Hydrogen? Just add water and sunlight
Hydrogen has been sold to the public as having the potential to be the ultra-clean fuel for the future’s economy. What’s less likely to be mentioned is that 96% of hydrogen is produced from natural gas, coal or other fossil fuels – producing it using renewable electricity is simply too expensive. To realise hydrogen’s full potential, the world needs better […]
Facilitated ion transfer through liquid-liquid interfaces
The migration of charged ions through interfaces between immiscible liquids plays an important role in several natural and technological processes. Prof Akihiro Morita of Tohoku University in Japan uses molecular dynamics simulations to develop models of the complex phenomena involved in the motion of ions across interfaces under the effect of external electric fields. This powerful approach is providing detailed […]
New Toolkits for Positron Emission Tomography
Positron emission tomography (PET) is a powerful imaging technique that uses radiotracers injected into the body to look at biology in tissues and cells, making it an important tool in biomedical research and drug development. Dr Victor Pike, Chief of the PET Radiopharmaceutical Sciences Section of the Molecular Imaging Branch at the National Institute of Mental Health in the U.S., […]
Directed Panspermia: Synthetic DNA in bioforming planets
As our technological advancements continue, scientists are beginning to turn what was science fiction into reality. Concepts such as terraforming and travel between stars are becoming more achievable, giving life to the dream that one day we might colonise other planets. Directed panspermia is one method of altering a hostile, uninhabited planet to a more Earth-like environment, and Cork Institute […]
Industrial-Academic collaboration: The key for C-H bond activation
A very hot and current scientific topic is the synthesis of active pharmaceutical ingredients (APIs), the burning question being “how can we make API synthesis efficient?”. A big step towards the answer was taken by Dr Guillaume Journot, senior scientist at Servier, France, and Dr Jean-François Brière, a CNRS senior research scientist at COBRA laboratory in Rouen, France. They proved […]
Amino acids bombarded with ionising radiation – what breaks first?
Ionising radiation, including high-energy electrons, is usually something best avoided. However, nuclear accidents and even medical tools mean that human tissue is occasionally exposed to it. After the ‘Atomic Age’ of the mid-1900s, understanding the effect of radiation on the human body has been recognised as of paramount importance. Dr Jelena Tamuliene’s most recent research at Vilnius University is into […]
Tracking changing shapes in falling raindrops
Raindrops can adopt remarkably similar shapes, sizes and movements as they fall to the ground, but so far, our understanding of their behaviour has remained far from complete. Through her research, Dr Merhala Thurai at Colorado State University uses innovative techniques to learn more about what happens as they fall, particularly during stormy weather. Her team’s work offers important new […]
An introduction to the information dimension
The difficulty of defining the true nature of information has sparked a rich, seemingly unending variety of questions over the past centuries; from the nature of the human soul to whether artificial intelligence can gain consciousness. Now Daniel Boyd, an independent researcher in the Netherlands, believes that these problems could be solved if we view information as a substance residing […]
A trick of the light: Discovering Dark-Bright and Anti-Dark-Bright Solitons
Light has many incredible properties. They range from its strange duality of behaviour, acting either as a wave or a particle, to demonstrating incredible nonlinear effects that can be exploited with laser and optical technologies. One such property is the ability of light waves to form solitons when they pass through materials like optical fibres. Solitons, or solitary waves, occur […]
Discovering perfect squares and building square roots
Mathematicians have been faced with the problem of finding perfect squares and their roots since ancient times. Recent findings in computational number theory have enabled the development of efficient algorithms for discovering square numbers. Professor Philip Brown from the Department of Foundational Sciences (Mathematics) at Texas A&M University Galveston Campus has developed a new algorithm that can detect a perfect […]
