Calvert Labs is offering clients the same kind of 24/7 on-demand smartphone access to study information that’s available to the rest of the world for news and sports. It’s linked a project-tracking iPhone application with a near-real-time and on-demand filtered information source for preclinical researchers.

Another week, another nano-prefixed word to add to the lexicon: NanoPopcorn. This one comes courtesy of researchers at Jackson State University in Mississippi who created a popcorn-shaped nanoparticle that can perform three separate tasks. First, it can detect as few as 50 prostate cancer cells, then it switches into thermal scalpel mode to cook the cancer cells to death, and it can track the response of cancer cells to the therapy.

There are many possible ways to kill a cancer cell, and one of them is to cook them to death. There are nanoparticles worth their weight in gold to do just that. Researchers at the Niels Bohr Institute at the University of Copenhagen are experimenting with tiny gold particles’ ability to melt the lipid membranes surrounding cells, paving the way for pinpoint precision when attacking tumors.

Researchers in the United States have developed a medical model for regenerating bladders using stem cells harvested from a patient’s own bone marrow. The research, published in Stem Cells, is especially relevant for paediatric patients suffering from abnormally developed bladders, but also represents another step towards new organ replacement therapies.

UCSF researchers have shown for the first time that the human fetal immune system arises from an entirely different source than the adult immune system, and is more likely to tolerate than fight foreign substances in its environment. The finding could lead to a better understanding of how newborns respond to both infections and vaccines, and may explain such conundrums as why many infants of HIV-positive mothers are not infected with the disease before birth, the researchers said.
No, gold-plated liposomes are not a luxury gift that you’d find in your Christmas stocking, but they could someday give cancer patients the gift of life by selectively knocking out cancer cells while leaving healthy ones alone. This holiday gift comes courtesy of Marek Romanowski, an associate professor of biomedical engineering in the University of Arizona’s College of Engineering, along with the grad students in his lab, Xenia Kachur and Sarah Leung.

Researchers surveyed the Facebook activities of 405 postgraduate trainee doctors at Rouen University Hospital in France and found that almost three out of four had a Facebook profile. One in four logged on to the site several times a day, and half logged on several times a week.

A fledgling biotech company is pursuing some of the research into cancer stem cells undertaken by Robert Weinberg at the Massachusetts Institute of Technology and the Whitehead Institute for Biomedical Research. Verastem raised $16 million a few weeks ago with an eye on developing new treatments tailored for fighting the unique stem cells, which are often left untouched by the current generation of chemotherapies.

Handheld devices such as personal digital assistants (PDAs) and the iPod Touch are prevalent among doctors. However a recent study shows that these devices may be particularly useful for emergency radiologists, who in the near future, may be able to use them for teleconsultation and emergency procedures, according to a study published in the American Journal of Roentgenology.

While it has become clear in recent years that susceptibility to pain has a strong inherited component, very little is known about actual “pain genes” and how they work. In the November 12th issue of Cell, researchers at Children’s Hospital Boston and their collaborators report on a novel human pain gene. People with minor variations in this gene showed clear differences in susceptibility to acute heat pain and chronic back pain. Corroborating mouse studies give some clues as to how the gene controls pain sensitivity. The gene was uncovered in a genome-wide hunt for pain genes in fruit flies, which revealed hundreds of other candidate pain genes that await further study.
