... Borneo pygmy elephants depend for their survival on forests situated on flat, low lands and in river valleys, the study found. Unfortunately, it is also the type of terrain preferred for commercial plantations.

A new mechanism to attack hard-to-treat fungal infections has been revealed by scientists from the biotech company Anacor Pharmaceuticals Inc., California, and the European Molecular Biology Laboratory (EMBL) outstation in Grenoble, France. In the current issue of Science they describe how a new compound kills fungal pathogens by blocking an enzyme crucial for their protein synthesis.... The hum...Fruit bats are not 'blind as a bat'
......... The retinas of most mammals contain two types of photoreceptor cells, the cones for daylight vision and colour vision, and the more sensitive rods for night vision. Nocturnal bats were traditionally believed to possess only rods. Now scientists at the Max Planck Institute for Brain Research in Frankfurt and at The Field Museum for Natural History in Chicago have discovered that noctur...... From 2 p.m. to 4 p.m. CDT on Thursday, May 31, a program at BCM will feature more in-depth discussions on the science, clinical significance and ethical implications of the project.

The wild tiger now occupies a mere 7 percent of its historic range, and the area known to be inhabited by tigers has declined by 41 percent over the past decade, according to an article published in the June 2007 issue of BioScience. Growing trade in folk medicines made from tiger parts and tiger skins, along with habitat loss and fragmentation, is believed to be the chief reason for the losses....Nobel laureate James Watson receives personal genome in ceremony at Baylor College of Medicine

It is well known that human speech can provide listeners with simultaneous information about a person's emotions and objects in the environment. Past research has shown that animal vocalizations can do the same, but little is known about the development of the features that encode such information.

It was until now believed that nocturnally migrating songbirds, while venturing into the unfamiliar night sky for accomplishing their long, challenging trans-continental migrations, could at least release anti-predator vigilance thanks to the concealment of darkness.

Is the world basically good or basically bad? It appears that in the natural world the answer is "basically good."
