A group of scientists from the University of Gothenburg and the Royal Institute of Technology (KTH), Sweden, have become the first group in the world to demonstrate that theories about nanoscale spin waves agree with observations. This opens the way to replacing microwave technology in many applications, such as mobile phones and wireless networks, by components that are much smaller, cheaper, and that require less resources. The study has been published in the scientific journal Nature Nanotechnology, the most prestigious journal in nanoscience.

Baltimore, MD – Sept. 6, 2011 – Young women with early-stage breast cancer have similar survival rates with a lumpectomy and radiation treatment, known as breast-conservation therapy, as with mastectomy, a new study conducted at the University of Maryland has found. The results of the analysis of nearly 15,000 patients listed in a nationwide cancer registry will be presented at the 2011 Breast Cancer Symposium to be held Sept. 8-11 in San Francisco.
A major new international study involving researchers from the Sahlgrenska Academy at the University of Gothenburg and Sahlgrenska University Hospital has revealed that aspirin, statins, beta blockers and ACE inhibitors are prescribed far too infrequently. They are cheap, preventive medicines that could prevent a huge number of deaths from heart attacks and strokes.
The result of a research collaboration between 17 countries, the study is being published in the highly revered medical journal The Lancet.
Patients who have received high doses of chemotherapy may find it harder to express themselves verbally, according to new research from the Sahlgrenska Academy at the University of Gothenburg, Sweden. Speech difficulties among cancer patients who received chemotherapy treatment were two times higher than among those who did not.
The study has been published in the scientific journal Acta Oncologica. Almost one thousand men who had survived testicular cancer were asked to respond to a questionnaire about how they felt eleven years following their diagnosis.
CHICAGO -- Researchers at Northwestern University Feinberg School of Medicine have discovered why the immune cells of people with rheumatoid arthritis become hyperactive and attack the joints and bones. The immune cells have lost their bouncer, the burly protein that keeps them in line the same way a bouncer in a nightclub controls rowdy patrons.
Not all trans fats are created equal and it's time for a change in nutrition labels to reflect this, particularly when it comes to dairy and beef products.
According to a scientific review published in the latest edition of Advances in Nutrition, natural trans fats produced by ruminant animals such as dairy and beef cattle are not detrimental to health and in fact show significant positive health effects. Some evidence even links these natural trans fats to reduced risk of cardiovascular disease and cancer.
Not all trans fats are created equal and it's time for nutritional labels to reflect that reality, says a University of Alberta nutrition expert.
According to a scientific review conducted by Spencer Proctor, along with Canadian and international colleagues, natural trans fats produced by ruminant animals such as dairy and beef cattle are not detrimental to health. In fact, they show significant positive health effects and some evidence even links these natural trans fats to reduced risk of cardiovascular disease and cancer.
COLLEGE STATION, Sept. 7, 2011 – Like clues from an Agatha Christie mystery novel, trees can provide secrets about past events, and their rings are especially good at providing information about fires, some of which happened hundreds of years ago, according to studies from a Texas A&M University researcher.
Scientists are reporting development of a long-sought new way to detect the activity of proteins that bind to the DNA in genes, often controlling the activity of genes in ways that make cells do everything from growing normally to becoming cancerous. Their report appears in the Journal of the American Chemical Society.
Every cell has thousands of proteins whose activity and lifetime must be regulated to control the cellular life cycle from cell division to cell death. The heat shock protein Hsp90 plays a key role in this process. It is a so-called chaperone, a quality controller, as it were. It monitors and controls the quality and activity of many important signal proteins and helps them take on the right form. When the cell is exposed to high stress levels from heat or a lack of oxygen, Hsp90 is produced in larger quantities to shield its partner proteins from damage.
For the first time, new research shows that patterns of alcohol consumption – a drink or two every night, or several cocktails on Friday and Saturday nights only – may be more important in determining alcohol's influence on heart health than the total amount consumed.
China needs to change where it sites its nature reserves and steer people out of remote rural villages toward cities to protect its valuable but threatened wild plant resources, according to an article published in the September issue of BioScience.
Adding a powder that contains several vitamins and minerals, including iron, zinc and vitamin A, to the semi-solid foods taken by infants and children between six months and two years of age, can reduce their risk of anaemia and iron deficiency. This is the conclusion of a new Cochrane Systematic Review.
Fungi that cause severe infections in those with compromised immune systems are resisting the action of the latest group of antifungal drugs. Uncovering their strategies for doing this will lead to more effective treatments, says a scientist speaking at the Society for General Microbiology's Autumn Conference at the University of York.
