Nano-particles effective in killing cancer with one-two punch of chemotherapeutics

... pores in the cancer cell's membranes and has been simulated with supercomputers by Michael F. Klein and Goundla Srinivas of Penn's Department of Chemistry. While cell membranes and liposomes (vesicles often used for drug-delivery) are created from a double layer of fatty molecules called phospholipids, a poly...

Major WHO study concludes calcium supplements can reduce complications during pregnancy

...Perryman suggested. Now that he can prevent the simulated flaps from opening by using an artificial force, Perryman and co-author Jung-Hsin Lin of National Taiwan University hope to discover and develop real compounds that can regulate flap motion in this manner. Lin is currently assembling a team of resear...

UW-Madison engineers squeeze secrets from proteins

...erent types of confinement. These models were then simulated to gain a better understand of protein stability. Working with the UW-Madison Nanoscale Science and Engineering Center (NSEC), funded by the National Science Foundation, the researchers will continue to refine their models with the goal of confining,...

Pleasing plant shapes explained by new computer model

...angles observed in lilac branching, can be also be simulated using different parameter values. The subject of the study was a plant called Arabidopsis, a small white-flowered plant that is to the world of botany what the fruit fly and white mouse are to zoology. The scientists believe their model will enhanc...

Scientist measures role of science's coolest player: The snow

... Vavrus, a climate modeling specialist, digitally simulated a snow-free world, and measured the impact of missing snow cover on a range of climatic variables including soil temperatures, cloud cover, atmospheric circulation patterns and soil moisture levels. Aside from his temperature-related projections, Va...

Researchers Find Drug May Give Some Cardiac Protection 24 Hours After Heart Attack

...ous studies, Dr. Koch had given EPO at the time of simulated heart attack in an another animal model, and found it protected the animals. But in further studies, Dr. Koch gave Darbepoietin to animals at the time of ischemia and heart attack, one to two hours after, and 24 hours later. In each case, the scient...

Seeing the forest and the trees

...m the Earth Institute at Columbia University. They simulated variations in forest diversity that resulted from a range of different extinction scenarios: those governed by biological characteristics such as low growth rate or limited growing range, those resulting from human activities such as selective loggin...

Researchers learn how blood vessel cells cope with their pressure-packed job

...ct. The 60-cycle-per-minute motion of the indenter simulated the stretching movements of a blood vessel in response to the rising-and-falling blood pressure produced by a beating heart. The researchers also demonstrated that inhibition of either Rho or a related protein called Rho kinase resulted in loss of ...

Preventing a pandemic: Study suggests strategies for containing a flu outbreak

...ct in rural Thailand. With this information, they simulated a population of 500,000 in which individuals mixed in a variety of settings, including households, household clusters, preschool groups, schools, workplaces, and a hospital. Social settings for casual contacts, such as might take place in markets, sh...

Squeezing out dune plants

... Rusty Feagin, Douglas Sherman, and William Grant simulated varying levels of sea-level rise to understand the effects of erosion and development on sand dune plants. Their research appears in the September issue of Frontiers in Ecology and the Environment. In most circumstances, as coastlines erode, plant c...

Motor transport in bio-nano systems
