Say hello to a new travel experience

Feb. 24, 2014, 7 p.m.

AUSTRALIA'S newest travel experience has hit Mount Isa.

THE TRAVEL EXPERTS: The helloworld team - Cassie Williams, Kim Donaldson, Michele Corcoran and Jess Grummitt.

AUSTRALIA'S newest travel experience has hit Mount Isa.

The Jetset Travelworld Group has consolidated its smaller brands, phasing out Harvey World Travel and creating helloworld.

The change comes as a modern and fresh upgrade, providing a new travel experience to Mount Isa.

Mount Isa helloworld manager Michele Corcoran wanted to thank the community for its continued support throughout the transition and said she and her team were looking forward to treating existing loyal clients and fresh new faces to the helloworld experience.

``Over the next few months we will continue to change and grow, providing you with exceptional service and lasting memories of amazing holidays,'' she said.

Mrs Corcoran said that despite the change, it was business as usual at the same location with the same friendly faces and same great service.

``We want the community to know that it is a new brand but we are still the local go-to travel company in town.''

STAP stem cell doubts keep proliferating

Posted on by

Doubts keep growing about the stunning discovery that super stem cells could be created merely by placing white blood cells from young mice in acid or otherwise stressing them, says Paul Knoepfler, a stem cell researcher at UC Davis.

Among other inconsistencies, Knoepfler referred to several unexplained anomalies in images of these STAP cells in two papers, published by the prestigious journal Nature on Jan. 29. One image appears to suggest signs that virtually all cells treated with an acid bath were being reprogrammed, a result that would be extraordinary. Stem cell reprogramming to date has been inefficient, with a low percentage of treated cells being reprogrammed.

"The more I look at these two STAP papers, the more concerned I get ... The bottom line for me now is that some level a part of me still clings to a tiny and receding hope this has all been overblown due to simple misunderstandings, but that seems increasingly unlikely," Knoepfler wrote Sunday on his blog, IPS Cell.

This undated image made available by the journal Nature shows a mouse embryo formed with specially-treated cells from a newborn mouse that had been transformed into stem cells. Researchers in Boston and Japan say they created stem cells from various tissues of newborn mice. If the same technique works for humans, it may provide a new way to grow tissue for treating illnesses like diabetes and Parkinson's disease. The report was published online on Wednesday, Jan. 29, 2014 in the journal Nature. (AP Photo/RIKEN Center for Developmental Biology, Haruko Obokata)

Nature is conducting its own investigation, Knoepfler noted. But in addition, the journal should release "unmodified, original versions" of the images and data in the papers, Knoepfler wrote.

The images contained "minor errors" that didn't change the basic findings, said Charles Vacanti, a Harvard University professor who is part of the scientific team reporting the discovery, according to a Feb. 22 article in a Japanese newspaper, the Asahi Shimbun.

Controversy is normal for any major scientific advance. Skeptics must be converted, and the only way to do that is to show the data. The 1997 announcement of the first mammalian clone, Dolly the sheep, was greeted with considerable doubt because it was believed that genetic imprinting made such cloning impossible. But others were eventually able to confirm the finding.

In this case, doubters say such an apparently easy method of reprogramming cells would generate pluripotent stem cells far too easily, because stress is common in animals. Such stem cells are known to cause tumors, so evolution should have selected against such a response.

Nature's own role has been criticized. The journal was taken to task for its handling of online journalism Feb. 20 by another stem cell blogger, Alexey Bersenev. He chided Nature for not linking to sources.

"In scientific journalism, every claim must be linked to appropriate original source," Berseney wrote. "Nature consistently refuses to acknowledge bloggers, online discussions and other web resources with valid credible information. This is not acceptable for sci journalism."

Immune cells regulate blood stem cells, research shows

Posted on by

Researchers in Bern have discovered that, during a viral infection, immune cells control the blood stem cells in the bone marrow and therefore also the body's own defenses. The findings could allow for new forms of therapy, such as for bone marrow diseases like leukemia.

During a viral infection, the body needs various defense mechanisms -- amongst other things, a large number of white blood cells (leukocytes) must be produced in the bone marrow within a short period of time. In the bone marrow, stem cells are responsible for this task: the blood stem cells. In addition to white blood cells, blood stem cells also produce red blood cells and platelets.

The blood stem cells are located in specialized niches in the bone marrow and are surrounded by specialized niche cells. During an infection, the blood stem cells must complete two tasks: they must first recognise that more blood cells have to be produced and, secondly, they must recognise what kind of.

Now, for the first time, researchers at the Department of Medical Oncology at the University of Bern and Bern University Hospital headed by Prof. Adrian Ochsenbein have investigated how the blood stem cells in the bone marrow are regulated by the immune system's so-called T killer cells during a viral infection. As this regulation mechanism mediated by the immune system also plays an important role in other diseases such as leukemia, these findings could lead to novel therapeutic approaches. The study is being published in the peer-reviewed journal "Cell Stem Cell" today.

T Killer cells trigger defenses

One function of T killer cells is to "patrol" in the blood and remove pathogen-infected cells. However, they also interact with the blood stem cells in the bone marrow. The oncologists in Bern were able to show that messenger substances secreted by the T killer cells modulate the niche cells. In turn, the niche cells control the production and also the differentiation of the blood stem cells.

This mechanism is important in order to fight pathogens such as viruses or bacteria. However, various forms of the bone marrow disease leukemia are caused by a malignant transformation of exactly these blood stem cells. This leads to the formation of so-called leukemia stem cells. In both cases, the mechanisms are similar: the "good" mechanism regulates healthy blood stem cells during an infection, whilst the "bad" one leads to the multiplication of leukemia stem cells. This in turn leads to a progression of the leukemia.

This similarity has already been investigated in a previous project by the same group of researchers. "We hope that this will enable us to better understand and fight infectious diseases as well as bone marrow diseases such as leukemia," says Carsten Riether from the Department of Clinical Research at the University of Bern and the Department of Medical Oncology at Bern University Hospital and the University of Bern.
