Phys.org / Fossil plankton shells reveal reduced nitrogen fixation in warmer oceans 3 million years ago
Nitrogen is a key nutrient because it fuels the growth of plankton, which forms the basis of the marine food web. Two opposing processes determine the global nitrogen cycle: nitrogen fixation and denitrification.
Phys.org / A finely tuned mess—how disorder can make networks more stable
Perfection is overrated—at least when it comes to complex systems like the power grid, food webs and advanced materials. For decades, scientists generally assumed that networks function most reliably when their individual ...
Phys.org / Ubiquitin marks abnormal glycogen for destruction to protect the brain, study finds
Researchers at the University of Cambridge and the MRC Laboratory of Molecular Biology have discovered a previously unknown cellular defense system that protects the brain from abnormal glycogen accumulation, which is linked ...
Phys.org / New krypton-88 data narrow a key gap in stellar strontium models
An international research team has reported the first experimental investigation of a nuclear physics reaction essential for understanding how the element strontium is produced in stars—specifically in stellar environments ...
Phys.org / Chemists overturn 40-year assumption about a key class of superconductors
Scientists at Warwick have shown that a material treated for 40 years as a uniform, textbook superconductor is in fact a patchwork of different crystal structures throughout its bulk, using an advanced 3D imaging technique ...
Medical Xpress / Children's pupils may reveal shifting attention in ADHD, especially when off medication
The eyes are more than lenses to the outside world; they can also be windows that offer a glimpse into what's happening inside our bodies. What if the eyes could help us understand how attention shifts from one moment to ...
Phys.org / Grass and clover can provide more than animal feed
Growing leys—grass and clover—is nothing new in Swedish agriculture. But in the arable farming regions dominated by cereal production, leys are less common. One reason is that there needs to be a market for what is harvested.
Phys.org / Laser scans reveal 23 hidden ship carvings on Bronze Age temple wall in Cyprus
About 40 years ago, researchers found ancient ship carvings on a temple wall in Cyprus, possibly all carved at once at the tail end of the Bronze Age, around the time of the infamous Bronze Age collapse. Then, decades later, ...
Phys.org / Newfound fungal nutrient-sensing mechanism could advance biofuels and disease control
Scientists have taken a step toward a better understanding of how fungi sense and respond to nutrients in the environment, which is critical for engineering fungi for green technologies and combating fungal pathogens and ...
Tech Xplore / Why AI consciousness could become the next great societal divide
The debate about AI consciousness is growing in academic articles, newspaper opinion pieces and even among AI bots themselves. I doubt this is a passing wave of interest.
Phys.org / Why global wind energy may stay steady even as storm tracks shift poleward
Understanding how wind changes in response to global warming is necessary for accurately modeling climate and weather, identifying risks to infrastructure, and assessing global wind power capacity.
Phys.org / A new bridge for quantum networks: Physicists convert microwaves to light using 2D magnets
Physicists at The City College of New York have demonstrated a new way to transfer microwave signals onto light using magnetic waves inside a layered semiconductor. The work establishes a materials platform for building interfaces ...
