How insect wings evolved has puzzled biologists for over a century. Finally, a team from the Marine Biological Laboratory, Woods Hole, has shown that the insect wing evolved from an outgrowth on the crustacean leg that was incorporated into the animal's body wall.
A team co-led by a scientist at the University of California, Riverside, has developed a method to study how HIV mutates to escape the immune system in multiple individuals, which could inform HIV vaccine design.
In recent decades, researchers have found that most mammals' guts are surprisingly complex environments - home to a variety of microbial ecosystems that can profoundly affect an animal's well-being. Scientists have now learned that the bear appears to be an exception, with its gut playing host to a microbial population that varies little across the intestinal tract.
A research team co-led by a scientist at the Hong Kong University of Science and Technology has developed a method to study how HIV mutates to escape the immune system in multiple patients, which could inform HIV vaccine design.
Researchers compared how young companion dogs and companion pigs seek human proximity in a novel environment. It turned out that both dogs and pigs stay close to their owner if no other person is present; but if a stranger is also there, only dogs stay near humans, pigs prefer to stay away. The study reveals that living in a human family is not enough for early developing a general human preference in companion animals, species differences weigh in.
Human fingerprints have a self-regulating moisture mechanism that not only helps us to avoid dropping our smartphone, but could help scientists to develop better prosthetic limbs, robotic equipment and virtual reality environments, a new study reveals.
Seals native to Siberia's Lake Baikal have been found to have a remarkable adaptation in their teeth that has allowed them to prosper even in the face of limited nutrient offerings.
Two genes that are important for the diverse colors and patterns of warbler plumage have evolved through two very different processes, according to a new study led by Penn State researchers. These evolutionary processes could help explain the rapid evolution of these songbirds into so many unique species.
Innovative molecular techniques explain how corals on the east coast of Australia survived previous tough conditions--enabling the Great Barrier Reef to become the vast reef it is today. Scientists mapped the rise and fall of two coral populations on the reef, tracking which genes rapidly evolved to endure changing conditions, while measuring the flow of genes between locations.
Researchers at Leipzig University and the German Centre for Integrative Biodiversity Research (iDiv) have compiled the world's most comprehensive list of known plant species. It contains 1,315,562 names of vascular plants, thus extending the number by some 70,000 - equivalent to about 20%. The researchers have also succeeded in clarifying 181,000 hitherto unclear species names. The data set has now been published in Scientific Data. This marks the culmination of ten years of intensive research work.
