Cyanobacteria belong to the Earth's oldest organisms. They are still present today in oceans and waters and even in hot springs. By producing oxygen and evolving into multicellular forms, they played a key role in the emergence of organisms that breathe oxygen.

A team of scientists under the supervision and instruction of evolutionary biologists from the University of Zurich wrote a paper showing that cyanobacteria developed multicellularity around one billion years earlier than eukaryotes (cells with one true nucleus) and at almost the same time as multicellular cyanobacteria appeared, a process of oxygenation began in the oceans and in the Earth's atmosphere.  

A new view of 20,000-year old supernova remnant W50 provides more clues to the history of this giant cloud that resembles a beloved endangered species, the Florida Manatee. W50 is nearly 700 light years across,  so it covers two degrees on the sky - the span of four full Moons

Studies by Ding et al (Cell 2012) revealed that telomerase dysfunction early in disease onset creates genomic aberrations crucial for telomerase-driven prostate cancer metastasis into the lumbar spine.

Live imaging technology is becoming an increasing popular tool to visualize real-time cellular events in the tumor microenvironment during metastatic progression.

McCormick Place- Chicago, IL, March 31st- April 4th 2012- was flocked with scientists across the world for the Annual American Association for Cancer Research (AACR) meeting. As with each year, the meeting featured endless plenary presentations, symposiums, as well as poster sessions and exhibitions that covered exciting advancements and technologies in the global effort to end cancer.

The UK government needs to monitor surrogate pregnancy more carefully, says Eric Blyth, professor of social work at the University of Huddersfield. Couples seeking to build a family, and surrogate mothers overseas who help them, are in danger of emotional, physical and financial exploitation.

Wolves and dogs are genetically very similar, so why did dogs become "man's best friend" while wolves remain wild?

Kathryn Lord at the University of Massachusetts Amherst suggests the different behaviors are related to the animals' earliest sensory experiences and the critical period of socialization.  Not much is known about sensory development in wolf pups and assumptions are usually extrapolated from what is known for dogs - but there are significant differences in early development between wolf and dog pups, chief among them timing of the ability to walk.
