Kavli Affiliate: Jia Liu | First 5 Authors: Mingxuan Du, Jia Liu, Xiao-Ping Wang, Tianhao Wu, | Summary: We investigate the enhancement of dark sector particle production within the scattering dominant regime. These particles typically exhibit a slight mixing with Standard Model particles through various portals, allowing for their generation through in-medium oscillation from Standard […]
Kavli Affiliate: Giordano Scappucci | First 5 Authors: Kenta Takeda, Akito Noiri, Takashi Nakajima, Leon C. Camenzind, Takashi Kobayashi | Summary: Silicon-based spin qubits offer a potential pathway toward realizing a scalable quantum computer owing to their compatibility with semiconductor manufacturing technologies. Recent experiments in this system have demonstrated crucial technologies, including high-fidelity quantum gates […]
Kavli Affiliate: Jeffrey Moses | First 5 Authors: Jiaoyang Zheng, Guru Khalsa, Jeffrey Moses, , | Summary: We observe strongly anisotropic third-harmonic generation mediated by resonant sum-frequency driving of Raman phonons with THz light, extending light-induced dual control of structural and optical properties in solids. Either strong enhancement or strong suppression of the third harmonic […]
Kavli Affiliate: Jeffrey Moses | First 5 Authors: Jiaoyang Zheng, Guru Khalsa, Jeffrey Moses, , | Summary: We demonstrate a strong, elastic, frequency-upshifting optical polarizability that accompanies sum-frequency driving of Raman phonons and two-photon absorption, extending the duality of structural and optical property modification recently observed in light-driven phononics. The effect, phonon-dressed third-harmonic generation (THG), […]
Kavli Affiliate: Roderick MacKinnon | Authors: Maria Elizabeth Falzone and Roderick MacKinnon | Summary: PLCβ enzymes cleave PIP2 producing IP3 and DAG. PIP2 modulates the function of many ion channels, while IP3 and DAG regulate intracellular Ca2+ levels and protein phosphorylation by protein kinase C, respectively. PLCb enzymes are under the control of GPCR signaling […]
Kavli Affiliate: Reza Shadmehr | Authors: Erik M. Summerside, Robert J Courter, Reza Shadmehr and Alaa A. Ahmed | Summary: As people age, they move slower. Is age-related reduction in vigor a reflection of a reduced valuation of reward by the brain, or a consequence of increased effort costs by the muscles? Here, we quantified […]
Kavli Affiliate: David Kleinfeld | Authors: Harish Kannan, Paul Sun, Tolga Çağlar, Pantong Yao, Brian R Taylor, Kinshuk Sahu, Daotong Ge, Matteo Mori, Mya Warren, David Kleinfeld, JiaJia Dong, Bo Li and Terence Hwa | Summary: Bacterial colony growth on hard agar is commonplace in microbiology; yet, what occurs inside a growing colony is complex […]
Kavli Affiliate: Michael Keiser | Authors: William J. Connell, Kristle Garcia, Hani Goodarzi and Michael J. Keiser | Summary: Chemical probes interrogate disease mechanisms at the molecular level by linking genetic changes to observable traits. However, comprehensive chemical screens in diverse biological models are impractical. To address this challenge, we developed ChemProbe, a model that […]
Kavli Affiliate: Timothy Brown | Authors: Richard J McDowell, Altug Didikoglu, Tom Woelders, Mazie J Gatt, Roelof A. Hut, Timothy M Brown and Robert J Lucas | Summary: Background Light is a key environmental regulator of physiology and behaviour. Mistimed or insufficient light disrupts circadian rhythms and is associated with impaired health and well-being across […]
Kavli Affiliate: Cynthia F. Moss | Authors: Michael A Pardo, Kurt Fristrup, David S Lolchuragi, Joyce Poole, Petter Granli, Cynthia Moss, Iain Douglas-Hamilton and George Wittemyer | Summary: Personal names are a universal feature of human language, yet few analogs exist in other species. While dolphins and parrots address conspecifics by imitating the calls of […]
