Are crows the ultimate problem solvers? - Inside the Animal Mind: Episode 2 - BBC Two

Yes, I think they might be…

In this BBC special, Dr. Alex Taylor has set up an eight-step puzzle to try and stump one of the smartest crows he’s seen in captivity. They describe the puzzle as “one of the most complex tests of the animal mind ever.”

This isn’t the first time crows’ intelligence has been tested, either. Along with being problem solvers, these animals have an eerie tendency towards complex human-like memory skills. Through several different studies, we’ve learned that crows can recognize faces, communicate details of an event to each other and even avoid places they recognize as dangerous.

Giant virus resurrected from 30,000-year-old ice (Nature News)

Scientists have revived a giant virus that was buried in Siberian ice for 30,000 years — and it is still infectious. Its targets are amoebae, but the researchers suggest that as Earth’s ice melts, this could trigger the return of other ancient viruses, with potential risks for human health.

The newly thawed virus is the biggest one ever found. At 1.5 micrometres long, it is comparable in size to a small bacterium. Evolutionary biologists Jean-Michel Claverie and Chantal Abergel, the husband-and-wife team at Aix-Marseille University in France who led the work, named it Pithovirus sibericum, inspired by the Greek word ‘pithos’ for the large container used by the ancient Greeks to store wine and food. “We’re French, so we had to put wine in the story,” says Claverie. The results are published in Proceedings of the National Academy of Sciences1

Larger than some bacteria, this virus — seen in a cross-section under a transmission electron microscope — was still able to infect amoebae despite having spent 30 millennia in a frozen state. Julia Bartoli & Chantal Abergel; Information Génomique et Structurale, CNRS-AMU

Depression detectable in the blood: Platelet serotonin transporter function

Researchers at the MedUni Vienna have now used functional magnetic resonance imaging of the brain and pharmacological investigations to demonstrate that there is a close relationship between the speed of the serotonin uptake in blood platelets and the function of a depression network in the brain.

"This is the first study that has been able to predict the activity of a major depression network in the brain using a blood test. While blood tests for mental illnesses have until recently been regarded as impossible, this study clearly shows that a blood test is possible in principle for diagnosing depression and could become reality in the not too distant future," explains study leader Lukas Pezawas from the Department of Biological Psychiatry at the University Department of Psychiatry and Psychotherapy within the MedUni Vienna. This result means that the diagnosis of depression through blood tests could become reality in the not too distant future.

"A psychologist at a girl’s college asked the members of his class to compliment any girl wearing red. Within a week the cafeteria was a blaze of red. None of the girls were aware of being influenced, although they did notice that the atmosphere was more friendly. A class at the University of Minnesota is reported to have conditioned their psychology professor a week after he told them about learning without awareness. Every time he moved toward the right side of the room, they paid more attention and laughed more uproariously at his jokes, until apparently they were able to condition him right out the door."

no way

i can’t decide if this is figuratively or literally unbelievable

Literally look at this misdirecting shit. Look at it. 

Look at how they organize the y-axis in descending order in order to make the chart go DOWN, assuming people wont look at it for two seconds and assume that enrollment is falling when its actually nearly doubled since its first estimation. 

This is the kind of shit that Fox News pulls to lie to its viewers in plain sight. This is how desperate they are to discredit the ACA as unpopular and unwanted when its actually the opposite. 

Wow

Incredible, shameless duplicity.

"Wall Street elites, corporate profiteers, and inheritors of multibillion-dollar fortunes are trying to divert our attention from their oligarchic greed by spending lots of money on PR campaigns, front groups, and politicians to tell us that “Big Government” is our problem. I was born at night, but not last night! The ones knocking down the middle class and holding down the poor today are those same elites, profiteers, and heirs. The corporate media won’t talk much about this reality, but a growing majority see it and are participating in a spreading rebellion against it. Because, after all, they’re experiencing the abuse."

