Soils offer new hope as carbon sink

...ising there is so much interest in a technology to create clean energy that also locks up carbon in the soil for the long term and lifts agricultural production," he said. The trials at Wollongbar have focused on the benefits of agrichar to agricultural productivity. "When applied at 10t/ha, the bioma...

Modeling the restless brain

...ing their simulations. Sporns said he wants to create a similar large-scale computer model of the human brain that will allow them to study larger networks and connectivity, once the necessary data sets of how human neural networks are structured are available. A computational model of the human bra...

Crammed with charged DNA, pressure rises inside virus

...to do mechanical work to overcome two factors that create resistance,” said Douglas Smith, an assistant professor of physics at UCSD who headed the team that published the discovery this week in the early on-line edition of Proceedings of the National Academy of Sciences. “First, the DNA must be forced to ...

Dirty snow may warm Arctic as much as greenhouse gases

...e, including soot; clouds; and land use. Humans create the majority of airborne soot through industry and fuel combustion, while forest and open-field fires account for the rest. Because of human activity, greenhouse gas levels have increased by one-third in the last two centuries. “A one-third change...

Largest synthetic gene ever built offers insights into anti-malarial drug resistance

... gene. They previously used this same technique to create and express a synthetic version of the much smaller PfCRT gene. PfMDR1 is made up of about 4,000 base pairs and its protein is particularly large, Roepe said, making the recent work much more challenging. Already, analysis of these three anti-mal...

Breakthrough developments in rheumatoid arthritis reported

...p tell the story of how the immune system works to create specific antibodies that in turn increase a person’s risk for this crippling disease. On Monday at the Federation of Clinical Immunology Services’ (FOCIS) meetings in San Diego, CA, Dr. Gregersen and his colleagues will be presenting the lab’s l...

Now, self-healing materials can mimic human skin, healing again and again

...the material could heal itself indefinitely.” To create their self-healing materials, the researchers begin by building a scaffold using a robotic deposition process called direct-write assembly. The process employs a concentrated polymeric ink, dispensed as a continuous filament, to fabricate a three-di...

Researchers examine carbon capture and storage to combat global warming

...ood pathway is to find ways to use them that don't create a problem for the climate.'' Carbon capture has the potential to reduce more than 90 percent of an individual plant's carbon emissions, said Lynn Orr, director of GCEP and professor of energy resources engineering. Stationary facilities that burn ...

Massive herds of animals found to still exist in Southern Sudan

... above the ground for 70,000 miles (112,650 km) to create an unprecedented record of human impact on the land. A survey of Southern Sudan was part of the initial planning for the trip, but Fay was unable to complete his surveys due to political obstacles. On Jan. 17, 2007, Fay, Elkan and Marjan set out to...

Helping chlorine-eating bacteria clean up toxic waste

...n computer simulation of biochemical processes, to create computer models of the inner workings of the bacterium. The project is funded by a three-year, $381,000 grant from the Department of Defense, which has some 6,000 toxic-dump sites of its own to clean up. Richardson explained that in the field "the...

Ancient retrovirus sheds light on modern pandemic

...ng dozens of PtERV1 sequences and aligning them to create an "ancestral" sequence, teasing out areas of commonality between them. They then used this information to make a partial viral genome. During reconstruction the viral segment was debilitated, enabling only one round of infection in cells. Working wi...

Modified mushrooms may yield human drugs

...are going to be the platform of the future." To create transgenic mushrooms, researchers attached a gene that confers resistance to hygromycin, an antibiotic, to circular pieces of bacterial DNA called plasmids, which have the ability to multiply within a bacterium known as Agrobacterium. The hygro...

New vaccine prevents CMV infection and disease in mice

...ed that the next step is to apply this strategy to create a vaccine for use in humans. CMV is a virus that, while carried by the majority of adults in the United States, can remain dormant for years, if not the lifetime, of a healthy individual. However, two percent of all children are born with the vir...

The findings may have applications in treating post-traumatic stress disorder, where getting a patient to learn that a once-threatening situa...

New research shows sharks use their noses and bodies to locate smells
