A pioneering manufacturing process that can turn titanium, stainless steel and many other metals into a new breed of engineering components could have a big impact across industry.
Unlike conventional solid-metal components, the new parts have a tiny lattice-like structure, similar to scaffolding but with poles twice the diameter of a human hair, making them ultra-light. Because loads are channelled along the poles, the parts can comprise up to 70% air while remaining strong enough
Scientists have come up with a “recipe” to help build the world’s first quantum computer – a new generation of super-fast machines set to revolutionise scientific discovery.
Quantum technology could be used to crack codes – valuable for national security – and is already used in some bank transactions. Future developments could involve understanding chemical reactions creating medicines, ultra-fast communications systems and seemingly impossible simulations, such as the creation of
Jürgen Schieble, doctoral candidate at Helsinki’s University of Art and Design Media Lab, wants to create “new types of enriching social experiences.” Combining his experience in mobile technologies with his music performance skills, Jürgen created MobiLenin, a participatory entertainment system. In recognition for his MobiLenin research, Jürgen, together with thesis advisor Timo Ojala, was awarded the Best Arts Paper at the ACM Multimedia 2005 conference in Singapore.

Results from a new study of childhood cancer statistics provide further evidence that common infections affecting mother and baby could play a key role in triggering certain types of the disease.
The research was led by Dr Richard McNally from the University of Newcastle upon Tyne and funded by Cancer Research UK and the Christie Hospital Research Endowment Fund.
The team* analysed a register of cancer cases diagnosed in young children over a period of 45 years. They fou
The outer core of the Earth, whose composition until now has been a mystery, may consist of an alloy of iron and magnesium. This discovery by an international team of scientists with members from Linköping University in Sweden, being published in the journal Physical Review Letters, is, among other things, a major step toward being able to predict earthquakes.
In theoretical and experimental studies under extremely high pressure, the team has succeeded in mixing iron and magnesium.
In conventional dual-mode circuitry both signal lines are just switched by the PIN-diodes. The novel dual-mode switches, which were developed in the department…
OHSU study shows platinum-based ototoxicity in children prevalent, but new drugs offer prevention hope
By 14, Peter Johnson had survived brain cancer and a relapse of the disease in his shoulder. But it was treatment for the last tumor that would create his life’s greatest challenges.
Johnson, now 33, has suffered since 1986 from the effects of ototoxicity, a condition in which platinum-based chemotherapy drugs, such as carboplatin and the more common cisplatin,
A new study finds significant disparities by race and gender in the enrollment of patients into lung cancer clinical trials. Published in the January 15, 2006 issue of CANCER, a peer-reviewed journal of the American Cancer Society, the study indicates that women and African-Americans were least likely to enroll in treatment trials for lung cancer, and identifies a need to improve educational and outreach efforts to make clinical trials available to a wider range of patients.

The reliability of a prostate cancer-screening test may be compromised by lifestyle and demographic factors, according to a new study. Published in the January 15, 2006 issue of CANCER, a peer-reviewed journal of the American Cancer Society, the study reveals the (rate of) change in concentration of prostate specific antigen (PSA) over time–a calculation called PSA velocity–can be significantly affected by age, race, and diet, leading to falsely lower or elevated values and possible misinterpreta
Academic medical centers and not-for-profit hospitals take the lead for-profit hospitals lag behind
A study released today in the Journal of Palliative Medicine confirmed that palliative care programs continue to be a rapidly growing trend in U.S. hospitals – a trend widely regarded to be an improvement in the quality of care of advanced, chronic illness. Researchers at the Mount Sinai Medical Center and the American Hospital Association (AHA) report that the number of palliative
The targeted agent AMN107 can produce dramatic benefits in patients with some forms of leukemia that are resistant to Gleevec, the standard therapy for these cancers, say researchers at The University of Texas M. D. Anderson Cancer Center (meeting abstract #37).
At the 47th Annual Meeting of the American Society of Hematology (ASH), the investigators reported marked improvement in outcome in all three phases of chronic myeloid leukemia (CML) as well as benefit in treating a form
New research has shown that the immune-stimulating hormone known as interleukin-12 (IL-12) can safely be administered with interferon, another immune-system protein, as an experimental therapy for some cancers.
Normally, interferon is used alone to stimulate the immune system to attack certain cancers. This strategy, a form of immunotherapy, is sometimes used to treat melanoma, advanced kidney cancer and other tumors that respond poorly to chemotherapy or radiation therapy. But int
New reports document dramatic changes in the ownership of southern forestland
Two new research studies document dramatic changes in the ownership of Southern forestland and declining markets for its forest products. The Southern Group of State Foresters (SGSF), with the help of scientists from the USDA Forest Service and their university cooperators, recently reviewed the findings of two year-long research projects aimed at understanding trends crucial to the future of southern fo
Neurobiologists have gained new insights into how neurons control growth of the intricate tracery of branches called dendrites that enable them to connect with their neighbors. Dendritic connections are the basic receiving stations by which neurons form the signaling networks that constitute the brain’s circuitry.
Such basic insights into neuronal growth will help researchers better understand brain development in children, as well as aid efforts to restore neuronal connections
Glaciers, rivers and shifting tectonic plates have shaped mountains over millions of years, but earth scientists have struggled to understand the relative roles of these forces and the rates at which they work.
Now, using a new technique, researchers at the University of Michigan, California Institute of Technology and Occidental College have documented how fast glaciers eroded the spectacular mountain topography of the Coast Mountains of British Columbia.

Concerns among health care analysts that the majority of pediatricians in training are now women and that that might cause shortages in the future in pediatric subspecialties appear to be almost entirely unfounded, a new University of North Carolina at Chapel Hill study concludes.
Unlike in the past, women pediatricians are increasingly likely to enter subspecialties, researchers discovered, saying that the news is reassuring.
“This shows that women are breaking into t
