Popular diabetes drugs associated with fractures in type 2 diabetic patients
29-Jul-10
Postmenopausal women with diabetes taking thiazolidinediones (TZDS), including rosiglitazone and pioglitazone, may be at increased risk for fractures according to a new study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM). Men with diabetes taking both loop diuretics and TZDs may also be at increased risk of fractures.
Good and bad in the hands of politicians
29-Jul-10
"In laboratory tests, right- and left-handers associate positive ideas like honesty and intelligence with their dominant side of space and negative ideas with their non-dominant side," says Daniel Casasanto of the Max Planck Institute for Psycholinguistics in Nijmegen, Netherlands. To find out whether people link 'good' with 'dominant' beyond the laboratory, Casasanto and co-author Kyle Jasmin examined spontaneous gestures during positive and negative speech in the final debates of the most recent US presidential elections.
Signs of reversal of Arctic cooling in some areas
29-Jul-10
Parts of the Arctic have cooled clearly over the past century, but temperatures have been rising steeply since 1990 also there. This is the finding of a summer temperature reconstruction for the past 400 years produced on the base of tree rings from regions beyond the Arctic Circle. German and Russian researchers analysed tree growth using ring width of pine from Russia's Kola Peninsula and compared their findings with similar studies from other parts of the Arctic.

Intensive chemotherapy may be harmful to most older patients with acute myeloid leukemia
29-Jul-10
The prognosis for nearly three-quarters of elderly patients on intensive chemotherapy for acute myeloid leukemia (AML) is poor, with a median survival of less than six months, according to a study published online today in Blood, the journal of the American Society of Hematology. AML is the most common form of acute leukemia among adults and is a rapidly growing cancer of the bone marrow that requires immediate treatment. The average age at diagnosis is 67, and more than 12,000 people will be diagnosed with AML this year (according to the National Cancer Institute).

Model describes universe with no big bang, no beginning, and no end
29-Jul-10
(PhysOrg.com) -- By suggesting that mass, time, and length can be converted into one another as the universe evolves, Wun-Yi Shu has proposed a new class of cosmological models that may fit observations of the universe better than the current big bang model. What this means specifically is that the new models might explain the increasing acceleration of the universe without relying on a cosmological constant such as dark energy, as well as solve or eliminate other cosmological dilemmas such as the flatness problem and the horizon problem.
Panasonic to buy out Sanyo, Panasonic Electric

Nanotechnology for water purification
29-Jul-10
Nanotechnology refers to a broad range of tools, techniques and applications that simply involve particles on the approximate size scale of a few to hundreds of nanometers in diameter. Particles of this size have some unique physicochemical and surface properties that lend themselves to novel uses. Indeed, advocates of nanotechnology suggest that this area of research could contribute to solutions for some of the major problems we face on the global scale such as ensuring a supply of safe drinking water for a growing population, as well as addressing issues in medicine, energy, and agriculture.

Astronomers Find Planets in Unusually Intimate Dance around Dying Star
29-Jul-10
Hundreds of extrasolar planets have been found over the past decade and a half, most of them solitary worlds orbiting their parent star in seeming isolation. With further observation, however, one in three of these systems have been found to have two or more planets. Planets, it appears, come in bunches. Most of these systems contain planets that orbit too far from one another to feel each other's gravity. In just a handful of cases, planets have been found near enough to one another to interact gravitationally.
