Apparently, the lowly fern deserves more respect. New research scheduled to appear as the journal Nature's cover story on February 1 concludes that ferns and horsetails are not -- as currently believed -- lower, transitional evolutionary grades between mosses and flowering plants.

Normal salt levels in the lung of the cystic fibrosis mouse
The physical and chemical properties of the airway-surface liquid (ASL) of the lung are believed to be perturbed in cystic fibrosis, but precisely how they differ from conditions in the healthy lung, and why such a disturbance should render the lung sensitive to infections are hotly disputed.

Study of dendritic cell 'vaccine' shows early promise in helping the immune system combat an extremely aggressive type of brain cancer
The existing methods of treating brain tumors have been virtually powerless against an extremely deadly type of tumor called glioblastoma multiforme (glioma).

Cell membrane plays crucial role in releasing nitric oxide from red blood cells
Duke University Medical Center researchers report that the membranes of red blood cells are actively involved in storing and releasing nitric oxide, a molecule that regulates blood flow and oxygen delivery in humans.

How did uranium get into space?
A month before the Mir Space Station is due to crash into the Pacific Ocean, tiny radioactive specks of uranium have been found on one of its instrument covers.

Most pollution from cars is spewed out in the first few minutes, as the car warms up.

Ovarian stimulation in mice adversely affects embryo development and implantation
Norwegian researchers have shown that, in mice, stimulating the ovaries with hormone drugs to produce more eggs appears to impair the development of the embryo and its likelihood of implanting.

Untangling prostaglandin signaling
Prostaglanin E2 (PGE2)signaling contributes to each of the manifestations that classically define inflammation--redness, heat and pain.

Massachusetts General Hospital (MGH) researchers have identified a new - and surprising - mechanism by which breast cancer cells metastasize to the lymph nodes and lungs.

What is mass?
What is this thing called mass? Pondering this apparently simple question, two scientists have come up with a radical theory that could explain the nature of inertia, abolish gravity and, just possibly, lead to bizarre new forms of spacecraft propulsion.

Astronomers gain best glimpse yet of what our universe is made of -- and not much of it is matter as we know it
In the most accurate picture yet of the makings of our universe, astronomers have determined that a measly 5 percent of its mass comes from the ordinary matter that makes up planets, stars and gases.

O.R. study suggests safety benefits from free flight routings.
Free flight, which would cut travel time by routing air traffic directly between airports, might be just as safe as the current air traffic control system that holds airplanes to grid paths, according to a preliminary study published in a journal of the Institute for Operations Research and the Management Sciences (INFORMS®).
