An Amazon tribe has made first contact with the outside world — but may now be in grave danger

Thought there were no undiscovered tribes left? Think again: Last month, an indigenous Amazonian tribe made contact with civilization for the first time — to save itself. 

For weeks, the unidentified tribe — which was previously photographed in 2008 — has been spotted traveling on the border between Brazil and Peru. But the Brazilian government announced last week that the tribe has indeed made peaceful contact with Ashaninka Indians in Brazil’s Acre state along the Envira River in order, it appears, to escape illegal logging and drug trafficking in the area.

"Something serious must have happened," José Carlos Meirelles, who monitored the region for 20 years with the Brazilian Indian Affairs Department (FUNAI), said in a statement. "It is not normal for such a large group of uncontacted Indians to approach in this way. This is a completely new and worrying situation, and we currently do not know what has caused it."

Birth control, now in 16-year microchip form 

Thanks to the Bill and Melinda Gates Foundation, a woman who doesn’t want to get pregnant could soon implant a matchstick-sized, wireless chip under her arm, stomach or butt and be “on the pill” for years — 16 years, to be exact.
At the moment, no hormonal birth control exists that lasts for more than five years. Non-hormonal copper IUDs last 12.

Burst spinal artery aneurysm linked to Ecstasy use
Taking the street drug Ecstasy could lead to a potentially fatal weakening and rupture of the spinal cord artery, doctors have warned in the Journal of NeuroInterventional Surgery.
Posterior spinal artery aneurysms - a blood-filled swelling of the spinal cord artery, caused by a weakening and distension of the vessel wall - are rare, with only 12 cases reported to date. But all of them caused spinal bleeding which affected the function of the spinal cord.
Doctors discovered one of these aneurysms in a previously healthy teenager who had taken Ecstasy or MDMA.
The morning after the night before, he woke up with headache, neck pain and muscle spasms. After a week these symptoms suddenly took a turn for the worse, accompanied by nausea, prompting him to seek help at his local emergency department.
A week later the teen was transferred to a specialist neurosurgical unit for further investigations, which revealed an aneurysm, measuring 2 x 1 mm, on the left side of the spinal cord artery at the back of his neck.
The aneurysm was successfully removed, along with the weakened portion of the artery. The teen made a full recovery, with no lasting nerve damage.
But the authors reiterate that Ecstasy use has already been linked to severe systemic and neurological complications, including stroke, inflammation of the arteries in the brain (vasculitis) and internal brain bleeds.
And now, posterior spinal artery aneurysm can be added to the list, they say.
The drug acts on the sympathetic nervous system, sparking a sudden hike in blood pressure, as a result of the surge in serotonin it releases. And this could make any pre-existing aneurysms or other arterial abnormalities prone to rupture, they warn.
