Scientists discover largest bird ever flew

Leave a Comment
The fossilized remains of the biggest bird ever flew were discovered in 1983 in Charleston, South Carolina, but now scientists came to a conclusion: the pelagomis sandersi, who walked the planet Earth for 25 million years ago, was the largest bird ever flew.

With a magnitude of 6.4 metres, this bird's wings had twice the size of the wings of the largest flying birds today, including the albatross, with 3.5 meters long. In theory, this bird's wings were big enough to defend a football goal, from a pole to the other.

The pelagornis sandersi was extremely fast and flying at a speed of 17 meters per second. Had sharp pseudo-dentes, used to cut their prey, and could fly to distant destinations without losing altitude, according to Mashable.

"This raises the limit of what we believe the birds can be," said the author of the study, published Monday in the Proceedings of the National Academy of Sciences, Daniel Ksepka.

Ksepka, science curator and palaeontologist of the Bruce Museum in Greenwich, United States, also said that this is a very important step to realize the evolution of birds. The study of this species, however, is still at the beginning â€" among many other issues, it is still necessary to figure out how this bird could move with such grace.

5. Broccoli

Broccoli are holders of numerous beneficial properties for the metabolism. Are rich in minerals such as potassium, phosphorus, magnesium, iron and calcium, the latter with a good capacity of absorption by the body.

Copenhagen: bike utilization rate rose from 36% to 41% in just one year

Leave a Comment
In just one year â€" from 2012 to 2013 â€" the utilization rate of the bike as means of transport in Copenhagen, Denmark, increased by 5%. After years of stability in the rate of use of the vehicle, there has been an increase of 36% to 41%, in what is one of the cities with the highest rate of use of the bicycle as a means of locomotion.

But what caused this significant increase, even for a city where the bike is already widely used? Is not fully proven, but the most obvious evidence for this increase of 5% is the construction of a new subway in the city, whose works are held in 17 different locations and were driving within the city a Herculean task, referred to the Tree Hugger.

As such, the Danes chose to use the bike, since the 17 points of construction have abolished much of the road space for cars. It is expected that when the construction of the new subway is complete, the utilization rate of the bike back down, but at least the inhabitants of Copenhagen will have a new meter, that can be used as an alternative to the car.

The "most Portuguese village of Portugal" is built in the middle of giant boulders

Leave a Comment
Located in Beira Baixa, in the municipality of Idanha-a-Nova, near the border with Spain, Monsanto is the most Portuguese village of Portugal, where the homes merge with granitic formations.

The human presence on this site dates back to the Paleolithic period and archaeological finds indicate that Monsanto was inhabited by the Romans, Visigoths and Arabs. In 1165, the Moors were defeated by d. Afonso Henriques and the place of Monsanto was donated to the Knights Templar. In 1174, received the first Charter.

Monsanto could be like any other Portuguese village, hadn't been built under large granite formations. In the early days of the village, the inhabitants did not know or had means to cut rock and as such were the houses and streets that have adapted to the site and not the other way around. Many of the houses still retain Monsanto porticos in Manueline style, dating from the late 16th century, referred to in Inhabitat.

Monsanto is a living example of how people have adapted to preserve the integrity of the site for centuries.

England: families forced to live alongside garbage mountain

Leave a Comment
The residents of Cornwall Drive in St Paul's Cray, Brombley, near London, are forced to live next to a mountain of garbage for three years. The pile of trash is located down the street and reaches more than 12 feet tall and more than 18 meters wide â€" piling up a total of 18,000 tons of garbage.

During the summer, residents are prevented from enjoying their gardens or open the Windows to ventilate the House due to the unbearable smell that emanates from the mountain of garbage. The houses on the street have already lost business value, and the residents fear for their health and for their children.

Residents accuse the company that manages the location of fails to deliver payments to that trash can be sent for treatment or for recycling. "It's a nightmare. The dust, the trucks and their noises. The smell is sometimes nauseating, like burning plastic. Sometimes enters into the House. I've been sick several times because of it, "says Alan Cowburn, a resident of the street.

Currently, the case is in court, but still nothing has been decided about the future of the mountain of garbage.
