Astronomers have observed Z Cam binary system exhibiting a massive shell of gas and dust surrounding the white dwarf, indicating a classical nova explosion. The discovery supports a 20-year-old theory suggesting double-star systems cycle between blast types.
A new RNA map provides the first comprehensive understanding of how alternative splicing works throughout the genome. The results reveal that specific locations of short RNA snippets affect the regulation of alternative splicing in the brain, with implications for learning, memory, neurological diseases, and cancer biology.
The PBS/NOVA documentary 'Forgotten Genius' celebrates the life and work of Percy Julian, a trailblazing chemist who made significant contributions to the field. Julian's research led to the synthesis of physostigmine, a drug used in glaucoma treatment, and he was a pioneer in biomedical research.
A Canadian Medical Association Journal study finds that children living in low-income neighborhoods are at high risk of overweight and obesity. The research suggests that school programs promoting healthy lunches and physical activity could be effective preventive measures.
Paula Apsell won the Robert C. Cowen Award for her work on NOVA, while Madeleine Nash received the David Perlman Award for 'Fireproofing the Forests.' Kevin krajick became the first person to win the Walter Sullivan Award for 'Defusing Africa's Killer Lakes,'
Researchers have developed a new technique called CLIP, which helps identify target RNAs regulated by RNA-binding proteins like Nova. This technique has potential to aid in understanding the cause of many human diseases, including Fragile X syndrome.
Researchers have developed a new method called CLIP to catalog RNA targets regulated by RNA binding proteins in rare brain diseases. The study identifies an astonishing set of 340 Nova RNA tags, shedding light on the role of RNA splicing in POMA and other disorders.
The eSTAR network uses intelligent agents to automatically observe and analyze astronomical events, such as supernovae explosions and black hole activity. The agents can detect and respond to the rapidly changing universe faster than humans, allowing for more efficient science discovery.
Two NSF-backed public television science programs, 'Galileo's Battle for the Heavens' and 'The Secret Life of the Brain,' won Emmys in Historical Programming and Outstanding Science categories, respectively. The programs were funded under NSF grants and explored unique stories of science that would have taken volumes to tell.
A Canadian consortium, led by NOVA Chemicals and the Alberta Research Council Inc., has developed a new membrane technology to improve olefin production. The process aims to reduce energy costs and CO2 emissions in petrochemical plants, with potential economic and environmental benefits for industry and Canadians.
In Nova Scotia, a 52% increase in out-of-hospital cancer deaths between 1992 and 1997 was observed. This trend poses challenges for the healthcare system, particularly palliative care.
Researchers compiled a list of 46 phytoplankton species potentially toxic to humans and marine life, highlighting the need for monitoring programs. The study's findings emphasize the economic cost of harmful algae blooms and their potential impact on global climate modification.
Researchers have found unprecedented sea-level rise along the coasts of Maine and Nova Scotia, with rates of 30-60 cm since 1750. The finding suggests a two-step increase in sea level, caused by natural climatic warming followed by human-induced climate change.
A study analyzing perinatal records found that 33.1% of pregnant women in Nova Scotia smoked before their pregnancy, with 69.9% continuing to smoke throughout. An accompanying commentary provides guidance for physicians to increase smoking cessation rates among pregnant women.
New Hubble images show gas shells produced by novae that may revolutionize our understanding of galactic evolution. The findings imply that novae play a significant role in the distribution of heavier elements and planetary system development, contradicting previous predictions.
Astronomers have discovered expanding gas clouds thrown off by nuclear eruptions in stars, which provide reliable distances to these stars. The Hubble Space Telescope has captured detailed images of two nova shells, revealing structure and asymmetry, including polar blobs and equatorial rings.
