The air we breathe contains particulate matter from a range of natural and human-related sources. Particulate matter is responsible for thousands of premature deaths in the US each year, but legislation from the US Environmental Protection Agency (EPA) is credited with significantly decreasing this number, as well as the amount of particulate matter in the atmosphere.
The toxic dinoflagellate, Alexandrium fundyense, is a photosynthetic plankton — a microscopic organism floating in the ocean, unable to swim against a current. New research by scientists at the University of Hawai'i at Manoa (UHM) School of Ocean and Earth Science and Technology (SOEST) suggests that ingestion of this dinoflagellate changes the energy balance and reproductive potential of a particular copepod — a small crustacean — in the North Atlantic, which is key food source for young fishes, including many commercially important species.
A senior lawyer of the Supreme Court of India on Tuesday put the responsibility of the disastrous stampede in Mina on the Saudi Arabia government and called for filing a case against Riyadh in the International Court of Justice (ICJ)
A study from the University of Copenhagen reveals that every single person on the Earth had brown eyes until a genetic mutation occurred around 10,000 years ago. Researchers interpret that all people with blue eyes share a common ancestor.
After generating new brain tumor models, scientists of Cedars-Sinai Medical Center, California, identified the role of a family of genes underlying tumor growth in a wide spectrum of high grade brain tumors.
Researchers at the University of Adelaide have identified that the activation of the TLR4 molecule is key in controlling the timing of birth, acting as a trigger common to both preterm and on-time labor.
In the most severe form of male infertility, men do not make any measurable levels of sperm. This condition, called azoospermia, affects approximately one percent of the male population and is responsible for about a sixth of cases of male infertility.
