DON'T LET THE DISEASE-CARRYING FLEAS BITE!

Rat Art
What could possibly be worse than the skittering impression left by a New York City rat after it runs across your foot? The knowledge that the rodent could be carrying disease-ridden fleas.
study published today in the Journal of Medical Entomology examined the hitchhikers on 133 New York City rats, captured at five locations throughout Manhattan over the course of 10 months. The researchers catalogued everything, from fleas down to bacteria--and what they found wasn't great. While numerous critters clung to the rats' carcasses, including lice and mites, what really caught the attention of the researchers was the presence of the Oriental rat flea (Xenopsylla cheopis).
That particular flea is a notorious carrier of diseases like bubonic plague andmurine typhus. "If these rats carry fleas that could transmit the plague to people, then the pathogen itself is the only piece missing from the transmission cycle," Michael Frye, lead author of the paper says in a press release.
It sounds bad, but don't panic... yet. A. You know where your towel is, and B: No plague bacteria were actually found in the fleas, though a few species of the disease-causing bacteria Bartonella were found. Also, 94.1 percent of the fleas were found at a single collection station. Keeping an eye on species hotspots like that one could go a long way towards identifying and preventing future epidemics.
That being said, keeping the population of rats and fleas down in the city would also be good practice. Humans aren't fleas' first choice, though they will happily chow down on us if their rat hosts are unavailable, and disease is more likely to spread when humans are in close contact with rodent populations. Reduce the amount of contact between the two, and there are fewer chances for fleas to jump between species.

UK Lord Justice wanted age of consent lowered to the age of 4

Lord Justice Fulford was named last year as an adviser to the QueenHe was a key backer of the notorious Paedophile Information Exchange Police suspect the group of abusing children on an ‘industrial scale’He is revealed as a founder member of campaign to defend PIEAt the time it was calling for the age of consent to be lowered to just fourI clashed with Paedophile Information Exchange (PIE) global leaders at the Wales conference in Swansea in 1977. Tom O’Carroll is still accepted and active on a sexnet chat group of experts in “sexology” although he writes openly as a pedophile. And the scholarly organizers of the Swansea conference at the University were part of his efforts. Below a summary of my intro to him in my book, Stolen Honor, Stolen Innocence, 2013. This academic pedophile lobby has continued and grown, training second generation and third generation supporters as “scholars” for pedophile equality and “rights.” In 1981 I realized they were global.

Jews in Israel call for genocide of Palestinians in a massive rally ignored by the media

The West’s media—under orders to censor any news of Jewish supremacism—has refused to publicise this week’s massive hate rally attended by thousands of Jews in Tel Aviv which called for all Arabs to be killed. The Western media’s blackout is in marked contrast to their blanket coverage of the tiniest example of what it calls “white racism.” The Tel Aviv rally—organized to support an Israeli soldier who murdered a wounded Palestinian by shooting him in the head as the victim lay on his back—was marked by chants and banners calling for mass murder. The rally took place on Tuesday evening, April 19, in Tel Aviv’s Yitzhak Rabin Square, and the many thousands of Jews in the crowd were, according to reports in the Israeli media, baying for blood.
One Jewish reporter, Dan Cohen, tweeted that many in the crowd chanted, “Death to Arabs,” a frequently heard rallying cry at anti-Palestinian demonstrations. Ahmed Tibi, a Palestinian lawmaker in Israel’s parliament, posted an image of a sign displayed …

The elite's use young children's blood to live longer and so do I says Paypal Billionaire

Billionaire PayPal founder Peter Thiel said that he believes transfusions of blood from young people can reverse his ageing process and allow him to live a vastly extended lifespan.



In an interview with Inc.com’s Jeff Bercovici, Thiel said that the practice — known as parabiosis — is the closest modern science has come to creating an anti-aging panacea.

Thiel — a hedge funder who acted as a delegate for Donald Trump and spoke at the 2016 Republican National Convention — is reportedly obsessed with defying death and extending the human lifespan. He has injected funds into startups that are experimenting with ways to forestall the body’s inevitable decline and death.

“I’m looking into parabiosis stuff,” Thiel told Bercovici, “where they [injected] the young blood into older mice and they found that had a massive rejuvenating effect. … I think there are a lot of these things that have been strangely underexplored.”

Parabiosis experiments began in the 1950s with crude exercises in which rats …
