Nuclear power is considered one of the ways to reduce dependence on fossil fuels, but how to deal with nuclear waste products is among the issues surrounding it. Radioactive waste products can be turned into more stable elements, but this process is not yet viable at scale. New research led by physicists from the University […]
One of the most recurrent (and most disputed) headers during the last half century in the debates about whether cosmology points to some ‘fundamental purpose’ of the universe is (I didn’t need to say it) the (ill-)famous anthropic principle . Many versions of it have been formulated since it was so named in the 70’s […]
Stone Age travel story emerges from DNA of “Vittrup Man” Advanced analysis of DNA, teeth and bones of the bog-preserved body of Denmark’s “Vittrup Man” has revealed the individual’s history as well as possible movements and connections between Stone Age cultures. Vittrup Man’s genetics suggest an origin on the Scandinavian Peninsula, where he likely grew […]
Global energy demand is expected to rise around 30% by 2040 according to the International Energy Agency (IEA). Hydrogen (H2) produced by the electrolysis of water, using renewable electricity, the so-called green hydrogen, has emerged as a promising energy vector to respond to this increasing energy demand with the potential to decarbonize transportation, heating, and […]
Digital technologies have gained an essential role in societies’ development, by generating a global transformation in economic, social, and environmental dimensions. Digitalization does not just bring comfort and effectiveness in daily life but also contributes to equity and opportunities generation. However, this digital transformation is raising a fierce debate on how to ensure a positive […]
In most materials, heat prefers to scatter. If left alone, a hotspot will gradually fade as it warms its surroundings. But in rare states of matter, heat can behave as a wave, moving back and forth somewhat like a sound wave that bounces from one end of a room to the other. In fact, this […]
Iceland volcano’s magma hits unprecedented speed Magma underneath Iceland’s Reykjanes peninsula flows at an “ultra-rapid” 7,400 cubic meters per second, and the same magma river likely caused Thursday’s eruption. The unprecedented speed indicates the role of not only pressure but also tectonic stress and ground fracturing in a volcano’s likelihood to erupt, says Sigrun Hreinsdottir […]
The way a particular reaction proceeds, described in terms of the steps involved, is called mechanism. The study of organic chemistry is, to a great extent, the study of reaction mechanisms and textbooks content both their description and their applications. But something has come to revolutionize the world of mechanisms: surface chemistry. On-surface synthesis is […]
Have you ever wondered what chickens are talking about? Chickens are quite the communicators — their clucks, squawks and purrs are not just random sounds but a complex language system. These sounds are their way of interacting with the world and expressing joy, fear and social cues to one another. Like humans, the “language” of […]
