New Haven, Conn. — In a new study, Yale University researchers have identified a pathway by which reactive oxygen species (ROS) molecules, which are usually implicated in the aging process due to their damage to DNA, can also act as cellular signaling molecules that extend lifespan. The study, which provides insights into the underlying mechanisms […]
Particle Trap Paves Way for Personalized Medicine
Scientists were able to trap a single particle between four microelectrodes, paving the way for a faster and cheaper way to sequence DNA. (Photo: Weihua Guan and Mark Reed) New Haven, Conn. — Sequencing DNA base pairs — the individual molecules that make up DNA — is key for medical researchers working toward personalized medicine. […]
Yale Researchers Find Clues to Mystery of Preterm Delivery
New Haven, Conn. — Researchers at Yale School of Medicine have found that excessive formation of calcium crystal deposits in the amniotic fluid may be a reason why some pregnant women suffer preterm premature rupture of the membranes (PPROM) leading to preterm delivery. This is a key breakthrough in solving the mystery of preterm birth, […]
Yale and New Haven to Host More than 550 Science Writers
New Haven, Conn. — More than 550 science journalists will be in New Haven Nov. 5-9 as Yale University and the Yale School of Medicine host ScienceWriters2010, the combined annual meeting of the National Association of Science Writers (NASW) and the Council for the Advancement of Science Writing (CASW). The conference will feature professional workshops […]
Evolutionarily Young Protein Helps Ancient RNA Get Into Shape
How A Protein Helps Fold RNA. New Haven, Conn. — Scientists once believed that proteins govern most cellular activities. However in recent years scientists have found that a diverse group of RNA molecules regulate numerous biological activities. Despite their ancient origin, these RNA molecules have come to rely on younger protein partners to carry out […]
Dangerous Bacterium Hosts Genetic Remnant of Life’s Distant Past
New Haven, Conn. — Within a dangerous stomach bacterium, Yale University researchers have discovered an ancient but functioning genetic remnant from a time before DNA existed, they report in the August 13 issue of the journal Science. To the surprise of researchers, this RNA complex seems to play a critical role in the ability of […]
In the Bacterial World, Genetic Messengers Work Close to Home
New Haven, Conn. — In a fundamental shift in the view of how bacteria proliferate and survive, Yale scientists report online June 20 in the journal Nature that most of the genetic action within a cell takes place close to home. Since bacteria lack internal compartments such as a nucleus, scientists had long assumed that […]
