  • Earth-air heat exchanger best way to protect farm animals in livestock buildings against the effects of climate change
    Without countermeasures, climate change will negatively impact animals in pig and poultry production. Beside the health and wellbeing of the animals, heat stress also affects performance and, as a result, profitability. As the animals are predominantly kept in confined livestock buildings equipped with mechanical ventilation systems, researchers examined the inlet... Read more »
  • Scientists develop artificial photosynthesis device for greener ethylene production
    A newly developed device could reduce the carbon footprint of ethylene production, report scientists.... Read more »
  • Small but distinct differences among species mark evolution of human brain
    The most dramatic divergence between humans and other primates can be found in the brain, the primary organ that gives our species its identity. However, all regions of the human brain have molecular signatures very similar to those of our primate relatives, yet some regions contain distinctly human patterns of... Read more »
  • World's smallest tape recorder is built from microbes
    Through a few clever molecular hacks, researchers have converted a natural bacterial immune system into a microscopic data recorder, laying the groundwork for a new class of technologies that use bacterial cells for everything from disease diagnosis to environmental monitoring.... Read more »
  • How badly do you want something? Babies can tell
    Babies as young as 10 months can assess how much someone values a particular goal by observing how hard they are willing to work to achieve it, according to a new study. This ability requires integrating information about both the costs of obtaining a goal and the benefit gained by... Read more »

  • Physicists develop faster way to make Bose-Einstein condensates
    (Massachusetts Institute of Technology) MIT physicists have invented a new technique to cool atoms into condensates, which is faster than the conventional method and conserves a large fraction of the original atoms. The team used a new process of laser cooling to cool a cloud of rubidium atoms all the... Read more »
  • Comparison of primate brains hints at what makes us human
    (American Association for the Advancement of Science) A detailed comparative analysis of human, chimpanzee and macaque brains reveals elements that make the human brain unique, including cortical circuits underlying production of the neurotransmitter dopamine.... Read more »
  • Push to twist: Achieving the classically impossible in human-made material
    (American Association for the Advancement of Science) Researchers have designed a metamaterial that can twist to the right or the left in response to a straight, solid push.... Read more »
  • Research reveals China's reversing emission flows
    (University of East Anglia) The flow of China's carbon emissions has reversed according to new research led by scientists at the University of East Anglia (UEA).The study estimates the carbon implications of recent changes in the country's economic development patterns and role in international trade since the global financial crisis....
