  • 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 stability and energy density.... Read more »
  • 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.... Read more »
  • 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... Read more »
  • 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 scientists in bioinformatics.... Read more »
  • 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... Read more »
  • From 2D to 1D: Atomically quasi '1D' wires using a carbon nanotube template
    (Tokyo Metropolitan University) Researchers from Tokyo Metropolitan University 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'... Read more »
  • Researchers report high performance solid-state sodium-ion battery
    (University of Houston) 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 Friday reported developing an organic cathode that dramatically improves both stability and energy density.... Read more »
  • Plants are also stressed out
    (Salk Institute) 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, Salk Institute researchers have found that GUN1 -- a gene that integrates numerous chloroplast-to-nucleus retrograde signaling pathways -- also plays... Read more »
  • Molecular target UNC45A is essential for cancer but not normal cell proliferation
    (Medical College of Georgia at Augusta University) Identifying a protein that plays a key role in cancer cell growth is a first step toward the development of a targeted cancer therapy. It is especially promising when this protein is dispensable for the growth of normal cells. Their discovery that UNC45A... Read more »
  • Through thick and thin: Neutrons track lithium ions in battery electrodes
    (University of Virginia School of Engineering and Applied Science) 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. UVA Engineering researchers working... Read more »
