Surveilling wetlands for infectious bird flu -- and finding it      (via sciencedaily.com)     Original source 

Recently, morning omelets and holiday dinners have gotten more expensive. One likely cause is bird flu, outbreaks of which led to the deaths of millions of chickens and turkeys from infection or culling in 2022, according to the U.S. Department of Agriculture, and which still demands rigorous monitoring of wild populations. Now, researchers have developed a method that detected infectious bird flu virus in wetlands frequented by waterfowl.

Dangerous bee virus less deadly in at least one US forest      (via sciencedaily.com)     Original source 

Researchers have found that the deadly deformed wing virus (DMV) in bees may have evolved to be less deadly in at least one U.S. forest. The findings could have implications for preventing or treating the virus in managed colonies, researchers said.

Non-native species likely to continue spreading in North America, Australia and Europe      (via sciencedaily.com)     Original source 

Naturalized species, which are not native but have established themselves in new locations, have the potential to spread even further to suitable habitats in many parts of the world, reports a new study.

Study sheds light on how Earth cycles fossil-carbon      (via sciencedaily.com)     Original source 

Researches used rhenium as a proxy for fossil carbon in order to quantify the rate at which Earth naturally releases carbon dioxide into the atmosphere and found that high rates of carbon breakdown persist across the different geographical profiles of a river basin.

New study reveals surprising insights into feeding habits of carnivorous dinosaurs in North America      (via sciencedaily.com)     Original source 

New research sheds light on the dining habits of ancient carnivorous dinosaurs from Jurassic rocks of the USA. A recent study explores the bite marks left on the ancient bones of the giant long-necked sauropod dinosaurs like Diplodocus and Brontosaurus by carnivorous theropod dinosaurs.

Recreation of ancient seawater reveals which nutrients shaped the evolution of early life      (via sciencedaily.com)     Original source 

Scientists know very little about conditions in the ocean when life first evolved, but new research has revealed how geological processes controlled which nutrients were available to fuel their development.

Found at last: Bizarre, egg-laying mammal finally rediscovered after 60 years      (via sciencedaily.com)     Original source 

A long-beaked echidna named after Sir David Attenborough and last seen by scientists in 1961 has been photographed for the first time in an Indonesian tropical forest. An international team of researchers worked with local communities to deploy over 80 camera traps to film the elusive animal. Besides rediscovering the echidna, the team uncovered a wealth of species completely new to science, including beetles, spiders, and a remarkable tree-dwelling shrimp.

Palaeo-CSI: Mosasaurs were picky eaters      (via sciencedaily.com)     Original source 

Mosasaurs, those large marine reptiles from the long-gone Cretaceous world, were quite picky in their choice of diet. Researchers came to this conclusion after studying the wear marks on mosasaur teeth.

Yeast with an over half synthetic genome is created in the lab      (via sciencedaily.com)     Original source 

Researchers have combined over seven synthetic chromosomes that were made in the lab into a single yeast cell, resulting in a strain with more than 50% synthetic DNA that survives and replicates similarly to wild yeast strains. A global consortium is working to develop the first synthetic eukaryote genome from scratch. The team has now synthesized and debugged all sixteen yeast chromosomes.

Why a surprising discovery, warming seas and the demise of the 'Meg' may spell trouble for more and more sharks      (via sciencedaily.com)     Original source 

Some unexpected shark strandings and subsequent surprises following autopsies have, ironically, taken marine biologists millions of years back in time as they look to the future with concern. Adding chapters to an evolutionary tale involving the infamous megalodon shark (the 'Meg'), they think their work suggests there are more warm-blooded sharks out there than previously believed, and -- based on the Meg's demise -- these species may be at great risk from warming seas.

Infection with common cat-borne parasite associated with frailty in older adults      (via sciencedaily.com)     Original source 

A new study of 601 older adults found that those with higher serointensity -- or a higher concentration of antibiodies -- to the cat-borne parasite Toxoplasma gondii are more likely to show signs of frailty, including exhaustion, loss of muscle mass and other indications of declining health. T. Gondii has previously been associated with risk-taking behavior and mental illness.
