The Joint Mathematics Meetings bring together researchers and educators to advance mathematical achievement and encourage innovation. The event features over 1300 research papers and high-profile events such as the debut of Who Wants To Be A Mathematician.
A new study has successfully mapped the global extent of 'iron-limited' ocean regions, which are crucial for understanding how the ocean's biology controls the flow of carbon between the atmosphere and the ocean. These regions were identified by analyzing satellite data on dust deposition and phytoplankton productivity.
Researchers from Vanderbilt University have discovered that the genes bozozok (boz) and chordino (din) cooperate to limit BMP activity during embryological development, allowing for the formation of the head and trunk. This discovery highlights a simple mechanism underlying vertebrate head and trunk specification.
Researchers found that four-fifths of fall chinook salmon females in the Hanford Reach of the Columbia River carried a genetic marker linked to males. The study suggests environmental contaminants or water temperature changes may be responsible for this sex reversal, which could contribute to the decline of Northwest salmon runs.
The American Chemical Society is offering a $750,000 minority scholars program to support high school seniors and college students pursuing careers in chemistry. The program aims to provide renewable scholarships of up to $3,000 per academic year to attract qualified candidates from underrepresented groups.
Researchers discovered that only two genes, BMP and Bozozok, regulate head formation in zebrafish embryos. The study suggests that these genes also play a role in limiting BMP function, allowing for proper organ development.
Joseph L. Reid, a renowned physical oceanographer, is being honored with the Maurice Ewing Medal for his significant contributions to understanding ocean circulation and currents in the Pacific, Atlantic, and Indian oceans. His work has also focused on current exchanges between major oceans.
A study by Slawek Tulaczyk and Marion Bougamont reveals that the West Antarctic ice stream may slow down and stop moving altogether, leading to thinning and shrinking of the ice shelves. This could have dramatic consequences for global ocean circulation and climate.
The Arabidopsis thaliana plant's genetic evidence suggests it emerged between 50 and 200 million years ago. Researchers used computational tools to analyze its genome, finding duplicated chromosome segments that date back to ancient polyploid events, providing insights into the evolution of agricultural crops.
A new study reveals that one-fifth of young adult cancer survivors exhibit symptoms of posttraumatic stress disorder, a condition characterized by overwhelming anxiety and fear. The study found a four-fold increase in PTSD diagnosis among young adults compared to those aged 9-17.
A study by Dr. Dallas Swallow and colleagues found that the lactase gene was shaped by two evolutionary periods: one before and one after fresh milk became available. The researchers discovered that genetic diversity in non-African populations is lower than in Africans, suggesting a loss of genetic variation due to random fluctuations ...
Scientists have calculated a lower strange quark contribution and discovered evidence for the proton's anapole moment, a parity-violating electromagnetic effect. The findings suggest less than 6% of the proton's magnetic moment arises from the strange quark.
The American Association of Pharmaceutical Scientists (AAPS) is hosting a workshop on bioanalytical methods validation, which aims to review progress since the first workshop in 1989. The event will focus on identifying and resolving scientific issues related to quantitative bioanalytical methodology.
Research suggests that most of the time during the Late Heavy Bombardment period, conditions on Earth were livable for microbes. The team's study indicates that only rarely would severe bombardment have made survival at the surface difficult, allowing hardy bacteria and viruses to find sheltered places to ride out the storm.
The IMAGE far-ultraviolet camera has captured breathtaking auroras visible from Georgia, Florida, and Texas, revealing minute details in their structure and shape. The camera's ability to image invisible ion auroras has greatly expanded scientists' understanding of the Earth's magnetosphere.
A Harvard Medical School study found that immune proteins Class I MHC and CD3-zeta play a role in brain development and remodeling, potentially triggering developmental disorders like dyslexia. The proteins may also be involved in neurodegenerative diseases such as Parkinson's disease and multiple sclerosis.
Researchers expect Arctic ozone layer recovery to be slower than expected due to unusually low stratospheric temperatures and increasing greenhouse gases. The phase out of chlorine-containing chlorofluorocarbons and halons has not slowed down ozone losses over the Arctic, with significant losses observed last spring.
A seven-year study by University of Florida researchers found a 73% drop in mercury levels in wading bird chicks' feathers since 1994. The declines may be linked to the removal of mercury from commercial products and industrial processes, starting in the late 1980s.
Researchers found a record warming event in Antarctica around 19,000 years ago, with temperatures rising up to 18 degrees Fahrenheit in just a few decades. This event may have been the trigger for the end of the last ice age and rivalled strong warming events in the Northern Hemisphere.
