Back in the 1960s, the U.S. started vaccinating kids for measles. As expected, children stopped getting measles.

But something else happened.

Childhood deaths from all infectious diseases plummeted. Even deaths from diseases like pneumonia and diarrhea were cut by half.

“So it’s really been a mystery — why do children stop dying at such high rates from all these different infections following introduction of the measles vaccine,” says Michael Mina, a postdoc in biology at Princeton University and a medical student at Emory University.

Like many viruses, measles is known to suppress the immune system for a few weeks after an infection. But previous studies in monkeys have suggested that measles takes this suppression to a whole new level: It erases immune protection to other diseases, Mina says.

Happy Smallpox Eradication Day

rageofthedogstar:

Today’s a good day for sharing one of my favorite essays:

It was in Ancient Egypt, where it attacked slave and pharaoh alike. In Rome, it effortlessly decimated armies. It killed in Syria. It killed in Moscow. In India, five million dead. It killed a thousand Europeans every day in the 18th century. It killed more than fifty million Native Americans. From the Peloponnesian War to the Civil War, it slew more soldiers and civilians than any weapon, any soldier, any army (Not that this stopped the most foolish and empty souls from attempting to harness the demon as a weapon against their enemies).

Cultures grew and faltered, and it remained. Empires rose and fell, and it thrived. Ideologies waxed and waned, but it did not care. Kill. Maim. Spread. An ancient, mad god, hidden from view, that could not be fought, could not be confronted, could not even be comprehended.

35 years ago, on December 9th, 1979, humanity declared victory.

This one evil, the horror from beyond memory, the monster that took 500 million people from this world – was destroyed.

You are a member of the species that did that. Never forget what we are capable of, when we band together and declare battle on what is broken in the world.

December 9th was when it was first declared eradicated by a group of scientists. Their conclusion was endorsed by the WHO on May 8th, 35 years ago today.

Happy Smallpox Eradication Day, everyone! [stims excitedly]

It’s funny how science fiction universes so often treat humans as a boring, default everyman species or even the weakest and dumbest.

I want to see a sci fi universe where we’re actually considered one of the more hideous and terrifying species.

How do we know our saliva and skin oils wouldn’t be ultra-corrosive to most other sapient races? What if we actually have the strongest vocal chords and can paralyze or kill the inhabitants of other worlds just by screaming at them? What if most sentient life in the universe turns out to be vegetable-like and lives in fear of us rare “animal” races who can move so quickly and chew shit up with our teeth?

Like that old story “they’re made of meat,” only we’re scarier.

HOLY SHIT THEY EAT CAPSAICIN FOR FUN

YOU GUYS I HEARD A HUMAN ONCE ATE AN AIRPLANE.

A HUMAN CAN KEEP FIGHTING FOR HOURS EVEN AFTER YOU SHOOT IT

humans are a proud warrior race with a pantheon of bloody gods: Ram-Bo, Schwarzenegger, etc.

REMOVING A LIMB WILL NOT FATALLY INCAPACITATE HUMANS: ALWAYS DESTROY THE HEAD.

WARNING: HUMANS CAN DETECT YOU EVEN AT NIGHT BY TRACKING VIBRATIONS THROUGH THE ATMOSPHERE

WARNING: HUMANS CAN REPRODUCE AT A RATE OF 1 PER SPACEYEAR. DESTROY INFESTATIONS IMMEDIATELY

THE HUMAN MOUTH HAS OVER THIRTY OUTCROPS OF BONE AND POWERFUL JAW MUSCLES.

HUMAN BITES CAN BE FATALLY INFECTIOUS EVEN TO OTHER HUMANS

WARNING: HUMANS CAN AND WILL USE IMPROVISED WEAPONS. SEE CLASSIFIED DATA LABELED J. CHAN.

HUMANS CAN PROJECT BIOWEAPONS FROM ALMOST EVERY ORIFICE ON THEIR BODY. DO NOT INHALE

OH GOD THE HUMANS FIGURED OUT DOOR HANDLES OH GOD OH GOD

 

prokopetz:

More seriously, humans do have a number of advantages even among Terrestrial life. Our endurance, shock resistance, and ability to recover from injury is absurdly high compared to almost any other animal. We often use the phrase “healthy as a horse” to connote heartiness – but compared to a human, a horse is as fragile as spun glass. There’s mounting evidence that our primitive ancestors would hunt large prey simply by following it at a walking pace, without sleep or rest, until it died of exhaustion; it’s called pursuit predation. Basically, we’re the Terminator.

