...embrane and surrounding structures. This breakdown allows red blood cells and proteins that are normally retained in the glomerulus, to pass into the urine. They went on to show that dietary supplementation with ManNAc improved the structure of this membrane and prolonged the life of these animals. In an ...Cells re-energize to come back from the brink of death

The St. Jude study also suggests that a drug that disrupts a cancer cells ability to block this backup program would allow that program to kill the cell. Such a specifically targeted drug might be more effecti...Research finds evidence tropical cyclones have climate-control role
...rm water lessens the density of the cold water and allows it to rise " The study did not examine deep ocean mixing, but it is reasonable to speculate that warm water pumped down joins the ocean circulation and becomes a part of the upper limb of the conveyer belt where dense water makes it up to the surfa...Magnetic field uses sound waves to ignite sun's ring of fire
...ns, the results show that the sun's magnetic field allows the release of wave energy from its interior, permitting the sound waves to travel through thin fountains upward and into the solar chromosphere. The magnetic fountains form the mold for the chromosphere. Researchers say that it's like standing in ...How E. coli evolves to adapt to changing acidity

When the team tested their approach on a simulated model of ocean current flow, they found that regions where dr...Avian influenza survivors' antibodies effective at neutralising H5N1 strain

And for most rural women, making even one repeat visit to a clinic to learn the results of a test and be treated is too much of a personal burden.

... leaf monkeys, all have trichromatic vision, which allows these primates to distinguish between blue, green and red colors. Primatologists have disagreed about whether this type of color vision initially evolved to help early primates forage for ripe fruit and young, red leaves among green foliage or evolve...MIT researchers probe bones' tiny building blocks

For example, certain kinds of a new class of materials called nanocomposites are composed of a polymer or metallic matrix filled with nanoscale particles randomly distributed o......ists of a soil retriever that, for the first time, allows large-volume cores of earth to be removed from lysimeters without destroying the existing stratification and structure of the soil. Lysimeters are stainless steel cylinders around 2 to 4 metres in height that are filled with soil and inserted into t...Leading the fight against food poisoning

A similar "switch" may be responsible for timing the sleep cycle in humans. "We were interested in trying to understand behavior at the mo......ith Higgins and others. "Identifying individuals allows us to actually count how many animals are in different areas, which is essential information for monitoring their conservation status," says Justina Ray, director of Wildlife Conservation Society Canada.
