​Is it ok for vegetarians to eat fish? Turns out this dietary dilemma may date back further than we thought – to around 75 million years ago, in fact. Paleontologists studying the droppings of what was thought to be a strictly herbivorous dinosaur have found evidence they enjoyed the odd cheat day.

A miniature, pliable, wearable acoustic sensor that captures physiological waves generated in the human body, has been developed. The device allows human health monitoring and the wearer to control remote devices with spoken words.

Beer-brewing wastewater can't just be dumped in the sewer – it has to be filtered first, which can be expensive. Now, however, there may be a new use for the water. It could be used to grow a fungus that's in turn made into "green" battery electrodes. ​

If Arctic sea ice melting trends continue, a US military base, built into the Greenland Ice Sheet and abandoned since the 1960s, could eventually be freed from the ice – along with hundreds of thousands of liters of waste and pollutants.

Researchers have found that leukemia stem cells can thrive in a patient's fatty tissue, which they can transform into a supportive hideout that makes the cancer cells more resistant to chemotherapy treatments.

Proponents of e-bikes point out that they may open bicycle-commuting up to people who would otherwise never bother with it, thus providing them with more exercise. A new study confirms that in such cases, use of an e-bike does indeed boost the user's fitness level.

A new tool could have a big impact on which treatment doctors decide to use to tackle cancer, using data from whole exome sequencing to pick out drugs likely to prove effective at tackling tumors on a case-by-case basis.

New research being conducted at the University of Colorado Boulder has found that tiny particles known as quantum dots might be useful in tackling antibiotic-resistant bacteria, which cause in excess of 23,000 deaths in the US every year.

Optogenetics, where brains cells are made to behave differently when exposed to light, has wide-ranging potential. With one eye on this area of neuroscience, scientists have developed a device the width of a human hair that can be planted in the brain to deliver light or drugs only where needed.

NASA's Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft has detected an aurora occurring deep in the Martian atmosphere, and an as of yet unexplained high altitude dust cloud.

A treatment process developed by engineers at the University of Colorado Boulder promises a simpler and more economical way to clean up the wastewater produced by oil and gas operations that is heavily salinated and full of organic contaminants.

One possibility for replacing the Hubble space telescope is the Aragoscope from the University of Colorado Boulder, which uses a gigantic orbital disk instead of a mirror to produce images 1,000 times sharper than the Hubble's best efforts.
