Gravitational waves are perfectly suited to be turned to sound. The little chirp, the moment the collisions happen, it has already turned into little sounds. My ringtone, on the rare occasions my phone has sound, is one of those chirps. Now, the team at Audio Universe has taken the gravitational wave data to a whole […]

For the first time, researchers have discovered a potential explanation for Gulf War Illness (GWI), a condition that has afflicted many veterans of the 1991 Gulf War. The condition is likely caused by intense exposure to hazardous chemicals and biological agents at the time. Advertisement GWI, or sometimes Gulf War Syndrome (GWS), is a chronic, […]

Pulsars are some of the best clocks in the universe, surpassed only by the most advanced timekeeping pieces we have invented. They are the product of a supernova explosion, living behind a neutron star rotating rapidly and releasing pulses of light. Those are the beats of these cosmic clocks. And they might be used to […]

Everybody loves a teeny tiny animal. I mean, c’mon, have you seen the pea-sized frog? Or the recently discovered mini deer species? Perhaps you’ve been tempted to slip a fluffy, tent-building Honduran white bat in your pocket. Well, it’s time to introduce you to another itsy-bitsy animal to squeal over: the bee hummingbird (Mellisuga helenae), […]

Venus has got a little more rhythm across its clouds thanks to NASA and Missy Elliott. The space agency and the artist collaborated to send an inspirational message and the lyrics to one of her songs to the planet Venus. Advertisement The song chosen was The Rain (Supa Dupa Fly). It has become the first […]

Biological microorganisms are energy efficient, proliferate easily, and move autonomously. This makes them ideal sources of power for biohybrid machines. Scientists have now designed the first micromotors powered by algae. If you thought animals driving cars was impressive, get a load of this.  The alga in question is called Chlamydomonas reinhardtii, a single-celled green alga. […]

Exploring another planet is difficult, but NASA’s Institute for Advanced Concepts (NIAC) has one solution that might make it a little easier: a swarm of robot bees. Advertisement NASA has already flown a robot on Mars, the Ingenuity helicopter, which sent its final message back to Earth earlier this year. The robot performed better than […]

We have all been there – when you are trying to communicate with another person but you don’t share a common language. This can be because you are on holiday, on a video call with colleagues halfway across the world, a student in a new country, or even have in-laws who speak a different language […]

On Thursday, July 11, the second stage engine of a SpaceX Falcon 9 rocket failed to ignite and likely exploded about one hour after launch. It took off from Vandenberg Space Force Base in Santa Barbara County, California, carrying 20 Starlink satellites. This was supposed to be a routine launch but it led to the […]

The rise and fall of the last El Niño phase has been beautifully captured in newly released data visualizations. Ocean conditions may look peaceful in the Pacific at the moment, but big change is brewing. Advertisement El Niño is a global climate phenomenon that has impacts on weather patterns worldwide, but it all starts with […]

Redating of five fossils from southeastern Spain places these as comfortably the oldest evidence of hominids in Europe. If correct, this provides strong evidence for the claim that members of the Homo genus first reached Europe by crossing the open water between Morocco and Gibraltar, implying a level of technological sophistication previously thought to have […]

A team of astronomers has proposed a new definition of a planet ahead of the International Astronomical Union’s (IAU’s) General Assembly next month. Don’t hold your breath, Pluto fans. Advertisement As we learn more about the Solar System and beyond, our understanding of what constitutes a planet has changed. The classic example came in 2006 […]

Whale species in Earth’s oceans are some of the most majestic and captivating animals the world has to offer. From the biggest blue whale to sperm whales and everything in between, few people get the chance to appreciate these marine mammals. However, almost 60,000 beluga whales are now on the move as part of their […]

How do anesthetics stop us from perceiving the world around us? Some may knock us out by making the brain temporarily more unstable, a new study focusing on the drug propofol suggests. Advertisement Anesthesia: the word itself comes from the ancient Greek “an” (without) and “aesthesis” (sensation). Anesthesia is medically described as a combination of […]

With 200 billion trillion (ish) stars in the universe and 13.7 billion years that have elapsed since it all began, you might be wondering where all the alien civilizations are. This is the basic question behind the Fermi paradox, the tension between our suspicions of the potential for life in the universe (given planets found […]

In a quiet pocket of Mexico, archaeologists have used LiDAR imaging to reveal long-lost structures built by the Maya culture centuries ago. Among the discoveries are grand pyramids and a civic-ceremonial center, plus a subterranean structure found beneath a Maya ball court. Advertisement The recent archaeological work was carried out by Mexico’s National Institute of […]

New research shows that the Cambrian explosion, one of the most important interludes in the story of life on Earth, may have been triggered by a small increase in oxygen levels. Using datasets from an international consortium of scientists, the team show that modest changes in oxygen levels may have been enough to cause the […]

Your face is the result of thousands of years of lovemaking between multiple human species, with Neanderthals, Denisovans, and Homo sapiens being the main players in this ancient three-way romance. Because of a lack of physical evidence, however, we don’t really know how the features we’ve inherited compare to those of our extinct lovers – […]

Astronomers have spotted a neutron star whose jet is changing direction for the first time. Likened to a garden sprinkler, the jet is coming from the phenomenal object Circinus X-1, one of the brightest and best-studied objects in the X-ray sky. However, it turns out that there is a lot more to discover about this […]

A tunnel has been identified under the surface of the Moon for the first time, appropriately on the Sea of Tranquility where humans first set foot. Although this particular spot is not a likely place to build a future colony, where there is one cave there are likely to be more, boosting the prospects for […]
