Into the deep: understanding swordfish eco-physiology
Cold-blooded vertebrates, such as fish, are extremely susceptible to changes in the temperature of their surroundings. Yet one successful ocean predator, the swordfish, migrates from tropical to temperate seas, and dives daily from warm surface waters to cooler depths, with seeming ease. Drs Diego Bernal and Chugey Sepulveda of the University of Massachusetts Dartmouth and the Pfleger Institute of Environmental […]
Open-source bioinformatic solutions for ‘Big Data’ analysis
Drs Tim Griffin and Pratik Jagtap along with the Galaxy-P team from the University of Minnesota are working to develop workflows on an open source platform for the analysis of multi-omic data. They are currently focusing on using a Galaxy-based framework to investigate the integration of genomic datasets with mass spectrometry-based ‘omics’ data. But in the long term, they aim […]
Capturing images and data before the slides degrade into uselessness
Microscopic and enigmatic, the tardigrades are little known to science. However, their remarkable ability to enter suspended animation and withstand extreme conditions may support important medical advances. Prof Carl Johansson of Fresno City College, California, and Dr Lynn Kimsey of the Bohart Museum at UC Davis are documenting the amazing diversity of these secretive animals, and at the same time […]
Unravelling the signalling cues controlling vertebrate reproductive behaviour
How do vertebrate brains integrate information from external social cues and internal physiological states to produce appropriate behaviours? This is one of the big questions that Dr Karen Maruska and her research team at Louisiana State University (LSU) are striving to answer. Dr Maruska leads a research group that uses fish models to investigate how animals process and translate multisensory […]
Novel 3D microscope provides unprecedented moving images of biological processes
Dr Chunqiang Li and his team of the University of Texas at El Paso have developed a novel three-dimensional (3D) optical microscope that uses a spectrally shaped pulse laser. Whilst most prior microscopes used scanning to achieve high speed 2D imaging, Dr Li’s approach obtains the z-position from a technique called ‘temporal focusing’ that use ‘diffraction’ rings and clever mathematics […]
Energising life on earth: the third way
Almost all living organisms on earth get their energy, ultimately, from the sun. Energy is fixed in carbohydrates by plants and cyanobacteria during photosynthesis, then both animals and plants release it by breaking down those carbohydrates. Until now, only two main routes of carbohydrate breakdown were thought to be present in cyanobacteria and plants. However, Dr Kirstin Gutekunst, of Christian-Albrechts-University […]
Unlocking the chemical secrets of microbial conversations
Dr Matt Traxler of the University of California, Berkeley, is changing the way we study microbes. Gone are the days of thinking about a single species in a pure culture in the lab – Traxler and his team of graduate students and postdocs are developing a version of mass spectrometry which promises to allow single microbial cells, and their interactions […]
Florida’s Archbold Biological Station gives online access to unusual natural history collection
The Archbold Biological Station, a world-renowned ecological field station based in Florida, USA, is uploading its natural history collection onto the Internet for the first time. The diverse collection, containing 270,000 specimens of more than 10,000 species will provide researchers and students around the world, with access to this rich source of ecological data. This highly collaborative project, which involves […]
A sustainable approach to environmental management
Ten faculty members from the University of South Dakota and eleven undergraduate students from across the United States including Puerto Rico, came together through the Sustainable RIVER (Remediating InVasives to Encourage Resilience) program to study how a complex suite of historical and contemporary factors affect the current functioning and management of the Upper Missouri River. Most of society’s grand challenges […]
From beer to brains: how yeast molecular genetics prove the importance of introns
Scientific discoveries often come from the most unlikely of places, and Dr Tracy Johnson’s work is no exception. Using a yeast system typically used to make beer or bread, Dr Johnson and her team at UCLA have uncovered important genetic findings that could highlight the importance of intron retention during gene expression. Her research looks at the science of gene […]
