Blood 'fingerprints' for cancer
Serum microRNAs (miRNAs) can serve as biomarkers for the detection of diseases including cancer and diabetes, according to research published online this week in Cell Research. The findings pave the way for a revolutionary non-invasive diagnostic tool.

Revising the rise of the sea
By the year 2100, some models of sea level fluctuations predict a rise of two meters caused by the disintegration of Greenland and Antarctic ice. But, researchers now say that such an increase is unrealistic, and a more accurate estimate of the rise by 2100 would be somewhere between 0.8 and two meters, researchers report in the Sept. 4 issue of Science.

Invisibility undone
Harry Potter beware! A team of Chinese scientists has developed a way to unmask your invisibility cloak. According to a new paper in the latest issue of Optics Express, the Optical Society's open-access journal, certain materials underneath an invisibility cloak would allow invisible objects be seen again.

Comparison of angiography contrast agents finds little difference in certain outcomes
Use of sodium bicarbonate for hydration during coronary angiography for patients with kidney disease did not reduce the risk of developing serious kidney problems related to the use of contrast agents, compared to use of sodium chloride, according to a study in the Sept. 3 issue of JAMA.

Peptide promotes a healthy brain
The amyloid-ß peptide (Aß) is deposited in the brains of patients with Alzheimer’s disease, and it is targeted in many potential treatments of the disease. Its actions and regulation in the living brain are not well understood. Now, researchers show that the levels of Aß peptide in the human brain are directly related to the neurological status of that individual, researchers report in the Aug. 28 issue of Science.

Consumption of nuts, corn or popcorn not associated with increased risk of diverticulosis in men
Contrary to a common recommendation to avoid eating popcorn, nuts and corn to prevent diverticular complications, a large prospective study of men indicates that the consumption of these foods does not increase the risk of diverticulosis or diverticular complications, according to a study in the Aug. 27 issue of JAMA.

2 face transplants, 1 after bear attack and 1 for large facial tumor, show promising results
A face transplant given to a man two years ago after he had part of his face torn off in a bear attack has shown promising results. The procedure could thus be used for long-term restoration of serious facial disfigurement, although it is not without complications. These are the conclusions of authors of the first of two articles on face transplantation published in this week's edition of the Lancet.

Undecided voters -- are they really?
Say it's election time and you can't decide which of two political candidates deserves your vote. You could plan to study up on the candidates and their platforms, but, in fact, you may have unconsciously made your decision already, suggests a new study that may help experts better predict election outcomes from polling data, researchers report in the Aug. 21 issue of Science.
