Biologists reveal how gyrase resolves DNA entanglements
Picture in your mind a traditional "landline" telephone with a coiled cord connecting the handset to the phone. The coiled telephone cord and the DNA double helix that stores the genetic material in every cell in the body have one thing in common; th.....»»
Microgravity-grown crystals reveal new insights into protein structures
Biochemists have long been working around a blind spot when it comes to proteins. They know that hydrogen constitutes nearly half of the atoms in proteins, but how they contribute to protein function in these complex structures has been less clear. H.....»»

How evolution has optimized the magnetic sensor in birds
Migratory birds are able to navigate and orientate with astonishing accuracy using various mechanisms, including a magnetic compass. A team led by biologists Dr. Corinna Langebrake and Prof. Dr. Miriam Liedvogel from the University of Oldenburg and t.....»»
Evolutionary biologists show that the color variants of female cuckoos are based on ancient mutations
Every cuckoo is an adopted child—raised by foster parents, into whose nest the cuckoo mother smuggled her egg. The cuckoo mother is aided in this subterfuge by her resemblance to a bird of prey. There are two variants of female cuckoos: a gray morp.....»»
New JWST observations reveal black holes rapidly shut off star formation in massive galaxies
New research published in Nature showcases new observations from the James Webb Space Telescope (JWST) that suggest black holes rapidly shut off star-formation in massive galaxies by explosively removing large amounts of gas......»»
Scientists reveal new path to increasing lactation for nursing mothers
Scientists at UC Santa Cruz have discovered a cellular process in the breast that can increase milk production by pregnant women, revealing a potential path to addressing lactation insufficiency syndrome—the inability of a nursing mother to produce.....»»
AI and physics combine to reveal the 3D structure of a flare erupting around a black hole
Scientists believe the environment immediately surrounding a black hole is tumultuous, featuring hot magnetized gas that spirals in a disk at tremendous speeds and temperatures. Astronomical observations show that within such a disk, mysterious flare.....»»
In Ecuadoran Amazon, butterflies provide a gauge of climate change

Seeing is believing: Scientists reveal connectome of the fruit fly visual system
Janelia scientists and collaborators have reached another milestone in connectomics, unveiling a comprehensive wiring diagram of the fruit fly visual system. The work has been released on the pre-print server bioRxiv......»»
Researchers reveal sources of black carbon in southeastern Qinghai-Tibet plateau
Black carbon (BC) is the result of incomplete combustion of fossil fuels and biomass, with strong light absorption. It is second only to carbon dioxide as a climate-forcing factor for atmospheric warming. Deposition of BC on snow and ice surfaces red.....»»
Dramatic burning of royal remains reveals Maya regime change
New archaeological investigations in Guatemala reveal that ancient Maya peoples did not just passively watch their dynastic systems collapse at the end of the Classic period. They actively reworked their political systems to create new governments......»»
