Does Pluto have an ocean hiding beneath its surface?

If there's one place in our solar system you would expect to be as frozen solid as a box of forgotten ice lollies, it would be Pluto. However, PhD student Noah Hammond at Brown University says that data returned in 2015 by NASA's unmanned New Horizons deep-space probe indicates that the dwarf planet may have a subsurface ocean similar to those suspected to exist on some moons of Jupiter and may be responsible for the unusual surface features.Read More

Taking control of key protein helps mice fend off cancer

The spread of cancer is a complex process, and for tumors to grow, the cells of the disease must first find tissue that'll let it thrive. We know that the disease prepares the tissue by acting upon a protein that suppresses the body's natural defences, clearing the way for tumor growth. Now, scientists have worked to take back control of the protein, restoring defences against cancer in laboratory mice.Read More

Material with new record melting point predicted

New research predicts it is possible to create a material with a new record-setting melting point that would have a good chance of staying intact, even at the insane temperatures in places like the outer edges of Earth's core. Computer simulations run by a team from Brown University find that a precise combination of hafnium, nitrogen and carbon would have a melting point of 4,400 kelvin (7,460° F/4,127° C).Read More

World's oldest computer may be older than previously thought

Since its discovery over a century ago, the Antikythera Mechanism has had scholars scratching their heads over how the Greeks managed to build a mechanical computer a hundred years before the birth of Christ and thousands of years before anything similar. But now things have become even stranger as researchers claim that it's over a hundred years older than previously believed and may have been built by a famous hand.Read More

Borospherene bounces into buckyball family

Buckyballs (or Buckminsterfullerene), the soccer ball-like structures of 60 carbon atoms, have a new playmate. Previously only theorized, researchers from Brown University in the US and Shanxi and Tsinghua Universities in China have been the first to experimentally observe a boron "buckyball."Read More

Device for detecting glucose levels in saliva comes a step closer

Two years ago, we first heard about how scientists at Rhode Island's Brown University were developing a biochip for detecting very low concentrations of glucose in saliva. Such a device could make life much easier for diabetics, as it would save them from having to perform fingerprick blood tests. At the time, it was limited to detecting glucose in water. Now, however, it's able to do so within a mixture of water, salts and select enzymes – also known as artificial saliva. Read More
