Aquaculture, or fish farming, is one of the fastest growing sectors of agriculture in the world today. However, farmers in the United States who wish to capitalize on this momentum face regulatory hurdles when dealing with fish waste. But new research shows that a simple, organic system can clean aquaculture wastewater effectively and inexpensively. Researchers built bioreactors—long containers filled with wood chips—to treat wastewater from a fully operational recirculating aquaculture system in West Virginia. The idea is simple: water from the fish tank enters the bioreactor at one end, flows through the wood chips, and exits through a pipe at the other end. Along the way, solids settle out and bacteria housed in the wood chips remove nitrogen, a regulated pollutant.

Researchers from Turku Centre for Biotechnology have observed that a protein called SHANK prevents the spread of breast cancer cells to the surrounding tissue. The SHANK protein has been previously studied only in the central nervous system, and it is known that its absence or gene mutations are related to autism. The research was conducted at Turku Centre for Biotechnology. The novel discovery impinges upon the protein called SHANK which has been intensively studied in several processes in central nervous system and gene mutations in SHANK are linked to autism. The same factors can regulate cell shape and adhesion in very different cell types. Our results revealed that gene mutations in SHANK, found in autistic patients, impair SHANKs ability to prevent the adherence of both neurons and breast cancer cells. This once again demonstrates the power of basic research in facilitating our understanding of several human diseases, rejoices Academy professor Johanna Ivaska.

People with social anxiety avoid situations in which they are exposed to judgment by others. Those affected also lead a withdrawn life and maintain contact above all on the Internet. Around one in ten people is affected by this anxiety disorder over the course of their life. Researchers at the University of Bonn have now found evidence for a gene that is believed to be linked to the illness. It encodes a serotonin transporter in the brain. Interestingly, this messenger suppresses feelings of anxiety and depressiveness. The scientists want to investigate this cause more precisely and are thus looking for more study participants. The results will be published in the journal “Psychiatric Genetics”.

Do anogenital lesions of HIV-positive men that clinically appear as benign warts contain areas of dysplasia, and if so, what are the virological characteristics of those lesions? Findings  In this case series, a high proportion of anogenital warts contained areas of high-grade and low-grade dysplasia or even invasive cancer. Some of these lesions contained only low-risk-HPV types. Dysplasia was absent in all lesions of immunocompetent control patients.

Human papillomavirus (HPV)-induced anogenital lesions are very frequent in men who have sex with men (MSM) who are HIV-positive (HIV+). Anogenital warts (AGWs) are considered benign lesions caused by low-risk HPV-types, whereas anogenital dysplasias are potential cancer precursors associated with high-risk HPV-types. Both types of lesions can usually be distinguished clinically.

A marine science iBook entitled “Harmful Algal Blooms” has been developed as part of NUI Galway’s contribution to an EU-funded European research project Sea Change. The project aims to raise European citizens’ awareness of the ocean’s influence on us and our influence on the ocean, or “Ocean Literacy”. The iBook will be launched by Professor Colin Brown, Director of the Ryan Institute for Environmental, Marine and Energy Research on Monday 13 March at the National University of Ireland, Galway.
