“pipe,” preventing blood fl ow. Eventually, the blood-starved tissue dies. If that happens in the heart or the brain, a heart attack or stroke occurs. Few believe that tidy explanation anymore. Twenty years of research show that arteries bear little resemblance to pipes. They contain living cells that communicate with one another and their environment. They also participate in the development of the fatty deposits that grow within vessel walls— few which actually shrink vessels to a pinpoint… 

Special News Report: Putting Prions to the Test

While no protein has yet been proven to cause scrapie, a number of researchers say they are close to showing that one does, and similar aberrant proteins, they say, may cause mad cow disease, or bovine spongiform encephalopathy, which panicked Britain this spring.

Mechanical behavior of “living quicksand”: Simulation and Experiment

The nature and danger of quicksand has been disputed since a long time. Despite widespread belief that humans can be swallowed or even sucked in, engineers of soil mechanics have typically asserted

Life, Love and Death: Models of Biological Reproduction and Aging

The half-century old mutation-accumulation hypothesis is talked about, which is somewhat similar to thermal physics with its balance between order (energy minimization) and disorder (entropy).

Defense Technical Information Center Compilation Part Notice ADP 019699

It is shown that tuning the reactivity of the surfaces of two obstacles defining a gap can control the passage of cells through the gap, and infer the importance of a proper treatment of boundary conditions in any future pore-level quantitatve modeling of mass transport and cellular response in porous media.

The Architecture of Life A universal set of building rules seems to guide the design of organic structures — from simple carbon compounds to complex cells and tissues

Self-assembly, the phenomenon, in which components join together to form larger, stable structures having new properties that could not have been predicted from the characteristics of their individual parts, is observed at many scales in nature.

Keilin's respiratory chain concept and its chemiosmotic consequences.

It was obviously my hope that the chemiosmotic rationale of vectorial metabolism and biological energy transfer might one day come to be generally accepted, and I have done my best to argue in favour

Risk reduction and pharmacological strategies to prevent progression of aortic aneurysms

There exists a striking gap in the literature when it comes to pharmacologic management of non-Marfan Syndrome patients with thoracic aortic aneurysm patients with Marfan Syndrome, and this is an important future direction for aorticsm research.


Astronomers know since the 1930s that the universe contains more than what meets the eye. Galaxies within clusters of galaxies and stars within galaxies are moving around faster than the gravity of

LPS‐binding proteins and receptors

Various phenotypes of mice that lack genes encoding CD14, the scavenger receptor, and LBP are summarized to provide a means to develop and evaluate novel therapeutic approaches to the control of endotoxin shock.

The Origin of Life : A Critique of Current Scientific Models

The evidence for the nature of the primitive atmosphere is examined and the possibility of ribonucleic acid (RNA) as the first selfreplicating molecule is evaluated, and the focus is then on DNA, proteins and the first cells.
