Maunakea, Hawaii - A team of astronomers has discovered a new way to unlock the mysteries of how the first galaxies formed and evolved.
In a study published today in Astrophysical Journal Letters, lead author Dawn Erb of the University of Wisconsin-Milwaukee and her team - for the very first time - used new capabilities at W. M. Keck Observatory on Maunakea, Hawaii to examine Q2343-BX418, a small, young galaxy located about 10 billion light years away from Earth.
For the first time in the U.S., a blood test will be available to help doctors determine if people who've experienced a blow to the head could have a traumatic brain injury such as brain bleeding or bruising.
Scientists have discovered that some treatments for cancer and sickle cell disease can destroy the germ cells that go on to develop into sperm in the testes of young boys. In some pre-pubescent boys, the treatment for sickle cell disease results in complete destruction of all their germ cells, which are called spermatogonia.
Two years after a CIRES and CU Boulder team discovered a previously unknown class of waves rippling continuously through the upper Antarctic atmosphere, they've uncovered tantalizing clues to the waves' origins. The interdisciplinary science team's work to understand the formation of "persistent gravity waves" promises to help researchers better understand connections between the layers of Earth's atmosphere--helping form a more complete understanding of air circulation around the world.
The dust that coats much of the surface of Mars originates largely from a single thousand-kilometer-long geological formation near the Red Planet's equator, scientists have found.
A study published in the journal Nature Communications found a chemical match between dust in the Martian atmosphere and the surface feature, called the Medusae Fossae Formation.
A research team from the Center for Biomedical Research (CBMR), at the University of Algarve (UAlg), and Instituto Gulbenkian de Ciência (IGC), led by Rui Gonçalo Martinho (UAlg) and Paulo Navarro-Costa (UAlg and IGC) has identified the mechanism by which the fertilized egg balances out the differences between chromosomes inherited from the mother and the father. The study, now published in the scientific journal EMBO reports*, may pave the way for future developments in the clinical management of infertile couples.
Infrared satellite imagery provides temperature data, and when NASA's Aqua satellite passed over Tropical Storm Wukong, the coldest cloud tops circling the center resembled a strawberry and leaf.
Cloud top temperatures determine strength of the thunderstorms that make up a tropical cyclone. The colder the cloud top, the stronger the uplift in the storm that helps thunderstorm development. Basically, infrared data helps determine where the most powerful storms are within a tropical cyclone.
Borderlands are synonymous with desolation, but the Mexico-U.S. divide is something altogether different. The nearly 2,000-mile-long border traverses some of the continent's most biologically diverse regions, including forests, grasslands and salt marshes - home to more than 1,500 native animal and plant species, according to an analysis published in BioScience on July 24.
Amidst increased tensions over the US-Mexico border, a multinational group of over 2500 scientists have endorsed an article cautioning that a hardened barrier may produce devastating ecological effects while hampering binational conservation efforts. In the BioScience Viewpoint , a group led by Robert Peters, William J. Ripple, and Jennifer R. B.
LONDON, ON - An international collaborative study between Lawson Health Research Institute, Memorial Sloan Kettering Cancer Center, the Royal Marsden and Epic Sciences is one of the first to demonstrate that a blood test can predict how patients with advanced prostate cancer will respond to specific treatments, leading to improved survival.
