There are constant reminders in our everyday environment of the many episodes of life that unfolded on Earth.

Rocks and dirt preserve evidence of ages before us The oldest fossil forest on the planet 390 million years ago unusual trees grew.

Fossils reveal the diversity of life that flourished and disappeared over thousands of years, and graves tell stories People who lived through unimaginable hardships Centuries ago.

The constant of life on Earth is that it is constantly changing. Even scientists can't agree A new chapter in Earth's history or not It has started.

While it may seem impossible to bring long-extinct species back to life, scientists are making breakthroughs that may bring them back, perhaps in the not-so-distant future.

An ambitious project to genetically engineer a woolly mammoth that hasn't roamed the earth in 4,000 years has taken another step towards reality.

Colossal Biosciences, a Dallas-based company aiming to create a mammoth hybrid that looks exactly like its extinct counterpart, has reprogrammed cells from an Asian elephant. The closest animal species to the woolly mammoth.

Now the modified cells can eventually be used A hybrid mammoth can help grow a woolly coat And develop other traits necessary for survival in the Arctic.

The company hopes that resurrecting the woolly mammoth will help restore the vulnerable Arctic tundra, which is threatened by global warming.

The James Webb Space Telescope's telescopic infrared vision has spied a mysterious galaxy that existed when the universe was 700 million years old — in its youth, astronomically speaking.

This discovery surprised the scientists and they discovered it The oldest “dead” galaxy ever observedAnd it stopped forming stars almost as soon as star birth began in the universe.

Violent interactions between stars or black holes can rob galaxies of the gas they need to form stars, but so far, no theories have fully explained what happened in this distant galaxy.

Bread and cheese are one of the best culinary pairings, but the bread in question is 8,600 years old and the cheese is known for its pungent aroma.

Archaeologists discovered palm-sized fluffy residue in an ancient hearth system in Turkey, and it An uncooked round of leavened bread made around 6600 BCIt is the oldest bread in the world.

Meanwhile, France's favourite Camembert cheese may be facing an extinction crisis.

The fungus used when making the cheese, which gives Camembert both its distinctive aroma and rich flavor, is in short supply, causing enthusiasts to worry that Camembert's days are numbered.

A stroll through Earth's forests 120 million years ago would have yielded a familiar sight amid a dinosaur-dominated landscape: birds. Well, that is, until the feathered creatures open their beaks to reveal rows of teeth.

Back then, toothed birds were in vogue. But researchers have found a fossil A new species called “Attenborough's Strange Bird”. Named after the British naturalist Sir David Attenborough, it is an oddball because it lacks teeth.

The discovery of a robin-like bird changes the way scientists think about the complex story of bird evolution.

Separately, an eagle-eyed amateur paleontologist out for a walk with his dog spotted an exposed bone, which was discovered. A nearly complete titanosaur skeleton is attached from skull to tail.

Scientists have used a unique sky pattern to determine that ancient humans were in Europe 1.4 million years ago.

Pebbles buried in a quarry in Ukraine and stone tools found beneath layers of earth were analyzed for radioactive particles locked inside mineral grains.

In the distant past, when the rocks were on the surface, cosmic rays, or charged particles that travel across the universe and land on Earth, penetrate the stone, creating radioactive markers that help researchers determine how long the archaeological layer was buried. .

The newly dated artifacts are the earliest evidence of hominins in Europe. The team is trying to determine more accurately Early humans made toolsBut research results have provided clues.
