MIT lab works to mimic spider silk

As a fiber, spider silk is so desirable that scientists have spent decades trying to find a way to mimic it. A team at MIT has been tackling the problem from two directions.

“The main goal is to be able to reproduce the enormous energy absorption and strength-bearing properties of spider silk,” said Paula T. Hammond, an associate professor in MIT’s Department of Chemical Engineering. “[We want] to be able to obtain a material in large quantities and cheaply … without DNA techniques, which a

Intensive in-hospital monitoring reduces premature delivery of monoamniotic twins, improves survival

Monoamniotic twins: An 8-year experience

With intensive and constant in-hospital fetal monitoring of monoamniotic (MA) twins, delivery can be delayed to beyond 34 weeks, and the live discharge rate can approach that of other twin pregnancies. This is significant because, historically, twins who shared a common amniotic sac had only about a 50 percent chance of both twins surviving. Those who did survive were typically delivered prematurely, resulting in a higher risk of severe health

Researchers Discover Effective Method For Killing Prostate Cancer Cells

By blocking a protein key to prostate cancer cell growth, researchers at the Lombardi Cancer Center at Georgetown University have discovered a way to trigger extensive prostate cancer cell death. This finding opens a new window for developing targeted treatments aimed at destroying prostate cancer cells before they have the opportunity to grow or spread. The study is published in the April 29 online issue of the Journal of Biological Chemistry.

“By preventing the Stat5 protein from being a

UC Riverside scientists contribute to study that unveils genome sequence of bread mold

New knowledge will provide insight into organisms important to agriculture, medicine, the environment and commerce

In the April 24, 2003, issue of the journal Nature, scientists, including UC Riverside’s Katherine A. Borkovich, assistant professor in the department of plant pathology, and her postdoctoral fellow, Svetlana Krystofova, present the entire list of genes found in the Neurospora genome. (A genome is all the DNA in an organism, including its genes.) The scientists’ analysis

A new, dechlorinating bacterium

Several industrial activities of the previous decades resulted in serious contamination of groundwater. For instance, polyvinyl chloride (PVC) production and related activities cause annual underground releases of 137 tonnes of 1,2-dichloroethane (1,2-DCA) in the USA (1988-1999). The latter molecule has an environmental half-life of about 50 years, is the most abundant groundwater pollutant of all chloroethenes and –ethanes, and is a suspected carcinogen. Its physico-chemical properties result in a s

Sars Could Have Less Serious Effects On Young Children

Preliminary findings from Hong Kong investigators fast-tracked for publication on THE LANCET’s website-www.thelancet.com – outline how severe acute respiratory syndrome (SARS) may have a less serious effect on young children compared with teenagers and adults.

There have been no childhood deaths from SARS up to April 25, 2003. Tai Fai Fok from the Chinese University of Hong Kong and colleagues prospectively studied the first 10 children with SARS who received treatment during the early phase
