coat) used to love to sit on the hearth so close to the fire that his fur was literally too hot to touch without significant pain. Obviosuly fur's insulative value works both ways; our main concern was a stray ember somehow getting through/over the steel mesh curtain. Never happened, thankfully.

I was most interested to read about the able-to-drink-seawater aspect of the physiology - apparently humankind's ancestors were sufficiently good at finding fresh water that we never underwent selection for such an adaptation.

[QUOTE]The findings come after scientists studied small fragments of the Chelyabinsk meteor that made it through the massive explosion in Earth's atmosphere and landed on the ground. Lead researcher Shin Ozawa, of Japan's University of Tohoku, and his team found a rare mineral called jadeite in glass-like veins inside the samples. That mineral could only be produced under massive pressure and heat, such as that from an impact with another asteroid. By studying the shape and structure of the jadeite crystals, they were able to estimate the size, temperature, and duration of the impact. The results were published this week in Scientific Reports. Previously, scientists had used video footage to determine the path of the meteor to Earth, and analysis of the impact found it to be the second largest explosion in recorded history.[/QUOTE]

[URL="http://ireport.cnn.com/docs/DOC-1137095"]Giant asteroid possibly on collision course with Earth[/URL]

[QUOTE] If astronomers are right, all life on this planet could be extinguished in less than 30 years from now. Scientists at NASA's Jet Propulsion Laboratory have detected a large object the size of Manhattan possibly on a collision course with Earth. Using their Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE), the 10-mile wide object was found approximately 51 million miles from Earth. Scientists believe that during a close encounter with Mars, the asteroid was nudged slightly off its usual orbit and may currently be on a high speed collision course with our fragile planet.

The asteroid is calculated to have a potentially lethal encounter with the Earth on March 35, 2041. Astronomers have placed the odds of an impact at 1 in 2.04, which is by far the most unprecedented risk ever faced to humanity, let alone from asteroids. Such an impact could potentially end civilization as we know it.

More information will be posted here as the story develops.[/QUOTE]

New wind turbine design
 
[url]http://www.gizmag.com/the-archimedes-liam-f1-urban-wind-turbine/32263/[/url]

[QUOTE]Although it's getting increasingly common to see solar panels on the roofs of homes, [URL="http://www.gizmag.com/secret-energy-wind-turbine/14299/"]household wind turbines[/URL] are still a fairly rare sight. If Rotterdam-based tech firm The Archimedes has its way, however, that will soon change. Today the company officially introduced its Liam F1 Urban Wind Turbine, which is said to have an energy yield that is "80 percent of the maximum that is theoretically feasible." That's quite the assertion, given that most conventional wind turbines average around 25 to 50 percent.
The 75-kg (165-lb) 1.5-meter (5-ft)-wide Liam obviously doesn't look much like a typical turbine. It draws on the form of the nautilus shell, and the screw pump invented by ancient Greek mathematician Archimedes of Syracuse.
That form factor reportedly results in minimal mechanical resistance, allowing it to spin very freely [I]and[/I] to operate quietly – blade noise is one of the common complaints regarding rooftop wind turbines. Additionally, the design is claimed to keep it always pointing into the wind for maximum yield.

[B]Scientists condemn 'crazy, dangerous' creation of deadly airborne flu virus[/B]

[QUOTE]Scientists have created a life-threatening virus that closely resembles the 1918 Spanish flu strain that killed an estimated 50m people in an experiment labelled as "crazy" by opponents.
US researchers said the experiments were crucial for understanding the public health risk posed by viruses currently circulating in wild birds, but critics condemned the studies as dangerous and called on funders to stop the work.
Scientists at the University of Wisconsin-Madison used a technique called reverse genetics to build the virus from fragments of wild bird flu strains. They then mutated the virus to make it airborne to spread more easily from one animal to another.
"The work they are doing is absolutely crazy. The whole thing is exceedingly dangerous," said Lord May, the former president of the Royal Society and one time chief science adviser to the UK government. "Yes, there is a danger, but it's not arising form the viruses out there in the animals, it's arising from the labs of grossly ambitious people."[/QUOTE]Press article: [URL]http://www.theguardian.com/science/2014/jun/11/crazy-dangerous-creation-deadly-airborne-flu-virus[/URL]

