(GigaScience) Researchers provide genome sequences for 5 birds-of-paradise species: 3 without previous genome data and 2 with improved data. Birds-of-paradise are classic examples of extreme sexual selection due to generations of females choosing mates based on ‘attractiveness’. The result is unparalleled species radiation with males exhibiting vast differences in behavior and an array of exotic feathers. Analyses identified genes potentially involved in feather characteristics, and the sequences will serve as a rich resource for evolution studies.
(North Carolina State University) An international team of researchers has performed molecular analysis on fossil feathers from a small, feathered dinosaur from the Jurassic. Their research could aid scientists in pinpointing when feathers evolved the capacity for flight during the dinosaur-bird transition.
(Temple University College of Science and Technology) In a race against time, an American professor and a Haitian CEO have teamed up to establish private nature reserves to protect Haiti’s disappearing species. Now, with funding from Global Wildlife Conservation and Rainforest Trust, the first such park has been purchased: Grand Bois, a mountain in the southwest of Haiti with rare and endangered plants and animals.
(AKSON Russian Science Communication Association) Russian scientists studied abandoned arable land in the European part of Russia where temperate forests grow. The study showed that trees start to grow on the abandoned fields immediately after the land has been withdrawn from agricultural use. As it turned out, the presence or absence of grass fires in a given area plays a key role in the stages and rate of overgrowth. The results are published in Ecological Processes.
Chickens that are genetically modified to produce human proteins in their eggs can offer a cost-effective method of producing certain types of drugs, research suggests. Researchers say the findings provide sound evidence for using chickens as a cheap method of producing high quality drugs for use in research studies and, potentially one day, in patients.
Obesity, climate change, and malnutrition are among the greatest global crises facing our world today. Wouldn’t it be great if there were solutions to tackle all three problems at once? That might sound far-fetched. But a new report, published Sunday…
Four days ago, I received a notification from the Bend City Code Enforcement essentially kicking my family and I out of our home of four years. I am married, and have two daughters- 3 and 5. Our dream of living in a tiny house started five years ago, as I […]
