New research by a Northeastern infectious disease modeling expert has linked a person's risk of contracting Zika in the U.S. to time spent outdoors. The findings could impact how communities address the spread of the virus.
Scientists discover several alterations in this cellular process with implications in cancer by analyzing samples from more than 4,000 patients.
Plant-pollinator relationships are vital to our natural and agricultural ecosystems, with an incredible amount of food crops worldwide dependent on plant-pollinator interaction success. But the advancement of climate change is disrupting plant-pollinator relationships. A special issue of Applications in Plant Sciences -- Studying Plant-Pollinator Interactions Facing Climate Change and Changing Environments -- explores the creative methods being used by researchers to study the effects of climate change on plant-pollinator relationships.
Many research groups have explored human adaptation to high altitude living among three major far-flung global populations: Tibetans, Ethiopians and Peruvians. But few have simultaneously explored the other extreme---maladaptation----in the form of chronic mountain sickness (CMS). Now, in the largest whole genome study of its kind, an international research team led by University of California San Diego's Chairman of Pediatrics, Dr. Gabriel Haddad, has expanded on their recent study of understanding both adaptation extremes in a Peruvian population.
Multiple sclerosis can be inhibited or reversed using a novel gene therapy technique that stops the disease's immune response in mouse models, University of Florida Health researchers have found.
Inspired by the Labyrinth of Greek mythology, a new chip etched with fluid channels sends blood samples through a hydrodynamic maze to separate out rare circulating cancer cells into a relatively clean stream for analysis. It is already in use in a breast cancer clinical trial.
Woody vegetation, such as trees and shrubs, has increased dramatically in Ozark grasslands over the past 75 years, according to a study published this week in the journal Landscape Ecology. If these ecosystems continue to favor woody vegetation, will it be possible to maintain open grasslands for the foreseeable future?
Chronic tissue inflammation resulting from obesity is an underlying cause of insulin resistance and type 2 diabetes. But the mechanism by which this occurs has remained cloaked, until now. In a paper, published in the journal Cell, University of California San Diego School of Medicine researchers identified exosomes -- extremely small vesicles or sacs secreted from most cell types -- as the missing link.
Human activities could change the pace of evolution, similar to what occurred 66 million years ago when a giant asteroid wiped out the dinosaurs, leaving modern birds as their only descendants. That's one conclusion drawn by the authors of a new study published in Systematic Biology.
Checkpoint inhibitor-based immunotherapy has been shown to be very effective in recurrent and metastatic head and neck cancer but only in a minority of patients. University of California San Diego School of Medicine researchers may have found a way to double down on immunotherapy's effectiveness.
