Chronobiology of Cancer: How Aging Fuels Oncogenesis at the Molecular Level
Aging and Cancer, EarlyView.This graphical abstract illustrates the key biological pathways linking aging with cancer development and progression. In the upper left, cumulative exposure to ultraviolet radiation, toxins, and reactive oxygen species (ROS) causes DNA damage and genomic instability, whereas age‐related decline in repair mechanisms, such as ATM/ATR, BER, and NER ...

Wildlife Society Bulletin, 2016 Accurately estimating cougar (Puma concolor) density is usually based on long‐term research consisting of intensive capture and Global Positioning System collaring efforts and may cost hundreds of thousands of dollars annually.

Use of radio‐linked VHF technology to monitor neonate carnivores
Wildlife Society Bulletin, 2023 Fine‐scale monitoring of neonate mammals can provide important data about survival rates and cause‐specific mortality. However, the VHF transmitters and collars frequently used to monitor neonate mammals necessitate logistically intensive field efforts ...

RSF1‐Dependent PAR Turnover Promotes 53BP1 Liquid Condensate Formation at DNA Damage Sites
Advanced Science, EarlyView.At sites of DNA damage, RSF1 recruits PARG to accelerate PAR turnover, triggering a switch from PAR‐driven condensates to 53BP1 condensates. This condensate transition enables p53‐dependent gene transcription and coordinates the DNA damage response.

Advanced Science, EarlyView.Glucocorticoids (GC) are widely used to reduce inflammation. We show that the glucocorticoid receptor in myeloid cells regulates macrophage cell cycle and genome integrity during muscle regeneration. We demonstrate that dexamethasone administration during the early inflammatory phase delays muscle repair by increasing macrophage proliferation ...

Less invasive monitoring of cougars in Colorado's front range
Wildlife Society Bulletin, 2019 From 2014 to 2016, in the Front Range of Colorado, USA, we assessed noninvasive approaches to sampling cougar (Puma concolor) populations in an attempt to provide a new method that would be less field intensive, less expensive, and could be applied over ...

Exploiting Ferroelectric and Spintronic Dynamics for Neural Network Computation
Advanced Intelligent Systems, EarlyView.Ferroelectric and spintronic devices, relying on the control of polarization and magnetization, offer intrinsically fast, durable, energy‐efficient, and low‐latency building blocks for analog in‐memory computing. The hysteretic dynamics of an order parameter are leveraged to provide nonvolatile, multistate memory and nonlinear switching. Brain‐inspired

Do GPS clusters really work? carnivore diet from scat analysis and GPS telemetry methods
Wildlife Society Bulletin, 2011 Global Positioning System (GPS) data collected using radiocollars have allowed researchers to identify sites where predators have killed prey, but this method has yet to be compared with scat analysis, a more traditional method of determining diet ...

Energy‐Aware Perturbation Optimization for Memristor‐Array Convolutional Neural Networks
Advanced Intelligent Systems, EarlyView.Memristor‐array inference becomes more energy efficient when layer inputs are reshaped before computation. Sinusoidal perturbation encoding with dual‐threshold screening reduces active voltage pulses and contracts ADC input‐current ranges, jointly lowering crossbar and peripheral energy while preserving accuracy across hardware MNIST validation, deep ...

, 2022 Cougars make a living by not being seen. In areas disturbed by humans, these cats are most active at dusk and early in the morning. In low-light conditions, cougars see up to six times better than humans.
