An herbal extract inhibits the development of pancreatic cancer

(PHILADELPHIA) An herb recently found to kill pancreatic cancer cells also appears to inhibit development of pancreatic cancer as a result of its anti-inflammatory properties, according to researchers from the Kimmel Cancer Center at Jefferson. The data were presented at the AACR 100th Annual Meeting 2009 in Denver. (Abstract #494)

Moon dust hazard influenced by Sun's elevation

In the 1960s and 1970s, the Apollo Moon Program struggled with a minuscule, yet formidable enemy: sticky lunar dust. Four decades later, a new study reveals that forces compelling lunar dust to cling to surfaces — ruining scientific experiments and endangering astronauts' health —change during the lunar day with the elevation of the sun.

Increasing carbon dioxide and decreasing oxygen make it harder for deep-sea animals to breathe

MOSS LANDING, CA — New calculations made by marine chemists from the Monterey Bay Aquarium Research Institute (MBARI) suggest that low-oxygen "dead zones" in the ocean could expand significantly over the next century. These predictions are based on the fact that, as more and more carbon dioxide dissolves from the atmosphere into the ocean, marine animals will need more oxygen to survive.

New study warns damage to forests from climate change could cost the planet its major keeper of greenhouse gases

New York (17 April 2009) –The critical role of forests as massive "sinks" for absorbing greenhouse gases is "at risk of being lost entirely" to climate change-induced environmental stresses that threaten to damage and even decimate forests worldwide, according to a new report released today. The report will be formally presented at the next session of the United Nations Forum on Forests (UNFF) taking place 20 April-1 May 2009 at the UN Headquarters in New York City.
