Researchers using advanced satellite imagery have discovered an ancient reef-like landform 'hidden' in plain view on the Nullarbor Plain, which has been preserved for millions of years since it first formed when the Plain was underwater.

Computer scientists have succeeded in developing a method for systematically finding the optimal quantum operation sequence for a quantum computer. They have developed a systematic method that applies optimal control theory (GRAPE algorithm) to identify the theoretically optimal sequence from among all conceivable quantum operation sequences. This method is expected to become a useful tool for medium-scale quantum computers and is expected to contribute to improving the performance of quantum computers and reducing environmental impact in the near future.

In 2004, construction workers in Norwich, UK, unearthed human skeletal remains that led to a historical mystery -- at least 17 bodies at the bottom of a medieval well. Using archeological records, historical documents, and ancient DNA, British researchers have now identified the individuals to be a group of Ashkenazi Jews who may have fallen victim to antisemitic violence during the 12th century. Their findings shed new light on Jewish medical history in Europe.

Scientists have developed a mathematical description of what happens within tiny magnets as they fluctuate between states when an electric current and magnetic field are applied. Their findings could act as the foundation for engineering more advanced computers that can quantify uncertainty while interpreting complex data.

A vast paleogenetic study reveals insights on migration patterns, the expansion of farming and language development from the Caucasus over western Asia and Southern Europe from the early Copper Age until the late middle ages.

Using new scientific tools, archaeologists discovered that an ancient Greek leader known today as the Griffin Warrior likely grew up around the seaside city he would one day rule. The findings are part of three new studies that examined the ancient DNA of the Griffin Warrior and 726 other people who lived before and during the Bronze Age to learn more about their origins and movements across three continents surrounding the Mediterranean Sea.

Scientists investigating the remains of an old wooden ship off the cold, windy coast of far southern Argentina say it almost certainly is the Dolphin, a globe-trotting whaling ship from Warren, R.I., lost in 1859. Archaeologists have spent years researching the ship's origin without making a definitive identification, but a new analysis of tree rings in its timbers has provided perhaps the most compelling evidence yet.

By analyzing DNA with the help of artificial intelligence (AI), an international research team has developed a method that can accurately date up to ten-thousand year-old human remains.

A modern scientific analysis of ancient stone tools is challenging long-held beliefs about what caused radical change on the island of Crete, where the first European state flourished during the Bronze Age: the 'Minoan civilization.'

Research examining traces of parasites in medieval Cambridge residents suggests that monks were almost twice as likely as ordinary townspeople to have intestinal worms -- despite monasteries of the period typically having far more sanitary facilities.

Researchers have shown that a component of modern computer processors that enables different areas of the chip to communicate with each other is susceptible to a side-channel attack. An attacker can monitor how traffic from two different cores on a processor interferes with each other to extract secret information, like a cryptographic key.

New research has provided the strongest evidence yet that Earth's continents were formed by giant meteorite impacts that were particularly prevalent during the first billion years or so of our planet's four-and-a-half-billion year history.

An archaeological study has determined that cowrie-shell artifacts found throughout the Mariana Islands were lures used for hunting octopuses and that the devices, similar versions of which have been found on islands across the Pacific, are the oldest known artifacts of their kind in the world.

Feral horses have roamed freely across the island of Assateague off the coast of Maryland and Virginia for hundreds of years, but exactly how they got there has remained a mystery. In a new study, ancient DNA extracted from a 16th century cow tooth from one of Spain's first Caribbean colonies turns out to be from a horse. Analysis of the DNA suggest that old folk tales claiming that horses were marooned on Assateague following the shipwreck of a Spanish galleon are likely more fact than fiction.

A newly identified 16th century horse specimen is among the oldest domestic horses from the Americas known to date, and its DNA helps clarify the history of horses in the Western Hemisphere, according to a new study.

Beaver fur was a symbol of wealth and an important trade item in 10th Century Denmark, according to a new study.

A method known as quantum key distribution has long held the promise of communication security unattainable in conventional cryptography. An international team of scientists has now demonstrated experimentally, for the first time, an approach to quantum key distribution that is based on high-quality quantum entanglement -- offering much broader security guarantees than previous schemes.

An international team has successfully implemented an advanced form of quantum cryptography for the first time. Moreover, encryption is independent of the quantum device used and therefore even more secure against hacking attempts.

Several 1700 years old decorative mosaic floors have been excavated in a luxury villa located in present-day Turkey, once overlooking the Mediterranean Sea. New chemical analyzes reveal that recycled glass was used in laying the mosaic floors.

Many people and companies worry about sensitive data getting hacked, so encrypting files with digital keys has become more commonplace. Now, researchers have developed a durable molecular encryption key from sequence-defined polymers that are built and deconstructed in a sequential way. They hid their molecular key in the ink of a letter, which was mailed and then used to decrypt a file with text from a classic story.
