Perspectives


Planetary Science

Are the right chemical ingredients enough to make a habitable planet?


HIV

Immunogens are designed to elicit the production of highly coveted broadly neutralizing antibodies that protect against HIV-1 [Also see Report by McGuire et al.]


Cancer

Tiny changes in our genomes can enhance oncogene expression and contribute to tumorigenesis [Also see Report by Mansour et al.]


Ultrafast Dynamics

Quantum-mechanical tunneling of valence-band electrons excited by intense, ultrafast laser pulses is verified with time-resolved x-ray spectroscopy [Also see Report by Schultze et al.]


Epidemiology

How can models provide better insights into pathogen emergence and epidemic prediction?


Neurodevelopment

Dead stem cells are expelled from the vertebrate brain


Genetics

Evolutionary analysis shows how a mammalian iron transport protein evolves to avoid capture by bacteria [Also see Report by Barber and Elde]



Reports


Nanogranular microstructures found in simulated carbonate faults control the physical sliding mechanism during rupture.


First-principles calculations are used to predict an exotic effect in a particular structure of WTe2 and related materials.


Excited electrons in semiconducting silicon are tracked on a time scale faster than the lattice vibrations. [Also see Perspective by Spielmann]


Smooth surface, crystalline 3D metallic nanostructures are fabricated using a laser shock imprinting technique.


Crystalline sheets exfoliated from layered metal-organic framework materials are formed into selective membranes.


Early 20th century agricultural changes initiated the decline of a variety of insect pollinators in Britain.


The primate iron transport protein and a bacterial transferrin surface receptor are in an evolutionary battle for iron. [Also see Perspective by Armitage and Drakesmith]


Contact with minorities, coupled with discussion of issues pertinent to them, can produce lasting opinion change.


Signaling dynamics increase the information transmission capacity of biochemical signaling pathways.


Leukemia-associated mutations drive cell growth by creating a powerful transcriptional enhancer upstream of an oncogene. [Also see Perspective by Vähärautio and Taipale]


A new support for biological specimens improves the resolution that can be achieved by electron microscopy.


Higher affinities let narrow neutralizing HIV antibodies outcompete broadly neutralizing HIV antibodies early in infection. [Also see Perspective by Ofek and Diskin]
