A new way to prioritize species for conservation efforts outperforms other similar methods, according to research presented in PLOS ONE by Rikki Gumbs of Imperial College London, UK, and colleagues at the Zoological Society of London, UK.
The ongoing "sixth mass extinction," driven by human activity, threatens species around the world. A variety of different metrics...
Researchers at the University of Michigan Life Sciences Institute and the Howard Hughes Medical Institute have determined how satellite DNA, considered to be "junk DNA," plays a crucial role in holding the genome together.
Their findings, published recently in the journal eLife, indicate that this genetic "junk" performs the vital function of ensuring that chromosomes bundle...
A genetically engineered ferret could help reveal how humans got their big brains.
By inactivating a gene linked to abnormally small brain size in humans, researchers have created the first ferret with a neurological mutation. Although the original impetus of the work was to study human brain disease and development, says Howard Hughes Medical Institute (HHMI)...
The lengths that some males go to attract a mate can pay off in the short-term. But according to a new study from scientists at the Smithsonian's National Museum of Natural History (NMNH), extravagant investments in reproduction also have their costs.
By analyzing the fossils of thousands of ancient crustaceans, a team of scientists led by...
For more than 40 years, frog populations around the world have been declining. Now, a new study reports that some Central American frog species are recovering, perhaps because they have better defenses against a deadly fungal pathogen.
"It's a hopeful, optimistic chapter," said Louise Rollins-Smith, PhD, associate professor of Pathology, Microbiology and Immunology, and a co-author...
An Oxford University collaboration has shed light on the origins of some of South East Asia's most iconic and unique wildlife; the 'deer-pig' (Sulawesi Babirusa), 'warty pig' and the 'miniature buffalo.' In doing so, the research has revealed that Sulawesi, the island paradise where they were discovered, is younger than previously thought.
Sitting in a region...
