Does Promiscuity Prevent Extinction?

February 26, 2010 Health News No Comments

Promiscuous females may be the key to a species’ survival, according to new research by the Universities of Exeter and Liverpool. Published 25 February in Current Biology, the study could solve the mystery of why females of most species have multiple mates, despite this being more risky for the individual. Known as ‘polyandry’ among scientists, the phenomenon of females having multiple mates is shared across most animal species, from insects to mammals. This study suggests that polyandry reduces the risk of populations becoming extinct because of all-female broods being born…

Can Drug & Device Makers Innovate Themselves to Extinction?

November 25, 2009 Health News No Comments

A study of heart-attack patients published in the late 1980s was wildly successful. Researchers showed they could lower the heart-attack death rate to 8% from 13% by giving patients aspirin and a drug called streptokinase. These days, though, an 8% mortality rate would be disastrous; the rate in most studies of heart attack patients is somewhere around 4%.
That points to a challenge for companies developing new therapies for heart disease (and other well treated maladies): The better existing therapies are, the harder it is to come up with something that’s an improvement. An essay published in this week’s JAMA calls… Continue reading

The role of mammalian ribonucleases (RNases) in cancer.

March 20, 2010

Authors: Kim WC, Lee CH
Ribonucleases (RNases) are a group of enzymes that cleave RNAs at phosphodiester bonds resulting in remarkably diverse biological consequences. This review focuses on mammalian RNases that are capable of, or potentially capable of, cleaving messenger RNA (mRNA) as well as other RNAs in cells and play roles in the development of human cancers. The aims of this review are to provide an overview of the roles of currently known mammalian RNases, and the evidence that associate them as regulators of tumor development. The roles of these RNases as oncoproteins and/or tumor suppressors in influencing cell… Continue reading
