The making and breaking of microtubules

...rotofilamentary ribbons immediately straighten and convert to normal microtubules, suggesting that the ribbons and gently curved sheets correspond to the polymerizing protofilaments at the end of a growing microtubule. Making contacts: In 1998, when she was a postdoctoral fellow in the laboratory of Kennet...

Anammox bacteria produce nitrogen gas in oceans' snackbar

...en loss results from the activity of bacteria that convert nitrate (via nitrite) with organic matter to nitro...ed that anammox bacteria can use organic matter to convert nitrate into nitrite (much better than denitrifying bacteria). This new finding even increases the i...

Genetic defects give the immune system the green light to attack the pancreas

...n. Without this crucial hormone, their body cannot convert food into energy. To sustain life, they must get insulin through injections. The disorder can emerge in childhood, adolescence and even appear in adulthood, but the genetic stage is set beforehand. T-cells play a key role. They are part of the highl...

NASA study finds snow melt causes large ocean plant blooms

...teria called denitrifying bacteria. These bacteria convert a nitrogen-based nutrient readily consumable by plants in seawater, called nitrate, into forms of nitrogen that most plants cannot use. One form of nitrogen that plants cannot consume is nitrous oxide, also known as laughing gas. In the atmosphere, ...

Microbial fuel cell: High yield hydrogen source and wastewater cleaner

...act that bacteria, without a power boost, can only convert carbohydrates to a limited amount of hydrogen and ...-- they can leap over the fermentation barrier and convert a "dead end" fermentation product, acetic acid, into carbon dioxide and hydrogen. Logan notes, "Bas...

Transgenic plants remove more selenium from polluted soil than wild plants, new tests show

...(APS). The enzyme is key to the plant's ability to convert selenate into a non-toxic form of selenium, allowing the plant to accumulate more of the contaminant without incurring harm. In the field trial, the APS plant line absorbed 4.3 times more selenium than the wild-type plants. The other two transgenic ...

Tiny scaffolding allows stem cells to become working fat cells

...and play a role in insulins ability to effectively convert glucose into energy. "If we could learn how to control fat formation in the body, then we could keep people leaner, lowering their chances of becoming insulin-dependent, and lowering the likelihood they would develop type II diabetes," Kniss said. ...

Wisconsin scientists grow critical nerve cells

...es in the body. But researchers have struggled to convert blank-slate embryonic stem cells into motor neurons, says Zhang. The goal proved elusive even in simpler vertebrates such as mice, whose embryonic stem cells have been available to scientists for decades. One reason scientists have had difficulty ma...
