In recent years, a growing number of scientific studies have backed an alarming hypothesis: Alzheimer's disease isn't just a disease, it's an infection.

This time last year, the first primates cloned through a nucleus transfer technique made headlines around the world. Now, Chinese researchers have pushed the envelope even further – by breaking a regulatory gene in macaques before cloning them.

Earth's oldest known rock may have been found, in the last place anyone would have thought to look for it: in samples of rock from the Moon, brought back home to Earth by Apollo 14 astronauts in 1971.

A few years ago, the Hubble Space Telescope did something amazing: over the course of 841 orbits and hundreds of exposures, it imaged a tiny region of space in the constellation of Fornax, peeling back the layers of time by 13 billion years, to jus

No matter how abundant or renewable, solar power has a thorn in its side. There is still no cheap and efficient long-term storage for the energy that it generates.

Arthur Ashkin, the world's oldest Nobel Prize winner, favours comfort over style. When I met him in his New Jersey home, he was sporting a fleece-lined zip-up, corduroy pants, and fuzz-lined Crocs.

Climate change is pulling back the curtain and exposing an Arctic landscape not seen by the Sun in 40,000 years or more.

Normally, after running a five-year experiment, scientists might pat each other on the back in earnest recognition of having finally made it to the end of an epic, demanding research effort.

Antibiotic resistance, one of the biggest health threats of our time, has been spreading its wings across the face of our planet. And now, researchers have detected signs of it in one of the most remote inhabited areas on Earth.

Antarctica is not in a good place. In the space of only decades, the continent has lost trillions of tonnes of ice at alarming rates we can't keep up with, even in places we once thought were safe.

Curiosity has been puttering away out there on Mars since August 2012, but she still has a few surprises tucked inside her weathered chassis.

Two decades after the hypothetical prediction that it should be possible, scientists have been able to produce fractal light from a laser.

Since it was first detected hurling through our Solar System, the interstellar object known as 'Oumuamua has been a source of immense scientific interest.

By the end of the century, if not sooner, the world's oceans will be bluer and greener thanks to a warming climate, scientists reported Monday.

Scientists have just found a new distinction between the brains of the two sexes: age-related changes to the brain occur more slowly in women than in men.

When an earthquake struck near the Indonesian island of Sulawesi on September 28 last year, thousands of people lost their lives. Dragged out to sea, buried in mud, they were the victims of 2018's most devastating earthquake.

For Elon Musk and SpaceX, the company he founded to reignite space exploration, a great deal hinges on the creation of the Starship.

The humble honeybee can use symbols to perform basic maths including addition and subtraction, shows new research published today in the journal Science Advances.
