![]() | US regulators clear path for genetically modified salmonU.S. regulators on Friday gave the green light to salmon genetically modified to grow about twice as fast as normal, but the company behind it may face legal challenges before the fish can be sold domestically. |
![]() | New species of stiletto snake capable of sideways strikes discovered in West AfricaFollowing a series of recent surveys in north-western Liberia and south-eastern Guinea, an international team of researchers found three stiletto snakes which were later identified as a species previously unknown to science. |
![]() | Illuminating the genomeThe CRISPR/Cas9 system has been causing ripples in the scientific community ever since its mechanisms were reported in 2012. Commonly referred to as a genome editing tool, many scientists have found different applications for the scissor-like properties of the Cas9-protein. Researchers from the Leibniz Institute of Plant Genetics and Crop Plant Research (IPK Gatersleben) have now found a way to utilise the RNA/protein complex in a slightly different way—as a cytogenetic torch. Other than in conventional in situ hybridisation, the new RNA-guided endonuclease—in situ labelling-tool (RGEN-ISL) no longer requires denaturation of the DNA. The new method therefore leaves the chromatin intact, enabling investigation of the structure of the sample. Moreover, RGEN-ISL can be combined with protein-detection methods and allows real-time visualisation of the labelling-process. Whilst initially developed for plant genomes, RGEN-ISL can be used in all organisms and shows to be a promising new tool in the field of chromosome biology. |
![]() | When a cell's 'fingerprint' can be a weapon against cancerA research team led by Nuno Barbosa Morais, group leader at Instituto de Medicina Molecular João Lobo Antunes (iMM) in Lisbon, computationally analysed the expression of marker genes that are associated with a "fingerprint" of cancer cells in thousands of tumors and revealed its therapeutic potential in the fight against cancer. The study published today in PLoS Computational Biology shows the types of tumors in which these genes are most active and identifies drugs that can selectively eliminate cells that carry that label. |
![]() | Researchers report two pathways that cells use to mend cancer-causing DNA damageDNA damage occurs in all cellular organisms. In human cells, it can be caused by the body's normal metabolic activities, by environmental factors or by chemotherapy. During the crucial phase when cells replicate their genetic content, they are susceptible to lesions – damaged sections of a DNA molecule. Common lesions known as DNA-protein cross-links (DPCs) can prevent the cell from replicating itself and may lead to genome instability, a cause of cancer and ageing. |

![]() | How birds become male or female, and occasionally bothThe highly unusual "semi-identical" Australian twins reported last week are the result of a rare event. It's thought the brother and sister (who have identical genes from their mother but not their father) developed from an egg fertilised by two different sperm at the same moment. |
![]() | Viruses interact socially with each other to evade the immune systemPilar Domingo, Ernesto Segredo, María Durán and Rafael Sanjuán from the Institute of Integrated Systems Biology (I²SysBio) have shown that viruses behave altruistically to avoid the immune system. This research, published on Monday in Nature Microbiology and carried out in the vesicular stomatitis virus (VSV), has potential applications in the development of antiviral and vaccine treatments. |

![]() | Fair Isle Bird Observatory—Watching the birdwatchersNote: This post was scheduled just as news came in that the Fair Isle Bird Observatory had been destroyed by fire on Sunday, 10th March 2019). Thankfully, nobody was injured in the fire. Plans are already afoot to rebuild, but that will take time and money. |
![]() | Scientists discover a potential strategy to treat influenza AA team of researchers from Scripps Research and Janssen Research & Development LLC has discovered an orally active small molecule that neutralizes influenza A group 1 viruses, the most common flu strains. Scientists uncovered the potential therapy in a large chemical library and optimized lead compounds to produce JNJ-4796. Now they have proven its effectiveness against influenza in mice. |
![]() | Anti-malarial shows promise in human clinical studyAn experimental drug, called DSM265, cured seven volunteers of a Plasmodium falciparum infection, a malaria parasite that is a major cause of morbidity and mortality worldwide. The goal of this research is to find a cure for malaria with a single dose, and ultimately, eradicate the parasite. The research is published March 11 in Antimicrobial Agents and Chemotherapy, a journal of the American Society for Microbiology. |

Sechenov First Moscow State Medical University together with their Russian colleagues studied the reaction of wheat plants to damage caused by pathogenic fungi. They examined the activation of enzymes involved in cell death induced in response to infection. The research results and enzyme classification were published in the International Journal of Molecular Sciences. |
![]() | Dog therapy: What I've learned overseeing 60 canine campus teamsThe interaction always played out the same way. I'd leave my office and make my way across campus in search of coffee, my dog Frances by my side, and I would be besieged by students who, for the most part, would ignore me and lose themselves in Frances. They would eventually look up with tear-filled eyes and say: "As much as I miss my parents, I miss my dog more." |
![]() | Sowing the seeds – The past, present and future of plant conservation at FFIYou have to fast-forward almost 80 years from the origins of Fauna & Flora International (FFI) before you find any formal acknowledgement of our interest in things botanical, but plant conservation was on our agenda long before 'Flora' featured in our actual name. |
