WORKING LIFE
LETTERS
BOOKS ET AL.
- Losing our taste for diversityAn emphasis on consistency and durability over variety and flavor has left many of our favorite foods in peril
- Public enemyPhysicist Fang Lizhi recounts his clashes with the Chinese regime and his role in the Tiananmen Square protests
POLICY FORUM
- Taking race out of human geneticsEngaging a century-long debate about the role of race in science
PERSPECTIVES
- The mite that jumped, the bee that traveled, the disease that followedGlobal expansion and trade contributed to the declining health of honeybees
- Throttling back the heart's molecular motorA small molecule inhibits mutated forms of myosin that cause cardiac hypertrophy
- Addressing an antiferromagnetic memoryAntiferromagnets could form a stable and robust platform for future spintronic technology
- Aging, alopecia, and stem cellsIntrinsic epigenetic status and extrinsic environmental factors affect hair follicle stem cells
- Nanoparticles meet their sticky endsHierarchical DNA structures direct the crystallization of gold nanoparticles
- Ice sheet in perilRadar data reveal how sensitive the Greenland Ice Sheet is to long-term climatic changes
- Alfred Gilman (1941–2015)A Nobel laureate's work on G proteins illuminated how signals are transmitted into cells
RESEARCH ARTICLE
- Hair follicle aging is driven by transepidermal elimination of stem cells via COL17A1 proteolysisDNA damage triggers the destruction of type XVII collagen, resulting in hair follicle stem cell depletion and hair loss.

REPORTS
- Nematicity in stripe-ordered cuprates probed via resonant x-ray scatteringNematicity has a temperature dependence that is distinct from that of a related structural distortion in lanthanum-based cuprates.
- Transmutable nanoparticles with reconfigurable surface ligandsDNA-coated gold nanoparticles can be controllably and tunably bonded or released from neighboring particles.
- Diamond family of nanoparticle superlatticesDNA origami is used to create sparsely packed gold nanoparticle superstructures.
- Electrical switching of an antiferromagnetTransport and optical measurements are used to demonstrate the switching of domains in the antiferromagnetic compound CuMnAs.
- Holocene deceleration of the Greenland Ice SheetStiffer ice means slower flow and less rapid thinning in the center of Greenland than in the past.
- Deformed wing virus is a recent global epidemic in honeybees driven by Varroa mitesPandemic virus infection in honeybees has been facilitated by the recent spread of a parasitic mite and by human trade.
- Europe’s forest management did not mitigate climate warmingReconstruction of 250 years of forest management history shows that Europe’s managed forests have contributed to climate warming.
- Biophysical climate impacts of recent changes in global forest coverThe biophysical effects of recent global forest cover change have caused measurable warming.
- Allele-specific inhibitors inactivate mutant KRAS G12C by a trapping mechanismA surprising mechanistic insight may lead to drugs targeting an oncogenic form of KRAS expressed in lung cancer.
- Structures of aminoarabinose transferase ArnT suggest a molecular basis for lipid A glycosylationStructural studies elucidate the mechanism of a reaction that contributes to antibiotic resistance in Gram-negative bacteria.
- Foxc1 reinforces quiescence in self-renewing hair follicle stem cellsDynamic expression of a transcription factor sustains the quiescent cellular state in activated hair follicle stem cells during self-renewal.
- A small-molecule inhibitor of sarcomere contractility suppresses hypertrophic cardiomyopathy in miceA small molecule that reduces cardiac muscle contraction prevents a certain type of heart disease in mice.
