A new approach to estimating tumor growth based on breast screening results from almost 400,000 women is published today in Breast Cancer Research. This new model can also estimate the proportion of breast cancers which are detected at screening (screen test sensitivity). It provides a new approach to simultaneously estimating the growth rate of breast cancer and the ability of mammography screening to detect tumors.

The results of the study show that tumor growth rates vary considerably among patients, with generally slower growth rates with increasing age at diagnosis. Understanding how tumours grow is important in the planning and evaluation of screening programs, clinical trials, and epidemiological studies. However, studies of tumour growth rates in people have so far been based mainly on small and selected samples.

The first genome sequencing project of a mammal that lays eggs is complete and, like the animal itself, the DNA of the platypus is something of a patchwork.

The platypus, found in eastern Australia, including Tasmania, is one of the five species of mammals that lay eggs instead of giving birth to live young. The four species of echidna are the other mamimals that share this distinction.

The curious discovery of the duck-billed, egg-laying, otter-footed, beaver-tailed, venomous platypus in 1798, comfortable on land and in water, convinced British scientists that it must be a hoax. Sketches of its appearance were thought to be impossible.

But new research proves that the oddness of the platypus' looks isn't just skin-deep. Platypus DNA is an equally cobbled-together array of avian, reptilian and mammalian lineages that may hold clues for human disease prevention.

Rensselaer Polytechnic Institute graduating senior Jeffery Martin has put his basic knowledge of sugars to exceptional use by creating a lab-on-a-chip device that builds complex, highly specialized sugar molecules, mimicking one of the most important cellular structures in the human body - the Golgi Apparatus.

Among the most important and complex molecules in the human body, sugars control not just metabolism but also how cells communicate with one another.

Cells build sugars in a cellular organelle known as the Golgi Apparatus. Under a microscope, the Golgi looks similar to a stack of pancakes. The strange-looking organelle finishes the process of protein synthesis by decorating the proteins with highly specialized arrangements of sugars. The final sugar-coated molecule is then sent out into the cell to aid in cell communication and to help determine the cell’s function in the body.
