Professor Thomas Feuerstein | A Paradox Explained: Why a Super Selective β1-blocker Works in Acute Heart Failure
β1-adrenoceptors are found in the heart where they bind neurotransmitters/hormones such as noradrenaline and adrenaline. The binding of these β1-adrenoceptors agonists activates a response in the heart muscle that helps...

Dr Daisuke Minakata – Sunshine and Organic Molecules in Water
Organic molecules dissolved in rivers, lakes, seas and oceans are essential to plant and animal life. Some of these molecules are also degraded and enter a complex cycle of carbon, nitrogen and sulphur containing compounds. Surprisingly, scientists currently have a limited understanding of the fate of these molecules. Dr Daisuke Minakata and his colleagues from Michigan Technological University are involved in an ambitious programme to overcome this critical knowledge gap.

SCI-COMM CORNER
SciComm Corner – Can science communicators help to protect endangered species?
Over the past few decades, the pace at which animal species are becoming extinct has accelerated considerably. Estimates by the International Union for Conservation of Nature (IUCN) suggest that over 16,000 animal species are now at risk, while in 2007 the red list of endangered animals included 7,851 species.
SciComm Corner – Three things to consider when communicating science to people with sensory impairments
While there have been numerous efforts to improve the quality of life of people with sensory impairments, there are still many instances in which visual or hearing impairments can limit one’s experiences. This includes the communication of information online or through other media platforms.

Professor Christian Laforsch | Professor Andreas Greiner – Microplastics: Solutions for a Persistent Pollutant
Plastics have revolutionised human existence. Medicine, technology, agriculture and construction all rely on highly durable plastic materials. However, the enduring legacy of plastics extends far beyond our cities and towns. Everywhere we look, from the deepest parts of the oceans to alpine glaciers, we find tiny fragments called microplastics. Recently, the collaborative research centre, ‘CRC 1357 Microplastic’, at the University of Bayreuth was granted a second funding phase by the German Science Foundation, to continue their intensive research into microplastics. The CRC 1357 team studies the formation and behaviour of microplastics in the environment and their long-term effects on soils, plants, organisms, and ecosystem processes. Through their research, the University of Bayreuth will be able to contribute to ground-breaking recommendations for policy-makers, industry and society.

Dr Kay Cooksey | Developing Intelligent Packaging Solutions to Prevent Foodborne Illnesses
Many of us avoid foods that contain ingredients we haven’t heard of. However, many of these chemicals are beneficial because they prevent the growth of bacteria that cause foodborne illnesses. Although food quality standards have improved dramatically, outbreaks of foodborne illnesses are still common. Luckily, we have one line of defence to exploit: antibacterial food packaging. Dr Kay Cooksey of Clemson University is leading ground-breaking research to overcome the hurdles associated with antibacterial food packaging, bringing it one step closer to market.

Dr Sharon Nelson-Barber | Infusing Mainstream STEM Education with Indigenous Culture, Language and Values
In the USA, approaches to Science, Technology, Engineering, and Maths (STEM) instruction are aligned with English-speaking, White middle-class norms. STEM courses rarely reflect consideration for the unique backgrounds of Indigenous learners. Because of this devaluing of local cultural, linguistic, and community traditions, whole communities are left behind, resulting in learners’ exclusion from advanced educational and employment tracks. Dr Sharon Nelson-Barber, Director of Culture and Language in STEM Education at WestEd, aims to change this trajectory. She and her team explore the ways in which students’ cultural backgrounds influence how they learn STEM subjects. Based on the team’s findings, they have developed innovative STEM education and assessment methods that shift relationships between Indigenous ways of learning and Western educational practices.

Professor Lieve Moons | Learning from Fish How to Re-build the Brain in Older Age
Worldwide, people are living longer lives. One outcome of this is that the prevalence of neurodegenerative diseases whereby the cells in the brain stop working or even die, is also increasing. Based in KU Leuven’s Department of Biology, Belgium, Professor Lieve Moons has been working to better understand how the central nervous system can regrow and repair, with a particular focus on ageing. Her work has important implications for identifying new therapeutic targets for neurorepair in elderly humans.

Dr Adam Szabo | Dr Alexander Marshak – DSCOVR: Monitoring Earth’s Climate and the Threat of the Sun’s Weather
The Deep Space Climate Observatory – DSCOVR – is a satellite orbiting between the Sun and Earth at the first Sun-Earth Lagrange point. The primary mission of DSCOVR is to measure the incoming solar wind conditions and provide these measurements in near-real-time, to enable space weather forecasting. DSCOVR also has instruments that can monitor Earth’s climate, by measuring energy reflected and radiated from Earth, and can track levels of ozone, aerosols, clouds, vegetation and ocean properties, and more. Led by scientists Dr Adam Szabo and Dr Alexander Marshak, the project is a joint mission between National Oceanic and Atmospheric Administration (NOAA), the US Air Force, and NASA.
