Even treated wood prevents bacterial transmission by hand      (via sciencedaily.com)     Original source 

According to a new study, surface treatment and moisture affect the antibacterial properties of wood. Based on the findings, treated wood should be increasingly used as surface material.

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.

New study finds hidden trees across Europe: A billion tons of biomass is overlooked today      (via sciencedaily.com)     Original source 

Through satellite imaging a new AI driven mapping of biomass and CO2 storage shows that a huge number of trees are overlooked in Europe's urban, rural, and agricultural areas. Across Europe, researchers have discovered a billion tons of hidden biomass.

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.

Plants transformed into detectors of dangerous chemicals      (via sciencedaily.com)     Original source 

What if your house plant could tell you your water isn't safe? Scientists are closer to realizing this vision, having successfully engineered a plant to turn beet red in the presence of a banned, toxic pesticide.

Yeast speeds discovery of medicinal compounds in plants      (via sciencedaily.com)     Original source 

Researchers have harnessed the power of baker's yeast to create a cost-effective and highly efficient approach for unraveling how plants synthesize medicinal compounds, and used the new method to identify key enzymes in a kratom tree.

Evolutionary secrets of 'Old Tom' and the killer whales of Eden revealed by genetic study      (via sciencedaily.com)     Original source 

Evolutionary biologists have for the first time decoded the genetic lineage of a famous killer whale and a pod that once worked alongside whale hunters off the coast of Australia. In the Australian tradition of claiming New Zealand's celebrities as its own, Old Tom, the leader of a pod of killer whales that famously helped whalers hunt baleen whales in the 20th century, has ancestral links to modern-day killer whales in New Zealand, according to new DNA research. Old Tom also shared a common ancestor with killer whales from Australasia, the North Pacific, and North Atlantic Oceans, but is most similar to modern New Zealand killer whales. However, most of Tom's DNA code is not found in other killer whales globally suggesting that the killer whales of Eden may have become extinct locally.

Survival of the newest: the mammals that survive mass extinctions aren't as 'boring' as scientists thought      (via sciencedaily.com)     Original source 

For decades, scientists have assumed that mammals and their relatives that survived challenging times (like those during mass extinctions) made it because they were generalists that were able to eat just about anything and adapt to whatever life threw at them. A new study into the mammal family tree through multiple mass extinctions revealed that the species that survived aren't as generic as scientists had thought: instead, having new and different traits can be the key to succeeding in the aftermath of a catastrophe.

Carbon-capture tree plantations threaten tropical biodiversity for little gain, ecologists say      (via sciencedaily.com)     Original source 

The increasingly urgent climate crisis has led to a boom in commercial tree plantations in an attempt to offset excess carbon emissions. However, authors argue that these carbon-offset plantations might come with costs for biodiversity and other ecosystem functions. Instead, the authors say we should prioritize conserving and restoring intact ecosystems.

Study on mysterious Amazon porcupine can help its protection      (via sciencedaily.com)     Original source 

A recent study sheds new light on the elusive Roosmalens' dwarf porcupine, a poorly understood neotropical species. After 22 years of relative obscurity, this research uncovers vital information about its distribution, phylogenetics, and potential conservation threats, not only revealing its endemic presence in the Madeira biogeographical province but also expanding its known range in the southern Amazon.

Timing plant evolution with a fast-ticking epigenetic clock      (via sciencedaily.com)     Original source 

Recent discoveries in the field of epigenetics, the study of inheritance of traits that occur without changing the DNA sequence, have shown that chronological age in mammals correlates with epigenetic changes that accumulate during the lifetime of an individual. In humans, this observation has led to the development of epigenetic clocks, which are now extensively used as biomarkers of aging. While these clocks work accurately from birth until death, they are set back to zero in each new generation. Now, an international team shows that epigenetic clocks not only exist in plants, but that these clocks keep ticking accurately over many generations.

Wild Asian elephants display unique puzzle solving skills      (via sciencedaily.com)     Original source 

A new study has documented the abilities of individual wild Asian elephants to access food by solving puzzles that unlocked storage boxes. It is the first research study to show that individual wild elephants have different willingness and abilities to problem solve in order to get food.

Why are killer whales harassing and killing porpoises without eating them?      (via sciencedaily.com)     Original source 

For decades, fish-eating killer whales in the Pacific Northwest have been observed harassing and even killing porpoises without consuming them —- a perplexing behavior that has long intrigued scientists.
