Researchers examine how pink sea urchins sharpen their teeth to develop self-sharpening tools
Aside from their fearsome array of spines, sea urchins have another evolutionary edge over other sea creatures: self-sharpening teeth. According to researchers from Northwestern University, the spiny invertebrates, unlike other animals whose teeth are built to resist constant wear and tear, have teeth engineered to chip and weather in such a way that they maintain their sharp […]

Populating other worlds: Beneficial microbes can be used as primary colonists for alien planets, suggest researchers
The key to successfully terraforming the Red Planet may lie in some terrestrial microbes. According to microbiologist Jose Lopez and his colleagues W. Raquel Peixoto and Alexandre Rosado, microbes from Earth may be able to jumpstart the creation of a habitable environment on Mars, the same way early microbes kickstarted the creation of the Earth’s […]

Study suggests “space dust” from a giant asteroid caused the Ice Age 466 million years ago
A gigantic collision in the asteroid belt between Mars and Jupiter 466 million years ago plunged the Earth into a prehistoric ice age that ushered in a significant increase in marine biodiversity, scientists have revealed. This event, according to an international team of scientists and experts, occurred during the Ordovician Period, a geologic point in […]

Shapeshifting robots straight out of sci-fi can be used to explore volcanoes and caves on Titan, Saturn’s moon
Engineers at the National Aeronautics and Space Administration (NASA) have found a way to help scientists gain access to worlds located in the depths of outer space: the Shapeshifter robot. Currently being tested in a robotics yard at NASA’s Jet Propulsion Laboratory (JPL) in California, the current Shapeshifter prototype, according to its engineers, can split […]

Human hearts evolved for endurance due to shift from hunting to farming and a modern lifestyle
Hearts evolved to make humans better at endurance tasks, a new study has found. According to research conducted by scientists from Canada, the U.K. and the U.S., this change — which started around the time people shifted from being hunter-gatherers to being farmers — enabled humans to become more efficient at maintaining their energy levels over […]

Looking at the lunar surface: Harvard scientist believes the moon holds clues about extraterrestrial life
The surface of the moon may hold clues about the existence of extraterrestrial life. According to one scientist, the moon may be acting as a “fishing net” and “mailbox” for evidence of alien life. “The idea is to consider the moon’s surface as a fishing net for interstellar objects collected over time and potentially deliver building […]

Wood and web: Scientists develop wood nanofibers that could soon replace plastic
Noted for their ability to be molded and used for different purposes, plastics are some of the world’s most versatile materials. However, they are also considered to be among the most dangerous – especially for the environment. In fact, according to previous estimates by experts, there would be more plastic than fish in the world’s […]
