The asteroid that killed the dinosaurs was the size of Mount Everest.
About 66 million years ago, the reign of dinosaurs came to a fiery end. It flew at 27,000 mph (43,000 km/h) and hit it directly on Earth. This shock caused a cascade of fatal events that led to the fifth mass extinction that eliminated dinosaurs, with the exception of some birds. But what happened to […]
A 1,600 year old coin purse found in a complex tunnel system under Galilee records dates to continue the Jewish rebellion against the Romans
Archaeologists have excavated an unusual storage of copper coins from 1,600 years ago in Galilee, and it is possible that the coins were hidden there during the last known Jewish rebellion against the Romans. Researchers discovered 22 copper coins in a gap in a tunnel complex under the settlement known as Hukok. The tunnel was […]
We are just beginning to discover what the inner core of the Earth is truly made up of.
The iron-rich core at the heart of our planet was an important part of Earth’s evolution. The core not only moves magnetic fields that protect the atmosphere and oceans from solar radiation, but also affects plate tectonics, which have continuously reshaped the continent. However, despite its importance, many of the core’s most basic characteristics are […]

Owning a cat changes your brain. This is the way.
Cats may have an independent reputation, but new research suggests that we share our own connections with them – driven by brain chemistry. The main chemical involved is oxytocin, often called love hormone. When a mother holds a baby, a friend holds it, or develops trust and love, it is the same neurochemical. And now, […]
“Impact”: Black holes are found to grow at 2.4 times the theoretical limit
Astronomers discovered black holes of monsters in early universes. This discovery deepens the mystery of how several black holes were born shortly after the Big Bang grew so large and very quickly. We will use NASA’s Chandra X-ray observatory. It is a powerful x-ray telescope at risk of being fired by the 2026 NASA budget […]

On September 19, 1991, the hiker had passed past Ötztal Valley in the Alps as he stumbled upon a human body partially exposed in the ice.

Dentists say there are often causes of halitosis, or bad breath, that cannot be dealt with by brushing alone. So why does breathing emit a foul smell even after […]
‘Like trying to see fog in the dark’: How strange pulses of energy are helping scientists build the ultimate map of the universe
In early 2024, McGill University doctoral student Vishwangi Shah and her colleagues were conducting a routine review of data from the Canadian Hydrogen Intensity Mapping Experiment when they noticed something strange. Their analysis traced one of these pulses, known as fast radio bursts (FRBs), to the outer edge of a “dead” galaxy with no new […]
