How these pretty weeds resist Roundup
Genome-wide scans identify the source of the common morning glory's resistance to the herbicide Roundup. Roundup is the most widely used agricultural chemical in history. But over the past two decades, a growing number of weed species have evolved resistance to Roundup's active ingredient, glyphosate. Research on the genetic basis of glyphosate resistance has focused largely on target-site resist

Fly model offers new approach to unraveling 'difficult' pathogen
Clostridium difficile, a bacterium known to cause symptoms from diarrhea to life-threatening colon damage, is part of a growing epidemic for the elderly and hospitalized patients. Biologists have now developed models of the common fruit fly to help develop novel therapies to fight the pathogen.

Combined drug treatment for lung cancer and secondary tumors
Researchers at Kanazawa University report in the Journal of Thoracic Oncology a promising novel approach for a combined treatment of the most common type of lung cancer and associated secondary cancers in the central nervous system. The approach lies in combining two cancer drugs, with one compensating for a resistance side effect of the other.

Understanding gut microbiota, one cell at a time
Summary: Waseda University scientists devised a novel single-cell genomic sequencing technique that enables detailed, functional analysis of uncultured bacteria and identified bacterial responders of dietary fiber inulin in mouse gut microbiota. This technique could be applied to predict the metabolic fermentation of dietary fibers based on the presence and ability of specific responders and be ex

Alaska's national forests contribute 48 million salmon a year to state's fishing industry
Alaska's Tongass and Chugach National Forests, which contain some of the world's largest remaining tracts of intact temperate rainforest, contribute an average of 48 million salmon a year to the state's commercial fishing industry, a new USDA Forest Service-led study has found. The average value of these "forest fish" when they are brought back to the dock is estimated at $88 million per year.

New method for monitoring residual disease after treatment in children with neuroblastoma
Neuroblastoma is a cancer that affects children, characterized by solid tumors that develop from immature nerve cells. Over 50% of patients with high-risk neuroblastoma experience tumor relapse/regrowth.A research group led by Professor NISHIMURA Noriyuki (Graduate School of Health Sciences, Kobe University) has developed a new method to monitor the residual disease after treatment in high-risk ne

BioNyt Videnskabens Verden (www.bionyt.dk) er Danmarks ældste populærvidenskabelige tidsskrift for naturvidenskab. Det er det eneste blad af sin art i Danmark, som er helliget international forskning inden for livsvidenskaberne.
Bladet bringer aktuelle, spændende forskningsnyheder inden for biologi, medicin og andre naturvidenskabelige områder som f.eks. klimaændringer, nanoteknologi, partikelfysik, astronomi, seksualitet, biologiske våben, ecstasy, evolutionsbiologi, kloning, fedme, søvnforskning, muligheden for liv på mars, influenzaepidemier, livets opståen osv.
Artiklerne roses for at gøre vanskeligt stof forståeligt, uden at den videnskabelige holdbarhed tabes.
