Researchers using supercomputer simulations have exposed a very violent and critical relationship between interstellar gas and dark matter when galaxies are born – one that has been largely ignored…

Al Gore showing pictures of the Hurricane Katrina disaster without coming right out and claiming global warming caused it was a little too clever for some atmospheric scientists but a group of…

No other stem cell is more thoroughly understood than the blood, or hematopoietic, stem cell. These occasional and rare cells, scattered sparingly throughout the marrow and capable of replenishing an…

Fertilizing the ocean with iron or other nutrients to cause large algal blooms, has been proposed as a possible solution to global warming because the growing algae absorb carbon dioxide but research…

Astronomers at the University of Illinois have found the first clear evidence for a cradle in space where planets and moons form. The cradle, revealed in photographs taken with NASA’s Spitzer Space…

Meiosis is a type of cell division that produces cells with only one copy of each chromosome—spores in yeast, and eggs and sperm in higher organisms. During meiosis, chromosome pairs line up in the…

Scientists analysing data gathered by Cassini have confirmed the presence of heavy negative ions in the upper regions of Titan’s atmosphere. These particles may act as building blocks for more…

It's hard to say when scientists realized that policy makers were not always going to make the best decisions regarding science funding but a safe bet would be somewhere before 3,000 BC. In the…

“When biologists talk about the ‘Battle of the Sexes,’ they often tacitly assume that the battle is between persistent males who always want to mate and females who don’t,” says Jakob Bro-Jørgensen…

Astronomers at the University of Michigan have found what are believed to be some of the youngest solar systems yet detected. The systems are around the young stars UX Tau A and LkCa 15, located in…
