Collaborative research across the country has shown that strengthening the relationship between the student and advisor can increase retention rates in engineering doctoral studies.

A recent study that examined the relationship between artificial intelligence (AI) and law enforcement underscores both the need for law enforcement agencies to be involved in the development of public policies regarding AI -- such as regulations governing autonomous vehicles -- and the need for law enforcement officers to better understand the limitations and ethical challenges of AI technologies.

Cultivation and growth of grapevines have strongly influenced European civilizations, but where the grapevine comes from and how it has spread across the globe has been highly disputed so far. In an extensive genome project, researchers have determined its origin and evolution from the wild vine to today's cultivar by analyzing thousands of vine genomes collected along the Silk Road from China to Western Europe.

The coveted metal copper and a sheltered location turned the Cypriot village of Hala Sultan Tekke into one of the most important trade hubs of the Late Bronze Age. Recent excavations confirm the importance of the Bronze Age city in the first period of international trade in the Mediterranean.

Geneticists have written new chapters in the reconstruction of pre-colonial Americas history after using DNA from the indigenous Ashaninka people from Amazonian Peru. They have discovered previously unexpected levels of genetic variation in this group and uncovered a strong hint that these people were involved in a South-to-North migration that led to the transition from an archaic to ceramic culture in the Caribbean islands.

A new study has found evidence of cheesemaking, using milk from multiple animals in Late Neolithic Poland.

Peru's first great empire, the Wari, stretched for more than a thousand miles over the Andes Mountains and along the coast from 600-1000 CE. The pottery they left behind gives archaeologists clues as to how the empire functioned. In a new study researchers showed that rather than using 'official' Wari pottery imported from the capital, potters across the empire were creating their own ceramics, decorated to emulate the traditional Wari style. To figure it out, the scientists analyzed the pottery's chemical make-up, with help from laser beams.

Researchers have discovered artefacts produced by old world monkeys in Thailand that resemble stone tools, which historically have been identified as intentionally made by early hominins. Until now, sharp-edged stone tools were thought to represent the onset of intentional stone tool production, one of the defining and unique characteristics of hominin evolution. This new study challenges long held beliefs about the origins of intentional tool production in our own lineage.

Researchers have discovered evidence of horse riding by studying the remains of human skeletons found in burial mounds called kurgans, which were between 4500-5000 years old. The earthen burial mounds belonged to the Yamnaya culture. The Yamnayans had migrated from the Pontic-Caspian steppes to find greener pastures in today's countries of Romania and Bulgaria up to Hungary and Serbia.

Some cities only last a century or two, while others last for a thousand years or more. Often, there aren't clear records left behind to explain why. Instead, archaeologists piece together clues from the cities' remains to search for patterns that help account for why certain places retained their importance longer than others.

A newly published study of a stalagmite found in Cave of the Mounds reveals previously undetected history of the local climate going back thousands of years. Researchers describe evidence for an ice age punctuated by massive and abrupt warming events across much of the Northern Hemisphere.

A large Bronze Age debris deposit in Mycenae, Greece provides important data for understanding the history of animal resources at the site, according to a new study.

A world-first model of paleoclimate and hydrology in Iran has highlighted favourable routes for Neanderthals and modern human expansions eastwards into Asia. The findings reveal that multiple humid periods in ancient Iran led to the expansions of human populations, opening dispersal route across the region, and the possible interactions of species such as Neanderthals and our own Homo sapiens.

A new study reports on genomic data from a 23,000-year-old individual who lived in what was probably the warmest place of Europe at the peak of the last Ice Age. The oldest human genome recovered from the southern tip of Spain adds an important piece of the puzzle to the genetic history of Europe.

Researchers have discovered what they believe is the earliest use of steel in Europe -- on Iberian stone pillars from the Final Bronze Age.

In 2011, scientists recorded a previously unknown feeding strategy in whales around the world. Now, researchers in Australia think they may have found evidence of this behaviour being described in ancient accounts of sea creatures, recorded more than 2,000 years ago. They believe that misunderstandings of these descriptions contributed to myths about medieval sea monsters. Whales are known lunge at their prey when feeding, but recently whales have been spotted at the surface of the water with their jaws open at right angles, waiting for shoals of fish to swim into their mouths. A clip of this strategy was captured in 2021 and went viral on Instagram. This strategy seems to work for the whales because the fish think they have found a place to shelter from predators, not realising they are swimming into danger. It's not known why this strategy has only recently been identified, but scientists speculate that it's a result of changing environmental conditions -- or that whales are being more closely monitored than ever before by drones and other modern technologies.

Scientists who study the origins and evolution of the plague have examined hundreds of ancient human teeth from Denmark, seeking to address longstanding questions about its arrival, persistence and spread within Scandinavia.

A recent excavation in Megiddo, Israel, unearthed the earliest example of a particular type of cranial surgery in the Ancient Near East -- and potentially one of the oldest examples of leprosy in the world.

Caribou have been using the same Arctic calving grounds for more than 3,000 years. Female caribou shed their antlers within days of giving birth, leaving behind a record of their annual travels across Alaska and Canada's Yukon that persists on the cold tundra for hundreds or even thousands of years. Researchers recovered antlers that have sat undisturbed on the arctic tundra since the Bronze Age.
