The decline of modern day fertility

Researchers at the University of Sheffield have shown that mothers are choosing to have fewer children in order to give their children the best start in life, but by doing so are going against millenia of human evolution.

Adaptive functional evolution of leptin in cold-adaptive pika family

Researchers at the Northwest Institute of Plateau Biology, Chinese Academy of Sciences have put forward the viewpoint for the first time that adaptive functional evolution may occur in the leptin protein of the pika (Ochotona) family, a typical cold-adaptive mammal.

Genetic switches could lower cost of producing drugs, proteins

Bacteria have evolved complex mechanisms called quorum sensing systems that provide for cell-to-cell communication, an adaptation that allows them to wait until their population grows large enough before mounting an attack on a host or competing for nutrients.

Computer model for osteoporosis diagnostics

Osteoporosis, a common age-related disease, is being investigated by a group of biomechanical engineers at Vienna University of Technology (TU Vienna).

Studies highlight MRSA evolution and resilience

Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) infections are caused primarily by a single strain USA300 of an evolving bacterium that has spread with "extraordinary transmissibility" throughout the United States during the past five years, according to a new study led by National Institutes of Health (NIH) scientists.

Molecular evolution of limb length

In the January 15th issue of G&D, a research team led by Dr. Richard Behringer at MD Anderson Cancer Center reports that they have successfully switched the mouse Prx1 gene regulatory element with the Prx1 gene regulatory region from a bat - and although these two species are separated by millions of years of evolution - the resulting transgenic mice displayed abnormally long forelimbs.

Why we sleep - roundworm C. elegans unlocks sleep mysteries

The roundworm C. elegans, a staple of laboratory research, may be key in unlocking one of the central biological mysteries: why we sleep.

Dissecting the genetic components of adaptation of E. coli to the mouse gut

New insights into the evolutionary mechanisms that facilitate the remarkably fast adaptation of intestinal bacteria within their natural environment are provided in the January issue of PLoS Genetics by researchers from INSERM and INRA at University Paris Descartes.

Genetic evolution of tumours according to their growth dynamics.

A study co-directed by the Universidad Complutense de Madrid and La Paz hospital in Madrid identifies a protein of high expression in cells located at the tumour boundary that could play an essential role in the evolution of tumours and their invasive potential.

New sugary insights into H5N1 avian flu virus

Scientists have identified a key factor that determines the ability of influenza viruses to infect cells of the human upper respiratory tract - a necessary step for sustaining spread between people.

New understanding of cell's inner workings

A group of scientists in Princeton's Department of Ecology and Evolutionary Biology has uncovered a new biological mechanism that could provide a clearer window into a cell's inner workings.

MIT researchers discover key to bird flu in humans

MIT researchers have uncovered a critical difference between flu viruses that infect birds and humans, a discovery that could help scientists monitor the evolution of avian flu strains and aid in the development of vaccines against a deadly flu pandemic.

Study shows how climate change will increase human mortality

A Stanford scientist has spelled out for the first time the direct links between increased levels of carbon dioxide in the atmosphere and increases in human mortality, using a state-of-the-art computer model of the atmosphere that incorporates scores of physical and chemical environmental processes.

Avalon Explosion shaped early history of multicellular life

Scientists have known for some time that most major groups of complex animals appeared in the fossils record during the Cambrian Explosion, a seemingly rapid evolutionary event that occurred 542 million years ago.
