NASA study finds snow melt causes large ocean plant blooms

...ease in phytoplankton could therefore cause oxygen deficiencies in the Arabian Sea to spread, leading to fish mortality. Oxygen-depleted waters also provide the perfect environment for the growth of a specialized group of bacteria called denitrifying bacteria. These bacteria convert a nitrogen-based nutrient rea...

One gene links newborn neurons with those that die in diseases such as Alzheimer's

...n, studies from other laboratories have pointed to deficiencies in UCHL1 in degenerative diseases such as Alzheimer's and Parkinson's. Experiments in mice confirmed the finding that low levels of UCHL1 correlate to the ability of neurons to be replaced. The researchers used similar techniques to assess UCHL1 in ...

The researchers injected these cells into rats that had experienced a partial injury to the spinal cord that impairs walking ability -- one group seven days after injury and another 10 months after inj...

Fundamental discovery -- Bone fracture

...iously unknown. Now the degradation mechanisms and deficiencies can be studied. "If you don't know something is important then you can't do anything about it. This is a fundamental and new discovery in an old and well-studied field," Hansma added. He noted that bone fracture is a serious problem for elderly peop...

...plies to Stat1. Children who are born with genetic deficiencies of Stat1 are also very susceptible to infection. In the more severe case, the children die in infancy of fatal viral infections. In less severe cases, they later develop infections due to mycobacteria. When interferon levels are too high, for example...

Metal homeostasis research in plants will lead to nutrient-rich food and higher yielding crops

...food in many of the countries with widespread Iron deficiencies in human diets. Guerinot's lab has previously identified the essential Iron transporter responsible for Iron uptake from the soil. This Iron transporter is IRT1. In addition to transporting iron, IRT1 can also transport Manganese, Zinc, Cobalt and...

"Normally, fast association of the protein with other biomolecules is critical for the creation of proper cell structures. The failure of t...

Putting an old drug to a new use

We all know that iron deficiencies are dangerous, but also too much iron is bad for our health. Our body stores excess iron in various tissues, where it can lead to organ failure and even death if not treated before irreversible damage has occurred. Researchers from the Innsbruck Medi...
