Zombie gene protects against cancer — in elephants

An estimated 17 percent of humans worldwide die from cancer, but less than five percent of captive elephants -- who also live for about 70 years, and have about 100 times as many potentially cancerous cells as humans -- die from the disease.

Three years ago, research teams from the University of Chicago and the University...

Snake fungal disease alters skin microbiome in eastern Massasaugas

In the first study of its kind, researchers characterized the skin microbiome of a population of free-ranging snakes to begin to understand how the animals' environmental microbial community may promote disease resistance as well as how it may be disrupted by infection.

The study, which was recently published in Scientific Reports, a Nature research journal, focused...

How MERS Coronavirus evolves to infect different species

In the past 15 years, two outbreaks of severe respiratory disease were caused by coronaviruses transmitted from animals to humans. In 2003, SARS-CoV (severe acute respiratory syndrome coronavirus) spread from civets to infect more than 8,000 people, leading to a year-long global public health emergency. MERS-CoV (Middle East respiratory syndrome coronavirus), first identified in 2012,...

Fishing quotas upended by nuclear DNA analysis

For decades, mitochondrial DNA analysis has been the dominant method used to make decisions about fishing quotas, culling, hunting quotas, or translocating animals from one population of a threatened species to another.

A study published in Scientific Reports shows that, while mitochondrial DNA analysis is very useful for a number of applications, analysing genetic differences for...

Illinois' imperiled eastern massasauga rattlesnakes retain genetic diversity

Habitat loss, habitat fragmentation and the loss of genetic diversity are the three main factors driving the extinction of many wild species, and the few eastern massasauga rattlesnakes remaining in Illinois have certainly suffered two of the three. A long-term study of these snakes reveals, however, that -- despite their alarming decline in numbers --...

When it comes to regrowing tails, neural stem cells are the key

Cut off a salamander's tail and, in a few weeks, a near-perfect replacement grows. Do the same to a lizard and a new tail will regrow, but it won't be the same as the original. By comparing tail regeneration between the two animals, researchers at the University of Pittsburgh School of Medicine found that stem...
