Massive herds of animals found to still exist in Southern Sudan

... the richest in Africa. The plan would include the integration of several thousand ex-combatants from the Sudan People’s Liberation Army into wildlife services, help establish and manage official networks of national parks and other protected areas and integrate conservation principles into the management of lan...

New findings challenge established views on human genome

...in Hinxton, England, who led ENCODE’s massive data integration and analysis effort. The ENCODE consortium’s major findings include the discovery that the majority of DNA in the human genome is transcribed into functional molecules, called RNA, and that these transcripts extensively overlap one another. This ...

Human stem cell treatment restores motor function in paralyzed rats

...once treated. “Physical therapy may accelerate integration of the grafted stem cells and enhance their therapeutic benefit,” Johe said, adding that the goal is to provide a significant gain in functional mobility of the patient’s legs. This study builds on Marsala’s previous work in rat models using human...

In young mice, gregariousness seems to reside in the genes

...lation. The social life of these animals is a rich integration of behavior, vocalizations and positive emotional experience." The level of social interplay of the two strains of mice, Panksepp and Lahvis note, is mirrored in their vocalizations, and the differences in vocalization between the two types of mou...

Wired for sound: How the brain senses visual illusions

...chool of Medicine have found new evidence of rapid integration of auditory and visual sensations in the brain. T... findings by scientists in the field that show how integration of multiple sensations can happen much more rapidly than we thought before," said Mishra. "We show ...

Erectile dysfunction in diabetes is due to selective defect in the brain

...PVN) of the hypothalamus, located in the brain, an integration center between the central and peripheral nervous systems. The site is involved in numerous functions, including erectile function and sexual behavior, and is a primary site within the forebrain that has been implicated in penile erection. The invest...

Do you hear what i see?

...o could be used to reveal the role of audio-visual integration in communication or to help pin down where sounds are coming from. "Clearly, our acoustical understanding often improves if we can see the lips of the speaker—for example at a crowded cocktail party," he says. "However, currently it is not clear whet...

DNA layer reduces risk of reserve parts being rejected

...up the attachment to bone tissue and therefore the integration of bone implants in the native bone tissue. Finally, DNA can be enriched with biologically active factors that, for example, facilitate the formation of bone tissue and blood vessels. All in all, a DNA coating could be safe, reduce the immune respons...

Genomics throws species definition in question for microbes

...sequences for all type strains to help advance the integration of genomic information into our understanding of microbial diversity and enable researchers to map phenotypes to genomes. ...

Breathing easy: When it comes to oxygen, a bug's life is full of it

End-of-life care can be improved

...ebanon, N.H., describes recent developments in the integration of palliative and critical care. Palliative and end-of-life care in the ICU is an appropriate and under-developed area for quality assessment and improvement, according to Richard Mularski, M.D., M.S.H.S., from the Veterans Affairs Greater Los Ang...

New brain-chemistry differences found in depressed women

...late, which is involved in mood regulation and the integration of sensations and emotions, women who later responded to antidepressant treatment had far lower mu-opioid responses than women who did not respond to medication. The new findings add the mu-opioid system to the list of brain systems that appear t...

One signal elicits thousands of answers

...r a variety of incoming stimuli", says Mann. "This integration of signals could be independent, with phosphorylation of each site occurring separately from the others. It could also be dependent so that a 'priming site' has to be phosphorylated first for the subsequent modification of all other sites in the prot...

Nano-devices hold promise for early-stage cancer detection

...initiative to expand existing nano-fabrication and integration facilities at McMaster to establish a world-class Micro- and Nano-Systems Laboratory for the development of miniaturized, low-cost and easy-to-use prototypes for imaging and sensing in healthcare and environmental applications. "The imaging and se...

Researchers map spread of pathogens in the human body

...rinary Science, and their teams have pioneered the integration of mathematical models with observational data to predict the spread of individual bacteria within the human body. Their findings are reported in the November issue of PLoS Biology. The work analyses the spread and distribution of Salmonella in t...

On the golf tee or pitcher's mound, brain dooms motion to inconsistency

...includes study of the neural basis of sensorimotor integration and movement control. He, postdoctoral researcher Mark Churchland and electrical engineering doctoral candidate and medical student Afsheen Afshar authored the study. It's as if each time the brain tries to solve the problem of planning how to move...

Leptin has powerful effect on reward center in the brain

...profound implications for how researchers view the integration of metabolic signals in the brain," said the senior author, Ralph DiLeone, assistant professor of psychiatry. In this study the researchers demonstrated that leptin signaling, via its receptor, occurs in the dopamine neurons in the VTA and that it...

Scientists identify protein with a crucial role in cell death

... to supplying energy, mitochondria also ensure the integration and amplification of apoptosis signaling in the cell. From the research of De Strooper and Scorrano, it turns out that PARL is a key to initiating apoptosis in the mitochondria. Although the mitochondria of the knock-out mice have a normal developmen...
