New treatment for severe malaria

...have been able to treat severe malaria in rats and primates effectively; it now remains to be seen whether these results can be replicated in people. "There's often a lack of ability to treat people suffering from severe malaria," says Professor Wahlgren. "We've developed a substance that might be able to h...

Scientists describe new African monkey genus ?first in 83 years

...e primate collection to compare Kipunji with other primates and found that the skull and external features of the specimen do not exhibit the diagnostic morphological features of baboons: namely, a long rostrum or deep depressions on the outside of the lower jaw. Also, depressions under the orbits of the Kip...

Parallel evolution: Proteins do it, too

...reatic enzyme that breaks down bacterial RNA. Most primates have one gene encoding the enzyme, but he found that the douc langur, a colobine from Asia, has two---one encodes RNASE1, and its duplicate encodes a new enzyme, RNASE1B. The duplicate enzyme, it turns out, works better than the original in the acidi...

Gorilla susceptibility to Ebola virus: the cost of sociality

...hed light on the evolutionary costs experienced by primates living in groups. The authors note that thousands of gorillas have probably disappeared as a result of the Ebola outbreak studied here, and they point out that because the impact of Ebola on apes is still difficult to control, strengthened protection...

Study shows frogs can play key role in stem cell research

...ntil now, stem cells have been obtained from mice, primates and humans, but never from amphibians. But, because the African clawed frog is easier to study than mice and humans, the Edinburgh team anticipate that it will become an important research tool in their quest to understand and, ultimately, treat dise...

HIV-1's high virulence might be an accident of evolution

...ny species of monkeys, naturally infected nonhuman primates usually don't suffer the symptoms associated with AIDS. The evidence now revealed by an international team of researchers is the first to offer an explanation for this striking difference. The group found that a viral protein earlier shown to help t...

Chimpanzee study reveals genome variation hotspots

...ortance of studying the genetic variation in other primates to understand our own genome better, but it can also shed light on the diversity and adaptations of our nearest relatives," says Stone, who is one of the study's senior co-authors, along with Charles Lee, an assistant professor in the Department of P...

Successful transplantation from pig embryos to mice

...s to transplant such animal tissues into non-human primates have evoked a fierce immune response. However, embryonic tissues, such as those from pigs (in which the insulin-producing cells are similar to those of humans), might not be rejected as strongly. New research by Prof. Yair Reisner of the Weizmann Ins...

Primates take weather into account when searching for fruits

...dings reported this week reveal that at least some primates can use their stored knowledge of recent weather as a tool for guiding their foraging behavior when searching for ripening fruit. The work, which potentially informs our understanding of how cognitive skills developed in humans and other primates, is...

First surveys of Tanzanian mountains reveal 160+ animal species, including new & endemic

Some people believe "bush baby" refers to the animal's cries which can sound similar to the cries of human babies. In one small valley, Nike Doggart of the Tanzania Forest Conservation Group disco...

The findings could serve as the basis for a new approach to quickly develop virus-specific therapies for known, em...

The primates chosen for this "index species" effort are rhesus macacque (Macaca mulatta), marmoset (Callithrix jacchus) and orangutan (Pongo pygmaeus). In the future, NHGRI intends to add other organisms to the list of index species for which high-density genome ...
