Universal flu vaccine protects against 6 influenza viruses in mice
15/01/2020 - A novel nanoparticle vaccine that combines two major influenza proteins is effective in providing broad, long-lasting protection against influenza virus in mice, showing promise as a universal flu...
How bacterial evolution of antibiotic arsenals is providing new drug blueprints
15/01/2020 - Scientists have taken their cue from nature to provide new options for drug designers seeking to hold back the global threat of antimicrobial resistance. The scientists have blueprinted how two...
Stem cell studies offer hope for childhood neurological condition
09/01/2020 - Two new studies report progress in using stem cells to develop new therapies for Pelizaeus-Merzbacher disease (PMD), a rare genetic condition affecting boys that can be fatal before 10 years of age.
Stem cell transplants used to grow fully functional lungs in mice
09/01/2020 - Researchers have used transplanted stem cells to grow lungs in mice. Findings could lead to new options for lung transplant patients.
Saccharin derivatives give cancer cells a not-so-sweet surprise
09/01/2020 - Saccharin received a bad rap after studies in the 1970s linked consumption of large amounts of the artificial sweetener to bladder cancer in laboratory rats. Later, research revealed that these...
Mutations linked to familial pancreatic cancer
09/01/2020 - A new study finds genetic mutations associated with hereditary forms of pancreatic cancer and mechanism by which these mutations may contribute to the development of tumors.
How common genetic mutation drives cancer
09/01/2020 - A new, multicenter study has determined how a single mutation in splicing factor 3b subunit 1 (SF3B1), the most frequently mutated splicing factor gene, drives the formation of many cancers.
Brain tumor organoids may be key to time-sensitive treatments for glioblastomas
09/01/2020 - Lab-grown brain organoids developed from a patient's own glioblastoma, the most aggressive and common form of brain cancer, may hold the answers on how to best treat it. A new study showed how...
Cheers! Maxwell's electromagnetism extended to smaller scales
09/01/2020 - More than one hundred and fifty years have passed since the publication of James Clerk Maxwell's "A Dynamical Theory of the Electromagnetic Field" (1865). What would our lives be...
Tiny devices made of DNA detect cancer with fewer false alarms
09/01/2020 - A new cancer-detecting tool uses tiny circuits made of DNA to identify cancer cells by the molecular signature on their surface. The circuits work by attaching to the outside of a cell and analyzing...
Collaborative Conservation Approach for Endangered Reef Fish Yields Dramatic Results
09/01/2020 - A new study from researchers at the Scripps Institution of Oceanography at the University of California San Diego has documented a successful recovery effort among Nassau Grouper populations in the...
New drug target for glioblastoma
09/01/2020 - A new international study has identified a new drug target for treating glioblastoma. This target is part of a never-before defined cellular pathway found to contribute to the spread and...
Treatment for 'low T' could someday come from a single skin cell
09/01/2020 - Researchers have successfully grown human, testosterone-producing cells in the lab, paving the way to someday treat low testosterone with personalized replacement cells.
Human heart cells are altered by spaceflight, but return to (mostly) normal on Earth
09/01/2020 - Heart muscle cells derived from stem cells show remarkable adaptability to their environment during and after spaceflight, according to a new study. The researchers examined cell-level cardiac...
An atomic view of the trigger for the heartbeat
09/01/2020 - Tiny pores in heart cells generate electrical signals to initiate each heart beat. Structural studies of these channels provide details on their functions, and also on their malfunction due to...
Most patients willing to share medical records for research purposes
09/01/2020 - Researchers report most patients are willing to share medical records for research purposes, with a few caveats.
Virtual review of cancer clinical trial treatment options quicker than conventional method
09/01/2020 - Using virtual, cloud-based, interconnected computing techniques applied to 51,000 variables, researchers reduced the time needed to assess a cancer patient's tumor profile and suitability for...
Genetic study provides most comprehensive map of risk to date of breast cancer risk
09/01/2020 - A major international study of the genetics of breast cancer has identified more than 350 DNA 'errors' that increase an individual's risk of developing the disease. The scientists...
