Nematode proteins shed light on infertility      (via sciencedaily.com)     Original source 

Biologists developed a method for illuminating the intricate interactions of the synaptonemal complex in the nematode C. elegans. The authors identified a trio of protein segments that guide chromosomal interactions, and pinpointed the location where they interact with each other. Their novel method uses a technique known as genetic suppressor screening, which can serve as a blueprint for research on large cellular assemblies that resist traditional structural analysis.

Bacteria load their syringes      (via sciencedaily.com)     Original source 

Many bacterial pathogens use small injection apparatuses to manipulate the cells of their hosts, such as humans, so that they can spread throughout the body. To do this, they need to fill their syringes with the relevant injection agent. A technique that tracks the individual movement of proteins revealed how bacteria accomplish this challenging task.

New material allows for better hydrogen-based batteries and fuel cells      (via sciencedaily.com)     Original source 

Researchers have developed a solid electrolyte for transporting hydride ions at room temperature. This breakthrough means that the full advantages of hydrogen-based solid-state batteries and fuel cells can be had without the need for constant hydration. This will reduce their complexity and cost, which is essential for advancing towards a practical hydrogen-based energy economy.

Big impacts from small changes in cell      (via sciencedaily.com)     Original source 

Tiny things matter -- for instance, one amino acid can completely alter the architecture of the cell. Researchers have now investigated the structure and mechanics of the main component of the cytoskeleton of the cell: a protein known as actin. Actin is found in all living cells where it has a range of important functions -- from muscle contraction to cell signalling and cell shape. This protein comes in two different varieties termed 'isoforms', which are known as gamma actin and beta actin.

How jellyfish regenerate functional tentacles in days      (via sciencedaily.com)     Original source 

At about the size of a pinkie nail, the jellyfish species Cladonema can regenerate an amputated tentacle in two to three days -- but how? Regenerating functional tissue across species, including salamanders and insects, relies on the ability to form a blastema, a clump of undifferentiated cells that can repair damage and grow into the missing appendage. Jellyfish, along with other cnidarians such as corals and sea anemones, exhibit high regeneration abilities, but how they form the critical blastema has remained a mystery until now.

The future of canine stem cell therapy: unprecedented, painless, and feeder-free      (via sciencedaily.com)     Original source 

Scientists have developed an efficient, non-invasive, and pain-free method to generate canine-induced pluripotent stem cells (iPSCs). They identified six reprogramming genes that can boost canine iPSC generation by 120 times compared to conventional methods using fibroblasts. The iPSCs were created from urine-derived cells without the need for feeder cells, an impossible feat until now. Their findings are expected to advance regenerative medicine and genetic disease research in veterinary medicine.

The key mechanism to cell growth has been elucidated      (via sciencedaily.com)     Original source 

Researchers have discovered how amino acids activate a key cell, TORC1, which is a master regulator in living organisms that controls whether cells grow or recycle their contents in yeast. Notably, the team found that the amino acid cysteine is sensed by a protein called Pib2 and that the two bind together to trigger TORC1. This is important because faulty TORC1 has been linked to disease such as cancer.

Bugs that help bugs: How environmental microbes boost fruit fly reproduction      (via sciencedaily.com)     Original source 

A research group found that in female fruit flies, microorganisms enhance reproductive function, boosting the number of cells that form eggs and the number of mature eggs. This is done by controlling the release of hormones to speed up cell division in the ovaries, and limiting programmed cell death. These findings could improve reproductive medicine and could aid the development of new methods to enhance fertility.
