Antifreeze Protein Fights Frostbite

A new study from Yale University shows that a protein that protects ticks from freezing temperatures also prevents frostbite when introduced in mice. This is the first study to demonstrate the protein’s ability to boost frostbite resistance in an adult mammal. The research was published February 25 in the journal PLOS ONE. Several animal species, […]

Engineered Insulin Offers Better Diabetes Control

Engineers from MIT have developed insulin that can circulate in the bloodstream for hours, responding rapidly to changes in blood-sugar levels. For patients with diabetes, insulin is critical to maintaining good health and normal blood-sugar levels. However, it’s not an ideal solution because it can be difficult for patients to determine exactly how much insulin […]

Researchers Identify Link between Inflammation and Type 2 Diabetes

A newly published study led by Yale University reveals the molecular mechanism by which insulin normally inhibits production of glucose by the liver and why this process stops working in patients with type 2 diabetes, leading to hyperglycemia. The findings are published February 5 in the journal Cell. “In the study, we set out to […]

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 […]

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 […]

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 […]

Research Shows Molecular Decoys Help Overcome Drug Resistance

By using molecular fragments administered alongside antimicrobial agents, researchers at Brown University have shown that the efflux pumps are kept busy pumping out the fragments while the antimicrobial agents are able to stay inside the cell. Providence, Rhode Island – Brown University – Harmful bacteria have evolved some ingenious mechanisms to resist antibiotics. One of […]

Researchers Uncovered a Detectable Precancerous State in Blood

Two newly published studies detail the discovery of a precancerous state found in blood, paving the way for research that focuses on detection and prevention of blood cancers. Researchers from the Broad Institute of MIT and Harvard, Harvard Medical School, the Harvard Stem Cell Institute (HSCI), and Harvard-affiliated hospitals have uncovered an easily detectable, “premalignant” […]

New Algorithm Can Help Determine How to Treat Patients

Researchers from MIT, Harvard Medical School and the Einstein Medical Center in Philadelphia have developed a new algorithm that can, with high accuracy, determine whether a patient is suffering from emphysema or heart failure based on the concentration of carbon dioxide in a patient’s exhalations. Paramedics respond to a 911 call to find an elderly […]

Scientists Develop a Possible Alternative to Antibiotics

By engineering artificial nanoparticles made of lipids, scientists have developed a treatment for bacterial infections without using antibiotics. Scientists from the University of Bern have developed a novel substance for the treatment of severe bacterial infections without antibiotics, which would prevent the development of antibiotic resistance. Ever since the development of penicillin almost 90 years […]

New Approach Could Kill Tumor Cells in the Brain More Effectively

New research shows that delivering chemotherapy directly into the brain cavity may kill tumor cells in the brain more effectively and avoid side effects. Every year, about 100,000 Americans are diagnosed with brain tumors that have spread from elsewhere in the body. These tumors, known as metastases, are usually treated with surgery followed by chemotherapy, […]

Tick Protein Inspires New Class of Antibiotics

Scientists from Yale University have discovered that an antifreeze protein in ticks that kicks in during winter can also fights infection, possibly leading to a new class of antibiotics for humans. A protein in ticks that protects them against the cold could inspire a new class of antibiotics for humans, according to a Yale University […]

Research Shows Stimulant Use Increases by 30 Percent During the School Year

New research from Yale, NYU and the University of Wisconsin-Madison shows that students are 30% more likely to take a stimulant medication during the school year than they are to take one during the summer. The authors found that school-year increases in stimulant use are largest for children from socioeconomically advantaged families. Because many children […]

New Drug Delivery Capsule Can Deliver Drugs Directly into the Lining of the Digestive Tract

Researchers at Massachusetts General Hospital and MIT have developed a new drug-delivery capsule coated with tiny needles that can inject drugs directly into the lining of the stomach after the capsule is swallowed. Given a choice, most patients would prefer to take a drug orally instead of getting an injection. Unfortunately, many drugs, especially those […]

Research Shows Boost in Certain Amino Acids is Sign of Early Cancer

Based on an analysis of blood samples from 1,500 people participating in long-term health studies, biologists found that people with a surge in amino acids known as branched chain amino acids were far more likely to be diagnosed with pancreatic cancer within one to 10 years. Years before they show any other signs of disease, […]