(The only other animal that can sort of keep up with us? Dogs. That’s why we use them for hunting. And even then, it’s only “sort of”.)

Now extrapolate that to a galaxy in which most sapient life did not evolve from hyper-specialised pursuit predators:

  • Our strength and speed is nothing to write home about, but we don’t need to overpower or outrun you. We just need to outlast you – and by any other species’ standards, we just plain don’t get tired.
  • Where a simple broken leg will cause most species to go into shock and die, we can recover from virtually any injury that’s not immediately fatal. Even traumatic dismemberment isn’t necessarily a career-ending injury for a human.
  • We heal from injuries with extreme rapidity, recovering in weeks from wounds that would take others months or years to heal. The results aren’t pretty – humans have hyperactive scar tissue, among our other survival-oriented traits – but they’re highly functional.
  • Speaking of scarring, look at our medical science. We developed surgery centuries before developing even the most rudimentary anesthetics or life support. In extermis, humans have been known to perform surgery on themselves – and survive. Thanks to our extreme heartiness, we regard as routine medical procedures what most other species would regard as inventive forms of murder. We even perform radical surgery on ourselves for purely cosmetic reasons.

In essence, we’d be Space Orcs.

 

friendlytroll:

Our jaws have too many TEETH in them, so we developed a way to WELD METAL TO OUR TEETH and FORCE THE BONES IN OUR JAW to restructure over the course of years to fit them back into shape, and then we continue to wear metal in out mouths to keep them in place. 

We formed cohabitative relationships with tiny mammals and insects we keep at bay from bothering us by death, often using little analouge traps. 

And by god, we will eat anything. 

 

siderealsandman:

  • We use borderline toxic peppers to season our food. 
  • We expose ourselves to potentially lethal solar radiation in the pursuit of darkening our skin. 
  • We risk hearing loss for the opportunity to see our favorite musicians live. 
  • We have a game where two people get into an enclosed area and hit each other until time runs out/one of them pass out
  • We willingly jump out of planes with only a flimsy piece of cloth to prevent us from splattering against the ground. 
  • Our response to natural disasters is to just rebuild our buildings in the exact same places. 
  • We climb mountains and risk freezing to death for bragging rights
  • We invented dogs. We took our one time predators and completely domesticated them. 
  • On a planet full of lions, tigers and bears, we managed to advance further and faster than any other species on the planet. 

Klingons and Krogan and Orcs ain’t got shit on us

 

moniquill:

We drink ethanol (in concentrations high enough to be used as an effective as microbicide or a solvent!) for the express purpose of achieving blood toxicity and disrupting normal brain function… AS A RECREATIONAL ACTIVITY!

On the same subject, we also deliberately incinerate assorted substances and then inhale the particulate-heavy smoke and vapor resulting for the same effect. EVEN IN THE FACE OF SAID SUBSTANCES BEING CARCINOGENIC, BECAUSE WE JUST DON’T GIVE A FUCK.

 

therobotmonster:

Humans do not have biological castes. Kill their commander and another will take its place. Soldiers left alone on a planet will start farming and manufacturing to survive. Farmers and manufacturers will take up arms and kill you if pressed. Just because two humans look different doesn’t mean they cannot do each other’s jobs.

Breeding does not kill them. A single human can mate dozens or hundreds of times in a lifetime. They often do so as recreation. Xenobiology team six believes they do not have a mating season but this is too strange to be true.

Their appendages are not designed for hitting, so they developed special training to make them very good at hitting anyhow. 

The proteins making up their bodies are toxic and cause prion disease. Do not touch anything humans have touched. Do not consume earth foods. Fire does not adequately remove this contamination.

Humans perceive sixteen times the colors we do. Do not hide in bushes or vines from humans. They can distinguish your pelt from the foliage with ease.

