While rovers and orbiting spacecraft scour Mars searching for clues to its past, researchers have uncovered another piece of the red planet in the most inhospitable place on Earth — Antarctica.

The new specimen was found by a field party from the U.S. Antarctic Search for Meteorites program (ANSMET) on Dec. 15, 2003, on an ice field in the Miller Range of the Transantarctic Mountains, roughly 750 kilometers from the South Pole. This 715.2-gram black rock, officially designated MIL 03346, w

A review article by Yale researchers reaffirms that the vast majority of people with cardiovascular disease can travel safely on airlines, provided they follow basic guidelines such as carrying an ample supply of medication or waiting two weeks to travel after having a cardiac procedure.

Published in the July 20 issue of Annals of Internal Medicine, the article reviewed previous studies on air travel and cardiovascular disease. “We pulled together work that has been done on the topic, syn

Researchers from the Universitat Autònoma de Barcelona have developed the first international server that allows the user to analyze genetic diversity on a large scale. The web service, published in the special edition of Nucleic Acids Research on bioinformatics, will facilitate research about the genetic basis of hereditary diseases. The server is called PDA (Pipeline Diversity Analysis) and for the first time biologists around the world can search for small variations in the genomes of different

The exploration of near-Earth space will enter a new phase on 26 July when a spacecraft called Tan Ce 2 (Explorer 2) lifts off from Taiyuan spaceport, west of Beijing, on a Chinese Long March 2C rocket. The launch is currently scheduled to take place at 08:23 BST (07:23 GMT).

Tan Ce 2 is the second spacecraft to be built for the Double Star programme, a unique collaboration between Chinese and European scientists. Its predecessor, Tan Ce 1 (Explorer 1), was successfully launched on a sim

Autoimmune diseases are quite complex and this is due to the fact that these illnesses do not depend on just one gene. Thus, in order to find a suitable treatment, it is not enough to identify a gene involved in the development of the disease – each and every one has to be identified. To this end, a number of strategies have been design; for example, many geneticists have begun to analyse the genetic differences between healthy individuals and ill ones. A team at the Leioa campus of the University

Researchers seeking to direct cancer-killing immune cells against the deadliest brain tumors have three new targets that show promise in laboratory studies and in a Phase I patient trial, according to two articles in the July 15 issue of the journal Cancer Research.

The antigens, previously associated with several other types of cancer cells, were recently found to be expressed in the most common and aggressive type of malignant brain tumor, glioblastoma multiforme (GBM). Scientists at Ce
