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.

Did you know that physical activity can protect you from chronic pain?      (via sciencedaily.com)     Original source 

Reserachers found that people who were more active in their free time had a lower chance of having various types of chronic pain 7-8 years later. For example, being just a little more active, such as going from light to moderate activity, was associated with a 5% lower risk of reporting some form of chronic pain later. For severe chronic pain in several places in the body, higher activity was associated with a 16% reduced risk. The researchers found that the ability to tolerate pain played a role in this apparent protective effect. That explains why being active could lower the risk of having severe chronic pain, whether or not it was widespread throughout the body.

Combination of the climate crisis and continued deforestation may result in significant damage to the animal world      (via sciencedaily.com)     Original source 

A new study states that the combination of global warming and extreme heat events, alongside the continued expansion of deforestation in the world, may be devastating for many species of animals, especially those that know how to climb trees. As part of the study, the researchers focused on lizards and showed that following the effects of climate change, they will seek refuge from the hot ground by spending a lot of time on trees. However, due to human-related activities, such as deforestation, urbanization and the expansion of agricultural lands at the expense of natural lands, the availability of trees in the areas where the lizards live will decrease, and this may lead to the collapse of many populations.

Astronomers unveil strong magnetic fields spiraling at the edge of Milky Way's central black hole      (via sciencedaily.com)     Original source 

A new image from the Event Horizon Telescope (EHT) collaboration has uncovered strong and organized magnetic fields spiraling from the edge of the supermassive black hole Sagittarius A* (Sgr A*). Seen in polarized light for the first time, this new view of the monster lurking at the heart of the Milky Way Galaxy has revealed a magnetic field structure strikingly similar to that of the black hole at the center of the M87 galaxy, suggesting that strong magnetic fields may be common to all black holes.

Distant 'space snowman' unlocks mystery of how some dormant deep space objects become 'ice bombs'      (via sciencedaily.com)     Original source 

Researchers found that the double-lobed object, which is officially named Kuiper Belt Object 486958 Arrokoth and resembles a snowman, may have ancient ices stored deep within it from when the object first formed billions of years ago.

A decade of aphantasia research: what we've learned about people who can't visualize      (via sciencedaily.com)     Original source 

People who can't visualize an image in their mind's eye are less likely to remember the details of important past personal events or to recognize faces, according to a review of nearly ten years of research. People who cannot bring to mind visual imagery are also less likely to experience imagery of other kinds, like imagining music, according to new research by the academic who first discovered the phenomenon.

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.

'Cosmic cannibals' expel jets into space at 40 percent the speed of light      (via sciencedaily.com)     Original source 

Astronomers have measured the speed of fast-moving jets in space, crucial to star formation and the distribution of elements needed for life. The jets of matter, expelled by stars deemed 'cosmic cannibals', were measured to travel at over one-third of the speed of light -- thanks to a groundbreaking new experiment.

Astronomers have concluded that an obscure class of galaxies known as Compact Symmetric Objects, or CSOs, are not young as previously thought but rather lead relatively short lives.

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.

New maps help decision-makers factor albedo into tree-planting decisions      (via sciencedaily.com)     Original source 

A new study provides a global analysis of where restoration of tree cover is most effective at cooling the global climate system, considering not just the cooling from carbon storage but also the warming from decreased albedo. The researchers provide a tool practitioners and land managers can use to determine just how much of a problem albedo is for any reforestation or afforestation project on the globe.
