Researchers say there should be an international database containing the very latest information about organ donations and transplants, so policy makers can make informed decisions on whether to adopt an opt-out or opt-in system.

Cell division, the process that ensures equal transmission of genetic information to daughter cells, has been fundamentally conserved for over a billion years of evolution. Considering its ubiquity and essentiality, it is expected that proteins that carry out cell division would also be highly conserved. Challenging this assumption, scientists from Fred Hutchinson Cancer Research Center have found that one of the foundational proteins in cell division, previously shown to be essential in organisms as diverse as yeast, flies and humans, has been surprisingly lost on multiple occasions during insect evolution.

Eyeless Mexican cavefish show no metabolic circadian rhythm in either light and dark or constant dark conditions, according to a study published September 24, 2014 in the open-access journal PLOS ONE by Damian Moran from Lund University, Sweden, and colleagues.

Achieving complete breakdown of plant biomass for energy conversion in industrialized bioreactors remains a complex challenge, but new research shows that termite fungus farmers solved this problem more than 30 million years ago. The new insight reveals that the great success of termite farmers as plant decomposers is due to division of labor between a fungus breaking down complex plant components and gut bacteria contributing enzymes for final digestion.

Most organisms, including humans, have parasitic DNA fragments called "jumping genes" that insert themselves into DNA molecules, disrupting genetic instructions in the process. And that phenomenon can result in age-related diseases such as cancer. But researchers at the University of Rochester now report that the "jumping genes" in mice become active as the mice age when a multi-function protein stops keeping them in check in order to take on another role.

Although the immediate welfare consequences of removing infant chimpanzees from their mothers are well documented, little is known about the long-term impacts of this type of early life experience. In a year-long study, scientists from Lincoln Park Zoon observed 60 chimpanzees and concluded that those who were removed from their mothers early in life and raised by humans as pets or performers are likely to show behavioral and social deficiencies as adults.

Victoria Lundblad and Timothy Tucey are researchers at the Salk Institute.
Scientists at the Salk Institute have discovered an on-and-off "switch" in cells that may hold the key to healthy aging. This switch points to a way to encourage healthy cells to keep dividing and generating, for example, new lung or liver tissue, even in old age.

Rhinorex, a newly discovered dinosaur from the Late Cretaceous period, had an impressive nose.
Call it the Jimmy Durante of dinosaurs – a newly discovered hadrosaur with a truly distinctive nasal profile. The new dinosaur, named Rhinorex condrupus by paleontologists from North Carolina State University and Brigham Young University, lived in what is now Utah approximately 75 million years ago during the Late Cretaceous period.

New research published today in the online journal PLoS Outbreaks predicts new Ebola cases could reach 6,800 in West Africa by the end of the month if new control measures are not enacted.

Researchers in Biomedical Informatics at IMIM (Hospital del Mar Medical Research Institute) and at the Universitat Politècnica de Catalunya (UPC) have recently published a study in eLife showing that RNA called non-coding (IncRNA) plays an important role in the evolution of new proteins, some of which could have important cell functions yet to be discovered.

A team of Spanish researchers have obtained the first partial genome sequence of an ancient pig. Extracted from a sixteenth century pig found at the site of the Montsoriu Castle in Girona, the data obtained indicates that this ancient pig is closely related to today's Iberian pig. Researchers also discard the hypothesis that Asian pigs were crossed with modern Iberian pigs.

These are adult marine (top) and freshwater (bottom) threespine sticklebacks (Gasterosteus aculeatus) stained with a red dye that labels calcified bone.
Sticklebacks, the roaches of the fish world, are the ideal animal in which to study the genes that control body shape. They've moved from the ocean into tens of thousands of freshwater streams and lakes around the world, each time changing their skeleton to adapt to the new environment.

This image depicts gut microbiota.
Artificial sweeteners, promoted as aids to weight loss and diabetes prevention, could actually hasten the development of glucose intolerance and metabolic disease; and they do it in a surprising way: by changing the composition and function of the gut microbiota – the substantial population of bacteria residing in our intestines. These findings, the results of experiments in mice and humans, were published today in Nature. Among other things, says Dr. Eran Elinav of the Weizmann Institute's Immunology Department, who led this research together with Prof. Eran Segal of Computer Science and Applied Mathematics Department, the widespread use of artificial sweeteners in drinks and food may be contributing to the obesity and diabetes epidemic that is sweeping much of the world.
