Q:My dad is a cancer researcher and he knows better than anyone that cancer is a natural human function that can never be completely eradicated. Even if our bodies had the ability to live forever, everyone would eventually die of cancerous causes. This isn't to say that we shouldn't stop trying, healing whoever possible, and searching, but it is a fact of science and life. Ps there was no need to be so rude to whomever posted that picture.
Yes, it is a natural human phenomenon. I said as such. But we have more effective treatments for it, don’t we? We’re able to eradicate cancerous cells in an increased percentage of individuals, aren’t we? In maybe not my lifetime, but the next generations’, I think we’ll have effective treatments for most every variety of cancer (if not disease in general).
It can’t be eradicated like a disease, but we can make it so that it’s a completely treatable condition.
I have very little patience for people who have the attitude that the human condition is to be completely helpless to the throes of nature when in reality we can accomplish so much.
I love science and I love progress and I get very passionate about the potential of future advancements, and the attitude that “oh we’ll always be a slave to this certain condition” does nothing but hold people back.
For those who are fighting cancer or supporting their loved one’s fight, all the best. There are new and fascinating weapons of war to help with your battles. The war for our species, however, will never be won. Cells cannot replicate perfectly forever, no cancer researcher ever thought eradication was ever possible, only President Nixon did.
Meanwhile in other parts of the world outside the United States’ billion dollar fixation on cancer, hundreds of thousands of lives are lost to completely preventable diseases annually. Currently, thousands of people are scrambling to contain an ebola outbreak that’s claimed more lives than the virus previously has in all of its history. Prediction by WHO is 20,000 by the end of November. Why isn’t there an Ebola vaccine, just like smallpox? There are complications. However, prior to the rush the present outbreak brought on the main obstacle was simple economics.
“Pharmaceutical companies have little incentive to pour research and development dollars into curing a disease that surfaces sporadically in low-income, African countries. They aren’t likely to see a large pay-off at the end — and could stand to lose money.”
This is simply one example among hundreds. Of course we can focus on the medical treatment of more than one thing at a time. But when cancer is vastly economically dominating in western countries, it is not a “put down” to keep in mind the scientific fact that cancer cannot be eradicated. It is misleading to make campaigns like a “war on cancer” or “cure for cancer”. When in fact, there are many diseases that can be cured or vaccinated against that aren’t.
Rabies & Hydrophobia
A symptom in furious rabies is an extreme aversion to liquid. Infected animals are initially conscious and can express a desire for hydration. However any kind of swallowing, possibly the mere suggestion to drink, will induce excruciatingly painful muscle spasms of the throat. Victims are quickly conditioned with an aversion response, including their own saliva. The virus reproduces in the salivary glands, so this symptom increases the transmission rate through bites. [X]

The maps that track death and disease across the world aren’t usually uplifting. But a new map from the Pulitzer Center tells a different kind of story, one that actually marks a set of enormous, but quiet, wins for decreasing the rate of childhood mortality.
Hey Shark Week, sharks are cool, but they’re not even close to being the deadliest animal.

Every time I hear about how many people mosquitoes have killed since the dawn of man, I shake my head in disbelief. According to Vsauce, roughly HALF of all people who have ever died have died from mosquito bites!
Although it’s not really the mosquito that’s killing people, but the protozoan parasites Plasmodium falciparum and/or vivax. Vicious, bloodthirsty Plasmodia!! Does your bloodlust know no bounds?
I’d also recommend listening to this recent Radiolab episode, “KILL ‘EM ALL”, which asks the question if you could kill all the mosquitoes on Earth, would you? It’s embedded below:

Northwestern Medicine scientists are continuing to unravel the molecular changes that underlie one of the world’s deadliest and most infamous respiratory infections.
When the bacterium Yersinia pestis enters the lungs, it causes pneumonic plague, a disease that is 100 percent fatal if untreated. The way in which Y. pestis evades the immune system and kills people in a matter of days has largely confounded scientists, until now.
Following a 2007 study demonstrating that the presence of a protein called the plasminogen activator protease (Pla) is required for Y. pestis to live inside the lungs, Wyndham Lathem, PhD, assistant professor in Microbiology-Immunology, has found what role Pla plays during disease.
The activator shuts down a molecule, Fas ligand (FasL), which stimulates a form ofprogrammed cell death known as apoptosis. The result is a disrupted immune response during infection. This allows Y. pestis to overwhelm the lungs, causing death.
"This is the first time anyone has shown how bacteria can subvert apoptotic cell death by directly destroying Fas ligand," said Lathem, a member of the Center for Genetic Medicine and Interdepartmental Immunobiology Center.
The findings were published April 9 in Cell Host & Microbe.
To study its effects, scientists added Pla to glass slides with various fluorescently-tagged proteins. If the protease showed an affinity for a specific protein, it would chew off pieces, making it appear less florescent when viewed under a microscope.
"We knew that Pla must be chopping up host proteins in some manner and we looked to discover exactly what proteins were being affected," said first author Adam Caulfield, a research associate in Lathem’s lab.
"As we reviewed possible hits, the ‘aha moment’ came when we saw Fas ligand on the list of affected proteins, because we know Fas is an integral receptor for controlling cell death," said Lathem. "The process of Pla degrading Fas ligand effectively prevents the lungs from being able to clear the infection."
After verifying their findings using cell cultures, Lathem conducted preclinical tests using mice, arriving at the same conclusion.
"Now that we have identified this as a method by which plague bacteria can manipulate the immune system, we have something to look for when studying other respiratory infections," Lathem said. "This could be a common feature, where we see other bacteria manipulating cell death pathways by altering Fas signaling."
Pneumonic plague is unique in that it is the only type of plague with an ability to spread from person to person. It is treatable if caught early, but after 24 hours, antibiotics are rendered useless.
Lathem believes that a restoration of Fas signaling may give antibiotics more time to work, and scientists in his lab are exploring that possibility. They will also be looking at different bacterial infections to see if any manipulate cell death by altering Fas signaling in a similar manner.

The first transparent 3D-printed skull has been successfully implanted.Three months ago, surgeons in Holland implanted a transparent plastic skull in a woman whose skull has never stopped growing. Incredibly, the rare bone disease that was wrecking her vision and destroying her life has been been bested by a simple 3D printer. The team of surgeons, led by Dr. Bon Verweij at the University Medical Center in Utrecht, expect her new skull to last indefinitely, opening up new vistas for cranial transformation.

Smart Solution To Stop Needle Reuse Wins Design Impact Award
Healthcare providers reusing unsterilized syringes and needles cause more than 1.3 million infections around the world every year, according to the World Health Organization. Ignorance of the dangers and a lack of supplies means that the average syringe is reused four times in the developing world, says advocacy and education charity Safepoint.
The problem, which spreads bloodborne pathogens like hepatitis and
AIDSHIV (h/t and good catch to sexeducationforprudes), led healthcare designer David Swann and his team at the University of Huddersfield in the United Kingdom to come up with a simple and cheap visual aid.
They created a syringe coated with a color-changing dye that turns red when exposed to carbon dioxide. The so-called A Behavior-Changing (ABC) syringe is stored in a nitrogen-filled pack and starts changing color only when the pack is punctured or the syringe is removed.
