Cornell develops technique for making living, functional cells glow

The development gives researchers insights into how hearts develop in living mouse embryos and could improve our understanding of irregular heartbeats, known as arrhythmias, as well as open doors to observing cellular processes to better understand basic physiology and disease.

Father-daughter inbreeding avoidance in a wild primate population

A 14 year behavioral and genetic study of a population of wild capuchin monkeys has shown that fathers almost never mate with their daughters, even though alpha males sire the majority of offspring produced by females unrelated to them.

Global evolutionary map reveals new insights into our last common ancestor

In 1870 the German scientist Ernst Haeckel mapped the evolutionary relationships of plants and animals in the first 'tree of life'.

Genome signature tagging used to quickly identify and distinguish between pathogens and harmless microbes

Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have developed a new, high-throughput technique for identifying the many species of microorganisms living in an unknown "microbial community."

Hydrogel scaffold materials used to create stable networks of blood vessels

Yale biomedical engineers have created an implantable system that can form and stabilize a functional network of fine blood vessels critical for supporting tissues in the body, according to a report in the Proceedings of the National Academy of Sciences.

Scientists can now predict memory of an event before it even happens

A team at UCL (University College London) can now tell how well memory will serve us before we have seen what we will remember.

Charles Darwin proven right on natural selection

The famous scientist would be pleased because a study published online this week provides the first clear evidence that natural selection, his favored mechanism of evolution, drives the process of species formation in a wide variety of plants and animals.

Low sugar, reduced calorie apples

The technology to produce low sugar fruits with up to half the calories of the natural variety has been developed by US scientists, writes Jennifer Rohn in Chemistry & Industry magazine.

New molecule could help in treating hospital infections

The scientists replaced a single atom from the molecular structure of vancomycin aglycon, a glycopeptide antibiotic that attacks the bacteria by inhibiting cell wall synthesis, significantly increasing the drug's spectrum of activity.

Using neural growth factor could allow researchers to mass produce stem cells for treatment of disease

Human embryonic stem cells (hES) offer great hope for the treatment of some devastating diseases, but finding a way to keep enough of these cells usable and healthy for transplantation in patients has been an ongoing problem.

Mystery of evolutionary growth in hominid brain size

Forget the textbook story about tool use and language sparking the dramatic evolutionary growth of the human brain. Instead, imagine ancient hominid children chasing frogs. Not for fun, but for food.

Ernst Mayr's theory illustrated in genetic epidemiology studies

The late, famed evolutionary biologist Ernst Mayr's theory of genetic revolution , introduced in 1954, remains controversial to this day and has many detractors.

Science is bypassing poor people

Applying science and technology to build a Pluto-bound spacecraft that travels more than 10 times faster -- 47,000 miles per hour -- than a speeding bullet is a great achievement. But can we apply technology to feed the 800 million hungry people in the world whose plight isn't improving in a modern world?