Well, that is the idea! Create some panic following some common flu. Lots of money invested (read: stolen) to create a drug which is good for nothing. Its effectiveness is still disputed, but many agree that is placebo, or even worse, as the placebo doesn't have adverse effects. But the new drug is cheap to produce, so huge quantities were produced and partially sold for lots of money. People get clever and don't buy the drug anymore. Then, invest more money to create a virus which fits to the drug you have. Convince people to buy your (non movable) drug stocks. Profit!

Ebola outbreak
 
"Drastic action" is needed to contain the spread of deadly Ebola in West Africa, according to the World Health Organization (WHO).
Nearly 400 people have died in the outbreak which started in Guinea and has spread to neighbouring Sierra Leone and Liberia.
It is the largest outbreak in terms of cases, deaths and geographical spread.
The WHO said it was "gravely concerned" and there was potential for "further international spread".
The outbreak started four months ago and is continuing to spread.
So far there have been more than 600 cases and around 60% of those infected with the virus have died.
Ebola, a haemorrhagic fever, has no cure and is spread by contact with the fluids of infected people or animals, such as urine, sweat and blood.

On this forum alone, we already had discussions about a child prodigy who found a cure for cancer, or another one who built cell phone battery prototypes that would run ten times longer... Some ask how did this get in the news, others insist that if it wasn't true it wouldn't have been in the news.

Who is to blame? The media is finely tuned to the public demand of "freak news" and "freak shows" -- these generate clicks and sell ads. The chicken and the egg. It is probably important to remember that these articles have entertainment value only (a.k.a. human angle), not scientific, and as such 1) are not vetted deep enough (there is no liability, there will be no need for retraction, or better yet, if public will get too heated, there is an opportunity to write five more follow-up articles!), 2) are written by the same people who write about fishing records or, say, a cow that wondered in the middle of a highway (and you get occasional gems like 'The largest know prime has 11 digits'), 3) are forgotten tomorrow.

From the article:
[i]
Of course, the idea that “you only use 10% of your brain” is, indeed, 100% bogus. Why has this myth persisted for so long, and when is it finally going to die?
[/i]
Um, "when it stops working as a vehicle to sell pop entertainment"?

I would guess that the persistence of this (and other) myths and delusions is strong evidence, however, that most folks use less than 10% of their reasoning faculties in terms of critical thinking. There are powerful vested interests helping to keep this so, of various stripes: religious, political, commercial, &c.


[QUOTE=Batalov;379161]and you get occasional gems like 'The largest know prime has 11 digits'[/QUOTE]

In a suitably large base with a correspondingly large digit set, that is indubitably true. (Admit it, you just H8 child prodigies!)

Didn't read beyond the above blurb (yet), but isn't the "repeated kicks in the same direction" bit an example of precisely such exploitation? Just keep kicking to one side, watch the goalie overthink himself and start diving the other way, "because I'm due for a heads on the next flip".

It should say that only 8.2% of human DNA is evolutionarily conserved. That approach omits functional DNA that has recently changed (eg the bits that make us human instead of apes). But I've no idea how much DNA that might be.

then in theory since 8.2/0.1 = 82 82% is the most amount of genetics that should be related to the brain.

[url=www.nytimes.com/2014/09/02/health/low-carb-vs-low-fat-diet.html]A Call for a Low-Carb Diet That Embraces Fat[/url] | NYT
[quote]People who avoid carbohydrates and eat more fat, even saturated fat, lose more body fat and have fewer cardiovascular risks than people who follow the low-fat diet that health authorities have favored for decades, a major new study shows.

