A mathematical theorem proves that at any given moment on the surface of the earth, there exists at least one pair of points that have the exact same pressure and temperature. Borsak-Ulem Theorem defines antipodal points as specific points on a sphere that are located in exactly opposite directions from the centre of the sphere, or situated on diametrical end points along the sphere’s diameter. “If you place a piece […]

Wax Worms May Provide a Solution to Plastic Pollution

Researchers are currently investigating the potential of using worms to help combat the excessive plastic pollution around the world, thanks to a chance discovery by scientist and amateur beekeeper Federica Bertocchini. After picking parasitic wax worms off the honeycombs of her beehives, Bertocchini placed them in a plastic bag – and when she returned, she found that the worms had munched holes through the plastic and escaped. Inspired, Bertocchini began […]

Pollution-Eating Robots Could Help Protect the Planet

Researchers at the University of Bristol may have engineered a new way to clean up our planet’s waterways – with a swimming machine called “Row-bot,” which digests pollution and turns it into electricity for fuel. “Sometimes, tankers flush their oil tanks into the sea, so oil is released into the sea that way,” said roboticist Jonathan Rossiter, host of a TED Talk that discussed the potential these robots may have.

Aggressive Fungus Found Growing in Outer Space

Scientists are considering the implications of an “aggressive space fungus” identified on the outside of the Russian space station Mir. Patches of the green and black fungus have been discovered behind control panels, in the ship’s air conditioner, communications unit, and on many other surfaces. Not only was the fungus growing everywhere, the patches proved difficult to eradicate. According to Russian microbiologist Natalia Novikova, there is the potential that in […]
