Mountain-dwelling East African honey bees have distinct genetic variations compared to their savannah relatives that likely help them to survive at high altitudes, report researchers.
Combinations of three antibiotics — that are each ineffective against superbugs when used alone — are capable of eradicating two of the six ESKAPE pathogens when delivered together, scientists have discovered.
The snowy-feathered head and distinctive brown body of the bald eagle is a proud national symbol of the United States, adorning the country’s currency and passports. The lion, known as ‘King of the Beasts,’ represents national strength and identity in several African countries. But, how are populations of the planet’s most valued wildlife faring in the 21st century? How well are societies protecting the species they have chosen to embody their ideals and represent their national identity?
Ecologists have observed an unusual way in which treetop-grazing goats may be benefiting the trees: the goats spit out the trees’ seeds.
Evolution is a difficult concept for many students at all levels, however, a study has demonstrated a simple cost-free way to significantly improve students’ understanding of evolution at the secondary level: teach genetics before you teach them evolution.
Scientists are transforming how complex marine data from the Ocean Health Index is synthesized, communicated and used for coastal management.
Scientists have discovered a dietary strategy that may address obesity by reducing endotoxemia, a major contributor to chronic, low-grade inflammation (CLGI). The researchers uncovered an interaction between dietary capsaicin (CAP), the major pungent component in red chili, and gut microbiota. This novel mechanism for the anti-obesity effect of CAP acts through prevention of microbial dysbiosis.
Researchers have modified an experimental malaria vaccine and showed that it completely protected four of eight monkeys that received it against challenge with the virulent Plasmodium falciparum malaria parasite. In three of the remaining four monkeys, the vaccine delayed when parasites first appeared in the blood by more than 25 days.
A new process triples the fraction of biomass converted to high-value products to nearly 80 percent, also tripling the expected rate of return for an investment in the technology from roughly 10 percent (for one end product) to 30 percent.
Insects possess a naturally occurring resistance to the use of gene-editing technology to prevent diseases such as malaria, new research shows.
