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

...ience surrounding genetically modified crops. The results are significant for how we think about technology and the future of sustainable agriculture,” said Peter Kareiva, chief scientist of The Nature Conservancy. According to lead author, Michele Marvier, of Santa Clara University, “We can now answer ...

Research shows cord blood comparable to matched bone marrow

... main objective of the research was to compare the results after cord blood and marrow transplantation and provide guidelines to transplant physicians on the selection of the best donor for children with leukemia. Remarkably, mismatched cord blood performed as well as matched bone marrow as measured by leuk...

Salty oceans provide early warning for climate change

...reasingly 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 ...

Sun exposure early in life linked to specific skin cancer gene mutation

...ter in life (between ages 50 to 60 years old). The results indicate that different subtypes of melanoma are associated with different risk factors "The findings suggest that melanoma subtypes have different causes. This is important for learning more about how to prevent and treat skin cancer," said Dr. N...

Dual-imaging technique useful before -- and during -- brain surgery

...andard visual, sound, and voice-based tests, whose results are measured by MRI, performed on a high-field-strength (3 Tesla) scanner, with a precise intraoperative guidance system will improve patients’ post-operative speech, movement and memory, and also optimize quality of life for those with brain tumors ...

Rising skin cancer rates are more likely to affect wealthy people, says 12-year review

...e Royal Victoria Hospital. “This means that our results are less likely to be affected by different skin tones and ethnic origin than research carried out in countries with a greater ethnic mix.” The authors point out that the general increase in incidences of skin cancer, coupled with ageing populatio...

U-M researchers discover gene switched off in cancer can be turned on

...l lines in particular, although they found similar results in a variety of other cancer cell lines tested. A potential target to treat lung cancer is particularly crucial as the death rate from lung cancer has not changed in 30 years. Newer treatments are much less toxic and extend lives by months, but the s...

Researchers shed light on mechanism of action used by anti-cancer drug

... known as endoplasmic reticulum (ER) stress, which results from accumulation of misfolded proteins in the ER. The ER is a subcellular structure which plays a key role in cellular protein disposition. When stressed in this way, the cell responds to the protein load by reducing protein synthesis, increasing le...

Researchers reveal structure of protein altered in autism

...d University of Utah. Incorrect partnering that results when a mutant neuroligin fails to properly align at synapses helps explain why the autism spectrum disorders are manifested in subtle behavioral abnormalities that are seen at an early age. “Abnormal synaptic development in nerve connections is li...

Women well informed about breast cancer, yet lacking knowledge about current treatments

...e toward better treatment. “These survey results suggest that many women still lack essential disease treatment information, which reinforces the need for women to educate themselves to help get the best treatment,” said Diane Blum, MSW, executive director of CancerCare. “While great progress has ...

Genetic factors are linked to fever following smallpox vaccination

...nes. Both Drs. Stanley and Crowe mention that the results may have important implications when it comes to the future goal of identifying individuals at risk for fever before they are given a specific vaccination. Crowe writes, “The long-term goal is to determine genetic features that could be determined p...

MU researchers to study the status of black bears in Missouri

...tinct in Missouri since the late 19th century. The results of the MU study will be used by the Missouri Department of Conservation to help manage Missouri’s black bear population. The researchers – Kaitlyn Faries, a senior biology and chemistry major, and Lori Eggert, assistant professor of biological scien...

Small, self-controlled planes combine plant pathology and engineering

... be new to science.” This and other fascinating results have led Schmale to hypothesize that some airborne microorganisms have “novel biochemical processes for interacting with each other as a community of organisms in the atmosphere.” He explained, “We know that microbes mediate important biochemical pro...

Penn researchers link cell's protein recycling systems

...roteasome is disabled by a genetic mutation, which results in neurodegeneration. They use the fly eye, a neuron-rich tissue, as a surrogate for the brain because it is easy to visualize. They discovered that making the lysosomal system more or less active dramatically influenced the severity of neurodegenera...

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

454 sequencing identifies HIV drug resistance at early stage

... drug treatment from HIV infected individuals. The results were presented today at the XVI International HIV Drug Resistance Workshop in Barbados and showed that the fraction of patients that harbored resistance mutations is at least twice as high as previously thought. Most low level mutations are undetecta...
