Giant fossil's 'bird-brain'      (via sciencedaily.com) 

The largest flightless bird ever to live weighed in up to 600kg and had a whopping head about half a meter long - but its brain was squeezed for space. Dromornis stirtoni, the largest of the 'mihirungs' (an Aboriginal word for 'giant bird'), stood up to 3m and had a cranium wider and higher than it was long due to a powerful big beak, leading Australian palaeontologists to look inside its brain space to see how it worked.

Facial recognition ID with a twist: Smiles, winks and other facial movements for access      (via sciencedaily.com) 

Concurrent Two-Factor Identity Verification requires both one's facial identity and a specific facial motion to gain access. To set it up, a user faces a camera and records a short 1-2 second video of either a unique facial motion or a lip movement from reading a secret phrase. The video is then input into the device, which extracts facial features and the features of the facial motion, storing them for later ID verification.

Quartz crystals in the stomach of fossil bird complicates the mystery of its diet      (via sciencedaily.com) 

The fossil of a bird that lived alongside the dinosaurs was found with some sort of rocks in its stomach. Previously, researchers thought that these rocks were swallowed on purpose to help clean its stomach, like modern birds of prey do, giving a hint at its diet. But in a new study, scientists discovered that these rocks are quartz crystals that likely formed after the bird died -- its diet is still a mystery.

Fossil pigments shed new light on vertebrate evolution      (via sciencedaily.com) 

This new paper shows that melanin is more than just something that gives colour to the body. It played an important role in the evolution of warm-blooded animals and helped defined what birds and mammals look like today. By studying where melanin occurs in the body in fossils and modern animals researchers have produced the first model for how melanin has evolved over the last 500 million years.

Say goodbye to the dots and dashes to enhance optical storage media      (via sciencedaily.com) 

A new technology is aimed at modernizing the optical digital storage technology. This advancement allows for more data to be stored and for that data to be read at a quicker rate. Rather than using the traditional dots and dashes as commonly used in these technologies, the innovators encode information in the angular position of tiny antennas, allowing them to store more data per unit area.

Two-dimensional materials, consisting of a single layer of atoms, have been booming in research for years. They possess novel properties that can only be explained with the help of the laws of quantum mechanics. Researchers have now used ultracold atoms to gain new insights into previously unknown quantum phenomena. They found out that the magnetic orders between two coupled thin films of atoms compete with each other.

Archaeopteryx fossil provides insights into the origins of flight      (via sciencedaily.com) 

Molting is thought to be unorganized in the first feathered dinosaurs because they had yet to evolve flight, so determining how molting evolved can lead to better understanding of flight origins. Recently researchers discovered that the earliest record of feather molting from the famous early fossil bird Archaeopteryx found in southern Germany in rocks that used to be tropical lagoons ~150 million years ago.
