Stronger turbine blades with molybdenum silicides

Molybdenum silicides can improve the efficiency of turbine blades in ultrahigh-temperature combustion systems, researchers have discovered.

Oxygen levels were key to early animal evolution, strongest evidence now shows

It has long puzzled scientists why, after 3 billion years of nothing more complex than algae, complex animals suddenly started to appear on Earth. Now, a team of researchers has put forward some of the strongest evidence yet to support the hypothesis that high levels of oxygen in the oceans were crucial for the emergence of skeletal animals 550 million years ago.

To produce biopharmaceuticals on demand, just add water

Researchers have created tiny freeze-dried pellets that include all of the molecular machinery needed to translate DNA into proteins, which could form the basis for on-demand production of drugs and vaccines.

Landmark map reveals the genetic wiring of cellular life

A new map breaks away from the old way of studying genes one at a time, showing how genes interact in groups to shed light on the genetic roots of diseases.

Apple, lettuce can remedy garlic breath

Garlic -- consumers either love or hate the taste, but one thing is for certain, no one likes it when the scent of it sticks around on their breath. Now, garlic lovers may have a new solution to their halitosis problem. A study has found that eating raw apple or lettuce may help reduce garlic breath.

Caspian terns discovered nesting 1,000 miles farther to the north than ever recorded in...

In the late summer of 2016, a field team monitored Caspian tern chicks through to fledging in Cape Krusenstern National Monument in Alaska. This discovery of Caspian terns breeding above the Arctic Circle in the Chukchi Sea is nearly 1,000 miles farther north than previously recorded – a strikingly large jump in the range of nesting for this (or any) species.

Underwater ‘Cystoseira zosteroides’ forests, the Mediterranean algae, threatened by human activity impact

The effects of an intense storm every twenty-five years could make the marine alga populations of Cystoseira zosteroides disappear – an endemic species of the Mediterranean with great ecological value for the biodiversity of marine benthos – according to a new article.

Lipid receptor fosters infection of the uterus in bitches

In the female dog, cells of the uterus can accumulate lipid droplets to form so-called foamy epithelial cells during late metoestrus. These cells produce a hormone that is involved in the implantation of the embryo in the uterus. A team of researchers has now shown for the first time that the factor assisting the cells in lipid accumulation also facilitates the binding of bacteria to the epithelial cells, resulting in serious infections of the uterus in female dogs.

Al­tern­at­ive ox­i­dase from a mar­ine an­imal works in mam­mals, com­bats bac­terial sepsis

Mitochondrial alternative oxidase from a sea-squirt works as a safety valve for stressed mitochondria. This property enables it to stop the runaway inflammatory process that leads to multiple organ failure and eventual death in bacterial sepsis.

Long-term monitoring of sapovirus infection in wild carnivores in the Serengeti

Sapoviruses are an emerging group of viruses of the group of caliciviruses and well known agents of gastric enteritis, but very little is currently known about their role in wildlife ecology or the genetic strains that infect wildlife. Research findings by a group of scientists describe for the first time, sapovirus infection in African wild carnivores in the Serengeti ecosystem, including the spotted hyena, the African lion and the bat-eared fox. The results from two decades of monitoring revealed several sapovirus outbreaks of infection in spotted hyenas and, counter-intuitively, that the risk of infection declined as group sizes increased.
