AI writing, illustration emits hundreds of times less carbon than humans, study finds      (via sciencedaily.com)     Original source 

A group of scholars calculated the amount of energy used by AI tools for the tasks of writing and illustrating and compared it to the average amount of energy humans use for the same processes. Their results showed artificial intelligence results in hundreds of times less carbon emissions than humans. This does not mean, however, that AI can or should replace humans in those tasks, simply that its energy usage is less. The better approach is a partnership between humans and AI, the authors write.

Robot, can you say 'cheese'?      (via sciencedaily.com)     Original source 

What would you do if you walked up to a robot with a human-like head and it smiled at you first? You'd likely smile back and perhaps feel the two of you were genuinely interacting. But how does a robot know how to do this? Or a better question, how does it know to get you to smile back?

Rock-wallaby bite size ‘packs a punch’      (via sciencedaily.com)     Original source 

Australian rock-wallabies are 'little Napoleons' when it comes to compensating for small size, packing much more punch into their bite than larger relatives. Researchers made the discovery while investigating how two dwarf species of rock-wallaby are able to feed themselves on the same kinds of foods as their much larger cousins.

Scientists extract genetic secrets from 4,000-year-old teeth to illuminate the impact of changing human diets over the centuries      (via sciencedaily.com)     Original source 

Researchers have recovered remarkably preserved microbiomes from two teeth dating back 4,000 years, found in an Irish limestone cave. Genetic analyses of these microbiomes reveal major changes in the oral microenvironment from the Bronze Age to today. The teeth both belonged to the same male individual and also provided a snapshot of his oral health.

Milk on ice: Antarctic time capsule of whole milk powder sheds light on the enduring qualities--and evolution--of dairy products past and present      (via sciencedaily.com)     Original source 

In a remarkable discovery, whole milk powder manufactured in New Zealand in 1907 and transported to Antarctica with explorers seeking the South Pole was unveiled after more than a century. The find has allowed dairy researchers to answer the question: Is the milk we enjoy today different from the milk consumed in previous generations? Now, a new comparative study has peered back in time to demonstrate that -- despite advancements in selective breeding and changes to farm practices -- milk of the past and milk today share more similarities than differences and are still crucial building blocks of human nutrition.

Micro-Lisa! Making a mark with novel nano-scale laser writing      (via sciencedaily.com)     Original source 

High-power lasers are often used to modify polymer surfaces to make high-tech biomedical products, electronics and data storage components. Now researchers have discovered a light-responsive, inexpensive sulfur-derived polymer is receptive to low power, visible light lasers -- promising a more affordable and safer production method in nanotech, chemical science and patterning surfaces in biological applications.

Wild bird gestures 'after you'      (via sciencedaily.com)     Original source 

A small-bird species, the Japanese tit (Parus minor), uses wing movements as a gesture to convey the message 'after you,' according to new research. When a mating pair arrives at their nest box with food, they will wait outside on perches. One will then often flutter its wings toward the other, apparently indicating for the latter to enter first. The researchers say that this discovery challenges the previous belief that gestural communication is prominent only in humans and great apes, significantly advancing our understanding of visual communication in birds.

Signs of life would be detectable in single ice grain emitted from extraterrestrial moons      (via sciencedaily.com)     Original source 

Could life be found in frozen sea spray from moons orbiting Saturn or Jupiter? New research finds that life can be detected in a single ice grain containing one bacterial cell or portions of a cell. The results suggest that if life similar to that on Earth exists on these planetary bodies, that this life should be detectable by instruments launching in the fall.

Tudor era horse cemetery in Westminster revealed as likely resting place for elite imported animals      (via sciencedaily.com)     Original source 

Archaeological analysis of a near unique animal cemetery discovered in London nearly 30 years ago has revealed there was an international horse trading network, orchestrated by the elites of late medieval and Tudor England, which brought superior physical specimens to the UK for jousting and for use as status symbols.