The findings are unlikely to be the final salvo in what has been a long and often contentious debate about what foods are best to eat for weight loss and overall health. The notion that dietary fat is harmful, particularly saturated fat, arose decades ago from comparisons of disease rates among large national populations. [i][EWM: It was later shown that the studies in question cherry-picked data and the "benefits" disappeared when the original data sets were used, but hey, never let facts get in the way of a good marketing campaign. Right, Dr. Atkins?][/i]

But more recent clinical studies in which individuals and their diets were assessed over time have produced a more complex picture. Some have provided strong evidence that people can sharply reduce their heart disease risk by eating fewer carbohydrates and more dietary fat, with the exception of trans fats. The new findings suggest that this strategy more effectively reduces body fat and also lowers overall weight.

The new study was financed by the National Institutes of Health and published in the Annals of Internal Medicine. It included a racially diverse group of 150 men and women — a rarity in clinical nutrition studies — who were assigned to follow diets for one year that limited either the amount of carbs or fat that they could eat, but not overall calories.

“To my knowledge, this is one of the first long-term trials [i][EWM: besides the long-term trial known as "human evolutionary history", that is][/i] that’s given these diets without calorie restrictions,” said Dariush Mozaffarian, the dean of the Friedman School of Nutrition Science and Policy at Tufts University, who was not involved in the new study.[/quote]
Of course rampant sedentism also factors into the picture, but the fact that the effects manifest so strongly even in "soft" modern cohorts is striking.

The worst news for the low-fat acolytes:
[quote]While the low-fat group did lose weight, they appeared to lose more muscle than fat.

“They actually lost lean muscle mass, which is a bad thing,” Dr. Mozaffarian said. “Your balance of lean mass versus fat mass is much more important than weight. And that’s a very important finding that shows why the low-carb, high-fat group did so metabolically well.”[/quote]

[quote]The US military is set to join the battle against an enemy other than ISIS: the Ebola outbreak that has killed thousands in West Africa. President Obama is expected to outline what officials describe as a “scaled-up” response to the outbreak this week, reports the Wall Street Journal, which notes that while the chances of the disease spreading to the US are considered low, the chances of the virus mutating to become more infectious increase with every new human infection. There are currently eight US military service members working to contain the outbreak, and the stepped-up military involvement is expected to include much-needed logistical help, though not hospital ships, which officials fear could end up being swept by infection. Ellen Johnson Sirleaf, president of hard-hit Liberia, has appealed for American aid as the disease spreads exponentially, Reuters reports. “Without more direct help from your government, we will lose this battle against Ebola,” she wrote to Obama, warning that Ebola treatment centers are being forced to turn away patients and “at this rate, we will never break the transmission chain and the virus will overwhelm us.” In neighboring Sierra Leone, a fourth doctor has died of Ebola after a failed attempt to send her out of the country for treatment, reports the AP. The country, which was desperately short of doctors even before the outbreak, asked the World Health Organization for help evacuating Olivet Buck to Europe, but the request was declined.”[/quote]
But will we "follow the Ebola virus to the gates of hell"? Anything less sounds wishy-washy at this point.

The file itself is harmless, just a PDF, it can not infect your computer :smile: but the content of the file is dangerous for your brain. You better first finish the khanacademy math section first, with 100% mastered, then try to open the file. The author(s) use some differential math to try to model how the ebola virus (irrelevant, it could be about any other disease, he is just capitalizing on the ebola breakout, which is dishonest, in my opinion) spreads (or has spread).
Nothing important, nor easy to grasp.

Bug in Bash shell creates big security hole on anything with *nix in it

[QUOTE][URL="http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2014-6271"]The bug[/URL], discovered by [URL="http://stephane.chazelas.free.fr/"]Stephane Schazelas[/URL], is related to how Bash processes environmental variables passed by the operating system or by a program calling a Bash-based script. If Bash has been configured as the default system shell, it can be used by network–based attackers against servers and other Unix and Linux devices via Web requests, secure shell, telnet sessions, or other programs that use Bash to execute scripts.[/QUOTE]

Thanks to the miracle of open source software and dedicated volunteer programmers, the fix for that bug was pushed out to our systems (Ubuntu) before we even read the news.
