The Dinosaur Family Tree Gets A Makeover

About 130-years ago Harry Govier Seeley, a paleontologist trained in Cambridge, classified dinosaurs into two distinct groups, or clades, based on the shape of their pelvic bones. The “reptile-hipped” saurischians included carnivorous theropods like the Tyrannosaurus Rex (T-Rex), while the “bird-hipped” ornithischians comprised herbivores such as the Stegosaurus and Triceratops. As more dinosaur fossils were discovered, a third group, dubbed sauropodomorphs, was established. In 1887, Seeley concluded that the long-necked herbivorous sauropods, like Brontosaurus, were related to theropods and placed them under the saurischians.

Graphene Sieve May Help Solve The World's Water Woes

Though 70% of the Earth is covered in water, only about 2.5% is fresh. Even worse, only 1% of the fresh water is readily accessible, the rest being trapped in glaciers or deep underground. It is therefore not surprising to hear that over 780 million people worldwide currently do not have easy access to clean water. The problems are only expected to get worse with climate change and the burgeoning world population. Though desalinating sea water is the most logical solution, current techniques are too expensive and cumbersome to deploy on a large scale.

Flying Cars Edge Closer To Reality

Flying cars have been in the works since 1946, when aeronautical engineer Ted Hall created two prototypes of the ConvAirCar. Unfortunately, a crash landing due to low fuel caused the hybrid vehicle’s manufacturer, Convair, to lose interest and shut down the venture within a year. While there have been numerous attempts since, none have gone beyond the experimental stage. That is about to change thanks to a slew of new and established companies that are determined to make this 70-year-old quest a reality.

Video Of The Week — Doggy Ice Cream Parlor Is A Success With Canines

All canine owners know that feeding their pets regular ice cream can result in serious health issues. Many dogs are lactose intolerant and consumption of dairy upsets their digestive systems. Moreover, just like in humans, eating large amounts of sugar causes dogs to become hyper and unfocused, and can also result in dental cavities, diabetes, and obesity. Now, thanks to Mauricio Montoya, some lucky dogs in Mexico City are finally able to enjoy the frozen treat without their owners worrying about any harmful side effects.

Wizard Hat Amoeba Named After Gandalf From The Lord Of the Rings

Single-celled amoebae, which resemble small blobs of jelly, are usually of interest only to the researchers that discover them. However, a new South American species is garnering significant attention from fans of the epic Lord of the Rings trilogy by J.R.R.Tolkien. That’s because its unique shell, or carapace, bears a close similarity to the hat donned by Gandalf, the powerful wizard leader of the Fellowship of the Ring and the army of the West.

The grassroots movement, which is now celebrated by over 2 billion people in 192 countries, led to the enactment of numerous environmental laws, including the Clean Air Act of 1970 and the Endangered Species Act of 1973.

Ooho Edible Water Bubble Aims To Eliminate Plastic Bottles

It is a well-known fact that plastic bottles, which take hundreds of years to decompose, are harmful to our environment. However, efforts by environmentalists to encourage consumers to switch to alternatives, like water fountains or reusable bottles, have not been very effective. The U.S. alone utilizes over 50 million plastic bottles annually, 80% of which end up in landfills.
