Découvrez le Titanoboa, le plus gros serpent du monde

Le Titanoboa a vécu sur notre planète il y a plus de 50 millions d'années. Pouvant mesurer jusqu'à 15 mètres pour une masse de 2 tonnes, c'est la plus grande espèce de serpents jamais découverte.

De son nom complet Titanoboa Cerrejonensis, le Titanoboa est une espèce fossile de serpents qui a été découverte en 2009 dans la mine de charbon de Cerrejón en Colombie. Grâce aux restes de vertèbres retrouvés sur place, on a pu estimer les mensurations du monstre : il mesurait entre 10 et 15 mètres et pesait entre une et deux tonnes, tandis qu'il pouvait atteindre un mètre de largeur.


Non venimeux, il fait partie de la famille des serpents constricteurs. Comme les Boa ou les Pythons actuels, il tuait ses proies en les étouffant. De par sa taille gigantesque, il possédait une force phénoménale : avec ses anneaux, il était capable d'exercer une pression d'environ 280000 Kg/m². Selon la BBC, cela équivaut à ce que vous ressentiriez si vous étiez couché sous le pont de Brooklyn.

Un colosse qui se nourrissait de crocodiles


On ne sait pas précisément de quoi se nourrissait ce colosse, mais on suppose que son régime alimentaire se composait d'alligators, de crocodiles et de gros poissons. Ce serpent est apparu il y a approximativement 60 millions d'années, soit après la disparition des dinosaures. N'ayant pas de rival à sa mesure, il a été "le plus gros prédateur de la Terre pendant au moins dix millions d'années" selon le paléontologue Jonathan Bloch. A cette époque, la Terre était plus chaude qu'aujourd'hui. Ce climat était propice aux animaux à sang froid comme les serpents, qui voyaient leurs croissances favorisées. A l'inverse, les mammifères à sang chaud étaient plus petits à l'époque, à l'image des chevaux qui n'étaient pas plus grand que nos chats actuels.


Mais du coup, le réchauffement de la planète que nous vivons actuellement pourrait-il favoriser un retour de ces serpents géants ?  Techniquement oui mais rassurez-vous, ce n'est pas si simple dans les faits. Jason Head, directeur de l'équipe scientifique à l'origine de la découverte du Titanoboa, rappelle que "nous détruisons l'essentiel de leurs habitats avec le développement et la déforestation". Et même si nous arrivions à préserver ces habitats, le temps nécessaire au développement d'une nouvelle espèce est extrêmement long : "cela peut prendre un million d'années" précise son collègue Dr Carlos Jaramillo.

A Happy Marriage Leads To Better Health, Study Finds

Is marriage good for your health? In general, research suggests yes. Married people live longer, have better access to health care, enjoy a more satisfying sex life, experience less stress, live a healthier lifestyle, and have lower rates of heart disease, diabetes, and depression compared to their single counterparts.


The list of health perks conferred by marriage is so long, in fact, that the U.S. Department of Health and Human Services has made it a centerpiece of its two-year-old, $5 million national media campaign to promote wedded bliss.

But there's a catch -- men and women don't get the same or equal benefits from a legally sanctioned pairing. A man's sex life is likely to improve more than a woman's after getting married, for instance, while a woman's risk for depression tends to decrease more than her partner's when she's in a long-term relationship.


A Happy Marriage Leads To Better Health, Study Finds
And in reality, getting hitched may not be strictly necessary. Women and men can reap some health benefits just by living together, or even by being in a stable long-term relationship, research suggests. Experts believe that same-sex couples, many of whom don't even have the option to get married, also score health gains, though almost all research so far has focused only on heterosexual relationships.

"I don't think it's necessarily a matter of the marriage license; it's a matter of the level of social support and mutual attachment," says John Gallacher, Ph.D., a researcher at the Cardiff University School of Medicine in Wales, who recently published a paper on the health benefits of relationships in a BMJ journal.

