Darcin in Mice Urine Attracts Other Mice

Darcin in Mice Urine Attracts Other Mice Repeatedly

Mice seem to be addicted to the scent of urine and repeatedly go back to spots where they found the excretions. Researchers have discovered that this behavior is triggered by a single protein in the urine of male mice.

Lab-Made Mouse Oocytes Produce Fertile and Viable Offspring


Japanese scientists have been able to coax mouse stem cells into becoming viable eggs that were able to produce healthy offspring. This will provide a powerful tool to study the basic elements of mammalian development and infertility.

Early Intake of Antibiotics Linked to Obesity in Mice


Bacteria living within the gut could have a link to obesity, possibly explaining how antibiotics fatten farm animals, and humans as well, and predispose some organisms to obesity.

Scientists Discover New Type of Extra-Chromosomal DNA

Profile of eccDNA throughout the life cycle of Drosophila. 2D-gel blots of DNA samples from different stages of the Drosophila life cycle were hybridized with a total genomic DNA probe (A—F) or a 5S rDNA probe (G—J). The panels represent 2D-gel blots of (A,I) pre-MBT embryos, (B,H) late embryos, (C,I) first-instar larvae, (D,J) third-instar larvae, (E) young adult flies (1 day old), and (F) old adult flies (33 days old). The hybridization patterns reveal a decrease in the relative amount of eccDNA during embryogenesis (cf. panels A,B and panels G,H), and a gradual return to the initial levels in the larva and young adult stages. A slight decrease is observed in eccDNA levels in old adult flies compared with young adult flies. Image: genome.cshlp.org

Scientists from the University of Virginia and University of North Carolina have discovered a previously unidentified type of circular DNA molecule occurring outside the chromosomes in mouse and human cells. The findings were published in the journal Science.

Sirtuin Protein SIRT6 Linked to Longevity in Mammals


A member of the sirtuin family of proteins, SIRT6, has been shown to extend lifespans in mammals. Researchers studying the aging process have long been intrigued by the sirtuin genes and their associated proteins. Recent results published in the journal Nature suggest that the overexpression of this one gene can lengthen lifespan in male mice by up to 15.8%.

The Tale of Mice of a Different Tail

080511_rg_UnusualMice_01.jpgWhile there are a few touch-based input devices available for PCs and desktop computers, most users still rely on the tried and true mouse. Productivity and physical health can greatly depend upon having the right mouse in hand configured correctly. But sometimes you also want a mouse that just looks different…a whole lot of different.
