Researchers find 24 species believed new to science in Suriname rainforest

...ks, making conservation of the Amazon rainforest a crucial strategy for minimizing climate change. The burgeoning global carbon market creates new economic value for carbon stored in standing rainforest, providing fresh incentive for developing nations such as Suriname to avoid deforestation....

Modeling the restless brain

...suggests that this very pattern of connectivity is crucial to generating and shaping brain activity in the resting and active brain. Empirical work on the human brain is challenging due to the fact that the brain's intricacies cannot simply be manipulated and observed. Sporns and Honey compare studying t...

A new plant-bacterial symbiotic mechanism promising for crop applications

... improve crop yields of leguminous plants that are crucial for human diet (soybean, peas, ground nuts and so on…) and as animal feed (alfalfa, clover, sainfoin). In addition, cultivation of legumes living in symbiotic association with bacteria can contribute to vegetation regeneration schemes on soils depl...

New bacterium discovered -- related to cause of trench fever

...hler considers the on-going research and discovery crucial to treating patients and preventing disease. “When a patient has a high and persistent fever, we need to come up with the correct diagnosis and treatment as soon as possible – particularly for those with a weakened immune system, who can die from ...

Stroke study sheds light on left-right brain divide

...This type of “self-monitoring” function may play a crucial role in many day to day situations. For example, when preparing a meal we often have to keep track of several tasks at once and make sure we perform each one correctly and at the right time.’...

U-M researchers discover gene switched off in cancer can be turned on

...ential target to treat lung cancer is particularly crucial as the death rate from lung cancer has not changed in 30 years. Newer treatments are much less toxic and extend lives by months, but the same people who died from lung cancer 30 years ago, would still succumb to this disease today. Targeted therap...

Physicist cracks women's random but always lucky choice of X chromosome

...ce one of those two X chromosomes. This process is crucial to survival and problems with the process are related to serious genetic diseases. Both X chromosomes in a cell have a suicide gene called XIST which, if activated, seals the chromosome behind a barrier of RNA preventing the activation of any othe...

New findings challenge established views on human genome

...sive catalog of all components of the human genome crucial for biological function. “This impressive effort has uncovered many exciting surprises and blazed the way for future efforts to explore the functional landscape of the entire human genome,” said NHGRI Director Francis S. Collins, M.D., Ph.D. “Bec...

Bacteria ferry nanoparticles into cells for early diagnosis, treatment

... cargo dislodges from the bacteria, which are both crucial steps in delivering this cargo," Akin said. The nanoparticles, which range in size from 40 to 200 nanometers - or billionths of a meter - are attached to the bacteria with "linker molecules." "The use of commercially available polystyrene nanop...

454 sequencing identifies HIV drug resistance at early stage

...454 Sequencing to detect rare viral mutations is a crucial research tool to better understand the early stages of HIV drug resistance.” It is estimated that 22 million people have died from AIDS and over 42 million people are living with HIV/AIDS worldwide. In the U.S. alone, 40,000 new infections occur e...

Exploring the dark matter of the genome

...me, the centromere is the knot. Centromeres play a crucial role in controlling chromosome duplication during ...re of the sequence of heterochromatin is clearly a crucial step toward a better understanding of genome functions. Karpen notes that one intensively studi...

Fat fish put obesity on the hook

...inishing the fat-storing mechanisms that were once crucial to the survival of our species. The zebrafish has become a model animal for the study of many diseases because it has a backbone and because its genetics have been well described. This is one more example of how basic experimental biology – zoology p...

Reconstructing the biology of extinct species: A new approach

...ng a stable image of the environment is especially crucial for acrobatic animals that leap, glide, or fly. To make the discovery, the scientists scanned skull samples of each species, measuring the size of each semicircular canal and calculating the radius of curvature. Most of the specimens were scanne...

Experts predict Tamiflu could halve the pandemic influenza death toll versus no intervention

...making prophylaxis and treatment with antivirals a crucial part in the efforts to reduce the burden of pandemic influenza.4 “In an environment full of uncertainties, it is best to have a comprehensive plan in place,” said Arnold Monto, professor of epidemiology and influenza expert at the University of M...

Treating HIV in war zones -- Public health emergencies need rapid advice from WHO

...tion for disruption," say the authors. Some of the crucial contingency measures include: Providing patients with extra emergency drug supplies that can be taken in case of program interruption. Stockpiling emergency supplies of ART and securing them against vandals and looters Distributing clinic...

First confirmed common genetic risk factors for breast cancer

...udy report that these five genes code for proteins crucial to biological activities that previously had not been implicated as triggers of breast cancer. The genes carry the DNA recipes for proteins important to the growth and duplication of body cells and the signalling, or communications, that must occur ...

Cytomegalovirus exacerbates atherosclerosis through an autoimmune mechanism

...upport the hypothesis that virus infection plays a crucial role in mediating the atherosclerotic process. Moreover, these findings contribute to the design of novel preventive and therapeutic strategies....

Common treatment for methamphetamine overdose may damage brain cells

...ospital, who was not affiliated with the study. "A crucial next step is to determine how atypical antipsychotic medications would affect methamphetamine toxicity in the same model." The rats in the experiment were injected with either methamphetamine or a saline solution over a period of eight hours. When...
