Earth's microbes help clean water and air and regenerate nutrients used by all life. Planktonic microbes, microscopic organisms that float freely in the oceans, h...

Enzyme inhibitors block replication of SARS virus

...nhibitors," Wong said. "They block the enzyme, are transformed through a co-valent bond, and are unable to get out." Wong said the findings published today provide better insight into the mode of action of the enzyme, which may lead to development of a drug against SARS. The findings were made by using rapid dr...

Waking a sleeping virus

...o them and allowing the information to be read and transformed into raw materials to make new viruses. "A good strategy in fighting viruses is to block the activation of viral genes," says Patrice Morand, a physician at the University hospital and the IVMS. "The drugs we currently use against EBV work that way...

Butterflies lose body fat during metamorphosis

...the diet as well as the larva. Once the larva had transformed into butterflies, the researchers examined the fatty acid composition and content of the butterfly. They found that both the diet and the tissues of the larva and butterfly had a high concentration of polyunsaturated fatty acids. However, the lar...

Absence of critical protein linked to infertility

...ancy to occur, stromal cells of the uterus must be transformed into decidual cells, which secrete nutrients that allow the embryo to survive until it plugs into the blood supply. C/EBPb is necessary for decidualization, the researchers discovered. "This protein in the mouse is also in humans," Bagchi said. "We ...

St. Jude projects 90 percent cure rate for ALL

...tiple breakthroughs at St. Jude and elsewhere have transformed ALL from a virtual death sentence into a disease that children can increasingly be expected to survive with minimal side effects," Evans said. "Surpassing 90 percent is an important step toward our ultimate quest of curing all children with this dise...

Potential heart benefit found in stem cells

...oximately half of the stem cells were successfully transformed into cardiomyocytes (premature cardiac functioning cells) in vitro. "We believe that by looking at these new sources for stem cells, we will eventually be able to use our own stem cells to repair our own heart dysfunctions," said Sunichiro Miyoshi...

Strawberries by design

...o the presence of Green Fluorescent Protein (GFP), transformed strawberry plants may be easily identified by visual inspection. This is the first time that GFP has been used in strawberry as a visually selectable marker. Commenting on the research, VBI Professor Vladimir Shulaev, one of the authors of the stu...

Retinol for combating leukemia cells

...is vitamin is accumulated in the liver where it is transformed into retinoid. Given that vitamin A, as such, has no effect on our organism, it is the retinoids that are responsible for the physiological activity of the vitamin. Retinoids take part in three processes: in cell death, in cell differentiation and i...

Microbes transform 'safest' PBDEs into more harmful compounds

...BDEs into benign components. Instead, the microbes transformed deca-BDEs into octa-BDEs and the octa-BDEs into th...that certain PBDEs found in the environment can be transformed into more toxic forms, we need to make more intelligent policy decisions with respect to how, or eve...

All the eggs in one basket

...chers, "The ecological extinction of green turtles transformed an ecosystem with diverse species of seagrass dominated by large herbivores into a detritus-based ecosystem dominated by overgrown monocultures of one species of grass." Green turtles feed mostly on turtle grass, while hawksbill turtles prefer mari...

Bone marrow may restore cells lost in vision diseases

...wed the cells that traveled to the injury site and transformed into RPE indeed had male genetic characteristics. Furthermore, these cells were capable of producing pigment - a colorful indication that the RPE could only have arisen from the donor bone marrow stem cells. "We did not use a direct model of age-rel...

Vaccine combined with short-term postexposure antibiotics protects monkeys from inhalational anthrax

...s of the lung. When the spores germinate, they are transformed into vegetative cells that produce three components contributing to virulence--lethal toxin, edema toxin, and capsule. The capsule surrounds the vegetative cell and prevents it from being ingested by host white blood cells that would otherwise destro...

Perceived facial similarity in children is an estimate of kin recognition

...s by the second group. These ratings could also be transformed into accurate estimates of the probability that a given pair of children portrayed siblings. The study was conducted by researchers Laurence T. Maloney, of New York University's Psychology Department and Center for Neural Science, and Maria F. Dal Ma...

The first tree genome is published: Poplar holds promise as renewable bioenergy resource

...pply of tree biomass rich in cellulose that can be transformed by specialized biorefineries into fuels like ethanol. Other regions of the country might specialize in different "energy crops" suited to their particular climate and soil conditions, including such plants as switchgrass and willow. In addition, a ...

Discovery of the first resistance gene to rice yellow mottle virus

...or susceptibility of this gene. The descendents of transformed plants that manifested restored susceptibility always showed the presence of the transgene . Viruses are built with a small genome coding for a limited number of proteins (5 in the RYMVs). They therefore need their host's proteins in order to accom...

'Protecting virus' offers instant flu protection and converts flu infections into their own vaccines

...tion to such an extent that harmful infections are transformed into a vaccine against that form of influenza. 'Protecting virus' has a significant alteration to one of the virus's genes. The genetic material of a flu virus consists of 8 individual segments of single stranded RNA. Professor Dimmock's protecti...

Compound eyes, evolutionary ties

...ction of spacemaker into eyes with a closed system transformed them into an open one. Charles Darwin was so enamored by the intricate complexity of the eye that he wondered how it could have evolved. "These results help illustrate the beauty and power of evolution and show how 'little steps'--like the presen...
