Editor : Pictures, video and sound of this rare monkey are available on the Saving Wildlife website.

Researchers from the Wildlife Conservation Society, working in conjunction with other partners, have discovered Africa’s first new species of monkey in over 20 years, marking the third monkey WCS scientists have found in the last six months. The new species is described in the current issue of Science.

The latest find is named the “Highland Mangabey” (Lophocebus kipunji), a long-haired forest primate first discovered on the flanks of the 10,000 ft (2961 m) volcano Mt. Rungwe and in the adjoining Kitulo National Park. Last December, WCS researchers found a new species of macaque in India, followed by a new variety of titi monkey in Bolivia.

First, nanotechnology researchers at Cornell University built a device so sensitive it could detect the mass of a single bacterium--about 665 femtograms. Then they built one that could sense the presence of a single virus -- about 1.5 femtograms. Now, with a refined technique, they have detected a single DNA molecule, weighing in at 995,000 Daltons -- a shade more than 1 attogram -- and can even count the number of DNA molecules attached to a single receptor by noting the difference in mass.

The devices, which fall in the class of nanoelectromechanical systems (NEMS), could be made even more sensitive through increased miniaturization, the researchers say.

A study in the May 20 issue of Science holds mixed blessings for scientists who follow research in gene therapy and stem cell biology. The study, conducted by scientists from Cincinnati Children's Hospital Medical Center, and Hannover Medical School and Hamburg University in Germany, reveals important evidence that tells us more about how blood forming stem cells regenerate. On the other hand, scientists offer caution in regards to the side effects associated with genetic engineering of stem cells.

Scientists have isolated the first human embryonic stem cell lines specifically tailored to match the nuclear DNA of patients, both males and females of various ages, suffering from disease or spinal cord injury.

The research is being released by the journal Science, which is published by AAAS, the non-profit science society, on the Science Express website on 19 May, 2005.

Currently, the PDB contains approximately 29,000 protein structures comprising over 70,000 experimentally determined three-dimensional structures of over 5,000 different low molecular weight compounds. Information about these PDB ligands can be very helpful in the field of molecular modelling and prediction, particularly for the prediction of protein binding sites and function.

With locusts and drought having destroyed crops and stripped grazing land for six million people across West Africa, small farmers have started selling livestock cheaply and eating the seed corn they should plant during next month's expected rains, the United Nations Office for the Coordination of Humanitarian Affairs (OCHA) said today.

In this obesity-obsessed world, the dream ingredient must be something that tastes good enough to be a condiment or flavoring and yet somehow helps us keep our weight down. Consider hydroxycitric acid (HCA), known variously as Brindle berry or Malabar tamarind, which is used in Indian and Thai food as a condiment and flavoring agent.