We interviewed experts and sifted through the scientific research to determine which sex fares better in each of these eight categories.

In Journal, Man Wrote of Creating Silk Road, an Online Black Market, Prosecutors Say



Long before the website Silk Road became an online black market for drugs and other illicit goods, it began its life of underground commerce with the sale of homegrown hallucinogenic mushrooms, prosecutors have said.

The website’s origins were highlighted on Wednesday in Federal District Court in Manhattan, as prosecutors disclosed entries from a personal journal that they say were written by Ross W. Ulbricht, the man charged with creating Silk Road.

When Mr. Ulbricht, a 30-year-old California man, was arrested in October 2013, federal agents say they discovered the journal on his laptop computer.

In Journal, Man Wrote of Creating Silk Road, an Online Black Market, Prosecutors Say
“I began working on a project that had been in my mind for over a year,” Mr. Ulbricht wrote in one entry, prosecutors said. “I was calling it Underground Brokers, but eventually settled on Silk Road. The idea was to create a website where people could buy anything anonymously, with no trail whatsoever that could lead back to them.”

Focus Is on Bitcoin Trader at Trial Over Silk Road Black MarketJAN. 15, 2015
It was on that website, on a hidden part of the Internet, prosecutors have charged, where thousands of vendors sold drugs and other illegal goods, using Bitcoins, a digital currency as anonymous as cash.

The government has said Mr. Ulbricht ran the site under the pseudonym Dread Pirate Roberts, a charge that Mr. Ulbricht’s lawyer, Joshua L. Dratel, has denied. Mr. Ulbricht has pleaded not guilty to narcotics trafficking conspiracy and other counts.

The journal was cited by the government in late 2013 when it argued against bail for Mr. Ulbricht after he was arrested in a San Francisco library and brought to Manhattan to face charges. Last week, in an opening statement, a prosecutor said the journal had been found on Mr. Ulbricht’s laptop, to which he was logged on as Dread Pirate Roberts at the time of his arrest.

“That journal contains devastating confessions by the defendant,” the prosecutor, Timothy T. Howard, told the jury.

Thomas Kiernan, a computer scientist with the Federal Bureau of Investigation, testified on Wednesday that Mr. Ulbricht’s arrest had been carried out while he was using the laptop so agents could bypass encryption software to gain access to it.

The introduction of Mr. Ulbricht’s writings seemed to be intended to link him to Silk Road’s operations throughout its existence from 2011 to 2013.

“I imagine that someday I may have a story written about my life and it would be good to have a detailed account of it,” he wrote, according to an entry a prosecutor read aloud to the jury.

In other writings the government ascribes to Mr. Ulbricht, he said he hated working for others “and trading my time for money with no investment in myself.”

As for the website idea: “I had been studying the technology for a while, but needed a business model and strategy.”

He said he had decided to grow “shrooms” that he could sell cheaply on the site “to get people interested.”

He described his optimism about his idea. “In 2011, I am creating a year of prosperity and power beyond what I have ever experienced before,” he wrote. “Silk Road is going to become a phenomenon and at least one person will tell me about it, unknowing that I was its creator.”

At one point, Mr. Ulbricht described how he began the site: announcing it in Bitcoin discussion forums, taking his first order for mushrooms, and selling about 10 pounds in a couple of months.

As traffic grew, he wrote, “I worked all day every day, still processing transactions by hand, dealing with scammers, answering messages, meeting new strange people through my site and getting to know them.”

When the website Gawker published an article about Silk Road, Mr. Ulbricht noted, there had been “a huge spike in sign-ups.” He also cited criticism by two United States senators, which put him “into a bad state of mind,” and made him feel “extremely vulnerable and scared.”

Silk Road thrived, though, and as he made as much as $25,000 monthly, he decided to take the site “to the next level,” he wrote.

He described the hiring of employees — prosecutors have said he never met them but knew and supervised them “purely online” — one of whom had “helped me see a larger vision,” he wrote.
