Discovery: Plants use 'Trojan horse' to fight mold invasions      (via sciencedaily.com)     Original source 

Scientists have discovered that plants send tiny, innocuous-seeming lipid 'bubbles' filled with RNA across enemy lines, into the cells of the aggressive mold. Once inside, different types of RNA come out to suppress the infectious cells that sucked them in.

Cells of the future: A key to reprogramming cell identities      (via sciencedaily.com)     Original source 

The intricate process of duplicating genetic information, referred to as DNA replication, lies at the heart of the transmission of life from one cell to another and from one organism to the next. This happens by not just simply copying the genetic information; a well-orchestrated sequence of molecular events has to happen at the right time. Scientists have recently uncovered a fascinating aspect of this process known as 'replication timing' (RT) and how special this is when life commences.

The evolutionary timeline of diminished boric acid and urea transportation in aquaporin 10      (via sciencedaily.com)     Original source 

Aquaporin (Aqp) 10 water channels in humans allow the free passage of water, glycerol, urea, and boric acid across cells. However, Aqp10.2b in pufferfishes allows only the passage of water and glycerol and not urea and boric acid. Researchers sought to understand the evolutionary timeline that resulted in the variable substrate selection mechanisms among Aqp10s. Their results indicate that Aqp10.2 in ray-finned fishes may have reduced or lost urea and boric acid permeabilities through evolution.

New study examines the relationship between the rate of wound healing, the circadian rhythm, and 'hair' on cells      (via sciencedaily.com)     Original source 

Nearly every organism on Earth follows a natural circadian rhythm that is coded by your cell's clock genes, which do exactly as you suspect from the name: regulate your body's rhythm on a 24-hour basis. Most cells in mammalian bodies have cilia of some sort, which are hair-like structures that perform a variety of functions such as movement for motile cilia and aiding in structure in function for non-motile, or primary, cilia. The primary cilia also act as a sensory organ for the cell, a function which has illuminated the primary cilia's potential role in the healing process and how bodies heal at a different rate according to our circadian rhythm. In this research, the role of the primary cilia, biological clock and wound healing is explored.
