Study questions life extension mechanism in roundworms

(Phys.org)—It's strange to think that there was a time when molecular cell biology was considered by professionals of other scientific specialties as disreputable or laughable. But the motivation for much cellular biology research around the mid-20th century was the search for the mechanisms of aging and the means to alter them—for centuries, people have been understandably frustrated by the indignities of aging and the burden of mortality, and the search for a "fountain of youth" was universally regarded as a foolish and hopeless endeavor.

Female burying beetle emits pheromone to ward off male desire during parental care

(Phys.org)—A team of researchers with members from several institutions in Germany has found that the female burying beetle gives off a pheromone during parental care that causes male beetles to temper their sexual advances.

University of Otago researchers studying chinook salmon have provided the first evidence that "cryptic female choice" (CFC) enhances fertilisation success and embryo survival.

Blurred lines: Human sex chromosome swapping occurs more often than previously thought

It turns out that the rigid "line in the sand" over which the human sex chromosomes—-the Y and X—- go to avoid crossing over is a bit blurrier than previously thought. Contrary to the current scientific consensus, Arizona State University assistant professor Melissa Wilson Sayres has led a research team that has shown that X and Y DNA swapping may occur much more often. And this promiscuous swapping, may in turn, aid in our understanding of human history and diversity, health and disease, as well as blur rigid chromosomal interpretations of sexual identity.

DNA molecules directly interact with each other based on sequence

Proteins play a large role in DNA regulation, but a new study finds that DNA molecules directly interact with one another in a way that's dependent on the sequence of the DNA and epigenetic factors. This could have implications for how DNA is organized in the cell and even how genes are regulated in different cell types, the researchers say.

Prairie dogs found to kill competing squirrels

(Phys.org)—A pair of researchers, one with the University of Maryland, the other the University of Tulsa, has found that white-tailed prairie dogs living on the North American prairie, sometimes kill ground squirrels that live in the same area.

Poor outlook for ash trees

The future for ash – the tree that gave us food, fuel and the Sweet Track, one of the oldest roads in the world – looks bleak, according to a new survey of its biology and ecology. The review by tree expert Dr Peter Thomas is the largest-ever survey of this much-loved tree and is published today in the Journal of Ecology.

Reconstructing the cell surface in a test tube

Like the phenomena of flocking birds and shoaling fish, the dance of molecules across a cell's surface has long fascinated theorists, physicists and biologists alike. Unlike bird and fish behaviour, however, cell surface dynamics cannot be observed and studied easily. However, it is important to understand these processes as they are crucial for cells to gain information about their environment and respond. So how does one understand the rules that govern movement of molecules across this arena? By reconstructing the cell surface from scratch, perhaps? Now, scientists from the National Centre for Biological Sciences (NCBS) in Bangalore have managed to do exactly that - construct a simplified cell surface from its constituent parts, namely, a mixture of fats and proteins. This reconstruction creates a crucial new tool that researchers can use to test theories on cell surface dynamics.
