Rare tetraquark is one of dozens of non-elementary particles discovered by the accelerator, and could help to test theories about strong nuclear force. The Large Hadron Collider (LHC) is also a big hadron discoverer. The atom smasher near Geneva, Switzerland, is most famous for demonstrating the existence of the Higgs boson in 2012, a discovery that slotted into place the final keystone of the current classification of elementary particles. But the LHC has also netted dozens of the non-elementary particles called hadrons — those that, like protons and neutrons, are made of quarks.

Scientists in China have developed the hardest and strongest glassy material known so far that can scratch diamond crystals with ease. The researchers, including those from Yanshan University in China, noted that the new material – tentatively named AM-III – has “outstanding” mechanical and electronic properties, and could find applications in solar cells due to its “ultra-high” strength and wear resistance.

An Australian mathematician has discovered that Babylonians may have used applied geometry roughly 1,500 years before the Greeks supposedly invented its foundations, according to a new study published in the Foundations of Science journal this month.

Around a billion years ago, a massive yellow star exploded in the constellation of Cancer. If the Kepler space telescope hadn't been looking in the right place at the right time a billion years later, we'd never know about it.

The ancient Babylonians understood key concepts in geometry, including how to make precise right-angled triangles. They used this mathematical know-how to divide up farmland – more than 1000 years before the Greek philosopher Pythagoras, with whom these ideas are associated.

A theory about black holes and how they eject light waves out of their backsides posited by Albert Einstein in 1915 has been proven correct, more than 100 years later.

Archaeologists in Morocco have announced the discovery of North Africa's oldest Stone Age hand-axe manufacturing site, dating back 1.3 million years, an international team reported Wednesday.

Scientist Elizabeth Turner found fossilized evidence of 890-million-year-old sponges. These are possibly the earliest known evidence of animal life on Earth.

Astronomers have used archival datasets from the NASA/ESA Hubble Space Telescope to reveal the first evidence for water vapour in the atmosphere of Jupiter’s moon Ganymede, the result of the thermal escape of water vapour from the moon’s icy surface.

Twenty-four hundred years ago, Heraklion was ancient Egypt’s largest port on the Mediterranean Sea. Today, the ancient city lies submerged beneath Abu Qir Bay, a few kilometers off the coast of Alexandria. Archaeologists recently discovered the wreck of a warship from the city’s final years buried in the seabed for 2,100 years beneath five meters of clay and crumbled pieces of an ancient temple to the Egyptian god Amun.

A group of scientists may have just pinpointed the location on Mars of a mysterious source of methane, a gas most often produced by microbes — and NASA's Curiosity rover could be right on top of it.

A bizarre star may have its origins in one of the most energetic events in the cosmos. Astronomers have found that a star with a very unusual composition may have formed in the wake of a new type of hypernova – a stellar explosion with 10 times the energy of a supernova.

A lubricant harvested from beetle legs reduces friction more than Teflon. The wax-like material could be used in microrobotics and small prosthetics, if a cost-effective way to synthesise it can be found.

Space Mysteries: A fast radio burst was detected from within our galaxy for the first time. We may be closer to uncovering its origin.

Astronomers have discovered the smallest yet most massive white dwarf star ever seen. According to a new study published Thursday in the journal Nature, the "very special" star has a mass greater than that of our sun, all packed into a relatively small body, similar in size to our moon. It formed when two less massive white dwarf stars, which spent their lives as a pair orbiting around each other, collided and merged together.

A new scientific report claims that there is a secret sunken continent under Iceland. This news comes by way of StudyFinds, which reports that the belief that Iceland sits atop a sunken continent has long been held by some in the science community.

Scientists in Australia have classified a new species of dinosaur, discovered in 2007, as the largest ever found on the continent. The Australotitan cooperensis or "the southern titan", is among the 15 largest dinosaurs found worldwide. Experts said the titanosaur would have been up to 6.5m (21ft) tall and 30m long, or "as long as a basketball court".

A scientifically mysterious, isolated cloud bigger than the Milky Way has been found by a research team at The University of Alabama in Huntsville (UAH) in a "no-man's land" for galaxies. The so-called orphan or lonely cloud is full of hot gas with temperatures of 10,000-10,000,000 degrees Kelvin (K) and a total mass 10 billion times the mass of the sun. That makes it larger than the mass of small galaxies.

In their death throes, roughly 97% of all stars become a smoldering stellar zombie called a white dwarf, one of the densest objects in the cosmos. A newly discovered white dwarf is being hailed as the most "extreme" one of these on record, cramming a frightful amount of mass into a surprisingly small package.

Forests of Judean date palm trees once covered ancient Israel, from Lake Galilee to the Dead Sea. The fruit of the tree symbolised life and prosperity and was praised in ancient literature for its unique medicinal properties. But the dates of Judea were made extinct by the Middle Ages. Now a team of scientists has succeeded in resurrecting the ancient tree.
