Yale Research Shows People with a Mental Illness are More Likely to Smoke

April 16, 2014

4 Comments

New research from Yale University shows that people with a mental illness are much more likely to smoke cigarettes and are less likely to quit smoking than those without mental illness. Those in the United States with a mental illness diagnosis are much more likely to smoke cigarettes and smoke more heavily, and are less […]

Neurobiologists Block the Effects of Stress

April 14, 2014

1 Comment

By deleting the REDD1 gene in mice, researchers from Yale University were able to block the synaptic and behavioral deficits caused by stress. Ketamine, an anesthetic sometimes abused as a street drug, increases the synaptic connections between brain cells and in low doses acts as a powerful antidepressant, Yale researchers have found. However, stress has […]

Study Reveals How and When Earth Developed Its Rigid Tectonic Plates

April 7, 2014

0 Comments

Newly published research from Yale University and Université de Lyon in France shows how and when Earth developed its rigid tectonic plates and why Venus never has. “We think it all comes down to the behavior of tiny grains of minerals within rocks,” said Yale geophysicist David Bercovici, lead author of research published online April […]

Deleting a Single Gene Reduces Fat Mass and Extends Lifespan of Mice by 20%

March 26, 2014

1 Comment

Researchers discover that mice without the FAT10 gene have an elevated metabolic rate, burn fat as fuel, exhibit reduced glucose and insulin levels, and age more slowly than normal mice. By deleting a single gene, researchers at Yale University were able to dramatically reduce fat mass in mice while expanding their lifespan by 20%. The […]

Neurobiologists Reveal Age-Related Changes that Answer Key Questions about Alzheimer’s Disease

March 19, 2014

0 Comments

In a newly published study, neurobiologists reveal age-related changes that help to answer key questions about Alzheimer’s disease. With advancing age, highly-evolved brain circuits become susceptible to molecular changes that can lead to neurofibrillary tangles — a hallmark of Alzheimer’s Disease, Yale researchers report the week of March 17 in the Proceedings of the National […]

A team of biologists has discovered 450-million-year-old fossilized crustaceans entombed with their eggs and newly hatched offspring, extending the knowledge of ostracods and confirming their presence in the Ordovician period. Scientists have found 450-million-year-old fossilized crustaceans entombed with their eggs and newly hatched offspring. At least one of the animals is a newly identified species. […]

Study Reveals Combination Therapies That Combat HIV at Cell Junctions

February 28, 2014

0 Comments

New research from Yale University reveals that cell-to-cell transmission of HIV particles contributes to the development of full-blown AIDS and helps predict which anti-retroviral therapies will be most effective at keeping the disease at bay. The new research reinforces recent findings that a heavy concentration of the virus at the point of contact between cells […]

Yale Researchers Find Hope for Safe and Novel Painkillers from Tarantula Venom

February 17, 2014

0 Comments

Yale researchers find new hope for safe and novel painkillers from the venom of the Peruvian green velvet tarantula. Screening more than 100 spider toxins, Yale researchers identified a protein from the venom of the Peruvian green velvet tarantula that blunts activity in pain-transmitting neurons. The findings, reported in the March 3 issue of the […]

Smoke from Wildfires and Forest Emissions Explain Why the Pliocene Was So Hot

February 7, 2014

1 Comment

Using sophisticated Earth system modeling, new research from Yale University reveals that the release of forest emissions and smoke from wildfires 3 million years ago had a far greater impact on global warming than ancient atmospheric levels of carbon dioxide. The research provides evidence that dynamic atmospheric chemistry played an important role in past warm […]

Researchers Identify Major Obstacle to Converting Cells Back to Their Youthful State

January 31, 2014

2 Comments

Researchers from Yale University have identified a major obstacle to converting cells back to their youthful state — the speed of the cell cycle, or the time required for a cell to divide. A fundamental axiom of biology used to be that cell fate is a one-way street — once a cell commits to becoming […]

Discovery Provides Clues to How Galaxies and Black Holes Develop Together

January 8, 2014

0 Comments

Using data from the Sloan Digital Sky Survey, researchers discovered more than 100 dwarf galaxies with massive black holes, providing an important step toward understanding how galaxies and black holes developed together. Poring through data from a large sky survey, astronomers have found more than 100 small, dwarf galaxies with characteristics indicating that they harbor […]

Study Shows Human Brain Development is Divided into Three Major Phases

December 27, 2013

1 Comment

In a newly published study, researchers analyzed gene expression in human and macaque monkey neocortex, finding that human neocortical development is divided into three major phases. The human brain develops with an exquisitely timed choreography marked by distinct patterns of gene activity at different stages from the womb to adulthood, Yale researchers report in the […]
