Dr Hiroaki Nishiyama – A New Solution for Direct Laser Writing

Dr Hiroaki Nishiyama – A New Solution for Direct Laser Writing

Direct Laser Writing is a remarkably useful way to deposit intricately patterned materials onto surfaces. So far, however, the range of materials that can be used in the technique has been severely restricted. Now, Dr Hiroaki Nishiyama and his team at Yamagata University in Japan introduce an entirely new approach based on the unique properties of nanoparticles when suspended in a silver-based solution. When illuminated with ultra-short laser pulses, the setup can create highly stable patterns with sophisticated nanoscale structures – substantially broadening the range of materials available for use in the technique.

Dr Lara Hwa – The Links Between Stress, Signalling and Excessive Alcohol Consumption

Dr Lara Hwa – The Links Between Stress, Signalling and Excessive Alcohol Consumption

While alcohol is often consumed to help us relieve stress and relax, excessive consumption can negatively impact the way that our brains process and cope with stress, leading to further difficulties. Dr Lara Hwa from the Department of Psychology and Neuroscience at Baylor University is investigating the link between external stressors and stress signalling in the brain to understand how these processes govern excessive drinking.

The Wasting and Stunting Technical Interest Group: Generating Evidence to Challenge the Divide in Nutrition

The Wasting and Stunting Technical Interest Group: Generating Evidence to Challenge the Divide in Nutrition

Despite improvements in children’s nutrition over the past few decades, undernutrition remains a huge threat to the health and life of infants and young children worldwide. Health and nutrition actors have usually approached the problems of children being wasted, (thinner than they should be) and children who are stunted (shorter than they should be) as different outcomes of undernutrition with different causes and different interventions. Facilitated by the Emergency Nutrition Network (ENN), since 2014 the Wasting and Stunting Technical Interest Group (WaSt TIG) has challenged this view, and has begun to work to provide evidence for a unified approach to tackling these two outcomes of undernutrition.

Dr Egbert Giles Leigh, Jr – How Ecosystems are Built: Competition and Cooperation in Evolution

Despite the old adage ‘nice guys finish last’, cooperation is common in life – from the scale of genes or cells through to entire societies. Although these two ideas seem to contradict each other, Dr Egbert Giles Leigh Jr has demonstrated throughout his career at the Smithsonian Tropical Research Institute in Panama that working together has been the key to the success of multicellular life. Here, he explains his view of how competition and cooperation both played essential roles in bringing forth productive, diverse ecosystems.

Dr Edward Schwieterman – Developing a Guidebook to Search for Life Beyond Earth

Are we alone in the universe? Searching for life beyond our Solar System is one of the most ambitious efforts humans have ever undertaken. Because we do not have the ability to travel to distant exoplanets, scientists must rely on indirect clues that could help us find extraterrestrial life. Dr Edward Schwieterman and his colleagues at the University of California, Riverside, have been developing advanced methods to determine the habitability of planets and detect the elusive signs of life from afar.

Dr Kim de Mutsert – Identifying Effective Strategies to Protect Louisiana’s Precious Wetlands

Dr Kim de Mutsert – Identifying Effective Strategies to Protect Louisiana’s Precious Wetlands

The Louisiana coastal zone is the fastest-eroding wetland in the US. This region is home to a variety of vitally important fish species for local fishing industry and ecosystems, which are currently under threat. Conservation schemes have been proposed under the 2017 Louisiana Coastal Master Plan in an attempt to preserve coastal habitats and their inhabitants. Dr Kim de Mutsert of the University of Southern Mississippi and her colleagues use simulations to reveal how different management strategies will affect fish and shellfish up to 50 years from now.