America’s ongoing rebellion for fairness and justice (via smdxn)

The Middle Class needs to identify the enemy. “Divide and conquer” is being used on the millions of working classes to keep them distracted from the real welfare queens addicted to government handouts: Wall St, banks, oligarch heirs and the 1%. These mega-wealthy ‘takers’ are the ones dependent on government. That is why they are buying all the elections and politicians.

Antibiotic Resistance Is Now Rife across the Globe

Dangerous antibiotic-resistant bacteria and other pathogens have now emerged in every part of the world and threaten to roll back a century of medical advances. That’s the message from the World Health Organization in its first global report on this growing problem, which draws on drug-resistance data in 114 countries.
 
“A post antibiotic-era—in which common infections and minor injuries can kill—far from being an apocalyptic fantasy, is instead a very real possibility for the 21st century,” wrote Keiji Fukuda, WHO’s assistant director general for Health Security, in an introduction to the report. The crisis is the fruit of several decades of overreliance on the drugs and careless prescribing practices as well as routine use of the medicines in the rearing of livestock, the report noted.
 
Antibiotic resistance is putting patients in peril in both developing and developed countries, as bacteria responsible for an array of dangerous infections evolve resistance to the drugs that once vanquished them.
 
Gonorrhea, once well treated by antibiotics, is once again a major public health threat due to the emergence of new, resistant strains. Drugs that were once a last resort treatment for the sexually transmitted disease—which can lead to infertility, blindness and increased odds of HIV transmission if left untreated—are now the first-line treatment and are sometimes ineffective among patients in countries such as the U.K., Canada, Australia, France, Japan, Norway, South Africa, Slovenia and Sweden.
 
Drugs to treat Klebsiella pneumoniae—a common intestinal bacteria that can cause life-threatening infections in intensive care unit patients and newborns—no longer work in more than half of patients in some countries. And fluoroquinolones, drugs used to treat urinary tract infections, are also ineffective in more than half of sufferers in many parts of the world. Efforts to limit the spread of multidrug-resistant tuberculosis, malaria and HIV are also all under threat due to increasing bacterial resistance.
 
Although the development of resistance is to be expected over time, overuse of the drugs has accelerated the process by supplying additional selective pressure, noted the report, which was authored by an extensive team of researchers with WHO. And there are few drugs to replace the ones that are now ineffective: The last entirely new class of antibacterial drugs was discovered 27 years ago, according to the report.

The government does everything it can to contain disabled people in poverty (ie. giving us the BARE MINIMUM to live off of, cutting off our benefits if there are more than $2000 in our accounts, allowing businesses to pay us sub-human wages) and yet the government will spread horror stories that we’re phonies who abuse the system, and they’ll talk about us like we’re lazy burdens who won’t do anything to get off government assistance. 

How fucked up is that?

Michaela DePrince 

 THIS IS SO FUCKING IMPORTANT!

black ballerina excellence

So gorgeous and elegant

Why is this important? i see a girl doing ballet, stop outlining difference, its important we just admire the skills, and afore mentioned ellegance

First of all shut the fuck up and have several seats 

and heres why in Michaela’s own words what she had to go through being BLACK and still goes through.

When she was around 8 and rehearsing for The Nutcracker, just a few days before the performance she was told, “I’m sorry, you can’t do it. America’s not ready for a black girl ballerina.”

For Michaela, “to say this to an 8-year-old is just devastating. It was terrible.”

When she was 9, a teacher told her mother: “I don’t like to put money into black dancers because they grow up and end up having big boobs and big hips.”

The dancer looked down at her petite figure and protested, “I don’t have boobs. I don’t get it.”

Instead of getting her down, “It makes me more determined,” she said. “Because I’ve been through so much, I know now that I can make it and I can help other kids who have been in really bad situations realize that they can make it too.”

This is why it is important, for little Black girls to see a black ballerina made it despite being discriminated against because of her skin color!!! 

We don’t outline differences. We acknowledge our greatness because the world doesn’t. What I do find important, however, is your need to work on your spelling and sentence structure. Get to it.
