Astronomers have detected a really bizarre radio signal from space that repeats every hour, cycling through three different states. While they have some ideas about its origin it can’t be explained by our current understanding of physics.

Obstructive sleep apnea can cause or contribute to high blood pressure, so a new study examined which sleep apnea treatments – a CPAP machine or a mouthguard that keeps the airways open – was more effective at lowering blood pressure.

Geologists have shed new light on Earth's built-in thermostat. They say shifting tectonic plates that slowed volcanic activity is likely what caused the extreme ice age that turned the planet into a giant snowball over 700 million years ago.

An oral insulin that has proven effective at reducing blood glucose and avoiding hypoglycemia in mice, rats, and baboons is set for human clinical trials as soon as 2025. The researchers are hopeful the drug be available to all in a few years.

Table tennis is one of those sports that most people would likely assume is simply unplayable by the blind. An Australian student, however, is now using cameras and speakers to get unsighted individuals in on the ping pong action.

Scientists in Australia have used quantum computers to observe something usually too fast for the eye to see. The team managed to slow down a molecular interaction by 100 billion times to see what’s really going on in a common chemical reaction.

In a twist on using animals as biological control, a method that in the past has often had disastrous outcomes for native wildlife, scientists have successfully trained native bush rats to actively seek out a new food source they’ve never seen before.

A new study has found that short bursts of vigorous physical activity lasting just a few minutes incorporated into daily activities reduce cancer risk. It’s great news for people who don’t have time to – or don’t want to – go to the gym to work out.

Scientists using quasars as cosmic clocks have observed that when the universe was just a billion years old, time ran five times slower, helping to confirm Einstein's general theory of relativity and the expansion of the universe.

Researchers have created a device that uses photonic radar to remotely and accurately monitor breathing, even distinguishing between more than one patient. The device might one day be used in hospitals, aged care facilities, prisons, and at home.

Despite their risks, opioids are commonly prescribed as a first-line treatment for acute lower back and neck pain. Researchers have found that, compared to opioids, a placebo is more effective in reducing acute – short-term – back and neck pain.

Astronomers have discovered a planet that seems to have somehow survived an apocalyptic scenario. The hot Jupiter closely orbits a giant star that by all logic should have engulfed it, but the team has a few hypotheses about how it’s still standing.
