How immune cells communicate to fight viruses      (via sciencedaily.com)     Original source 

Chemokines are signalling proteins that orchestrate the interaction of immune cells against pathogens and tumors. To understand this complex network, various techniques have been developed to identify chemokine-producing cells. However, it has not yet been possible to determine which cells react to these chemokines. Researchers have now developed a new class of genetically modified mice that enables the simultaneous identification of chemokine producers and sensors.

Cells may possess hidden communication system      (via sciencedaily.com)     Original source 

Cells constantly navigate a dynamic environment, facing ever-changing conditions and challenges. But how do cells swiftly adapt to these environmental fluctuations? A new study is answering that question by challenging our understanding of how cells function. A team of researchers suggests that cells possess a previously unknown information processing system that allows them to make rapid decisions independent of their genes.

Color variants in cuckoos: The advantages of rareness      (via sciencedaily.com)     Original source 

Every cuckoo is an adopted child -- raised by foster parents, into whose nest the cuckoo mother smuggled her egg. The cuckoo mother is aided in this subterfuge by her resemblance to a bird of prey. There are two variants of female cuckoos: a gray morph that looks like a sparrowhawk, and a rufous morph. Male cuckoos are always gray.

Unveiling the mysteries of cell division in embryos with timelapse photography      (via sciencedaily.com)     Original source 

The beginning of life is shrouded in mystery. While the intricate dynamics of mitosis is well-studied in the so-called somatic cells -- the cells that have a specialized function, like skin and muscle cells -- they remain elusive in the first cells of our bodies, the embryonic cells. Embryonic mitosis is notoriously difficult to study in vertebrates, as live functional analyses and -imaging of experimental embryos are technically limited, which makes it hard to track cells during embryogenesis.

Lead-vacancy centers in diamond as building blocks for large-scale quantum networks      (via sciencedaily.com)     Original source 

A lead-vacancy (PbV) center in diamond has been developed as a quantum emitter for large-scale quantum networks by researchers. This innovative color center exhibits a sharp zero-phonon-line and emits photons with specific frequencies. The PbV color center stands out among other diamond color centers due to its ability to maintain optical properties at relatively high temperatures of 16 K. This makes it well-suited for transferring quantum information in large-scale quantum networks.
