Gut flora may lead to better diagnosis tool for liver diseasePrimary sclerosing cholangitis, also known as PSC, is a liver disease with no effective medical treatment. Liver transplantation is the only proven long-term treatment of PSC, although only a fraction of individuals with PSC will ultimately require it. The vast majority of patients with PSC also have inflammatory bowel disease (Crohn's disease or ulcerative colitis), possibly implying that the intestine plays a role in the origin of this PSC. Researchers from VIB, UZ Leuven and KU Leuven now describe for the first time how changes in the intestinal microbiota are specifically associated with this disease. | |

![]() | Telomere length in circulating blood cells does not predict asymptomatic atherosclerosisCardiovascular disease (CVD) is the main cause of death in the world, killing 17.5 million people every year according to WHO figures. Prevention strategies based on risk prediction are now a top public health priority, and there is great interest in developing new biomarkers of cardiovascular risk that allow a more accurate risk predication than classical risk factors such as high cholesterol, smoking, physical inactivity, and high blood pressure. One possible biomarker is telomere length, but a new study suggests that leukocyte telomere length (LTL) in circulating blood does not effectively predict CVD risk in individuals without disease symptoms. The results of the study, conducted at the Centro Nacional de Investigaciones Cardiovasculares Carlos III (CNIC) and led by Drs. Valentín Fuster and Vicente Andrés, are published in The Journal of the American College of Cardiology (JACC). |

Chloride 'switch' turns on membrane formationChloride plays a key role in the formation of the basement membrane, a suprastructure on the outside of cells that undergirds and guides the function of most of the tissues of the body. | |
![]() | Study decodes genetic circuitry for bacterial spore formationA team led by Rice University bioengineering researchers has decoded the mechanism that some bacteria use to make life-or-death decisions during extremely tough times. |
![]() | Your dog doesn't trust you when you're angryBYU psychology professor Ross Flom recently conducted a study to find out just how well dogs understand humans, specifically human emotion. |
![]() | Migratory fish species suffering severe population lossIn the past three decades global catches of sturgeons and paddlefishes have dropped by over 99 per cent, documenting severe population losses, according to a new WWF report. |
New seed 'flaming' technique to help with minesite rehabResearchers at The University of Western Australia have invented a new technique for 'flaming' wild seeds that could allow them to be used more easily in replanting large tracts of land such as reclaimed mine sites. | |
![]() | The protein that assesses distancesA protein of the ISWI family (Imitation Switch, or nucleosome remodelling motors) is endowed with a special property: despite having no organ of sense it is nonetheless able to assess the length of DNA strands. A study just published in the Journal of Statistical Mechanics: Theory and Experiment and carried out by SISSA, the MAX Planck Institute and the NIH has discovered how it works. |
![]() | ESF lists top 10 new species for 2016A hominin in the same genus as humans and an ape nicknamed "Laia" that might provide clues to the origin of humans are among the discoveries identified by the SUNY College of Environmental Science and Forestry (ESF) as the Top 10 New Species of 2016. |
![]() | Drone captures shark feeding frenzy on whaleA drone has captured a bloody feeding frenzy by around 70 tiger sharks on a dead whale, turning the pristine waters of the aptly named Shark Bay in Australia red. |
![]() | India captures endangered lions after fatal attacksThirteen endangered Asiatic lions that only live in a forest in western India have been caught and caged after three villagers were killed in recent months, a wildlife official said Monday. |
![]() | Evaluating the cost of accuracy of sequencing approachesResearchers use synthetic and natural microbial lake communities to compare the microbial community profiles generated from high throughput short-read sequencing and high throughput long-read sequencing approaches. |
![]() | A peachy defense system for seedsETH chemists are developing a new coating method to protect seeds from being eaten by insects. In doing so, they have drawn inspiration from the humble peach and a few of its peers. |
![]() | New research confirms continued, unabated and large-scale amphibian declinesNew U.S. Geological Survey-led research suggests that even though amphibians are severely declining worldwide, there is no smoking gun - and thus no simple solution - to halting or reversing these declines. |
![]() | A rallying call for microbiome science national data managementMassive amounts of data require infrastructure to manage and store the information in a manner than can be easily accessed for use. While technologies have scaled to allow researchers to sequence and annotate communities of microorganisms within an environment,(its "microbiome"), on an ever-increasing scale, the data management aspect has not been developed in parallel. |
Catching rice-invading snails in the actCommonly available eco-friendly plants and materials can be used to trap rice-crop-invading snails in place of chemicals, according to new research in the Pertanika Journal of Tropical Agricultural Science. | |
Cities try different tactics to regulate noiseIf you live in Waco, Texas, your neighbor maneuvering a gas lawn mower in the middle of the night likely wouldn't violate the decibel limit, which is eight times louder than the typical nighttime limit in the United States. | |
![]() | Why fruit cracking differs among sweet cherry varietiesSweet cherries are susceptible to a condition called "cracking", in which the skin of the fruit is strained, causing fractures or "cracks". The condition, which limits marketability of the fruit, may be a result of factors such as excessive water uptake or weak fruit skins. In a new study published in the Journal of the American Society for Horticultural Science (March 2016) researchers examined the mechanical properties of different cherry cultivars to determine how these properties impact skin cracking. |
