Indiana University Research: Rainbow Dyes Add Greater Precision in Fight Against 'Superbugs'

Bacillussubtilisandbullseye_creditYen-PangHsu_v2.jpg

A study reported Jan. 17 in the journal Science led by researchers at Indiana University and Harvard University is the first to reveal in extreme detail the operation of the biochemical clockwork that drives cellular division in bacteria. It is an important step forward in research on bacterial growth and could inform efforts to develop drugs that combat antibiotic-resistant bacteria.

Immune Cell Serves as an Essential Communications Link for Migrating Cells

Scientists at the University of Washington have discovered that macrophages, a common type of cell in the vertebrate immune system, can transmit messages between non-immune cells. Their paper, published online Feb. 16 in the journal Science, is the first reported instance of macrophages relaying messages over a long distance between non-immune cells.

Biochemical Tricks of the Hibernating Bear

WEB_JournalNews_-_Bear.jpg

Winter is in full swing, and many of us have fantasized about curling up in a warm cave and slumbering until the warmth of spring arrives, just like a bear. Bears have the ability to sleep away the harsh winter months when food is scarce. They can spend five to seven months in hibernation. During this time, bears do not eat, drink, excrete or exercise. Despite the length of inactivity, bears do not experience bone loss, muscle loss, heart complications or blood clots like humans do during extended bouts of inactivity.

'Resurrecting' Tiny Lake-Dwelling Animals to Study Evolutionary Responses to Pollution

A University of Michigan biologist combined the techniques of "resurrection ecology" with the study of dated lake sediments to examine evolutionary responses to heavy-metal contamination over the past 75 years.

Targeted Radiosurgery Better Than Whole-Brain Radiation for Treating Brain Tumors

Tumors that originate in other organs of the body and spread to the brain are known as metastatic brain tumors. According to the American Brain Tumor Association, this type of tumor is the most common in adults, affecting as many as 300,000 people each year. University of Missouri School of Medicine researchers compared two common postsurgical therapies for metastatic brain tumors and found that stereotactic radiosurgery can provide better outcomes for patients compared to whole-brain radiation.

Scientists Create Novel Model That Shows Progression From Normal Blood Cells to Leukemia

Mount Sinai researchers have created a novel model that shows the step-by-step progression from normal blood cells to leukemia and its precursor diseases, creating replicas of the stages of the disease to test the efficacy of therapeutic interventions at each stage, according to a study to be published in Cell Stem Cell. This research marked the first time scientists have been able to transplant leukemia from humans to a test tube and then into mice for study, a landmark feat that will allow for valuable research to help find therapies for blood cancer patients in the future.

Doctors Treat Deadly Cancerous Disorders with Gene-Guided, Targeted Therapy

KumarJCIinisght_petscan.jpg

Genomic testing of biopsies from patients with deadly, treatment-resistant cancerous blood syndromes called histiocytoses allowed doctors to identify genes fueling the ailments and use targeted molecular drugs to successfully treat them. Researchers report their data in Journal of Clinical Investigation Insight (JCI Insight). They recommend the regular use of comprehensive genomic profiling at diagnosis to positively impact clinical care,
