Phobos from Mars Express

Why is this small object orbiting Mars? The origin of Phobos, the larger of the two moons orbiting Mars, remains unknown. Phobos and Deimos appear very similar to C-type asteroids, yet gravitationally capturing such asteroids, circularizing their orbits, and dragging them into Mars' equatorial plane seems unlikely. Pictured above is Phobos as it appeared during last week's flyby of ESA's Mars Express, a robotic spacecraft that began orbiting Mars in 2003. Visible in great detail is Phobos' irregular shape, strangely dark terrain, numerous unusual grooves, and a spectacular chain of craters crossing the image center. Phobos spans only about 25 kilometers in length and does not having enough gravity to compress it into a ball. Phobos orbits so close to Mars that sometime in the next 20 million years, tidal deceleration will break up the rubble moon into a ring whose pieces will slowly spiral down and crash onto the red planet. The Russian mission Phobos-Grunt is scheduled to launch and land on Phobos next year.

Ancient Ottawa worm wiggles into the spotlight

An extremely rare fossil that predates dinosaurs was pulled from the muck at a downtown Ottawa construction site - then lay virtually unnoticed for more than a decade.

Va fined $227K for flawed cancer treatments in Pa.

PHILADELPHIA (AP) — The Department of Veterans Affairs was fined $227,500 after incorrect radiation doses were given to 97 veterans with prostate cancer at the Philadelphia VA Medical Center, a federal agency announced Wednesday.

The Nuclear Regulatory Commission said the fine is the second largest it has ever levied for medical errors.

PTH battles TGF-? in bone

Bone remodelling in vertebrates is coordinately regulated by the opposing effects of parathyroid hormone (PTH) and transforming growth factor-beta (TGF-?). PTH couples the processes of bone resorption and formation by enforcing simultaneous internalization of TGF-? type II receptor (T?RII) and PTH type 1 receptor (PTH1R), which attenuates both TGF-? and PTH signalling in vivo.

Illuminated Cloud Trails Above Greece

It may appear to be day, but it's night. Those wondrous orange streaks may appear to be rays from the setting Sun, but they're actually thin clouds illuminated by the Moon as they quickly streaked toward the distant horizon. The thick clouds on the far left may appear to have many layers, but actually they are just a few simple clouds captured on numerous separate exposures. What is surely true, though, is that the above time lapse image sequence was taken over two hours, about two weeks ago, in Sounio, Greece. Also, those really are star trails swirling around the north star Polaris on the upper right of the image. But what about the building in the foreground? It may appear to be a famous ancient structure, but it's actually a small deserted church built only last century.

ASTRO publishes supplement on protecting cancer patients by reducing radiation doses, side effects

The Quantitative Analysis of Normal Tissue Effects in the Clinic (QUANTEC) review has been published in the International Journal of Radiation Oncology*Biology*Physics, the official journal of the American Society for Radiation Oncology (ASTRO) to update recommendations for the safe irradiation of 16 organs. For each organ, the relationship between dose/volume and clinical outcome is reviewed. These reviews replace initial recommendations published in 1991.

Industrial-grade talc exposure and the risk of mesothelioma.

Industrial-grade talc exposure and the risk of mesothelioma.

Crit Rev Toxicol. 2010 Mar 15;

Authors: Price B

Industrial-grade talc deposits are complex mixtures of mineral particles and may vary substantially in composition across small geographical areas. Typical industrial-grade talc includes amphibole cleavage fragments, platy talc, serpentine minerals, talc in fibrous form, and a minor presence of transitional fibers. Industrial-grade talc was erroneously determined to be an asbestos-containing material due to an unintended consequence of Occupational Health and Safety Administration's (OSHA's) method for measuring airborne asbestos mandated in 1972. This error was repeated, most notably, by the National Institute for Occupational Safety and Health (NIOSH) in, 1980 for talc mined in northern New York State (NYS) by RT Vanderbilt Company (RTV). Subsequent exposure studies of northern NYS talc conducted through the, 1980s and one study published after, 2000 relied on the conclusion that talc was an asbestos-containing material to infer a causal relationship between talc and mesothelioma. The present review included (1) publications concerning talc's cancer-causing potential issued by organizations concerned with occupational and public health; (2) talc exposure studies and animal and cellular studies of RTV talc; (3) mesothelioma rates in northern NYS; and (4) mesothelioma mortality among RTV mining employees. The review indicated that failure to correctly identify the mineral characteristics of talc resulted in misleading reports concerning the carcinogenic potential of talc. However, the collective data from animal and cellular studies, mesothelioma rates in northern NYS, exposure studies, and a mortality analysis of RTV mining employees do not support a causal relationship between RTV talc and mesothelioma. This conclusion is applicable to all mineral components in RTV talc and to other industrial-grade talcs and mineral aggregates with the same components.
