As they work together to form body parts, cells in developing organisms communicate like workers at a construction site. The discovery of a new signaling molecule in flies by Brown University biologists not only helps explain how cells send many long-haul messages, but also provides new clues for re...
Radioactive iodine found by Dartmouth researchers in the local New Hampshire environment is a direct consequence of a nuclear reactor's explosion and meltdown half a world away, says Joshua Landis, a research associate in the Department of Earth Science. The failure of the Fukushima Daiichi nuclear ...
The mere thought of an identification error sends a chill down the spine of any mushroom lover: The death cap mushroom (Amanita phalloides), which resembles the common white button mushroom, contains one of the most deadly poisons found in nature, α-amanitin.
Scientists studying 1,600-year-old cotton from the banks of the Nile have found what they believe is the first evidence that punctuated evolution has occurred in a major crop group within the relatively short history of plant domestication.
An international research team led by scientists from Singapore Immunology Network (SIgN) under the Agency of Science, Technology and Research (A*STAR) discovered that a special class of fatty molecules is essential for activating a unique group of early-responding immune cells.
Analysis of data from the 10-meter South Pole Telescope is providing new support for the most widely accepted explanation of dark energy - the source of the mysterious force that is responsible for the accelerating expansion of the universe.
Corals may be better placed to cope with the gradual acidification of the world's oceans than previously thought - giving rise to hopes that coral reefs might escape climatic devastation.
Scientists at Fox Chase Cancer Center have uncovered more details about how defects in components of the machinery that makes new proteins can lead to blood and other cancers. The findings, which will be presented at the AACR Annual Meeting 2012 on Monday, April 2, may one day lead to new targeted t...
Scientists at Cold Spring Harbor Laboratory have identified a candidate drug target for treating acute myeloid leukemia (AML), a white blood cell cancer that proliferates out of control in the bone marrow. The team, led by Assistant Professor Chris Vakoc, M.D., Ph.D., shows that blocking a protein c...
A study led by a University of Utah astrophysicist found a new explanation for the growth of supermassive black holes in the center of most galaxies: they repeatedly capture and swallow single stars from pairs of stars that wander too close.
A new study contrasting ocean temperature readings of the 1870s with temperatures of the modern seas reveals an upward trend of global ocean warming spanning at least 100 years.
The F-1 engine -- the most powerful single-nozzle, liquid fueled rocket engine ever developed -- boosted the Saturn V rocket off the launch pad and onto the moon during NASA's Apollo program during the 1960s and 1970.
