Lessons from the orangutans: Upright walking may have begun in the trees

...u can learn about effects that living in logged or degraded habitat would have on their locomotion. These could affect energy levels, for example, if they have to go to the ground, which is incredibly risky because the Sumatran tiger is down there licking its lips. The Sumatran orangutan population is predict...

Motor protein plays key role in connecting neurons

...es. The rapidly moving protein is easily degraded and needs tight regulation. "If you don't want to ...is cut and plans to examine whether the protein is degraded in spinal cord injuries. "We already have evidence that if this protein degrades, most frequently wi...

An AIDS-related virus tricks cells to become tumors, new Penn study finds

...otein called hypoxia-induced factor 1a (HIF-1a) is degraded through ubiquitylation before it can start the process of activating genes responsible for inducing growth of more blood vessels to supply the tumor with oxygen. However, in a KSHV-infected cell, p53 and VHL themselves would be targeted for degradati...

How nature tinkers with the cellular clock

...e cell cycle machinery are produced, activated and degraded to make sure that the schedule is kept. These layers of control work differently and are usually studied separately, but researchers at the European Molecular Biology Laboratory (EMBL) and the Technical University of Denmark (DTU) have now discovered...

Global warming may warrant new approaches to ecosystem restoration

...n, including reafforestation and rehabilitation of degraded land, may be a common response to the effects of climate change, but the implications of this changing environment must be considered. Using past ecosystem conditions as targets and references may be ineffective under new conditions. In addition, ...

Study reveals how cells destroy faulty proteins in cystic fibrosis

...itinated proteins, including faulty CFTR, are then degraded or shredded by the proteasome," Cyr said. "Understanding this pathway gives us greater insight into what's wrong with the protein -- information that will help people design better therapeutics for the disease," Cyr said. ...

Stanford snake venom study shows that certain cells may eliminate poison

...ey released the expected proteins and the proteins degraded the sarafotoxin 6b. Mast cells also enhanced resistance of mice to sarafotoxin 6b when it was injected in vivo. Next, Galli and Metz did experiments using the whole venom, not just the isolated toxin. Some of the mice they worked with were genetica...

Inside rocks, implications for finding life on Mars

...arp and crisp. So, we can see how the fossils have degraded over millions of years, and learn what are real biological features and what has been changed over time." His research is published in the January issue of the journal Astrobiology, in which he reports confocal microscopy results of the ancient foss...

World Trade Center identifications pushed forensic DNA technology

...mingled, that fire and water at the site had badly degraded many specimens, and that, as time progressed, the ...g are replaceable, it quickly became apparent that degraded DNA made the use of STR by itself impossible in many victim identifications. Shaler and colleague...

The Amazon in 2050: Implementing the law could save a million square kilometers of rainforest

...est ecosystems and entire watersheds will be badly degraded over the next 45 years if we don't rapidly increase our capacity to govern this dynamic region. By developing the first empirically-based, policy sensitive model of Amazon deforestation to assess forest losses within major watersheds, eco-regions, v...

GPSDB, the free Gene and Protein Synonyms DataBase

...n River region, not only teaches us how to restore degraded soils, triple crop yields and support a wide array of crops in regions with agriculturally poor soils, but also can lead to technologies to sequester carbon in soil and prevent critical changes in world climate," said Johannes Lehmann, assistant prof...

Amazonian terra preta can transform poor soil into fertile

...n River region, not only teaches us how to restore degraded soils, triple crop yields and support a wide array of crops in regions with agriculturally poor soils, but also can lead to technologies to sequester carbon in soil and prevent critical changes in world climate," said Johannes Lehmann, assistant prof...

Common bacteria pirate natural mechanism to get inside cells

...ither stay inside the newly created vesicle and be degraded or resurface to be activated once again. Bacteria and viruses also want inside cells and out of the direct line of fire of the immune system or treatments such as antibiotics for bacterial infections, Dr. Daaka says. "Some bacteria and viruses bind ...

Plants give pests sock in the gut

...ts had fallen significantly. "If the IIM is being degraded by the enzyme, pieces of it should not appear in the fecal pellets of the insect," notes the Penn State researcher. When used in conjunction with the Bt-toxin, a low dose of Mir1-CP was able to achieve a very high mortality rate in the insects, as w...

Embryos tell story of Earth's earliest animals

...t the membrane, or with a broken membrane, embryos degraded quickly. Likewise, soft-bodied larvae that hatch from the egg-like fertilization envelope did not fossilize, even under reducing conditions. The scientists predict early animal fossils from 500 million years ago will be embryos encased in the ferti...

WWF peeks into mysterious life of Borneo's pygmy elephants

...t into palm oil plantations being higher along the degraded forest-plantation areas. The Sabah Wildlife Department described the study as very important and the results could be used to assist the department in preparing Sabah's elephant conservation plan. The pygmy elephants were determined by WWF in 200...

Overfishing may drive endangered seabird to rely upon lower quality food

...their nesting habitat, they're also experiencing a degraded prey environment." The researchers pointed out that the U.S. Fish and Wildlife Service has recently decided to start the process to remove the marbled murrelet from the Endangered Species list, denying it protection even though the bird has not reco...

Discovering the first steps in transcription-coupled repair

...els have assumed that the stalled RNAPII has to be degraded and moved out of the way so the lesion can be repaired, after which transcription of the gene must start over with a new RNAPII. Other possibilities are that the original RNAPII is somehow made to start up again, bypassing the lesion, or that the RN...

New book highlights world's borderless conservation areas

...opulations if these areas of rich biodiversity are degraded or lost." The title, "Transboundary Conservation," defines the new terminology for international efforts to protect ecosystems in their entirety. From the first transboundary protected area established in 1932, when Montana's Glacier National Park w...
