Seeing the Action: Novel Device Images Minute Forces, Actions Involved in Cell Membrane Hemifusion

May 26, 2015 — Researchers have developed a novel device to image the minute forces and actions involved in cell membrane hemifusion. To capture real time data on the behavior of cell membranes during hemifusion, ... read more

De Novo Assembly of a Haplotype-Resolved Diploid Genome Revealed

May 25, 2015 — The most complete haploid-resolved diploid genome sequence has been revealed by scientists based on de novo assembly with NGS technology. The pipeline developed lays the foundation for de novo ... read more

May 25, 2015 — A team of scientists has identified a set of genes that control stem cell production in the tomato. Mutations in these genes explain the origin of mammoth beefsteak tomatoes. More importantly, the ... read more

May 25, 2015 — Diabetes is the fastest growing metabolic disease in the world. A new study has shown that traditional Aboriginal and Indian plant extracts could be used to manage the disease and may also have ... read more

May 25, 2015 — Madagascar is home to extraordinary biodiversity, but in the past few decades, the island's forests and associated biodiversity have been under greater attack than ever. Rapid deforestation is ... read more

Beyond Average: New Platforms Genetically Barcode Tens of Thousands of Cells at a Time

May 21, 2015 — Two separate research teams have developed high-throughput techniques to quickly, easily and inexpensively give every individual cell in a sample a unique genetic barcode. This allows scientists to ... read more

May 21, 2015 — Scientists have moved a step closer to identifying the nanostructure of cellulose -- the basic structural component of plant cell walls. The insights could pave the way for more disease resistant ... read more

May 21, 2015 — Receptors carrying built-in decoys are the latest discovery in the evolutionary battle between plants and pathogens. The decoy domains within the receptor detect pathogens and raise the cell's ... read more

Estuaries Protect Dungeness Crabs from Deadly Parasites

May 22, 2015 — Parasitic worms can pose a serious threat to the Dungeness crab, a commercially important fishery species found along the west coast of North America. The worms are thought to have caused or ... read more

May 21, 2015 — Bacteria that live in the guts of cicadas have split into many separate but interdependent species in a strange evolutionary phenomenon that leaves them reliant on a bloated genome, a new paper has ... read more

May 21, 2015 — A gene responsible for sex determination in mosquitoes that can transmit yellow fever, dengue, and chikungunya viruses has been identified by researchers. Only female mosquitoes bite because they ... read more

May 21, 2015 — A multinational team of researchers who spent three and a half years sampling the ocean's sunlit upper layers aboard the schooner Tara unveil the first officially reported global analyses of the ... read more

May 21, 2015 — Ocean microbes are vital to the Earth's ecosystems, and their interactions with ocean viruses can have dramatic effects on processes ranging from oxygen production to food supply. Marine ... read more

May 21, 2015 — Researchers have developed a model to assess how dams affect the viability of sea-run fish species that need to pass dams as they use both fresh and marine waters during their lifetimes. The aim is ... read more

May 21, 2015 — An extract from the thunder god vine, which has a long history of use in traditional Chinese medicine, reduces food intake and causes up to a 45 percent decrease in body weight in obese mice. The ... read more

May 21, 2015 — A comprehensive genetic study of American black bears throughout North America has been completed by scientists. They discovered that black bears in Alaska are more closely related to bears in the ... read more

May 21, 2015 — A certain type of soil bacteria can use their social behavior of outer membrane exchange to repair damaged cells and improve the fitness of the bacteria population as a whole, new research ... read more

May 21, 2015 — Scientists have discovered a new species of fossil in England -- and identified it as an ancient parasitic intruder. The fossil species -- a 'tongue worm', which has a worm-like body and a ... read more

May 21, 2015 — Dogs' special relationship to humans may go back 27,000 to 40,000 years, according to genomic analysis of an ancient Taimyr wolf bone. Earlier genome-based estimates have suggested that the ... read more

May 21, 2015 — Antimicrobial resistance in bacteria poses a global threat to public health. Common antibiotics are often ineffective in treating infectious diseases because pathogens acquire resistance genes. These ... read more
