Paclitaxel combination improves survival from small-cell lung cancer
Combining paclitaxel (Taxol) with two other chemotherapy drugs appears to improve survival in patients with small-cell lung cancer (SCLC) compared with a standard regimen without paclitaxel, according to results from a randomized clinical trial in the August 6 issue of the Journal of the National Cancer Institute.

Cervical cancer vaccine may lose effectiveness during ovulation
A new study has found that a vaccine against human papillomavirus 16 (HPV16), the virus that causes cervical cancer, produces antibodies against HPV16 at the site where cervical cancer develops--a promising indication of the vaccine's effectiveness.

This is clearly Europe's time for interplanetary exploration. Having sent the first European mission to Mars, ESA is about to launch its first probe to the Moon.

Is erosion helping Himalayas to grow?
Lehigh University professors Peter Zeitler and Anne Meltzer, leading their second international research expedition in the Himalayas, believe the Indus and Tsangpo Rivers are eroding gorges so deep that they are weakening the earth's crust, encouraging an upward surge of hot metamorphic and mountain-forming rock.
