Soils offer new hope as carbon sink

...and the control plots. "For the wheat, agrichar alone was about as beneficial for yields as using nitrogen fertiliser only. "And that is without considering the other benefits of agrichar." Regarding soil chemistry, Dr Van Zwieten said agrichar raised soil pH at about one-third the rate of lime, lif...

Study finds mix of disease processes at work in brains of most people with dementia

...ng two people with all three conditions). Infarcts alone caused another 12 percent of the cases. Also, 80 of the 141 volunteers who died had sufficient Alzheimer’s disease pathology in their brains to fulfill accepted neuropathologic criteria for Alzheimer’s disease, although in life only 47 were clinicall...

Reconstructing the biology of extinct species: A new approach

...omotor pattern is evident both within the primates alone and within the entire mammalian sample. "How an animal moves is a basic adaptation," says Walker, an expert in primate locomotion. "Now we have a way to reconstruct how extinct species moved that is completely independent of analysis of the limb ...

Male circumcision overstated as prevention tool against AIDS

...nter, reducing single encounter transmission rates alone cannot control the epidemic. The reason is that individuals in highly infected countries have multiple contacts with the infected so reducing transmission rates only defers the inevitable. The real question is what can be done with the prostitute ...

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

New vaccine prevents CMV infection and disease in mice

... generates an antibody response. Neither approach alone would give complete protection. “In mice, the vaccine not only fought the disease, but prevented the infection from being established in the first place,” Morello said. Researchers at UCSD hope to begin pre-clinical work on development of a h...

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

Smallpox outbreak: How long would it take for vaccines to protect people? Would it work?

...sed vaccine. The new vaccine will be given either alone or in combination with Dryvax. "Another purpose of the study is to see how quickly people can be protected against smallpox after a release of smallpox into the environment," Frey said. Dryvax® vaccine is the original Food and Drug Administratio...

Peramivir protects mice from lethal H5N1 infection

...inistration of peramivir (intramuscular injections alone versus intramuscular injections followed by oral administration) and frequency of administration on the first day of treatment (once versus twice). In all cases, the investigators administered peramivir to mice one hour after nasally administering a ...

Scientists identify prion's infectious secret

...element was activated. In other words, temperature alone could dictate which yeast species the prion could infect. Additionally, the prion’s behavior could be altered by subtle alterations in the recognition element’s amino acid sequence. While this prion is a laboratory construct not found in nature, ...

Researchers publish first marsupial genome sequence

...ratory animal known in which ultraviolet radiation alone can cause melanoma, a type of skin cancer that also strikes humans exposed to too much of the sun's ultraviolet rays. Having the sequence of the opossum genome will give researchers the ability to learn more about the molecular basis of melanoma and ...

Dealing deadly cancers a knockout punch

...several presentations focused on reovirus efficacy alone or in combination with standard chemotherapies. ...ficantly more effective than cisplatin or reovirus alone at killing melanoma cancer cells in a mouse model. The investigators intend to explore the mechanis...

The quest for an effective HIV vaccine presents new possibilities, challenges

...oes not completely prevent disease could not stand alone as a preventive measure; the public health community would need to include it as part of a broader HIV prevention program, so that recipients would minimize, or ideally, not engage in high-risk behaviors, according to the authors. Currently, sever...

In young mice, gregariousness seems to reside in the genes

... emotional states, depending upon whether they are alone or with others, and that specific genes may influence how they feel within different social contexts. Identifying the gene or genes at play, says Lahvis, is the next step. "We now know that social motivation can be responsive to genetic factors, b...

Cure for cancer one step closer

...ancers, particularly melanoma. The Wesley Hospital alone had almost 2000 cancer related surgeries in 2004. The Queensland Government contributed $1.42 million towards the construction of the Tissue Bank through the Smart State Research Facility Fund. The investment has built and equipped, as part of ...

Transfusion expert urges wider use of filtered blood

...he savings in treating heart surgery complications alone could total $1 billion a year, nationwide. "Rarely do we come up with a medical advance that saves money and is better for patients at the same time. This is as basic as washing your hands before conducting a physical examination of a patient," B...

In obesity, brain becomes 'unaware' of fat

...always supported the idea that reducing fat intake alone has a major effect on obesity, noting that the digestive systems of mice and humans differ substantially. His team has plans to examine these effects in overweight primates, whose digestive systems have much more in common with people. The finding...

Action video games sharpen vision 20 percent

...d few, if any, video games in the last year. "That alone was pretty tough," says Green. "Nearly everybody on a campus plays video games." At the outset, the students were given a crowding test, which measured how well they could discern the orientation of a "T" within a crowd of other distracting sy...

Study calculates patient time costs associated with cancer care

..., the estimated cost for the initial phase of care alone was approximately $2.3 billion," the authors write. These estimates could be combined with estimates of direct and indirect costs to better understand the overall burden of cancer in the United States, the authors write. "What we see here is a meas...

Little is known about the behavior of mercury in marine ecosystems and methylmercury in marine fish, the ingestion of which is the primary ...
