The doctoral dissertation of Gilad Sperling, MBA, “Product, Operation and Market Strategies of Technology-Intensive Born Globals. The case of Israeli Telecommunication Born Globals,” in the field of International Business, will be publicly examined on Friday, September 23, 2005, at the Helsinki School of Economics (HSE). The opponent is Senior Lecturer, Dr. Tamar Almor-Ellemers (Tel Aviv University, College of Management) and the custos is Emeritus Professor Reijo Luostarinen (HSE).

It may be possible to halt cancer in its tracks by blocking a gene critical to building tumour supply lines, according to new research carried out at the University of Queensland, Australia.
Most tumours need a blood supply to grow.
Researchers at the Institute for Molecular Bioscience have found that when new blood vessels form – in developing embryos and in tumours – a gene, known as Sox18, switches on for just 48 hours.
“In adult mice, we have found that i
Large Population of Galaxies Found in the Young Universe with ESO’s VLT
The Universe was a more fertile place soon after it was formed than has previously been suspected. A team of French and Italian astronomers [1] made indeed the surprising discovery of a large and unknown population of distant galaxies observed when the Universe was only 10 to 30% its present age.
This breakthrough is based on observations made with the Visible Multi-Object Spectrograph (VIMOS)
By specially tagging the outer and inner membranes of red blood cells infected with the malaria parasite and tracking the cellular changes that precede the cell bursting event that disperses parasites to other blood cells, a group of researchers has deepened our understanding of how the malaria pathogen destroys the cells in which it resides. The work is reported in Current Biology by Joshua Zimmerberg and colleagues at the U.S. National Institutes of Health.

Researchers have uncovered a significant contributing factor to interferon resistance of malignant melanoma cells. The finding represents a step forward in understanding the molecular events that govern the growth of this type of cancer and the changes in gene expression and cellular signaling that underlie resistance to established therapies.
Malignant melanoma is the deadliest form of skin cancer, and if not treated successfully, it can spread to affect the liver, lungs, or bra
Chronically high levels of insulin, as is found in many people with obesity and Type II diabetes, may block specific hormones that trigger energy release into the body, according to researchers at the University of California, San Diego (UCSD) School of Medicine. Their findings, which may point to new approaches to developing improved treatment options for the disease, will be published in the September 22 issue of the journal Nature.

An advanced research weather model run by the National Center for Atmospheric Research (NCAR) is following Hurricane Rita to give scientists a taste of how well forecast models of the future may predict hurricane track, intensity, and important rain and wind features. Tap into the model’s daily storm projection at www.ucar.edu.
With its high-resolution grid of data points just four kilometers (about 2.5 miles) apart, the model can project the location of fine-scale rain bands
We all know that if you put your hand over an open flame it’s very painful. What you may not know is that, for some people, just lying under a blanket is painful as well. They have neuropathic pain–annoying, chronic pain that comes from a diseased nerve cell rather than a specific stimulus. Feeling phantom pain in a missing limb is another, more famous, example.
Experts say up to two percent of the U.S. population suffers from neuropathic pain. But this pain generally resp
By examining how proteins have evolved, UT Southwestern Medical Center researchers have discovered a set of simple “rules” that nature appears to use to design proteins, rules the scientists have now employed to create artificial proteins that look and function just like their natural counterparts.
In two papers appearing in the Sept. 22 issue of the journal Nature, Dr. Rama Ranganathan, associate professor of pharmacology, and his colleagues detail a new method for creating art
Aloe vera gel is best known for its therapeutic effect on burned or irritated skin, but in the future you could be eating the gel as a healthful additive to your fruits and veggies. Researchers in Spain say they have developed a gel from the tropical plant that can be used as an edible coating to prolong the quality and safety of fresh produce. The gel, which does not appear to affect food taste or appearance, shows promise as a safe, natural and environmentally-friendly alternative to conventi
Researchers have identified a molecular suspect in a disorder similar to multiple sclerosis (MS) that attacks the optic nerve and spinal cord, according to a report presented at the 130th annual meeting of the American Neurological Association in San Diego. The protein, called aquaporin-4, is a channel protein that allows water to move in and out of cells.
“Aquaporin-4 is the first specific molecule to be defined as a target for the autoimmune response in any form of MS,” said
A cluster of genes on chromosome six is the only one that plays a significant role in multiple sclerosis (MS), according to the most complete genetic study to date in the disorder, presented at the 130th annual meeting of the American Neurological Association in San Diego.
“Our results confirm the strong role of the major histocompatibility complex genes in MS, and provides a definitive statement that no other region of the genome harbors a gene with a similar overall influence on
New research just released in the September issue of Plant Disease suggests that weeds commonly found in California’s wine country may enable the spread of Pierce’s disease of grapes, one of the most destructive plant diseases affecting grapes.
Pierce’s disease is caused by Xylella fastidiosa, a bacterium transmitted by sharpshooters and spittlebugs. In response to outbreaks of Pierce’s disease in central California, plant pathologists studied 29 weed species commonly found in
Halloween may seem like so much harmless fun, a time when adults enjoy laughing in the face of death, and implore their young children to do the same. According to a Penn State researcher, however, the humor of tombstones, monsters and other scary elements is often lost on kids at the ripe age of 6 or 7–many of whom don’t find the holiday the least bit funny.

For the first time, scientists have identified an ant species that produces its own natural herbicide to poison unwanted plants.
Stanford University biologist Deborah M. Gordon and her co-workers describe the findings in the Sept. 22 issue of the journal Nature. The discovery was made during a four-year field study led by Stanford graduate student Megan E. Frederickson in the Amazon jungle of western Peru. The research focused on devil’s gardens, mysterious tracts of vegetati
Test looks at 22 biomarkers; results more accurate than PSA
Researchers at the University of Michigan Comprehensive Cancer Center have identified a panel of 22 biomarkers that together provide a more accurate screening for prostate cancer than the current prostate specific antigen, or PSA, test. The study appears in the Sept. 22 issue of the New England Journal of Medicine.
Researchers looked at blood samples taken from 331 prostate cancer patients prior to surgery, and
