How Would Einstein Use E-mail?
The additional offender groans.
You’re not as different from Albert Einstein and Charles Darwin after all, at least when it comes to patterns of correspondence.
A new Northwestern University study of human behavior has determined that those who wrote letters using pen and paper — long before electronic mail existed — did so in a pattern similar [...]
Nanosponge drug delivery system better than direct injection
When loaded with an anticancer drug, a delivery system based on a novel material called nanosponge is three to five times more effective at reducing tumor growth than direct injection.
That is the conclusion of a paper published in the June 1 issue of the journal Cancer Research.
“Effective targeted drug delivery systems have been a dream [...]
New mechanism of pancreatic cancer discovered
[PRESS RELEASE, 31 May 2010] A new study from Karolinska Institutet shows how two types of cell change interact in the development of cancer. The results can improve the chances of early discovery of cancer – including pancreatic cancer, one of the deadliest forms of the disease.
Cancer of the pancreas is a form of cancer [...]
Patients’ problems often misunderstood by caring staff
Problems patients experience due to dental or skin conditions are often differently perceived by care providers. This is shown in a dissertation by Francesca Sampogna, a researcher in epidemiology at Istituto Dermopatico dell’Immacolata in Rome.
“To limit this problem, specific courses in communication should be included in the training of health-care personnel,” she says. On Friday, [...]
Exercise improves the defenses of cancer patients, experts say
Cancer patients should engage in physical exercise because it improves the body’s defenses, aiding recovery and preventing clinical complications different side-motivation and self-esteem, increase social relations and greater capacity for empathy, and increased well-being and personal happiness, as experts have pointed out during the day ‘Sport and oncological diseases, an alliance of patient benefit. ” [...]
A new cancer vaccine starves tumours of blood
[PRESS RELEASE, 24 May 2010] A DNA-vaccine that restricts the supply of blood to tumours has been developed by scientists at the Swedish medical university Karolinska Institutet. The vaccine slows the growth of breast cancer tumours in mice.
If a cancer tumour is to become larger than a few millimetres it must be able to stimulate [...]
New invention regulates nerve cells electronically
A major step toward being able to regulate nerve cells externally with the help of electronics has been taken by researchers at Linköping University and the Karolinska Institute in Sweden. The breakthrough is based on an ion transistor of plastic that can transport ions and charged biomolecules and thereby address and regulate cells.
The invention, which [...]

Toxin Does Not Affect MRSA-Induced Pneumonia
A group led by Dr. James M. Musser at the Center for Molecular and Translational
Human Infectious Diseases Research of The Methodist Hospital Research Institute
in Houston, Texas has demonstrated that the cytotoxin Paton-Valentine leukocidin
(PVL) does not affect methicillin-resistant Staphlococcus aureus (MRSA)-induced
pneumonia. Their report can be found in the March 2010 issue [...]
Laser surgery technique gets new life in art restoration
A laser technique best known for its use to remove unwanted tattoos from the
skin is finding a second life in preserving great sculptures, paintings and
other works of art, according to an article in ACS’ monthly journal, Accounts of
Chemical Research. The technique, called laser ablation, involves removing
material from a solid surface by vaporizing the material with [...]
Researchers trace HIV mutations that lead to drug resistance
Chemists at UC San Diego and statisticians at Harvard University have developed a novel way to trace mutations in HIV that lead to drug resistance. Their findings, once expanded to the full range of drugs available to treat the infection, would allow doctors to tailor drug cocktails to the particular strains of the virus found [...]
