The oldest equatorial dinosaur in the world, and North America’s oldest dinosaur, has been described in a new study. Dating back 230 million years, the chicken-sized dinosaur has big implications for our understanding of how dinosaurs spread across the world, pushing back their arrival in the northern hemisphere by millions of years.

Ants remember their encounters with individuals from another nest and treat every member of that nest accordingly. Although this demonstrates remarkable capacity given their tiny brains, it may also explain why ants are one of the few species besides humans that fight extended wars. Advertisement Ants recognize members of their own nests through scent, and […]

In 2022, the US Supreme Court’s decision in the case Dobbs v Jackson Women’s Health Organization effectively ended constitutional protections for abortion by overturning the landmark decision Roe v Wade. New research shows that by August of that year – just two months later – significantly more young US adults had sought permanent contraceptive procedures. […]

Your stomach contains hydrochloric acid, a highly corrosive chemical compound that can dissolve certain metals and would spell seriously bad news anywhere else in (or on) the body. Its purpose is to create the ideal environment for digestive enzymes to break down food and kill off bacteria, and yet despite its ferocity as an acid, […]

Washington DC may be the heart of US politics today, but it wasn’t always destined to be the nation’s capital. In fact, there were moments in history when other cities held that prestigious title. So, how did we arrive at today’s capital, and why wasn’t it always a certainty? Advertisement During the Revolutionary War – […]

Living things have been known to glow thanks to a nifty trick called bioluminescence, but it’s something we more typically associate with animals of the deep sea than those stomping around surface-side. It may surprise you, then, to learn that bioluminescence has been detected in humans. That’s right, we glow in the dark – it’s […]

NASA has announced the next steps for its beleaguered Mars Sample Return mission, the ambitious plans to retrieve multiple samples collected on the Red Planet, so they can be analyzed by more sophisticated labs on Earth. The mission was deemed too expensive, with a price tag of $11 billion dollars, and it would take too […]

Whale sharks, despite being the largest fish in the ocean, still have pretty secretive sex lives. What we do know about the reproductive behaviors of whale sharks is largely based on observations from aquariums or chance encounters in the wild – however, off the coast of Western Australia, scientists have witnessed what they believe to […]

A long-term study of the mating behavior of Seychelles warblers (Acrocephalus sechellensis) has provided some insight into the factors that influence whether bird couples stay together or part ways. The findings don’t always match those from other species, opening up opportunities to explore the reasons for the differences. Raising young is hard, and many birds […]

Ancient texts speak of a strange and valuable metal known as orichalcum. The mystical material was often dismissed as a fantastical invention – until they discovered a large cache of the stuff in the Mediterranean Sea. Advertisement Orichalcum’s name is derived from the Greek for “mountain copper.” One of its most prominent mentions comes in […]

In 2010, a 71-year-old man turned up to an emergency department in Verona, Italy, experiencing shortness of breath. A fairly standard case to see in an ED, it could be assumed. However, this patient was more unique than meets the eye – he had two hearts. While the man was only born with one – […]

A mere 90 million years ago, Antarctica was a radically different place. Instead of being a polar desert characterized by colossal ice sheets and glaciers, it may have been a swampy land of rainforests dominated by ferns and conifer trees. Advertisement Scientists from the Alfred Wegener Institute in Germany and Imperial College London came across […]

Albert Einstein, recipient of the Nobel Prize in physics for his work on the photoelectric effect and the great physicist behind general and special relativity, once said: “The exaggerated esteem in which my lifework is held makes me very ill at ease. I feel compelled to think of myself as an involuntary swindler.” Advertisement Given […]

The brain has its own washing machine to clear out waste products known as the glymphatic system. We’ve known about it for a while, but nobody was exactly sure what was driving the system – until now. New research studying mice has uncovered how a molecule called norepinephrine plays a key role in “brainwashing” mice […]

Recently, a 45-year-old woman was surprised to find out she had tonsilitis and needed to have her tonsils removed. While this is a normal procedure, what was so surprising was that she had already had her tonsils removed 40 years ago, aged 5.  Advertisement “I knew that there was some sort of little flap or […]

A large asteroid is about to make its closest approach to Earth in 100 years. Over the coming days, it’s so close you should be able to observe it yourself with only the aid of binoculars.  Advertisement Asteroid (887) Alinda was first discovered by German astronomer Max Wolf at Heidelberg Observatory on January 3, 1918. […]

Geoscientists have used earthquakes to study the composition of the lower portion of the Earth’s mantle under the Pacific Ocean – and they’ve discovered something quite peculiar. There are zones where the seismic waves move in different ways, suggesting structures that are colder or have a different composition than the surrounding molten rocks. The team […]

Offshore wind farms are a valuable source of renewable energy and a crucial weapon in our arsenal in the fight against the climate crisis, but is this at the expense of marine mammals? President-elect Donald Trump suggested so in a recent press conference – though, not for the first time, his statements lacked credible backing […]

An enormous Bronze-Age “mega fortress” has been revealed in the Caucasus mountains, leaving researchers puzzled as to the function that this colossal prehistoric structure played on the crossroads between Europe and Asia. Known as Dmanisis Gora, the huge fortified settlement dwarfs all other nearby fortresses, yet contains precious few clues as to who occupied it. […]

NASA is sending an exciting mission to the Moon on board a commercial lander, Firefly Aerospace’s Blue Ghost Mission 1. The lander is carrying ten scientific instruments, most of them to study the Moon, but one is going to look back at our planet: the Lunar Environment Heliospheric X-ray Imager (LEXI). Advertisement LEXI will take […]
