Synthetic Amino Acid Enables Safe Biotechnology Solutions

New research details the construction of a series of genomically recoded organisms (GROs) whose growth is restricted by the expression of multiple essential genes that depend on exogenously supplied synthetic amino acids. These GROs will ensure genetically modified organisms can be safely confined in the environment, overcoming a major obstacle to widespread use of GMOs […]

Black Hole Creates Changing Look Quasar

A team of astronomers from Yale University have identified the first “changing look” quasar, a gleaming object in deep space that appears to have its own dimmer switch. The discovery may offer a glimpse into the life story of the universe’s great beacons. Quasars are massive, luminous objects that draw their energy from black holes. […]

Study Shows Ribosomal Motor is Crucial Part of Cellular Protein Factory

New research from Yale University provides insights into the conformational space that EF-G samples on the ribosome and reveals that tRNA translocation on the ribosome is facilitated by a structural transition of EF-G from a compact to an elongated conformation, which can be prevented by the antibiotic dityromycin. The ribosome is the protein-making “factory” within […]

Geophysicists Reveal the Details Behind Sudden Tectonic Plate Movements

Geophysicists from Yale University reveal that the combination of crustal plugs with weakening causes abrupt slab detachment in a few million years, which can account for observed precipitous changes in plate tectonic motion and rapid continental uplift. Yale-led research may have solved one of the biggest mysteries in geology — namely, why do tectonic plates […]

Earth’s Earliest Primates Lived in Trees

New research from Yale University reveals that Earth’s earliest primates lived in trees. Earth’s earliest primates have taken a step up in the world, now that researchers have gotten a good look at their ankles. A new study has found that Purgatorius, a small mammal that lived on a diet of fruit and insects, was […]

Study Links Increased Impulsivity and Hostility With Recreational Marijuana Use

A newly published study from Yale University found that recreational marijuana use was associated with increased impulsivity and greater hostile perceptions and behaviors. While the negative effects of chronic marijuana use are being documented in a growing body of research, it has been unclear whether recreational use of the substance produces problematic effects in everyday […]

Study Shows Risk of Over Treatment in Older Diabetes Patients

New research from the Yale School of Medicine shows that aggressively controlling blood sugar with insulin and sulfonylurea drugs in older patients with multiple medical conditions could lead to over-treatment and hypoglycemia (low blood sugar). Published in the January 12 issue of JAMA Internal Medicine, the study found that many older diabetes patients received aggressive […]

New Research Shows Mass Animal Die-Offs May Be Increasing

A newly published study from Yale University shows that an increase in mass animal die-offs appears to be associated with a rise in disease emergence, biotoxicity, and multiple interacting stressors. Mass die-offs of animals may be increasing in frequency and — for birds, fishes, and marine invertebrates — in severity as well, according to a […]

How We Live in Harmony With Gut Bacteria

New research from Yale University identifies a strategy that non-harmful gut bacteria employ to preserve this stable relationship with their host during inflammation. Stability in the composition of the hundred trillion bacterial cells in the human gastrointestinal tract is crucial to health, but scientists have been perplexed how our microbiota withstands an onslaught of toxins, […]

Study Shows Broad Immune Response May be Needed to Destroy Latent HIV

A newly published study shows promise as the future direction for the development of a therapeutic vaccine to clear HIV. A major barrier to finding a cure for HIV/AIDS is the presence of latent HIV in the cells of chronically infected individuals. But a team of Yale and Johns Hopkins researchers may have pinpointed a […]

Schizophrenia Onset Linked to Elevated Neural Links

New research from Yale scientists, in conjunction with colleagues at the Huaxi Magnetic Resonance Research Center at Sichuan University in China, reveals that that the onset of the schizophrenia is marked by an abnormal spike in neural connections. In its chronic stage, schizophrenia is typically marked by a dearth of links between brain cells in […]

Study Shows Cold Virus Replicates Better at Cooler Temps

New research from Yale University shows that the common cold virus can reproduce itself more efficiently in cooler temperatures, reaffirming the popular, yet contested, notion that people are more likely to catch a cold in cool-weather conditions. Researchers have long known that the most frequent cause of the common cold, the rhinovirus, replicates more readily […]

Study Identifies Enzyme Crucial to the Shaping and Division of Brain Cells

A newly published study identifies a “cutting” enzyme crucial to the shaping and division of brain cells as well as the replenishment of neural stem cells. The study, appearing online December 17 in the journal Neuron, helps explain the molecular basis of complex brain abnormalities, including small brain size (microcephaly) observed in children who were […]

Nature and Nurture Vary Over Time

New research from Yale University shows that the effect of genes may depend on the total, historical environment in which the researcher and subject are embedded. Nature and nurture have found a new companion — historical context. A new study has produced the best evidence yet that the role of genetics in complex traits, including […]

Diabetes Drug May be Safe for Patients with Kidney Disease

A newly published study from Yale University reveals that metformin (the most popular treatment for type 2 diabetes) may be safer for patients with mild to moderate kidney disease than guidelines suggest. The new study is published by Yale investigators in the Journal of the American Medical Association (JAMA). For 20 years, metformin has been […]
