A recently identified 512-year-old Greenland shark may be the world’s oldest living vertebrate. Although scientists discovered the 18-foot fish in the North Atlantic months ago, its age was only recently revealed in a study published in the journal Science .  Greenland sharks have the longest lifespan of any vertebrate animal, so it is perhaps unsurprising that the species would boast the oldest living individual vertebrate as well. Nonetheless, the fact that this creature may have been born as early as 1505 is remarkable. “It definitely tells us that this creature is extraordinary and it should be considered among the absolute oldest animals in the world,” said marine biologist Julius Nelson, whose research team studied the shark’s longevity. To determine the shark’s age, scientists used a mathematical model that analyzes the lens and cornea of a shark’s eye and links size of the shark to its age. Greenland sharks grow at a rate of about 1 centimeter per year, which allowed scientists to estimate a particular shark’s age. The ability to measure the age of this mysterious shark is relatively new. “Fish biologists have tried to determine the age and longevity of Greenland sharks for decades, but without success,” said Steven Campana, a shark expert from the University of Iceland. “Given that this shark is the apex predator (king of the food chain) in Arctic waters, it is almost unbelievable that we didn’t know whether the shark lives for 20 years, or for 1,000 years.” Related: Airbnb is offering a night in an underwater bedroom surrounded by 35 sharks The Greenland shark thrives in the frigid waters of the North Atlantic. Despite its considerable size, comparable to that of a great white shark, the Greenland shark is a scavenger and has never been observed hunting. Its diet primarily consists of fish, though remains of reindeer, polar bear , moose, and seals have been found in the species’ stomachs. To cope with life in deep water, the living tissues of a Greenland shark contains high levels of trimethylamine N-oxide, which makes the meat toxic. However, when the flesh is fermented, it can be consumed, as it is in Iceland as a dish known as Kæstur hákarl. Via International Business Times Images via Wikimedia and Julius Nelson

Tesla’s all-electric semi truck has a bold new competitor

Comments Off on Tesla’s all-electric semi truck has a bold new competitor

Just one month ago, Elon Musk made headlines with the debut of his revolutionary Tesla Semi Truck . The super-sized electric marvel is able to get 500 miles on a charge, reach 60 mph in five seconds without a trailer (or 20 seconds with one), and boasts regenerative braking able to recover 98 percent of kinetic energy to the battery. Impressive? Yes. But there’s another kid in town with designs to beat Musk to the market with an electric rig of his own. Dakota Semler, the 25-year-old founder and chief executive officer of Thor Trucks , has developed with his team an all-electric semi that’s been dubbed the ET-One. The ET-One is the first product from the company and Semler hopes it will be the flagship model in a robust, customizable line that will also eventually include delivery vans and work vehicles. The goal, Semler relayed to Bloomberg, is to “work on a one-off basis, customizing clients’ fleets per their specifications.” Related: Revolutionary Tesla Semi Truck arrives with a whopping 500-mile driving range Like Musk’s model, the ET-One boasts a sleek, futuristic aesthetic, an all-electric motor that ditches dirty diesel in whole, and the ability to haul up to 80,000 pounds of cargo—something currently only the industry’s highest class of trucks can tow. The Thor version also uses a 22-inch touchscreen on its dashboard which communicates with the vehicle’s electric motor and battery packs, which can carry the truck 300 miles on a charge. Thor is hoping to bring the ET-One to market in 2019 at an estimated starting price of $150,000; the Tesla Semi is expected to sell for $150,000 with a 300-mile range, and $180,000 with 500 miles of range. The prices are more than that of comparable gas semis which range from $100,000 to $125,000, but wholly competitive over the long term when factoring in the cost of fuel over the life of the truck as well as maintenance.  Electric engines require far less regular maintenance than their diesel counterparts. While Thor has a ways to go before it scales—its team is just 17 employees—it is diligently making plans to make the ET-One more widely available for demos in 2018, and hunting down the capital needed to grow (currently, the project is funded by founder Semler who also has Malibu Wine Safaris and multiple real estate companies in his portfolio). With that said, the inevitability of stricter emission rules in the coming years will surely give Thor the boost it needs. Via Bloomberg Images via Thor Trucks

Denmark just opened the "worlds most humane" maximum security prison

Comments Off on Denmark just opened the "worlds most humane" maximum security prison

The Danish island of Falster is now home to the world’s most humane maximum security penal institution, Storstrøm Prison. Designed by Danish architects C.F. Møller , the building has been hailed for its strategic features that create a vibrant community for the inmates, in lieu of the severe living conditions typically found in prisons around the world. Storstrøm, which can hold up to 250 people, is designed to be a mini-community where inmates can spend their time in an environment that is as “normal” as possible. Working with the Danish Prison Service, the architects created a vibrant community where the inmates would be reminded of a life they once left behind, therefore encouraging an eagerness to leave the system and return to society. Related: C.F. Møller is building a garden-filled vertical village in Antwerp The prison layout spans the size of 18 football fields and is centered around social activities. There are ample options for the inmates to spend their time exercising, studying, creating art , or praying in the onsite church. Additionally, inmates buy their own food at the grocery store. “We have concentrated all buildings around a center for joint activities. Here we have a square with, for example, an activity house, a grocery store, a school, a church and a devotional room. We have also made an effort to promote communication between inmates and staff,” architect Mads Mandrup of C.F. Møller told the Danish newspaper Berlingske. The cell conditions are also designed to provide a bearable lifestyle while incarcerated. The cells are 13 square meters and come equipped with a refrigerator, closet, and a 22-inch television. The cell’s floor-to-ceiling windows flood the interior with natural light , but are angled in a way to protect privacy. Although being hailed as a strategic design to help prisoners adjust to prison life, the various amenities have caused some to criticize the design as being too lofty for lawbreakers. However, officials claim that despite the decent living conditions on the inside, the prison is still a high-security fortress with a six-meter high wall and tension steel wires around the perimeter of the complex. + C.F.
