Testicular macrophages are guardians of fertility

The origin, development, and characteristics of two types of testicular macrophage have been described. To elucidate the nature of these immune cells, the researchers used a novel cell tracing method. Their findings are of fundamental importance. They may help understand certain kinds of infertility in men and find new treatments for them.

Novel software can recognize eye contact in everyday situations

Human eye contact is an important information source. Nonetheless, so far, possibilities to recognize eye contact in everyday situations have been very limited. Computer scientists have now developed a method by the aid of which it is possible to detect eye contact, independent of the type and size of the target object, the position of the camera, or the environment.

Jackdaws flap their wings to save energy

For the first time, researchers have observed that birds that fly actively and flap their wings save energy. Biologists have now shown that jackdaws minimize their energy consumption when they lift off and fly, because the feathers on their wing tips create several small vortices instead of a single large one. The discovery could potentially be applied within the aeronautical industry.

New malaria analysis method reveals disease severity in minutes

Investigators have found that measuring changes in red blood cell deformability is a robust, sensitive method for inferring heme-induced oxidative stress. Using a simple device that measures RBC deformability, malaria progression may be assessed in a matter of minutes.

Material-independent nanocoating antimicrobial spray extends the shelf life of produce

Scientists have developed a sprayable nanocoating technique using plant-derived polyphenol that can be applied to any surface. This new nanocoating process can be completed in seconds to form nanometer-thick films, allowing for the coating of commodity goods, such as shoe insoles and fruits, in a controlled fashion.
