Massive herds of animals found to still exist in Southern Sudan

...ecords of elephants in Sudan. “Although we were telling people that wildlife was still present in Southern Sudan, nobody believed us,” said Maj. Gen. Alfred Akwoch, undersecretary of the Ministry of the Environment, Wildlife Conservation, and Tourism. “Thanks to the aerial surveys, we now know that wildli...

Runners -- Let thirst be your guide

...el of zero, but when you’re exercising, the AVP is telling your kidney to excrete a volume of fluid that is markedly less than the maximum the kidney can excrete at rest,” Verbalis says. Too much water intake in an endurance exerciser whose AVP levels are on the rise means that some of the ingested water wil...

Study of protein folds offers insight into metabolic evolution

...e recent protein architectures. "This mosaic is telling you that the new enzymes and old enzymes are together performing side by side," Caetano-Anollés said. "In some cases in the same protein you have old domains and new domains working together." This finding supports the hypothesis that protein arch...

Type of stem cell found to reside in transplanted lungs

...e connective tissue cell types. One of the most telling findings was that, in cases where the transplant donor and recipient were not of the same sex, nearly all the MSCs (about 97 percent) originated in the donor, indicating that they were present in the tissue since the time of transplantation. "We were...

Cancer-killing invention also harvests stem cells

...delivers an apoptosis signal, a biochemical way of telling the cancer cell to kill itself. Within two days, that cancer cell is dead. Normal cells are left totally unharmed because the device selectively targets cancer cells. The apoptosis signal is delivered by a molecule called TRAIL that coats the c...

Racing neurons control whether we stop or go

HIV protein enlisted to help kill cancer cells

...their DNA," Hawkins says. "This results in signals telling cancer cells to die, but the cells don't quite have the permission they need to do it. Proteins like TAT-Bim can tip the balance in favor of death." To further enhance the cancer-killing power of TAT-Bim and similar proteins under development, Hawk...

Heavy smoking cuts women's chance of pregnancy -- even with donated oocytes

...y not the last, but it means that we should now be telling patients, if they are heavy smokers, that even if fertilisation takes place they have less chance of achieving a successful pregnancy, whether they are trying to conceive naturally, or through IVF, and particularly with donated ooctyes. Furthermore, ...

Train your brain to hear your friends at a party

...nk it is actively sending messages back to the ear telling it how to cope with the new hearing loss, perhaps by stimulating or increasing the signal which is being blocked. It's compensating for the problem in a really clever way." Irving is trying to locate the place in the brain which is channeling thes...

Memories: It's all in the packaging, scientists say

...eurological basis for what psychologists have been telling us for years," said Michael Rugg, director of UCI's Center for the Neurobiology of Learning and Memory and senior author of the paper. "You can't get out of memory what you didn't put into it. It is not possible to remember things later if you didn't...

Need to pull an all-nighter?

...surprise in the research was that the main message telling the brain to go to sleep probably does not come from neurons, but from neighboring glial cells, which appear to produce the greatest amounts of nitric oxide. Until recently, glial cells have been assumed to play only a supportive role in the brain. R...

From a lowly yeast, researchers divine a clue to human disease

... Normally, Sen1 acts like a molecular stop sign, telling another protein called RNA polymerase II when to stop transcribing genetic information from DNA into related threads of RNA. The polymerase reads along DNA strands, building RNA as it goes. Multiple genes strung along a single length of DNA are sep...

New research to cut animal testing

...developed at Gentronix has proven very reliable at telling us whether a drug will cause cancer but some chemicals, called promutagens, only become carcinogenic once they have passed through the body's liver. "This grant will help us develop new non-animal experiments to identify these other toxic compound...

A giant among minnows: Giant danio can keep growing

...al to special cells attached to the muscle fibers, telling these cells to grow and join to adjacent muscle fiber to repair the injury. There is also an application to fish farming. “If we understood how fish grow, we could figure out strategies for enhancing the growth of farmed fish such as Atlantic salmo...

Herzog and Aton recorded neuron activity from the SCN using a multielectrode array with 60 electrodes upon which they place S...

Trotting with emus to walk with dinosaurs

...logy. The bigger picture is also important and telling at the Red Gulch Dinosaur Tracksite, said Breitaupt. For instance, it appears that the dinosaurs were traveling along a tidal flat, perhaps in family groups, since there are juvenile and adult tracks. If so, that could infer some sort of parental car...

When it comes to gene transcription, random pauses aren’t quite so random, study finds

...ming hairpins. "That's great," Block said. "It's telling us that the enzyme is doing just what it should. After all, it's seen the same sequence eight times in a row, so it had better do the same thing eight times in a row. It also paused at several other sites as well, which is interesting. Sometimes it p...
