  • 91530 From 2D to 1D: Atomically quasi '1D' wires using a carbon nanotube template
    Researchers have used carbon nanotube templates to produce nanowires of transition metal monochalcogenide (TMM), which are only 3 atoms wide in diameter. These are 50 times longer than previous attempts and can be studied in isolation, preserving the properties of atomically quasi '1D' objec... [anonymous]
  • 91529 High performance solid-state sodium-ion battery
    Solid-state sodium-ion batteries are far safer than conventional lithium-ion batteries, which pose a risk of fire and explosions, but their performance has been too weak to offset the safety advantages. Researchers have now reported developing an organic cathode that dramatically improves both stab... [anonymous]
  • 91528 Thermodynamic magic enables cooling without energy consumption
    Physicists have developed an amazingly simple device that allows heat to flow temporarily from a cold to a warm object without an external power supply. Intriguingly, the process initially appears to contradict the fundamental laws of physics. [anonymous]
  • 91527 Continuing impacts of Deepwater Horizon oil spill
    Nine years ago tomorrow -- April 20, 2010 -- crude oil began leaking from the Deepwater Horizon drilling rig into the Gulf of Mexico in what turned out to be the largest marine oil spill in history. A long-term study suggests the oil is still affecting the salt marshes of the Gulf Coast, and reveals... [anonymous]
  • 91526 A universal framework combining genome annotation and undergraduate education
    Scientists and educators have developed a framework for using new genome sequences as a training resource for undergraduates interested in learning genome annotation. This strategy will both make the process of determining gene functions more efficient and help train the next generation of scientis... [anonymous]
  • 91525 Discovery may help explain why women get autoimmune diseases far more often than men
    New evidence points to a key role for a molecular switch called VGLL3 in autoimmune diseases, and the major gap in incidence between women and men. Building on past research showing that women have more VGLL3 in their skin cells than men, a team studied it further in mice. They show that having too ... [anonymous]
  • 91524 Warming: Plants are also stressed out
    What will a three-degree-warmer world look like? When experiencing stress or damage from various sources, plants use chloroplast-to-nucleus communication to regulate gene expression and help them cope. Now, researchers have found that GUN1 -- a gene that integrates numerous chloroplast-to-nucleus re... [anonymous]
  • 91523 New method to detect off-target effects of CRISPR
    Since the CRISPR genome editing technology was invented in 2012, it has shown great promise to treat a number of intractable diseases. However, scientists have struggled to identify potential off-target effects in therapeutically relevant cell types, which remains the main barrier to moving therapie... [anonymous]
  • 91522 Through thick and thin: Neutrons track lithium ions in battery electrodes
    Lithium-ion batteries are expected to have a global market value of $47 billion by 2023, but their use in heavy-duty applications such as electric vehicles is limited due to factors such as lengthy charge and discharge cycles. Engineers are examining how the lithium moves in battery electrodes, imp... [anonymous]
  • 91521 Mysterious river dolphin helps crack the code of marine mammal communication
    The Araguaian river dolphin of Brazil was thought to be solitary with little social structure that would require communication. But researchers have discovered the dolphins actually are social and can make hundreds of different sounds, a finding that could help uncover how communication evolved in m... [anonymous]