We tried venting waste gas into the tunnels to kill the humans when they attacked. Turns out they breathe it. 

Everything on their planet came from a single biological strain. They developed comprehensive genetics BEFORE they developed space travel. 

They lack radio receptors and cannot be brought into compliance with right-thought simply by broadcasting to them. Even after we learned how to translate it into sound-waves one of their hatchlings drove the Great Authority mad by responding to every demand with a single question: “Why?”

 

silentstep:

#an individual human being is actually a microbiome in its own right—you are dealing with a legion each time you approach them     #they carry pathological agents inside their deep tissues and this is advantageous to their health     #one of the most widespread and resilient viruses on their planet is treated as mildly hazardous—even though it causes     #massive disruption to the body’s homeostasis     #(their young offspring endure multiple rhinovirus infections EACH YEAR yet they seem unperturbed by this)     #they have developed such long lifespans that now their primary threat is their own body’s degeneration     #humanity has literally figured out how to survive so long that their body gives out under them     #and they are not satisfied with that     #stupid willful vengeful survivalists who treat mortality like a challenge

Last year, people came up with some pretty great #ScienceValentines – let’s keep that rolling! How would you express your love for that special scientist in your life? Tweet @nprscience or message me, and I’ll collect the best ones.

(Bonus points if you can somehow incorporate landing on a comet)

Our bond is so strong, it don’t need oxytocin.
We’re woven together like a corpus callosum.
The love we impart, though it’s felt in our heart,
Is more of a limbic-type notion.

Penn & Teller kill the anti-vaccination argument in just over a minute.

This is why Penn & Teller are personal heroes

Probably the educational comic I’ve had to link to most is The Facts in The Case of Dr. Andrew Wakefield, by Darryl Cunningham, which is a total deconstruction of the bullshit that STARTED this whole idea.  It’s a fascinating read!

The “vaccines causes autism” lie was research sponsored by a company wanting to discredit their competitors (you know, the Big Pharma anti-vaxxers are so het up over), issued horribly painful, invasive procedures on children against guidelines, and was generally Very Bad Science that did NOT actually care about the well-being of children.

However, it plays into people’s fears about autism, science, and vaccines, and so people risk the health of CHILDREN AROUND THEM to satisfy their completely irrational fears. (This is why the “they’re just trying to protect their children!” argument holds no water with me.  You want to protect children?  You ain’t doing it by purposely denying vaccinations to your healthy child, thereby exposing immune-weakened kids, the ones who really CAN’T get vaccinated, to possibly fatal, crippling diseases.  You’re sacrificing other people’s children FOR YOUR SELFISH DESIRES.  You fucking prick.)

Despite being taken down and proven wrong again and again, people continue to BELIEVE this bullshit because it FEELS real, because it’s been around so long it MUST be true.  They knew this autistic kid once who became autistic after their vaccinations, so correlation MUST be causation, and also autism is totally worse than fucking measles. (Cluebat, people: it ain’t.  Not even CLOSE.)

Let’s stop HIV in New York City

  • If you are HIV-negative, PEP and PrEP can help you stay that way.
  • If you are HIV-positive, PEP and PrEP can help protect your partners.

 

Daily PrEP

PrEP is a daily pill that can help keep you HIV-negative as long as you take it every day.

  • Ask your doctor if PrEP (Pre-exposure Prophylaxis) may be right for you.
  • Condoms give you additional protection against HIV, other sexually transmitted infections, and unintended pregnancy.

 

Emergency PEP

If you are HIV-negative and think you were exposed to HIV, immediately go to a clinic or emergency room and ask for PEP (Post-exposure  Prophylaxis).

  • PEP can stop HIV if started within 36 hours of exposure.
  • You continue taking PEP for 28 days.

Many insurance plans including Medicaid cover PEP and PrEP. Assistance may be available if you are uninsured. Visit NYC Health’s website to find out where to get PrEP or PEP in New York City.

This is such a giant step that barely any people know about it seems, so amazing to see progress in the treatment of HIV

I honestly thought this might be exaggeration but the CDC says that PrEP is 92% effective. Damn. Damn.

reblogging because this deserves waaaay more attention D:
