Sharks Do Get Cancer: Tumor Found in Great White
Scientists have known for more than 150 years that sharks get cancer. And yet the belief persists that the animals don’t suffer from the disease.
That misconception is promoted in part by those who sell shark cartilage, who claim that the substance will help cure cancer, said David Shiffman, a shark researcher and doctoral student at the University of Miami. But no studies have shown that shark cartilage is an effective treatment, and the demand for the material has helped decimate shark populations, researchers say: Humans kill about 100 million sharks per year, according to a March 2013 study (although many factors contribute to the killing of sharks, including demand for shark-fin soup).
Recently, researchers in Australia noticed a large tumor protruding from the mouth of a great white shark, as well as another mass on the head of a bronze whaler shark. The great white’s tumor measured 1 foot (30 centimeters) long and 1 foot wide, according to a study describing the tumors published online in November in the Journal of Fish Diseases.
"This was a very unusual sight as we have never before seen a [great] white shark with tumors," said Rachel Robbins, a study co-author and shark biologist at the Fox Shark Research Foundation, near Adelaide, in southern Australia. [Image Gallery: Great White Sharks]
In total, scientists have now documented tumors in at least 23 species of sharks, including the two in the new study, Robbins said. “The main take-home message from the study is that it adds to the growing evidence of tumor formation in sharks, contrary to popular belief that sharks do not suffer from such anomalies,” Robbins told LiveScience.
"Sharks get cancer," said Shiffman, who wasn’t involved in the study. "Even if they didn’t get cancer, eating shark products won’t cure cancer any more than me eating Michael Jordan would make me better at basketball."
The belief that shark cartilage can treat cancer diverts patients from effective treatments, according to a 2004 review in the journal Cancer Research. The demand for cartilage also fuels widespread fishing for sharks. One in six known species of sharks, rays and skates are considered threatened with extinction by the International Union for Conservation of Nature, an environmental group, Shiffman said.
It’s unknown what caused the tumors in the great white or bronzer shark. However, reports of cancerous tumors in marine animals, especially mammals, have steadily increased over the past 20 years, raising concerns that industrial pollutants or human activities may trigger the cancers, according to the study. Beluga whales have been recorded to suffer from cancer, and in areas near aluminum smelting plants, cancer is the second leading killer of the whales, the study noted. (source)
People are so fucking stupid. Eating an animal that’s immune to a disease will make you immune to that disease? Should I fucking eat my cat because it can’t get krohn’s disease and then I’ll be cured of krohn’s disease?
And then people wonder why I hate pseudoscience.
This makes me really sad.
The world’s most viewed TED Talk. In GIFs!
I just can’t reblog this enough. If I filled up my tumblr with just this it wouldn’t be enough. Most of all I wish I could tell my immediate family about this because they perpetuate me growing out of creativity -.-
If you haven’t seen this TED Talk, I highly recommend it.
One of the things I’ve really focused on as a parent is making sure my kids know that making lots of mistakes is the best way to learn something new. If you get something on the first try it might be exciting, but you haven’t really learned anything. This is definitely something I was not taught as a child, unfortunately, which made me averse to trying anything new out of a fear of failure. It’s taken me a long time to retrain my thoughts to not take errors as huge blows to my self-confidence.
My kids deserve better. All kids deserve better. ~JJ
If only they played this everyday when I was in public schools.
Members of Congress are living off food stamps for a week to protest Republican cuts. It’s a challenge for them, but GOP cuts would hurt millions of everyday Americans.
Why does this not have more publicity. This needs it!
Signal boosting this A) because it deserves to be seen by more people, and b) because I appreciate some members of Congress are actually willing to see what it’s like living on food stamps in order to make their point about how horrifying cutting food stamps would be.
News flash, regressives: people on food stamps do not load up on Snickers bars and filet mignon. They’re limited in what they can buy, and oftentimes, it’s not enough to get by on. Go on thinking these are entitlements that let minorities live lives of luxury, comfortable in the knowledge that you’ll never go hungry.
You privileged, elitist pricks.
Licia Ronzulli, member of the European Parliament, has been taking her daughter Vittoria to the Parliament sessions for two years now.
The second to last photo is my favorite I think. “Yes, mommy and I are in agreeance on this vote, thank you.”
Is no one else excited about how well-dressed she is???
Scary. Insane. Ridiculous. Invasive. Wrong. The Washington Post reports that the FBI has had the ability to secretly activate a computer’s camera “without triggering the light that lets users know it is recording” for years now. What in the hell is going on? What kind of world do we live in?
Marcus Thomas, the former assistant director of the FBI’s Operational Technology Division, told the Post that that sort of creepy spy laptop recording is “mainly” used in terrorism cases or the “most serious” of criminal investigations. That doesn’t really make it less crazy (or any better) since the very idea of the FBI being able to watch you through your computer is absolutely disturbing.
ah yeah i know someone who used to keep blu tac over the lens when they weren’t using it i figured it was a bit unecessary but maybe not
I have my laptop camera covered by a banana sticker and my 3DS camera with something I found stuck to an envelope
well time to tac over my cam since the US anti terrorist boy gang think its ok to police the entire globe
FBI watchin u watch porn while monitoring what porn ur watchin

States refusing to expand Medicaid under the Affordable Care Act will lose more than $35 billion collectively in federal funds by 2022, and cost their taxpaying citizens more. That’s from a new report from the Commonwealth Fund, Not expanding Medicaid is not a rational decision for any state. But there are some very big losers: Texas ($9.6 billion), Florida ($5 billion), Georgia ($2.9 billion), Virginia ($2.8 billion) and North Carolina ($2.6 billion). The citizens of those states will continue to “bear a significant share of the overall cost of the expansion through federal tax payments,” the report says, while they will “not enjoy any of the benefits.”
So red state residents are paying the federal taxes that help support Medicaid expansion everywhere but at home. More than that, they’re losing the community hospitals that they rely on for timely medical care, especially in emergencies.
All because the Republican governors of these states are afraid of the GOP presidential primary. They’re cowards who are hurting people for no good reason, because the GOP base is insane.
Dear President Obama,
I am Ju Hong, the “heckler” that interrupted your speech at the Betty Ong Center in San Francisco last week. I spoke up not out of disrespect, however, either for you or our country. No, I spoke up — and am writing to you now — to ask that you use your executive order to halt deportations for 11.5 million undocumented immigrant families.
My family came to the United States from South Korea when I was 11 years old. Like many immigrants, my mother brought me to this country to seek a better life for her children.
I graduated from UC Berkeley, and am now pursuing a Master’s degree in Public Administration at San Francisco State University. I have lived in America now for 13 years. I consider this country as my home. During my senior year in high school, however, I learned that my family had overstayed a tourist visa. We are undocumented immigrants.
As an American without papers, I was not able to get a job, obtain a driver’s license, or receive governmental financial aid. When my mother was sick and in severe pain, she did not visit a doctor because she cannot procure medical insurance. And when my family’s home was burglarized, she refused to call the police because she was afraid that our family would be turned over to immigration officials and deported.
Like many other undocumented immigrants, I was living in the shadows and living in fear of deportation. However, I have decided to speak out and stand up.
Immigration reform is not only a Latino issue, it’s also an Asian and Pacific Islander issue — in fact, it is a human rights issue. Currently, two million of the estimated 11.5 million undocumented immigrants in our country come from Asia. Under your administration, 250,000 undocumented Asian/Pacific Islander immigrants have been deported. While we only make up five percent of the country, we are disproportionately impacted by your immigration policies.
Last week, I was formally invited by White House staff to hear your remarks on immigration reform in San Francisco. As I stood in the stands behind you, I was hoping to hear about your plan to address the lives of 11 million undocumented people living in this country, like my family. And while you expressed your support for comprehensive immigration reform, you did not address how an average of 1,100 immigrants are deported every single day under your administration. You did not address how you deported 205,000 parents of U.S. citizens in the last two years. You did not address how, because of your administration’s record number of deportations—nearly two million immigrants in five years, a record—families are being torn apart: spouses are being separated from each other, parents are being separated from their children, and our brothers and sisters are being separated from one another. You did not to address how your administration would end the anti-immigration deportation programs like “Secure Communities." You’ve deported more people than any other president in the U.S. history.
Interestingly, you talked about Angel Island during your speech. What you did not mention, however, is that more people are detained every single day in detention today than were detained yearly at Angel Island. You recognized Angel Island as a dark period in Chinatown’s history, but you failed to recognize that more Asians and Pacific Islanders are in detention today than were in detention under the Chinese Exclusion Act. In fact, your administration detains up to 34,000 people per day, a record number of detainees in U.S. history.
Because you failed to address these issues, I was compelled to address the concerns of our community.
You claim that the President of the United States has no authority to stop the deportations. And yet, in June 2012, before the 2012 election, which you won with the help of Latino and Asian voters, you implemented Deferred Action for Childhood Arrivals. With the stroke of a pen, you dramatically changed the lives of hundreds of thousands of young people like me who can now live without the daily threat of deportation, and can legally work in this country for the first time in our lives.
I know that you support comprehensive immigration reform. But I also know that you have the power to stop the deportations, and that you have the power to stop the suffering, fear, and intimidation facing millions of immigrants like my family.
Your fellow American,
