New mathematical model shows how diversity speeds consensus
15/01/2020 - Scientific literature abounds with examples of ways in which member diversity can benefit a group -- whether spider colonies' ability to forage or an industrial company's financial...
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...
Scientists improve yield predictions based on seedling data
15/01/2020 - A doctor diagnosing a 50-year-old patient based on a blood test taken during the patient's infancy would be unthinkable. Anecdotally speaking, however, that's what scientists have done with...
How the rice blast fungus 'eats' its own cell wall to launch an attack
15/01/2020 - In response to environmental changes and nutrient starvation, cells are known to undergo extreme alterations. This includes switching from one type to another ('differentiation') and...
New study reveals the origin of complex malaria infections
15/01/2020 - New technology employing single cell genome sequencing of the parasite that causes malaria has yielded some surprising results and helps pave the way for possible new intervention strategies for this...
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...
'Bilingual' molecule connects two basic codes for life
15/01/2020 - The nucleic acids of DNA encode genetic information, while the amino acids of proteins contain the code to turn that information into structures and functions. Together, they provide the two...
Taking one for the team: How bacteria self-destruct to fight viral infections
15/01/2020 - Researchers have discovered how a new immune system works to protect bacteria from phages, viruses that infect bacteria -- new information that could be leveraged to improve treatment of...
Leviathan polymer brush made with E. coli holds bacteria at bay
15/01/2020 - A lab accident produced a monster of a polymer brush, an emerging biocompatible material that staves off bacteria while coating and lubricating.
A controlled phage therapy can target drug-resistant bacteria while sidestepping potential unintended consequences
15/01/2020 - The fight against drug-resistant pathogens remains an intense one. While the Centers for Disease Control's (CDC) 2019 'biggest threats' report reveals an overall decrease in...
Dynamic interplay between genome and environment in pearl oysters
15/01/2020 - Researchers have, using genome-wide genetic data from specimens collected across the western Pacific, elucidated how pearl oyster populations vary genetically and geographically.
Highlighting women's achievements makes them want to be the boss, research shows
15/01/2020 - Highlighting female achievements in the workplace makes capable women significantly more likely to want to be the boss, a study shows.
Stem cell researchers reactivate 'back-up genes' in the lab
09/01/2020 - Scientists have unraveled parts of a mechanism that may one day help to treat Rett syndrome and other genetic disorders linked to the X chromosome.
Lymphatic system found to play key role in hair regeneration
09/01/2020 - To grow new hair, stem cells throughout the skin must work in sync. Researchers have discovered the molecular communication tool, part of the lymphatic system, that the cells use to synchronize their...
Transition to exhaustion: Clues for cancer immunotherapy
09/01/2020 - Research on immune cells 'exhausted' by chronic viral infection provides clues on how to refine cancer immunotherapy. The Immunity paper defines a transitional stage in between stem-like...
Nunavik Inuit are genetically unique
09/01/2020 - A new study has found that an Inuit population in Canada's Arctic are genetically distinct from any known group, and certain genetic variants are correlated with brain aneurysm.

09/01/2020 - In the prospective TAILORx trial, 93% of women with hormone-sensitive, HER2-negative, axillary node-negative breast cancer and a high Recurrence Score 26-100 were estimated to be cancer-free at five...
Genetics may determine who benefits from broccoli's effects on kidney health
09/01/2020 - Deletion of the gene that codes for an enzyme called GSTM1 increased kidney injury in mice with hypertension and kidney disease, but supplementing the diet with broccoli powder lessened kidney injury...
A tech jewel: Converting graphene into diamond film
09/01/2020 - Can two layers of the ''king of the wonder materials,'' i.e. graphene, be linked and converted to the thinnest diamond-like material, the ''king of the...
Researchers build a particle accelerator that fits on a chip
09/01/2020 - For the first time, scientists have created a silicon chip that can accelerate electrons -- albeit at a fraction of the velocity of the most massive accelerators -- using an infrared laser to...
