New research suggests that determining evolutionary trees of organisms by comparing anatomy rather than gene sequences is misleading. The study shows that we often need to overturn centuries of scholarly work that classified living things according to how they look.

Paleontologists have debated whether dinosaurs were warm-blooded, like modern mammals and birds, or cold-blooded, like modern reptiles. In a new paper, scientists are unveiling a new method for studying dinosaurs' metabolic rates, using clues in their bones.

While quantum computers offer many novel possibilities, they also pose a threat to internet security since these supercomputers make common encryption methods vulnerable. Based on the so-called quantum key distribution, researchers have developed a new, tap-proof communication network.

Scientists settle debate surrounding species that laid eggs exploited by early Australian people around 50,000 years ago. Shell proteins point to Genyornis, which was among the 'mega-fauna' to go extinct a few thousand years after humans arrived on the continent.

A laser pulse that sidesteps the inherent symmetry of light waves could manipulate quantum information, potentially bringing us closer to room temperature quantum computing.

Researchers shed light on the way Quetzalcoatlus would have flown, finding that the dinosaur's flying dynamics were actually very different to how it has been depicted in popular culture.

Jars of tiny platypus and echidna specimens, collected in the late 1800s by the scientist William Caldwell, have been discovered in the stores of Cambridge's University Museum of Zoology.

Researchers have examined the mass extinction of large animals over the past tens of thousands of years and found that extinct species had, on average, much smaller brains than species that survived.

Researchers have developed a single-material, single-stimuli microstructure that can outmaneuver even living cilia. These programmable, micron-scale structures could be used for a range of applications, including soft robotics, biocompatible medical devices, and even dynamic information encryption.

A new form of security identification could soon see the light of day and help us protect our data from hackers and cybercriminals. Quantum mathematicians have solved a mathematical riddle that allows for a person's geographical location to be used as a personal ID that is secure against even the most advanced cyber attacks.

Human-related extinctions of the largest herbivores and carnivores are disrupting what appears to be a fundamental feature of past and present ecosystems, says a new study.

Crows and ravens have great flying ability, which allows them to gain access to new places more easily. While these skills were key to their success, new research also shows that big bodies and big brains played an important role in helping crows and ravens survive in the new climates they occupied.

Palaeontologists have discovered remarkable new evidence that pterosaurs, the flying relatives of dinosaurs, were able to control the color of their feathers using melanin pigments.

The first large-scale study of its kind has uncovered more than 4,000 years' worth of distinctive foraging behavior in a species once driven to the brink of extinction.

A new study combining records of climate change during the last 3.5 million years with fossil evidence of mammals in Africa reveals that times of erratic climate change are not followed by major upheavals in evolution.

One of the most contentious questions in evolutionary biology is, how did the Amazon become so rich in species? A new study focused on birds examines how the movements of rivers in the Amazon have contributed to that area's exceptional biological diversity. The researchers found that as small river systems change over time, they spur the evolution of new species. The findings also reveal previously unknown bird species in the Amazon that are only found in small areas next to these dynamic river systems, putting them at high risk.

Researchers have developed a technique that leverages hardware and software to improve file system security for next-generation memory technologies called non-volatile memories (NVMs). The new encryption technique also permits faster performance than existing software security technologies.

As personal health records (AKA patient portals) allowing patients to see test results, medications and other health information gain in popularity, scientists studied cancer patients' and doctors' differing perceptions of this tool. Patients cited potential for personal health records to deepen their relationship with their healthcare provider and to allow them to be more understood. Physicians were interested in having more clinical information sharing to facilitate better patient care.

Prehistoric mammals bulked up, rather than develop bigger brains, to boost their survival chances once dinosaurs had become extinct, research suggests.

Researchers describe new high-purity single-photon source that can operate at room temperature. The source is an important step toward practical applications of quantum technology, such as highly secure communication based on quantum key distribution (QKD).
