Fighting influenza & co. with 40,000 blood samples

...al EU project led by the University of Bonn is now starting which aims at shedding light on this. Among other things, the researchers want to get a step closer to solving this riddle by examining tens of thousands of blood samples. The objective is also to develop new medicines which largely inactivate the vi...

How trees manage water in arid environments

... rainfall. The monsoon varies from year to year in starting date, duration and intensity. "The semi-arid forest ecosystem adapts to the extremes in the annual cycle of water availability by its ability to remain turned on during the winter," Brown said. "Water stress, rather than temperature, is the primar...

30+ AIDS vaccine clinical trials in 24 countries, research occurring on every continent

...development efforts. The company will also soon be starting an additional Phase IIb trial with the same candidate in South Africa. The Joint United Nations Programme on HIV/AIDS (UNAIDS) estimates that 4.3 million people were newly infected with HIV last year—bringing the total number of HIV-infected ...

Sandia researchers take new approach to studying how cells respond to pathogens

...em by the immunology research community. "We're starting with robust and well-characterized cells, which really simplifies development of our new technologies and methods," Singh says. "We'll soon be working with other cell types, though, like white blood cells directly isolated from human patients. Our ap...

Noise echoes in cell communications

...he Rutgers-Camden research team used bacteria as a starting point for observing how noise enhances cell-to-cell communication. A full understanding of how this simple form of communication works might show how to disrupt it, and the resulting infection. The team will next apply their idea to the nervous syst...

Fish extinctions alter critical nutrients in water, study shows

... phosphorus were maintained at 80 percent of their starting values until over half the total number of species were lost. Studies of complex ecosystems, especially those involving large, highly mobile fish, are almost impossible to carry out in the wild, but new methods are helping researchers better unders...

HIV survival improves if patients stay in care

... on the number of quarters in the first year after starting treatment that they visited their HIV physicians o... visited the physicians less during the year after starting treatment had a greater risk of dying than those who saw the physicians at least once each quarter. ...

The longest carbon nanotubes you've ever seen

...part hydrocarbons to create a vapor of carbon-atom starting material. Within the vapor sat the new substrate--a catalyst made of alternating metal and ceramic layers atop an oxidized-silicon wafer base--which served as the foundation for growth. "This process is revolutionary because it allows us to keep t...

New technique will produce a better chromosome map

... structure to look at," Novikov said. "This is the starting point: the appearance of the genes themselves." Cell and developmental biology professor and lead investigator Andrew S. Belmont and visiting scientist Igor Kireev, of Moscow State University, are co-authors on the paper. Belmont is in the U. of I...

Gene expression patterns predict rapid decline in idiopathic pulmonary fibrosis patients

...l slower progressing patients. "We are only now starting to really understand IPF and to characterize it," Dr. Kaminski said. "Therefore, it is critical for patients with the disease to be seen in centers that are actively involved in IPF research, so we can help them better decide a course of action." ...

Extra-aggressive form of idiopathic pulmonary fibrosis identified

...on patients with IPF as possible. "We are only now starting to really understand the disease and characterize it," he said, "therefore, it is critical for patients with the disease to be seen in centers that are actively involved in IPF research." Better identification and understanding of these difference...

Avian influenza survivors' antibodies effective at neutralising H5N1 strain

...m to rapidly reproduce human monoclonal antibodies starting from a small sample of blood. "We can't say for certain that a pandemic influenza virus will resemble the H5N1 strain that we have been studying or that the monoclonal antibodies generated using our technique will be able to tackle such a virus," ...

Plants recognize their siblings, biologists discover

...s get along better than others, and scientists are starting to catch up with why that happens,” says Dudley. “What I’ve found is that plants from the same mother may be more compatible with each other than with plants of the same species that had different mothers. The more we know about plants, the more comp...

Researchers reveal structure of protein altered in autism

...auses autism, but this research represents a solid starting point,” said Sarah Dunsmore, Ph.D., program director with the National Institute of General Medical Sciences, part of the National Institutes of Health, which partly supported the study. “The work suggests that genetic mutations that alter the shape...
