Understanding tomato plant metabolism for sustainable production
Historically, crops have been domesticated without limiting their access to nutrients or water. Since these varieties did not need efficient nutrient absorption and distribution mechanisms, they are poorly adapted to a sustainable agricultural system which limits the need for excess fertiliser. Drs Laura Carrillo and Joaquin Medina of the Centre of Biotechnology and Genomics (CBGP) in Madrid, Spain, investigated the […]
Green cleaning of heavy metals in water
Many anthropogenic activities have resulted in pollution of water with heavy metals, and pose a huge health risk for humans and animals. Some plants, however, can extract and accumulate these metals from soil and water without any toxic effects. Plant flavonoids are compounds that have the chemical ability to bind to heavy metals. Recent work by Dr Robert Luckay and […]
Blotches and spots: Understanding blemishes of faba bean
Over the last decade, grain legumes such as faba beans have been cultivated widely in the Nordic and Baltic countries. Faba bean is the world’s second-highest grain-yielding legume, yet the occurrence and spread of specific diseases of faba bean grown in Europe have not been studied in great detail. Dr Biruta Bankina and colleagues Dāvids Fridmanis, Gunita Bimšteine, Jānis Kaņeps, […]
Rethinking the Tree of Life with new tools
Professor Sung-Hou Kim and his colleagues from the University of California, Berkeley, have applied a new way of thinking to the Tree of Life, a concept that has been around since Darwin’s time. Drawing from their collective expertise, they applied an Information Theory-based non-alignment method to compare whole-proteome sequences, the protein sequences coded by all genes of each organism. Their […]
The Platform: A novel non-invasive fish monitoring method
Estuary environments are incredibly variable, both spatially and temporally, which can make fish monitoring using traditional sampling gear difficult. Dr Joseph Merz, of Cramer Fish Sciences, has developed a new non-invasive sampling gear for this purpose. The Single-Platform Aquatic Species and Habitat Sampling System (or The Platform) is able to monitor fish communities and their habitat interactions across various habitat […]
Antibiotic resistance in enterobacteria from pigs
Antibiotic resistance is a global threat affecting humans, pets, livestock and plants. As antibiotic usage to prevent infections is commonplace in livestock farming, there is a significant pressure to adopt alternative farming practices. Dr Dominic Poulin-Laprade and her colleagues at Agriculture and Agri-Food Canada and at the Canadian Food Inspection Agency, investigated how antibiotic-free farming practices affected the presence of […]
Protecting bottlenose dolphins from coastal construction
Professor Ann Weaver of Good-Natured Statistics Consulting, USA, has studied dolphins living free at sea for 20 years. Her numerous scientific discoveries about dolphin behaviour yield ample evidence of intelligence and of sophisticated social behaviour at sea. Drawing from many years of intensive studies in primates, she undertook an impressive 18-year ethological study of the social behaviour and impact of […]
Moisture regulation in finger pad ridges can ensure optimal grip
The ridges on the pads of our fingers, and the fingerprints we produce, have several benefits, including identification purposes. However, this was not the evolutionary purpose of ridged skin on the finger pad, and it is more likely to have evolved to optimise grip and touch. Professor Gun-Sik Park, Seoul National University, has explored how the finger pad has its […]
Cilia, asymmetry, and genetic disease
The length and movement of motile cilia – microscopic hair-like organelles on the outside of our cells – have a remarkable effect on the asymmetric development of embryos, allowing organs to grow in the correct places in our bodies. Dr Susana Lopes and her team at the LYSOCIL project are investigating rare genetic diseases affecting the cilia, and how these […]
Integrative plant responses: How seagrasses adjust to light
The shallow coastal waters that house tropical seagrass meadows are often highly illuminated. In the Caribbean, the main habitat builder is the species Thalassia testudinum, characterised by a leaf physiology adapted to shade. Dense canopies allow the seagrass to survive in such environments, but depth colonisation requires canopy and underground mass adjustments. These integrative plant responses are essential to adjusting […]
