Chemical engineers Associate Professor Raymond Dagastine and Dr Rico Tabor shed light on the phenomena of bubbles and droplets, and explain why their underlying physics and chemistry are important to a wide range of industrial processes. With science host Dr Shane Huntington.
1.2.1 Cell–cell contact-dependent signalling
In some instances, cells may communicate directly with their immediate neighbour through gap junctions (Figure 3a). Communication via gap junctions partially bypasses the signalling model we have outlined above in Figure 2. Gap junctions connect the cytoplasm of neighbouring cells via protein channels, which allow the passage of ions and small molecules (s

About the book:
"This unforgettable book is the first-person account of a miracle—indeed, a whole series of miracles. One of the uprooted youngsters known as the Lost Boys of Sudan, John Bul Dau was 12 years old when civil war ravaged his village and shattered its age-old society, a life of herding and agriculture marked by dignity, res

The Role of International Negotiations in Addressing the Climate Challenge
With frightening evidence for climate change mounting around the globe, from droughts and massive forest fires to melting glaciers and rising sea levels, you might think nations would wish to work together to meet such a grave threat. Instead, as U.S. climate negotiator

Planet of the Taxpayers
"It is true that a form of slavery exists and thrives today, all over the world. We do live in cages."
The remake of The Planet of the Apes — the apes look real this time — purports to give the backstory of how it is that the world came to be governed by primates while the handf

Ronald DePinho, M.D., on his presidential plans
On Thursday, Sept. 1, 2011, Ronald DePinho, M.D., began his presidency of MD Anderson Cancer Center. Here he shares his plans for his tenure as president. DePinho is internationally recognized for basic and translational research in cancer, aging and age-associated degenerative disorders. He's the fourth full-time president of MD Anderson.
DePinho succeeds John Mendelsohn, M.D., who remains on MD Anderson faculty, returning to clinical and translational research as co-director of a new Institut
Prediction of Chemical and Biological Properties of Organic Compounds from Molecular Structure
This website is a PDF file of 32 slides and accompanying notes that describe the process of determining quantitative structure activity relationships. The slides focus on the ADAPT software, but are generally useful to anyone interested in QSAR, and discuss the details of Structure Entry and Molecular Modeling, Descriptor Generation, Feature Selection, Model construction, and Model Validation.
Principal Components Analysis Tutorial
This site provides a clear introduction to the principle component analysis (PCA) without overwhelming the student. The tutorial includes a brief introduction and an explanation of the mathematics of PCA.
