In recent years, a body of publications in the microbiology field has challenged all previous knowledge of how antibiotics kill bacteria. "A slew of papers came out studying this phenomenon, suggesting that there is a general mechanism of killing by antibiotics," said Kim Lewis, Northeastern University Distinguished Professor in the Department of Biology and director of Northeastern's Antimicrobial Discovery Center.

In a long-term study, Prof. Dr. Jürgen Margraf, Alexander von Humboldt Professor for Clinical Psychology and Psychotherapy at the RUB, investigated the psychological effects of plastic surgery on approximately 550 patients in cooperation with colleagues from the University of Basel. Patients demonstrated more enjoyment of life, satisfaction and self-esteem after their physical appearance had been surgically altered. The results of the world's largest ever study on this issue are reported by the researchers in the journal "Clinical Psychological Science".
Extensive shell fishing and sewerage discharge in river estuaries could have serious consequences for the rare Icelandic black-tailed godwits that feed there. But it is the males that are more likely to suffer, according to new research from the University of East Anglia.
Research published today in the journal Ecology and Evolution reveals very different winter feeding habits between the sexes.
Drinking just two cups of coffee a day is associated with the risk of low birth weight. Researchers at Sahlgrenska Academy, University of Gothenburg, Sweden, have conducted a study on 59,000 women in collaboration with the Norwegian Institute of Public Health.
Massachusetts General Hospital (MGH) investigators have described what may be a newly identified disease that appears to explain some cases of widespread chronic pain and other symptoms in children and young adults. Their report that will appear in the April issue of the journal Pediatrics, and has received early online release, finds that most of a group of young patients seen at the MGH for chronic, unexplained pain had test results indicating small-fiber polyneuropathy, a condition not previously reported in children.
Shenzhen, China, March 11, 2013- BGI Tech Solutions Co., Ltd., also referred to as "BGI Tech", introduced today its novel assembly solution for facilitating heterozygous genomes research. This marks another technological breakthrough for BGI in heterozygous genome assembly after the completed genome sequencing of oyster, diamondback moth and pear.
Two University of Colorado Cancer Center studies show that the protein receptor Mer is overexpressed in many leukemias, and that inhibition of this Mer receptor results in the death of leukemia cells – without affecting surrounding, healthy cells.
The first study, published today in the journal Oncogene, worked with acute myeloid leukemia (AML), for which current chemotherapies offer a cure rate of only about 55 percent.
PHILADELPHIA — A new immunoassay that tests for the presence of three biomarkers appears to be a valid screening method for the early detection of malignant kidney cancer, according to data published in Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research.
Philadelphia, PA, March 11, 2013 – Once the initial episode of influenza has passed, the chronic effects tend to be overlooked. The results of a new study indicate that the cytokine interleukin-22 (IL-22) plays a critical role in normal lung repair following influenza infection. This study is published in the April 2013 issue of the American Journal of Pathology.
A new study has found that women who take aspirin have a reduced risk of developing melanoma—and that the longer they take it, the lower the risk. The findings suggest that aspirin's anti-inflammatory effects may help protect against this type of skin cancer. The study is published early online in CANCER, a peer-reviewed journal of the American Cancer Society.
Like nearly 4.6 million Americans, ancient hunter-gatherers also suffered from clogged arteries, revealing that the plaque build-up causing blood clots, heart attacks and strokes is not just a result of fatty diets or couch potato habits, according to new research in the journal The Lancet.
The researchers performed CT scans of 137 mummies from across four continents and found artery plaque in every single population studied, from preagricultual hunter-gatherers in the Aleutian Islands to the ancient Puebloans of southwestern United States.
Protein activity is strictly regulated. Incorrect or poor protein regulation can lead to uncontrolled growth and thus cancer or chronic inflammation. Members of the Institute of Veterinary Biochemistry and Molecular Biology from the University of Zurich have identified enzymes that can regulate the activity of medically important proteins. Their discovery enables these proteins to be manipulated very selectively, opening up new treatment methods for inflammations and cancer.
The risk of cardiovascular sudden death was very small and only about 30% of the incidence were due to diseases that could be reliably detected by pre-participation screening, even with 12-lead ECGs, according to research in a U.S. high school athlete population presented March 10 at the American College of Cardiology (ACC) Scientific Sessions.
The first multicenter study of hybrid revascularization shows that the emerging procedure for treating coronary artery disease has a similar rate of major adverse events in the first year, compared with percutaneous intervention (stenting).
SAN FRANCISCO – Can the length of strands of DNA in patients with heart disease predict their life expectancy?
Researchers from the Intermountain Heart Institute at Intermountain Medical Center in Salt Lake City, who studied the DNA of more that 3,500 patients with heart disease, say yes it can.
