Fruit, nectar, bugs and blood: How bat teeth and jaws evolved for a diverse dinnertime      (via sciencedaily.com)     Original source 

Noctilionoid bat species evolved wildly different faces as they adapted to exploit diverse food sources -- including insects, fruit, nectar, blood and fish. New research shows that those adaptations include dramatic, but also consistent, modifications to tooth number, size, shape and position.

Energy-saving AI chip      (via sciencedaily.com)     Original source 

A computer scientist has developed an AI-ready architecture that is twice as powerful as comparable in-memory computing approaches. The researcher applies a new computational paradigm using special circuits known as ferroelectric field effect transistors (FeFETs). Within a few years, this could prove useful for generative AI, deep learning algorithms and robotic applications.

Engineers develop breakthrough 'robot skin'      (via sciencedaily.com)     Original source 

Smart, stretchable and highly sensitive, a new soft sensor opens the door to a wide range of applications in robotics and prosthetics. When applied to the surface of a prosthetic arm or a robotic limb, the sensor skin provides touch sensitivity and dexterity, enabling tasks that can be difficult for machines such as picking up a piece of soft fruit. The sensor is also soft to the touch, like human skin, which helps make human interactions safer and more lifelike.

A new era for accurate, rapid COVID-19 testing      (via sciencedaily.com)     Original source 

Researchers demonstrate a nanopore-based technique that can detect different variants of SARS-CoV-2, the virus that causes COVID-19. The method was very effective in detecting the Omicron variant of the virus in the saliva of people with COVID-19.

Roosters might recognize themselves in the mirror      (via sciencedaily.com)     Original source 

Scrape, cluck, lay eggs -- that's it? Anyone involved in chicken farming knows that the animals are capable of much more. Researchers have found evidence that roosters could recognize themselves in a mirror. Whether this is successful, however, depends on the experimental conditions -- a finding that points beyond the experiment with roosters and could also be of importance for other animal species.

To navigate the world, we all shimmy like these electric fish      (via sciencedaily.com)     Original source 

An electric knifefish shimmies in the water for the same reason a dog sniffs or a human glances around a new place -- to make sense of their surroundings. For the first time, scientists demonstrate that a wide range of organisms, even microbes, perform the same pattern of movements in order to sense the world.

Research reveals three new marsupial species -- though all likely extinct      (via sciencedaily.com)     Original source 

The exciting discovery of three new species of a small Australian marsupial has been tempered by the sad fact that each of the newly identified species of mulgara is likely already extinct.

Bacteria can enhance host insect's fertility with implications for disease control      (via sciencedaily.com)     Original source 

New research reveals how the bacteria strain Wolbachia pipientis enhances the fertility of the insects it infects, an insight that could help scientists increase the populations of mosquitoes that do not carry human disease.

Raining cats and dogs: Global precipitation patterns a driver for animal diversity      (via sciencedaily.com)     Original source 

A team has identified several factors to help answer a fundamental ecological question: why is there a ridiculous abundance of species some places on earth and a scarcity in others? What factors, exactly, drive animal diversity? They discovered that what an animal eats (and how that interacts with climate) shapes Earth's diversity.

Finding the genes that help kingfishers dive without hurting their brains      (via sciencedaily.com)     Original source 

Scientists studied the genomes of 30 kingfisher species to try to identify the genes that allow kingfishers to dive headfirst into water without huring their brains. The researchers found that the diving birds have unusual mutations to the genes that produce tau: a protein that helps stabilize tiny structures in the brain, but which can build up in humans with traumatic brain injuries or Alzheimer's disease. The researchers suspect that these variations in the kingfishers' tau proteins might protect their brains when they dive.

Scientists uncover cause of mysterious deaths of elephants in Zimbabwe      (via sciencedaily.com)     Original source 

A bacterium, closely associated with deadly septicaemia, could have caused the deaths of six African elephants in Zimbabwe and possibly more in neighboring countries. The findings place infectious diseases on the list of pressures on African elephants, whose populations continue to be under threat.

Origin of ancient mummified baboons found in Egypt      (via sciencedaily.com)     Original source 

Primatologists are using genetic analysis to determine the geographic origin of ancient mummified baboons found in Egypt. The team finds evidence that the two legendary trading regions of Punt and Adulis may have been the same place separated by a thousand years of history.

Plant-based materials give 'life' to tiny soft robots      (via sciencedaily.com)     Original source 

A team of researchers has created smart, advanced materials that will be the building blocks for a future generation of soft medical microrobots. These tiny robots have the potential to conduct medical procedures, such as biopsy, and cell and tissue transport, in a minimally invasive fashion.

Dingoes given 'almost-human' status in pre-colonial Australia      (via sciencedaily.com)     Original source 

It's said that a dog is a man's best friend, but the wild dingo is much maligned in Australia. This may not always have been the case though, with new research suggesting that dingoes were buried -- and even domesticated -- by First Nations people prior to European colonization.

Heat waves harm bird reproduction on agricultural lands      (via sciencedaily.com)     Original source 

The effects of extreme temperatures on avian reproduction can vary depending on the type of environment that birds call home. A new study found that extreme high temperatures significantly diminish bird reproductive success in agricultural landscapes.

Pinpointing the emergence of muddy flavors in your fish      (via sciencedaily.com)     Original source 

Many people have experienced a muddy off-flavor in farmed fish. While the aquaculture industry has known about the problem for 20 years, it continues to impact the consumption of otherwise healthy and potentially sustainable fish. Now, researchers have been able to pinpoint exactly when the off-flavors emerge. And this can make it easier to deal with the compounds that turn people away from farmed fish.
