The Sun is a mere 10-watt bulb compared to quasars, extremely luminous galactic cores that shine so intensely thanks to their ravenous hunger for nearby material. Now, astronomers have detected the brightest quasar ever found, shining with the light of almost 600 trillion Suns.

​Training a dog to help the disabled or to sniff out bombs is a complex process, so if you're going to do it, you want to end up with a "usable" animal at the end. A new cognitive-ability test could help determine which canines are going to make the cut, so time isn't wasted on those that won't.

It’s long been believed that cytomegalovirus (CMV) probably weakens the immune system in older people, but now mice tests have shown that the opposite is true – somehow, the virus gives the immune system a bit of a late-stage boost.

Thanks to a global network of 18 robotic telescopes, researchers caught a brief blue glow in the sky which, they say, was the result of a different kind of supernova explosion. The find reveals surprising information about the companion star next to the white dwarf that sparked the spectacle.

There's no such thing as laundry day in space because there's no economical way to wash clothes there. To make things a bit less manky, a University of Arizona undergraduate is developing a new system to clean astronauts' clothes and make them last longer while conserving water.

A team of University of Arizona researchers led by Kate Su have used NASA's Stratospheric Observatory for Infrared Astronomy (SOFIA) flying observatory to take a closer look at a system 10.5 light years away and discovered it has a familiar general structure.

Rats can breed like crazy, so New York City and SenesTech are working to put a stop to that, with a birth control substance called ContraPest that renders both males and females infertile. The method is said to be humane, environmentally friendly and pose no risk to humans, pets and other animals.

Chronic lack of sleep has been linked to everything from high blood pressure to aging skin. Now researchers have done a study that seems to suggest missing shuteye has another less serious side effect: the inability to tell when someone else is happy or sad by looking at his or her face.

Aflatoxins in fungi have been linked to stunted growth in children, liver cancer, and immune suppression. Now, researchers have genetically modified corn plants to fight back, by letting them send “Trojan horse” molecules into the fungus to neutralize its ability to produce the toxins.

Although opioids may help relieve chronic pain, they can cause serious side effects. So, what alternatives are there? Well, new research from the University of Arizona indicates that exposure to green light may be another way to go.

Scientists at the University of Arizona recently conducted a study in which a group of 18 autistic children received fecal transplants from donors with healthy gastrointestinal systems. Not only did the procedure help to "rebalance" their gut flora, but it also improved their behaviour.​

Scientists have identified a compound found in natural food additive annatto that prevents the formation of cancer cells resulting from UV radiation in mice, with the researchers now exploring whether annatto-rich diets can prevent similar sun damage in humans. ​​
