Discovery of mechanism plants use to change seed oil could impact industrial, food oils      (via sciencedaily.com)     Original source 

Researchers have discovered a new mechanism of oil biosynthesis and found a way to genetically engineer a type of test plant to more efficiently produce different kinds of seed oil that it otherwise wouldn't make. While the engineering is proof-of-concept, this discovery could lead to improved production of valuable oils used in food and by a range of industries. The modified plant overcame metabolic bottlenecks and produced significant amounts of an oil similar to castor oil that it doesn't naturally produce.

Trotting robots reveal emergence of animal gait transitions      (via sciencedaily.com)     Original source 

A four-legged robot trained with machine learning has learned to avoid falls by spontaneously switching between walking, trotting, and pronking -- a milestone for roboticists as well as biologists interested in animal locomotion.

The double-fanged adolescence of saber-toothed cats      (via sciencedaily.com)     Original source 

How did North America's saber-toothed cats hunt without breaking their unwieldy saber-like canines, which are vulnerable to sideways bending stresses? A paleontologist provides mechanical evidence that during adolescence, when young cats were learning to hunt, their baby teeth remained in place for up to 30 months to laterally buttress the emerging permanent sabers. By the time the baby teeth fell out, presumably the adult cat knew how to protect its sabers during attacks.

Fading lights: Multiple threats to North America's firefly populations      (via sciencedaily.com)     Original source 

Scientists have applied a data-driven approach to understanding firefly population dynamics on a continental scale. Key findings from this new study indicate that fireflies, part of the beetle order, are sensitive to various environmental factors, from short-term weather conditions to longer climatic trends, including the number of growing-degree days related to temperature accumulations.

Long snouts protect foxes when diving headfirst in snow      (via sciencedaily.com)     Original source 

When hunting for mice in winter, red and arctic fox are known to plunge headfirst at speeds of 2-4 meters per second, but their sharp noses reduce the impact force in snow and protect them from injury, according to a new study.

Possible alternative to antibiotics produced by bacteria      (via sciencedaily.com)     Original source 

Many bacteria produce substances to gain an advantage over competitors in their highly competitive natural environment. Researchers have discovered a new so-called lantibiotic, namely epilancin A37. It is produced by staphylococci that colonize the skin and acts specifically against their main competitors there, the corynebacteria. This specificity is presumably mediated by a very special mechanism of action, which the researchers were able to decipher in detail.

Details of hurricane Ian's aftermath captured with new remote sensing method      (via sciencedaily.com)     Original source 

Using aerial imagery data and LiDAR, a study remotely identified the hardest-hit areas of Southwest Florida's Estero Island in the aftermath of Hurricane Ian. Researchers estimated the extent of structural damage and compared pre- and post-storm beach structural changes. They identified 2,427 structures that were impacted. The value of the heavily damaged structures was estimated at more than $200 million. The study has applied an advanced multi-faceted approach that links damage assessment to post-storm change in the structure of barrier islands.

Fixin' to be flexitarian: Scrap fish and invasive species can liven up vegetables      (via sciencedaily.com)     Original source 

Greening the way we eat needn't mean going vegetarian. A healthy, more realistic solution is to adopt a flexitarian diet where seafoods add umami to 'boring' vegetables. A gastrophysicist puts mathematical equations to work in calculating the umami potential of everything from seaweed and shrimp paste to mussels and mackerel.

Study details a common bacterial defense against viral infection      (via sciencedaily.com)     Original source 

Researchers report on the molecular assembly of one of the most common anti-phage systems -- from the family of proteins called Gabija -- that is estimated to be used by at least 8.5%, and up to 18%, of all bacteria species on Earth.

Mobile device location data is already used by private companies, so why not for studying human-wildlife interactions      (via sciencedaily.com)     Original source 

When did you last go anywhere without your cell phone? From maps and weather apps to social media platforms, we give consent for our phones to trace our footsteps and behavior. These curated mobility data are often used for personalized advertisements. Scientists now argue mobility data can offer so much more -- it is key to understanding human-wildlife interactions for guiding policy decisions on sustainability-related issues and should be free and accessible for research.

Ancient Maya blessed their ballcourts      (via sciencedaily.com)     Original source 

Using environmental DNA analysis, an international team of researchers identified a collection of plants used in ceremonial rituals in the ancient Maya city of Yaxnohcah in Mexico. The plants, known for their religious associations and medicinal properties, were discovered beneath a plaza floor where a ballcourt was built.

Could fishponds help with Hawaii's food sustainability?      (via sciencedaily.com)     Original source 

Indigenous aquaculture systems in Hawaii, known as loko i'a or fishponds, can increase the amount of fish and fisheries harvested both inside and outside of the pond. Today, aquaculture supplies less than 1% of Hawaii's 70 million pounds of locally available seafood, but revitalization of loko i'a has the potential to significantly increase locally available seafood.
