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

April 16, 2014

5 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 […]

Newly Designed Nanoparticles Can Deliver Three Cancer Drugs at a Time

April 15, 2014

2 Comments

In a newly published study, MIT chemists detail how they designed nanoparticles that can deliver three cancer drugs at a time. Delivering chemotherapy drugs in nanoparticle form could help reduce side effects by targeting the drugs directly to the tumors. In recent years, scientists have developed nanoparticles that deliver one or two chemotherapy drugs, but […]

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 Shows Nanoparticles in Consumer Products Can Damage DNA

April 9, 2014

2 Comments

Using high-speed screening technology to analyze DNA, a newly published study found that nanoparticles commonly added to consumer products can significantly damage DNA. Thousands of consumer products — including cosmetics, sunscreens, and clothing — contain nanoparticles added by manufacturers to improve texture, kill microbes, or enhance shelf life, among other purposes. However, several studies have […]

MIT Researchers Reverse a Rare Liver Disorder in Mice

April 3, 2014

1 Comment

In a newly published study, MIT researchers show that a new gene-editing technique, known as CRISPR, can reverse a rare liver disorder caused by a single genetic mutation. Using a new gene-editing system based on bacterial proteins, MIT researchers have cured mice of a rare liver disorder caused by a single genetic mutation. The findings, […]

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 […]

Scientists Reveal 3D Structure of the Molecular Transporter TSPO

March 24, 2014

1 Comment

Scientists have revealed the 3D structure of the molecular transporter TSPO for the first time, opening the door to novel paths for the diagnosis and treatment of brain diseases. The word “cholesterol” is directly linked in most people’s minds with high-fat foods, worrying blood test results, and cardiovascular diseases. However, despite its bad reputation, cholesterol […]

Yale Researchers Identify a Key Link between Tumors and Healthy Tissue

March 21, 2014

2 Comments

Researchers from the Yale School of Medicine have discovered a key link between tumors and healthy tissue, revealing a potential mechanism used by cancer cells to recruit healthy cells to promote tumor growth. The delicate balance between development of normal tissue and tumors depends in part upon a key molecular switch within cells, Yale School […]

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 […]
