The fittest males don't always get the girl, biologists report. Study tackles a paradox in species from fruit flies to humans: If warriors win the spoils, why don't males evolve towards super-aggressiveness? Female fruit flies sometimes choose males who win fights, sometimes choose males who do not fight, and sometimes choose males for no obvious reason, say biologists.
Anti-cancer Medicines Obtained From The Elecampe, A Wild Plant Growing In The Mediterranean, Researchers Say

Scientists have found out that the plant “Dittirichia viscose”, known as elecampe, can be used to obtain inhibitors of neurogenic vasodilatation, a significant progress in migraine and cancer treatments.
How Dietary Restriction Slows Down Aging

Scientists have uncovered details about the mechanisms through which dietary restriction slows the aging process. Working in yeast cells, they have linked ribosomes, the protein-making factories in living cells, and Gcn4, a specialized protein that aids in the expression of genetic information, to the pathways related to dietary response and aging.

Multiple lethal pathogens such as H5N1 avian flu trigger acute lung injury with a high death rate. Scares of an epidemic have led to an increasing interest in understanding the molecular mechanisms that lead to this condition. Scientists have now identified oxidative stress and innate immunity as a common pathway that controls the severity of ARDS.
Charting The Epigenome: Zooming In On Genome-wide DNA At Single Base Resolution

Until recently, the chemical marks littering the DNA inside our cells like trees dotting a landscape could only be studied one gene at a time. But new high-throughput DNA sequencing technology has enabled researchers to map the precise position of these individual DNA modifications throughout the genome of the plant Arabidopsis thaliana, and chart its effect on the activity of any of Arabidopsis' roughly 26,000 genes.

All time is all time. It does not change. It does not lend itself to warnings or explanations. It simply is. Take it moment by moment, and you will find that we are all, as I've said before, bugs in amber.
Archaeology is not only the hand maid of history, it is also the conservator of art.
Yesterday I was a dog. Today I'm a dog. Tomorrow I'll probably still be a dog. Sigh! There's so little hope for advancement.
