Computer modeling reveals hidden conversations within cells

...on, immune function and cell death. Each equation takes into account a different parameter, such as how quickly a protein is synthesized, or how quickly it is degraded. The researchers chose the NF-kappaB proteins because there is a wide body of prior research that they were able to draw on to set the in...

Scientists use gene transfer technology and common virus to block neuropathic pain in animals

...oring whether rats lift their paw, and how long it takes for them to do so, scientists can measure the degree of pain the animal is feeling. One week after surgery, some of the rats received injections of the HSV vector with GAD, while control rats did not receive the vector. Rats given the transgene vect...

Study charts origins of fear

...ccur immediately after a painful event; rather, it takes time for the memory to become part of our consciousness. The initial event activates NMDA receptors - molecules on cells that receive messages and then produce specific physiological effect in the cell - which are normally quiet but triggered when th...

Water management in cells

... starts one or two minutes later. This efflux only takes place if there is a large difference between the intracellular and extracellular salt concentrations. From this the researcher concluded that the efflux of organics is a second line of defence, which is only activated if there are considerable proble...

Surgical Robot 'Scrubs In' At UNC, May Be More Precise Than Conventional Surgery

...the key to its success," Boggess added. "The robot takes us a big step beyond traditional laparoscopy. It allows us to operate more naturally, the way we do in open surgeries, but still preserve a minimally invasive approach with small incisions." As in laparoscopy, robotic surgery involves small incision...

Lactose intolerance linked to ancestral environment

...ine, a new interdisciplinary field of science that takes an evolutionary look at health, and considers why, rather than how, certain conditions or symptoms develop. Sherman, for example, recently investigated why spices are used and why morning sickness occurs. "Both appear to serve an important function ...

Brain networks change according to cognitive task

...g or rhyming judgment. "We found that one network takes different configurations depending on the goal of the task," said Tali Bitan, primary author of "Shifts of Effective Connectivity Within a Language Network during Rhyming and Spelling." A post-doctoral fellow in the department of communication scien...

Elusive salamanders have role in developing new sampling models

... three-year SERDP project, which began in January, takes advantage of some of the Department of Energy labo...of the flatwoods salamander. The habitat modeling takes into account numerous environmental and other variables and will be used to identify the relative im...

Firefly protein lets researchers monitor molecule linked to cancer

...," Piwnica-Worms says. "Establishing that normally takes 6 months and 300 mice. With our monitoring technique, Shimon did it in a 5-day period using 30 mice. That's going to lead to tremendous cost savings." Because the luciferase-based monitoring system allows monitoring in live animals, Gross could perf...

North & South American researchers find architectural abnormalities in T. cruzi ribosome

... the transmission electron microscope. A CAT scan takes readings of a single body from different angles to reconstruct its three-dimensional images, but the microscope catches hundreds of ribosomes at different angles in a single snapshot. Frank and his colleagues have developed a battery of complex mathe...

Out of sight, out of mind? Not necessarily

...viding direct evidence that unconscious processing takes place within the brain - a controversial claim that was advanced by the likes of Sigmund Freud and William James - our results suggest that multiple pathways relay visual input into the central nervous system for different types of processing," Ro sa...

Oceans turning to acid from rise in CO2

..., it could be alarming. Oceans are quite big... It takes a lot of acid to change its pH, I guess! A report issued by the Royal Society in the U.K. sounds the alarm about the world's oceans. "If CO2 from human activities continues to rise, the oceans will become so acidic by 2100 it could threaten marine ...

U-M scientists discover identifying markers for primitive blood-forming stem cells

...lassical markers work, but they are complex and it takes a high level of skill to obtain a pure sample of HSCs," Kiel says. "We showed that using just two SLAM markers gives you similar or better purity than 10 to 12 of the best classical markers combined. It reduces the skill and time required to pick out...

A 'dimmer switch' for genes

...ructure," Graves explains. "But what we discovered takes us beyond knowing the structure. Our data were about features that are not fixed in space, but that are flexible and changing." The team used a nuclear magnetic resonance, or NMR, which allows scientists to observe how the atoms of a molecule behave...

An essential regulator of body weight revealed

...for. "We thought, this is great: NPY is gone, AgRP takes over ?how simple could it be?" Palmiter said. But when scientists at Merck created mice that lacked AgRP, and then mice that lacked both NPY and AgRP, they too had normal weight and fed normally. Speculation continued as to what molecule or molecul...

Scientists unpick genetics of first 15 minutes of life

...us. "This is one of the most crucial process that takes place in sexually reproducing animals," said Dr Karr who works in the Department of Biology and Biochemistry at the University of Bath. "Sperm DNA has to undergo a complete transformation when it arrives in the egg cell so that it can properly join ...

Gene therapy works in mice to prevent blindness that strikes boys
