An anticounterfeiting smart label and security platform which makes forgery fundamentally impossible has been proposed. The device accomplishes this by controlling a variety of information of light including the color, phase, and polarization in one optical device.

A new study has revealed that over the last 20,000 to 50,000 years, birds have undergone a major extinction event, inflicted chiefly by humans, which caused the disappearance of about 10 to 20 percent of all avian species. According to the researchers, the vast majority of the extinct species shared several features: they were large, they lived on islands, and many of them were flightless.

Research on a newly discovered bird fossil found that a unique brain shape may be why the ancestors of living birds survived the mass extinction that claimed all other known dinosaurs.

Newly-hatched pterosaurs may have been able to fly but their flying abilities may have been different from adult pterosaurs, according to a new study. Researchers found that hatchling humerus bones were stronger than those of many adult pterosaurs, indicating that they would have been strong enough for flight.

New findings from zoologists working with birds in Southeast Asia are shining fresh light on the connections between animal behaviour, geology, and evolution - underlining that species can diversify surprisingly quickly under certain conditions. Sulawesi Babblers (Pellorneum celebense), shy birds that live in the undergrowth on Indonesian islands, have begun to diverge quite significantly despite being separated geographically for mere tens of thousands of years.

Quantum computers have been one-of-a-kind devices that fill entire laboratories. Now, physicists have built a prototype of an ion trap quantum computer that can be used in industry. It fits into two 19-inch server racks like those found in data centers throughout the world. The compact, self-sustained device demonstrates how this technology will soon be more accessible.

Researchers have turned a longstanding challenge in DNA data storage into a tool, using it to offer users previews of stored data files -- such as thumbnail versions of image files.

Microphones are perhaps the most common electronic sensor in the world, with an estimated 320 million listening for our commands in the world's smart speakers. The trouble is that they're capable of hearing everything else, too.

Ancient chickens lived significantly longer than their modern equivalents because they were seen as sacred -- not food -- archaeologists have found.

Free from human disturbance for a century, an inland island in Central America has nevertheless lost more than 25% of its native bird species since its creation as part of the Panama Canal's construction, and scientists say the losses continue.

As more private data is stored and shared digitally, researchers are exploring new ways to protect data against attacks from bad actors. Current silicon technology exploits microscopic differences between computing components to create secure keys, but artificial intelligence (AI) techniques can be used to predict these keys and gain access to data. Now, researchers have designed a way to make the encrypted keys harder to crack.

If paleontologists had a wish list, it would almost certainly include insights into two particular phenomena: how dinosaurs interacted with each other and how they began to fly.

Coded messages in invisible ink sound like something only found in espionage books, but in real life, they can have important security purposes. Yet, they can be cracked if their encryption is predictable. Now, researchers have printed complexly encoded data with normal ink and a carbon nanoparticle-based invisible ink, requiring both UV light and a computer that has been taught the code to reveal the correct messages.

Scientists have developed algorithms that more efficiently measure how difficult it would be for an attacker to guess secret keys for cryptographic systems. The approach could reduce the computational complexity needed to validate encryption security.

A team o computer science researchers has uncovered a line of attack that breaks all Spectre defenses, meaning that billions of computers and other devices across the globe are just as vulnerable today as they were when Spectre was first announced.

A new article argues that the ability to move forward on developing useful quantum computers requires new major advances in materials science, engineering and fabrication. The authors call for new approaches from broad areas of science and engineering.

Researchers have developed a method to change a cellular material's fundamental topology at the microscale.

New research looked at a newly discovered, endangered songbird located only in South America -- the Iberá Seedeater -- and found that this bird followed a very rare evolutionary path to come into existence at a much faster pace than the grand majority of species.

Ancient Egyptians mummified cats, dogs, ibises and other animals, but closer to home in the South American Atacama desert, parrot mummies reveal that between 1100 and 1450 CE, trade from other areas brought parrots and macaws to oasis communities, according to an international and interdisciplinary team.

Feathers, an owl head and oars suggest the people in this Iron Age grave were prepared for a long journey.
