Nicotine rush hinges on sugar in neurons

...low signals to pass between neurons. The results reveal an important role for the sugar molecules in such proteins. “Our studies fill a major gap in the field and set a new paradigm,” said Lin Chen, associate professor of molecular and computational biology at USC. Many existing theories, which do not...

Cellular message movement captured on video

...e-lapse images of a bovine aortic endothelial cell reveal the motion toward the cell's nucleus of a message-...scope slides. Those snapshots of fixed cells can’t reveal paxillin movement. “We can now see the dynamics of how paxillin and other proteins move inside th...

New study finds genetically engineered crops could play a role in sustainable agriculture

...alth and biodiversity, but few analyses exist that reveal the actual effects genetically modified plants have on other non-modified species. In an analysis of 42 field experiments, scientists found that this particular modification, which causes the plant to produce an insecticide internally, can have an e...

Salty oceans provide early warning for climate change

...y realising that salt is the key. Their results reveal that a build up of salty water can stimulate deep water circulation, while a diluting of the waters is linked to sluggish flow. “Salt plays a far more important role that we first thought,” says Professor Rainer Zahn, a palaeoclimatologist at the Aut...

Researchers examine carbon capture and storage to combat global warming

...thorough technical understanding of the risks will reveal best practices, the scientists also stressed the need for good management to see that proper procedures are followed. Benson points to a familiar technology as a model for thinking about and tackling risk. ''People often ask, is geological stor...

Massive herds of animals found to still exist in Southern Sudan

...ve that follow-up aerial surveys and tracking will reveal that the team missed a significant portion of kob due to the animals’ movements during the surveys. As a result, they believe that there could actually be well over a million white-eared kob in Southern Sudan. Combined with the tiang and Mongalla gaz...

New findings challenge established views on human genome

...ore than 600 million data points. “Our results reveal important principles about the organization of functional elements in the human genome, providing new perspectives on everything from DNA transcription to mammalian evolution. In particular, we gained significant insight into DNA sequences that do no...

Exploring the dark matter of the genome

...ience. The annotated heterochromatic sequences reveal over 200 protein-coding genes. The heterochromatin also includes other features of biological importance, including sequences that code for non-protein-coding RNAs and other functional elements, such as small RNAs that neutralize transposable element...

The kapok connection -- Study explains rainforest similarities

...cess. When the seed pods ripen, they break open to reveal fluffy fibers that are used to stuff pillows and mattresses. The seeds, which are about the size of a sunflower seed, are buoyant and able to float down rivers along which the colossal trees grow. Dick and colleagues investigated which of several ...

Weizmann Institute scientists develop a general 'control switch' for protein activity

...function of numerous proteins is still unknown. To reveal this function, scientists perform various genetic manipulations to increase or, conversely, decrease the production of a certain protein, but existing manipulations of this sort are complicated and do not fully meet the researchers’ needs. Prof. Mor...

'Smart' mice teach scientists about learning process, brain disorders

...line edition of the journal Nature Neuroscience , reveal a new mechanism of learning in the brain, which might serve in humans as a target for treating disorders such as post-traumatic stress disorder, Alzheimer’s disease or drug addiction, the researchers said. "It’s pretty rare that you make mice ‘sma...

Better insight into brain anatomical structures

...plexes currently used as MRI contrast agent cannot reveal anatomic structures. As reported in the journal Angewandte Chemie, Korean researchers led by Jung Hee Lee at Samsung Medical Center and Taeghwan Hyeon at Seoul National University have now developed a new MRI contrast agent using manganese oxide nano...

Catching cancer's spread by watching hemoglobin

...an map out the distribution of red blood cells and reveal the vessels themselves. If the imaging is fast enough, researchers can capture snapshots of blood flow in individual vessels. Moving beyond mere imaging, the technique can detect the difference between oxygen-carrying hemoglobin (oxyhemoglobin) and o...

pHLIP, a novel technology to locate and treat tumors

... said, “We believe that universal medical tests to reveal many health problems at earlier stages may be developed based on pHLIP technology? “Our discovery is an example of the reason that the NIH and DOD support basic science—we were working on the principles of membrane protein folding, and made a disc...

Invasion of the island bats

As the culmination in the study of several independent bat groups, this article shows ...

Genome of yellow fever/dengue fever mosquito sequenced

...action, to help us understand mosquito biology and reveal new ways to interfere with disease transmission," Tu said. According to the article in Science Express, the general failure to date of conventional disease prevention strategies for most mosquito-borne pathogens provides a strong incentive to expl...

In Iran, cheetahs collared for the first time

...hs use to travel between protected areas, and will reveal the key features in the landscapes that are critical to their survival. . "This is an amazing milestone in securing the long-term future for the Asiatic cheetah," said Wildlife Conservation Society biologist Dr. Luke Hunter, who led the internatio...

Natural antibiotics yield secrets to atom-level imaging technique

...ct a detailed image of a peptide or protein and to reveal how it sits in the cell membrane," providing clues for modifications that might make synthetic AMPs even more effective in overcoming ever-increasing bacterial resistance. For instance, rearranging parts of the molecule might make it fit into the mem...

Genetic fingerprints identify brain tumors' origins

Genetic fingerprints that reveal where a brain cell came from remain distinct even after the cell becomes a brain tumor, an international coalition of scientists will report in the February 1 issue of Cancer Research. The finding adds a new layer of complexity to the quest to unde...
