Mutations that allow bird flu strain to spread among humans identified

Scientists have identified several genetic mutations that, should they arise, could potentially allow the avian influenza strain H7N9 to spread between humans.

New genetic technique could help identify potential drug targets for malaria

Scientists have developed a new technique for investigating the effects of gene deletion at later stages in the life cycle of a parasite that causes malaria in rodents, according to a new study. The novel approach could enhance research into potential drug targets for malaria treatment.

Alternative hypothesis on the faunal colonization of the Himalayas?

Until now, the fauna of the Himalayas was considered to be an “immigration fauna," with species that have immigrated primarily from neighboring regions since the geological formation of this mountain range. Using molecular-genetic methods, a research team has now tested an alternative colonization hypothesis on lazy toads. The findings indicate that this group arose earlier than assumed in southern Tibet, and went on to colonize the Himalayas from there after its formation.

Taking circular economy to the next level

While principles of a circular economy have been adopted by businesses, governments and NGOs, leading researchers say it's time to take the discussion and analysis to the next level.

Distant fish relatives share looks

Scientists have found evidence that even distantly related Australian fish species have evolved to look and act like each other, which confirms a central tenet of evolutionary theory.

Antibiotic design strategy boosts odds against resistance development

A new rational drug design technique that uses a powerful computer algorithm to identify molecules that target different receptor sites on key cellular proteins could provide a new weapon in the battle against antibiotic resistance, potentially tipping the odds against the bugs.

Brazilian carnivorous mammal-like reptile fossil may be new Aleodon species

Some Late Triassic Brazilian fossils of mammal-like reptiles, previously identified as Chiniquodon, may in fact be the first Aleodon specimens found outside Africa.

Older and wiser: Female elk can learn to avoid hunters with age

As female elk get older, they adopt strategies for avoiding hunters in Canada, according to a new study.

Scientists discover new structures in bacteria, seek to determine function

Using high magnification imaging, a team of researchers has identified several never before seen structures in bacteria that represent molecular machinery.

Donor microbes persist two years after fecal transplant to treat C. difficile infection

Researchers have made the first direct demonstration that fecal donor microbes remained in recipients for months or years after a transplant to treat the diarrhea and colitis caused by recurrent Clostridium difficile infections -- a serious and stubborn cause of diarrhea after an antibiotic treatment for some other illness.
