Nano world: Where towers construct themselves

Imagine a tower builds itself into the desired structure only by choosing the appropriate bricks. Absurd – and however, in the nano world this is reality: There an unordered crowd of components can initiate the formation of an ordered structure – a process known as self-assembly. The physicists Christos Likos (University of Vienna), Emanuela Bianchi and Gerhard Kahl (both Vienna University of Technology) investigate how they can control the ordering of such self-assembling structures and found out how to switch the assembly process on and off.

No apparent link between chronic cerebrospinal venous insufficiency and MS

There appears to be no link between chronic cerebrospinal venous insufficiency and multiple sclerosis (MS), according to new research published in CMAJ (Canadian Medical Association Journal).

Success for scientists in the academic job market is highly predictable

The number of scientists in training vastly exceeds the number that will successfully land a faculty position at an academic institution. Now, researchers report in the Cell Press journal Current Biology on June 2 that an individual scientist's chances are very predictable based solely on his or her publication record.

Rolling old river is indeed changing

This release is also available in Chinese on EurekAlert! Chinese.

The Hudson River has changed in many far-reaching ways over the past quarter-century as a result of human activity, reports a team of researchers in the June issue of BioScience. Zebra mussels and other invasive species have changed the river's ecology—although the influence of the zebra mussels now seems to be waning.

No harm in yoga: But not much help for asthma sufferers

ARLINGTON HEIGHTS, Ill. (May 29, 2014) – Yoga has long been promoted as a method for improving physical and mental well-being. And although yoga is often suggested to asthma sufferers to help alleviate symptoms, a new study found little evidence that yoga will improve symptoms.

Long-term results encouraging for combination immunotherapy for advanced melanoma

New Haven, CT — The first long-term follow-up results from a phase 1b immunotherapy trial combining drugs for advanced melanoma patients has shown encouraging results — long-lasting with high survival rates — researchers report. First author Mario Sznol, M.D., professor of medical oncology at Yale Cancer Center, is presenting the updated data at the 2014 annual conference of the American Society of Clinical Oncology (ASCO) in Chicago.

CU Denver study shows public health often ignored in transportation policy

DENVER (June 2, 2014) – A new study from the University of Colorado Denver shows public health issues are often ignored in many transportation projects, especially when major roads are built through lower-income neighborhoods.

Air pollution, crime and numerous traffic hazards, the study said, point to a serious and persistent gap between public health and planning.

Surgeons report fewer postoperative blood clots using risk-based preventive measures

Chicago (June 2, 2014): Surgery patients are much less likely to get a blood clot in the lower extremities or lungs if they receive preventive treatment based on their individual clotting risk, in addition to walking soon after the operation.

'Healthy' component of red wine, resveratrol, causes pancreatic abnormalities in fetuses

Here's more evidence that pregnant women should be careful about what they eat and drink: A new research report appearing in the June 2014 issue of The FASEB Journal shows that when taken during pregnancy, resveratrol supplements led to developmental abnormalities in the fetal pancreas. This study has direct relevance to human health--Resveratrol is widely used for its recognized health benefits, and is readily available over the counter.

New therapies harness power of the immune system against cancer

CHICAGO – New research on innovative immunotherapies for advanced or high-risk melanoma and cervical cancer were presented today at the 50th Annual Meeting of the American Society of Clinical Oncology (ASCO). These treatments – used alone or in combination – fight cancer by activating and amplifying the body's immune response to the disease.

Doing more with less; in cellulo structure determinations

Anyone involved in macromolecular crystallography will know that for many years scientists have had to rely on a multi-stage process utilizing protein, usually expressed in engineered cells, which is then extracted and purified before crystallization in vitro and finally prepared for analysis.

BRCA2 gene now connected to lung cancer, doubling a smoker's risk

New research confirms a vulnerability to lung cancer can be inherited and implicates the BRCA2 gene as harboring one of the involved genetic mutations. An international consortium of scientists including investigators at the Institute for Cancer Research in London, the International Agency for Research on Cancer in Lyon, the National Cancer Institute in Bethesda, Harvard, and Dartmouth used integrated results from the 1000 Genomes Project with genetics studies of lung cancer to complete the investigation published on June 1, 2014 in Nature Genetics.

Small businesses less likely to offer health promotion programs

Employees at small businesses are less likely to have access to worksite wellness programs, according to a research review in the May Journal of Occupational and Environmental Medicine, official publication of the American College of Occupational and Environmental Medicine (ACOEM).

CPAP rapidly improves blood pressure and arterial tone in adults with sleep apnea

DARIEN, IL – A new study suggests that continuous positive airway pressure (CPAP) therapy rapidly improves blood pressure and arterial tone in adults with obstructive sleep apnea (OSA).

Results show that there was a significant reduction in systolic and diastolic blood pressures among sleep apnea patients who were compliant with CPAP therapy for three months. Successful treatment of sleep apnea also was associated with decreased vascular tone and arterial stiffness. Following one week of treatment withdrawal, these improvements disappeared and reverted to baseline values.

Does your stomach bacteria protect you from obesity?

The germ Helicobacter pylori is the cause of most stomach ulcers, but new research in Alimentary Pharmacology & Therapeutics suggests that treating the bacteria is linked to weight gain.

It is estimated that 50% of the global population may be infected with H. pylori; however, only 20% of infected people experience symptoms. New evidence suggests that patients treated for the infection developed significant weight gain compared to subjects with untreated H. pylori colonization.
